DETAILED DESCRIPTION

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0039] See also Figures 1 to 4 As shown, the present application provides an injection molding machine shooting platform, and the injection molding machine shooting platform of the present application is mainly installed on a horizontal injection molding machine, and can also be used on a vertical injection molding machine. The injection molding machine shooting platform mainly melts plastic particles and pushes the plastic in a molten state into the mold. The injection molding machine shooting platform of the present application includes: a bracket 100, an injection actuator 200, an oil pump 300 and a motor 400. The bracket 100 can be understood as a supporting structure of the injection molding machine shooting platform. An oil cylinder is provided in the injection actuator 200, and the oil cylinder can also be understood as a hydraulic cylinder. Under the pushing action of the hydraulic oil in the hydraulic cylinder, the molten plastic in the injection actuator 200 can be pushed out.

[0040] The bracket 100 is provided with an oil tank 110 for storing hydraulic oil. The bracket 100 is generally made of metal, and the oil tank 110 is embedded in the bracket 100, which saves the space occupied by the oil tank 110 when it is placed outside, making the overall structure more compact. At the same time, the distance between the oil pump 300 and the oil tank 110 is closer, and the oil pump 300 can quickly push the hydraulic oil when it is running.

[0041] The injection actuator 200 includes an oil cylinder 210 and a melt motor 220. The melt motor 220 is slidably disposed on the upper side of the bracket. The oil cylinder 210 is fixed on the upper side of the bracket and is located at the front end of the melt motor 220. The melt motor 220 can drive the screw to rotate. The rotation of the screw brings the solid plastic from the hopper into the barrel, and the plastic is gradually heated by the shearing and friction of the screw.

[0042] The oil pump 300 is embedded in the oil tank 110 and connected to the oil cylinder 210 of the injection actuator 200; the motor 400 is set corresponding to the oil pump 300 and is drivingly connected to the oil pump 300. The oil pump 300 runs in the oil tank 110 to form high-pressure oil to push the oil cylinder 210 of the injection actuator 200 to perform the injection operation. When performing the injection operation, the motor 400 drives the oil pump 300 to run, and when the oil pump 300 runs, the hydraulic oil pump 300 is sent to the oil cylinder 210 of the hydraulic system.

[0043] The oil pump 300 and the motor 400 form a power mechanism. When performing injection operation, the power mechanism serves as a power source. The motor 400 operates to drive the oil pump 300 to work. The oil pump 300 sucks oil from the oil tank 110 through the oil suction port and discharges high-pressure oil from the oil outlet to the injection actuator 200. The high-pressure oil drives the injection actuator 200 to perform functional actions under the control of the valve plate.

[0044] In the present embodiment, the oil pump 300 is arranged in the oil tank 110, and the oil tank 110 stores hydraulic oil. The vibration generated by the oil pump 300 during operation will be transmitted to the hydraulic oil, and the vibration will drive the hydraulic oil to vibrate. However, in this process, the mechanical vibration will be converted into liquid vibration, which consumes the energy generated by the vibration of the oil pump 300. In other words, the hydraulic oil can absorb the vibration generated by the oil pump 300, so that the vibration of the oil pump 300 is difficult to be transmitted to the outside, thereby reducing the vibration of the external mechanical structure and the vibration of the external air. Thereby, the generation of noise is reduced, making the injection molding machine of the present application quieter. Moreover, since the vibration of the injection molding machine itself is reduced, the vibration of the connection positions of each component is also reduced synchronously, the stability of the connection is higher, and the situation of the connection position of the component is reduced.

[0045] In addition, the motor and oil pump in this application are standard parts, and it is easy to find replacements after a failure occurs. The cost of use is low, and the quality of standard parts is more stable, reducing the failure of the injection molding machine during operation.

[0046] In order to clearly understand the injection molding principle of the injection actuator 200, the following example is given. The injection actuator 200 also includes a barrel, a screw, a hopper and a heater. The heater is arranged on the periphery of the barrel, the screw is arranged inside the barrel, and the hopper is generally arranged above the barrel. Plastic particles are added into the barrel through the hopper. The heater can release heat to the barrel. After the plastic particles are affected by the heat, the plastic melts and deforms to form a molten plastic. The hydraulic system pushes the screw to move. Under the pushing action of the screw, the molten plastic is squeezed out of the barrel, thereby completing the injection molding operation.

