Description

Technical Field

[0001] The invention relates to the technical field of model processing, in particular to a basin-type gypsum model and a processing technology thereof. Background Art

[0002] CAM-assisted processing refers to the use of computer-aided technology to assist the processing process. Specifically, it is to achieve automated manufacturing through CAM software and CNC machine tools. CAM technology covers all production preparation activities from product design to processing and manufacturing, including CAPP, NC programming, calculation of labor quotas, formulation of production plans, formulation of resource demand plans, etc. CAM technology has a wide range of applications, covering multiple industries such as automobiles, aerospace, and electronics. It not only improves production efficiency and product quality, but also reduces human errors and production cycles, significantly improving the competitiveness and economic benefits of enterprises. Therefore, with the development of the times, the application of CAM-assisted processing has become more and more extensive.

[0003] In the actual production process, a set of basin plaster models usually consists of a concave fan model, a convex fan model, and a ring plate. During the processing, the machine tool needs to calibrate each model separately, and when processing a single component, double-sided processing is required according to the slight angle of the model. However, since each component is processed separately, it is difficult to accurately control the processing effect between the components, and certain errors will occur, resulting in a low degree of matching when the models are combined after processing. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a basin-type plaster model and a processing technology thereof, and the technical solution is as follows:

[0005] A basin-type plaster model consists of a convex fan model, a concave fan model and a ring plate model, wherein the ring plate model is located between the convex fan model and the concave fan model.

[0006] Preferably, an original tire is arranged on the top of the ring plate model, the convex fan model and the opposite side of the original tire are in contact with each other, and the concave fan model and the opposite side of the original tire are in contact with each other.

[0007] Preferably, the ring plate model fits the convex fan model and the concave fan model.

[0008] Preferably, positioning grooves are provided on all four sides of the interior of the concave fan model, and positioning pins corresponding to the positions of the positioning grooves are provided inside the concave fan model.

[0009] Preferably, the concave fan model and the ring plate model are provided with grooves on the side close to the convex fan model, and the convex fan model is provided with a positioning block corresponding to the position of the groove and matched in size on the side close to the concave fan model.

[0011] S1: First, the side of the concave fan model away from the convex fan model is processed, and after the processing is completed, the model is flipped over, and the front side of the model is processed after flipping. At this time, the front side of the model includes the part of the front side of the concave fan model that is not covered by the original tire and the front side of the original tire;

[0012] S2: After the front processing of the model is completed, a release agent is applied to the fitting position of the concave fan model and the ring plate model on the opposite side. After applying the release agent, gypsum is poured at the position of the ring plate model. After the gypsum is set, the side of the ring plate model close to the convex fan model is processed;

[0013] S3: After the processing of the ring plate model is completed, a release agent is applied to the side of the original tire close to the convex fan model and the exposed part of the upper part of the ring plate model. After applying the release agent, gypsum is poured on the position of the convex fan model. After the gypsum is set, the side of the convex fan model away from the concave fan model is processed;

[0014] S4: After the processing of the side of the convex fan model away from the concave fan model is completed, the convex fan model and the ring plate model are separated, the position of the original tire is processed, the original tire is removed, and the remaining part is the processed concave fan model.
