Description

Technical Field

[0001] The utility model relates to the technical field of mold part processing, in particular to a device for processing mold parts. Background Art

[0002] The inclined hole is a special structure in the mold, and its axis is at a certain angle to the reference surface of the mold. The inclined hole mainly plays the role of guiding, positioning and exhaust in the mold. If the processing accuracy of the inclined hole is insufficient, it will cause deviations in the mold during mold closing, which will affect the size and shape of the product, resulting in reduced product quality, and then lead to increased scrap rate and production costs.

[0003] At present, the processing of inclined holes in molds is mainly carried out by machine tools. For example, the processing process of inclined guide pin holes in molds is as follows: first, the fixed mold plate of the mold is fixedly installed on the workbench of the milling machine, and its inclination angle is adjusted, and then points are made on the surface of the fixed mold plate. After the points are made, the center drill is used to make positioning holes at the positions of the points. After the positioning holes are made, the milling cutter is used to make countersunk holes on the surface of the fixed mold plate. After the above steps, the drilling process of the inclined guide pin holes in the fixed mold plate can be completed.

[0004] However, the Z-axis machining of ordinary three-axis is carried out in a direction perpendicular to the horizontal plane, and there is an inclination of 17 to 23° between the inclined guide column and the machining surface. When using this method for machining, three drilling tools are required in the process of dotting, drilling and countersinking. Errors will inevitably occur in the process of replacing drilling tools. Replacing drilling tools multiple times will lead to accumulated errors, resulting in poor machining accuracy of the machined inclined holes, which will affect the use of the mold. Utility Model Content

[0005] The utility model provides a device for processing mold parts to solve the technical problem in the prior art that the processing of inclined guide post holes requires multiple replacements of drilling tools, which causes error accumulation and leads to poor processing quality of the inclined guide post holes.

[0006] In order to solve the above problems, the device for processing mold parts provided by the utility model adopts the following technical solutions:

[0007] A device for processing mold parts, comprising:

[0008] A machine tool worktable, the top surface of which is equipped with an inclination fixture, and a machine tool spindle is installed above the machine tool worktable;

[0009] A slope fixture, the bottom surface of which is fixedly mounted on the machine tool workbench, and the top surface is used to mount the mold parts;

[0010] A centering step drill, which is mounted on the main spindle of the machine tool, and the drill bit of the centering step drill faces the worktable of the machine tool;

[0011] A numerical control controller is connected to the machine tool worktable and the machine tool spindle to accurately control the movement and processing of the two.

[0012] The beneficial effects of the device for processing mold parts provided by the utility model are as follows: by installing a centering step drill on the main spindle of a machine tool, the centering step drill is used to perform drilling processing on mold parts. The centering step drill has a centering step, which can provide reliable stability for the drill bit during use, effectively avoid the occurrence of drill tool deflection, and greatly improve the stability and accuracy of drilling; the special structural form of the centering step drill enables it to complete the processing of drilling holes inside mold parts and countersunk holes on the surface of mold parts without replacing the drill bit during the drilling process, avoiding the occurrence of error accumulation due to replacement of drilling tools, and ensuring the processing quality of inclined guide post holes. Through the above-mentioned settings, the utility model effectively solves the technical problem in the prior art that the processing of inclined guide post holes requires multiple replacements of drilling tools, resulting in error accumulation, thereby resulting in poor processing quality of inclined guide post holes.

[0013] Furthermore, the centering step drill comprises a clamping end, one end of which is mounted with the drill bit, and a centering step is provided between the clamping end and the drill bit.

[0014] Furthermore, a radial dimension of the centering step is larger than a radial dimension of the drill bit.

[0015] Beneficial effect: When the drill bit is subjected to cutting force and torque, it is easy to deviate. The radial dimension of the centering step is larger than the radial dimension of the drill bit. The centering step with a larger radial dimension can provide better support and stability for the drill bit, thereby reducing the deviation of the drill bit and achieving the purpose of improving processing accuracy.

[0016] Furthermore, the drill bit is a two-edged drill, a three-edged drill, or a four-edged drill.

[0017] Furthermore, the slope jig is a CNC slope jig.

[0018] Beneficial effect: The slope fixture adopts a CNC slope fixture, and the program can be used to accurately control the inclination angle of the slope fixture, thereby ensuring the processing angle of the inclined hole in the mold part and improving the production efficiency of the mold part.

[0019] Furthermore, the CNC inclination jig comprises a CNC turntable, the CNC turntable has an active disk and a locking disk, and a jig workbench is installed between the active disk and the locking disk.

[0020] Furthermore, the CNC turntable is a CNC four-axis turntable.

[0021] Beneficial effects: The CNC four-axis turntable can realize multi-axis linkage, making the slope adjustment of the slope fixture more flexible and efficient, greatly shortening the slope adjustment time, thereby reducing the time cost of mold parts processing.
