Description

Technical Field

[0001] This utility model relates to the field of rubber sheet production technology, and in particular to a plastic mold for rubber sheet production. Background Technology

[0002] Plastic molds for rubber sheet production are tools used to manufacture rubber sheets. They can be customized into various shapes and sizes as needed. These plastic molds usually have a certain degree of heat resistance and durability, and can withstand production processes under high temperature and high pressure conditions.

[0003] Common plastic molds used in rubber sheet production lack auxiliary cooling structures, resulting in a long cooling time required after the rubber sheet is molded. Additionally, the lack of auxiliary demolding structures makes it difficult to demold and remove the rubber sheet after production.

[0004] Therefore, the problems of the lack of auxiliary cooling structure in the plastic molds used for rubber sheet production, which require a long time to cool down, and the lack of auxiliary demolding structure, which makes it difficult to demold and remove the rubber sheet, urgently need to be solved in order to improve the application scenarios. Utility Model Content

[0005] To overcome the problems of common plastic molds used in rubber sheet production lacking auxiliary cooling structures and auxiliary demolding structures.

[0006] The technical solution of this utility model is as follows: a plastic mold for producing rubber sheets includes a lower mold frame, a support column connected to the bottom corner of the lower mold frame, a base plate installed at the lower end of the support column, ceramic heating plates embedded in the front and rear ends of the lower mold frame, fixing plates fixedly installed on the left and right ends of the lower mold frame near the front and rear sides, a lifting plastic component connected to the top of the fixing plate, an auxiliary cooling component installed in the middle right side and inside the lower mold frame, and an auxiliary demolding component installed on the lower mold frame and the base plate near the front end.

[0007] Preferably, the auxiliary cooling component can assist in cooling the raw material after plastic forming, thereby improving production efficiency. The auxiliary demolding component can also be configured to deliver high-pressure air to detach the bottom of the rubber sheet from the lower inner wall of the mold frame, facilitating demolding and removal. This addresses the common problem in plastic molds used for rubber sheet production that lack auxiliary cooling structures, resulting in a long cooling time after molding and making it difficult to remove the rubber sheet after production.

[0008] Preferably, the lifting and shaping component includes a hydraulic cylinder and a connecting bar; the top of the fixed plate is connected to the hydraulic cylinder, and the upper end of the hydraulic cylinder is equipped with a connecting bar.

[0009] Preferably, the lifting and shaping component includes a pressure plate and an upper mold; the pressure plate is set between the connecting strips, and the upper mold is installed at the bottom of the pressure plate. The processed rubber raw material is poured into the lower mold frame, and the ceramic heating plate heats and softens the material. Then, the hydraulic cylinder is controlled to contract, which drives the connecting strips and the pressure plate to descend. The molding process is completed through the upper mold and the lower mold frame.

[0010] Preferably, the auxiliary cooling component includes a delivery pump, a water inlet pipe, and a solenoid valve; the delivery pump is installed at the middle right side of the lower mold frame, the lower end of the delivery pump is connected to the water inlet pipe, and the solenoid valve is installed at the middle of the water inlet pipe. When the solenoid valve is opened, the delivery pump is started, and external cooling water enters the delivery pump through the water inlet pipe.

[0011] Preferably, the auxiliary cooling component includes a first connecting pipe, a heat exchange pipe, and a drain pipe; the first connecting pipe is connected to the right side of the delivery pump, and several heat exchange pipes are equidistantly embedded in the middle of the lower mold frame. The right end of the heat exchange pipe is connected to the upper end of the first connecting pipe, and a drain pipe is provided at the left end of the heat exchange pipe. Cooling water enters the heat exchange pipe through the first connecting pipe to cool the material, accelerate its molding speed, and improve production efficiency.

[0012] Preferably, the auxiliary demolding assembly includes a fixed box, a movable plate, a blocking block, a sealing ring, and an electric lifting rod. The fixed box is embedded at the lower end of the lower mold frame near the front side. Multiple through holes are opened on the top of the fixed box. A movable plate is slidably connected to the inside of the fixed box near the upper end. A blocking block is set at the upper end of the movable plate corresponding to the through holes. A sealing ring is set on the top surface of the movable plate near the blocking block. An electric lifting rod is installed between the bottom of the movable plate and the lower end of the fixed box. After the rubber plate is completely solidified, the electric lifting rod drives the movable plate to descend, at which time the blocking block disengages from the through hole.

[0013] Preferably, the auxiliary demolding component includes an air compressor and a second connecting pipe; the air compressor is connected to the top of the base plate near the front end, and the right end of the air compressor is connected to the lower right side of the fixed box through the second connecting pipe. When the air compressor is started, high-pressure air is sent into the fixed box through the second connecting pipe and blown out through the through hole, so that the bottom of the rubber plate is separated from the lower inner wall of the lower mold frame, making it easy to demold and remove.

[0014] The beneficial effects of this utility model are:

[0015] 1. The auxiliary cooling component can assist in cooling the raw material after plastic forming, thereby improving production efficiency. The auxiliary demolding component can also be used to deliver high-pressure air to detach the bottom of the rubber sheet from the inner wall of the lower mold frame, making it easier to demold and remove. This solves the problem that common plastic molds used in rubber sheet production lack auxiliary cooling structures, which leads to a long time required for cooling after the rubber sheet is molded. At the same time, the lack of auxiliary demolding structures makes it difficult to demold and remove the rubber sheet after production.

[0016] 2. Open the solenoid valve and start the delivery pump. External cooling water enters the delivery pump through the inlet pipe and then enters the heat exchange tube through the first connecting pipe to cool the material, accelerate its molding speed, and improve production efficiency.

[0017] 3. After the rubber sheet has completely solidified, the electric lifting rod drives the movable plate to descend. At this time, the block is disengaged from the through hole. The air compressor is started to send high-pressure air into the fixed box through the second connecting pipe and blow it out through the through hole, so that the bottom of the rubber sheet is disengaged from the inner wall of the lower mold frame, making it easy to demold and remove.

The air compressor 806 is started, and high-pressure air is sent into the fixed box 801 through the second connecting pipe 807 and blown out through the through hole, so that the bottom of the rubber sheet disengages from the lower inner wall of the lower mold frame 1, making it easy to demold and remove.
