Description

Technical Field

[0001] The present invention belongs to the technical field of injection molding of viscous materials, and particularly relates to a multi-channel injection molding system for viscous materials. Background Art

[0002] In the process of resource utilization of the muck excavated by a shield, it is necessary to pour the viscous material formed by mixing the shield muck and an admixture into building materials products with various geometric shapes to realize the resource conversion from the discarded muck to green products. Since the mixed material has high viscosity and plastic deformation characteristics, to process it into building materials products with specific geometric shapes, the material needs to be poured into a mold.

[0003] In the prior art, a vacuum extrusion device is used to realize the injection molding of the material. However, the disadvantage of the prior art is that such a vacuum extrusion device has high requirements for the characteristics of the injected material, and the mixed material needs to be in a loose state. Therefore, it is difficult for the vacuum extrusion device in the prior art to perform molding treatment on materials with high viscosity and plastic deformation characteristics.

[0004] Therefore, it is necessary to provide a new multi-channel injection molding system for viscous materials to solve the above technical problems. Summary of the Invention

[0005] Based on this, the present invention provides a multi-channel injection molding system for viscous materials to solve the technical problem that existing equipment cannot achieve rapid injection molding of viscous materials.

[0006] To solve the above technical problems, the present invention provides a multi-channel injection molding system for viscous materials, including a blanking support frame. A injection molding barrel is arranged inside the blanking support frame. The multi-channel injection molding system for viscous materials further includes a synchronous lifting device for controlling the lifting of the injection molding barrel. The lower end of the injection molding barrel is an outlet, and a multi-channel injection valve is arranged at the outlet. The side of the injection molding barrel has an inlet, and the inlet is communicated with a pumping and inputting material assembly through a section of hose. A screw feeder for extruding the material is arranged at the upper end of the injection molding barrel. The multi-channel injection molding system for viscous materials further includes a combined multi-unit mold used in cooperation with the multi-channel injection valve. The multi-channel injection valve has a plurality of independent injection channels, and the combined multi-unit mold has a plurality of independent product molding cavities corresponding to the injection channels. Below the multi-channel injection valve is a mold access channel. The multi-channel injection molding system for viscous materials includes a conveying platform for conveying the combined multi-unit mold, and the conveying platform penetrates the blanking support frame along the direction of the mold access channel. The multi-channel injection molding system for viscous materials further includes a finishing device arranged on one side of the blanking support frame.

[0007] Compared with the prior art, the multi-channel injection molding system for viscous materials of the present invention has the following advantages: By using the multi-channel injection molding system for viscous materials of the present invention, the technical problem that the viscous muck materials are sticky after being mixed with the admixture and need to be rapidly molded can be solved. In the case of using the single-cavity multi-channel injection method, multi-channel uniform discharging can be achieved, rapid injection molding of viscous materials can be realized, and different injection times can be set according to the viscosity of the materials during the injection process to ensure that the surface of the multi-connected mold is smooth and the on-site secondary waste is extremely small.

[0038] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation mode of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0039] The following combines the attached Figures 1 - 23A further description is given to the multi-channel injection molding system for viscous materials of the present invention.

[0040] The following combines the attached Figures 1 - 9 The overall structure of the present invention will be described. The present invention discloses a multi-channel injection molding system for viscous materials, including a blanking support frame 14. Inside the blanking support frame 14, there is an injection molding barrel 15. The multi-channel injection molding system for viscous materials further includes a synchronous lifting device 17 for controlling the lifting of the injection molding barrel 15. The lower end of the injection molding barrel 15 is an outlet 151, and a multi-channel injection valve 400 is provided at the outlet 151. The side of the injection molding barrel 15 has an inlet 152, and the inlet 152 is communicated with a pumping input material assembly 19 through a section of hose 18. A screw feeder 20 for extruding materials is provided at the upper end of the injection molding barrel 15. The multi-channel injection molding system for viscous materials further includes a combined multi-unit mold 300 used in cooperation with the multi-channel injection valve 400. The multi-channel injection valve 400 has a plurality of independent injection channels, and the combined multi-unit mold 300 has a plurality of independent product forming cavities 5 corresponding to the injection channels. Below the multi-channel injection valve 400 is a mold access channel. The multi-channel injection molding system for viscous materials includes a conveying platform 30 for conveying the combined multi-unit mold 300. The conveying platform 30 penetrates the blanking support frame 14 along the direction of the mold access channel. The multi-channel injection molding system for viscous materials further includes a finishing device provided on one side of the blanking support frame 14. More specifically, the number of injection channels is the same as the number of product forming cavities 5, and their positions are arranged in one-to-one correspondence. The injection molding barrel 15 is used to hold materials.

[0041] In this embodiment, the blanking support frame 14 is used to support the injection molding barrel 15 and the upper components. The synchronous lifting device 17 jacks up the top frame 16 to achieve the straight up and down movement of the injection molding barrel 15. The synchronous lifting device 17 is a prior art. The synchronous lifting device 17 includes four worm and gear elevators 171 connected end to end and a synchronous motor 172 for driving the lifting of the worm and gear elevators 171. Each worm and gear elevator 171 includes a jacking rod 1711. The worm and gear elevator 171 is an existing off-the-shelf component, and the structure of the synchronous lifting device 17 is also a prior art, so its structure will not be elaborated here. The finishing device is used to scrape and finish the formed building products, which can improve the surface quality of the building products. The conveying platform 30 is used to convey the combined multi-unit mold 300.

[0042] Since the injection molding barrel 15 needs to move up and down, the pipeline directly connected to the injection molding barrel 15 is set as a flexible hose 18. When the injection molding barrel 15 moves up and down, one end of the flexible hose 18 can move along, ensuring that the flexible hose 18 is always in a connected state. In addition, when the pumping input material assembly 19 works, it will emit vibrations. Using the flexible hose 18 can also prevent the vibrations from being directly transmitted to the injection molding barrel 15, reducing the influence of the vibrations of the pumping input material assembly 19 on the injection molding barrel 15.

