Wax pattern forming mould

Abstract

The invention discloses a wax pattern forming mould comprising a locking upper seat; an inward-concave first mounting cavity is formed in the bottom end of the locking upper seat; a forming female mould is arranged below the locking upper seat; the forming female mould is partially inserted into the first mounting cavity through an opening end of the first mounting cavity; a forming cavity used for forming a wax pattern matrix of a wax pattern is formed in the forming female mould; and the top end of the forming cavity is opened. A rib plate forming member is mounted in the first mounting cavity. The rib plate forming member comprises a first cover plate used for sealing the opening end of the forming cavity; and a plurality of rib plate forming movable blocks inserted into the forming cavity to form a plurality of rib plates are arranged on the first cover plate. A deep groove forming member used for forming a plurality of deep grooves are arranged on the first cover plate. The deep groove forming member comprises a plurality of deep groove forming movable blocks penetrating through the first cover plate to stretch in the forming cavity to form the deep grooves. A cam pushing mechanism for pushing the wax pattern upward out of the forming cavity at the time of demoulding is connected to the lower portion of the forming female mould.

Description

technical field [0001] The invention relates to the field of wax pattern forming, in particular to a wax pattern forming mold. Background technique [0002] The design and manufacture of wax molds have a great impact on precision castings, and directly affect the surface finish and dimensional accuracy of the wax molds after molding. Therefore, the wax molds must meet several requirements: 1) Ensure that the molded wax molds can reach Dimensional accuracy and surface roughness required by the design; 2) Easy assembly and disassembly, lightweight, durable, and easy mold removal; 3) Each part of the profiling should be easy to process. [0003] The structure of the wax mold of the inner ring of a certain guide that needs to be formed is shown in the attached figure figure 1 As shown, the wax model has 12 ribs 101 and 12 bosses 103, and there are deep grooves 102 between adjacent ribs 101. There are two existing methods of mold release: one is to make the cover plate into a c...
