Description

Technical Field

[0001] The present application relates to the field of wax molds, and in particular to a wax mold trimming machine for casting. Background Art

[0002] Wax patterns are a common casting method. Investment casting primarily consists of mold making, wax pattern making, shell mold making, and subsequent drying, firing, pouring, and solidification processes. The wax pattern forms the mold cavity of the casting. To achieve castings with high dimensional accuracy and surface finish, the wax pattern itself must possess high dimensional accuracy and surface finish. However, the factors affecting the dimensional accuracy of wax patterns during the wax pattern manufacturing process are complex, and the numerous process parameters result in a wide range of variation in dimensional accuracy.

[0003] Most of the existing trimming machines are unable to eliminate the odor generated when trimming wax models, which easily causes the odor to be emitted into the air, resulting in a problem that degrades the working environment. Utility Model Content

[0004] In order to achieve the above-mentioned objectives, the present application provides a wax mold trimming machine for casting.

[0005] The present application provides a wax pattern trimming machine for casting that adopts the following technical solution:

[0007] By adopting the above technical solution, when in use, the wax model is placed in the placement box and fixed by the clamping assembly, and then the suction hood is pushed to make the sliding block slide in the slide groove. When sliding the suction hood, the suction hood can be lifted by the telescopic rod, and the sliding block is slid into the slide groove so that the suction hood is located directly above the placement box. Then the trimming assembly is started to trim the wax model, and at the same time, the fan is started to absorb the odor generated during the trimming in the placement box, so that the odor is purified and discharged through the activated carbon filter, thereby avoiding the odor from being emitted into the air as much as possible, resulting in a deteriorated working environment.

[0011] By adopting the above technical solution, the position of the trimming column can be adjusted by sliding the first movable plate left and right on the base plate so that the trimming column is aligned with one of the through holes. Then, the second movable plate can be moved forward and backward to insert the trimming column through the through hole into the inner wall of the wax mold clamped in the U-shaped frame, so that the trimming column trims the inner wall of the wax mold.
