Ring the presentation quality of product, off-dimension even casting is scrapped.
Summary of the invention
In view of this, in view of the shortcomings of the prior art, the utility model provides a kind of positioning molding it is more acurrate, wear-resisting,
The positioning mould-matching structure of metal type cast mold with long service life.
In order to solve the above technical problems, technical solution adopted in the utility model is: a kind of metal type cast mold
Mould-matching structure, including upper die and lower die are positioned, the upper die and lower die are corresponding to be fastened, a wherein diagonal line two for the upper mold
End is respectively provided with positioning pin, and an other diagonal line both ends for the upper mold are respectively provided with positioning convex platform, and wherein one of the lower die
Diagonal line both ends are respectively provided with the set pin sleeve to match with the positioning pin, and an other diagonal line both ends for the lower die are all provided with
Set the positioning concave stations to match with the positioning convex platform.
Preferably, the positioning pin is cylindrical type pin, and the set pin sleeve is cylindrical hole.
Preferably, the fit clearance of the positioning convex platform and the positioning concave stations is greater than the positioning pin and the positioning pin
The fit clearance of set.
Preferably, two positioning convex platforms with the upper mold be integrally formed, two positioning concave stations with the lower die
It is integrally formed.
Preferably, the upper mold and the lower die are vermicular cast iron product.
Compared with prior art, the beneficial effects of the utility model are as follows:
The positioning mould-matching structure of the utility model metal type cast mold, on the basis of traditional moulds pin is solid, it is fixed to increase
Position boss and positioning concave stations, increase orientation range, and under positioning pin and guide abrasion condition, two positioning tables still play molding positioning
Effect avoids mismatch when upper mold is molded with lower die, stings mould, molds phenomena such as not in place, reduce the risk of deformation, abrasion,
Die life is greatly enhanced, mold repair cost is reduced.
In addition, the fit clearance of positioning convex platform and positioning concave stations is greater than the fit clearance of positioning pin and set pin sleeve, it is convenient
Divide mould after casting complete；Positioning convex platform and positioning concave stations and mold are integrated, simple shape easy processing molding, material and heat
Processing mode etc. is identical as mold, and service life is substantially equivalent with die life, simultaneously as orientation range increases positioning more
Accurately；Upper die and lower die use vermicular cast iron product, and intensity is high, and elasticity modulus is big, and heat-resist, absorb shock resistance is good, absorbs impact
Load-carrying ability is strong.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model upper mold；
Fig. 2 is the structural schematic diagram of the utility model lower die:
Fig. 3 is the partial sectional view of the utility model molding rear positioning pin and set pin sleeve；
Fig. 4 is the partial sectional view of positioning convex platform and positioning concave stations after the utility model molding.
