Technical Field

[0001] The utility model relates to the technical field of wax injection machines, in particular to a vertical double-station direct injection wax injection machine. Background Art

[0002] Wax patterns are a commonly used casting method. Investment casting mainly consists of processes such as mold manufacturing, wax pattern manufacturing, shell mold manufacturing, and subsequent drying, baking, pouring, and solidification. A wax pattern is a pattern used to form the cavity of a casting. To obtain castings with high dimensional accuracy and surface finish, the wax pattern itself should first have high dimensional accuracy and surface finish. A wax injection machine is a device for making wax patterns.

[0003] In the prior art, a patent document with the publication number CN215144435U discloses a new type of fully automatic wax injection machine, including a workbench. One side of the workbench is fixedly installed with a material receiving box by welding. The inner wall of the bottom of the material receiving box is fixedly installed with a buffer sponge by welding. The top of the workbench is fixedly installed with two symmetrical vertical plates by welding. First chutes are opened on one side of the two vertical plates. The same fixed plate is slidably installed in the two first chutes. The top of the fixed plate is fixedly installed with a wax injection tank by welding. The bottom of the fixed plate is fixedly installed with an upper mold by welding.

[0004] During use, it is found that when the above device processes wax patterns, it is necessary to move a set of wax patterns out of the mold and then process another set of wax patterns, resulting in low wax pattern processing efficiency. Summary of the Utility Model