[0043] During use, the combined multi-cavity mold 300 is placed below the multi-channel injection valve 400. The material enters the injection molding barrel 15 from the pumping input material assembly 19 through the flexible hose 18. The screw feeder 20 is used to provide a downward spiral force. The switch of the multi-channel injection valve 400 is opened, so that the material in the injection molding barrel 15 flows out from the discharge port 151 and is injected into the combined multi-cavity mold 300 through the multi-channel injection valve 400. After the cavities of the combined multi-cavity mold 300 are filled, the synchronous lifting device 17 operates to move the injection molding barrel 15 as a whole upward by a certain distance, disconnecting the bonded material between the multi-channel injection valve 400 and the combined multi-cavity mold 300. Then, the combined multi-cavity mold 300 is removed, and an empty combined multi-cavity mold 300 is pushed in. The injection molding barrel 15 is moved upward as a whole to the top of the combined multi-cavity mold 300, and then injection is carried out through the multi-channel injection valve 400. By repeating the above steps, continuous injection of the fluid plastic material can be realized to form the required building products. With the structure of the present invention, pressurized injection can be achieved, which is suitable for the injection molding of viscous materials. During use, the screw feeder 20 is used to control the flow rate of the material. The multi-channel injection valve 400 has multiple independent discharge channels and can simultaneously inject materials into multiple cavities of the mold, greatly improving the molding efficiency.

[0044] According to the specific embodiment of the present invention, the conveying platform 30 is provided with roller assemblies 27 distributed in a dot pattern and used to support the combined multi-cavity mold 300. The position of the conveying platform 30 directly facing the multi-channel injection valve 400 is the injection station. The conveying platform 30 further includes a first-stage pushing cylinder 28 for pushing the combined multi-cavity mold 300 into the injection station, and the conveying platform 30 further includes a second-stage pushing cylinder 29 for pushing the combined multi-cavity mold 300 out of the injection station. More specifically, the roller assembly 27 includes a roller seat fixed to the conveying platform 30 and a roller body rotatably connected to the roller seat.

[0045] In this embodiment, the roller assemblies 27 are arranged in a dot pattern, which can not only ensure the basic function of roller conveying, but also have the following beneficial effects. On the one hand, it provides space for installing the push cylinder, which is conducive to simplifying the structure of the conveying platform 30. On the other hand, when the present invention is in use, it is inevitable that some sticky materials will fall on the conveying platform 30. By using the roller assemblies 27 arranged in a dot pattern, the probability of the materials sticking to the surface of the roller assemblies 27 can be reduced, which can ensure the smooth rotation of the roller body and is also conducive to the cleaning of the conveying platform 30. More specifically, a vibrating platform 26 is provided at the tail end (discharge end) of the conveying platform 30 close to the material passage. During specific implementation, for materials with slightly poor fluidity, the vibrating platform 26 can be vibrated to vibrate and compact the materials in the combined multi-station mold 300. More specifically, the multi-channel injection molding system for sticky materials further includes a control console and an electrical control system, and the electrical control system is used to automatically control the moving parts in the present invention, and the control console is conducive to realizing centralized control.

[0046] According to the specific embodiment of the present invention, the blanking support frame 14 is in the shape of a rectangular frame as a whole, and the injection molding barrel 15 is in the shape of a rectangular frame that penetrates up and down as a whole. A top frame 16 is provided at each of the four corners of the injection molding barrel 15. In this embodiment, the structure of the injection molding barrel 15 is rectangular, which matches the shape of the rectangular mold. The force of the ejector rod 1711 is transmitted through the top frames 16 at the four corners of the injection molding barrel 15, which is conducive to improving the uniformity of force and ensuring the stable lifting of the injection molding barrel 15.

[0047] Please refer to Figures 5 - 6 , according to the specific embodiment of the present invention, below the multi-channel injection valve 400 is the mold access channel. A set of side limit assemblies are respectively provided on both sides of the injection molding barrel 15 along the direction of the mold access channel. The side limit assembly includes a limit bracket 21. One end of the limit bracket 21 is installed on the top of the blanking support frame 14, and the other end of the limit bracket 21 is provided with a limit roller 22. The limit roller 22 is rotatably connected to the limit bracket 21, and the limit rollers 22 in the two sets of side limit assemblies respectively abut against the outer side wall of the injection molding barrel 15 from two opposite directions.

[0048] In use, the mold inlet and outlet channels are used for the inlet and outlet of the combined multi-station mold 300. When the combined multi-station mold 300 is filled with viscous material, since there is still some sticky material adhering between the multi-channel injection valve 400 and the mold, a certain lateral pulling force will be exerted on the bottom of the multi-channel injection valve 400 when the mold is removed. In this embodiment, by providing the side limiting assembly, the injection molding barrel 15 can be limited along the direction of the mold inlet and outlet channels, which can effectively limit the positions of the injection molding barrel 15 and the multi-channel injection valve 400 and resist the influence brought by the movement of the mold on the injection molding barrel 15. During limiting, the limiting roller 22 abuts against the outer side wall of the injection molding barrel 15. The limiting roller 22 can rotate around its own axis. Therefore, it will not affect the free up and down movement of the injection molding barrel 15.

[0049] Please refer to Figure 9 , according to the specific embodiment of the present invention, the limiting bracket 21 includes two inclined limiting inclined rods 211. One end of the two limiting inclined rods 211 in the same direction is provided with a limiting horizontal mounting plate 212. Two waist-shaped holes 213 are provided on the limiting horizontal mounting plate 212. The other ends of the two limiting inclined rods 211 in the same direction are provided with two hinge seats 214 side by side. Each hinge seat 214 is installed with a limiting roller 22.

