Dual-surface multifunctional combined casting die

Abstract

The invention discloses a dual-surface multifunctional combined casting die. The die comprises a casting die frame (1), inward steps (2) are arranged on the upper and lower end surfaces of the casting die frame (1), an embedded dual-surface shaping plate (3) connected to the casting die frame (1) is arranged at each step (2), and the inner wall of the casting die frame (1) and the end surfaces of the dual-surface shaping plates (3) define a casting cavity (4). The dual-surface multifunctional combined casting die has the advantages of simple structure, convenience in operation and reliability in use, and when the die is used, the dual-surface shaping plates can be changed conveniently and fast, the interchangeability is high, and by virtue of replacement, the shaping of different casting cavities can be finished rapidly, thereby being applicable to production of various products in batch and products of different shapes, enhancing the production efficiency greatly, simplifying manufacture of the casting die frame, and saving the manufacture cost.

Description

technical field [0001] The invention relates to a casting mold, in particular to a double-sided multifunctional combined casting mold. Background technique [0002] At present, in the existing casting sand box structure, its main structure includes a sand box capable of negative pressure extraction, and a mold cavity for the product to be cast is arranged in the sand box. [0003] In CN103736926A, an invention patent application titled "negative pressure lost foam sand box" is disclosed, which includes left wall, right wall, front wall, rear wall and bottom wall, on the left wall, right wall, front wall and rear wall A row of through holes arranged in the up and down direction and penetrating the wall of the negative pressure lost foam sand box are respectively formed, and at the same time, through holes arranged in the front and rear direction are also formed on the bottom wall, and a row of through holes is formed on both sides of each row of through holes. The first cyli...
