DETAILED DESCRIPTION

[0025] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0026] Reference Figure 1-Figure 5 The embodiment of the present disclosure provides a molding die 001, including a lower template 8 and an upper template 1, wherein the lower template 8 has a cavity for pressurized and heated molding, and it should be noted that the cavity is opened on the top surface of the lower template 8. The lower template 8 has a heating channel, and the side of the lower template 8 has a pressure relief channel connected to the cavity, wherein the pressure relief channel is isolated from the heating channel, and the pressure relief channel discharges the high-pressure gas generated during the pressurized molding process to the body; illustratively, the pressure relief channel adopts an exhaust hole structure, and the exhaust hole structure is connected to the aforementioned cavity. The upper template 1 covers the lower template 8 and can mold the plate 6 to be molded into a fixed structure.

[0027] Exemplarily, the pressure relief channel adopts a hole structure which is arranged in the lower template 8 along the horizontal direction and discharged from the side of the lower template 8. The embodiment of the present disclosure does not limit the hole structure, which depends on the actual application needs.

[0028] The molding mold 001 of the embodiment of the present disclosure can discharge the high-temperature gas formed in the mold cavity to the outside during the heating molding process, and during the pressure relief and exhaust process, the upper mold 1 and the lower mold 8 always remain in the mold closing state, which can improve the structural quality of the molded panel in this process.

[0029] In the actual production process, during the heating and molding process, high-temperature gas is generated in the cavity within a certain period of time. After the upper template 1 and the lower template 8 are molded together, in the initial state, the pressure relief channel cannot be directly connected to the outside of the body. However, after the high-temperature gas is generated, the pressure relief channel is directly connected to the outside of the body through the corresponding structure in the molding mold 001, thereby ensuring the discharge of high-temperature gas and not affecting the product quality of the molding process.

[0030] Specifically, the molding die 001 of the disclosed embodiment further includes a lower die support assembly, which is connected to the lower die plate 8, and includes an ejector pin 9. In the mold closing state, the ejector pin 9 extends from the bottom to the top into the lower die plate 8, and is configured to extend into the pressure relief channel and cut off its cross-sectional channel during the vertical movement from the bottom to the top, and is adjusted to at least partially detach from the pressure relief channel to make it communicate with the outside of the body. It can be seen that the movement of the ejector pin 9 can play a role in adjusting from blocking the pressure relief channel to opening the pressure relief channel.

[0031] In order to realize the movement of the ejector pin 9 relative to the pressure relief channel in the mold closing state, the lower mold support assembly of the embodiment of the present disclosure further includes an ejector oil cylinder 20, a top plate 17 and a bottom plate 19. The ejector oil cylinder 20 at least partially extends into the bottom mold plate 8, and the push rod of the ejector oil cylinder 20 extends downward through the top plate 17 to connect with the bottom plate 19. The bottom plate 19 is located below the top plate 17. In the initial state, a safety gap is reserved between the bottom plate 19 and the top plate 17. One end of the ejector pin 9 is connected to the top plate 17, and the other end of the ejector pin 9 extends into the lower mold plate 8 and can move along the lower mold plate 8. In this way, the ejector oil cylinder 20 can drive the top plate 17 and the ejector pin 9 to move toward the bottom plate 19. This process is the action of the ejector pin 9 to open the pressure relief channel. When the ejector oil cylinder drives the top plate 17 and the ejector pin 9 to move toward the upper mold plate 1, this process is the action of the ejector pin 9 to block the pressure relief channel.

