Description

Technical Field

[0001] This utility model relates to the field of rubber test piece technology, and in particular to a fluororubber sheet mold. Background Technology

[0002] Fluororubber vulcanization is a crucial step in the production of fluororubber products, directly affecting the quality and performance of the products. The vulcanization process includes mixing and vulcanization molding. Before mixing, rectangular test pieces need to be prepared in advance using fluororubber sheet molds to test the correctness of the formula and process.

[0003] The test cavity and template of existing fluororubber sheet molds are mostly integrated. When testing fluororubber of different thicknesses, the mold needs to be changed frequently, which is inconvenient.

[0004] The molds removed from the vulcanizing machine are extremely hot and require testers to wear protective gloves to remove them. The contact surfaces of the existing fluororubber sheet molds are too flat, making it inconvenient to open the upper template while wearing protective gloves. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art that rubber test pieces cannot test fluororubber of different thicknesses and that it is inconvenient to open the upper template when wearing protective gloves, and to propose a fluororubber sheet mold.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fluororubber sheet mold includes a lower template and an upper template. The sidewalls of the templates are provided with a handle, a locking groove, and an elliptical semi-groove. Limiting protrusions are provided at the four corners of the surface of the lower template. A test piece cavity is opened in the center of the lower template. An installation plate is fixedly connected inside the test piece cavity. A lifting assembly is provided on the top of the installation plate. A locking assembly is provided on one side of the lifting assembly. The lower template is engaged with the upper template by the limiting protrusions.

[0008] Preferably, a limiting slot is provided on the bottom surface of the upper template at the location corresponding to the limiting protrusion.

[0009] Preferably, a main rotating sleeve is fixedly installed at the center of the mounting plate, and auxiliary rotating sleeves are provided at the four corners of the surface of the mounting plate.

[0010] Preferably, the lifting assembly includes a gear and multiple gear sleeves. An operating shaft is fixedly installed at the bottom of the gear. The operating shaft is rotatably connected to the main rotating sleeve. A rocker arm is fixedly installed at one end of the operating shaft through the main rotating sleeve.

[0011] Preferably, the bottom of the gear sleeve is rotatably connected to the auxiliary rotating sleeve, the inner wall of the gear sleeve is threaded, and the gear sleeve meshes with the gear.

[0012] Preferably, the inner wall of the toothed sleeve is threaded with a lifting screw, and the top of the lifting screw is fixedly connected with a lifting plate.

[0013] Preferably, the locking assembly includes a locking rack located on one side of the gear and meshing with the gear, and a plurality of slide rods fixedly connected to the other side of the rack. A handle is fixedly connected to one side of the slide rods that passes through the lower template, and the handle is located in the locking groove.

[0014] Preferably, a plurality of return springs are provided around the sliding rod between the locking rack and the inner wall of the lower template.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting an elliptical semi-groove, this utility model provides a larger force point when the mold is closed, allowing testers to easily open the upper template through the elliptical semi-groove while wearing protective gloves.

[0017] 2. This utility model, by setting up a lifting component, rotates the rocker arm counterclockwise to drive the gear to rotate in the main rotating sleeve, and the gear drives the gear sleeve to rotate synchronously in the auxiliary rotating sleeve. The rotation of the gear sleeve drives the lifting screw and the lifting plate to rise slowly. Similarly, rotating the rocker arm clockwise can drive the lifting plate to fall slowly, thereby realizing the function of adjusting the depth of the test piece cavity, thus supporting the testing of sheets of different thicknesses.

[0018] 3. This utility model achieves a self-locking effect by setting a locking component, in which the elastic force of the return spring pushes the locking rack to engage the gear. When adjustment is needed, the handle is pulled from the locking groove by hand to disengage the locking rack from the gear, thereby releasing the lock. When the adjustment reaches the appropriate depth, the pulling is released, and the locking component resets and locks the gear under the elastic force of the return spring, thus realizing the locking function.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-8 A fluororubber sheet mold includes a lower template 1 and an upper template 2. The side wall of the lower template 1 is provided with a handle 3, a locking groove 4 and an elliptical semi-groove 5. Limiting protrusions 6 are provided at the four corners of the surface of the lower template 1. A test piece cavity 7 is opened in the center of the template. An installation plate 8 is fixedly connected in the test piece cavity 7. A lifting component is provided on the top of the installation plate 8. A locking component is provided on one side of the lifting component. The lower template 1 is engaged with the upper template 2 by the limiting protrusions 6.

