[0002] Liquid silicone is abbreviated as LSR in English. It is a product that is favored by consumers and manufacturers. Liquid silicone is made of silicone products. It has good elasticity, waterproof and moisture resistance, and is resistant to acid, alkali and other chemical substances. , the overmolding of most seals can achieve the advantages of one-time molding, no waste and automation during production and processing. Using injection molding, large quantities, rapid vulcanization, and repetitive mechanical production, the product performance is better Excellent thermal stability, cold resistance, excellent electrical insulation performance, and no toxic substances will be produced when burned, so it is used in the production design of health products, automobiles, baby products, medical products, diving products, kitchen utensils and seals, etc. It has become an irreplaceable material; it is also a common processing method in LSR and metal parts lagging operations, and the existing operation mode and method for metal parts lagging are all using thimble positioning or clamping positioning methods, and the positioning position cannot be wrapped with silicone , it is impossible to realize the full encapsulation of the functional surface of the metal parts, and it is also impossible to achieve the effect of uniform encapsulation; in summary, it is necessary to develop and design a set of encapsulation feed molds with more comprehensive functions to solve the problem that the metal parts cannot achieve comprehensive encapsulation. The problem of lagging and uniform lagging is to improve the quality and yield of metal parts lagging
