Sliding block injection molding mechanism

Abstract

The invention discloses a sliding block injection molding mechanism. The sliding block injection molding mechanism comprises an injection molding main controller, a lower die base, an upper die base and a withdrawn die jacking mechanism, and the upper die base and the lower die base are jointed in the die closing process to form a die groove corresponding to more than one sliding block. Particularly, an insert module composed of a side pushing air cylinder, a pushing pin and an insert holder is arranged in the position, corresponding an embedding hole of the sliding blocks, of the lower die base; the side pushing air cylinder is fixedly connected to the outer wall of the lower die base; the pushing pin is integrated with the insert holder; the insert holder is separated from the die groove in an opening die state, is loaded with an insert, and is driven by the side pushing air cylinder to move towards the die groove in a closed die state and to ensure that the inset and the embedding hole are integrated. Due to the application of the injection molding mechanism, when the sliding blocks after injection molding are not cooled, the insert is embedded into the embedded hole of the sliding blocks automatically by the insert module, secondary fusing embedding or reassembling in the traditional technology can be omitted, and product forming degree and pass percent are improved. The sliding block injection molding mechanism is fast and convenient to use and low in cost and facilitates mass production.

Description

technical field [0001] The invention relates to an injection molding processing equipment for a special slider for automobiles, in particular to an efficient injection molding mechanism applied to the slider. Background technique [0002] Generally speaking, the injection mold consists of two parts, the upper mold base and the lower mold base, and the upper and lower mold bases are installed on the injection molding machine. During injection molding, the base of the upper mold and the base of the lower mold are closed to form a pouring system and a cavity. When the mold is opened, the base of the upper mold and the base of the lower mold are separated to take out the plastic product. [0003] In the prior art, it often involves an injection molding workpiece that needs to be embedded with accessories. First, injection molding is performed through an injection mold, and then the workpiece is partially dissolved and embedded into the accessories through heating and other proce...
