Mold for in-mold placement of hardware for large switch handle

Abstract

The utility model relates to injection mold field discloses the mold of large -scale switch handle in -mold placement hardware spare, this mold includes upper die seat board, cavity board, core plate and lower die seat board, adds the middle die plate between cavity board and core plate. The positioning pin or positioning recess for placing hardware spare is equipped with on the core, and the through -hole or recess corresponding with the positioning structure is set up on the middle die plate. When closing the mould, the core and the middle die plate form the upper and lower clamping and lateral package to hardware spare, solve the problem that hardware spare shifts because uneven stress in injection. In addition, the ejection mechanism driven by the cylinder controlled by the controller is used to the mold, solve the problem that the large plastic part is difficult to demould because of the big tight force. The utility model realizes the high-precision, high-strength stable clamping of the hardware spare in the mold and the powerful and smooth ejection of the large plastic part through the above structure, and the product qualification rate and production stability are improved significantly.