[0030] Furthermore, a limiting slot 9 is provided on the bottom surface of the upper template 2 at the corresponding limiting protrusion 6 to facilitate quick alignment during assembly.

[0031] It should be noted that the depth of the limiting slot 9 is greater than the length of the limiting protrusion 6.

[0032] Furthermore, a main rotating sleeve 10 is fixedly installed at the center of the mounting plate 8, and auxiliary rotating sleeves 11 are provided at the four corners of the surface of the mounting plate 8.

[0033] Furthermore, the lifting assembly includes a gear 12 and multiple gear sleeves 13. An operating shaft 14 is fixedly installed at the bottom of the gear 12. The operating shaft 14 is rotatably connected to the main rotating sleeve 10. One end of the operating shaft 14 passes through the main rotating sleeve 10 and is fixedly installed with a rocker arm 15. The bottom of the gear sleeve 13 is rotatably connected to the auxiliary rotating sleeve 11. The inner wall of the gear sleeve 13 is threaded. The gear sleeve 13 meshes with the gear 12. The inner wall of the gear sleeve 13 is threadedly connected to a lifting screw 16. The top of the lifting screw 16 is fixedly connected to a lifting plate 17.

[0034] The further advantage of the above is that rotating the rocker arm 15 counterclockwise drives the gear 12 to rotate inside the main rotating sleeve 10. The gear 12 drives the gear sleeve 13 to rotate synchronously inside the auxiliary rotating sleeve 11. The rotation of the gear sleeve 13 drives the lifting screw 16 and the lifting plate 17 to rise slowly. Similarly, rotating the rocker arm 15 clockwise can drive the lifting plate 17 to fall slowly, thus achieving the function of adjusting the depth of the test piece cavity 7, thereby supporting the testing of sheets of different thicknesses.

[0035] Furthermore, the locking assembly includes a locking rack 18, which is located on one side of the gear 12 and meshes with the gear 12. A plurality of slide rods 19 are fixedly connected to the other side of the rack. A handle 20 is fixedly connected to one side of the slide rod 19 that passes through the lower template 1. The handle 20 is located in the locking groove 4. A plurality of return springs 21 are arranged around the slide rod 19 between the locking rack 18 and the inner wall of the lower template 1.

[0036] The further advantage of the above is that the elastic force of the return spring 21 pushes the locking rack 18 to engage the gear 12, thereby achieving a self-locking effect. When adjustment is needed, the handle 20 is pulled by hand from the locking groove 4 to make the locking rack 18 disengage from the gear 12, thereby releasing the lock. When the adjustment is reached to a suitable height, the pulling is canceled, and the locking component resets and locks the gear 12 under the elastic force of the return spring 21, thus realizing the locking function.

[0037] When using this invention, the pull handle 20 inside the locking groove 4 is held to disengage the locking rack 18 from the gear 12, thus releasing the lock. At the same time, the rocker arm 15 is rotated counterclockwise to drive the gear 12 to rotate inside the main rotating sleeve 10. The gear 12 drives the gear sleeve 13 to rotate synchronously inside the auxiliary rotating sleeve 11. When the gear sleeve 13 rotates, the lifting screw 16 and the lifting plate 17 are slowly raised through the threads on the inner wall. Similarly, rotating the rocker arm 15 clockwise can drive the lifting plate 17 to slowly descend, thus adjusting the depth of the test piece cavity 7. After adjusting to the appropriate depth, the pull is released. Under the elastic force of the return spring 21, the locking component resets and locks the gear 12. After the test piece formula is placed in, the mold is quickly assembled by aligning the limiting protrusion 6 with the limiting slot 9.

[0038] After the film is produced, the testers can easily open the upper template 2 through the elliptical half-groove 5 while wearing protective gloves, achieving the effect of easy use.

[0039] 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.
