Device for moulding thermoplastic containers by blowing

Abstract

The invention discloses a device for molding a thermoplastic container by blowing. The device comprises a base for supporting the mounting of other components, a molding part, an opening and closing component, two pairs of sliding rods, a reciprocating part and a driving part, the molding part comprises two modules, two air delivery pipes and a plurality of universal wheels, matched mold cavities are formed in the faces, close to each other, of the two modules correspondingly, the opening and closing component comprises two guide rails, two pairs of supporting plates and two pairs of sliding rods, the two guide rails are symmetrically and fixedly installed above the base through four supports, sliding openings are horizontally formed in the upper surfaces of the two guide rails, the two pairs of supporting plates are symmetrically and fixedly installed on the side faces of the four modules correspondingly, the two pairs of sliding rods are vertically and fixedly installed on the lower surfaces of the four supporting plates correspondingly and are slidably installed in the two sliding openings correspondingly, the reciprocating part is used for driving the four modules to be opened and closed in a reciprocating manner, and the driving part is used for driving the reciprocating part to operate. The two groups of molding parts work alternately, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of molding, in particular to a device for molding thermoplastic containers by blowing. Background technique [0002] Thermoplastic container is a kind of material that can be processed by thermoplastic, and it is formed by water blowing in the mold. It is widely used in liquid storage. It has the advantages of low cost and long service life. When the container is manufactured, the injection molding device The plastic material is introduced into the mold, and then the gas is injected to make the container. [0003] Existing molding devices usually only have one set of molds to work when manufacturing containers. The molds are combined to complete the extrusion of plastic materials, and then inject gas to complete the manufacture of containers. Open the mold here and take out the container. Such a mold, One working process can only complete the manufacture of one container, which greatly reduces production ef...