[0032] Considering that a safety gap is reserved in advance between the top plate 17 and the bottom plate 19, the safety gap serves as the movable range of the top plate 17 relative to the bottom plate 19. In the initial state, a relatively stable interval needs to be maintained between the top plate 17 and the bottom plate 19. Therefore, the lower mold support assembly of the embodiment of the present disclosure also includes a limit slider combination structure, and the limit slider combination structure includes a vertically arranged top plate retraction height control block 18 and a horizontally arranged top plate retraction sliding block 15, which are arranged to slide along an inclined surface, and the top plate retraction height control block 18 at least partially protrudes from the top plate 17. When the top plate retraction sliding block 15 moves toward the outside of the body, the ejection cylinder 20 is configured to drive the top plate 17 and the ejector pin 9 to move toward the bottom plate 19. In this way, when the top plate retraction height control block 18 and the top plate retraction sliding block 15 maintain a completely fitted state along the inclined surfaces of the two, the top plate retraction sliding block 15 can block the movement of the top plate 17, and when the top plate retraction sliding block 15 moves in the direction away from the top plate retraction height control block 18, the top plate 17 can move along the direction of the top plate retraction height control block 18.

[0033] Further considering the source of kinetic energy for the movement of the top plate retraction sliding block 15, the limit sliding block combination structure of the disclosed embodiment also includes a transversely arranged top plate retraction control cylinder 16, the push rod of the top plate retraction control cylinder 16 is connected to the top plate retraction sliding block 15, and the top plate retraction control cylinder 16 is used to drive the top plate retraction sliding block 15 to move toward or away from the top plate retraction height control block 18.

[0034] Exemplarily, a top plate retraction groove 13 is provided at the side position of the top surface, a top plate retraction height control block 18 is installed in the top plate retraction groove 13, and a top plate retraction sliding block 15 can extend into and out of the top plate retraction groove 13 in the lateral direction.

[0035] Furthermore, in order to achieve stable mold clamping of the upper mold plate 1 and the lower mold plate 8, the molding die 001 of the disclosed embodiment further includes a guide post 2, an upper mold guide block 3 and a lower mold guide block 4, wherein the guide post 2 is installed at the corner position of the upper mold plate 1 and at least partially protrudes from the bottom surface of the upper mold plate 1, and the lower mold plate 8 is provided with a guide hole corresponding to the guide post 2, the upper mold guide block 3 is installed at least partially protruding from the bottom surface of the upper mold plate 1, and the lower mold guide block 4 is installed at least partially protruding from the top surface of the lower mold plate 8, and the upper mold guide block 3 and the lower mold guide block 4 cooperate to engage and limit. In this way, the accurate mold clamping position of the upper mold plate 1 and the lower mold plate 8 can be ensured.

[0036] Specifically, the molding die 001 further comprises a height adjustment block 7, which is mounted on the top surface of the lower die plate and can adjust the flatness of the mold surface.

[0037] In addition, considering the friction in the mold closing action and the sliding slider action, the molding die 001 of the disclosed embodiment further includes a first wear-resistant block 5 and a second wear-resistant block 14, wherein the first wear-resistant block 5 is arranged between the upper mold guide block 3 and the lower mold guide block 4, and the second wear-resistant block 14 is arranged between the top plate retreat sliding block 15 and the top plate retreat height control block 18. In this way, the service life of the molding die 001 can be improved.

[0038] Furthermore, considering the movement accuracy and service life of the molding die 001 , two groups of limit slider combination structures are provided in the embodiment of the present disclosure, and the two groups of limit slider combination structures are matched and provided on both sides of the molding die 001 .

[0039] In summary, the main functional structure of the molding die 001 can ensure the completion of the blocking and opening of the ejector pin 9 relative to the pressure relief channel. Here, other structural components of the molding die 001 are supplemented, wherein the lower mold support assembly also includes a support member, and the support member includes a plurality of square irons 12, and the plurality of square irons 12 are supported between the lower mold plate 8 and the bottom plate 19, and enclose a space for assembling a plurality of ejector pins 9, and an assembly space for the ejector cylinder 20 is reserved between at least part of two adjacent square irons 12. The molding die 001 also includes a support column 11, and a plurality of support columns 11 are provided, and each support column 11 is connected between the lower mold plate 8 and the ejector plate 17. In this way, the stable application of the entire mold can be fully realized. In addition, the lower mold support assembly also includes a return pin 10, and the return pin 10 can protect other ejector pins and fix the height of other ejector pins.
