Abstract

A plastic bottle pulling and disengaging device for a blow molding machine comprises a template, a mould, an opening and closing mechanism and a blow molding mechanism, wherein the template, the mould and the opening and closing mechanism are mounted on a machine frame, and the mould is provided with an automatic bottle disengaging mechanism. The plastic bottle pulling and disengaging device is characterized in that the automatic bottle disengaging mechanism is a pulling and disengaging device for the mouth of a plastic bottle and comprises a draw hook connected to the machine frame; and the draw hook is in contact with the mouth of the formed plastic bottle and is provided with a hoisting device. The utility model adopts the technical proposal that the draw hook is mounted on the machine frame and is in contact with the mouth of the formed plastic bottle, so that the plastic bottle attached into the mould is pulled out, separated, and inverted downwards by means of the self gravity of the plastic bottle without taking the bottle with hands, thereby the automatic bottle disengagement is achieved, the production efficiency is high, the labor intensity is low, and the two hands are prevented from being injured by the mould.

Description

Stretch blow machine plastic bottle pull device

Technical field

The utility model relates to plastic draw-blow machine, particularly relates to the device that pulls of stretch blow machine plastic bottle, belongs to the plastics machinery field.

Background technology

When adopting injection moulding and stretch blow two-step method processing plastic hollow container, at first plastic raw materials such as PET are annotated and made bottle base by injection machine, bottle base needs the heater post bake, again the bottle base after the heating is put into the stretch blow of stretch blow machine mould and become bottle, prior art can be combined in heater and stretch blow machine on the machine, bottle base on the heater after the heating can enter in the stretch blow machine mould automatically, be called full-automatic stretch blow machine, also can unify heater and stretch blow unit, but the bottle base on the heater after the heating is taken in the stretch blow machine mould by manual, by manual bottle after the stretch blow is taken out from mould again, be called semi-automatic stretch blow machine.The bottle that takes off of semi-automatic stretch blow machine takes out the moulding bottle in the stretch blow machine mould with hand owing to operating personnel, and the shortcoming of its existence is: the one, and labor intensity of operating staff is very big, and is very busy, and production efficiency is low; The 2nd, get in the bottle careless both hands and run over and injure by mould easily, there is industrial injury hidden danger.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide the moulding bottle in a kind of stretch blow machine mould manually to deviate from automatically, the production efficiency height, and labour intensity is low, avoids the device that pulls of stretch blow machine plastic bottle that both hands are run over and injure by mould.

The technical scheme that pulls device of the utility model stretch blow machine plastic bottle is: comprise rack-mounted template, mould and clasp mould mechanism; and Stretch and Blow Mechanism; described mould is equipped with automatic bottle removing mechanism; it is characterized in that described automatic bottle removing mechanism is the device that pulls of plastics spout; comprise the drag hook that is connected on the frame; drag hook contacts with the moulding plastics bottle, and drag hook has lowering or hoisting gear.

The utility model stretch blow machine plastic bottle pull device, drag hook is installed on frame, drag hook contacts with the oral area of moulding plastics bottle, and the plastic bottle that is attached in the mould is pulled out, and separates, self gravitation by plastic bottle down falls again, get bottle without hand, realize automatic bottle removing, the production efficiency height, labour intensity is low, avoids both hands to be run over and injure by mould.

Stretch blow machine plastic bottle of the present utility model pull device, the lowering or hoisting gear of its described drag hook comprises the swing arm that is installed on the flexible mould sidewall, the head of swing arm is shaped on inclined ramp, inclined ramp contacts with drag hook, swing arm has steady pin, spacer pin and back-moving spring, and back-moving spring is installed on the swing arm by securing member.Working as collapsible form during matched moulds inwardly moves with flexible mould, rely on swing arm that drag hook is lifted, swing arm is positioned at the flexible mould inboard, and collapsible form outwards moves with flexible mould when die sinking, drag hook can be run into swing arm, and swing arm rotates around steady pin, and swing arm and spacer pin disengage, make drag hook run into the plastic bottle oral area, plastic bottle is pulled out from flexible mould.The lowering or hoisting gear of its described drag hook also can be to comprise rack-mounted cylinder, and the piston rod of cylinder connects drag hook, utilizes cylinder and piston rod that drag hook is lifted during matched moulds, and drag hook is put down during die sinking, and hook goes out plastic bottle from mould.Its described swing arm is installed in a side or the both sides of flexible mould, and there is the swing arm good reliability both sides.Its described cylinder and piston rod are connected a side or the both sides of drag hook, and both sides have cylinder to draw good reliability.
