Description
Technical field
This utility model relates to automobile fitting manufacture field, specifically refers to autospasy model injection structure。
Background technology
Existing injection mold is when processing the plastic fittings of automobile, it is common that being watered by the plastics after fusing and cast from mould, after cooling to be formed, the demoulding will obtain required product。
But, injection mold, when the accessory that some molding bit comparisons of molding are deep, there will be when the accessory demoulding to stick and causes the accessory fracture cannot the situation of the demoulding smoothly on mould。
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that autospasy model injection structure, can realize the demoulding work of automobile fitting plastic product smoothly。
The purpose of this utility model is achieved through the following technical solutions:
Autospasy model injection structure, including upper mould and with the counterdie of the mutual corresponding matching of upper mould；Upper mould includes cope match-plate pattern, is arranged at the push pedal below cope match-plate pattern and is fixed on cope match-plate pattern lower surface and runs through the upper cores of push pedal, and cope match-plate pattern, in being provided with blind hole in the end face of push pedal, is provided with the first spring acting on push pedal in blind hole；
Counterdie includes lower bolster and lead, lower bolster offers the forming cavity corresponding with upper cores and pilot hole, the second spring being connected with lead it is provided with in pilot hole, under the effect of the second spring, push pedal is supported by lead, pilot hole inwall offers positioning runner, the outer wall of lead is provided with the positioning convex strip matched with positioning runner；
Also including cooling water pipe, cooling water pipe includes the cooling section being arranged in upper cores, the inlet segment being arranged in cope match-plate pattern and water exit end；One end of inlet segment extends to outside cope match-plate pattern, and the other end of inlet segment connects with the water inlet end of cooling section；One end of water exit end extends to outside cope match-plate pattern, and the other end of water exit end connects with the water side of cooling section。
Operation principle is as follows: when matched moulds, and upper cores stretches into the high temperature plastics molding made in forming cavity in forming cavity。During die sinking, the plastic product after molding is attached in upper cores, leaves forming cavity with upper cores。Lead makes push pedal overcome the effect of the first spring to withstand on the lower surface of cope match-plate pattern under the effect of the second spring。Now, cooling water is flowed into by inlet segment, and the plastic product being attached in upper cores is cooled down by cooling water through cooling section, and after plastic product cooling, intensity increases。Along with upper mould continues up, the elastic force of the second spring is gradually reduced, and the power that push pedal is applied by lead is gradually reduced, and under the first spring and action of gravity, push pedal stops that plastic product continues up, and plastic product is pushed away upper cores, it is achieved the demoulding。Wherein, by, under the effect of positioning runner and positioning convex strip, preventing lead from occurring position skew to affect the effect to push pedal in moving process。This utility model carries out the demoulding after plastic product is cooled down, and overcomes the problem that forced stripper mechanism causes plastic product to deform。
Affect the stability of operation for avoiding lead to depart from pilot hole when upper mould is with lower film die sinking, further, described positioning runner includes inducer and the cross-sectional width glissile segment more than inducer width；The section of inserting that described positioning convex strip includes inserting inducer and width are more than inducer and match with glissile segment spacing section。When upper mould and counterdie die sinking, stop spacing section by inducer, lead can be avoided to depart from pilot hole。
Further, described cooling section is spiral type。Cooling section is spiral type, makes temperature conduction area bigger, improves cooling effectiveness。
Further, the electromagnet cut off valve A being arranged on water exit end is also included；Electromagnet cut off valve A closes when matched moulds, opens when die sinking。Closing electromagnet cut off valve A during matched moulds, make the cooling water retention fluid stopping in cooling section move, during matched moulds, the high temperature plastics in forming cavity will not be cooled, it is to avoid affects the molding of plastic product。
Further, the electromagnet cut off valve B being arranged on inlet segment is also included；Electromagnet cut off valve B closes when matched moulds, opens when die sinking。Closing electromagnet cut off valve B during matched moulds, make the cooling water retention fluid stopping in cooling section move further, during matched moulds, the high temperature plastics in forming cavity will not be cooled, it is to avoid affects the molding of plastic product。
In sum, advantage of the present utility model and having the beneficial effects that:
1, this utility model carries out the demoulding after plastic product is cooled down, and overcomes the problem that forced stripper mechanism causes plastic product to deform。
2, closing electromagnet cut off valve A and electromagnet cut off valve B during matched moulds, make the cooling water retention fluid stopping in cooling section move, during matched moulds, the high temperature plastics in forming cavity will not be cooled, it is to avoid affects the molding of plastic product。
3, cooling section is spiral type, makes temperature conduction area bigger, improves cooling effectiveness。
