The cold hole has a diameter of about 8-10mm and a depth of about 6mm. To facilitate demoulding, the bottom of the demoulding rod is usually borne by the demoulding rod.The top of the demoulding rod shall be designed as a glyph hook or sinking groove so that the protruding part of the main channel can be pulled out smoothly when the demoulding is made.

 Parallel channel is the channel connecting the main channel and the multi-groove die cavity. In order for the melt to fill all the cavities at the same speed, the arrangement of the shunt device on the plastic mold should be symmetrical and equidistant. The shape and size of the shunt segment have an impact on the flow of the plastic melt, the demoulding of the product and the difficulty of mold manufacturing.

If the flow is equal, the resistance of the circular section is minimal. Because the cylindrical channel has a small specific surface area, which is not conducive to the cooling of the diversion channel, the diversion channel must be set on the two-half mold, the labor intensity is large, not easy to align. Therefore, commonly used trapezoidal or semicircular section divider, they are arranged with the demoulding rod on the half of the mold. The surface of the runner must be polished to reduce flow resistance and provide faster filling speeds. The size of the wheel depends on the type of plastic, the size and thickness of the product. For most thermoplastics, the cross-sectional width of the shunt does not exceed 8 mm, the size of the shunt can reach 10-12 mm, and the size of the shunt is 2-3 mm. On the premise of satisfying the requirements, minimize the cross-sectional area, increase the shunt and prolong the cooling time.
