Technical Field

[0001] This utility model belongs to the technical field of tools for testing release agents, and in particular relates to a special mold for testing release agents. Background Technology

[0002] Release agents are functional chemical agents used to prevent materials from sticking to molds. They are widely used in casting, plastic molding, rubber processing, and composite material manufacturing. During the product trial molding stage, a suitable release agent needs to be selected based on the material. In existing technologies, the release agent is sprayed into the production mold to test its release performance. However, this testing method has the following drawbacks: the production mold has a complex structure, making it inconvenient to clean and replace the release agent, thus affecting the efficiency of the trial molding. Utility Model Content

[0003] The purpose of this invention is to provide a special mold for testing release agents, aiming to solve the technical problems in the prior art.

[0004] To achieve the above objectives, the present invention provides a mold for testing release agents, comprising a lower mold plate and an upper mold plate. The top of the lower mold plate is recessed with several material cavities, and the sides of the material cavities are provided with overflow grooves. Lower inserts are detachably stacked in the material cavities. The lower inserts have a lower abutment surface acting on the bottom of the material, and the lower abutment surface is sprayed with release agent. The upper mold plate has an assembly hole corresponding to the material cavities. An upper insert is detachably fixed in the assembly hole. The upper insert has an upper abutment surface acting on the top of the material, and the upper abutment surface is sprayed with release agent.

[0005] Optionally, there are four material cavities arranged in a rectangular array on top of the lower template.

[0030] In one embodiment of this utility model, such as Figures 1-4As shown, a mold for testing release agent is provided, including a lower mold plate 1 and an upper mold plate 2. The top of the lower mold plate 1 is recessed with several material cavities 11, and the sides of the material cavities 11 are provided with overflow grooves 12. Lower inserts 13 are detachably stacked in the material cavities 11. The lower inserts 13 have a lower abutment surface 131 that acts on the bottom of the material. The lower abutment surface 131 is sprayed with release agent. The upper mold plate 2 has an assembly hole 21 corresponding to the material cavities 11. An upper insert 22 is detachably fixed in the assembly hole 21. The upper insert 22 has an upper abutment surface 221 that acts on the top of the material. The upper abutment surface 221 is sprayed with release agent. The testing steps in this embodiment are as follows: First, a release agent is applied to the lower abutment surface 131 of the lower insert 13, and it is placed into the material cavity 11 of the lower mold plate 1. Then, the material product is placed into the material cavity 11. Finally, a release agent is applied to the upper abutment surface 221 of the upper insert 22, and the upper mold plate 2 is provided with the pressure to achieve mold closing with the lower mold plate 1 to simulate the scenario of material contact and forming of the insert during the production process, thereby completing the release performance test of the release agent. When the release performance is poor, the upper insert 22 and the lower insert 13 are disassembled, cleaned, and another release agent is applied to obtain a release agent with better release performance. This embodiment can provide testing for the selection of release agents for metal stamping parts, plastic parts, and rubber parts. During the test, the material product needs to be made into a sheet-like body that matches the shape of the material cavity 11. The top surface of the sheet-like body contacts and fits the upper abutment surface 221, and the bottom surface contacts and fits the lower abutment surface 131. Furthermore, the upper template 2, upper insert 22, lower template 1 and lower insert 13 are all made of metal and have a chromium plating on their surfaces.

[0031] In one embodiment of this utility model, such as Figure 3 As shown, there are four cavities 11, which are arranged in a rectangular array on the top of the lower mold plate 1. Utilizing four cavities 11 in a single mold closing action improves testing efficiency.

[0032] In one embodiment of this utility model, such as Figure 3 As shown, the overflow trough 12 is cross-shaped, with its outer end penetrating the lower template 1 and its inner ends communicating with each other. The overflow trough 12 provides deformable space for the material product under pressure.

[0033] In one embodiment of this utility model, such as Figure 3 As shown, it also includes connecting ribs 132 that correspond one-to-one with the overflow grooves 12. The connecting ribs 132 located on the inner side can connect adjacent lower inserts 13. The four lower inserts 13 are connected into a whole by the connecting ribs 132, which facilitates the batch assembly and disassembly of the lower inserts 13.

[0034] In one embodiment of this utility model, such as Figure 3As shown, the connecting ribs located on the outer side extend outward to form a handle. The handle is formed on the outer side of the lower template 1 to facilitate the insertion and removal of the lower insert 13.

[0035] In one embodiment of this utility model, such as Figure 3 As shown, it also includes a demolding opening 14, which is recessed in the top of the lower template 1. This provides space for the upper template 2 to open, and during testing, the top surface of the upper template 2 abuts against the output shaft of the external pressure device, requiring manual lifting of the upper template 2 for mold opening.

[0036] In one embodiment of this utility model, such as Figure 3 As shown, the top edge of the material cavity 11 is provided with a chamfer 111 to facilitate the insertion of the lower insert 13.

[0037] In one embodiment of this utility model, such as Figure 4 As shown, it also includes a tension block 23. The top end of the upper insert 22 passes through the mounting hole 21, and its end is threaded into the tension block 23. The upper insert 22 can be fixed or detached by tightening the tension block 23.

[0038] In one embodiment of this utility model, such as Figure 4 As shown, the tension block 23 is a hexagonal block. The upper insert 22 can be installed or removed by applying a hexagonal wrench to the tension block 23.

[0039] In one embodiment of this utility model, such as Figure 4 As shown, the top of the upper template 2 is recessed with a countersunk hole 24 arranged coaxially with the assembly hole 21. The tension block 23 is located in the countersunk hole 24 to provide a backing surface for the output shaft of the external pressure device.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
