Description

A mould examination is ejecting structure for trying before mould

Technical Field

The utility model relates to a mould processing technology field, in particular to mould examination ejecting structure for trying before mould.

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: and the ejector block (which can be divided into a straight ejector block and an inclined ejector block). A push rod (which can be divided into a dome rod, a flat push rod and a square push rod).

The defects and shortcomings of the prior art are as follows:

(1) before T0: before the trial of the mold T0, poor grinding and matching of an ejection mechanism (an ejector block, an ejector rod, a reverse guide column and the like) in the mold heating process often occurs, and the ejector block cannot be ejected normally and clamped in the mold, so that the mold cannot be trial-manufactured according to an original plan. The mould can not be trial-manufactured on time, and the whole project cycle is influenced.

(2) After batch production: the ejection system has hard points during the process of matching, and the surface of the ejection block is seriously polished. The phenomenon of galling of an ejection part of the mold in the long-time injection molding process causes the blocking of an ejection system; the mold cannot work normally.

SUMMERY OF THE UTILITY MODEL

The utility model discloses in, the major structure of mould includes supporting (fixed) system, direction (repeated positioning) system, molding system and casting system etc.. The ejector plate in the mold is used for ejecting the injection molding piece formed by injection molding out of a cavity of the injection mold.

According to fig. 1 to 3, the mold trial ejection structure used before mold trial comprises a trial ejection tool 1 fixed on a bottom plate 2 of a mold main body structure, wherein a telescopic cylinder is fixed on the trial ejection tool 1, the telescopic cylinder can be an oil cylinder 3 or an air cylinder, the telescopic cylinder is fixed on one side far away from the bottom plate 2, a through hole 11 is formed in the trial ejection tool 1, a piston rod of the telescopic cylinder penetrates through the through hole 11, and an ejection column 4 used for pushing a mold ejector plate is fixed on the piston rod of the telescopic cylinder. The ejection column 4 is in threaded connection with a piston rod of the telescopic cylinder. The trial ejection tooling 1 comprises a main body 12 for fixing the telescopic cylinder, and supporting parts 13 for fixedly connecting with the bottom plate 2 are arranged on two sides of the main body 12. The supporting part 13 is connected with the bottom plate 2 through screws, the bottom plate 2 is provided with threaded holes, the supporting part 13 is provided with round holes 14 for screws to pass through, and the supporting part 13 is also provided with waist holes 15 for screws to pass through. The longitudinal direction of the waist hole 15 is parallel to the longitudinal or width direction of the mold body 12. The round hole 14 and the kidney hole 15 are counter bored holes.

The oil cylinder 3 is connected with the trial ejection tool 1 through a screw, and a threaded hole is formed in the trial ejection tool 1. The piston rod of the oil cylinder 3 passes through the through hole 11, and a gap is reserved between the piston rod of the oil cylinder 3 and the through hole 11. After the die is finished at T0, the movable part of the die is processed and ejected by the trial ejection structure, so that the problems of poor grinding, poor processing and poor assembly in the die manufacturing process can be solved.

The working principle is as follows: each in-out action of the oil cylinder 3 drives the ejection column 4 to do an in-out circulating action. The oil cylinder 3 and the ejection column 4 are fixed on the die bottom plate 2 through the trial ejection tool 1. The mold ejector plate is pushed to repeatedly move back and forth by the one-in one-out circulation action of the ejector columns 4. One go back and forth (one in and one out) is one ejection of the mold. Thereby, the trial ejection of the die can be completed without an injection molding machine before T0. 3000 back and forth calculation is carried out for one ejection period, and if the mold is found to have the defects of jamming, dead ejection, hard spots and blackening, the mold is repaired in time. Therefore, ejection abnormity caused by mold testing of the injection molding machine on the mold is avoided, and mold testing efficiency of the mold is improved.

It should be understood that the above description of the specific embodiments is only for the purpose of explanation and not for the purpose of limitation. Obvious changes or variations caused by the spirit of the present invention are within the scope of the present invention.
