[0002] In the earphone casting process, the rough mold is the mold used to make the earphone casting mold. The shape and angle of the rough mold are crucial to the final casting result. In order to ensure that the earphone shape and features that meet the design requirements are cast, an adjustable rough mold adjustment device is required to adjust the position and angle of the rough mold, so as to more conveniently obtain the required shape and details during the production process.

[0003] However, the following problems still exist in actual use:

[0004] (1) In the existing rough prototype making tools, the template is placed on the processing table, and then the operator uses knife cutting, heating, grinding, etc. to process the template into a customized rough prototype. However, the existing rough prototype making tools cannot flexibly adjust the inclination angle of the workbench, which limits the accuracy of rough prototype making and the control of processing effects. In addition, the inability to adjust the inclination angle of the workbench leads to reduced visibility and operability of the processing area.

[0005] (2) The clamping plate used to fix the template in the existing rough template making tools cannot adapt to templates of different sizes, which will cause the position of the template on the clamping plate to be unstable, resulting in movement or vibration of the template during processing. In addition, the clamping plate clamps the template in the middle position, blocking the operator's operating space in the middle of the template.

[0006] To this end, the utility model introduces a draft prototype adjustment device for TWS earphone casting. Utility Model Content