[0050] In this embodiment, each side limiting assembly includes two limiting rollers 22, which can increase the width of the limit and improve the stability of the limit. And the limiting inclined rods 211 in each side limiting assembly are arranged in pairs and share the force together, which can increase the force-bearing capacity. The limiting inclined rod 211 is of an inclined structure. On the one hand, it can avoid interfering with the synchronous lifting device 17. On the other hand, the whole limiting bracket 21 is inclined downward, which can ensure that the limiting roller 22 is located within the support frame, realize the protection of the rotating parts, and can also improve the structural compactness of the device. The waist-shaped holes 213 on the limiting horizontal mounting plate 212 are beneficial to installation and facilitate adjusting the installation position according to the actual situation to ensure that the limiting roller 22 just abuts against the outer side wall of the injection molding barrel 15.

[0051] Please refer to Figure 7, according to the specific embodiments of the present invention, the top frame 16 includes a horizontal frame plate 161, an upper vertical frame plate 162, a first lower vertical frame plate 163 and a second lower vertical frame plate 164. The horizontal frame plate 161 is fixed to two adjacent side walls of the injection molding barrel 15 respectively. The upper vertical frame plate 162 is in the shape of a triangular plate. One right-angled side of the upper vertical frame plate 162 is fixed to the side of the injection molding barrel 15, and the other right-angled side of the upper vertical frame plate 162 is fixed to the upper plane of the horizontal frame plate 161. Both the first lower vertical frame plate 163 and the second lower vertical frame plate 164 are in the shape of triangular plates. One right-angled side of the first lower vertical frame plate 163 is fixed to the side wall of the injection molding barrel 15, and the other right-angled side of the first lower vertical frame plate 163 is fixed to the lower plane of the horizontal frame plate 161. One right-angled side of the second lower vertical frame plate 164 is fixed to the other side wall of the injection molding barrel 15, and the other right-angled side of the first lower vertical frame plate 163 is fixed to the lower plane of the horizontal frame plate 161.

[0052] In this embodiment, longitudinal force transmission plates (the upper vertical frame plate 162, the first lower vertical frame plate 163 and the second lower vertical frame plate 164) are evenly and staggeredly arranged on the upper and lower parts of the directly stressed horizontal frame plate 161, which is beneficial to evenly disperse the force of the ejector rod 1711 on the injection molding barrel 15. The stress effect of the top frame 16 and the injection molding barrel 15 is improved, which is beneficial to avoid the situation of local failure of components.

[0053] , according to the specific embodiments of the present invention, a pressure feeder mounting plate 23 is provided at the top of the injection molding barrel 15. One end of the pressure feeder mounting plate 23 is hinged to one side wall of the injection molding barrel 15, and the other end of the pressure feeder mounting plate 23 is movably clamped to the other opposite side wall of the injection molding barrel 15. The screw pressure feeder 20 is installed on the pressure feeder mounting plate 23.

[0054] In this embodiment, one end of the pressure feeder mounting plate 23 is hinged and the other end can be opened. During the use of the present invention, due to the high viscosity of the material, when the material adheres too thickly or is blocked during use, it is necessary to flush and clean the injection molding barrel 15. With the structure of this embodiment, it is convenient to load and open the screw pressure feeder 20, and the cleaning is more convenient and fast.

[0055] Please refer to Figures 7 - 8 , according to the specific embodiments of the present invention, the pressure feeder mounting plate 23 is hinged to the injection molding barrel 15 through a hinge joint 24. One end of the hinge joint 24 is fixed to the pressure feeder mounting plate 23, and the other end of the hinge joint 24 is fixed to the side wall of the injection molding barrel 15. The pressure feeder mounting plate 23 is movably clamped to the injection molding barrel 15 through a clamping joint 25. The clamping joint 25 includes a rod seat 251 and a rotating rod 252. The rod seat 251 is fixed to the injection molding barrel 15. One end of the rotating rod 252 is hinged to the rod seat 251, and a pressure plate 253 for pressing the pressure feeder mounting plate 23 is provided at one end of the rotating rod 252. The pressure plate 253 is in the shape of a disc.

[0056] The card connector 25 includes a clamped state and an open state. In the clamped state, the rotating rod 252 is in a vertical state, the pressure plate 253 presses against the mounting plate 23 of the blanking machine, and the mounting plate 23 of the blanking machine cannot be opened. In the open state, the rotating rod 252 is in a horizontal state, the pressure plate 253 is released, and the mounting plate 23 of the blanking machine can be opened around the hinge joint 24.

[0057] According to a specific embodiment of the present invention, the pumping input material assembly 19 is connected and includes: a hydraulic pump station 191, a mixer 192, a mixing discharge valve 193, a material transfer pump 194, and a hard pipeline for the material transfer pump 194 to send materials. The hydraulic pump station 191 is used to provide mixing power for the mixer 192. The mixer 192 is sequentially connected to the hose 18 through the mixing discharge valve 193, the material transfer pump 194, and the hard pipeline for the material transfer pump 194 to send materials.

[0058] In this embodiment, under the power of the hydraulic pump station 191, the mixer 192 rotates and mixes various materials including shield muck evenly. The mixed materials flow out through the mixing discharge valve 193 and enter the injection molding barrel 15 through the hard pipeline for the material transfer pump 194 to send materials and the hose 18 under the action of the material transfer pump 194, realizing continuous feeding.

[0059] According to a specific embodiment of the present invention, a position sensor for sensing the position of the injection molding barrel 15 is provided on the blanking support frame 14.

