Description

Technical Field

[0001] The present application relates to the technical field of thermal conductive silicone processing, and in particular to a mold for making a thermal conductive silicone sheet. Background Art

[0002] Thermally conductive silicone sheet is a kind of thermal conductive medium material synthesized by special process with silicone as base material and various auxiliary materials such as metal oxides. In the industry, it is also called thermal conductive silicone pad, thermal conductive silicone sheet, soft thermal conductive pad, thermal conductive silicone gasket, etc. It is specially designed for the design of transferring heat through gaps. It can fill the gaps and complete the heat transfer between the heating part and the heat dissipation part. It is an excellent thermal conductive filling material. In the production process, after the raw materials are mixed and stirred, they need to be rolled and cut, that is, the stirred materials are made into solid thermal conductive silicone sheets, and the materials are pressed into corresponding thickness and width by upper and lower rollers. After accelerated curing in the oven, the rear section is cut into regular size 320×320mm, and finally stamped into a specific shape according to the customer's drawings using a mold. After this process, the shipment inspection is carried out, and then the packaging can be arranged for shipment.

[0003] The size of the thermally conductive silicone sheet processed by the existing mold for stamping and making thermally conductive silicone sheets is usually fixed. If thermally conductive silicone sheets of other sizes need to be processed, the mold needs to be replaced, which is cumbersome in the operation process and requires a whole set of molds of different sizes, which increases the cost of use and maintenance. Therefore, in view of the above problems, a mold for making thermally conductive silicone sheets is proposed. Utility Model Content

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A mold for making a thermally conductive silicone sheet comprises an upper mold plate and a lower mold plate, wherein a guide member is connected between the upper mold plate and the lower mold plate, wherein a centrally arranged fixed longitudinal knife group is fixedly installed on the lower end surface of the upper mold plate, wherein L-shaped slide grooves are provided on the left and right sides of the upper mold plate, wherein a plurality of movable transverse knives are slidably provided in the L-shaped slide grooves, wherein the movable transverse knife comprises a sliding end piece slidably provided in the L-shaped slide grooves, wherein a bottom plate is fixedly provided on the upper end surface of the sliding end piece, wherein a centrally arranged transverse punching knife is fixedly provided on the upper end surface of the bottom plate, wherein a plurality of notches are provided on the transverse punching knife.

[0007] By adopting the above technical solution, the distance between adjacent movable transverse knives can be changed by pushing the movable transverse knife to make it slide, thereby changing the size of the punching area formed by the movable transverse knife and the fixed longitudinal knife group, and finally the punched thermal conductive silicone sheet can have different sizes to meet different production needs. In particular, the size of the punching area can be adjusted by increasing or decreasing the number of movable transverse knives, making the size adjustment operation very flexible.

[0008] As a preferred technical solution of the present application, the fixed longitudinal knife group includes a connecting plate, and three symmetrically arranged longitudinal punching knives are fixedly mounted on the upper end surface of the connecting plate. The longitudinal punching knives are arranged in the groove, and the connecting plate is fixedly connected to the upper template by mounting bolts.

[0009] By adopting the above technical solution, the thermally conductive silicone sheet can be punched out by the combined operation of the longitudinal punching knife and the transverse punching knife, so that the processed thermally conductive silicone sheet is a regular rectangular sheet.

[0010] As a preferred technical solution of the present application, the tip of the longitudinal punching knife and the tip of the transverse punching knife are on the same horizontal plane.

[0011] By adopting the above technical solution, it can be ensured that the longitudinal punching knife and the transverse punching knife can synchronously complete the transverse and longitudinal punching of the original sheet material.

[0012] As a preferred technical solution of the present application, a centrally arranged sliding rod is fixedly provided on the outer side surface of the sliding end piece, the sliding rod is slidably arranged in the L-shaped sliding groove, and a threaded fastening nut is sleeved on the end of the sliding rod.

[0013] By adopting the above technical solution, after the position adjustment of the transverse punching knife is completed, the fastening nut can be tightened, and the position of the sliding rod can be fixed by the friction between the fastening nut and the side of the upper template, thereby fixing the position of the transverse punching knife, thereby avoiding the sliding of the transverse punching knife to cause dimensional changes and affect the punching effect.

[0014] As a preferred technical solution of the present application, the guide member includes a guide cylinder and a guide rod, wherein the guide cylinder is fixedly arranged at the four corners of the lower end surface of the upper template, the guide rod is fixedly arranged at the four corners of the upper end surface of the lower template, and the upper part of the guide rod is slidably arranged in the guide cylinder.

[0015] By adopting the above technical solution, the guide rod can slide in the guide cylinder so that the upper template and the lower template can always remain aligned when approaching or moving away from each other, thereby enabling the longitudinal punching knife and the transverse punching knife to always move in the specified direction without deviation, thereby ensuring the punching effect.

[0016] As a preferred technical solution of the present application, a pad is clamped on the upper end surface of the lower template via a guide rod, and the pad is a plate structure of hard rubber with a smooth surface.

[0017] By adopting the above technical solution, the cutter heads of the longitudinal punching knife and the transverse punching knife can be protected.

[0018] The beneficial effects of the present application are as follows: the spacing between adjacent movable transverse knives can be changed by pushing the movable transverse knife to make it slide, thereby changing the size of the punching area formed by the movable transverse knife and the fixed longitudinal knife group, and finally the punched thermal conductive silicone sheet can have different sizes to meet different production needs. In particular, the size of the punching area can be adjusted by increasing or decreasing the number of movable transverse knives, making the size adjustment operation very flexible.
