Production device for casting castings and avoiding generating cavities in castings

Abstract

The invention discloses a production device for casting castings and avoiding generating cavities in the castings. The production device comprises a table frame and a third mold, wherein a first moldis pasted onto a right side of the middle of an upper surface of the table frame; a first bump is fixedly connected to the right side of a second mold; a lower surface of the third mold is closely glued to the second mold and the first mold; a first bolt is connected to the third mold in a penetrating manner; a feed opening is formed in a left side above the third mold; a water tank is reserved ata center position below the third mold; a second heat dissipation device is arranged on the right side above a heating rod; and the second heat dissipation device comprises a second heat conducting pipe, a second heat conducting block and a rubber handle connecting block. The production device for casting castings and avoiding generating cavities in the castings can conveniently process tubular castings, has relatively accurate mold mounting positions, can conveniently take out finished products, can avoid generating bubbles and cavities in the finished products, and can be cooled rapidly.

Description

technical field [0001] The invention relates to the technical field of casting casting, in particular to a casting casting production device for preventing the casting from generating cavities. Background technique [0002] Casting is a kind of metal processing technology that human beings have mastered earlier. Casting is a method of casting liquid metal into a casting cavity suitable for the shape of the part, and after it cools and solidifies to obtain parts or blanks. The metal forming objects obtained by the casting method have a wide variety of castings and are closely related to our lives, such as door handles, door locks, radiators, upper and lower water pipes, iron pots, gas stove racks and irons, etc. The method of casting The workload of casting processing is greatly reduced, but the general casting production equipment has the following shortcomings: [0003] 1. If the positioning setting is not set, it is easy to cause the dislocation of the mold, thereby reduc...

AI Technical Summary

Problems solved by technology

[0003] 1. If the positioning setting is not set, it is easy to cause the mold to be dislocated, thereby reducing the accuracy of the mold installation position;

[0004] 2. For example, the patent application number is CN201610326020.7 for a metal casting casting mold. The first template and the second template are connected in the slot, and the fixation is not firm enough. Although the installation and disassembly are relatively simple, the raw materials are easy to overflow and affect the quality of the finished product. ;

[0005] 3. For example, the patent application number is CN201520395125.9 for a fan casting mold. The structure of the fan is relatively complicated, and there will be various curved parts. Without heating equipment, the cooling speed of the raw material is fast, and the raw material cannot be completely The gaps are filled, resulting in cavities and air bubbles, which affect the finished product effect;

[0006] 4. Most of the casting molds are not equipped with cooling devices, and the complete cooling time of raw materials is relatively slow, thereby reducing work efficiency