[0060] In this embodiment, by setting a plurality of position sensors, the position of the injection molding barrel 15 can be detected, which is beneficial to cooperate with the electrical control system to realize automatic control.

[0061] The following combines the attached Figures 10 - 13 To further illustrate the structure of the multi-channel injection valve 400 in the present invention.

[0062] Please refer to the attached Figures 10 - 12The multi-channel injection valve 400 includes: an upper discharge plate 01, an intermediate material dividing partition 02 and a lower discharge plate 03. The upper discharge plate 01 is provided with a plurality of upper discharge channels 011 arranged at intervals, and the lower discharge plate 03 is provided with a lower discharge channel 031 corresponding to each upper discharge channel 011. The intermediate material dividing partition 02 is provided with a feed channel 021 with the same number as the upper discharge channels 011; a sliding guide plate 04 is further provided between the upper discharge plate 01 and the lower discharge plate 03, and a guide groove 041 is provided on the sliding guide plate 04. The intermediate dividing partition 02 is arranged in the guide groove 041, and the intermediate dividing partition 02 is slidably connected to the sliding guide plate 04; the upper discharge plate 01, the sliding guide plate 04 and the lower discharge plate 03 are sequentially fitted from top to bottom, and the thickness of the intermediate dividing partition 02 is less than the thickness of the sliding guide plate 04; a linear telescopic power part 05 is connected to one side of the intermediate dividing partition 02, and the linear telescopic power part 05 is used to drive the intermediate dividing partition 02 to move back and forth along the guide groove 041 to realize the connection and closing between the upper discharge channel 011 and the lower discharge channel 031.

[0063] More specifically, the linear telescopic power member 05 is a telescopic oil cylinder or a telescopic air cylinder.

[0064] In this embodiment, the multi-channel injection valve 400 has an open state and a closed state. When the multi-channel injection valve 400 is in the open state, the upper discharge channel 011 is connected to the lower discharge channel 031 through the material channel 021. When the multi-channel injection valve 400 is in the closed state, the intermediate material dividing partition 02 blocks the communication between the upper discharge channel 011 and the lower discharge channel 031. Detailed description is as follows.

[0065] The linear telescopic power element 05 drives the middle material distribution partition 02 to move. When the feed channel 021 moves to a position aligned with the upper discharge channel 011, the upper discharge channel 011 and the lower discharge channel 031 are connected, and the multi-channel injection valve 400 is in the open state. When the feed channel 021 moves to a position where the feed channel 021 and the upper discharge channel 011 are offset, and the middle material distribution partition 02 blocks all upper discharge channels 011, the connection between the upper discharge channel 011 and the lower discharge channel 031 is blocked, and the multi-channel injection valve 400 is in the closed state.

[0066] According to a specific embodiment of the present invention, the upper discharge plate 01 is a rectangular plate, the shape of the lower discharge plate 03 is the same as that of the upper discharge plate 01, and the upper discharge plate 01 and the lower discharge plate 03 are aligned vertically.

[0067] More specifically, the upper discharge plate 01 is a square plate, and an upper connection hole 012 is provided at each corner of the upper discharge plate 01. A lower connection hole 032 is correspondingly provided at a position of the lower discharge plate 03 opposite to the upper discharge plate 01. A threaded connector passes through the upper connection hole 012 and the lower connection hole 032 at the same time to fix the upper discharge plate 01, the sliding guide plate 04, and the lower discharge plate 03 into one body.

[0068] In this embodiment, the rectangular structure is beneficial to forming and is also beneficial to matching the shape of the rectangular mold. By providing a threaded connector to form a detachable connection structure, it is beneficial to the disassembly, assembly, and replacement of the upper discharge plate 01, the sliding guide plate 04, and the lower discharge plate 03.

[0069] According to a specific embodiment of the present invention, the thickness of the middle material distribution partition 02 is 0.45 - 0.85 times the thickness of the sliding guide plate 04.

[0070] More specifically, the thickness of the middle material distribution partition 02 is 0.65 times the thickness of the sliding guide plate 04. With this structure, there is a gap between the middle material distribution partition 02 and the upper discharge plate 01, which can ensure the smooth reciprocating movement of the middle material distribution partition 02, but the amount of this gap is small to achieve the purpose of minimizing the thickness of the accumulated material layer on the upper part of the middle material distribution partition 02.

[0071] According to a specific embodiment of the present invention, the middle material distribution partition 02 is rectangular as a whole, the guide groove 041 is rectangular, and the width of the guide groove 041 matches the width of the middle material distribution partition 02.

[0072] According to a specific embodiment of the present invention, the arrangement mode of the material passing channel 021 is the same as the arrangement mode of the upper discharge channel 011, and the upper discharge channels 011 are arranged in a rectangular array, and the row spacing between adjacent upper discharge channels 011 is equal to the column spacing between adjacent upper discharge channels 011.

[0073] In this embodiment, with this structure, multi-column and multi-row discharging can be realized, and an equidistant matrix can be formed, which is beneficial to improving the uniformity of discharging.

[0074] According to a specific embodiment of the present invention, there are three columns and five rows of upper discharge channels 011 on the upper discharge plate 01; on the side of the upper discharge plate 01 away from the lower discharge plate 03, there is a recessed installation sealing groove 013, and all the upper discharge channels 011 are arranged within the area surrounded by the installation sealing groove 013.

[0075] With this structure, before injection, a pressure injection molding barrel 15 is first installed on the upper discharge plate 01, and the bottom of the feeding contacts the bottom of the installation sealing groove 013 to ensure the sealing between the pressure injection molding barrel 15 and the upper discharge plate 01. The material is injected through the pressure injection molding barrel 15, which can realize the pressurized injection of the material and also avoid the scattering of the material.

