Tool for solving problem that movable material of steel casting die is difficult to strip

Abstract

The invention discloses a tool for solving the problem that a movable material of a steel casting die is difficult to strip, and relates to the technical field of stripping tools. The problems that when an annular steel casting in the prior art is stripped, the die is prone to being damaged, the steel casting is prone to being damaged by knocking, and the yield of steel casting production is reduced are solved. The tool for solving the problem that the movable material of the steel casting die is difficult to strip comprises a die bottom shell, and the die bottom shell is inserted into a die outer shell. When the device is used for stripping the steel casting, only a linkage rod needs to be lifted or rotated through a cross rod, the linkage rod can drive the die bottom shell to ascend through a linkage clamping block at the bottom of a track disc, so that the steel casting is separated from the die outer shell and a die inner shell for demolding, the die outer shell and the die inner shell are protected against damage, the stripped steel casting is complete and cannot be damaged by knocking, and the use is convenient; and when the linkage rod is rotated, the height of the die bottom shell can be changed, so that casting manufacturing of steel castings with different thicknesses is realized.

Description

technical field [0001] The invention belongs to the technical field of mold ejection tools, and more specifically relates to a tool for solving the difficulty in ejection of mold live materials for steel castings. Background technique [0002] Steel castings refer to parts made of cast steel, which are similar in performance to cast iron, but stronger than cast iron. Cast steel is divided into three categories: cast carbon steel, cast low alloy steel and cast special steel. Cast steel is cast in a mold Manufactured in the same way, after the steel casting is cooled and formed, it can be taken out of the mold to proceed to the next production process. [0003] For example, the patent application number is: CN201710521128.6, which discloses a production method of low-carbon, low-alloy, high-strength, high-low temperature ductile steel castings, which is used to produce chemical components that meet: C: 0.16wt% ~ 0.24wt%, Si ≤0.60wt%, Mn≤1.20wt%, P≤0.04wt%, S≤0.045wt%, the pro...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a tool for solving the difficulty in removing molds for steel casting mold live materials, to solve the problem that the existing circular steel castings are difficult to separate from the mold after cooling and forming in the mold, and usually require Only by lightly vibrating and knocking the mold can the steel casting be separated from the mold. This method is easy to damage the mold, deform the mold, and affect subsequent use, and it is easy to damage the cast steel when the steel casting is lifted by the above method. parts, reducing the yield rate of steel castings, and the problem of low practicability
