Mold device for producing alternator claw pole

Abstract

The invention discloses a mold device for producing an alternator claw pole. The mold device comprises an upper mold fixing plate and a lower mold fixing plate. An upper punch, a mold separating pull rod and an annular wedge are mounted on the upper mold fixing plate. An upper semi die and a die resetting spring are mounted outside the mold separating pull rod. A lower semi die and a stopping block are mounted on the lower mold fixing plate. A guide column is mounted in the lower semi die, guide positioning between the lower semi die and the upper semi die is realized through the guide column. A lower punch is mounted in the lower semi die. A lower punch pad is mounted under the lower punch. An upper die pad and a lower die pad are mounted in the middle of the lower mold fixing plate. A pressing rod is mounted in the lower die pad. A locked module resetting pull rod is mounted on the stopping block. The stopping block is connected with a locked module through the locked module resetting pull rod. A locked module resetting spring is mounted outside the locked module resetting pull rod. Material utilization rate is high, and producing efficiency is high.

Description

technical field [0001] The invention relates to a mold device for producing alternator claw poles. Background technique [0002] At present, there are mainly three types of alternator claw pole production and molding: [0003] 1. The disadvantage of open mold forming is that edge trimming is required, and the subsequent cutting process is large, the material utilization rate is low, the product is scrapped more, and the dimensional accuracy is poor. [0004] 2. The disadvantages of precision casting are low production efficiency, defects such as porosity, shrinkage cavity, and segregation on castings, low magnetic flux density, low power generation, and poor dynamic balance, which need to be corrected. [0005] 3. Closed mold forming, the product accuracy and production efficiency are improved compared with the previous two, but it can only be used for products without chamfering, and the chamfering needs to be completed by cutting, and the material utilization rate is low....
