[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] A foam mold for easy installation of foam core molds includes a box body 1 and a perforated pressure plate 2. A movable plate 3 is slidably arranged at the bottom of the box body 1. A module 4 is fixedly installed in the middle of the movable plate 3. The module 4 is square. Vertical plates 5 are arranged around the module 4. Templates 6 are fixedly installed on the side of each vertical plate 5 near the module 4. Symmetrical mounting blocks 7 are fixedly installed on the side of the movable plate 3. There are three sets of mounting blocks 7. A movable rod 8 is rotatably arranged between every two mounting blocks 7. One vertical plate 5 is fixedly installed to the movable plate 3. The bottom edges of the other three vertical plates 5 are fixedly installed to the movable rods 8 respectively. A stop block 9 is fixedly installed on the side of each of the other three vertical plates 5. A torsion spring 10 is arranged in each mounting block 7. The two ends of the torsion spring 10 are fixedly installed to the mounting block 7 and the movable rod 8 respectively. The bottom edge of the template 6 is rounded.

[0027] In this foam mold, module 4 and the four edge templates 6 form a complete mold, and the perforated pressure plate 2 is used for foam injection molding of the mold.

[0028] When installing the foam core mold, the operator pulls the vertical plate 5 fixed to the movable plate 3 on one side. The vertical plate 5 drives the movable plate 3 and all its components to slide outward along the bottom of the box 1. During the outward movement of the movable plate 3, the torsion spring 10 in the mounting block 7 provides an outward deflection force, causing the other three sets of vertical plates 5 to rotate outward through the movable rod 8. Because the bottom edge of the template 6 is set as an arc edge, the template 6 will also deflect and open during the outward deflection of the vertical plate 5. Then, the foam core mold is placed on the module 4. After the core mold is placed, the operator pushes the templates 6 on both sides to come closer to each other and fit the sides of the foam core mold. Then, the operator pushes the movable plate 3 to move into the box 1, so that the innermost template 6 is automatically fitted to the side of the foam core mold by the force. The abutment block 9 is used to abut against the inner wall of the box 1 to ensure the stability of the template 6. Then, the mold is foamed through the pressure plate 2 with the perforation.

[0029] This foam mold allows for easy installation of the foam core mold inside the foam mold, making it convenient, time-saving, labor-saving, and improving foam injection molding efficiency. It is highly practical.

[0030] A limiting strip 11 is fixedly installed on the side of the movable plate 3, and a limiting channel 12 is opened on the inner side of the box body 1. The limiting strip 11 is slidably arranged on the limiting channel 12, and the size of the limiting strip 11 is adapted to the size of the limiting channel 12.

[0031] When the movable plate 3 slides inside the housing 1, the limiting strip 11 fixedly installed on the side of the movable plate 3 will slide within the limiting channel 12 opened on the inside of the housing 1. Since the size of the limiting strip 11 and the size of the limiting channel 12 are matched, the limiting strip 11 and the limiting channel 12 can guide the sliding of the movable plate 3, preventing the movable plate 3 from deviating during the sliding process. During the foam injection molding process, the cooperation of the limiting strip 11 and the limiting channel 12 can prevent the movable plate 3 from shaking, thereby improving the overall stability of the mold during foam injection molding, and also ensuring the stability of the movable plate 3 sliding on the housing 1.

[0032] Damping is provided between the movable plate 3 and the box 1, and damping is provided between the limiting strip 11 and the limiting channel 12;

[0033] During the foam injection molding process, the damping provided between the movable plate 3 and the box 1 can suppress the vibration and displacement of the movable plate 3 and prevent the movable plate 3 from shaking unnecessarily due to the injection pressure. At the same time, the damping provided between the limiting strip 11 and the limiting channel 12 further increases the resistance when the movable plate 3 slides. The two work together to effectively reduce the possibility of the movable plate 3 moving during the injection molding process, thereby further improving the overall stability of the mold during foam injection molding.

[0034] The size of the lower pressure plate 2 with the leakage hole is adapted to the size of the opening of the box body 1, and the size of the nozzle of the lower pressure plate 2 with the size of the module 4 is adapted to the size of the module 4.

