Technical Field

The invention relates to the field of die casting, in particular to a method for removing burrs of a mold parting line of a mark insert in a corresponding die casting mold.

Background

Design and change of automobile parts are along with the development of automobile industry, in order to reduce cost and development investment, similar products (only part of structures are different) can be changed into insert structures by changing a mold, and corresponding inserts are changed during production of different products to realize product switching. Thus, only one set of mould can be opened to produce different products.

In order to distinguish different products, the part number needs to be added to the product, the part number is also used as an insert for designing during mold design, and the insert with the part number is synchronously replaced when different products are switched, so that the parts can be distinguished.

And inevitable can have the clearance between mold insert and the mould benevolence, and this clearance can unavoidably produce the burr in die-casting production process, and these burrs need be got rid of the operation through the brush in the back process. The brush can easily hurt the character when the burrs of the insert around the character are removed, and the identification degree of the product is reduced. If the characters are not damaged, special cutters are required to remove the traces along the parting line, special equipment is required, and the cost is high.

Disclosure of Invention

Aiming at overcoming the defects in the prior art, the invention mainly aims to overcome the defects in the prior art, and discloses a method for removing burrs of a mold parting line of a mark insert in a die-casting mold, which comprises the following steps:

s1, manufacturing an insert, cutting the insert into the addition of target shapes in a wire cutting mode, wherein the height of the insert is larger than the thickness of the mold core, so that the mark part of the insert is higher than the surface of the mold core;

s2, installing an insert, removing the position, where the insert needs to be installed, of the mold core by wire cutting to form an installation hole, and installing the insert into the installation hole of the mold core and fixing the insert with the mold core;

s3, producing a product, namely, producing the product after a die-casting die is closed, and after die opening, enabling the mark part on the product to be lower than the surface of the product;

and S4, wiping the surface of the product through a brush, and removing burrs on the parting line between the insert and the mold core.

Further, in step S1, the sidewall of the insert is set with an inclination angle of 0.5 °, and correspondingly, the installation position of the mold core in step S2 is also set with an inclination angle matched with the insert.

Further, in step 2, a first concave edge is circumferentially arranged at the mounting position of the insert on the lower surface of the mold core, a second concave edge is circumferentially arranged on the lower surface of the insert, and the first concave edge and the second concave edge are welded and fixed through welding rods.

Further, the mark part of the insert is higher than the surface of the die core by at least 0.5 mm.

The invention has the following beneficial effects:

the mark bulge is arranged to protrude out of the mold core, so that the mark part on the product sinks and is protected, and the mark part is prevented from being scraped when the brush deburres, and the identification degree is low. The insert and the die core are matched by adopting an inclined plane of 0.5-1 degrees, so that the insert and the die core are more tightly attached after being installed, the generation of a gap is reduced, the generation of parting line burrs is reduced, the production cost is reduced, and the processing efficiency is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A method for removing burrs on a parting line of a mark insert 1 in a die-casting die comprises the following steps as shown in figures 1-4:

s1, manufacturing an insert 1, cutting the insert 1 into a target shape in a wire cutting mode, and meanwhile, enabling the height of the insert 1 to be larger than the thickness of the mold core 2, so that the mark part of the insert 1 is higher than the surface of the mold core 2;

s2, installing the insert 1, removing the position, where the insert 1 needs to be installed, on the die core 2 by wire cutting to form an installation hole, and installing the insert 1 into the installation hole of the die core 2 and fixing the insert 1 and the die core 2;

s3, producing a product, namely, producing the product after a die-casting die is closed, and after die opening, enabling the mark part on the product to be lower than the surface of the product;

s4, wiping the surface of the product through a brush, and removing burrs on the parting line between the insert 1 and the die core 2.

Preferably, as shown in fig. 1 to 4, the sidewall of the insert 1 is provided with an inclination angle of 0.5 ° in step S1, and correspondingly, the mold core 2 is also provided with an inclination angle to fit the insert 1 at the mounting position in step S2. Through the cooperation at inclination for the clearance between mould benevolence 2 and the mold insert 1, and then reduce the production of parting line burr.

In the above embodiment, as shown in fig. 1-4, in step 2, a first concave edge 21 is circumferentially provided on the lower surface of the mold core 2 at the installation position of the insert 1, a second concave edge 11 is circumferentially provided on the lower surface of the insert 1, and the first concave edge 21 and the second concave edge 22 are welded and fixed by a welding rod.

In one embodiment, as shown in fig. 1-4, the mark portion of the insert 1 is at least 0.5mm higher than the surface of the core 2.

The structure of the insert 1 and the mold core 2 is specifically described below, and as shown in fig. 1-4, the insert 1 includes a mold core 2 and an insert 1, the insert 1 is of a square structure, and the upper surface is provided with an identification protrusion 12; the mold core 2 is internally provided with a mounting hole, the insert 1 is arranged in the mounting hole, and the mark bulge 12 protrudes out of the surface of the mold core 2. Protruding sign makes the sign part on product surface sink, and then when the parting line burr is got rid of to the brush, be less than the product surface and protected because of the sign part, can not harmed to raise the efficiency and reduce cost.

Preferably, as shown in fig. 1 to 4, four side walls of the insert 1 are provided with inclined surfaces of 0.5 to 1 degree, and inclined surfaces matched with the side walls of the insert 1 are arranged in the mounting holes. Through the cooperation of inclined plane between mold insert 1 and the mould benevolence 2 for both hug closely each other, reduce the clearance and produce, and then reduce the production of parting line burr.

In one embodiment, as shown in fig. 1-4, the insert 1 and the core 2 are fixed by welding. Preferably, the bottom of the mounting hole is provided with a first concave edge 21, the lower surface of the insert 1 is circumferentially provided with a second flange 11, and the first concave edge 21 and the second concave edge 11 are spliced to form a welding groove. The welding groove is used for storing welding spots, so that the welding spots do not protrude out of the lower surface of the mold core 2; even if the protrusion occurs, only a small amount of grinding is needed. Compared with the method that the welding groove is not arranged, the welding spot is protruded, the welding spot needs to be polished, and after the polishing step, the firmness of the welding spot is deteriorated, so that the insert 1 is not reliably connected with the mold core; if the welding spot is not polished, the die core 2 is not mounted in the die casting machine.

The above are merely preferred embodiments of the present invention, and are not intended to limit the scope of the invention; it is intended that the following claims be interpreted as including all such alterations, modifications, and equivalents as fall within the true spirit and scope of the invention.
