Description

Ejector sleeve ejecting device

Technical Field

The utility model belongs to the mould field, concretely relates to department's section of thick bamboo ejecting device.

Background

The mold is one of important manufacturing equipment in the manufacturing process of the automobile lamp. Whether the product produced by the die is qualified or not is one of factors which greatly affect the product, and the die affects more than 50% in the problems of product quality and qualification rate. Whether the mold structure design is successful or not directly influences the product quality, the labor cost and the like in the later-stage product production process. Injection molds are known to consist of seven systems: (1) support (fixing) system: the parts (such as a fixed plate, a movable/fixed template, a supporting head, a supporting plate, a connecting screw and the like) are arranged to meet the structural requirements of the die. (2) Guidance (repositioning) system: the ejector plate is provided with a guide component, and the ejector plate is provided with a guide component. (3) A molding system: parts that impart shape, configuration, and dimensions to the molding material are typically made up of a core (punch), a cavity of a die, and a threaded core, insert, and the like. (4) A pouring system: it is a channel that guides the molten plastic from the injection machine nozzle to the closed mold cavity, usually consisting of a main runner, a sub-runner, a sprue and a cold well. (5) A temperature control system: in order to meet the requirements of the injection molding process on the mold, a mold temperature adjusting system (such as cooling water, hot oil, an electric heating system and the like) is required to adjust the temperature of the mold. (6) An ejection system: the device for realizing the demoulding of the plastic part and the pouring system has a plurality of structural forms, the most common demoulding mechanism comprises an ejector rod, an ejector pipe, an ejector plate, a pneumatic ejection mechanism and the like, and generally comprises an ejector rod, a reset rod, a slingshot, an ejector rod fixing plate, an ejector plate (ejector ring), an ejector plate guide column, a guide sleeve and the like. (7) An exhaust system: in order to smoothly exhaust the gas in the mold cavity, an exhaust channel is often formed at the parting surface of the mold

There are generally the following ejection systems in common use: ejector blocks (which can be divided into straight ejector blocks and inclined ejector blocks) and ejector rods (which can be divided into dome rods, flat ejector rods and square ejector rods), the existing ejection structure generally has the following disadvantages: 1. processing: the existing commonly used ejection, such as dome rod ejection, flat ejector rod ejection, square ejector rod ejection and ejector sleeve ejection, is made into an integral structure. The defect that the ejector rod is difficult to machine once the length of the ejector rod is more than 500mm, the rigidity of the ejector rod is directly influenced due to the slender ejector rod in the machining process, and the ejector rod is easy to deform in the machining process. 2.
