Abstract
The utility model discloses a heel-and-toe end injection molding die comprising an upper die, a lower die, a sprue, a cavity and a pore-forming pin; the cavity is formed after the upper die and the lower die are closed; the pore-forming pin comprises a large pore-forming pin and a small pore-forming pin; the large hole-forming pin is vertical to the obverse side of the die and passes through the cavity to form a large open pore; and the small pore-forming pin is vertical to the side of the die and passes through the cavity to form a small open pore. The heel-and-toe end injection molding die provided by the utility model is simple in structure and convenient to machine; the heel-and-toe end injection molding die can be used for large-scale production for enterprises so that the cost is reduced, and the efficiency is increased; and a finished product is attractive in appearance and smooth in surface so that the requirements of people are met.
Description
Technical field
The utility model relates to a kind of mould, says more specifically a kind of heel toe-end head injection forming mold.
Background technology
Heel toe-end head is a kind of strength member on frame, and the accuracy that heel toe-end head is done manual work has influence on directly that the heel toe of frame cover plate gagger is poor, and traditional heel toe-end method for making head form is single, complex structure, and the accuracy of finished product is not high, causes affecting the benefit of enterprise.
Summary of the invention
The purpose of this utility model has been to provide a kind of heel toe-end head injection forming mold, is the mould that forms according to the actual conditions manufacturing to the part demand, and is not only simple in structure, can realize batch production, and the accuracy of finished product is also very high.
The technical solution of the utility model is as follows: a kind of heel toe-end head injection forming mold, comprise upper die and lower die, cast gate, die cavity, pore-forming pin, form die cavity after described upper die and lower die matched moulds, described pore-forming pin is divided into large pore-forming pin and little pore-forming pin, die cavity is run through in described large pore-forming pin vertical mold front, form large opening, die cavity is run through in described little pore-forming pin vertical mold side, is split into little perforate.
A kind of injection mold of the present utility model injects mold cavity by cast gate with liquid, forms according to demand irregularly shapedly, and the pore-forming pin forms perforate on part.
As preferably, described large opening quantity is two, and diameter is 10mm, and described little the number of openings is one, and diameter is 5mm.
As preferably, described die cavity and cast gate join, and are provided with between described die cavity and cast gate to annotate to water passage.
As preferably, be provided with the die lifter that coordinates the die cavity molding in described counterdie.
As preferably, described upper die and lower die are provided with fixing hole, by fixing hole, upper die and lower die are fixed after described upper die and lower die matched moulds.
The utlity model has following beneficial effect: the utility model is simple in structure, and is easy to process, greatly shortened injection cycle, saved cost, improved efficient, and enterprise can produce in batches, and finished product is smooth, attractive in appearance, satisfies people's demand.
