Description

Die-casting die for die-casting product with anisotropic hole

Technical Field

The invention relates to a die-casting die for an aluminum alloy product, in particular to a die-casting die for die-casting a product with anisotropic holes.

Background

With the development of the automobile industry, the requirements on energy conservation and air tightness are gradually improved, the reduction of cost is a constant theme in the industry, and the integration of a plurality of parts and assembly is a development trend of the whole industry, and is particularly reflected in the complexity of each product. In the case of die-cast products, a plurality of channels are often formed in the same product, so that a plurality of holes with different directions, i.e. holes with different directions, are present on the surface of the product. In order to form a plurality of holes in different directions on a product, corresponding loose cores need to be arranged on the existing mold, and corresponding hydraulic cylinders are arranged to control the loose cores to move. As the number of the holes is increased and the directions are different, the number of hydraulic cylinders required to be arranged is increased, so that the existing die-casting die is difficult to improve the structure and is used for die-casting and molding products. Therefore, only new die-casting molds can be developed again, so that the original die-casting equipment is replaced, and the die-casting cost of enterprises is increased.

The invention aims to provide a die-casting die for die-casting a product with a hole with different directions, which solves the problem that the die-casting production of the product with the hole with different directions is difficult to realize by improving the die-casting die with a single hole.

In order to achieve the above object, a basic scheme of the present invention provides a die-casting die for die-casting a product with an anisotropic hole, including a die core and a slide seat, wherein the die core is slidably provided with a first loose core and a second loose core for forming the anisotropic hole of the product, the first loose core and the second loose core are arranged on different surfaces, the first loose core and the second loose core are slidably connected to the same slide seat, the slide seat is provided with a first sliding groove for driving the first loose core to move, and the slide seat is provided with a second sliding groove for driving the second loose core to move.

The beneficial effect of this basic scheme lies in: adopt such setting, a plurality of slide of sharing of loosing core that use in the incorgruous hole that forms the product to the realization is controlled loosing core of a plurality of not equidirectional in the slip direction of original slide, need not to control a plurality of removals of loosing core through setting up a plurality of pneumatic cylinders, and then realizes carrying out die-casting shaping to the product that has the incorgruous hole after adjusting loosing core on current die casting die's basis, thereby reduces the die-casting cost of enterprise.

Further, a first guide slider is arranged between the first core pulling device and the sliding seat, the first guide slider is statically connected with the sliding seat, the first sliding groove is formed in the first guide slider, and the first core pulling device is provided with a first connecting portion which is located in the first sliding groove and slides along the first sliding groove. By adopting the arrangement, the transmission action between the first loose core and the sliding seat is more reliable in a high-temperature environment, so that the reliability of the die-casting die is improved.

Furthermore, the first guide sliding block is detachably connected with the sliding seat. By adopting the arrangement, the first guide sliding block can be detached and replaced, so that the maintenance cost is reduced. Meanwhile, the first guide sliding block is replaced, so that the core pulling device can adapt to different core pulling, and different products can be produced.

Further, a second guide sliding block is arranged between the second loose core and the sliding seat, the second guide sliding block is statically connected with the sliding seat, a second sliding groove is formed in the second guide sliding block, and a second connecting portion which is located in the second sliding groove and slides along the second sliding groove is arranged on the second loose core. By adopting the arrangement, the reliability of the die-casting die is further improved.

Furthermore, the second guide sliding block is detachably connected with the sliding seat. By adopting the arrangement, the applicability of the die-casting die is further improved.

Furthermore, the first loose core and the second loose core are both inserted into the mold core and are in sliding connection with the mold core.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the core drawing device comprises a sliding seat 1, a first guide slide block 2, a first slide groove 21, a first core drawing 3, a mold core 4, a mold cavity 41, a second guide slide block 5, a second slide groove 51, a second core drawing 6 and a fixed guide rail 7.

The embodiment is substantially as shown in figures 1 to 7 of the accompanying drawings: a die-casting die for die-casting a product with a counter-directional hole comprises a die core 4 and a sliding seat 1, wherein the sliding seat 1 is positioned on one side of the die core 4 in the horizontal direction in the embodiment. The die casting mould also comprises a fixed guide 7 which supports the slide 1, so that the direction of movement of the slide 1 is now present via the fixed guide 7.

One side of the mold core 4 close to the sliding seat 1 is provided with a first loose core 3 and a second loose core 6 which are used for forming a different-direction hole of a product in a sliding mode, and the first loose core 3 and the second loose core 6 are arranged in a different-surface mode. In this embodiment, the first core 3 and the second core 6 are inserted into the mold core 4 and slidably connected to the mold core 4, and specifically, the mold core 4 is provided with a second through hole for the first core 3 to be inserted into the first through hole and for the second core 6 to be inserted into, so that the moving directions of the first core 3 and the second core 6 are limited by the arrangement of the first through hole and the second through hole, and the mold core 4 performs positioning support on the first core 3 and the second core 6.

The first core pulling 3 and the second core pulling 6 are slidably connected to the sliding base 1 towards one end of the sliding base 1, in this embodiment, the sliding base 1 is connected to a first guide sliding block 2, the first guide sliding block 2 is provided with a first sliding groove 21, preferably, the first sliding groove 21 is a sliding groove with a T-shaped cross section, the first core pulling 3 is provided with a first connecting portion which is located in the first sliding groove 21 and slides along the first sliding groove 21, and the first connecting portion is of a T-shaped cross section. Preferably, the first guide slider 2 is detachably connected to the sliding base 1, for example, the first guide slider 2 is connected to the sliding base 1 by a bolt. The slide seat 1 is connected with a second guide slide block 5, the second guide slide block 5 is provided with a first slide groove 21, preferably, the second slide groove 51 is a slide groove with a T-shaped cross section, the second loose core 6 is provided with a second connecting part which is positioned in the second slide groove 51 and slides along the second slide groove 51, and the second connecting part is T-shaped. Preferably, the second guide shoe 5 is detachably connected to the slide 1, for example, the second guide shoe 5 is connected to the slide 1 by a bolt.