[0076] According to a specific embodiment of the present invention, the installation sealing groove 013 is rectangular ( Figure 10 and 11 as shown). On the side of the upper discharge plate 01 away from the lower discharge plate 03, a plurality of injection hood mounting holes 014 are further provided. The injection hood mounting holes 014 are all arranged outside the area surrounded by the installation sealing groove 013.

[0077] It should be noted that the installation sealing groove 013 can also be circular ( Figure 12 as shown). When the installation sealing groove 013 is circular, the lower part of the injection molding barrel 15 is circular and matches it, which is beneficial to the close fit between the injection molding barrel 15 and the upper discharge plate 01, improving the sealing performance and preventing material leakage.

[0078] In this embodiment, with this structure, the injection hood mounting holes 014 will not affect the injection of materials. The injection hood mounting holes 014 are used to fixedly install the injection molding barrel 15.

[0079] According to a specific embodiment of the present invention, the upper discharge channel 011 and the lower discharge channel 03 have the same shape.

[0080] In this embodiment, with this structure, when the upper discharge channel 011 and the lower discharge channel 031 are aligned, it is beneficial to form a sufficiently large material passing space to ensure that the material can pass through smoothly.

[0081] On the basis that the upper discharge channel 011 and the lower discharge channel 031 have the same shape, using different shapes of the upper discharge channel 011 is beneficial for the cooperation between the upper discharge channel 011 and the lower discharge channel 031 to control the parameters of materials with different fluidities passing through.

[0082] Next, the multi-channel injection valve 400 in the present invention will be further described.

[0083] During use, the multi-channel injection valve 400 in the present invention is arranged above the combined multi-cavity mold 300. Through the multi-channel injection valve 400 in the present invention, the plasticized material is injected into the mold. Specifically, when the cavities of the combined multi-cavity mold 300 are arranged in a matrix of three rows and five columns, the upper discharge channel 011 correspondingly has a matrix arrangement structure of three rows and five columns, and the lower discharge channel 031 has the same structure as the upper discharge channel 011. The shape and position of the material passing channel 021 correspond to those of the upper discharge channel 011.

[0084] During injection, the lower discharge plate 03 covers the top of the mold, and the upper discharge channel 011, the material passing channel 021, and the lower discharge channel 031 are aligned, that is, the orifices of the three coincide to form an injection channel. Each cavity corresponds to an injection channel, and the multi-channel injection valve 400 is in an open state.

[0085] After the injection is completed, the linear telescopic power member 05 drives the intermediate material distribution partition 02 to move outward until it just closes the through hole between the upper discharge plate 01 and the lower discharge plate 03 and then stops. At this time, the intermediate material distribution partition 02 shields all the upper discharge channels 011, and the multi-channel injection valve 400 is in the closed state, interrupting the injection.

[0086] Then, the gap between the lower discharge plate 03 and the top of the combined multi-unit mold 300 is opened to about 1 mm, and a slight pause is made (to facilitate the disconnection of the material adhered to the lower discharge plate 03 from the material in the mold cavity), and then the lower discharge plate 03 is completely separated from the mold.

[0087] By using the multi-channel injection valve 400 in the present invention, each cavity of the multi-cavity mold can be injected synchronously, realizing uniform multi-channel injection of the fluidized plastic material, which is beneficial to quickly and effectively filling each cavity, and can greatly improve the injection efficiency. In addition, the opening and closing of all injection channels can be controlled simultaneously and quickly.

[0088] The multi-channel injection valve 400 in the present invention is mainly used in the molding process section during the resource utilization of shield muck, and is used in cooperation with a mold for casting and molding building materials products. By using the matrix multi-channel discharge port 151 and utilizing the dislocation structure, the opening and closing of the injection channels are realized. This valve can realize the rapid and uniform injection of fluidized plastic materials into the cavities of the multi-unit mold.

[0089] According to the specific embodiment of the present invention, the upper discharge channel 011 is composed of a plurality of first rectangular holes 011a arranged at intervals.

[0090] It should be noted that the multi-channel injection valve 400 in the present invention can also be of other structures. Please refer to Figure 13 , a multi-channel injection valve 400, including: an upper discharge plate (multi-column strip channels) 01b, an intermediate material distribution partition 02, and a lower discharge plate (multi-column strip channels) 03b. This multi-channel injection valve 400 is Figure 12 basically the same as the structure of the multi-channel injection valve 400 in

[0091] Figure 12 In Figure 13 In

[0092] The upper discharge channel 011 is composed of a plurality of first rectangular holes 011a arranged at intervals.

[0093] For the flowable plastic materials with good fluidity, it is advisable to adopt a structure in which the discharge channel is composed of a plurality of first rectangular holes 011a arranged at intervals ( Figure 12 the upper feed channel in

[0094] is in the form of multiple columns of strips), and each discharge channel discharges materials in the form of multiple columns of strips to control the flow rate and ensure that the amount of materials in the mold will not get out of control. Figure 13 For the flowable plastic materials with high viscosity and poor fluidity, it is advisable to adopt a structure in which the upper discharge channel 011 is a second rectangular hole 011b (

[0095] the upper feed channel in

[0096] is in the shape of a single-port rectangle), to ensure the consistency and uniformity of the material flow rate per unit time in each channel. Figures 20 - 23 As can be seen from the above, the multi-channel injection valve 400 in the present invention has the advantages of simple structure, reliable operation, strong interchangeability, convenient disassembly and assembly, and simple operation. According to the usage requirements, the structures of the upper discharge plate 01 and the lower discharge plate 03 can be flexibly selected to complete the multi-cavity casting molding of the flowable plastic materials.

