Positioning and taking-out device for movable types in die cavity

Abstract

The invention relates to a positioning and taking-out device for movable types in a die cavity. The positioning and taking-out device comprises a die, the movable types, positioning grooves, positioning magnets and a strong magnetism handle. The positioning groove is formed in the die cavity. The positioning magnets are arranged at the bottoms of the movable types, the movable types are arranged in the positioning grooves, and the strong magnetism handle is used for taking the movable types arranged in the positioning grooves out. According to the provided positioning and taking-out device for the movable types in the die cavity, the ordinary magnets are used for positioning the movable types, it can be guaranteed that the movable types are not brought out by a sand core in the normal core manufacturing process, the complex procedures that when core manufacturing and drawing are conducted every time, the movable types are brought out, and installation needs to be conducted again are reduced, the powerful magnets are used for taking out the movable types, flexible replacement of the movable types in the die cavity is achieved, field operation is convenient, and the core manufacturing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of moulds, and in particular relates to a device for positioning and taking out movable type in a mold cavity. Background technique [0002] When producing castings, some customers need marking information such as production date and part number on the castings. However, these information are changing information. When making molds, change the corresponding marking information on the mold by making movable type and replacing movable type. . When the mold is actually used, the type positioning and replacement take up a considerable part of the time. [0003] At present, the general practice is to process movable type, process movable type positioning grooves in the mold cavity, and directly install movable type in the positioning grooves. In this way, the movable type will be taken out together with the sand core every time the core is made and molded. Since the production date is changed every day, it does not need ...

AI Technical Summary

Problems solved by technology

In this way, the movable type will be taken out together with the sand core every time the core is made and molded. Since the production date is changed every day, it does not need to be replaced every time. The movable type is taken out and reinstalled every time the mold is lifted. Makes the operation more cumbersome and greatly reduces the efficiency of mold core making
