Wax mold welding device used for precision casting and welding method of wax mold welding device

Abstract

The invention discloses a wax mold welding device used for precision casting. The device comprises a working box with an opening formed in the upper end, two clamping mechanisms are arranged in the working box, each clamping mechanism comprises a clamping box, and the clamping boxes are slidably connected between a partition plate and the inner side wall of the working box; and horizontally-arranged threaded rods are rotatably connected to the inner side walls of the clamping boxes, two sections of threads with opposite rotating directions are arranged on each threaded rod, clamping sleeves are connected to the two sections of threads of each threaded rod in a threaded sleeving manner, connecting blocks are fixedly connected to the side walls, close to the center of the working box, of thetwo clamping sleeves of each threaded rod, and the connecting blocks penetrate through the side walls of the clamping boxes in a sliding manner and are fixedly connected with movable plates. By arranging the clamping mechanisms, it can be simultaneously guaranteed that wax molds on the two sides are always located in the middles of the clamping boxes after being clamped, and then the welding precision is higher; and through the arrangement of an adjusting mechanism, simultaneous and multi-directional heating can be achieved through multiple spray heads, and the welding efficiency is greatly improved.

Description

technical field [0001] The invention relates to the related technical field of wax mold manufacturing and home processing equipment, in particular to a wax mold welding device and a welding method for precision casting. Background technique [0002] Wax patterns are a common casting method. Investment casting is mainly composed of mold manufacturing, wax mold manufacturing, shell mold manufacturing and subsequent drying, roasting, pouring, solidification and other processes. Among them, the joining of wax molds is an extremely important step. The accuracy of wax mold joining will affect the subsequent finished products. The accuracy is greatly affected. [0003] However, the general process of welding wax models is to manually heat the workpiece with a soldering iron block to dissolve the wax models, and then manually assemble the wax models. Due to the low accuracy of manual operation, it is easy to cause the degree of dissolution of each wax model Inconsistencies and ina...
