Abstract

The utility model discloses a cast iron mold easy to demould, which comprises a mold body provided with a cavity slot. Four side walls of the cavity slot are respectively provided with a pattern draft, and the bottom wall of the cavity slot is provided with a reinforcing rib protruding upwards. The improvement points of the cast iron mold are that the edge line of the cross section of the reinforcing rib is designed to be a circular arc line, and the distance from the vertex of the reinforcing rib to the upper surface of the bottom wall is equal to or less than the radius of the circular arc line. With the structural style of the application adopted, as the high-low undulation of the reinforcing rib is smoother, mortars such as graphite and the like can be distributed more uniformly on the surface of the reinforcing rib so as to be beneficial to demoulding; as the superficial area of the reinforcing rib, the mortars can dry quickly, thus being beneficial to demoulding as well; in addition, the structure is not easy to generate a dead angle, so that the realization of demoulding is benefited. The confirmation shows that the disengaging of an iron block from the cavity slot is better benefited if the structural style of the application is used under the condition that the same mortar is adopted for carrying out mold injection.

Description

A kind of pig mold that is easy to the demoulding

Technical field

The application relates to a kind of special-purpose spare part of pig machine, is specifically related to a kind of pig mold.

Background technology

Pig machine is the equipment that molten iron is cast continuously iron block; It has a circulation chain belt that many pig molds and carrier bar are housed that is tilted to; This chain belt is around the star gear wheel running at two ends up and down; Its workflow is: molten iron is in molten iron trough flows into pig mold, and the pig mold of filling molten iron moves up under the drive of chain belt slowly; In course of conveying, cooling device on the iron block that has crusted, cools off cool water shower to quicken the iron block cooling; Iron block comes off at head star-wheel place; Put under in the transport vehicle by chute and to transport; The iron block of indivedual difficult drop-offs comes off by taking off the cleaning of iron device, when chain belt returns, for ease of the iron block demoulding, when pig machine moves, in pig mold, sprays mortar such as graphite powder, coal slime, lime continuously.

Pig mold is directly to contact with molten iron on the pig machine and make it be shaped to the parts of iron block.As shown in Figure 1; The structure of pig mold is a die body 1 that is provided with chamber groove 2, and this chamber groove 2 is the cavity volume of splendid attire molten iron, deviates from chamber groove 2 for making the iron block that solidifies; Four sidewall 1a of

chamber groove

2,1b, 1c, 1d all also are provided with pattern draft; And, for the structural strength that improves die body 1 to avoid high temperature deformation, also be provided with the reinforcement 3 that raises up on the diapire 1e of this chamber groove 2.

It has been generally acknowledged that, the cross section of reinforcement 3 is designed to the triangle shown in Figure 2 demoulding more easily.Therefore, because the said structure of pig mold is considered to help the design of the demoulding, so this area mainly is confined to improve from the selection of plaster material the stripping result of pig mold at present.

The utility model content

The utility model aims to provide a kind of pig mold that is easy to the demoulding.

This pig mold comprises the die body that is provided with the chamber groove; Four sidewalls of this chamber groove all have pattern draft; And the diapire of chamber groove is provided with the reinforcement that raises up; Its improvement is the edge line of the cross section of said reinforcement is designed to circular arc line, and the summit of this reinforcement is apart from the radius of the distance≤said circular arc line of bottom wall upper surface.

It has been generally acknowledged that when the cross section of reinforcement was designed to triangle, because this leg-of-mutton the right and left of formation all tilts and forms pattern draft, therefore this Cross section Design was to help the demoulding most.The application then thinks; Adopting under the application's the version, because that the height of reinforcement rises and falls is more mild, so can make mortar such as graphite more even in the surface distributed of reinforcement; Thereby help the demoulding; And because the surface area of reinforcement is bigger, can make mortar rapid draing, also help the demoulding; In addition, this structure also is difficult for producing the dead angle, has in the demoulding equally.

Checking shows, is adopting same mortar to carry out under the situation of jet mould, deviates from the groove of chamber if use the application's version then to be more conducive to iron block.

Be labeled as among the figure: die body 1, sidewall 1a, sidewall 1b, sidewall 1c, sidewall 1d, diapire 1e, chamber groove 2, reinforcement 3, edge line 301, distance H, radius R.

The specific embodiment

Embodiment 1

As shown in Figure 3, diapire 1e is provided with the reinforcement 3 that raises up, and the cross section of this reinforcement 3 is semicircle, and promptly the summit of reinforcement 3 is apart from the radius R of the distance H=said circular arc line of diapire 1e upper surface.Empirical tests is adopting same mortar to carry out under the situation of jet mould, and this version is designed to leg-of-mutton structure than the cross section with reinforcement and is more conducive to iron block and in the groove of chamber, deviates from.

Embodiment 2

As shown in Figure 4, diapire 1e is provided with the reinforcement 3 that raises up, and the edge line 301 of the cross section of this reinforcement 3 is a circular arc line, and the summit of reinforcement 3 is apart from the radius R of the distance H＜said circular arc line of diapire 1e upper surface.Empirical tests is adopting same mortar to carry out under the situation of jet mould, and this version is designed to leg-of-mutton structure than the cross section with reinforcement and is more conducive to iron block and in the groove of chamber, deviates from.

Claims

1. pig mold that is easy to the demoulding; Comprise the die body (1) that is provided with chamber groove (2); Four sidewalls (1a, 1b, 1c, 1d) of this chamber groove (2) all have pattern draft; And the diapire (1e) of chamber groove (2) is provided with the reinforcement (3) that raises up, and it is characterized in that: the edge line (301) of the cross section of said reinforcement (3) is a circular arc line, and the summit of this reinforcement (3) is apart from the radius (R) of distance (the H)≤said circular arc line of diapire (1e) upper surface.
