Cooling has a challenging and very important meaning in mold design, it is directly related to the size and quality of product output. Blow molds are generally cooled by circulating water cooling. The specific method is to arrange the cooling circuit by drilling on the mold, so that the circuit passes where the cooling is most needed. In order to better improve the quality and output, most molds are designed with several independent cooling zones. In the production of blow molds, the neck and bottom of the product need to dissipate the most heat, so the design must consider how to use the most effective method for cooling.
In order to allow gas to escape quickly during part blow molding, the mold must be vented. The most common and economical method of blow molding Mo Yao is surface exhaust. Deep blasting or texturing the mold cavity can also help vent gas.
The design of the positioning column of the reciprocating blow molding machine and the automatic blow molding machine can refer to the mold design of the injection molding machine.合 Angle.
The opening and closing of the molds of the multi-station rotary blow molding machine is not parallel, but the moving template rotates according to a fixed point to complete the opening and closing action. Only when the mold is closed, the moving template and the static template are parallel.
