Problems solved by technology

[0004] The purpose of the present invention is to provide a casting mold that can limit and fix the size of the clamp to solve the problem in the above-mentioned background technology. The method of rapid cooling of iron has the disadvantage that the surface of the cold iron is not smooth, and the clamping of the suspension core also varies greatly in size due to the difference in pouring temperature of molten iron, which is not conducive to ensuring the accuracy of the castings between them, and is not conducive to the development of subsequent products.

Abstract

The invention discloses a casting mold capable of limiting and fixing the size of a clamping gap. The casting mold comprises a supporting base, a mold box and air holes, wherein a shock-absorbing baseis mounted above the supporting base; sleeves and vertical rods are mounted between the supporting base and the shock-absorbing base; the vertical rods are mounted at the upper ends of the sleeves; the air holes are formed in the surface of the upper end of a sealing cover; air pipes are connected with the upper ends of air needles; the tail ends of the air pipes are connected with external extending air pipes through connectors; suspension core mold slots are arranged inside the mold box; and the suspension core clamping gap is formed between the top ends of the suspension core mold slots. In the casting mold capable of limiting and fixing the size of the clamping gap, the sleeves and the vertical rods are combined to form an embedded structure, so that the embedded deformation between the sleeves and the vertical rods becomes larger and larger in the downward gravity process of the upper end of the shock-absorbing base; and at the time, shock-absorbing springs are in the contractedstate and capable of absorbing shocks and buffering the gravity of the upper end of the shock-absorbing base.

Description

technical field [0001] The invention relates to the related field of casting molds, in particular to a casting mold capable of limiting and fixing the size of a clamp.
