Machining process of disc tooth-shaped mold cavity

Abstract

The invention relates to a machining process of a disc tooth-shaped mold cavity. The process comprises the following steps: (1) a tooth gap is calculated according to the size of a workpiece to be machined; (2) if the tooth gap is less than 2 mm, the tooth number is reduced according to integral multiples from 2, and a new tooth gap is increased by multiples until the new tooth gap is more than 2 mm; (3) integral multiples of tool electrodes are produced with the integral multiples, calculated in the step (2), as number and with the new tooth gap as tooth space; and starting teeth of the tool electrodes are respectively from tooth number 1 to integral multiples of the tooth number; and (4) the different tool electrodes produced in the step (3) are used for respectively machining mold cavities. The new tooth gap calculated in the step (2) is in an optimal range of 2-3 mm. The process is skillful in design, convenient for machining of the tool electrodes and low in equipment requirements, guarantees the machining precision and the machining cost of the disc tooth-shaped mold cavity, and radically solves the machining difficulty of the disc tooth-shaped water filter piece mold cavity.

Description

technical field [0001] The invention relates to the field of injection mold processing, and more specifically, relates to a processing method for a cavity of a disk-toothed mold. Background technique [0002] Today, saving water resources is the common pursuit of the international community, and sprinkler irrigation and drip irrigation technology can save a lot of water resources and are widely used in agricultural production. In most areas, the water used for sprinkler irrigation and drip irrigation is directly taken from rivers. In order to reduce the pollution to the soil, it is necessary to filter the sediment in the water during sprinkler irrigation and drip irrigation. At present, this kind of filtration mostly adopts water filters of various shapes in sprinkler irrigation and drip irrigation equipment, and the water filter of disc tooth type is the most commonly used shape. The tooth grooves of the disk-toothed water filter are gradually narrowed and widened from the...

Problems solved by technology

However, there are more problems as follows: First, the milling machine has high requirements for processing equipment, and usually requires a high-speed machining center with a spindle speed of more than 40,000 rpm

However, this kind of tool has a small diameter and a large amount of wear during work, resulting in a low pass-through rate of the processing tool electrode.

Third, even if sophisticated equipment and tools are used, it is easy to produce deviations in production, making it difficult to guarantee the consistency of the tooth shape, which in turn leads to a high scrap rate of tools and tool electrodes, resulting in a substantial increase in costs
