Abstract

The utility model discloses a prevent mould structure of hole site fault relates to die casting die's technical field. Prevent die structure of hole site fault includes lower bolster and two at least mould posts, and two mould posts all place on the lower bolster, and the axial lead of two mould posts coincides each other, and two minor diameter ends of mould post are butt each other, and two major diameter ends of mould post deviate from each other, and the terminal surface of the minor diameter end of one of them mould post is outside protruding along the axial lead direction, and the terminal surface of the minor diameter end of another mould post is inside sunken along the axial lead direction, and protruding and sunken shape cooperatees. The mode of mutually supporting is sunken through the arch of one end and the other end for the laminating part laminating intensity in the middle of two moulds is strengthened, can guarantee that two mould posts can not take place relative displacement when aluminium liquid strikes, thereby has avoided appearing disconnected poor phenomenon in the product hole, and then has avoided follow-up process of polishing to the hole, and then has promoted the output efficiency of product.

Description

Prevent mould structure of hole site fault

Technical Field

The utility model relates to a die casting die's technical field especially relates to prevent die structure of hole site fault.

Background

In the die casting die of current aluminium system product, if there is a longer hole in the middle of the product, then need place a mould post respectively on die casting die both sides, thereby two mould posts butt form the mould post of a whole root of cylinder between die casting die to just can form a hole in the product when casting.

The butt joint face of present two mould posts is the plane, and when the mould was filled into to fused aluminium liquid, liquid can assaulted the position of the butt of two mould posts for butt part can remove in the middle of two mould posts, thereby makes the product hole that the die-casting was come out have the offset.

At present, a method for processing the offset is to make a hole smaller than a target aperture, and then polish the hole by using a drill bit matched with the target aperture, so that an additional process is added for the production of products, the labor cost and the time cost are both greatly increased, and the product output efficiency is low.

SUMMERY OF THE UTILITY MODEL

The technical scheme of the utility model a prevent hole site fault's mould structure is provided, thereby can avoid the production of disconnected difference to improve the output efficiency of product. The technical scheme is as follows:

the utility model provides a prevent die structure of hole site fault, including lower bolster and two at least mould posts, two mould posts are all placed on the lower bolster, and the axial lead of two mould posts coincides each other, and two mutual butts of minor diameter end of mould post, two major diameter ends of mould post deviate from each other, and the terminal surface of the minor diameter end of one of them mould post is outside protruding along the axial lead direction, and the terminal surface of the minor diameter end of another mould post is inside sunken along the axial lead direction, and protruding and sunken shape cooperatees.

The mode of mutually supporting is sunken through the arch of one end and the other end for the laminating part laminating intensity in the middle of two moulds is strengthened, can guarantee that two mould posts can not take place relative displacement when aluminium liquid strikes, thereby has avoided appearing disconnected poor phenomenon in the product hole, and then has avoided follow-up process of polishing to the hole, and then has promoted the output efficiency of product.

Specifically, the mould structure for preventing hole site faults comprises four mould columns, and the mould columns are matched in a pairwise opposite mode.

Compared with the prior art, the utility model beneficial effect who has is: the mode of mutually supporting is sunken through the arch of one end and the other end for the laminating part laminating intensity in the middle of two moulds is strengthened, can guarantee that two mould posts can not take place relative displacement when aluminium liquid strikes, thereby has avoided appearing disconnected poor phenomenon in the product hole, and then has avoided follow-up process of polishing to the hole, and then has promoted the output efficiency of product.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Thereby improve the output efficiency of product in order to avoid the production of offset, the technical scheme of the utility model provides a prevent the mould structure of hole site fault. The technical scheme is as follows:

the invention is explained in further detail below with reference to fig. 1 to 3.

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a prevent die structure of hole site fault, including lower bolster 3 and two at least mould posts 2, two mould posts 2 are all placed on lower bolster 3, the axial lead of two mould posts 2 coincides each other, two little diameter end mutual butts of mould post 2, two major diameter ends of mould post 2 deviate from each other, the terminal surface of the minor diameter end of one of them mould post 2 is outside protruding 4 along the axial lead direction, the terminal surface of the minor diameter end of another mould post 2 is along the inside sunken 5 of axial lead direction, protruding 4 cooperatees with the shape of sunken 5.

The mode of mutually supporting is mutually supported through the arch 4 of one end and the sunken 5 of the other end for the laminating part laminating intensity of the centre of two moulds is strengthened, can guarantee that two mould posts 2 can not take place relative displacement when aluminium liquid strikes, thereby has avoided appearing disconnected poor phenomenon in the product hole, and then has avoided follow-up process of polishing to the hole, and then has promoted the output efficiency of product.

Specifically, prevent hole site fault's mould structure includes four mould posts 2, and two liang of cooperation of being opposite of mould post 2.

Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
