Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an insulating film hot pressing mold. Background Art

[0002] Compression molding is a molding method in which the composite material is first placed into an open compression mold. The mold is closed and pressure is applied to force the material into contact with all areas of the mold, while heat and pressure are maintained until the material solidifies. This process is capable of producing parts that vary in length, thickness, and complexity. The objects it produces are also very strong, making it an attractive process for many different industries. Thermoset composites are the most common type of material used in compression molding;

[0003] The bus is a relay station on the motherboard that collects all the data and transmits it. Generally speaking, the system will install various interface cards through the bus and transmit various data to the devices connected to the interface cards. The existing bus insulation film needs to use a hot press mold during production. After the hot press mold is pressed, when the upper mold and the lower mold are separated, the hot press machine is easy to lift the upper mold together, causing the mold or product to be pulled and damaged, and due to the unstable adsorption force, the upper mold is easy to fall and cause damage to the product and personnel.

[0004] The existing patent (publication number: CN218776978U) insulating film hot pressing mold, through the provided clamping block, can be stored in the groove during the mold closing and hot pressing process, without affecting the hot pressing molding effect, and when demolding, it is ejected by the reset of the spring. At the same time, the clamping block will squeeze the cavity during the ejection process, so that the gas in the cavity will be ejected from the air jet hole, thereby preventing the insulating film from adhering to the upper mold, which has the beneficial effect of facilitating demolding.

[0005] The existing patent provides a solution to the above problem, but during use, after the air jet hole demoulds the local insulating film, air will continue to flow out of the air jet hole, resulting in insufficient air pressure in the remaining air jet holes, and thus only the local insulating film can be demoulded. Summary of the invention

[0006] The utility model aims to provide an insulating film hot pressing mold, which can solve the problem that after the local insulating film is demoulded, air will continue to flow out of the air jet hole, resulting in insufficient air pressure in the remaining air jet holes, and thus only the local insulating film can be demoulded.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an insulating film hot pressing mold, comprising an upper mold and a lower mold, a driving structure is fixedly installed on the top of the upper mold, a pushing mechanism is arranged on one side of the upper mold, the pushing mechanism comprises a support plate fixed to the outer surface of one side of the upper mold, a sealing cylinder is fixedly installed on the surface of the bottom of the support plate, an air inlet groove is provided on the side of the sealing cylinder close to one end of the support plate, and a pushing spring is fixedly installed inside the sealing cylinder close to one end of the support plate, an air supply disk is fixedly installed on one end of the pushing spring, a reciprocating rod is fixedly installed on the side of the air supply disk away from the support plate, a fixed plate is fixedly installed on the outer surface of the lower mold and located below the support plate, a connecting groove is provided inside the upper mold, and a pushing groove is provided inside the upper mold, a pushing block is slidably connected inside the pushing groove, a reset spring is fixedly installed on the surface of the pushing block close to one end of the connecting groove, a fixed disk is fixedly installed on one end of the reset spring, an air supply pipe is fixedly installed on the bottom of the sealing cylinder, one end of the air supply pipe is fixedly connected to the outer surface of the upper mold, and the air supply pipe and the connecting groove are connected to each other.

[0008] Preferably, the fixing disk is of hollow design, and the outer surface of the fixing disk is fixedly connected to the inner surface of the pushing groove.

[0009] Preferably, a one-way valve is fixedly installed inside the air supply disk, and the surface of the air supply disk is slidably connected to the inner surface of the sealing cylinder.

[0010] Preferably, one end of the reciprocating rod passes through the bottom of the sealing cylinder and extends to the inside of the sealing cylinder, and the outer surface of the reciprocating rod is slidably connected to the sealing cylinder.

[0011] Preferably, a plurality of the pushing grooves are provided, and the plurality of pushing grooves are evenly distributed on the outer surface of the bottom of the upper mold.

[0012] Preferably, the communicating groove and the pushing groove are communicated with each other.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By arranging a plurality of pushing blocks, after the upper mold and the lower mold are separated, the pushing spring pushes the air supply disk, so that the air supply disk squeezes the gas inside the sealing tube into the connecting groove, and then the gas flows into the pushing groove from the connecting groove to push the pushing block inside the pushing groove, so that the pushing block pushes the insulating film, thereby completing the separation between the insulating film and the upper mold, avoiding the existing demolding method using exhaust holes, in which air is continuously discharged after the local insulating film is demolded, resulting in insufficient air pressure, and only partial demolding of the insulating film can be completed, which requires manual secondary demolding.

