Description

Technical Field

[0001] This utility model belongs to the field of mold processing technology, and in particular relates to a CNC milling machine for mold processing. Background Technology

[0002] CNC milling machines are mechanical equipment used for machining parts, such as cutting connecting plates and drilling molds. Molds are tools used for punching, extrusion, and pressure casting to ensure that the produced objects have a consistent shape and facilitate mass production.

[0003] A search revealed a CNC milling machine for mold processing disclosed in patent publication number CN221871236U. Addressing the problem that existing CNC milling machines for mold processing can only clean up dust generated during processing, leaving some larger debris residue on the worktable and affecting subsequent processing, the following solution is proposed: The machine includes a housing. A first fixed plate is fixedly mounted on one side of the housing, and a first motor is fixedly mounted on the first fixed plate. A transmission shaft is fixedly connected to the output shaft of the first motor, and a first sprocket and a first fan blade are fixedly mounted on the transmission shaft. A controller is fixedly mounted on one side of the housing, and an air inlet is provided on one side of the housing. This design can clean up both dust and debris generated during processing, preventing dust and debris from affecting the health of workers and subsequent processing.

[0004] The aforementioned CNC milling machine for mold processing has a machining component located on the top of its housing. The machining component, a first motor, and a second motor are all electrically connected to a controller. However, it is inconvenient to adjust the position of the machining component on the horizontal plane, and the machining component is located above the mold processing position, which could cause workers to be accidentally injured by the machining component during mold handling, reducing safety during mold processing. Furthermore, its fixing mechanism includes a second fixing plate fixedly installed on one side of the housing. A second motor is fixedly installed on the second fixing plate, and a bidirectional threaded rod is fixedly installed on the output shaft of the second motor. Four support columns are fixedly installed on the bottom inner wall of the housing, and a worktable is fixedly installed on each of the four support columns. Two moving rods are threaded onto the bidirectional threaded rod, and clamping plates are fixedly installed on the sides of the two moving rods that are close to each other. One of the two moving rods has an L-shaped rod fixedly installed at its top. A water tank is fixedly installed at the top of the housing, with a water inlet at the top. A water pipe is fixedly installed on the inner wall of the top of the housing, with one end of the water pipe connected to the water tank and a nozzle fixedly installed at the other end. Through holes are opened on both sides of the water pipe, and the L-shaped rod is slidably installed in the two through holes. The L-shaped rod has a water outlet. After the mold is processed, the controller starts the second motor and stops clamping the mold. At the same time, the L-shaped rod moves so that the water outlet is located in the water pipe. Water washes the debris on the worktable through the nozzle, and the sewage is discharged through the drain. However, during the mold processing, it is not convenient to clean the debris on the worktable at the same time. The debris on the worktable can only be cleaned after the mold is removed, and the machine may even need to be stopped, which will reduce the processing efficiency of the mold.

[0005] To address these issues, we provide a CNC milling machine for mold processing. Utility Model Content
