Core-pulling method of die-casting machine

Abstract

The invention discloses a core-pulling method of a die-casting machine. The core-pulling method comprises the steps that S1, a spraying mechanism sprays a release agent into a die cavity; S2, equipment sends out a die closing signal, a driving device drives a sliding block mold core to enter the die cavity in place, meanwhile, the spraying mechanism blows air into the die cavity, and the sprayingmechanism resets after air blowing is finished; S3, a die closing mechanism drives a movable die core for closing; S4, an injection mechanism injects raw materials into the die cavity; S5, the die closing mechanism drives the movable die core for opening; S6, the driving device drives the sliding block mold core to reset; and S7, a product is taken out for the next cycle. The inserting action of the sliding block mold core and the air blowing action of the spraying mechanism are conducted at the same time, the two procedures are integrated into one procedure, the core-pulling time is shortened, meanwhile, other actions cannot be affected, the product quality can be guaranteed, and the period is shortened.

Description

technical field [0001] The invention relates to a mold, in particular to a core-pulling method for a die-casting machine. Background technique [0002] In the prior art, the cantilever connectors of automobile engines are molded in a die-casting machine. During this process, the cantilever connectors need to be core-pulled. The core-pulling is to use the external raw material feeding system, release agent spraying system, and air blowing system. , A series of functions of die-casting machine forming. However, in the current production, the core pulling time is long, which prolongs the production cycle of the entire connector. In order to shorten the core pulling time, the effect of changing the operation such as fast feeding, fast spraying and blowing is not ideal, and it will also lead to the accumulation of raw materials. , Uneven spraying, moisture drying, etc., make the efficiency of core pulling lower, and the quality of connectors will also decline. Contents of the ...
