1st, the utility model increases local extrusion device, by increasing oil cylinder on mold, increases at the thick big position of product
Latch structure is squeezed, before air conditioning for automobiles part does not solidify completely, the big position of the thickness of product is squeezed, by what is do not solidified completely
Liquid metals is pressed into the region for needing feeding, and the shrinkage cavity and porosity defect at this is eliminated, and then improve product quality to force feeding
With product compactness.Local extruding is carried out to the thick general goal of air conditioning for automobiles part, the pressure testing leak detection for effectively improving product is led to
Rate is crossed, reduces air conditioning for automobiles part slip.
2nd, the utility model need to only be changed on common horizontal die casting or die casting machine, and the oil circuit of drive cylinder only need to be from
The system oil-way of former die casting or die casting machine is drawn, simple in structure, convenient for transformation, has good applicability and popularization
Property.
3rd, guide is fixed in the straight slot of cover half, so on the one hand, avoids cover half inner wall and directly connect with liquid metals
It touches, on the other hand, is stretched out from the straight slot of cover half convenient for squeeze pin and smear lubricant, adequately to be lubricated, reduced and squeeze
The consecutive production of pressurized technique is realized in friction between pin and guide.
4th, three times of air conditioning for automobiles part program point are carried out, process is simple, high degree of automation, facilitates realization
Consecutive production effectively improves production efficiency.
