Description

One-die four-cavity casting die for low-pressure casting of motor shell of new energy automobile

Technical Field

The utility model relates to a four chamber casting moulds of new energy automobile motor casing low pressure casting one mould.

Background

At present, because the traditional gravity casting or low-pressure casting needs thick and large sprue gates and riser head feeding, the sprue gates and the riser heads are very thick and solid, so that long pressure maintaining and cooling time is needed to enable products to be sequentially solidified until the products are completely solidified, the production efficiency is low, and the daily productivity of a set of 1-out-1 moulds of a casting device for producing motor casings is only 150 plus 200 pieces.

Disclosure of Invention

The utility model aims at overcoming the above not enough, provide a new energy automobile motor casing low pressure casting one mould four-chamber casting mould of cost reduction, promotion productivity.

The purpose of the utility model is realized through the following technical scheme: the utility model provides a four chamber casting moulds of new energy automobile motor casing low pressure casting one mould, includes lower bolster and cope match-plate pattern, and the cope match-plate pattern is equipped with four outer die cavitys, and every outer die cavity intracavity is equipped with the mould and looses core, and every outer die cavity and the last mould that corresponds are loosed core and are formed the mould chamber between, and every goes up the mould and take out the in-core and all are equipped with the cooling water route, and every mould chamber bottom is equipped with a plurality of die blocks and waters, and the die block is watered and is communicated with each other with the runner, and on the lower bolster was arranged in to the runner, was equipped with four runners on the lower bolster promptly.

The utility model discloses a further improvement lies in: an ejector plate is arranged below the upper template.

The utility model discloses a further improvement lies in: each outer die cavity is composed of a plurality of side sliding blocks, and the side sliding blocks are connected with side sliding block oil cylinders.

Compared with the prior art, the utility model has the following advantage:

1. the investment cost of casting equipment is reduced: the utility model can achieve the output of 4 devices by only needing 1 casting device;

2. the cost of the die is reduced: the cost of 4 sets of 1-out dies is higher than that of 1 set of 1-out-4 dies;

3. the cost of casting personnel can be reduced: the utility model only needs to be equipped with 1 casting machine production personnel;

4. the productivity is greatly improved: the daily production capacity of a casting device provided with a set of 1-out-4 moulds for producing the motor shell can reach 600-plus-800 pieces, which is 4 times that of the 1-out-1 mould.

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of a lower template;

reference numbers in the figures: 1-lower template, 2-upper template, 3-upper mold core pulling, 4-mold cavity, 5-cooling water path, 6-bottom mold pouring channel, 7-pouring gate, 8-ejector plate, 9-side slide block and 10-side slide block oil cylinder.

The specific implementation mode is as follows:

in order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Elements and features described in one embodiment of the invention may be combined with elements and features shown in one or more other embodiments.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 2 the utility model relates to an embodiment of a four chamber casting moulds of new energy automobile motor casing low pressure casting mould, including lower bolster 1 and cope match-plate pattern 2, cope match-plate pattern 2 is equipped with four outer die cavitys, and every outer die cavity is equipped with the mould and looses core 3, and every outer die cavity looses core 3 between and forms mould chamber 4 with the last mould that corresponds, all is equipped with cooling water route 5 in every

last mould core

3, and 4 bottoms in every mould chamber are equipped with a plurality of die blocks and water 6, and die block is watered 6 and is communicated with each other with runner 7, and on runner 7 was arranged in lower bolster 1, be equipped with four runners 7 on the lower bolster 1 promptly, aluminium liquid passed through runner 7, die block is watered 6 and is got into mould chamber 4.

An ejector plate 8 is arranged below the upper template 2, the ejector plate 8 is used for installing an ejector pin, and the ejector pin can eject a product.

Each outer die cavity is composed of a plurality of side sliding blocks 9, the side sliding blocks 9 are connected with side sliding block oil cylinders 10, namely the side sliding blocks 9 are spliced to form the outer die cavity, the side sliding block oil cylinders 10 drive the side sliding blocks 9 to move after casting is completed, the outer die cavities are separated, and product demoulding is facilitated.

In order to ensure that the product quality in each cavity is consistent, a cooling water channel 4 is arranged in each die cavity 3, so that each die cavity 3 is ensured to be uniformly and stably filled with aluminum liquid, and the cooling parameters of each die cavity 3 can be independently controlled and are not influenced by each other. The utility model discloses effectively improve the production output, practiced thrift the cost of making and producing greatly.

Finally, it should be noted that: although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