[0047] The injection actuator 200 also includes a check ring, and the working principle of the check ring is similar to that of a hydraulic check valve. When the screw rotates and plasticizes, the molten material transported from the screw groove to the screw head has a certain pressure, which pushes the check ring forward. During injection, the screw moves forward to apply pressure to the molten material at the front end, and the check ring is also moved backward by the pressure of the molten material at the front end. That is, the conical surface of the check ring fits with the cone of the screw body to form a molten backflow seal, so that the molten material at the front end of the screw head cannot flow back.

[0048] The check ring has two functions: one is to close the check ring at the beginning of the injection cycle when the thermoplastic melt is injected into the mold cavity. The other function is to open the check ring to provide a flow path for the polymer when the screw retreats and the polymer has been plasticized and is ready for the next injection.

[0049] The oil tank 110 is arranged at one end of the bracket 100, and the motor 400 is arranged facing the oil tank 110. The motor 400 is arranged opposite to the oil tank 110, so that the motor 400 can be connected to the oil pump 300 in the oil tank 110. In addition, the motor 400 is also fixed at one end of the bracket 100, and when the bracket 100 moves, the motor 400 also moves synchronously. The other end of the bracket 100 can be hollowed out to reduce the overall weight of the bracket 100.

[0050] In one embodiment of the present application, the injection molding machine shooting platform also includes a connector 500 and a coupling 600. The connector 500 is arranged between the oil pump 300 and the motor 400. The coupling 600 is passed through the connector 500. One end of the coupling 600 is connected to the oil pump 300, and the other end is connected to the motor 400. The coupling 600 is also called a coupling, which is used to firmly connect the motor 400 and the oil pump 300 and operate together. In other words, the oil pump 300 and the motor 400 can be driven and connected together through the coupling 600. When the motor 400 is running, the driving force can be transmitted to the oil pump 300 through the coupling 600.

[0051] In addition, the connector 500 can also well fix the motor 400, fix the motor 400 to one end of the bracket 100, maintain the relative position between the motor 400 and the bracket 100, and improve the firmness of the position of the motor 400 in the bracket 100. When the coupling 600 passes through the connector 500, the connector 500 plays a certain supporting role for the coupling 600. The connector 500 also protects the periphery of the coupling 600, reduces the damage to the coupling 600 by external forces, and thus can also protect the coupling 600 to a certain extent.

[0052] In one embodiment of the present application, the connector 500 and the bracket 100 are arranged to form an oil tank 110, and a spacing space 111 is formed between the oil pump 300 and the inner wall surface of the oil tank 110, and the spacing space 111 is used to fill hydraulic oil. The coupling 600 can pass through the connector 500 and connect with the oil pump 300. It can be known that one end of the oil pump 300 is connected to the coupling 600, and the rest of the surface of the oil pump 300 is suspended in the air, and the oil pump 300 and the inner wall surface of the oil tank 110 are separated by a certain distance, that is, the spacing space 111 is formed. Hydraulic oil is stored in the oil tank 110, and the hydraulic oil is filled in the spacing space 111, so that the oil pump 300 is basically wrapped by the hydraulic oil. When the oil pump 300 vibrates during operation, the hydraulic oil can absorb the vibration energy well.

[0053] It can be seen from the above that part of the structure of the oil tank 110 has been completed synchronously when the bracket 100 is processed, that is, when the bracket 100 is cast, part of the structure of the oil tank 110 is formed integrally.

[0054] In addition, the oil tank 110 can also be an independent structure, which can be embedded in the bracket 100 by installation, and can also be removed from the bracket 100 as needed. In this way, the assembly of the oil tank 110 is more flexible and easy to replace as needed.

[0055] See also Figures 4 to 7 As shown, in one embodiment of the present application, the connector 500 includes a first connecting plate 510, a second connecting plate 520 and a fixing member 530; the bracket 100 forms a cavity with an opening at one end, and the first connecting plate 510 is sealed at the opening of the cavity of the bracket 100 to form an oil tank 110; the first connecting plate 510 is connected to the bracket 100 to form the oil tank 110. When installing the first connecting plate 510, the oil pump 300 and the coupling 600 can be installed on the first connecting plate 510 first.

[0056] Furthermore, in order to make the hydraulic oil absorb vibration more evenly, the coupling 600 can pass through the center of the first connecting plate 510, so that the oil pump 300 is also basically located in the middle of the oil tank 110, and the distance between the oil pump 300 and the inner wall surface of the oil tank 110 is basically equal, and the hydraulic oil can absorb the vibration of the oil pump 300 more evenly. After the coupling 600 and the first connecting plate 510 are installed, the oil pump 300 is connected to the passing coupling 600, and then the first connecting plate 510 with the oil pump 300 is docked at the cavity opening of the bracket 100.

