Abstract

The invention provides a dislocation prevention sand core which comprises an upper box and a lower box, wherein the upper box is provided with a splitting angle. The sand core can be prevented from being dislocated and reversely arranged, and products can be avoided being scrapped, so that the production cost is reduced.

Description

A kind of anti-dislocation core

Technical field

The present invention relates to casting field, be specifically related to a kind of anti-dislocation core.

Background technology

It is columniform in the existing casting process part core being arranged, and it is not allow careless the rotation that certain structure is arranged in the above, but the cylinder core is not easy to locate, and is easy to rotation and causes part-structure deflection, causes product rejection.The core that also has has the branch in reverse side front, and the operator is often put back core because seeming symmetry up and down, causes the entire product structural change to be scrapped, and has improved production cost.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of anti-dislocation core, can prevent counter the putting of core dislocation, avoids scrapping of product, reduces production costs.

For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of anti-dislocation core, comprise top box, nowel, and described top box is provided with splits the angle.

As preferably, described splitting on the core print that the angle is located at top box.Be beneficial to the staff observation place, anti-dislocation is effective.

Beneficial effect:

The present invention adopts technique scheme that a kind of anti-dislocation core is provided, and has prevented counter the putting of core dislocation, has avoided scrapping of product, has reduced production cost.

The specific embodiment

Embodiment one:

As depicted in figs. 1 and 2, a kind of anti-dislocation core comprises top box 1, nowel 2, and the core print of described top box 1 is provided with splits angle 3.This core is cylindrical core, and product rejection has been avoided in splitting the angle and can not cause core deflection on the core print, has reduced production cost.

Embodiment two:

As shown in Figure 3 and Figure 4, a kind of anti-dislocation core comprises top box 1, nowel 2, and described top box 1 is provided with splits angle 3.Because have only top box 1 to split angle 3, when the operator is put back accidentally, will fail to lay down core because of the existence of splitting angle 3, avoided scrapping of product, reduced production cost, and simple to operate.

Claims

1. an anti-dislocation core comprises top box (1), nowel (2), and it is characterized in that: described top box (1) is provided with splits angle (3).

2. a kind of anti-dislocation core according to claim 1 is characterized in that: the described angle (3) of splitting is located on the core print of top box (1).
