Abstract
The invention relates to the technical field of molds, in particular to an injection mold. The injection mold is characterized by comprising a left mold block and a right mold block, one side of the left mold block is a provided with product forming cavity and the other side is provided with a cavity, an ejector top plate is disposed in the cavity, a sprue puller is fixedly installed in the center of the ejector top plate, two identical ejector pins are fixedly connected with the portion and the lower portion of the ejector top plate, the ejector pins are slightly longer than the sprue puller, an ejector is movably connected at the opening of the cavity, the length of the ejector that extends into the cavity can be set according to requirement, the right mold block includes a cavity which matches with the product forming cavity of the left mold, and a sprue bushing is arranged in the middle of the right mold block. According to the injection mold, tightness of mold forming is strengthened by means of the sprue puller, at the meantime the finished product and the mold are protected during demolding through the ejector pins so that the mold is not easy to damage during mold forming, and the mold is more durable in use by adding an ejector retainer plate behind the ejector top plate.
Description
Technical field
The present invention relates to technical field of mold, specifically a kind of injection mold.
Background technology
Traditional injection mold, it is generally divided into mold and lower grinding tool, this mould is suitable for producing simple in construction or the middle product without plug, but when having the product of plug in the middle of product, if adopting traditional injection mold, such operation can cause that core side is caused skew by huge pressure, and when the demoulding, it is necessary to prizing the product ability demoulding, at this moment product is under hot environment, mechanical strength is relatively low, it is easy to deforms or destroys.
Summary of the invention
The purpose of the present invention is for overcoming the deficiencies in the prior art, it is provided that one conveniently becomes moulding/demoulding long-lived injection mold simultaneously.
In order to achieve the above object, the present invention devises a kind of injection mold, it is characterized in that: it includes left mould block and right module, described left mould block side is the die cavity for finished product sizing, opposite side has a cavity, thimble panel it is provided with in cavity, thimble middle panel is installed with sprue puller, thimble panel is also respectively fixedly connected with two identical thimbles up and down, described thimble ratio draws material dry slightly longer, be connected with top rod at described cavities open place, top rod can be arranged as required to enter the length in cavity.Described right module includes the die cavity matched with left mould block-type chamber, arranges organic nozzle in centre position.
Further, described sprue puller end draws material mouth with the embedding mouth of triangle, for fixing material and the pulling force of sprue puller being transmitted to material.
Further, it is additionally provided with, between described thimble panel and top rod, the Ejector Retainer Plate that a block size is identical with thimble panel, is used for making thimble panel uniform stressed, it is prevented that push up the intermolecular forces of rod and thimble panel and deform upon.
The present invention is compared with the existing technology; the present invention enhances tightness when mould becomes mould by arranging sprue puller; finished product die when thimble protects the demoulding is set simultaneously, makes mould be not easy when becoming mould impaired, after thimble panel, pretend Ejector Retainer Plate make mould more durable in use.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention.
Referring to Fig. 1,1 is Ejector Retainer Plate；2 is left mould block；3 is top rod；4 is thimble panel；5 is thimble；6 is die cavity；7 is right module；8 is machine nozzle；9 is sprue puller；10 for drawing material mouth.
Detailed description of the invention
As shown in Figure 1, the present invention draws together left mould block and right module, described left mould block side is the die cavity for finished product sizing, opposite side has a cavity, is provided with thimble panel in cavity, and thimble middle panel is installed with sprue puller, thimble panel is also respectively fixedly connected with two identical thimbles up and down, described thimble ratio draws material dry slightly longer, is connected with top rod at described cavities open place, and top rod can be arranged as required to enter the length in cavity.Described right module includes the die cavity matched with left mould block-type chamber, arranges organic nozzle in centre position.Described sprue puller end draws material mouth with the embedding mouth of triangle, for fixing material and the pulling force of sprue puller being transmitted to material.It is additionally provided with, between described thimble panel and top rod, the Ejector Retainer Plate that a block size is identical with thimble panel, is used for making thimble panel uniform stressed, it is prevented that push up the intermolecular forces of rod and thimble panel and deform upon,
During matched moulds, material is positioned between the die cavity of left mould block and right module, and material is fixed on sprue puller drawing material mouth on, right module module to the left is made to draw close, thimble is to cavity contract, drive material module to the left close, the Ejector Retainer Plate of thimble panel extruding simultaneously, Ejector Retainer Plate extruding top rod, after complete matched moulds, thimble is just collapsible into left mould block, and sprue puller enters left inside modules, drives material to enter left mould block, the projection of pull-out certain length, simultaneously in the extrusion process of left mould block and right module, material fills up machine nozzle, material is thus formed finished product.
In the process of die sinking, first right module being removed, then advanced inwards by top rod, top rod extruding Ejector Retainer Plate, Ejector Retainer Plate extruding thimble panel, module is extruded by thimble panel by the fixing thimble connected and sprue puller, this completes knockout course.