[0097] The finishing device includes a first scraper assembly 100, a water spray and lubrication assembly, and a second scraper assembly 200 that are arranged in parallel and at intervals in sequence. The structures of the first scraper assembly 100 and the second scraper assembly 200 are the same; the first scraper assembly 100 includes a scraper shaft 001 and a scraper body 002 provided on one side of the scraper shaft 001. The scraper body 002 is rotatably connected to the scraper shaft 001, and the scraper body 002 is also connected to the scraper shaft 001 through a torsion spring assembly. The torsion spring assembly includes a torsion spring block and a torsion spring body 003. The torsion spring body 003 is sleeved on the scraper shaft 001. The torsion spring block includes a fixed plate 004 and a stop rod 005 that are connected. The fixed plate 004 is installed on the scraper shaft 001, and the stop rod 005 is located on one side of the fixed plate 004. One extended end of the torsion spring body 003 is inserted into the stop rod 005; the other extended end of the torsion spring body 003 abuts against the scraper body 002 to provide pressure to the scraper body 002; the water spray and lubrication assembly includes a spray rod 006 and a plurality of nozzles 007 arranged at intervals on the spray rod 006.

[0098] The finishing device is used to perform continuous surface finishing after injecting viscous mixed materials with a fluidized form into a viscous material injection molding die (a combined multi - unit die 300) by pouring. The first scraper assembly 100 and the second scraper assembly 200 form two consecutive scraping and finishing processes. The first scraper assembly 100 is mainly used to scrape the materials above the combined multi - unit die 300 flat. The water spray component is used to spray water mist to moisten the upper surface of the building product after the first scraping. Then, the second scraper assembly 200 performs secondary scraping, which can level the upper surface of the building product to achieve a finishing effect. Therefore, by using this finishing device, the scraping and finishing operations of the building product can be continuously carried out, effectively improving the smoothness and flatness of the upper surface of the building product and enhancing the surface quality of the building product.

[0099] According to a specific embodiment of the present invention, the first scraper assembly 100 includes two sleeves 008. The two sleeves 008 are respectively fixed at both ends of the scraper body 002, and the rotation connection between the scraper body 002 and the scraper shaft 001 is realized by sleeving the sleeves 008 on the scraper shaft 001.

[0100] In this embodiment, the sleeve 008 is circular - ring - shaped, and the scraper shaft 001 is cylindrical as a whole. This structure is used to form a simple and reliable hinge structure. When the scraper body 002 drives the sleeve 008 to rotate, the contact surface between the sleeve 008 and the scraper shaft 001 is a plane, with good wear resistance and stability. After scraping the materials repeatedly for many times, the reliability of the action can still be ensured.

[0101] According to a specific embodiment of the present invention, the torsion spring assemblies are two sets arranged at intervals.

[0102] In this embodiment, one set of torsion spring assemblies is respectively arranged at both ends of each scraper assembly, which can apply pressure to the scraper body 002 from both ends of the scraper body 002. The two pressures are superimposed to form a greater pressure to ensure the scraping effect. And with the structure of applying force at both ends, the stability is better.

[0103] According to a specific embodiment of the present invention, the two sleeves 008 are arranged between the two torsion spring assemblies.

[0104] In this embodiment, during assembly, when the scraper shaft 001 and the sleeve 008 are free, first, the sleeve 008 is sleeved to form a structure in which the sleeve 008 is rotationally connected to the scraper shaft 001, and then the torsion spring assembly is installed. This structure is conducive to the assembly and disassembly of the device.

[0105] According to a specific embodiment of the present invention, the scraper body 002 is inclined and installed on one side of the scraper shaft 001, and the nozzle 007 is inclined and installed, and the inclination direction of the nozzle 007 is the same as the inclination direction of the scraper body 002.

[0106] More specifically, the squeegee body 002 includes a scraping state. When the squeegee body 002 is in the scraping state, the angle between the squeegee body 002 and the horizontal plane is 25° to 45°.

[0107] In this embodiment, both squeegee bodies 002 are inclinedly installed, and this structure is conducive to scraping the material. The inclination direction of the nozzle 007 is the same as that of the squeegee body 002. This structure is conducive to the nozzle 007 spraying water towards the rear end in the scraping direction, without affecting the scraping of the previous squeegee body 002, and part of the water mist sprayed by the nozzle is dispersed in the squeegee body 002 of the second squeegee assembly 200, which can prevent the second squeegee body 002 from sticking to the material and can further improve the finishing effect.

[0108] Please refer to Figure 23 According to the specific embodiment of the present invention, a block mounting hole 009 penetrating through it is provided on the fixing plate 004. The squeegee shaft 001 penetrates through the block mounting hole 009. A strip-shaped card slot 010 penetrating through it is provided on the blocking rod 005. One end of the strip-shaped card slot 010 is open, and one protruding end of the torsion spring body 003 is inserted into the strip-shaped card slot 010.

[0109] In this embodiment, the structure of the block mounting hole 009 is adopted, which is conducive to quickly sleeving the fixing plate 004 on the squeegee shaft 001. One protruding end of the torsion spring body 003 is pushed into the strip-shaped card slot 010 from the open end of the strip-shaped card slot 010, and the protruding end of the torsion spring body 003 is clamped by the strip-shaped card slot 010.

[0110] More specifically, a block anti-rotation plane (not shown in the figure) is provided on the inner wall of the block mounting hole 009, and a shaft anti-rotation plane is provided at the position of the squeegee shaft 001 corresponding to the block anti-rotation plane. With this structure, it is convenient for the quick installation of the torsion spring block and can prevent relative rotation between the torsion spring block and the squeegee shaft 001, ensuring the stability of the connection between the protruding end of the torsion spring body 003 and the blocking rod 005.

[0111] According to the specific embodiment of the present invention, a rectangular avoidance notch 0110 formed by depression is provided on one side of the squeegee body 002 close to the torsion spring body 003.

