Description

Technical Field

[0001] The present invention relates to the technical field of wax mold processing, and specifically relates to a wax mold processing raw material mixer with a crushing structure. Background Technique

[0002] A wax mold is a model used to form the cavity of a metal casting during the casting process. By the fluidity of wax, the cavity is filled. When processing the wax mold, first, a crushing structure is used to crush the wax ingot into wax chips, and then it is mixed with liquid wax. A crushing structure is provided inside the wax mold processing raw material mixer;

[0003] For example, the Chinese utility model patent with the authorization announcement number CN218307676U discloses a raw material mixing device for wax mold processing. The raw material mixing device for wax mold processing includes a cylinder body. A first feeding port is provided on the upper side of the cylinder body, and a second feeding port is provided on the side of the cylinder body. During operation, the wax ingot enters through the first feeding port, and the liquid wax enters through the second feeding port. Then, after passing through the crushing device and the filtering component, the wax ingot becomes wax chips and enters the stirring mechanism, and then the mixture of the wax chips and the liquid wax is stirred to improve the uniformity and smoothness of the raw materials required for the wax mold. In the present invention, the settings of the first support plate, the second support plate, the filter plate, the first motor, and the cam in the filtering component can crush and filter the wax ingot before stirring, so that the wax ingot is crushed into wax chips, thereby improving the mixing effect of the raw materials;

[0004] For example, the Chinese utility model patent with the authorization announcement number CN221846804U discloses a raw material stirring device for wax mold processing, including a device component, a crushing component, a stirring component, and a separating component. The device component includes a device main body, a first feeding port, a connecting rod, a protective shell, and a driving motor. The crushing component includes a second feeding port, a crushing mechanism, a first filter screen, a first stirring rod, a crushing knife, and a first driving rod. The stirring component includes a second driving rod, a stirring rod, a bottom rod, a side rod, and an auxiliary rod. The separating component includes a second stirring rod, an extension rod, an auxiliary knife, a screening net, and a second filter screen. By arranging a second driving rod and a stirring rod below the driving motor, the wax chips and the liquid wax are preliminarily stirred and mixed. At the same time, the bottom rod and the side rod scrape the bottom and the side of the device main body to prevent the wax chips in the edge area from being unable to be mixed. At the same time, an auxiliary rod staggered with the stirring rod is also arranged to improve the stirring effect of the stirring rod and reduce the stirring time required;

[0005] Combined with the existing solutions and the actual production and processing uses, the existing wax mold processing raw material mixers with a crushing structure still have the following problems: The stirring efficiency needs to be improved. When feeding, when the temperature drops, the wax material solidifies and adheres to the liquid wax feeding pipe and the discharging pipe. If not cleaned for a long time, the wax material accumulated in the pipe affects the conveying efficiency of the wax material. Therefore, we propose a wax mold processing raw material mixer with a crushing structure to facilitate solving the problems raised above. Summary of the Invention
