A demoulding ejector rod 11 is fixedly installed at the front end, and the top of the demoulding ejector rod 11 passes through the support platform 2 and the lower mold 4. The lower mold 4 is installed on the top of the support platform 2 on the base 1 through the first mounting mechanism 8, which is convenient for disassembly and maintenance. A hydraulic cylinder 6 is installed on the rear support frame 5, and its bottom output end passes through the top rail 7 of the support frame 5 and is installed with the upper mold 9 through the second mounting mechanism 3, so that a stable installation is achieved and it is easy to replace. At the same time, the demoulding ejector rod 11 on the connecting frame 10 can eject the product after the stamping process is completed, so as to realize automatic demoulding without the need for an external structure, with high demoulding efficiency and convenient maintenance and repair. On the whole, the device performs well in mold installation, demoulding and maintenance, and can effectively improve the efficiency and convenience of automobile seat accessories processing.

[0024] refer to Figure 3The first mounting mechanism 8 includes a slide plate 31, which is slidably connected to the inner side of the top rail 7. Both ends of the slide plate 31 are fixedly connected to the limiting components 32. A support seat 33 is fixedly installed at the bottom of the slide plate 31. The bottom of the support platform 2 is fixedly connected to the top of the upper mold 9 body. The slide plate 31 in the first mounting mechanism 8 can slide flexibly inside the top rail 7, and the limiting components 32 at both ends play a limiting and fixing role, thereby ensuring the stability of the installation of the upper mold 9. At the same time, through the cooperation between the slide plate 31 and the support seat 33, a reliable connection between the upper mold 9 and the support platform 2 is achieved, so that the upper mold 9 can remain in a stable state during installation and use, which facilitates the disassembly and assembly of the upper mold 9, is beneficial to subsequent maintenance and replacement work, and improves the convenience and efficiency of the entire device in mold installation.

[0025] refer to Figure 3 The limit assembly 32 includes side rails 321, and the side rails 321 are fixedly installed at both ends of the slide plate 31. The inside of the side rails 321 is fixedly connected to the limit springs 322, and the top of the limit springs 322 is fixedly installed with the limit blocks 323. The inner sides of the limit blocks 323 are fit-connected with the two sides of the side rails 321. The side rails 321 are fixed at both ends of the slide plate 31, providing an installation basis for other components. The limit springs 322 inside the side rails 321 give the limit blocks 323 elastic support, so that the limit blocks 323 can be stably fit-connected with the two sides of the side rails 321. This design ensures that when the upper mold 9 needs to be fixed, the limit blocks 323 can reliably play a limiting role, prevent the slide plate 31 from moving easily, and ensure the firmness of the installation of the upper mold 9; and when the upper mold 9 needs to be disassembled and assembled, it can be achieved more conveniently by operating the limit blocks 323.

[0026] refer to Figure 3 The bottom of the limit block 323 is fixedly connected with a connecting rod 324, and the outer end of the connecting rod 324 passes through the side rail 321 and is fixedly connected with an anti-slip handle 325. The limit block 323 is connected to the anti-slip handle 325 at the outer end, so that the operator can easily control the movement of the connecting rod 324 by holding the anti-slip handle 325, thereby driving the limit block 323 to perform corresponding actions. When the mold needs to be disassembled and assembled, the position of the limit block 323 can be easily adjusted by pulling the anti-slip handle 325, thereby realizing rapid installation or disassembly of the mold. This design increases the convenience and controllability of the operation.

[0027] refer to Figure 3The overall cross-sectional shape of the limit block 323 is set in a right-angled triangle, and the inclined surface of the limit block 323 is set at the upper end of the outer side. The limit block 323 is set to a right-angled triangle with the inclined surface located at the upper end of the outer side. When the upper mold 9 needs to be installed, during the process of inserting the slide plate 31 into the side rail 321, the right-angled side can better achieve stable limit engagement and ensure the firmness of the installation. During disassembly, the limit block 323 is moved downward by pulling the anti-slip handle 325 to drive the connecting rod 324. Due to the presence of the inclined surface, the slide plate 31 can be relatively more smoothly pulled out of the side rail 321, reducing friction resistance and making the disassembly and assembly process more convenient and labor-saving. This special shape design cleverly takes into account both the stability of installation and the convenience of operation.

