Description

Technical Field

[0001] This utility model is a plastic compression molding die, belonging to the field of plastic processing technology. Background Technology

[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector in the plastics industry. Plastic processing generally includes plastic formulation, molding, machining, joining, finishing and assembly. Plastics are materials made primarily of natural or synthetic resins with various additives, which can be molded into a certain shape under certain temperature and pressure conditions and retain their shape at room temperature.

[0003] However, existing plastic compression molding dies have some drawbacks in application: Existing molds do not have a cooling structure after the plastic is pressed and molded, resulting in a slow cooling rate, reduced demolding efficiency, and consequently, a slower molding speed for plastic products. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic compression molding die.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A plastic compression molding die includes a worktable. A lower mold base and a support plate are provided on one side of the top of the worktable. The support plate is located on the side of the lower mold base. An electric telescopic rod is provided on the top of the support plate. The output end of the electric telescopic rod passes through the support plate and is connected to the top of an upper mold base. The upper mold base cooperates with the lower mold base. A cooling mechanism is provided on the other side of the top of the worktable.

[0006] Furthermore, the cooling mechanism includes a cooler fan fixedly connected to the other side of the top of the workbench. The cooler fan has an air inlet on its right side and an air outlet on its left side. The air outlet is connected to a connecting pipe. An air nozzle is provided at the end of the connecting pipe away from the cooler fan. A fixed sleeve is fixedly connected to the outer surface of the connecting pipe. The air nozzle is located inside the fixed sleeve. A movable component that cooperates with the connecting pipe is provided on one side of the top of the workbench. An opening and closing component that cooperates with the connecting pipe is provided on the side of the lower mold base near the cooler fan. An air outlet is provided on the left side of the lower mold base.

[0007] Furthermore, the moving component includes a fixed base fixedly connected to the top of the workbench. A motor is provided on one side of the top of the fixed base. A disc is connected to the output end of the motor. An arc-shaped groove is provided on the disc. A sleeve plate is fitted on the disc. A fixing rod is provided at the end of the sleeve plate. The fixing rod passes through the arc-shaped groove.

[0008] Furthermore, the movable component also includes a lower annular fixing member fixedly connected to the sleeve plate away from the top of the disc. The top of the lower annular fixing member is provided with an upper annular fixing member. The lower annular fixing member and the upper annular fixing member are connected by bolts. The lower annular fixing member and the upper annular fixing member form a circular fixing hole. The fixing sleeve is located in the circular fixing hole.

[0009] Furthermore, the opening and closing assembly includes a through hole on one side of the lower mold base, a through groove on the top of the through hole near the interior of the lower mold base, a blocking plate slidably connected in the through groove, a spring connecting the side of the blocking plate to the inner wall of the through groove, the end of the fixing sleeve penetrating into the through hole, and a slope on the bottom end of the blocking plate near the fixing sleeve, the end of the fixing sleeve being pressed against the slope.

[0010] Furthermore, an accommodating hole is provided on one side of the workbench, and an electric telescopic rod is provided at the bottom of the accommodating hole. The output end of the electric telescopic rod extends through the lower mold base and connects to the base plate. A through-hole communicating with the accommodating hole is provided at the middle of the bottom end of the lower mold base.

[0011] Furthermore, a controller is provided on the top of the workbench, and the electric telescopic rod one, the electric telescopic rod two, the air cooler and the motor are all electrically connected to the controller.

[0012] The beneficial effects of this utility model are: By designing the cooling components, when the air cooler is turned on, air enters the air cooler from the air inlet, then passes through connecting pipes and finally is sprayed onto the product through the air outlet nozzle, which can cool the product and improve the demolding efficiency of the molded product.

[0013] By designing a movable component, when product cooling is required, the movable component can be driven to move the fixed sleeve and connecting pipe through the through hole, thereby pushing the plug plate upward out of the through hole, so that cold air can be sprayed out of the connecting pipe to cool the product.

[0014] Through the design of the opening and closing components, when the plastic is being molded, the blocking plate is located inside the through hole to block the through hole and facilitate the molding process. When the product needs to be cooled, the moving component drives the fixed sleeve to move, which will push the blocking plate away from the through hole, making it easier to connect the pipe to spray cold air to cool the product.

[0015] When material needs to be unloaded, the second electric telescopic rod can be activated. The output end of the second electric telescopic rod moves upward, driving the base plate to move. The base plate then drives the product formed in the lower mold base to move downward, thus completing the demolding process.

[0016] Through the design of the lower annular fastener, the upper annular fastener and the bolt, the fixing sleeve is located in the circular fixing hole formed by the lower annular fastener and the upper annular fastener, and is fixed by bolt connection. At this time, the fixing sleeve is tightly connected with the lower annular fastener. When the moving component drives the lower annular fastener to move, it will in turn drive the fixing sleeve to move. Attached Figure Description

An opening and closing component that cooperates with the connecting pipe 9 is provided on the side of the lower mold base 2 near the cooler 8. An air outlet 23 is provided on the left side of the lower mold base 2. Through the design of the cooling component, when the cooler 8 is started, air enters the cooler 8 from the air inlet, then passes through the connecting pipe 9 and finally sprays onto the product through the air nozzle, which can cool the product and improve the demolding efficiency of the molded product.

