Mold opening device of blow molding machine

Abstract

The invention discloses a mold opening device of a blow molding machine. The mold opening device comprises a base and two movable templates arranged on the base in left-right symmetry. The two opposite faces of the movable templates are both installing faces. The installing faces are provided with template grooves for installing a blowing mold. The groove bottoms of the template grooves are provided with installing holes. The positions, located on the surfaces of the movable templates, of the upper ends of the template grooves are provided with plastic entering half grooves. The upper surfaceof the base is provided with two slide bases which can slide to the inside or outside at the same time at the same speed. The two movable templates are rotationally installed on the left slide base and the right slide base through bearings correspondingly. The corresponding blow molding templates can be installed in the template grooves, no complete detachment is needed during type changing, and type changing can be realized only by rotating the movable templates; and the movable templates can have a deceleration effect during rotating, the rotating angle of the movable templates can be more conveniently controlled, and precision is improved.

Description

technical field [0001] The invention belongs to the technical field of blow molding machines, and in particular relates to a mold opening device of a blow molding machine. Background technique [0002] Blow molding machine: 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 force blown out by the machine to make a product. Plastic template, after the blow molding process is completed, the blow molding template is opened to take out the material. When the model needs to be changed, the blow molding template needs to be disassembled and replaced with a new blow molding template. Generally, manual replacement is required. Because the blow molding template is heavy, The replacement process is complicated, takes a lot of time, and is prone to safety accidents. Therefore, there is an urgent need for a blow molding machine mold opening device that can solve the above problems. Contents of the inven...
