Description

Technical Field

[0001] This utility model relates to the field of wax model processing technology, specifically to an automatic wax model tree assembly and cleaning system. Background Technology

[0002] With the continuous improvement of industrial automation, especially in the field of precision casting, the production process of wax patterns is gradually developing towards high efficiency, precision, and intelligence. The assembly and cleaning of wax pattern trees are crucial steps in the precision casting process. Traditional wax pattern tree production processes often rely on manual operation and cleaning, resulting in low efficiency, poor precision, high labor intensity, and unsatisfactory working environments. These problems not only affect production efficiency but may also lead to fluctuations and inconsistencies in product quality.

[0003] In the production of wax models, the creation of a wax model tree requires welding multiple wax models together to form a specific structure, which serves as the basis for subsequent casting processes. The welding operation demands high precision in temperature control, posture control, and welding accuracy. Traditional manual operations often cannot guarantee high accuracy and consistency, easily leading to uneven welding, temperature instability, and other problems that affect the overall product quality. After welding, the wax model tree needs to be cleaned to remove excess wax and impurities to ensure the smooth progress of subsequent casting processes. Traditional cleaning processes typically involve manual handling and manual cleaning, which is inefficient and can easily cause excessive labor intensity for operators.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an automatic wax model tree assembly and cleaning system. Utility Model Content

[0011] As a preferred technical solution, the tree-assembly workbench includes a fixed workbench and a horizontal rotary workbench. The two types of workbench are suitable for two different tree stringing mold heads, which improves the flexibility of the system. Both types of tree-assembly workbench are equipped with fan groups to accelerate the solidification of the welding parts.

[0012] As a preferred technical solution, the crucible loading platform and the gating platform are respectively double-layer and triple-layer reciprocating loading mechanisms.

[0013] As a preferred technical solution, the robot is equipped with a hot knife with a temperature control system. The hot knife can be quickly switched through a quick-change disc and is equipped with a high-temperature cleaning system for periodically cleaning residual wax residue.
