Description

Technical Field

[0001] The utility model relates to the technical field related to rubber processing, in particular to an extrusion molding type rubber shaping mold. Background Technique

[0002] The main raw materials of rubber products are raw rubber, various compounding agents, as well as fiber and metal materials as skeleton materials. The basic production process of rubber products includes 6 basic processes: plasticating, mixing, calendering, extruding, molding, and vulcanizing. The rubber processing process is mainly a process of solving the contradiction between plasticity and elasticity. Through various processing means, elastic rubber is made into plasticated rubber with plasticity, and then various compounding agents are added to make semi-finished products. Then, through vulcanization, the semi-finished products with plasticity are made into rubber products with high elasticity and good physical and mechanical properties. Therefore, there is a particular need for an extrusion molding type rubber shaping mold.

[0003] However, in the existing extrusion molding type rubber shaping mold, during the use process, the upper mold fixture and the lower mold fixture cooperate to extrude and form rubber. During the process of making the rubber form, the amount of rubber raw material placed cannot be controlled, and the excessive rubber raw material cannot overflow, resulting in deviation in the thickness of the subsequent extrusion molding.

[0004] To solve the above problems, after retrieval, the patent with the publication number CN214447928U discloses a shaping mold for extrusion molding of vulcanized rubber. It is proposed in the text that "a shaping mold for extrusion molding of vulcanized rubber includes an upper mold fixture and a lower mold fixture for cooperating to extrude and vulcanize rubber into shape. The lower mold fixture includes a shaping module, on which a shaping groove for accommodating vulcanized rubber is opened, and an overflow groove communicating with the shaping groove is also opened on the shaping module. When the upper mold fixture and the lower mold fixture are pressed together, the excess vulcanized rubber raw material in the shaping groove can flow into the overflow groove for storage, and then the thickness of the formed experimental sample after taking out and cooling remains consistent". Although the excess raw material can overflow from the mold interior during the rubber shaping process through the overflow groove, after the shaping is completed, the raw material in the overflow groove is connected and shaped with the product, and manual cutting is required in the subsequent process, and qualified rubber products cannot be provided in this process.

[0005] In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: an extrusion molding type rubber shaping mold, including a lower mold 1, an upper mold 2 and a cutting mechanism 4. The upper side of the lower mold 1 is provided with the upper mold 2. One side of the surface of the lower mold 1 is fixedly connected with a limit rod 3. One side of the surface of the lower mold 1 is provided with the cutting mechanism 4. One side of the surface of the upper mold 2 is fixedly connected with a handle 5. One side of the surface of the upper mold 2 is provided with a limit hole 6. One side of the inner surface of the upper mold 2 is provided with an overflow groove 7;

[0023] The cutting mechanism 4 includes a support column 401, a movable groove 402, a limiting groove 403, a sleeve 404, a sliding rod 405, a return spring 406, a mounting plate 407, a wrench 408, a cutting knife 409 and a limiting strip 410. One side of the surface of the lower mold 1 is fixedly connected with the support column 401. An internal movable groove 402 is provided in the support column 401, and a limiting groove 403 is provided in the support column 401. The sleeve 404 is installed inside the movable groove 402. The sliding rod 405 is fitted inside the sleeve 404. The return spring 406 is sleeved on the surface of the sleeve 404. One end of the sliding rod 405 is fixedly connected with the mounting plate 407. One side of the surface of the mounting plate 407 is fixedly connected with the wrench 408. One end of the mounting plate 407 is installed with the cutting knife 409. One side of the surface of the mounting plate 407 is fixedly connected with the limiting strip 410. Through the settings of the support column 401, the movable groove 402, the limiting groove 403, the sleeve 404, the sliding rod 405, the return spring 406, the mounting plate 407, the wrench 408, the cutting knife 409 and the limiting strip 410, when in use, after the upper mold 2 is lifted and the rubber shaping is completed, the wrench 408 can be pulled. At this time, the wrench 408 drives the mounting plate 407 to move. Since the limiting strip 410 fixedly connected to one side of the surface of the mounting plate 407 is fitted inside the limiting groove 403, the mounting plate 407 moves along the direction in which the limiting strip 410 moves on the inner wall of the limiting groove 403. At this time, the sleeve 404 and the sliding rod 405 perform a mutual sliding movement, and the return spring 406 undergoes a tensile deformation. The mounting plate 407 drives the cutting knife 409 to move towards the lower mold 1. Since the cutting knife 409 is aligned with the top surface of the lower mold 1, the cutting knife 409 cuts the rubber shaped inside the overflow groove 7 to prevent the formed rubber from not meeting the standards.

[0024] Further, the limiting groove 403 is communicated with the movable groove 402. The limiting strip 410 is in the shape of a dovetail. The limiting strip 410 is fitted inside the limiting groove 403. Through the setting of the limiting strip 410, when in use, the limiting strip 410 is fitted inside the limiting groove 403, so that the moving direction of the mounting plate 407 can be limited.

[0025] Further, one end of the sleeve 404 is fixedly connected with the support column 401 inside the movable groove 402. The sleeve 404 and the sliding rod 405 form a mutual sliding structure. Through the settings of the sleeve 404 and the sliding rod 405, when in use, the sleeve 404 and the sliding rod 405 perform a mutual sliding movement, so that the return spring 406 can be limited on the basis of not affecting the compression and rebound deformation of the return spring 406.

[0026] Further, one end of the reset spring 406 is fixedly connected to the support column 401 inside the movable slot 402, and the other end of the reset spring 406 is fixedly connected to the mounting plate 407. Through the arrangement of the reset spring 406, when in use, when the acting force on the wrench 408 disappears, the reset spring 406 rebounds and deforms to drive the mounting plate 407 to return to its original position.

[0027] Further, the cutting knife 409 is aligned with the top surface of the lower mold 1. Through the arrangement of the cutting knife 409, when in use, the cutting knife 409 cuts the rubber shaped inside the overflow groove 7 to prevent the formed rubber from not meeting the standards.

[0028] Further, the limiting rod 3 and the limiting hole 6 are of matching sizes and are aligned with each other. Through the arrangement of the limiting rod 3 and the limiting hole 6, when in use, the limiting rod 3 and the limiting hole 6 can align the upper mold 2 directly above the lower mold 1.

[0029] Further, the overflow groove 7 is arranged at the side edge of the upper mold 2. Through the arrangement of the overflow groove 7, when in use, when the upper mold 2 presses the lower mold 1, the excess raw material inside the lower mold 1 can be removed from the inside of the lower mold 1 through the overflow groove 7.

[0030] Working principle: First, place the raw material inside the lower mold 1, then place the upper mold 2 above the lower mold 1, and at the same time ensure that the limiting hole 6 and the limiting rod 3 are aligned with each other. Then press the upper mold 2 to extrude the raw material. The excess raw material inside the lower mold 1 flows out through the overflow groove 7. After the shaping is completed, remove the upper mold 2, and then pull the wrench 408. At this time, the wrench 408 drives the mounting plate 407 to move. Since the limiting strip 410 fixedly connected to one side of the surface of the mounting plate 407 is fitted inside the limiting groove 403, the mounting plate 407 moves along the direction in which the limiting strip 410 moves on the inner wall of the limiting groove 403. At this time, the sleeve 404 and the sliding rod 405 slide relative to each other, and the reset spring 406 undergoes tensile deformation. The mounting plate 407 drives the cutting knife 409 to move towards the lower mold 1. Since the cutting knife 409 is aligned with the top surface of the lower mold 1, the cutting knife 409 cuts the rubber shaped inside the overflow groove 7 to prevent the formed rubber from not meeting the standards.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