[0023] See Figure 1-6The moving assembly includes a fixed base 11 fixedly connected to the top of the workbench 1. A motor 12 is provided on one side of the top of the fixed base 11. The output end of the motor 12 is connected to a disc 13. An arc-shaped groove 14 is formed on the disc 13. A sleeve plate 15 is fitted on the disc 13. A fixing rod 16 is provided at the end of the sleeve plate 15. The fixing rod 16 passes through the arc-shaped groove 14. The moving assembly also includes a lower annular fixing member 17 fixedly connected to the sleeve plate 15 away from the top of the disc 13. The top of the lower annular fixing member 17... An upper annular fixing member 18 is provided, and a lower annular fixing member 17 is connected to the upper annular fixing member 18 by bolts 19. The lower annular fixing member 17 and the upper annular fixing member 18 form a circular fixing hole. The fixing sleeve 10 is located in the circular fixing hole. Through the design of the moving component, when the product needs to be cooled, the moving component can be driven to move the fixing sleeve 10 and the connecting pipe 9 through the through hole 20, thereby pushing the blocking plate 21 upward to move out of the through hole 20, so that the connecting pipe 9 can spray cold air to cool the product.

[0024] See Figure 1-6 The opening and closing assembly includes a through hole 20 on one side of the lower mold base 2. A through groove 22 is provided on the top of the through hole 20 near the inside of the lower mold base 2. A blocking plate 21 is slidably connected in the through groove 22. A spring 25 is connected between the side of the blocking plate 21 and the inner wall of the through groove 22. The end of the fixing sleeve 10 extends into the through hole 20. The bottom end of the blocking plate 21 near the fixing sleeve 10 has an inclined surface. The end of the fixing sleeve 10 is pressed against the inclined surface. Through the design of the opening and closing assembly, when the plastic is being molded, the blocking plate 21 is located in the through hole 20 to block the through hole 20, which facilitates the molding process of the plastic. When the product needs to be cooled, the moving assembly moves the fixing sleeve 10, which pushes the blocking plate 21 away from the through hole 20, so that the connecting pipe 9 can spray cold air to cool the product.

[0025] See Figure 1-6 The workbench 1 has an internal receiving hole 24 on one side. The bottom of the receiving hole 24 is provided with an electric telescopic rod 6. The output end of the electric telescopic rod 6 passes through the lower mold base 2 and connects to the base plate 7. The bottom center of the lower mold base 2 has a through opening that communicates with the receiving hole 24. When it is necessary to unload the material, the electric telescopic rod 6 can be activated. The output end of the electric telescopic rod 6 moves upward, driving the base plate 7 to move. The base plate 7 drives the formed product in the lower mold base 2 to move downward, thus completing the demolding work.

[0026] See Figure 1-6The top of the workbench 1 is equipped with a controller, and the electric telescopic rod 4, the electric telescopic rod 6, the air cooler 8 and the motor 12 are all electrically connected to the controller.

[0027] The circuits, electronic components, controllers, and modules involved are all existing technologies that can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this application does not involve any improvement to the software and methods.

[0028] In use, the electric telescopic rod 4 is activated. The output end of the electric telescopic rod 4 drives the upper mold base 5 to move downward. With the cooperation of the lower mold base 2, the plastic can be molded. Subsequently, the molded product can be cooled. The operation process is as follows: The motor 12 is activated, which drives the disc 13 to rotate. The rotation of the disc 13 drives the arc groove 14 to rotate. When the inner wall of the arc groove 14 rotates, it presses the fixing rod 16, thereby driving the fixing rod 16 to move. The movement of the fixing rod 16 drives the sleeve plate 15 to move. The sleeve plate 15 drives the lower annular fixing member 17 at the top to move. When the lower annular fixing member 17 moves, it drives the upper annular fixing member... 18 moves with the fixed sleeve 10, and the fixed sleeve 10 drives the connecting pipe 9 to move. As the fixed sleeve 10 moves into the interior of the mold base 2 through the through hole 20, the end of the fixed sleeve 10 presses the inclined surface of the side of the blocking plate 21, thereby pushing the blocking plate 21 to move upward along the through groove 22. When the blocking plate 21 moves upward, it presses the spring 25. As the blocking plate 21 moves upward, it opens the through hole 20. Then, the air cooler 8 is started. Air enters the air cooler 8 from the air inlet end of the air cooler 8, and then passes through the connecting pipe 9 and finally sprays it onto the product through the air outlet nozzle. At this time, the air outlet nozzle in the fixed sleeve 10 corresponds to the product and can cool the product. When material needs to be unloaded, the electric telescopic rod 6 can be activated. The output end of the electric telescopic rod 6 moves upward, driving the base plate 7 to move. The base plate 7 then drives the product formed in the lower mold base 2 to move downward, thus completing the demolding process.