[0028] refer to Figure 4 The second mounting mechanism 3 includes a mounting groove 81 and a slide groove 82. The mounting groove 81 is opened in the middle of the top of the support platform 2, and the slide groove 82 is opened in the middle of the upper front end of the support platform 2. Both ends of the inner side of the slide groove 82 are fixedly connected with telescopic springs 83, and the outer end of the telescopic spring 83 is fixedly installed with a movable block 84. The outer end of the movable block 84 is fixedly connected with a limiting pin 85. The four corners of the mounting groove 81 are provided with movable grooves 86. The inner side of the movable groove 86 is slidably connected with a displacement block 87. The inner side of the displacement block 87 is fixedly connected to the lower mold 4. The inner sides of the two groups of displacement blocks 87 located at the front end are provided with limiting holes 88. The outer end of the limit pin 85 is inserted into the inner side of the limit hole 88, and the telescopic spring 83 in the slide groove 82 provides elastic support for the movable block 84. The limit pin 85 on the movable block 84 cooperates with the limit hole 88 on the displacement block 87 to achieve the limit fixation of the lower mold 4. When the lower mold 4 needs to be disassembled and assembled, the limit pin 85 can be flexibly separated or combined with the limit hole 88 through the movable operation of the movable block 84 and the displacement block 87, so that the installation and disassembly of the lower mold 4 can be completed conveniently and quickly. This structural design not only ensures the stability of the lower mold 4 after installation, but also makes the disassembly process simple and efficient, and improves the convenience and flexibility of the device in handling the lower mold 4.

[0029] refer to Figure 4 A push plate 89 is fixedly installed on the outer side of the displacement block 87, and the outer end of the push plate 89 is set to be an arc shape. The push plate 89 facilitates the operator to directly push the displacement block 87 to realize the installation and disassembly related actions of the lower mold 4. The outer end of the push plate 89 is set to be an arc shape. On the one hand, it can reduce the accidental injuries that may be caused to the operator during the operation, making the operation safer; on the other hand, the arc-shaped design is visually smoother and more beautiful, and is more in line with ergonomic principles, allowing the operator to feel more comfortable when pushing.

[0030] Principle and advantages of use: By setting up the hydraulic cylinder 6 and the demoulding ejector 11 to cooperate, the device can be used to place the product between the inner sides of the upper mold 9 and the lower mold 4.

The upper mold 9 and the lower mold 4 squeeze each other to cause the product to deform and complete the stamping process. After the stamping process is completed, the hydraulic cylinder 6 can be started to move upward. During the upward movement of the hydraulic cylinder 6, the connecting frame 10 can be adaptively driven to move upward, and the upward movement of the connecting frame 10 can drive the demoulding ejector The rod 11 moves upward, and the demoulding ejector rod 11 penetrates and supports the lower mold 4, so that the product inside the lower mold 4 can be ejected, so that the device can realize rapid molding and demoulding of the product by operating a hydraulic cylinder 6, so that the product can be automatically demoulded without the need for an external structure for demoulding, and the overall demoulding efficiency is high, which is convenient for rapid disassembly, maintenance and repair. In addition, during the demoulding process, the demoulding top cover can be adaptively telescopic with the top rail 7, and the demoulding top cover can be adaptively moved downward during the molding process to avoid affecting the demoulding. The entire device can be quickly demoulded, which can improve the overall convenience of the device.

When the upper mold 9 needs to be installed, the slide plate 31 can be reinstalled and inserted into the inside of the side rail 321, and the limit spring 322 can be reset to drive the limit block 323 to move upward, and the limit block 323 moves upward to contact the two ends of the limit slide plate 31 and the side rail 321, so that the upper mold 9 can be quickly clamped and installed, so that the overall device can quickly disassemble and inspect the upper mold 9;

[0032] By setting up the second mounting mechanism 3, when the lower mold 4 needs to be replaced during use of the device, the push plate 89 can be pressed to move inward, and the push plate 89 can move inward to drive the movable block 84 to move inside the slide groove 82 and the movable groove 86, and the movable block 84 can drive the limit pin 85 to move inward, and the limit pin 85 can move inward to disengage from the limit hole 88, and the displacement block 87 inside the movable groove 86 loses its limit, so the displacement block 87 can be pulled out from the inside of the movable groove 86, and the disassembly and assembly of the lower mold 4 can be completed, and the lower mold 4 needs to be installed. When the movable block 84 is in the state of being moved, the limit pin 85 can be moved outwards by releasing the push plate 89 and then inserting the displacement block 87 into the movable groove 86. The lower mold 4 is installed on the inner side of the displacement block 87, so that the lower mold 4 of the device can be stably installed, and the convenience of disassembly and assembly of the lower mold 4 of the device as a whole can be improved.
