Desktop plate blow-molding apparatus

Abstract

The invention discloses a desktop plate blow-molding apparatus, which comprises a blow molding port, a blow molding die-locking machine, and a blow molding die fixed in the blow molding die-locking machine, the blowing die comprises a left half die and a right half die, an oval discharge hatch is arranged at the blow molding port, the raw materials can be extruded from the discharge hatch in an annular curtain shape, the left half die or the right half die comprise mold core plates, more than two independent fixed plates are arranged at outboard of the mold core plate, a support column is arranged between each fixed plate and the mold core plate, a top seal clamping plate capable of automatically sealing the top of the raw materials is arranged over the blow molding die, and a bottom seal clamping plate capable of automatically sealing the bottom of the raw materials is arranged below the blow molding die. The desktop plate blow-molding apparatus has the advantages that raw material waste amount is less, automatic sealing equipment can be used for substituting artificial sealing, work efficiency is increased, and die sticking problem of the products can be solved.

Description

technical field [0001] The invention relates to a desktop board blow molding device. Background technique [0002] Nowadays, many portable household items are made of plastic products, such as folding dining tables, chairs, etc., and the main tabletops of such dining tables are relatively large, so injection molding requires high equipment requirements and requires large-scale equipment. Therefore, the semi-finished products of this type of large panels are basically extruded after blow molding, that is, the raw materials are extruded in a continuous strip shape, and then extruded by the mold after extrusion. Now there are The main problems are: 1. Since the panel of this type of semi-finished product is relatively large, and its shape is plate-shaped, while most of the traditional blow molding mouths are circular, so the raw material is not well controlled when it is extruded from a circular shape to a plate shape. , often produce waste of raw materials; 2, because the raw...

Problems solved by technology

[0002] Nowadays, many portable household items are made of plastic products, such as folding dining tables, chairs, etc., and the main tabletops of such dining tables are relatively large, so injection molding requires high equipment requirements and requires large-scale equipment. Therefore, the semi-finished products of this type of large panels are basically extruded after blow molding, that is, the raw materials are extruded in a continuous strip shape, and then extruded by the mold after extrusion. Now there are The main problems are: 1. Since the panel of this type of semi-finished product is relatively large, and its shape is plate-shaped, while most of the traditional blow molding mouths are circular, so the raw material is not well controlled when it is extruded from a circular shape to a plate shape. , often produce waste of raw materials; 2, because the raw material is extruded downward in the form of a circular strip, the thickness of the strip-shaped raw material is relatively thin, and it is easy to flutter, and the raw material band is easy to stick when fluttering, so generally before extrusion molding, the operator must Manually seal the ring-shaped bottom to make it into a pocket shape, let the air blown out of the blow molding mouth fill the inner cavity of the sealed raw material belt, and squeeze it after the inner cavity is bulged. The defect is that the manual sealing efficiency is too slow, and the sealing The quality is not good; 3. This type of product is easy to stick to the mold after extrusion, that is, the product is easy to stick to the surface of the core after the mold is separated, and it is troublesome for the operator to take it
