Blow molding nozzle and blow molding machine

Abstract

The present invention disclosed a kind of blowing nozzle and blow molding machine, including the base, which is fixed with a fixed board and drive motor on the top of the base from left to right.The top of the rack, the top of the base is fixed with a fixed connection. The two separators are fixed with the bottom of the top plate from the bottom of the base. The present invention involves the field of blow molding machine technology.This blowing nozzle and blowing plastic formation machine. When the lower mold seat that is completed by blowing plastic needs to be sealed, start the rotor motor to drive the link rotation, so that the separators will slide out along the separator and seal with the seal plate.Seal the lower model and the upper mold seat, and the blowing cold air is sprayed evenly along the decentralized cooling mouth. It can quickly cool down the lower mold seat, and the cold air can form a cycle between the separators, which can greatly extend the cold air to greatly extend the cold air.The time of stay, the energy utilization rate is higher.

Description

technical field [0001] The invention relates to the technical field of blow molding machines, in particular to a blow molding nozzle and a blow molding machine. Background technique [0002] After the liquid plastic is sprayed out, the plastic body is blown and attached to a mold cavity of a certain shape by using the wind blown by the machine to make a product. This machine is called a blow molding machine. The plastic is melted and blown in the screw extruder. Quantitative extrusion, then molded through the mouth film, and then blown by the wind ring for cooling, and then pulled by a tractor at a certain speed, and wound by a winding machine into rolls, blow molding is also called hollow blow molding, a rapidly developing plastic The processing method is that the tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the split mold while it is hot, and compressed air is passed into the parison immediately after the mold is cl...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a blow molding nozzle and a blow molding machine, which solves the problem that it is too time-consuming to seal the blow-molded product during cooling, so it is directly sprayed with cold air. , but because the cold air blown out will soon overflow in the air, the utilization efficiency is low, thus causing a huge energy consumption problem
