Description

Embedded exhaust block assembly

Technical Field

The invention relates to the field of die-casting die exhaust systems, in particular to an embedded exhaust block assembly.

Background

In the production of die casting moulds, in order to discharge the gas in the die cavity of the die casting mould as much as possible out of the mould during the molten metal filling process, a gas discharge block can be arranged at the position where the die cavity is connected with the mould frame so as to reduce and prevent the generation of gas hole defects in die casting parts. Usually, the vent block is arranged on the parting surface, and the gas in the cavity can be well discharged as long as the vent groove is not closed prematurely in the metal liquid filling process.

An issued chinese patent, application No. CN201721286629.2, discloses an exhaust block, comprising: first briquetting and second briquetting, along the length direction of first briquetting, the upper surface of first briquetting is provided with the strip arch, is provided with the recess that corresponds with the strip arch on the second briquetting, behind first briquetting and the lock of second briquetting, has the clearance between strip arch and the recess, and the clearance forms exhaust passage at exhaust block length direction, and the setting of this exhaust block has alleviated the technical problem that current exhaust apparatus exhaust capacity is inefficient. However, the exhaust block with the design is easy to block the exhaust holes during production and use, and the blocked exhaust block is difficult to clean during the production process of the mold.

Disclosure of Invention

The invention provides an embedded exhaust block assembly aiming at the current situation of the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows: a mosaic exhaust block assembly is presented comprising:

the exhaust fan comprises a body, wherein one end of the body along the length direction is provided with an insert mounting hole, and the side wall of the mounting hole is provided with a first exhaust groove;

the insert is detachably mounted in the insert mounting hole, the insert is provided with an exhaust hole, the exhaust hole penetrates through the insert along the thickness direction of the insert, a second exhaust groove is formed in the end part of the exhaust hole along the vertical direction, and the second exhaust groove is communicated with the first exhaust groove.

The body is provided with a material hiding groove which is used for buffering the pressure of molten metal.

At foretell an embedded exhaust block subassembly, the body is kept away from one side of the mounting hole of inserting is equipped with the exhaust breach, the exhaust breach is through the excision the body terminal surface forms.

Compared with the prior art, the exhaust block has the advantages that the region which is easy to block when the exhaust block is exhausted is split into the body and the insert, when the exhaust block is blocked, a new insert can be quickly replaced, the design reduces the cleaning difficulty of the exhaust block, and the split insert can be reused after being cleaned.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 4, a mosaic exhaust block assembly of the present invention comprises: a body 10 and an insert 20.

Be equipped with on body 10 and hide silo 11, hide silo 11 effect and have: 1. increasing the path of the high-temperature and high-pressure gas in the die cavity to be discharged out of the die cavity, thereby increasing the cooling time of the high-temperature and high-pressure gas, and 2, intercepting metal mixed in the gas discharged out of the die cavity.

An insert mounting hole 15 is formed at one end of the body 10 in the longitudinal direction, and an insert 20 is detachably mounted in the insert mounting hole 15. In order to make the insert 20 more firmly mounted, a countersunk hole may be provided on the side wall of the mounting insert 20, and a threaded hole 22 is provided on the insert 20, so that the insert 20 can be firmly locked on the body 10 by using a bolt with a size corresponding to that of the threaded hole 22, and the more the countersunk hole and the threaded hole 22 are provided, the more firmly the insert 20 is mounted, the four groups of countersunk holes and threaded holes 22 are selected.

As a preferable aspect of the present invention, the exhaust notches 12 are provided at one end of the main body 10 away from the insert mounting hole 15, the number of the exhaust notches 12 is determined according to the size of the main body 10 and the size of the product to be die-cast, and generally, the larger the die-cast product, the larger the main body 10, the more the exhaust notches 12. The exhaust gap is formed by cutting off the end face of the body 10, and the arrangement of the exhaust gap 12 further improves the exhaust performance of the real exhaust block component.

The mode of use of the invention is illustrated below by one embodiment:

the body 10 is mounted between a die cavity of a die casting mould and a mould carrier. When the die-casting die works, the molten metal liquid to be die-cast introduced into the die cavity heats the gas in the die cavity and makes the gas have a large pressure, and the heated high-temperature gas is introduced into the body 10 through the first vent hole 21, the first vent groove 14 and the second vent groove 15 and finally is discharged out of the die from the vent notch 12. The first exhaust hole 21, the first exhaust groove 14, the second exhaust groove 15 and the material storage groove 11 are used for containing metal brought out by gas, when the metal in the first exhaust hole 21, the first exhaust groove 14 and the second exhaust groove 15 reaches the exhaust performance affecting the exhaust block assembly, the insert 20 can be detached from the body 10 and cleaned of the metal attached to the upper surface, and the insert 20 cleaned can be reused.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the described embodiments may be made by those skilled in the art without departing from the scope and spirit of the invention as defined by the accompanying claims.
