Description
Technical Field
The utility model relates to a mold manufacturing technical field, in particular to cold runner injection mold.
Background
The die is a tool for making a blank into a finished piece with a specific shape and size under the action of external force, and is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy piece pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The silica gel mold is special mold glue for making handicraft, and the silica gel has the features of high temperature resistance, high corrosion resistance, high tear resistance and high simulation precision. For example, silica gel covers, silica gel tableware, silica gel molds, silica gel buttons, etc., and liquid silica gel is mainly used for extrusion molded products, such as silica gel nipples, silica gel tubes, etc.
The nipple is usually formed by injection molding of silica gel, and when the nipple is actually produced, the silica gel liquid is cooled and needs to be heated to be solidified, so that when the nipple is heated, the silica gel liquid is easy to solidify in an injection channel due to temperature change in the injection channel in contact with an injection molding cavity, and the injection molding efficiency is influenced.
