Description

Technical Field

[0001] The invention relates to the technical field of foaming and casting, in particular to full-automatic batching and heat-insulating foaming and casting equipment. Background Art

[0002] Foam molding is a general term for the molding methods of making foam plastic materials. The foamed materials made by this process are widely used in aviation, building materials, automotive parts, electronic products and other fields. The bubble molding process is to first dissolve the gas in the liquid polymer or heat the polymer to a molten state, while generating gas and forming a saturated solution, and then forming countless tiny bubble nuclei through nucleation. In this process, the three steps of batching, insulation foaming and casting are the most important. In existing equipment, the three steps are often separated and need to be completed step by step. The cumbersome steps lead to reduced work efficiency and increased workload, and increased manpower and equipment costs.

[0003] The existing patent with authorization announcement number CN207607032U discloses an automatic polyurethane foam material dispensing machine, including a frame, a first dispensing barrel and a second dispensing barrel. The bottom end of the frame is provided with moving wheels, the upper end of the frame is provided with a support panel, the upper end of the precision pump motor mounting support plate is provided with a first precision metering pump, and the upper end of the precision pump motor mounting support plate is provided with a second precision metering pump at a side position close to the first precision metering pump. A high-speed mixing motor, a first precision metering pump and a second precision metering pump are provided to ensure that materials are accurately distributed and that the hardness of the products is consistent. A high-speed injection gun is provided, which is easy to operate and maintain and saves time. Temperature sensors are provided at both ends of the temperature control box to keep the internal materials of the first dispensing barrel and the second dispensing barrel at a certain temperature through the temperature control box, thereby better shortening the foaming molding time and improving work efficiency.

[0004] However, since the above patent solution cannot remove the mother liquid remaining on the nozzle, it is easy to agglomerate and clog the nozzle. At the same time, it is impossible to judge intuitively and promptly after the casting is completed. Continuing casting will cause leakage between the nozzle and the casting port. At the same time, it is difficult to position the nozzle and the casting port during casting, resulting in the nozzle angle being tilted and unable to spray evenly inside the mold, causing some areas to foam quickly and some areas to fail to foam and agglomerate, ultimately resulting in quality defects in the finished foamed material.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figure 1-Figure 8 , which is the first embodiment of the present invention, provides a fully automatic batching, thermal insulation, foaming and casting equipment, including a foaming molding mechanism, a material changing mechanism 200 and a positioning mechanism 300. The batching, thermal insulation, foaming and casting are realized by the foaming molding mechanism, and the floating ball 105b and the nozzle 105 are fitted to scrape off the excess foaming material mother liquid to prevent agglomeration and facilitate continuous casting. The switch rod 105a and the block 303 are used to realize positioning and anti-loosening to prevent leakage of the mother liquid.

[0037] Specifically, the fully automatic batching insulation foaming casting equipment includes:

[0038] The foaming molding mechanism comprises a shell 101, a batching component 102 and a heat-insulating foaming component 103 which are both arranged on the upper end surface of the shell 101, a casting frame 104 which is movably arranged inside the shell 101, and a nozzle 105 which is arranged on the inner wall of the shell 101. The batching component 102 is connected with the heat-insulating foaming component 103, the heat-insulating foaming component 103 is connected with the nozzle 105, the nozzle 105 is movably engaged with the casting frame 104, the casting frame 104 comprises a moving platform 104a which is slidably arranged on the bottom of the inner wall of the shell 101 and a mold 104b which is arranged on the upper end surface of the moving platform 104a, and the raw materials enter the heat-insulating foaming component 103 through the batching component 102 to generate a foaming mother liquid;

[0039] The material changing mechanism 200 includes a reversing column 201 and a wave cylinder 202 disposed on the lower end surface of the reversing column 201;

[0040] The positioning mechanism 300 includes a discharge head 301 slidably disposed in the nozzle 105 , an injection port 302 disposed on the mold 104 b and a clamping block 303 disposed in the discharge head 301 . The clamping block 303 engages with the discharge head 301 when foaming mother liquid flows in the discharge head 301 .

[0041] More preferably, the batching component 102 can mix various raw materials according to a predetermined ratio, monitor the material quality and flow rate through sensors, and allocate the raw materials according to the preset ratio. The thermal insulation foaming component 103 heats or freezes the mixture and injects gas at the same time to form a foaming material mother liquid with good performance and stable structure in the closed cavity.

