Description

Technical Field

[0001] The utility model relates to the technical field of silicone molds, in particular to a universal zero-clamp silicone gasket mold. Background Art

[0002] During the injection molding process of silicone gaskets, there will be a clamping problem on the inner and outer sides of the gasket. This clamping problem not only affects the appearance of the gasket product, but also affects the installation of the silicone gasket.

[0003] In order to ensure that the produced silicone gaskets meet the requirements, after removing the product from the mold, it is usually necessary to perform a cleaning operation to make the inner and outer edges of the gasket smooth to meet the requirements of the production process.

[0004] However, the existing process requires an additional edge cleaning operation. At the same time, the silicone gasket taken out is soft in texture and is easily bent under force during edge cleaning, making the edge cleaning operation more difficult and resulting in the defect of complex silicone gasket production process.

[0005] Based on this, the utility model designs a universal zero-clamp silicone gasket mold to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a universal zero-clamp silicone gasket mold to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes an upper mold and a lower mold; an upper mold is provided on the upper mold, and a first cutter and a second cutter are fixedly arranged in the upper mold cavity, the first cutter is located on the inner side of the second cutter, an inner waste trough is provided on the side of the first cutter away from the upper mold cavity, and an outer waste trough is provided on the side of the second cutter away from the upper mold cavity; a lower mold is provided on the lower mold, and a forming table is fixedly arranged in the lower mold cavity; the upper mold cavity and the lower mold cavity are arranged in pairs in multiple groups.

[0008] By adopting the above technical solution, after the silicone raw material is placed in the lower cavity, the silicone gasket product is formed in the upper cavity and the lower cavity through extrusion of the upper mold and the lower mold. At the same time, when the upper mold and the lower mold are merged, the first cutter and the second cutter cut the clamp along the inner edge and the outer edge of the silicone gasket, so that the clamp falls into the inner waste trough and the outer waste trough after being cut off, so that the surface of the produced product meets the use requirements.

[0009] Preferably, a guide column is fixedly provided on the upper mold, a guide hole is opened on the lower mold, the guide column is slidably provided in the guide hole, and a plurality of guide columns are provided.

[0010] By adopting the above technical solution, the cooperation between the guide column and the guide hole helps the upper mold and the lower mold to extrude the silicone gasket, and the cooperation accuracy between each upper cavity and the lower cavity meets the requirements.

[0011] Preferably, a guide block is fixedly provided on the end of the guide column away from the upper mold.

[0012] By adopting the above technical solution, the provision of the guide block helps to align the guide column with the guide hole during mold closing.

[0013] Preferably, an overflow groove is provided on the upper mold.

[0014] By adopting the above technical solution, the overflow trough is set so that when the upper and lower molds are forming, excess raw materials can be temporarily stored in the overflow trough, avoiding waste material remaining on the fitting surface between the upper and lower molds, and preventing the upper and lower molds from insufficiently fitting and causing molding failure.

[0015] To sum up, the present application has the following beneficial technical effects: after the silicone raw material is placed in the lower cavity, the silicone gasket finished product is formed in the upper cavity and the lower cavity through extrusion of the upper mold and the lower mold. At the same time, when the upper mold and the lower mold are merged, the first cutter and the second cutter cut the clamp along the inner edge and outer edge of the silicone gasket, so that the clamp falls into the inner waste trough and the outer waste trough after being cut off, so that the surface of the produced product meets the use requirements, and has the advantage of simplifying the silicone gasket production process.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The following is combined with Figure 1 —4 Provide further details of this application.

[0025] A universal zero-grip silicone gasket mold comprises an upper mold 1 and a lower mold 2.

[0026] An upper mold 1 is provided with an upper mold cavity 3, in which a first cutter 4 and a second cutter 5 are fixedly arranged. The first cutter 4 is located on the inner side of the second cutter 5. An inner waste trough 6 is provided on the side of the first cutter 4 away from the upper mold cavity 3, and an outer waste trough 7 is provided on the side of the second cutter 5 away from the upper mold cavity 3; an overflow trough 8 is provided on the upper mold 1.

[0027] A lower cavity 9 is formed on the lower die 2 , and a forming table 10 is fixedly arranged in the lower cavity 9 ; multiple groups of upper cavities 3 and lower cavities 9 are arranged in pairs.

[0028] A guide post 11 is fixedly provided on the upper die 1 , and a guide block 12 is fixedly provided on the end of the guide post 11 away from the upper die 1 ; a guide hole 13 is opened on the lower die 2 , and the guide post 11 is slidably provided in the guide hole 13 , and a plurality of guide posts 11 are provided.

[0029] The working principle of this embodiment is as follows: the upper mold 1 and the lower mold 2 are respectively mounted on two working devices of the hydraulic press. When producing the silicone gasket 14, the silicone raw material is placed in the lower mold cavity 9 of the lower mold 2. The hydraulic press is then driven to operate, so that the two working devices drive the upper mold 1 and the lower mold 2 to move closer to each other. As the upper mold 1 and the lower mold 2 move closer to each other, the upper mold cavity 3 and the lower mold cavity 9 gradually squeeze the silicone raw material to form the silicone gasket 14, and gradually squeeze the excess material into the overflow trough 8. When the upper mold 1 and the lower mold 2 are completed, the first cutter 4 and the second cutter 5 come into contact with the forming table 10, and the clamps on the inner and outer edges of the silicone gasket 14 are cut off, so that the clamps fall into the inner waste trough 6 and the outer waste trough 7, and the inner and outer edges of the formed silicone gasket 14 have smooth surfaces; then the upper mold 1 and the lower mold 2 are separated, and the silicone gasket 14 in the lower cavity 9 can be taken out, and after cleaning the clamps in the inner and outer waste troughs 6 and 7 and the waste in the overflow trough 8, the next extrusion molding can be carried out.

[0030] After the silicone raw material is placed in the lower mold cavity 9, the finished silicone gasket 14 is formed in the upper mold cavity 3 and the lower mold cavity 9 through extrusion of the upper mold 1 and the lower mold 2. At the same time, when the upper mold 1 and the lower mold 2 are merged, the first cutter 4 and the second cutter 5 cut the clamp along the inner edge and outer edge of the silicone gasket 14, so that the clamp falls into the inner waste trough 6 and the outer waste trough 7 after being cut off, so that the surface of the produced product meets the use requirements, which has the advantage of simplifying the production process of the silicone gasket 14.
