Abstract
The invention relates to a die-casting mould which comprises a movable mould with a movable mould cavity and a fixed mould with a fixed mould cavity. A hole-drawing core is fixed in the movable mould cavity, a positioning hole corresponding to the hole-drawing core is formed in a cavity wall of the fixed mould cavity, a radial sealing groove is formed at a position, close to the hole-drawing core, of the cavity wall of the fixed mould cavity, a first sealing ring is arranged in the radial sealing groove, a radial sealing groove is also formed at a position, close to the hole-drawing core, of a cavity wall of the movable mould cavity, a second sealing ring is arranged in the radial sealing groove, and the end portion of the hole-drawing core is in interference fit with the positioning hole. The sealing rings are added additionally, thereby being capable of preventing leakage of molten aluminum, so that product quality is improved.
Description
Technical field
The present invention relates to mould applications, relate in particular to a kind of die casting.
Background technology
At present in the brake for motorcycle industry, the buffer body of brakes utilizes the die casting moulding usually, buffer body after moulding has the via hole for assembling bolt, existing die casting comprises the dynamic model with dynamic model die cavity and has the cover half of cover half die cavity, the dynamic model die cavity is fixed with takes out the hole fuse, it is cylindrical taking out the hole fuse, takes out the via hole that the hole fuse is used to form buffer body, takes out the chamber wall of the end contact of hole fuse to the cover half die cavity after matched moulds.; the end of taking out the hole fuse is not fixed; adopt existing this die casting; in press casting procedure; because can making to take out the hole fuse, the impact that is subject to die casting aluminium water produces displacement or distortion; thereby have influence on position, the hole precision of buffer body via hole, reduce the die casting end product quality, cause follow-up processing difficulties.A kind of die casting that Chinese patent CN 202212558 U announce, solved the problems referred to above well, but Shortcomings still in above-mentioned patent takes out between hole fuse and locating hole and inevitably have leakage problem, needs to be further improved.
Summary of the invention
The objective of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of die casting.
The present invention is achieved through the following technical solutions:
A kind of die casting, comprise the dynamic model with dynamic model die cavity and the cover half with cover half die cavity, described dynamic model die cavity is fixed with takes out the hole fuse, the chamber wall of described cover half die cavity is provided with and the described corresponding locating hole of hole fuse of taking out, the chamber wall of described cover half die cavity is provided with radial seal groove near taking out fuse place, hole, radial seal groove is built-in with the first sealing ring, and the chamber wall of described dynamic model die cavity also is provided with radial seal groove near taking out fuse place, hole, and radial seal groove is built-in with the second sealing ring.
As preferably, during matched moulds, described end of taking out the hole fuse is inserted in locating hole.
As preferably, between described end of taking out the hole fuse and described locating hole, be interference fit, further improve its sealing effectiveness.
As preferably, described the first sealing ring and the second sealing ring all adopt "O"-ring.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by existing basis, having increased sealing ring, can prevent the leakage of aluminium water, thereby improves the quality of product.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