[0042] Furthermore, the nozzle 105 pumps the adjusted mother liquor into the injection port 302 through a gas pressure pump, enters the preset mold 104b, and performs subsequent heat preservation on the casting frame 104. The casting frame 104 is arrayed with 6 molds 104b. The mold 104b is a product mold to be produced and has an insulation layer. The casting frame 104 can slide out of the shell 101 to perform a subsequent insulation process on the foaming material mother liquor. At the same time, the casting frame 104 leads the new mold 104b into the shell 101 to continue casting.

[0043] Among them, in this embodiment, the batching component 102 is two storage tanks, the shell 101 is a hollow rectangular shell, the thermal insulation foaming component 103 is a sealed cavity with a heating and cooling module, the raw material passes through the batching component 102 and enters the thermal insulation foaming component 103 and is finally injected into the mold 104b through the nozzle 105, the casting frame 104 has an insulation module and can slide in the shell 101, so that the foaming material mother liquid completes the entire foaming process at a preset temperature.

[0044] Preferably, a positioning frame 104c is provided on the casting frame 104, a positioning rod 104d is provided on the outer wall of the positioning frame 104c, a tank body 204 is movably sleeved on the outer wall of the corrugated cylinder 202, and a conveying pipe 204a is provided on the upper end surface of the tank body 204.

[0045] Preferably, a sleeve 204b is provided at the center of the upper end surface of the tank body 204, a pressing cylinder 201a is sleeved on the outer wall of the reversing column 201, a wedge-shaped groove 201a-4 is provided on the upper end surface of the pressing cylinder 201a, and a trapezoidal block 104d-1 is provided at one end of the positioning rod 104d.

[0046] Among them, the wedge-shaped groove 201a-4 is a trapezoidal groove with a chamfered bottom edge, and the triangular block 104d-1 is a right-angled trapezoid, and its inclined surface slides and fits with the chamfered surface of the wedge-shaped groove 201a-4, so that when the triangular block 104d-1 slides along the chamfered surface, it squeezes the pressing cylinder 201a downward and drives the reversing column 201 to move downward.

[0047] Among them, the tank body 204 is a sealed tank body, and the upper end of the nozzle 105 slides through the lower bottom surface of the tank body 204. The foaming liquid enters each nozzle 105 from the tank body 204 at the same time, thereby ensuring that the temperature and composition of the foaming mother liquid entering each mold 104b are consistent, meeting the requirements of mass production.

[0048] Furthermore, heating wires are provided on the inner and outer walls of the wave cylinder 202 at the other end of the reversing column 201 to prevent the pre-cooling and agglomeration of the foaming material mother liquid after entering the tank body 204, causing blockage or the temperature reduction causing the foaming effect to deteriorate. By adjusting the heating temperature of each heating wire of the wave cylinder 202, the temperature of each area changes, so that the optimal temperature for foaming of the mold 104b can be verified.

[0049] Furthermore, a switch rod 105a is slidably provided in the nozzle 105, and a slide groove 105a-1 is provided at one end of the switch rod 105a that slides out of the nozzle 105, and the lower end surface of the wave cylinder 202 is embedded in the slide groove 105a-1.

[0050] Preferably, a groove 302 a is formed on the inner wall of the injection port 302 , the block 303 is engaged with the groove 302 a , and a floating ball 105 b is slidably disposed in the nozzle 105 .

[0051] In this embodiment, a float 105b is provided at one end of the switch rod 105a that slides downward out of the nozzle 105, and the other end of the switch rod 105a is engaged and connected with the discharge head 301. The clamping block 303 is rotatably arranged on the outer wall of the switch rod 105a and slides through the nozzle 105. When the switch rod 105a moves downward, it pushes each clamping block 303 to rotate and slide into the clamping groove 302a, thereby achieving positioning and preventing the foaming material mother liquid from overflowing from between the nozzle 105 and the injection port 302.

[0052] More preferably, the float 105b is a hollow float. Initially, the foaming material mother liquid is sprayed from the nozzle 105 and sprayed onto the surface of the float 105b, and finally flows downward along various angles of the surface of the float 105b to various directions of the mold 104b.

[0053] Furthermore, when the shape of the mold 104b is square, the shapes and directions of the nozzle 105 and the float 105b are adapted thereto to achieve uniform flow diversion to various areas inside the mold 104b, so that the material in the mold 104b is evenly distributed, and excessive local foaming material is prevented from causing bubbles to be unable to volatilize and agglomerate, thereby affecting product quality. When the mold 104b is filled, the float 105b is lifted upward and blocks the nozzle 105. At the same time, the excess foaming material mother liquid is scraped off through mutual friction, thereby preventing the residual foaming material on the nozzle 105 from agglomerating and clogging, making it difficult to clean.

