Abstract

The invention relates to the field of blow molding machinery, in particular to a blow molding device. In the blow molding device, the width of an annular extrusion molding channel A can be regulated by rotating a hand-screw, so that blow molding is performed on blow molding pieces in different thickness; opening and closing of two rectangular frames can be controlled through a cylinder rotary rod,and dies on the two rectangular frames can both be changed, so that shaping can be performed on a soft blow molding material in different shapes; and stretching of the two rectangular frames can be controlled through the cylinder rotary rod, so that demolding of the blow molding pieces is facilitated. In the blow molding device, parts are convenient to disassemble, and thus damaged parts are convenient to repair; a rectangular block is provided with a cylinder cavity and a conical cavity which share one axis, the cylinder cavity is communicated with the conical cavity, the diameter of the lower end of the conical cavity is smaller than the diameter of the upper end of the conical cavity, the rectangular block is provided with a feeding hole communicated with the cylinder cavity, the feeding pipe is fixedly connected to the feeding hole on the rectangular block, a sealing ring I is adhered to the upper end of the rectangular block and is arranged at the edge of the upper end of the cylinder cavity.

Description

technical field [0001] The invention relates to the field of blow molding machinery, more specifically a blow molding device. Background technique [0002] The application number is CN201810046237.1, a blow molding device. The invention discloses a blow molding device, which belongs to the field of blow molding machinery and includes an extruder 1, a die head 2, a mandrel 3, and a variable capacitor cylinder. 4 and compression mold structure 7; beneficial effect: the present invention is simple in structure, easy to operate, it carries out blow molding first, blows out the mold base of general shape, and then mold base is extruded, and the weight of the product made by the present invention is adjustable, and intensity higher. This patent is not easy to be disassembled and repaired, and different molds cannot be replaced for blow molding of different shapes. Contents of the invention [0003] The invention provides a blow molding device, the beneficial effect of which is...