[0057] The second connecting plate 520 is connected to the motor 400, the fixing member 530 is fixed between the first connecting plate 510 and the second connecting plate 520, the coupling 600 is passed through the first connecting plate 510 and the second connecting plate 520, and the first connecting plate 510 and the second connecting plate 520 are arranged at intervals to form a working port 501. The fixing member 530 is arranged between the first connecting plate 510 and the second connecting plate 520, and it can be considered that the fixing member 530, the first connecting plate 510 and the second connecting plate 520 are arranged as a whole. It can also be considered that the first connecting plate 510, the second connecting plate 520 and the fixing member 530 are relatively independent, and the first connecting plate 510 and the second connecting plate 520 are fixed together by the connection and fixing of the fixing member 530.

[0058] During installation, the motor 400 can be pre-arranged at the position of the second connecting plate 520, the coupling 600 also passes through the second connecting plate 520, and the motor 400 is connected to the position where the coupling 600 passes through the second connecting plate 520. When docking and installing with the bracket 100, the motor 400, the connector 500 and the oil pump 300 as an integral structure can be docked at the position of the bracket 100, which can improve the installation efficiency.

[0059] In addition, the injection molding machine shooting platform also includes fasteners. When the first connecting plate 510 is connected to the bracket 100, the fasteners are inserted into the first connecting plate 510 and the bracket 100 to fix the first connecting plate 510 and the bracket 100 together. It is convenient to apply force to the fastener through the working opening. For example, if the fastener is a screw, it is convenient to apply torsional force through the working opening 501, so that the screw can be turned so that the screw is tightly fixed on the first connecting plate 510. Generally, four fasteners are provided, and one fastener is provided at each of the four corners of the first connecting plate 510. Of course, the number of fasteners can also be more, such as five or six.

[0060] Furthermore, the injection molding machine shooting platform may further include a sealing ring, which may be made of rubber and is disposed between the first connecting plate 510 and the bracket 100. Generally, the first connecting plate 510 and the bracket 100 have relatively hard structures, and poor sealing may occur when the two are butted together. By providing the sealing ring, the butt gap between the first connecting plate 510 and the bracket 100 may be reduced, thereby improving the sealing effect between the first connecting plate 510 and the bracket 100.

[0061] In one embodiment of the present application, the injection molding machine shooting platform also includes an air storage box 710, which is used to store pressurized gas. The air storage box 710 is arranged on the bracket 100 or the injection actuator 200, and the air storage box 710 is connected to the oil tank 110. The pressurized gas stored in the air storage box 710 has a high pressure and belongs to high-pressure gas. The pressurized gas is generally a gas with stable performance, such as nitrogen or inert gas. The pressure of the pressurized gas is greater than the standard atmospheric pressure. The oil tank 110 is ventilated by the pressurized gas. The high-pressure pressurized gas can play a certain role in promoting the hydraulic oil in the oil tank 110. The action of the oil pump 300 can increase the flow speed of the hydraulic oil, so that the hydraulic oil can flow to the oil cylinder 210 faster. In addition, it can be known that the air storage box 710 can be arranged on the bracket 100, and can also be arranged on the injection actuator 200.

[0062] In the related art, due to the setting of the accumulator, the entire injection molding structure is large in size, heavy in weight, highly integrated, and inconvenient to maintain. It is also inconvenient to install, too large in size, unstable in center of gravity, not firmly fixed, and the entire power unit is prone to shaking or vibrating. In the present application, the accumulator structure in the related art is replaced by the setting of the air tank 710 and the oil tank 110. The structure is made more dispersed, the structural space is fully utilized, and the volume of the injection molding power unit is reduced. The air tank 710 and the oil tank 110 are separated to reduce the weight of the power unit, thereby reducing the shaking. In addition, the separate setting also avoids excessive integration, facilitates targeted repairs, and reduces repair costs.

[0063] The oil tank is connected to the air tank and built into the bracket to form a high-pressure closed oil tank. This improves the oil pump's oil suction efficiency and can also simultaneously improve the performance of the power system.

[0064] In one embodiment of the present application, the air storage box 710 is arranged on the bracket 100, and the injection molding machine shooting platform further includes a hose 720; the air storage box 710 is provided with a first connection hole, and the side wall surface of the bracket 100 is provided with a second connection hole, the second connection hole is provided corresponding to the oil tank 110, and the second connection hole is connected to the oil tank 110, one end of the hose 720 is connected to the first connection hole, and the other end is connected to the second connection hole. Through the connection of the hose 720, the pressurized gas can be passed to the oil tank 110.

