Description

Technical Field

[0001] This utility model relates to a hot press molding machine, specifically a hot press molding machine with automatic feeding function. Background Technology

[0002] Hot press molding machines (also known as flat vulcanizing machines, rubber vulcanizing machines, and foam board vulcanizing machines) are industrial equipment that uses an intelligent constant temperature system with electric heating plates to apply pressure to form raw materials. Its core structure consists of a frame, a heating device, and a pressure actuator. Hot press molding machines are widely used in the molding and processing of rubber, plastics, EVA materials, and carbon fiber products, covering industrial fields such as 3C electronics and automobile manufacturing.

[0003] Currently, many thermoforming machines still rely on manual feeding. For example, in the production and processing of shoe soles, workers need to manually push the mold containing the raw materials into the forming machine. After forming, the hot mold still needs to be manually pulled out, which is time-consuming and labor-intensive. To address this, we propose a thermoforming machine with automatic feeding function. Utility Model Content

[0004] The purpose of this invention is to provide a hot press molding machine with automatic feeding function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hot press forming machine with automatic feeding function includes a processing table. A top seat is fixedly connected to the top of the processing table via multiple columns. A hydraulic cylinder is fixedly installed on the top of the top seat. An upper heating plate is installed at the push rod end of the hydraulic cylinder. A lower heating plate is fixedly installed on the top of the processing table corresponding to the upper heating plate. A support plate is fixedly installed on the outer wall of the processing table. An annular turntable is rotatably installed on the top of the support plate, located above the lower heating plate. Multiple slots are circumferentially distributed on the annular turntable.

[0025] Please see Figures 1-5In this embodiment of the present invention, a hot press forming machine with automatic feeding function includes a processing table 1. A top seat 3 is fixedly connected to the top of the processing table 1 via multiple columns 2. A hydraulic cylinder 4 is fixedly installed on the top of the top seat 3. An upper heating plate 7 is installed on the push rod end of the hydraulic cylinder 4. A lower heating plate 8 is fixedly installed on the top of the processing table 1 at a position corresponding to the upper heating plate 7. A support plate 9 is fixedly installed on the outer wall of the processing table 1. An annular turntable 13 is rotatably installed on the top of the support plate 9. The annular turntable 13 is located at the lower heating plate. Above the hot plate 8, the annular turntable 13 has multiple slots 15 arranged in a circular pattern. A lower mold 16 is movably inserted into each slot 15. The top of the lower mold 16 is connected to an upper mold 18 via a hinge seat 17. A handle 19 is fixedly installed on the outer wall of the hinge seat 17. An arc-shaped support rod 11 is fixedly installed on the top of the processing table 1 and the support plate 9. The arc-shaped support rod 11 is located on the moving path of each slot 15. A reduction stepper motor 20 for driving the annular turntable 13 is installed on the support plate 9.

[0026] By adopting the above-described solution, this utility model allows for the following steps: after installing the required molds in each of the opening slots 15, raw materials are added to the molds. Then, the deceleration stepper motor 20 is activated to drive the annular turntable 13 to rotate on the support plate 9 until one of the opening slots 15 moves directly above the lower heating plate 8. The lower mold 16 in this opening slot 15 then falls from the arc-shaped support rod 11 onto the surface of the lower heating plate 8. The hydraulic cylinder 4 is then activated to drive the upper heating plate 7 to move downwards. The upper heating plate 7 and the lower heating plate 8 can then be used to apply pressure and heat to the mold, completing the hot pressing of the product. During this process, the mold located outside the processing table 1 can be used for loading and unloading of the molded product and raw materials. After the hot pressing is completed, the upper heating plate 7 is reset, and the deceleration stepper motor 20 is activated again to drive the annular turntable 13 to rotate, thereby moving the upper mold 18 on the lower heating plate 8 to the outside of the processing table 1. This eliminates the need for workers to manually push and pull the high-temperature molds, making the process more labor-saving.

[0027] Specific combination Figure 3 and Figure 5 In one embodiment of the present invention, the two ends of the arc-shaped support rod 11 are located on both sides of the lower heating plate 8. A slope 12 is provided at one end of the top of the arc-shaped support rod 11. The lowest point of the slope 12 is lower than the top surface of the lower heating plate 8, and the top surface of the other end of the arc-shaped support rod 11 is higher than the top surface of the lower heating plate 8.

[0028] The top surface of one end of the arc-shaped support rod 11 is designed to be higher than the top surface of the lower heating plate 8, which facilitates the lower mold 16 to slide down the arc-shaped support rod 11 onto the surface of the lower heating plate 8 under the action of the annular turntable 13. The slope 12 facilitates the lower mold 16 to return to the arc-shaped support rod 11 under the action of the annular turntable 13.

[0029] Specific combination Figure 1 , Figure 3 and Figure 4 In one embodiment of the present invention, an arc-shaped guide rail 10 is fixedly installed on the top of the pallet 9, and a plurality of sliding sleeves 14 are fixedly installed on the bottom of the annular turntable 13, the sliding sleeves 14 being adapted to the arc-shaped guide rail 10.

[0030] By setting up the arc-shaped guide rail 10 and the sliding sleeve 14, the stability of the annular turntable 13 rotating on the support plate 9 can be improved.

[0031] Specific combination Figure 1-4 In one embodiment of the present invention, the output shaft of the deceleration stepper motor 20 is fixedly connected to a gear 21, and an internal gear ring 22 is fixedly installed at the bottom of the annular turntable 13, the internal gear ring 22 meshing with the gear 21.

[0032] By driving the gear 21 to rotate through the stepper motor 20, the gear 21 and the internal gear ring 22 can be used to drive the annular turntable 13 to rotate on the support plate 9.

[0033] Specific combination Figure 2-4 In one embodiment of this utility model, positioning protrusions 23 are fixedly provided on the inner wall of the annular turntable 13 and at the corresponding positions of each opening slot 15. A proximity switch 24 is fixedly installed on the top of the support plate 9. The proximity switch 24 is located inside the annular turntable 13. The proximity switch 24 and the deceleration stepper motor 20 are electrically connected to the same PLC controller.

[0034] The positioning bump 23 and the proximity switch 24 make it easy to accurately stop the opening slot 15 on the annular turntable 13 directly above the lower heating plate 8.

[0035] Specific combination Figure 1 and Figure 5 In one embodiment of the present invention, a plurality of support pillars 25 are fixedly installed at the bottom of the tray 9 to ensure the stability of the tray 9.

[0036] Specific combination Figure 1 In one embodiment of this utility model, a connecting seat 5 is fixedly installed on the push rod end of the hydraulic cylinder 4, and a guide sleeve 6 is slidably sleeved on the outer wall of the column 2. The guide sleeve 6 is fixedly connected to the connecting seat 5, and the upper heating plate 7 is fixedly installed at the bottom of the connecting seat 5. Through the sliding cooperation between the guide sleeve 6 and the column 2, the stability of the upper heating plate 7 moving up and down can be improved.