[0112] In this embodiment, the rectangular avoidance notch 0110 is used to provide necessary space for the installation of the torsion spring body 003 to avoid interference.

[0113] According to the specific embodiment of the present invention, the finishing device is arranged above the viscous material injection molding die. The viscous material injection molding die includes product molding cavities 5 distributed in a rectangular array. A slag collection box 4 is provided on one side of the product molding cavity 5, and a material collection port is provided at the top of the slag collection box 4.

[0114] In this embodiment, a slag collecting box 4 is arranged at the position where the scraping ends, which can ensure that the waste scraped by the scraping plate main body 002 directly falls into the slag collecting box 4, facilitating the cleaning of the waste slag on the site. More specifically, when the scraping plate main body 002 is in the scraping state, the lower part of the scraping plate main body 002 fits with the upper surface of the viscous material injection molding die, and the height of the material collecting port is lower than the height of the upper surface of the viscous material injection molding die. In this embodiment, with this structure, the excess material scraped off falls directly into the slag collecting box 4 from the upper surface of the die through the material collecting port, ensuring the material collection effect.

[0115] The following will further describe the combined multi - die 300 in the present invention with reference to the attached Figures 14 - 19 drawings.

[0116] Please refer specifically to Figures 14 - 16 , the combined multi - die 300 includes: a die main body 1, a bottom support plate 2, and a slag collecting box 4. The die main body 1 is provided with a plurality of cavities 12 penetrating through it in the up - down direction. The bottom support plate 2 is used to simultaneously close the lower openings of the plurality of cavities 12, thereby forming a plurality of independent product forming cavities 5. The die main body 1 and the bottom support plate 2 are detachably connected, and the slag collecting box 4 is located at the side of the die main body 1.

[0117] It should be noted that the "up - down direction" in the present invention refers to the height direction of the die main body 1. In this embodiment, the detachable connection between the die main body 1 and the bottom support plate 2 can be achieved through a connecting member. The connecting member can be a buckle or a compression bolt 3. When the connecting member is locked, the bottom support plate 2 is fixed to the lower part of the die main body 1 to form a product forming cavity 5 for pouring viscous materials, and the slag collecting box 4 is movably arranged at the side of the die main body 1 for centrally collecting excess materials.

[0118] Please refer specifically to Figure 19, during use, first use a connecting piece to fix the bottom support plate 2 to the lower part of the mold body 1, and assemble the combined multi-cavity mold 300 in the present invention. Then place the combined multi-cavity mold 300 in the present invention as a whole on the conveying platform 30, and ensure that the slag collection box 4 is located at the trailing end. After the product forming cavity 5 is filled with materials, level the surface, and use the slag collection box 4 to collect the scraped materials. After the adhesive in the mold solidifies and undergoes a period of curing, the mold body 1 can be removed from the bottom support plate 2. Under the vertical external force from top to bottom, the building materials products can be quickly taken out from the mold body 1. In this way, all the building materials products can be separated from the mold body 1 at one time, with high demolding efficiency. And because when applying force, the side walls of the building materials products are protected by the mold cavity 12, therefore, the situation that the side wall surface of the building materials products is peeled off and affects the shape of the building materials products will not occur, which can effectively guarantee the quality of the building materials products. And the overall demolding time is short and the efficiency is high. The combined multi-cavity mold 300 in the present invention is a modular structure as a whole, and the main components are the mold body 1, the bottom support plate 2 and the slag collection box 4. Each component is an integral structure, and the overall stability is good.

[0119] Therefore, compared with the prior art, using the combined multi-cavity mold 300 in the present invention to form building products can form multiple products at one time, and the product quality is high. The waste generated during the forming process is centrally collected and is easy to clean. The combined multi-cavity mold 300 in the present invention is used for building products that solidify viscous materials into various geometric-shaped products, and also has the advantages of simple structure and easy disassembly and assembly. During use, the structure of the mold cavity 12 can be reasonably set according to needs to form building products with different shapes.

[0120] According to the specific embodiment of the present invention, the mold body 1 is rectangular as a whole. Connecting ear plates are fixedly arranged on the outer side of the mold body 1. Ear plate connection holes 9 are arranged on the connecting ear plates. The bottom support plate 2 is provided with support plate connection holes corresponding to the positions of the ear plate connection holes 9. The mold body 1 and the bottom support plate 2 are detachably connected by passing a compression bolt 3 through the ear plate connection holes 9 and extending into the support plate connection holes. In this embodiment, the connecting ear plates have two functions. One is that the connecting ear plates are used to process the ear plate connection holes 9, which is convenient for installing the compression bolts 3 to realize pressing and fixing the mold body 1 on the bottom support plate 2, ensuring that the two are closely attached, preventing material leakage, and improving product accuracy. The other is that the connecting ear plates can be used as the force application points during the transfer of the mold body 1, improving the convenience of use.

[0121] According to a specific embodiment of the present invention, the slag collecting box 4 is rectangular as a whole, and a side wall in the length direction of the slag collecting box 4 abuts against a side wall of the mold body 1; the connecting ear plates include a first ear plate 6, a second ear plate 7, and a third ear plate 8 that successively surround the other three side walls of the mold body 1, and ear plate connection holes 9 are respectively provided on the first ear plate 6, the second ear plate 7, and the third ear plate 8. In this embodiment, the connecting ear plates are arranged on three consecutive side walls of the mold body 1, and the pressing bolts 3 can be installed from three sides of the mold body 1 to press the mold body 1, further ensuring the tightness of the fit between the mold body 1 and the bottom support plate 2. One empty side wall is reserved to facilitate the slag collecting box 4 to closely lean against this side of the mold body 1, so that when scraping, the excess material will not fall from the gap between the mold body 1 and the slag collecting box 4.