[0065] The setting of the hose 720 is convenient for connection and installation. The hose 720 can be understood as a relatively soft tube that can withstand a certain stretching deformation and maintain connectivity. For example, the hose 720 can be a rubber tube.

[0066] In order to reduce the arbitrary deformation of the hose 720, the injection molding machine shooting platform of the present application includes a guide sleeve 730, which is sleeved on the outer periphery of the hose 720, and the extension direction of the guide sleeve 730 is parallel to the moving direction of the melt motor 220. In addition, the guide sleeve 730 is located between the oil tank 110 and the air storage box 710. Through the setting of the guide sleeve 730, the hose 720 can be well extended between the air storage box 710 and the oil tank 110, reducing the tortuosity of the hose 720.

[0067] Of course, in the present application, a hard pipe can also be used to connect between the air storage tank 710 and the oil tank 110.

[0068] In one embodiment of the present application, the injection molding machine shooting platform further includes a valve plate 800, which is arranged on the injection actuator 200; the injection molding machine shooting platform further includes a power pipe 810 and an oil return pipe 820, one end of the power pipe 810 is passed through the side wall of the bracket 100 and connected to the oil pump 300, and the other end is connected to the valve plate 800, and one end of the oil return pipe 820 is connected to the oil tank 110, and the other end is connected to the valve plate 800. The hydraulic oil pumped by the oil pump 300 is output to the valve plate 800 through the power pipe 810, and when the oil is returned, the hydraulic oil flows back from the valve plate 800 to the oil tank 110 through the oil return pipe 820.

[0069] The power pipe 810 and the oil return pipe 820 are both hard pipes, and the material is relatively hard, generally made of metal, such as stainless steel pipe or copper pipe. The inner wall of the hard pipe is relatively smooth, which can reduce the resistance of the hydraulic oil in contact with it, increase the flow speed of the hydraulic oil, reduce the power loss of the hydraulic oil, and make the injection molding machine shooting platform respond faster during the injection operation.

[0070] In one embodiment of the present application, the valve plate 800 and the air tank 710 are arranged on opposite sides of the injection actuator 200. Various valves are installed on the valve plate 800, and precise control of the hydraulic oil is achieved through the valves. The material of the air tank 710 is generally metal, and it can also be a composite material with high strength to ensure that the air tank 710 can withstand a certain gas pressure. The valve plate 800 and the air tank 710 both have a certain weight. By setting the valve plate 800 and the air tank 710 separately, the left and right weights of the injection molding machine shooting platform can be balanced, making the center of gravity of the injection molding machine shooting platform more stable. Moreover, setting the valve plate 800 and the air tank 710 separately on both sides can also make the overall structure more concise.

[0071] The valve plate 800 includes various valves for controlling the flow of hydraulic oil. When the hydraulic oil pressure decreases or the oil flow reverses, the spring of the check valve pushes the valve core to close, prohibiting the hydraulic oil from flowing in the opposite direction and preventing the oil from flowing back.

[0072] The injection actuator 200 generally includes two left-right symmetrical oil cylinders 210 . The valve plate 800 connects the two oil cylinders 210 to control the delivery of hydraulic oil to the oil cylinders 210 and to control the return of the hydraulic oil.

[0073] Various valves can be integrated into one structure in the valve plate 800. For example, electromagnetic reversing valves can also be arranged in the valve plate 800, and these electromagnetic reversing valves control the opening and closing of the liquid flow through electromagnetic action to achieve precise control.

[0074] A solenoid valve can also be provided in the valve plate 800. The solenoid valve is a commonly used control element in the injection molding machine, and controls the opening and closing of the valve by turning the electromagnet on and off. For example, a direct-acting high-pressure solenoid valve, a stainless steel valve body solenoid valve, etc., these valves have the characteristics of fast response speed and precise control.

[0075] A ball valve may also be provided in the valve plate 800 . The ball valve is mainly used to control the on-off of the fluid in the injection molding machine.

[0076] A throttle valve may also be provided in the valve plate 800, and the throttle valve is used to adjust the flow rate and flow velocity of the fluid, for example, a one-way throttle valve, a hydraulic one-way valve, etc. These valves play an important role in flow control in the hydraulic system of the injection molding machine to ensure the stable operation of the system.

[0077] In one embodiment of the present application, the injection molding machine shooting platform further includes a slide 900 and a first slide rail 910; the bracket 100 is arranged above the first slide rail 910, at least four slides 900 are arranged, and the four slides 900 are arranged around the bracket 100, and the slides 900 are slidably connected with the first slide rail 910; the slides 900 can be fixed around the bracket 100, and the bracket 100 can slide on the first slide rail 910 through the connection between the slides 900 and the first slide rail 910. Through the arrangement of the four slides 900, the contact position between the bracket 100 and the first slide rail 910 is relatively balanced, reducing the problem of the bracket 100 shaking left and right.

