Liquid-state silicone mold

Abstract

The invention discloses a liquid-state silicone mold. The liquid-state silicone mold comprises a diversion component, a pressure plate, a cooling component, a sealing needle and a spring, wherein the diversion component comprises an external diversion body and an internal diversion body, the external diversion body sleeves the internal diversion body, and at least one diversion channel is formed between the external diversion body and the internal diversion body; a pressure plate rubber inlet is formed on the pressure plate; the cooling component sleeves the diversion component and is provided with a cooling channel, and a cooling rubber outlet is formed at the bottom of the cooling component and is communicated with the diversion channel; the sealing needle movably passes through the internal diversion body and extends into the cooling rubber outlet; the spring is arranged on the sealing needle in a sleeving manner. Compared with the prior art, the liquid-state silicone mold has the advantages that the structure is simple, the operation is convenient, huge external equipment is not needed, and thus the cost is reduced; no remnant is left on the surface of a formed product, so that secondary processing is not needed, human resources are saved, and a waste of raw material is avoided; in a halt state, silicone is not solidified in the mold, and the surface of the formed product is free of wiredrawing.

Description

technical field [0001] The invention belongs to the field of molds, in particular to a liquid silicone mold. Background technique [0002] Due to the special physical properties of liquid silicone, including low viscosity, unique rheological properties, obvious shear thinning and high thermal expansion system. In the prior art, most of the feed nozzles of liquid silicone molds adopt the following two types. One is the open type, which requires secondary processing and the production process is complicated because the feed point remains after molding; the other is the needle valve type, which relies on a huge external Mechanisms, such as the control of oil, gas, and circuits of cylinders or oil cylinders, require a lot of accessories and accessories, and the cost is relatively high. [0003] Therefore, there is an urgent need for a liquid silicone mold with simple processing and low cost. Contents of the invention [0004] In order to solve the above technical problems, t...
