Problems solved by technology

However, due to the characteristics of liquid silicone itself, and the traditional process is mostly based on liquid injection molding, its development cycle is long, the cost is high, and it is inconvenient to operate in some product processes.
As a result, flow properties are better than water in some cases, resulting in difficult handling during overmolding

Abstract

The invention aims to provide an earphone rubber-coating forming mould structure. According to the technical scheme, the earphone rubber-coating forming mould structure is composed of a lower mould plate, a middle mould plate and un upper mould plate; the lower mould plate is provided with lower mould positioning columns, lower mould positioning holes and lower mould forming moulds; the middle mould plate is provided with forming mould holes and middle mould positioning holes; the upper mould plate is provided with upper mould positioning columns, upper mould positioning holes and upper mouldforming moulds; and overflow grooves are further formed in the outer sides of all the forming mould holes and can prevent rubber from overflowing, so that formed products are more attractive. The flow-diving rubber-coating jig is simple in structure, the product forming stability is higher through the three-body closing type design mode, the rubber overflowing problem of the products after demoulding of the products can be prevented through the vertical flow-diving design, operation is safer and more environmentally friendly, and the quality and accuracy of the products are greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical processing molds, in particular to an earphone overmolding mold structure. Background technique [0002] With the development of society, liquid silicone has good fluidity, fast vulcanization, safety and environmental protection, and can fully meet the requirements of food grade, and liquid silicone has excellent transparency, tear strength, resilience, anti-yellowing, thermal stability High resistance, water resistance, good air permeability, heat aging resistance and weather resistance, moderate viscosity, easy to operate, high transparency of the product, you can see whether there are defects such as bubbles in the casting material in the mold, the linear shrinkage rate is very small, and the replica It is widely used in many fields due to its many advantages such as precise size. However, due to the characteristics of liquid silicone itself, and the traditional process is mostly based on liquid inje...
