Intelligent secondary fixed die releasing injection molding die structure

Abstract

The invention relates to the technical field of dies, and particularly relates to an intelligent secondary fixed die releasing injection molding die structure. The intelligent secondary fixed die releasing injection molding die structure comprises a heat insulation board, a panel, a pushing rod bottom plate, a fixed die pushing rod fixing plate, a supporting plate, a fixed die plate and a movabledie plate which are sequentially arranged from top to bottom, wherein a fixed die embedding part and a fixed die mold core are mounted in the fixed die plate; a movable die embedding part is mounted in the movable die plate; the fixed die mold core is sleeved with the fixed die embedding part; a movable mold core which is fixedly connected to the supporting plate sleeves the fixed die mold core; and a plurality of pushing rods are mounted at the bottom part of the pushing rod bottom plate and penetrate the fixed die pushing rod fixing plate, the supporting plate, the fixed die plate and the fixed die mold core. The intelligent secondary fixed die releasing injection molding die structure further comprises a hot runner pouring system. The intelligent secondary fixed die releasing injectionmolding die structure is simple and novel; the hot runner pouring system and the pushing rods are arranged at the fixed die side, such structure is opposite to a general die structure; and the outer surface of a loudspeaker-shaped cover is prevented form pushing rod and pouring port marks.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an injection mold structure for fixed mold intelligent secondary demoulding. Background technique [0002] figure 1 , figure 2 as well as image 3 The plastic part shown is a loudspeaker horn cover of an electronic product, the maximum external dimension is 133mm×118mm×26mm, the material is ABS, and the shrinkage rate is 0.5%. There are 800 cylindrical holes with a diameter of 2mm on the speaker cover, of which the through hole and the blind hole each account for half, the depth of the blind hole is 2.2mm, and the length of the through hole is 3.6mm. The requirements on the outer surface of the horn cover are very high, no traces of push rods and gates are allowed, and molding defects such as weld marks, flow marks, silver streaks and poor filling are not allowed; the current mold structure, the push rod is at the movable mold, and the pouring The system is at the fixed mold,...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems of the prior art, the present invention provides a fixed mold intelligent secondary demoulding injection mold structure, which is advanced, reasonable, novel and practical, and the hot runner pouring system and the push rod are arranged on the side of the fixed mold, contrary to the conventional mold structure, Realize that there are no traces of push rods and gates on the outer surface of the horn cover, and there are no molding defects such as weld marks, flow marks, silver streaks, and poor filling
