Description

Autospasy model injection structure
Technical field
The present invention relates to automobile fitting manufacture field, autospasy model injection structure is specifically referred to.
Background technology
Existing injection mold typically pours the plastics after fusing in casting from mould when the plastic fittings of automobile is processed, and the demoulding will obtain required product after cooling to be formed.
But, injection mold when the deep accessory of some shaping bit comparisons is molded, occur when the accessory demoulding stick on mould and cause accessory be broken cannot the smooth demoulding situation.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided autospasy model injection structure, can smoothly realize the demoulding work of automobile fitting plastic product.
The purpose of the present invention is achieved through the following technical solutions：
Autospasy model injection structure, including upper mould and the lower mould with the mutual corresponding matching of upper mould；Upper mould includes upper die plate, the push pedal that is arranged at below upper die plate and is fixed on upper die plate lower surface and through the upper cores of push pedal, upper die plate is provided with the first spring for acting on push pedal in blind hole is provided with the end face of push pedal in blind hole；
Lower mould includes lower template and lead column, forming cavity corresponding with upper cores and pilot hole are offered in lower template, the second spring being connected with lead column is provided with pilot hole, in the presence of second spring, lead column is supported to push pedal, positioning runner is offered on pilot hole inwall, the positioning convex strip being engaged with positioning runner is provided with the outer wall of lead column；
Also include cooling water pipe, cooling water pipe includes the cooling section being arranged in upper cores, the inlet segment and water exit end that are arranged in upper die plate；One end of inlet segment is extended to outside upper die plate, and the other end of inlet segment is connected with the water inlet end of cooling section；One end of water exit end is extended to outside upper die plate, and the other end of water exit end is connected with the water side of cooling section.
Operation principle is as follows：In matched moulds, upper cores are stretched into is molded the high temperature plastics in forming cavity in forming cavity.During die sinking, the plastic product after shaping is attached in upper cores, and forming cavity is left with upper cores.Lead column causes that push pedal overcomes the effect of the first spring to withstand on the lower surface of upper die plate in the presence of second spring.Now, cooling water is flowed into by inlet segment, and the plastic product being attached in upper cores is cooled down when cooling water is by cooling section, intensity increase after plastic product cooling.As upper mould is continued up, the elastic force of second spring is gradually reduced, and lead column is gradually reduced to the power that push pedal applies, and push pedal stops that plastic product is continued up under the first spring and Action of Gravity Field, and plastic product is pushed away into upper cores, realizes the demoulding.Wherein, in the presence of by positioning runner and positioning convex strip, can prevent lead column from position skew occurring in moving process and the effect to push pedal is influenceed.The present invention carries out the demoulding after being cooled down to plastic product, overcomes the problem that forced stripper mechanism causes plastic product to deform.
The stability of operation is influenceed to avoid lead column from departing from pilot hole when upper mould and lower film are molded, further, the positioning runner includes the glissile segment of inducer and cross-sectional width more than inducer width；What the positioning convex strip included inserting inducer inserts section and width more than inducer and be engaged with glissile segment spacing section.When upper mould is molded with lower mould, spacing section is stopped by inducer, lead column can be avoided to depart from pilot hole.
Further, the cooling section is spirality.Cooling section is spirality, makes temperature conduction area bigger, improves cooling effectiveness.
Further, the also electromagnet cut off valve A including being arranged on water exit end；Electromagnet cut off valve A is closed in matched moulds, is opened in die sinking.Electromagnet cut off valve A is closed during matched moulds, the cooling water in cooling section is stopped flowing, high temperature plastics during matched moulds in forming cavity will not be cooled, it is to avoid the shaping of influence plastic product.
Further, the also electromagnet cut off valve B including being arranged on inlet segment；Electromagnet cut off valve B is closed in matched moulds, is opened in die sinking.Electromagnet cut off valve B is closed during matched moulds, the cooling water in cooling section is stopped flowing, high temperature plastics during matched moulds in forming cavity will not be cooled, it is to avoid the shaping of influence plastic product.
In sum, the advantages of the present invention are：
1st, the present invention carries out the demoulding after being cooled down to plastic product, overcomes the problem that forced stripper mechanism causes plastic product to deform.
2nd, electromagnet cut off valve A and electromagnet cut off valve B is closed during matched moulds, the cooling water in cooling section is stopped flowing, high temperature plastics during matched moulds in forming cavity will not be cooled, it is to avoid the shaping of influence plastic product.
3rd, cooling section is spirality, makes temperature conduction area bigger, improves cooling effectiveness.
