Problems solved by technology

In the prior art, when taking out the workpiece, two methods are usually used: manual picking and mechanical picking. The manual picking is not only slow, but also dangerous, which is likely to cause safety accidents; while the mechanical picking in the prior art Usually, the workpiece is directly ejected from the injection mold through the ejection mechanism, and the workpiece is easy to fall into the injection mold during the falling process, resulting in various failures and reducing the operation stability of the injection molding machine
Especially for products with one mold and multiple cavities, such as plastic bottle caps of beverage bottles, the work efficiency of manual pick-up is even lower, and if the plastic bottle caps are ejected by the ejector mechanism, the plastic bottle caps will fall due to Its own gravity is lighter, and the probability of falling into the injection mold is greater

Abstract

The invention provides an injection molding machine for producing plastic bottle caps, belonging to the technical field of moulds and solving the technical problems of poor running stability and the like of the injection molding machine in the prior art. The injection molding machine comprises a base, wherein a fixed mould plate and a movable mould plate are arranged on the base and are connected through a pull rod, and can form a plurality of mould cavities used for forming the plastic bottle caps after getting close, and after the plastic bottle caps are formed, openings of the plastic bottle caps are outwards arranged. The injection molding machine also comprises a piece taking device, wherein the piece taking device comprises a piece taking plate, a clamping structure capable of fixing or loosening the plastic bottle caps is arranged on the piece taking plate, a lifting mechanism capable of driving the piece taking member to go up and down circularly is fixedly arranged on a rack, a holding frame used for holding the plastic bottle caps is arranged on the rack, and a demoulding detection device used for detecting whether the plastic bottle caps drop from the mould cavities completely is arranged on the holding frame. The injection molding machine has the advantages of good running stability and the like.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to an injection molding machine for producing plastic bottle caps. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products with plastic molding molds. Injection molding machine usually consists of injection system, clamping system, transmission system, electrical control system, heating and cooling system, safety monitoring system and so on. The function of the injection system is to heat and plasticize a certain amount of plastic within a specified time in a cycle of the injection molding machine, and then inject it into the mold cavity under a certain pressure and speed. After the injection is completed, the molten material injected into the cavity is kept fixed. The mold clamping system is ma...
