Description
Technical field
The utility model is related to technical field of mold, more particularly to a kind of preceding moulding/demoulding structure.
Background technology
In injecting products production, ejection device is carried out using ejecting mechanism more than the knockout course after product shaping, easily existed
The phenomenon in die cavity before glue part is integrally bonded at occurs during die sinking, that is, occurs viscous preceding mould, sticking to mould needs to carry out secondary weight to product,
Core rod crushing can be caused bad, production efficiency is had a strong impact on, production cost is added.
Utility model content
Goal of the invention of the present utility model is to provide a kind of preceding moulding/demoulding structure, the technology provided using the utility model
Scheme can avoid the generation of viscous preceding mould phenomenon during injecting products die sinking, without carrying out secondary weight to product,
Avoid core rod crushing.
In order to reach foregoing invention purpose, the utility model provides a kind of preceding moulding/demoulding structure, including front template and rear mold
Plate, is embedded with the core rod for accommodating injecting products between the front template and rear pattern plate；Use is offered in the front template
In the holding tank of the embedded core rod, the holding tank it is opening down, formed for the demoulding for the de-molding injection molded products
Face；The blind hole vertical with the stripping surface is offered in the bottom of the holding tank, spring and push rod are provided with the blind hole；
The bottom of the blind hole is fixed in one end of the spring, and the other end props up the push rod；It is provided with the opening of the blind hole
Provided with the boss matched with the ring-type chuck on ring-type chuck, the end face contacted on the push rod with the spring, institute is made
The outside of the blind hole can be extend out to by stating the end of push rod.
It is preferred that, the blind hole is located at the centre position of the holding tank.
Therefore, using the technical scheme of the utility model embodiment, have the advantages that：The utility model is preceding
The receiving trench bottom for being used to be embedded in the core rod on mould is provided with blind hole, and is provided with spring and push rod in blind hole, is molding
Cheng Zhong, front template departs from after rear pattern plate, and injecting products are moved with front template, and push rod is downward under the elastic force effect of spring after die sinking
Ejection, aided injection mould product smoothly departs from front template, and ejection device action is then completed again and allows product smoothly to depart from rear mold, is reached
Production safety is stable to be prevented effectively from the secondary weight of product, the purpose of core rod crushing.This structure utility model mould structure is reasonable, plus
Work is simple, production safety and stably.
Brief description of the drawings
, below will be to this practicality in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The accompanying drawing used required in new embodiment or description of the prior art is briefly described.Drawings in the following description are only

Fig. 3 is enlarged drawing at A in embodiment Fig. 2.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
It is explicitly described.
Ejection device is carried out using ejecting mechanism more than knockout course after injecting products shaping, easily occurs glue in die sinking
Phenomenon before part is integrally bonded in die cavity, sticking to mould is needed to carry out secondary weight to product, and core rod crushing can be caused bad.
Fig. 1-2 is referred to, in order to solve the above-mentioned technical problem, present embodiment discloses a kind of preceding moulding/demoulding structure, before this
Moulding/demoulding structure includes front template 10 and rear pattern plate 20, is embedded between front template 10 and rear pattern plate 20 for accommodating injecting products
60 core rod 30.
It should be clear that structure, ratio, size depicted in this specification institute accompanying drawing etc., only to coordinate disclosed in specification
Content, for those skilled in the art understand with read, be not limited to the enforceable qualifications of the utility model,
Therefore not having technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influenceing this reality
