Lower mold and upper mold of power plug as well as mold assembly

Abstract

The invention discloses a lower mold of a power plug. The lower mold comprises a lower mold body, a first module is arranged at the back end of the lower mold body, three electrode plate molds of thepower plug are arranged at the front part of the first module, a second module is arranged at the front end of the lower mold body, at least two lower mold areas are arranged in the middle of the lower mold body between the first module and the second module, the lower mold area is a main lower mold of the power plug, multiple transversely arranged exhaust grooves are formed in the lower mold bodyoutside the lower mold area, a lower mold feeding hole is formed in the center of the lower mold body and communicates with a main feeding groove, the main feeding groove communicates with the lowermold area through a passing groove, a lower mold water inlet pipe and a lower mold water outlet pipe are arranged at the back end of the lower mold body separately, and the lower mold water inlet pipeand the lower mold water outlet pipe communicate with inlet and outlet ends of a lower mold water cavity in the lower mold body respectively. The structures of the upper mold body and the lower moldbody are matched. The mold in the scheme is simple in structure and low in cost, the production procedures are simplified during use, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of wire processing, in particular to a lower mold, an upper mold and a combination thereof for a power plug. Background technique [0002] Such as figure 1 As shown, the power plug has three electrodes, each electrode is provided with an insulating sheet, the length of the insulating sheet is greater than the exposed length of the three electrodes, the positive and negative electrodes 61 have the same structure, the positive and negative insulating sheets 62 have the same structure, and the grounding sheet 63 And the ground insulation sheet 64 has a special structure. For this kind of power plug product, the existing production method is divided into two production stages, the first is to produce three electrodes with insulating sheets, and the second is to produce power plug products. The way the product has the following flaws: [0003] (1) Three sets of independent molds need to be designed, the first set is pos...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the existing problems in the existing method of producing power plugs that three sets of independent molds need to be designed, the mold cost is high, the production time period is long, the work efficiency is low, the labor cost is high, the process is many, and the quality is difficult to guarantee.