[0122] According to a specific embodiment of the present invention, more than two ear plate connection holes 9 are respectively provided on the first ear plate 6, the second ear plate 7, and the third ear plate 8. More specifically, two ear plate connection holes 9 are respectively provided on the first ear plate 6, the second ear plate 7, and the third ear plate 8; the lower end surface of the connecting ear plate is flush with the lower end surface of the mold body 1. In this embodiment, after adopting this structure, 6 pressing bolts 3 are correspondingly provided. During operation, the mold body 1 is placed on the upper plane of the bottom support plate 2, and the two are closely fitted through 6 pressing bolts 3. Subsequently, the slag collecting box 4 is clamped between the mold body 1 and the limit rib plate 10, and it is ensured that the height of the slag collecting box 4 is lower than that of the mold body 1. The assembly of the combined multi-station mold 300 is completed.

[0123] According to a specific embodiment of the present invention, a limiting member is fixedly provided on the bottom support plate 2, the slag collecting box 4 is arranged on the bottom support plate 2, and the slag collecting box 4 is arranged between the mold body 1 and the limiting member. In this embodiment, the limiting member is used to limit the slag collecting box 4, which can prevent the slag collecting box 4 from moving during use and also facilitate the accurate loading of the slag collecting box 4.

[0124] According to a specific embodiment of the present invention, the height of the top of the slag collecting box 4 is less than the height of the top of the mold body 1. In this embodiment, by adopting this structure, the excess waste scraped out by the subsequent finishing system can be effectively collected.

[0125] According to a specific embodiment of the present invention, the limiting member includes two spaced-apart limit rib plates 10. The limit rib plates 10 are trapezoidal plates or triangular plates as a whole, and the two limit rib plates 10 are respectively welded and fixed to the bottom support plate 2. In this embodiment, two limit rib plates 10 are adopted to achieve limiting at two positions. While ensuring the limiting effect, the structure can be simplified, and at the same time, the contact area between the limit rib plate 10 and the slag collecting box 4 can be reduced, which is beneficial to the loading and removal of the slag collecting box 4.

[0126] According to the specific embodiments of the present invention, reinforcing rib plates 11 are further provided on the outer side of the mold body 1, and the reinforcing rib plates 11 are respectively welded to the mold body 1 and the connecting ear plates. In this embodiment, the reinforcing rib plates 11 are used to improve the overall strength of the mold body 1.

[0127] Please refer to Figure 18 , according to the specific embodiments of the present invention, the entire cavity 12 is rectangular, and a plurality of cavities 12 are arranged in a rectangular array. In the length direction of the slag collecting box 4, the distance between two adjacent cavities 12 is A; in the width direction of the slag collecting box 4, the distance between two adjacent cavities 12 is B; A > B. In this embodiment, with this structure, a plurality of building products arranged in a rectangular array can be formed at one time, and the distance between adjacent building products is minimized as much as possible. At the same time, sufficient distance can be ensured between the building products in adjacent columns, which is beneficial to ventilation and transportation.

[0128] Please refer to Figure 17 , according to the specific embodiments of the present invention, a plurality of recessed weight-reducing blind holes 13 are provided on one side of the mold body 1 close to the bottom support plate 2. The weight-reducing blind holes 13 are rectangular holes, and the weight-reducing blind holes 13 are provided between two cavities 12 along the length direction of the slag collecting box 4. In this embodiment, the weight-reducing blind holes 13 are blind hole structures. With this structure, the thick parts are hollowed out, which is beneficial to reducing the weight of the mold body 1. The combined multi-cavity mold 300 in the present invention is used for the injection molding and rapid demolding of viscous materials. It adopts a split combination method, can quickly pour building materials products, and can also realize the rapid separation of the products from the mold.

[0129] The present invention is designed for the technical problem that the viscous muck material is sticky after being mixed with the admixture and needs to be quickly formed. The viscous material after being mixed by the compound mixing equipment will enter the molding machine hopper through the hard pipe pipeline and the vibration isolation hose 18 pipeline via the pumping device, and the material will be injected into the combined multi-cavity mold 300 via the matrix multi-channel discharge valve by the servo-screw feeding device. According to the different flow characteristics of the materials and the requirements for the final shape of the formed products, the multi-channel discharge valves with different structures can be replaced as a whole to obtain the required geometric shape of the discharge valve orifice. By using the cooperation of the molding machine hopper and the multi-channel discharge valve, a single-cavity multi-channel injection feeding structure is formed, which is used to quickly form the viscous material. During injection, different injection times are set according to the viscosity of the material to ensure that the surface of the multi-cavity mold is smooth and the on-site secondary waste is extremely small.

[0130] The present invention adopts a multi-channel injection method for multi-connected die injection molding of viscous materials, and is a key device for the resource utilization of shield muck. The present invention includes two sets of servo power systems, upper and lower. The upper servo power system is a component of the screw feeder 20 and is used to drive the injection and pressing piston plate in the screw feeder 20 to move up and down. The lower servo power system is the power of the synchronous lifting device 17 and is used to drive the injection molding barrel 15 to move up and down. The multi-channel injection valve 400 adopts a matrix multi-channel staggered discharge valve port, and different structures of the multi-channel injection valve 400 can be adopted according to the material properties and the geometric shape of the building products to be molded (specifically, the outlet shape and the distance between the outlets of the multi-channel injection valve 400 can be changed). By using the multi-channel injection molding system for viscous materials of the present invention, injection operations can be realized, the quality of the products is uniform, and energy conservation and high efficiency can be achieved.

[0131] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. It can be the communication inside two components, or a "transmission connection", that is, power connection is carried out through various suitable methods such as belt drive, gear drive or sprocket drive. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
