Abstract

The invention provides a mold of a front mold ejection and demolding structure. The mold comprises an upper clamping plate, a mold cavity fixing plate, a mold core fixing plate, a molding core base plate, a core pin, a square iron, an ejector plate cover plate, an ejector plate push plate, a lower clamping plate, a molding cavity guide column, an upper core pin, a molding cavity pull rod, a pull rod spring, a mold cavity and a mold core, wherein the mold core can slide in an upper mold core slot in the molding cavity fixing plate after a mold is opened; the pull rod spring is that the molding core slides in the upper mold core slot of the molding cavity fixing plate to eject a power source; the molding cavity guide column is a guide part. According to the mold of the front mold ejection and demolding structure, a product has requirements on the inner appearance quality and the outer appearance quality, and the number of through holes is larger, so that the surface quality of hole positions of the product can be effectively guaranteed; the mold production and manufacturing cost and the product injection molding cost are reduced; the mold is reasonable in structural design, compact in structure, stable in work, safe, reliable and convenient to use.

Description

A kind of front mould ejection device structure mold
Technical field
The present invention relates to injection mold mechanism design field, be specially a kind of front mould ejection device structure mold.
Background technology
When plastic products are molded; the appearance of product require can not flaw time; if apparent hole is through hole; then during Making mold; must will touch the face of wearing to stay and core side; if interior sight face also have higher quality requirement and number of openings is more time; then through hole touch wear can only change between profiled member mutual inserted through; inside and outside surface quality requirements of product is protected with this; thus; designing inserted through needs certain moduli lamps structure between profiled member, ensures the surface quality of product when ensureing that product is deviate from from the demoulding in die cavity with this.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of front mould ejection device structure mold, reasonable in design, compact conformation, and working stability is safe and reliable, easy-to-use;
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of front mould ejection device structure mold, comprises upper clamping plate, impression bolster, core fixing plate, core plate, type pin, square iron, ejector retainner plate cover plate, ejector retainner plate push pedal, counterdie seat board, die cavity guide pillar, mo(u)ld top half pin, die cavity pull bar, pull-rod spring, die cavity, core.
As preferably, described mould mould bases is made up of upper clamping plate, impression bolster, core fixing plate, core plate, square iron, ejector retainner plate cover plate, ejector retainner plate push pedal, counterdie seat board; Described mould molding parts are made up of type pin, mo(u)ld top half pin, die cavity, core; Type pin is installed in ejector retainner plate cover plate; Mo(u)ld top half pin is installed on impression bolster;
As preferably, described core can slide after mould die sinking in impression bolster upper cores groove;
As preferably, described pull-rod spring is that core slides and ejects motive force source in impression bolster upper cores groove, and die cavity guide pillar is its guide elements;
As preferably, described type needle set has shaping and ejecting function.
Beneficial effect: a kind of front mould ejection device structure mold that the present invention adopts technique scheme to provide, when product has inside and outside sight face quality requirement and number of openings is more, effectively can ensure the surface quality of holes of products position, reduce mould and manufacture cost and product injection moulding cost; Mould structure design is reasonable, compact conformation, and working stability is safe and reliable, easy-to-use.
Accompanying drawing explanation
Fig. 1 is a kind of front mould ejection device of the present invention structure mold structure composition schematic diagram.
Detailed description of the invention
Figure 1 shows that related description figure of the present invention;
A kind of front mould ejection device structure mold, comprises upper clamping plate 1, impression bolster 2, core fixing plate 3, core plate 4, type pin 5, square iron 6, ejector retainner plate cover plate 7, ejector retainner plate push pedal 8, counterdie seat board 9, die cavity guide pillar 10, mo(u)ld top half pin 11, die cavity pull bar 12, pull-rod spring 13, die cavity 14, core 15.
Described mould mould bases is made up of upper clamping plate 1, impression bolster 2, core fixing plate 3, core plate 4, square iron 6, ejector retainner plate cover plate 7, ejector retainner plate push pedal 8, counterdie seat board 9; Described mould molding parts are made up of type pin 5, mo(u)ld top half pin 11, die cavity 14, core 15; Type pin 5 is installed in ejector retainner plate cover plate 7; Mo(u)ld top half pin 11 is installed on impression bolster 2; Described core 15 can slide after mould die sinking in impression bolster 2 upper cores groove; Described pull-rod spring 13 ejects motive force source for core 15 slides in impression bolster 2 upper cores groove, and die cavity guide pillar 10 is its guide elements; Described type pin 5 has shaping and ejecting function.
During real work, as shown in Figure 1, its motion running can be divided into several step:
1) after die cavity ejection die die cavity is opened, die cavity 14 ejecting with under the guiding of die cavity guide pillar 10 at pull-rod spring 13, is close to core 15 and moves together, and now, mo(u)ld top half pin 11 is not due to fixing active, thus product is released from mo(u)ld top half pin 11 by die cavity 14; Until product after die cavity 14 is released, die cavity pull bar 12 will hold die cavity 14, limit it and continue to move ahead, and product and die cavity 14 depart from, thus, complete the demoulding of product in die cavity;
2) core ejects injection machine push rod and will carry out repulsive-type maglev pin 5 by promoting ejector retainner plate push pedal 8, is released by product, complete the complete demoulding of product from core 15;
3) when resetting, before mold cavity is closed, ejector retainner plate cover plate 7, ejector retainner plate push pedal 8, type pin 5 push up back by mould release link, then core 15 and die cavity 14 are fitted, promote the elastic force that die cavity 14 overcomes pull-rod spring 13, led by die cavity guide pillar 10 and return, mould closes, and waits for that next injection cycle starts.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
