Precision casting die for production of steel wire sleeve of ship

Abstract

The invention discloses a precision casting die for production of a steel wire sleeve of a ship, and belongs to the technical field of dies. The precision casting die for production of the steel wire sleeve of the chip comprises two lower die shells. A lower die cavity is formed in the top of each lower die shell. The bottom of each lower die cavity is fixedly connected with a threaded column. The outer wall of each threaded column is connected with a parting core through threads. Sealing gaskets are fixedly connected to the left side and the right side of the top of each lower shell correspondingly. The bottoms of the two lower die shells are connected with bolts through threads correspondingly. The two sets of bolts penetrate through the tops of the sealing gaskets. The tops of the sealing gaskets are fixedly connected with upper die half shells through the bolts correspondingly. The precision casting die for production of the steel wire sleeve of the ship is reasonable in design; and the lower die shells, the upper die half shells, the threaded columns and the like are adopted, so that in the process of separating the lower die shells from a cast die body, the parting cores are directly separated from the die body, a specific tool for taking out the parting cores is not needed any more, the product quality is not affected accordingly, and the production efficiency of products is improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a precision casting mold for the production of ship steel wire sleeves. Background technique [0002] Steel wire sleeves used on ships are generally cast, and precision casting (referred to as precision casting) is required. During precision casting, a wax mold must be produced first. The two parting modules can be taken out directly, but the parting parts in the wax mold The mold core is not easy to take out, and a specific workpiece needs to be used to take it out, which not only increases the difficulty of taking out the piece, but also damages the inner wall of the wax mold, which affects product quality and production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a precision casting mold for the production of ship wire sleeves, to solve the problem that the parting core in the mold proposed in the above background technolo...