A restoring rod 46, a fixing plate 47 is fixedly installed on the outer surface of the lower mold 2 and located below the support plate 41, a connecting groove 48 is opened inside the upper mold 1, and a pushing groove 49 is opened inside the upper mold 1, and a pushing block 410 is slidably connected inside the pushing groove 49, and a return spring 411 is fixedly installed on the surface of the push block 410 close to one end of the connecting groove 48, and a fixing plate 412 is fixedly installed on one end of the return spring 411, and an air supply pipe 413 is fixedly installed on the bottom of the sealing cylinder 42, one end of the air supply pipe 413 is fixedly connected to the outer surface of the upper mold 1, and the air supply pipe 413 and the connecting groove 48 are connected to each other.

[0025] In the present application, the movement of the air supply disk 45 and the reciprocating rod 46 is described with reference to the sealing tube 42, and when the upper mold 1 and the lower mold 2 are close to each other, the fixed plate 47 will squeeze the reciprocating rod 46, so that the reciprocating rod 46 drives the air supply disk 45 to reset, causing the push groove 49 to lose the push of the gas, and then the reset spring 411 pulls the push block 410 to reset.

[0026] The fixing plate 412 is hollow in design, and the outer surface of the fixing plate 412 is fixedly connected to the inner surface of the pushing groove 49 .

[0027] The hollow design of the fixing plate 412 can avoid the problem that the fixing plate 412 affects the air flow.

[0028] A one-way valve is fixedly installed inside the air supply disk 45 , and the surface of the air supply disk 45 is slidably connected to the inner surface of the sealing cylinder 42 .

[0029] The one-way valve is used to allow the external gas to supplement the gas inside the sealing tube 42 when the gas supply disk 45 moves in the direction of the push spring 44 .

[0030] One end of the reciprocating rod 46 passes through the bottom of the sealing cylinder 42 and extends to the inside of the sealing cylinder 42 , and the outer surface of the reciprocating rod 46 is slidably connected to the sealing cylinder 42 .

[0031] There are a plurality of push grooves 49 , and the plurality of push grooves 49 are evenly distributed on the outer surface of the bottom of the upper mold 1 .

[0032] The communicating groove 48 and the pushing groove 49 are communicated with each other.

[0033] Working principle:

[0034] When the insulating film is hot-pressed, the upper mold 1 is driven down by the driving structure 3, and the upper mold 1 and the lower mold 2 are closed by the cooperation of the positioning block and the positioning groove. When the hot pressing is completed, the upper mold 1 is driven to rise by the driving structure 3. In the process of rising, the upper mold 1 will drive the support plate 41 to move upward, and the upward movement of the support plate 41 will drive the sealing cylinder 42 to move upward, and the upward movement of the sealing cylinder 42 will drive the reciprocating rod 46 to move upward, so that the reciprocating rod 46 is no longer restricted by the fixed plate 47, and then the push spring 44 pushes the air supply disk 45, so that the air supply disk 45 squeezes the gas inside the sealing cylinder 42, and then the gas enters the interior of the connecting groove 48 through the air supply pipe 413, and then enters the interior of the pushing groove 49 from the interior of the connecting groove 48, so that the gas pushes the pushing block 410 inside the pushing groove 49, so that the pushing block 410 pushes the insulating film, completing the separation of the insulating film and the upper mold 1.

[0035] By setting a plurality of pushing blocks 410, after the upper mold 1 and the lower mold 2 are separated, the pushing spring 44 pushes the air supply disk 45, so that the air supply disk 45 squeezes the gas inside the sealing tube 42 into the connecting groove 48, and then the gas flows into the pushing groove 49 from the connecting groove 48 to push the pushing block 410 inside the pushing groove 49, so that the pushing block 410 pushes the insulating film, thereby completing the separation between the insulating film and the upper mold 1, avoiding the existing demolding method using exhaust holes, after the local insulating film is demolded, the air is continuously discharged, resulting in insufficient air pressure, and only the local demolding of the insulating film can be completed, which requires manual secondary demolding.