[0035] During foam injection molding, the perforated pressure plate 2 covers the opening of the box 1. Since the size of the perforated pressure plate 2 is compatible with the size of the opening of the box 1, it can fit tightly, effectively ensuring the sealing during the foam injection molding process. The size of the nozzle on the perforated pressure plate 2 is compatible with the size of the module 4, which allows the foam raw material to be accurately injected into the mold cavity formed by the module 4 and the template 6, ensuring the accuracy of foam injection molding and improving product quality.

[0036] A handle 13 is fixedly installed on the side of the vertical plate 5 on one side;

[0037] When it is necessary to install or operate the foam mold, the operator can pull the handle 13 fixedly installed on the side of one vertical plate 5. The handle 13 drives the vertical plate 5 to move, which in turn drives the movable plate 3 and its module 4, other vertical plates 5 and other components to be pulled out of the box 1 together, which facilitates the operator to operate inside the mold and improves the convenience of operation.

[0038] Working principle:

[0039] In this foam mold, module 4 and the four edge templates 6 form a complete mold, and the perforated pressure plate 2 is used for foam injection molding of the mold.

[0040] When installing the foam core mold, the operator pulls the vertical plate 5 fixed to the movable plate 3 on one side. The vertical plate 5 drives the movable plate 3 and all its components to slide outward along the bottom of the box 1. During the outward movement of the movable plate 3, the torsion spring 10 in the mounting block 7 provides an outward deflection force, causing the other three sets of vertical plates 5 to rotate outward through the movable rod 8. Because the bottom edge of the template 6 is set as an arc edge, the template 6 will also deflect and open during the outward deflection of the vertical plate 5. Then, the foam core mold is placed on the module 4. After the core mold is placed, the operator pushes the templates 6 on both sides to come closer to each other and fit the sides of the foam core mold. Then, the operator pushes the movable plate 3 to move into the box 1, so that the innermost template 6 is automatically fitted to the side of the foam core mold by the force. The abutment block 9 is used to abut against the inner wall of the box 1 to ensure the stability of the template 6. Then, the mold is foamed through the pressure plate 2 with the perforation.

[0041] This foam mold allows for easy installation of the foam core mold inside the foam mold, making it convenient, time-saving, labor-saving, and improving foam injection molding efficiency. It is highly practical.

[0042] in,

[0043] When the movable plate 3 slides inside the box 1, the limiting strip 11 fixedly installed on the side of the movable plate 3 will slide within the limiting channel 12 opened inside the box 1. Since the size of the limiting strip 11 and the size of the limiting channel 12 are matched, the limiting strip 11 and the limiting channel 12 can guide the sliding of the movable plate 3 and prevent the movable plate 3 from deviating during the sliding process. During the foam injection molding process, the cooperation of the limiting strip 11 and the limiting channel 12 can prevent the movable plate 3 from shaking, thereby improving the overall stability of the mold during foam injection molding, and also ensuring the stability of the movable plate 3 sliding on the box 1.

[0044] During the foam injection molding process, the damping provided between the movable plate 3 and the box 1 can suppress the vibration and displacement of the movable plate 3 and prevent the movable plate 3 from shaking unnecessarily due to the injection pressure. At the same time, the damping provided between the limit strip 11 and the limit channel 12 further increases the resistance when the movable plate 3 slides. The two work together to effectively reduce the possibility of the movable plate 3 moving during the injection molding process, thereby further improving the overall stability of the mold during foam injection molding.

[0045] During foam injection molding, the perforated pressure plate 2 covers the opening of the box 1. Since the size of the perforated pressure plate 2 is compatible with the size of the opening of the box 1, it can fit tightly, effectively ensuring the sealing during the foam injection molding process. The size of the nozzle on the perforated pressure plate 2 is compatible with the size of the module 4, which allows the foam raw material to be accurately injected into the mold cavity formed by the module 4 and the template 6, ensuring the accuracy of foam injection molding and improving product quality.

[0046] When it is necessary to install or operate the foam mold, the operator can pull the handle 13 fixedly installed on the side of one vertical plate 5. The handle 13 drives the vertical plate 5 to move, which in turn drives the movable plate 3 and its module 4, other vertical plates 5 and other components to be pulled out of the box 1 together, which facilitates the operator to operate inside the mold and improves the convenience of operation.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
