Abstract
The utility model provides an injection mold for a connecting rod of an automotive driving motor. The injection mold comprises a movable mold fixing plate, a push plate, a push rod fixing plate, a push rod, a movable mold cavity plate, a cavity and a plurality of mold cores, wherein the push plate is arranged on the movable mold fixing plate; the push rod fixing plate is arranged on the push plate; the push rod is arranged on the push rod fixing plate; the movable mold cavity plate is arranged on the push rod; the cavity is formed in the movable mold cavity plate; the mold cores are arranged in the cavity; a plurality of one-way exhaust valves are arranged on the movable mold cavity plate and lead to the cavity. The injection mold for the connecting rod of the automotive driving motor has the advantages of thoroughness in exhausting, fullness in filling, applicability to injection molding in a high-pressure environment, high working efficiency, uniformity in injection molding and the like.
Description
Technical field
The utility model relates to auto-parts and manufactures field, is specifically related to automobile drive electric motor connecting rod injection mold.
Background technology
A kind of processing method of using when injection mo(u)lding is some complex-shaped parts of batch production, specifically refer to the material melted that is heated injected to die cavity by high pressure, after cooling curing, obtains formed products.Injection mold is a kind of instrument of producing plasthetics, it is also the instrument of giving plasthetics complete structure and accurate dimension, injection mold is divided into the thermosetting plastic mould according to shaping characteristic, two kinds, thermoplastic plastic's mould, divide into the biography mold according to moulding process, blow molding die, draw mould, thermoforming mould, hot-die, injection mould etc., wherein hot-die can be divided into excessive formula again in the flash mode, half excessive formula, three kinds of the formulas of not overflowing, injection mold is comprised of dynamic model and cover half two parts, dynamic model is arranged on the moving die plate of injection moulding machine, cover half is arranged on the fixed form of injection moulding machine, dynamic model and cover half closed formation running gate system and die cavity when injection moulding, during die sinking, dynamic model separates in order to take out plastic products with cover half.Existing injection mold is when filling melt plastic cement, the gas existed in mould is difficult for draining, bubble enters in plastic cement, makes the shot deficiency, makes the cooling rear finished form of plastic cement irregular, make end properties unstable simultaneously, especially in the manufacturing process of some specialities, in order to make product, keep certain specific character, need in the environment of high pressure, carry out injection moulding, more be unfavorable for the discharge of gas in mould, greatly affected the quality of finished product.
Summary of the invention
Technical problem to be solved in the utility model is to provide automobile drive electric motor connecting rod injection mold, reasonable in design, simple in structure, manufacture easyly, can when injecting plastic cement, drain the gas existed in mould, avoid gas to incorporate plastic cement, avoid occurring the problems such as finished form is irregular, unstable properties, especially can be applicable to the technique of high-pressure injection moulding, make plastic cement can fill up die cavity, guarantee the quality of finished product, high efficiency, can make injection moulding more even simultaneously.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: automobile drive electric motor connecting rod injection mold, comprise dynamic mould fixing plate, be located at push pedal on dynamic mould fixing plate, be located at ejector pin retaining plate in push pedal, be located at push rod on ejector pin retaining plate, be located at dynamic model cavity plate on push rod, be located at die cavity on the dynamic model cavity plate, be located at the some core rods in die cavity, described dynamic model cavity plate is provided with some one-way exhaust valves, leads to die cavity.
As preferably, described one-way exhaust valve adopts four, minute is located at four sides of movable model chamber plate, thereby makes the discharge of gas in mould more thorough, has guaranteed that plastic cement can fill up die cavity, has guaranteed the quality of finished product.
As preferably, described core rod adopts four, evenly is located in die cavity, thereby can realizes the injection moulding manufacture of a plurality of finished products simultaneously, has greatly accelerated operating efficiency, has improved output.
As preferably, described four core rods are communicated with by communication channel, thereby make injection moulding more even, quicker.
Beneficial effect:
The automobile drive electric motor connecting rod injection mold that the utility model adopts technique scheme to provide, reasonable in design, simple in structure, manufacture easyly, can when injecting plastic cement, drain the gas existed in mould, avoid gas to incorporate plastic cement, avoid occurring the problems such as finished form is irregular, unstable properties, especially can be applicable to the technique of high-pressure injection moulding, make plastic cement can fill up die cavity, guarantee the quality of finished product, high efficiency, can make injection moulding more even simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, dynamic mould fixing plate 1, push pedal 2, ejector pin retaining plate 3, push rod 4, dynamic model cavity plate 5, die cavity 6, core rod 7, one-way exhaust valve 8, communication channel 9.
The specific embodiment
As shown in Figure 1, automobile drive electric motor connecting rod injection mold, comprise dynamic mould fixing plate 1, be located at the push pedal 2 on dynamic mould fixing plate 1, be located at the ejector pin retaining plate 3 in push pedal 2, be located at the push rod 4 on ejector pin retaining plate 3, be located at the dynamic model cavity plate 5 on push rod 4, be located at the die cavity 6 on dynamic model cavity plate 5, be located at the some core rods 7 in die cavity 6, described dynamic model cavity plate 5 is provided with some one-way exhaust valves 8, lead to die cavity 6, described one-way exhaust valve 8 adopts four, divide four sides that are located at movable model chamber plate 5, described core rod 7 adopts four, evenly be located in die cavity 6, described four core rods 7 are communicated with by communication channel 9.
During real work, when injecting plastic cement, gas in mould thoroughly can be discharged from four one-way exhaust valves 8, avoid the gas retained to incorporate plastic cement, avoided occurring the problems such as finished form is irregular, unstable properties, especially can be applicable to the technique of high-pressure injection moulding, can make plastic cement fill up die cavity 6, guarantee the quality of finished product, high efficiency, can make injection moulding more even simultaneously.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used the terms such as dynamic mould fixing plate 1, push pedal 2, ejector pin retaining plate 3, push rod 4, dynamic model cavity plate 5, die cavity 6, core rod 7, one-way exhaust valve 8, communication channel 9, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