[0078] The slide foot 900 may be provided with fixing parts 120 pre-arranged on the sides of the bracket 100, and the four fixing parts 120 are symmetrically arranged, and the fixing parts 120 may protrude from the sides of the bracket 100. One end of the slide foot 900 is fixed to the fixing part 120, and the other end of the slide foot 900 is slidably docked on the first slide rail 910.

[0079] The injection molding machine shooting platform also includes a second slide rail 920, which is disposed on the upper side of the bracket 100, and the melt motor 220 is disposed on the second slide rail 920. A plurality of sliding connection points may be disposed between the melt motor 220 and the second slide rail 920, and the positions of the sliding connection points may be evenly distributed, so as to ensure stable sliding of the melt motor 220 relative to the second slide rail 920.

[0080] The present application also provides an injection molding machine, which is also called an injection molding machine or an injection machine. The injection molding machine is the main molding equipment that uses a plastic molding mold to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. The injection molding machine is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it ejected and fill the mold cavity.

[0081] In the present application, the injection molding machine includes an injection molding machine shooting platform. The working process of the injection molding machine can be carried out according to cycles, and each cycle mainly includes: quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, and mold opening and taking out the plastic parts. After taking out the plastic parts, the mold is closed again to carry out the next cycle.

[0082] The working principle of the injection molding machine can be further explained as follows: the injection molding machine heats the plastic particles to melt them, and then injects the molten plastic into the mold through a screw or plunger. The mold is heated and cooled in the injection molding machine, and the plastic solidifies and forms in the mold, eventually forming the desired plastic product.

[0083] Among them, quantitative feeding is to add plastic particles into the hopper of the injection molding machine. Melt plasticization is to melt and plasticize plastic particles in the heating system of the injection molding machine. Pressure injection is to inject molten plastic into the mold under the thrust of the screw or plunger. Mold filling and cooling is to cool and solidify the plastic in the mold. Mold opening and taking out is to open the mold after cooling and take out the molded plastic product.

[0084] The injection molding machine shooting platform of the injection molding machine of the present application is mainly installed on a horizontal injection molding machine. The injection molding machine shooting platform of the present application includes: a bracket 100, an injection actuator 200, an oil pump 300 and a motor 400. The bracket 100 is a supporting structure of the injection molding machine shooting platform. The injection actuator 200 includes an oil cylinder 210 and a melt motor 220, the melt motor 220 is slidably arranged on the upper side of the bracket, and the oil cylinder 210 is fixed on the upper side of the bracket and is located at the front end of the melt motor 220. The oil cylinder 210 can also be understood as a hydraulic cylinder. Under the driving action of the hydraulic oil in the hydraulic cylinder, the molten plastic in the injection actuator 200 can be pushed out. An oil tank 110 is arranged in the bracket 100, and the oil tank 110 is used to store hydraulic oil; the bracket 100 is generally made of metal, and it can be said that the oil tank 110 is embedded in the bracket 100, which saves the space occupied by the oil tank 110 when it is external, making the overall structure more compact.

[0085] The melt motor 220 is slidably arranged on the upper side of the bracket 100, so that the melt motor 220 can move. The oil pump 300 is embedded in the oil tank 110 and connected to the oil cylinder 210 of the injection actuator 200; the motor 400 is arranged corresponding to the oil pump 300 and is drivingly connected to the oil pump 300. The oil pump 300 runs in the oil tank 110 to push the oil cylinder 210 of the injection actuator 200 to perform the injection operation. When performing the injection operation, the motor 400 drives the oil pump 300 to operate, and when the oil pump 300 is in operation, the hydraulic oil pump 300 is sent to the oil cylinder 210 of the hydraulic system.

[0086] In the injection molding machine of this embodiment, the oil pump 300 is arranged in the oil tank 110, and the oil tank 110 stores hydraulic oil. The vibration generated by the oil pump 300 during operation will be transmitted to the hydraulic oil, and the vibration will drive the hydraulic oil to vibrate. However, in this process, the mechanical vibration will be converted into liquid vibration, which consumes the energy generated by the vibration of the oil pump 300. In other words, the hydraulic oil can absorb the vibration generated by the oil pump 300, so that the vibration of the oil pump 300 is difficult to be transmitted to the outside, thereby reducing the vibration of the external mechanical structure, and can also reduce the vibration of the external air, thereby reducing the generation of noise.
