Description

Technical Field

[0001] The utility model relates to the technical field of rubber product production, in particular to a mold for producing rubber film pressed products. Background Technique

[0002] Rubber pressed products refer to preforms that are made to flow into the mold cavity by means of pressure through various rubber molding presses. Then, after a period of time under specific temperature and pressure, the rubber material undergoes a chemical reaction (the molecules crosslink from linear to network), thereby obtaining products with applicable properties.

[0003] When the existing mold is in use, due to the need for a certain temperature and pressure, the products after pressing are likely to adhere to the inside of the mold, which is not convenient for demolding, and the products are also likely to be damaged due to adhesion during demolding.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1, the present utility model provides a technical solution for a mold used in the production of rubber film pressed products: A mold for the production of rubber film pressed products includes a base 1 and a top plate 20. A number of guide rods 9 are connected between the base 1 and the top plate 20. A bottom plate mold groove 5 is opened in the center of the top wall surface of the base 1. A bottom plate mold 4 is installed in the bottom plate mold groove 5. The bottom plate mold groove 5 and the bottom plate mold 4 are connected by a number of bottom plate mold fixing bolts 3. A bottom plate mold fixing bolt groove 2 is opened on the base 1 at the position of the bottom plate mold fixing bolts 3. An electric heater 6 is fixedly installed in the base 1 and at the center of the bottom plate mold groove 5. A heat conducting plate 7 is fixedly installed inside the bottom plate mold 4. A mold groove 8 is opened on the top wall surface of the bottom plate mold 4. A hydraulic device 19 is fixedly installed in the center of the bottom wall surface of the top plate 20. The telescopic end of the hydraulic device 19 is connected to a sub-pressing plate 18. A pressing block 11 is fixedly installed at the bottom of the sub-pressing plate 18. Guide rod movable sleeves 10 are sleeved on the guide rods 9 around the pressing block 11. A water cooler 16 is fixedly installed in the center of the bottom wall surface of the pressing block 11. A top plate mold 14 is provided at the bottom of the pressing block 11. The top plate mold 14 and the pressing block 11 are fixedly connected by a top plate mold fixing bolt 13. A top plate mold fixing bolt hole 12 is opened on the pressing block 11 at the position of the top plate mold fixing bolts 13. A cooling plate 15 is installed on the top wall surface of the top plate mold 14.

[0016] Further, both between the cooling plate 15 and the water cooler 16 and between the bottom plate mold groove 5 and the heat conducting plate 7 are tightly attached and connected by a high-temperature heat conducting medium.

[0017] Further, the water cooler 16 is externally connected to a water cooling pipe 17, and the water cooling pipe 17 is connected to a circulating cold water system.

[0018] Further, the top plate mold 14 and the bottom plate mold 4 cooperate with each other.

[0019] Further, the bottom plate mold 4 is tightly attached to the bottom plate mold groove 5, and the top plate mold 14 and the water cooling pipe 17 are tightly attached.

[0020] Embodiment: When this device is in use, the supporting top plate mold 14 and bottom plate mold 4 are respectively fixedly installed on the bottom plate mold groove 5 and the pressing block 11 through the bottom plate mold fixing bolts 3 and the top plate mold fixing bolts 13.

[0021] When installing the top plate mold 14 and the bottom plate mold 4, it is necessary to coat the surfaces of the water cooler 16 and the electric heater 6 with a full layer of high-temperature heat conducting medium. During installation, the cooling plate 15 and the water cooler 16 are closely attached, and the heat conducting plate 7 and the electric heater 6 are closely attached to increase the heat conductivity.

[0022] During processing, the rubber is placed in the mold groove 8, and then the hydraulic device 19 is started to press the pressing block 11 downward. After the electric heater 6 is heated, the heat is transferred to the heat conducting plate 7 through the medium for heating. The heat conducting plate 7 transfers the heat to the mold groove 8 to heat the rubber inside. At the same time, it receives the pressure from the top plate mold 14, causing the rubber material to undergo a chemical reaction and the molecules to crosslink from linear to network, thus obtaining a product with applicable properties.

[0023] After pressing is completed, the electric heater 6 stops heating first. At the same time, cold water is injected into the water cooler 16 through the water cooling pipe 17 for cooling. The heat at the processing part of the top plate mold 14 enters the water cooler 16 through the cooling plate 15, and the heat is circulated away to achieve cooling.

[0024] After cooling, the top plate mold 14 shrinks to a certain extent, making it more convenient for demolding. After processing, the product remains in the mold groove 8, which is convenient for taking out.

[0025] After cooling for a period of time, the pressing block 11 is lifted by the hydraulic device 19 for demolding, and the product can be taken out from the mold groove 8.

[0026] If different products need to be processed, the corresponding bottom plate mold 4 and top plate mold 14 can be replaced, which is convenient and fast.

[0027] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
