A retaining wall structure for use in die casting molds

Abstract

This invention relates to the field of die-casting mold technology, and in particular to a retaining wall structure for use in die-casting molds. The structure, installed in the mold, includes a raised edge and a groove. The mold comprises a male mold plate, a female mold plate, a male mold core, a female mold core, and a slider. The male and female mold cores are individually provided with venting channels. The slider is mounted on the male mold plate, which has a slider guide groove. The raised edge is located on the forming surface of the male mold core, and its side is inclined. The groove is located on the forming surface of the female mold core, its position corresponding to the raised edge. The side of the groove is an inclined surface corresponding to the inclined surface of the raised edge. The raised edge can be completely embedded in the groove.

Description

[Technical Field]

[0001] This invention relates to the field of die casting mold technology, and in particular to a retaining wall structure for use in die casting molds. [Background Technology]

[0002] Die casting is a method of obtaining a casting by filling a die-casting mold cavity with liquid or semi-liquid metal at high speed under high pressure and then rapidly solidifying it under pressure. The mold used is called a die-casting mold. Under high pressure and high speed conditions, die-casting molds often experience material ejection. The ejected molten material can rush into the slider guide groove, causing the slider to malfunction and resulting in burrs on the product. Molten material rushing into the slider guide groove can also easily cause the slider to jam and damage the mold.

[0003] In view of this, it is necessary to develop a retaining wall structure for use in die-casting molds to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is: in die-casting, under high-pressure and high-speed production conditions, molten material easily rushes into the slide guide groove, causing burrs on the product, and may even lead to slide jamming and damage to the mold. This invention provides a retaining wall structure for use within a die-casting mold to solve the above problem.

[0005] The solution to the technical problem of this invention is: a retaining wall structure for use in a die-casting mold, disposed in the mold, including a raised edge and a groove:

[0006] The mold includes a male template, a female template, a male mold core, a female mold core, and a slider. The male and female templates are respectively provided with corresponding male mold cores and female mold cores, and each of the male and female mold cores is provided with an exhaust channel.

[0007] A raised edge is provided on the forming surface of the male mold core, and the side of the raised edge is an inclined surface that tapers towards the top.

[0008] The groove is provided on the forming surface of the female mold core, and its position corresponds to the protrusion. The protrusion can be completely embedded in the groove. Correspondingly, the side of the groove is an inclined surface corresponding to the inclined surface of the protrusion.

[0009] Preferably, the slider is disposed on the male template, and the male template is provided with a slider guide groove, in which the slider slides out of the product.

[0010] Preferably, the protruding edge is embedded in the groove and distributed around the slider guide groove to avoid the exhaust channel, so as to prevent soup from rushing into the slider guide groove.

[0011] Preferably, the system further includes an exhaust block, which is disposed next to the male and female mold cores. The exhaust block is provided with an exhaust wave plate, and the exhaust channel is connected to the exhaust wave plate for exhausting air.

[0012] The beneficial effects of this invention are that by adding a retaining wall structure formed by the cooperation of the protruding edge and the groove, the ejected molten material can be effectively prevented from rushing into the slider guide groove during the die casting process, causing burrs on the product and the slider to jam. In addition, the protruding edge and the groove are made of inclined surfaces, which facilitates mold closing and can also effectively prevent the molten material remaining on the molding surface from rushing into the inclined surface between the two, thus protecting the mold. The structure is simple and easy to process. [Attached Image Description]

Detailed Implementation Methods

[0016] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0017] This invention provides a retaining wall structure for use in a die-casting mold, which is disposed in the mold and includes a raised edge 10 and a groove 20:

[0018] The mold includes a male template (not shown in the figure), a female template (not shown in the figure), a male mold core 1, a female mold core 2, and a slider 3. The male and female templates (not shown in the figure) are respectively provided with corresponding male mold core 1 and female mold core 2. Each of the male and female mold cores 1 and 2 is provided with an exhaust channel 4.

[0019] The slider 3 is set on the male template (not shown in the figure), and the male template (not shown in the figure) is provided with a slider guide groove (not shown in the figure). The slider 3 slides out of the product in the slider guide groove (not shown in the figure).

[0020] A raised edge 10 is provided on the forming surface of the male mold core 1, and the side of the raised edge 10 is an inclined surface that tapers towards the top.

[0021] The groove 20 is disposed on the forming surface of the female mold core 2, and its position corresponds to the protruding edge 10. The protruding edge 10 can be just embedded in the groove 20. Correspondingly, the side of the groove 20 is an inclined surface corresponding to the inclined surface of the protruding edge 10. The protruding edge 10 and the groove 20 adopt an inclined surface fit, which makes it easy for the protruding edge 10 to be quickly and easily embedded in the groove 20, reducing wear between the two. Moreover, the above-mentioned inclined surface fit can prevent soup from rushing into the inclined surface on the forming surface. After the protruding edge 10 is embedded in the groove 20, it is distributed around the slide guide groove (not shown in the figure) to avoid the exhaust channel 4, which is used to prevent soup from rushing into the slide guide groove (not shown in the figure).

[0022] The system also includes an exhaust block 5, which is located next to the male and female mold cores 1 and 2. The exhaust block 5 is provided with an exhaust wave 50, and the exhaust channel 4 is connected to the exhaust wave 50 for exhausting air.

[0023] The working principle of this invention is that when the mold is closed, since the protruding edge 10 and the groove 20 are fitted with inclined surfaces, the protruding edge 10 can be quickly and accurately embedded into the groove 20. The two work together to form a retaining wall structure, which prevents the molten material ejected under high pressure and high speed during the die casting process from rushing into the slider guide groove (not shown in the figure) and causing the slider 3 to jam. This effectively avoids the occurrence of burrs on the product, and the structure is simple and easy to process.

[0024] In summary, the beneficial effects of the present invention are that by adding a retaining wall structure formed by the cooperation of the protruding edge 10 and the groove 20, the ejected molten material can be effectively prevented from rushing into the slider guide groove (not shown in the figure) during the die casting process, which would cause burrs on the product and jamming of the slider 3. Furthermore, the protruding edge 10 and the groove 20 adopt a beveled fit, which facilitates mold closing and can also effectively prevent the molten material remaining on the molding surface from rushing into the bevel between the two, thus protecting the mold. The structure is simple and easy to process.

[0025] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