[0054] In summary, when in use, the required raw materials are first placed in the batching component 102, various raw materials are mixed according to a predetermined ratio, and then enter the heat-insulating foaming component 103 for heating, cooling and inflation to form a foaming material mother liquid, and enter the tank body 204 through the conveying pipe 204a, and are heated by the electric heating wire of the corrugated cylinder 202 to prevent agglomeration, and then injected into the mold 104b along the nozzle 105, and kept warm in the casting frame 104.

[0055] At the same time, when the new casting frame 104 slides along the shell 101 and the positioning rod 104d on the positioning frame 104c is inserted into the wedge-shaped groove 201a-4, it is proved that the position of the casting frame 104 has been aligned with the nozzle 105. At this time, the trapezoidal block 104d-1 and the wedge-shaped groove 201a-4 slide relative to each other, thereby pushing the pressing cylinder 201a to slide downward, and at the same time, the switch rod 105a is pressed downward by the wave cylinder 202, and the floating ball 105b slides out of the nozzle 105. At this time, the foaming material mother liquid can flow into the injection port 302 and be sprayed onto the floating ball 10 5b then flows to all directions of the mold 104b. At the same time, the high-pressure flow injection will push the float 105b to continue downward, driving the block 303 to rotate and engage into the slot 302a, completing the positioning and locking of the nozzle 105 and the mold 104b. When the injection is completed, the float 105b slowly rises and gradually blocks the nozzle 105, causing the block 303 to break away from the slot 302a, and finally automatically stops the injection. At the same time, the float 105b scrapes against the inner wall of the nozzle 105 to scrape off excess foaming material mother liquid, preventing agglomerations from clogging the nozzle 105 and affecting the next injection and casting.

[0056] Example 2

[0057] Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the wave cylinder 202 drives the nozzle 105 to open and close by rotating, and at the same time, the mother liquid of the foaming material in the tank body 204 is always kept at a set temperature by heating the wire and rotating, and regional agglomeration is prevented from causing blockage by stirring, and excess bubbles are discharged to ensure the quality of foaming casting.

[0058] Specifically, the pressure cylinder 201a is slidably sleeved on one end of the outer wall of the reversing column 201 and is fixed with an upper serrated ring 201a-1. The outer wall of the reversing column 201 is also fixed with a lower serrated ring 201a-2. The upper serrated ring 201a-1 and the lower serrated ring 201a-2 are movably engaged.

[0059] The outer wall of the lower serrated ring 201a-2 is provided with a shift groove 201a-3, and the inner wall of the sleeve 204b is provided with a limit bar 204b-1. The limit bar 204b-1 is slidably arranged on the upper serrated ring 201a-1 and movably engaged with the shift groove 201a-3.

[0060] One end of the upper sawtooth ring 201a-1 and the lower sawtooth ring 201a-2 are both provided with oblique teeth 201a-5, and the oblique teeth 201a-5 include an oblique side and a right-angle side.

[0061] More preferably, the bevel teeth 201a-5 of the upper serrated ring 201a-1 and the lower serrated ring 201a-2 can be interlocked and staggered in the initial state, and the right-angled side of the upper serrated ring 201a-1 is aligned with the beveled side of the lower serrated ring 201a-2, so that when the upper serrated ring 201a-1 contacts and presses down with the lower serrated ring 201a-2, the lower serrated ring 201a-2 tends to rotate toward the right-angled side as the reversing column 201 moves downward.

[0062] There are 6 shift grooves 201a-3 in total and are arranged in a circular array on the outer wall of the serrated ring 201a-2. The limit strip 204b-1 is a long strip-shaped block, which is embedded with the upper serrated ring 201a-1 and the shift groove 201a-3 at the same time in the initial state.

[0063] More preferably, a limit ring 204b - 2 is rotatably provided on the inner wall of the sleeve 204b , a first elastic member 204b - 3 is provided between the lower serrated ring 201a - 2 and the limit ring 204b - 2 , and the reversing column 201 slides through the limit ring 204b - 2 and extends to the inside of the tank body 204 .

[0064] Furthermore, the first elastic member 204b-3 is a spring and is sleeved on the outer wall of the reversing column 201. The outer wall of the wave cylinder 202 is provided with an arc groove in a circumferential array. The lower end surface of the wave cylinder 202 forms a wave-shaped slideway, and the lower end surface of the wave cylinder 202 is slidably arranged in the slide groove 105a-1.

