Abstract
The invention discloses a push pedal guide pillar structure easy to detach. The structure comprises a lower mold base plate, an ejector mechanism, a core plate, a moving die core used for molding, and a static die core. The ejector mechanism is disposed on the lower mold base plate, the core plate is arranged on the ejector mechanism, the core plate is provided with the moving die core, a supporting pillar is thoroughly arranged among the lower mold base plate, the ejector mechanism, the core plate and the moving die core, a push pedal guide pillar, which interference fits with the lower mold base plate, is arranged on the lower mold base plate, the push pedal guide pillar goes through the ejector mechanism and reaches the core plate, the lower end of the push pedal guide pillar is provided with a shoulder, the lower end of the lower mold base plate is provided with a groove on a position which is opposite to the shoulder, the lower end of the push pedal guide pillar is provided with a guide pillar thread hole, and the inner of the ejector mechanism is provided with a guide sleeve which cooperates with the tiny gap of the push pedal guide pillar. Through the way mentioned above, the push pedal guide pillar structure easy to detach can guarantee the quality of injection moulding, at the same time, the work strength is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to the injection mold field, particularly relate to a kind of push pedal guide pillar structure that is easy to dismantle.
Background technology
Injection mold is the important process equipment during the plastics injection is produced, it generally is made up of six big systems, ejection system is an important component part in the injection mold six big systems, is used for the plastic part after the injection moulding and running gate system are expected to deviate from from mould with fixed attention.The push pedal guide pillar is a strength member in the liftout attachment, especially when the more difficult hand-stripping mode that adopts of product molding amount, or long for to guarantee thin thimble or the sleeve easy motion in the process of ejecting when ejection stroke, in the ejecting mechanism guider must be set, i.e. push pedal guide pillar device.
The push pedal guide pillar does not have very big difference with common guide pillar guide sleeve device on guiding principle and structure, generally adopt interference fit to be pressed in the corresponding template.In plastic injection mould, the push pedal guide pillar is connected in the interference mode with the counterdie seat board, by realizing releasing guiding with less matched in clearance with the guide pin bushing that is installed in the upper and lower liftout plate, and gos deep into that certain depth guarantees positional precision in the male model plate.When mould needs dismounting, generally be to begin dismounting from bottom plate earlier, because the push pedal guide pillar is to be embedded in the bottom plate stepped hole and in the interference mode to be connected with bottom plate, and guide pillar is less with the guide pin bushing fit clearance that is installed in the upper and lower liftout plate, makes that the dismounting of mould is comparatively inconvenient.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of push pedal guide pillar structure that is easy to dismantle, and can guarantee the injecting products quality, can reduce labour intensity simultaneously, enhances productivity.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of push pedal guide pillar structure that is easy to dismantle is provided, comprise the counterdie seat board, ejecting mechanism, male model plate and be used for the mavable module core of moulding, cover half benevolence, described ejecting mechanism is installed on the counterdie seat board, the male model plate is installed on the ejecting mechanism, the male model plate is provided with mavable module core, described counterdie seat board, ejecting mechanism, be equipped with support column between male model plate and the mavable module core, the push pedal guide pillar of interference fit with it is installed on the described counterdie seat board, described push pedal guide pillar passes ejecting mechanism to the male model plate, the lower end of described push pedal guide pillar is provided with shoulder, the corresponding shoulder in the lower surface of counterdie seat board is provided with groove, and the lower end of push pedal guide pillar is provided with the guide pillar screwed hole; Be provided with the guide pin bushing with the little matched in clearance of push pedal guide pillar in the described ejecting mechanism.
Preferably, described ejecting mechanism comprises liftout plate, upper ejector plate, return bar and back-moving spring down, described return bar and upper ejector plate are fixed by the shoulder fixed form, it is equal with the upper surface of male model plate that the upper surface of male model plate and return bar is passed in the upper end of return bar, also is arranged with back-moving spring on the described return bar.
Preferably, be provided with guide pin bushing in described upper ejector plate and the following liftout plate.
The invention has the beneficial effects as follows: a kind of push pedal guide pillar structure that is easy to dismantle of the present invention, simple, the easy accessibility of structure manufacturing not only reliably but also convenient, significantly improved production efficiency, simultaneously obviously reduce labour intensity to a certain extent, have good application prospects and practical significance.
