Mechanical drilling equipment for mold machining

Abstract

The invention relates to the technical field of mold machining, and discloses mechanical drilling equipment for mold machining. The mechanical drilling equipment comprises a rack, a vertical feeding mechanism, a motor, a drill rod and a drill bit; the vertical feeding mechanism is in sliding fit with the side wall of the rack; the motor is arranged on the vertical feeding mechanism so as to enable the motor to ascend and descend along the vertical direction; and an output shaft of the motor is vertically downward. The drill rod is in shaft connection with the output shaft of the motor; a first cavity is formed in the drill rod; a piston mechanism moving up and down is arranged in the first cavity and moves upwards along with rotation of the drill rod; the drill bit is fixedly connected to the lower end of the drill rod; a second cavity is formed in the drill bit; and a plurality of material holes communicated with the second cavity are evenly distributed in the side wall of the drill bit. The second cavity is communicated with the first cavity; and when the drill bit drills holes, the piston mechanism moves upwards. According to the mechanical drilling equipment for mold machining, metal chippings adsorbed to the drill bit can be adsorbed in the drilling process, so that the drilling precision of the drill bit cannot be affected.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a mechanical drilling device for mold processing. Background technique [0002] When the mold is processed, it is often necessary to drill holes on the mold to meet the processing requirements, and drilling equipment is often used to drill the mold. [0003] At present, the drilling equipment used for mold processing generally includes a frame, a drilling mechanism, a vertical feeding mechanism, a drilling mechanism and a motor. The vertical feeding mechanism is connected with the drilling mechanism to make the drilling mechanism realize vertical Direction of feeding, the motor is connected to the drilling mechanism to realize the rotation of the drilling mechanism and then realize the drilling operation of the mold. [0004] But for some metal molds, since the drill bit of the drilling mechanism is mostly made of metal, the drill bit rotates at a high speed to drill the...

Problems solved by technology

[0004] But for some metal molds, since the drill bit of the drilling mechanism is mostly made of metal, the drill bit rotates at a high speed to drill the mold, and the metal mold is drilled and then there are metal debris, so that the drill bit rotates at a high speed. The static electricity generated during the process will cause metal debris to be adsorbed on the drill bit. As the number of drilling holes increases, more and more metal debris will be adsorbed on the drill bit, which will cause large errors in the subsequent mold drilling and affect the drilling. Accuracy, which will increase the risk of substandard mold processing