[0065] In summary, when in use, as the casting frame 104 moves into the housing 101, the positioning frame 104c drives the positioning rod 104d to enter the wedge-shaped groove 201a-4, thereby pushing the pressing cylinder 201a to move downward, and the right-angled side of the upper sawtooth ring 201a-1 at the end of the pressing cylinder 201a fits with the oblique side of the lower sawtooth ring 201a-2. At the same time, since the two are simultaneously engaged with the limit strip 204b-1, the two cannot rotate. As the pressing cylinder 201a continues to be pressed downward, the lower sawtooth ring 201a-2 When the right-angled side of 01a-2 is lower than the lowest point of the limit bar 204b-1, the limit bar 204b-1 disengages from the shift groove 201a-3, and the lower serrated ring 201a-2 slides along the hypotenuse of the upper serrated ring 201a-1. At the same time, the limit bar 204b-1 slides from the right-angled side to the hypotenuse along the lower serrated ring 201a-2 and enters the next shift groove 201a-3 to continue to engage, so that the lower serrated ring 201a-2 rotates relative to the upper serrated ring 201a-1.

[0066] At the same time, the lower serrated ring 201a-2 slides downward while compressing the first elastic member 204b-3. After the lower serrated ring 201a-2 rotates to the next shift groove 201a-3, the first elastic member 204b-3 is reset, and the wave cylinder 202 moves up and down slightly and rotates at the same time. The switch rod 105a slides along the wave cylinder 202 through the slide groove 105a-1, so that the switch rod 105a moves up and down to realize the extension and retraction of the discharge head 301. At the same time, the wave cylinder 202 can also stir and heat the mother liquid of the foaming material in the tank body 204 to prevent agglomeration and remove excess bubbles.

[0067] Example 3

[0068] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that positioning and leak prevention are achieved by the float 105b being flushed and moved by the foaming material mother liquid. After the casting is completed, the float 105b rises to achieve automatic closing of the nozzle 105. At the same time, the excess foaming material mother liquid can be scraped away by the relative sliding of the float 105b and the nozzle 105 to prevent the nozzle 105 from agglomerating after being pulled out.

[0069] Specifically, a piston 105 c is slidably provided in the nozzle 105 , the piston 105 c is sleeved on the outer wall of the switch rod 105 a , and a second elastic member 105 c - 1 is provided between the upper end surface of the piston 105 c and the inner wall of the nozzle 105 .

[0070] Among them, the second elastic member 105c-1 is a spring, which drives the piston 105c to move upward in the initial state. The piston 105c is in the shape of a truncated cone with a larger bottom and a smaller top. The nozzle 105 has a truncated cone section that is narrow at the top and wide at the bottom. Driven by the second elastic member 105c-1, the piston 105c is movably engaged with the inner wall of the nozzle 105, thereby sealing the nozzle 105 to prevent the mother liquid of the foaming material from flowing back.

[0071] Furthermore, a connecting rod 304 is provided between the discharge head 301 and the piston 105 c , a lifting rod 304 a is slidably provided inside the connecting rod 304 , and a third elastic member 304 a - 1 is provided between the lifting rod 304 a and the connecting rod 304 .

[0072] The block 303 is rotatably disposed on the outer wall of the lifting rod 304 a , and the third elastic member 304 a - 1 is a spring. The spring overcomes the gravity of the lifting rod 304 a and always pulls the lifting rod 304 a close to the connecting rod 304 .

[0073] In summary, when the switch rod 105a descends, it drives the piston 105c to disengage from the nozzle 105, the nozzle 105 is connected, the discharge head 301 is physically fitted with the injection port 302, and when the foaming material mother liquid flows along the nozzle 105 and the discharge head 301 and is sprayed onto the upper end surface of the float 105b, the float 105b is sprayed downward by the foaming material mother liquid and drives the lifting rod 304a to overcome the spring force and descend. When the lifting rod 304a descends, it drives the block 303 to swing upward and engage with the slot 302a. The greater the injection flow rate and the greater the pressure of the mother liquid, the greater the positioning locking force, which prevents the nozzle 105 from falling off by itself, thereby positioning the discharge head 301 to the inside of the injection port 302 and preventing the foaming material mother liquid from leaking.

[0074] At the same time, after the casting is completed, the float 105b is lifted up by the mother liquid and enters the nozzle 105 to scrape and remove excess mother liquid. At the same time, when the gravity of the float 105b decreases, the spring pulls the lifting rod 304a to move upward, and the lifting rod 304a rises and contacts and pushes the connecting rod 304. At the same time, under the pull of the second elastic member 105c-1, the original balance of the piston 105c is broken, and the connecting rod 304 and the piston 105c rise, blocking the nozzle 105, thereby realizing the automatic stop of the casting.
