Automatic ejection device of three-plate mold pin-point gate

Abstract

The invention discloses an automatic ejection device of a three-plate mold pin-point gate. The automatic ejection device comprises a static mold base plate, a gate stripper plate, a movable mold cavity plate, guide positioning pins, an ejection assembly and a pouring sleeve. The gate stripper plate is located between the static mold base plate and the movable mold cavity plate, and the gate stripper plate, the static mold base plate and the movable mold cavity plate are connected through the guide positioning pins in a positioned mode. On one hand, the ejection assembly is connected with the static mold base plate, and on the other hand, the ejection assembly is hinged to the gate stripper plate. The pouring sleeve is connected with the static mold base plate. The ejection assembly is composed of locking blocks, sliding blocks, compression springs and push rods. In the mold opening process, a pin-point gate can be ejected off a mold rapidly and accurately, and a guarantee is provided for full-automatic production.

Description

technical field [0001] The invention belongs to the technical field of cable tie injection mold automation, in particular, the invention relates to an automatic pop-up device for a thin nozzle of a three-plate mold. Background technique [0002] In the process of cable tie injection molding production, three-plate molds are often used. During the injection molding production process of three-plate molds, there are generally the following three operation methods for taking out the fine nozzle: the first is manual operation, and the mold clamping mechanical equipment is in a semi-automatic state. After each mold is opened, the thin nozzle is taken out manually. This method has low production efficiency, high labor costs, and low safety factor, which is easy to cause industrial accidents. The second method uses the inertia of mold opening to shake the fine nozzle. The reliability of the method is poor, and the next mold clamping failure is often caused because the fine nozzle i...

[0002] In the process of cable tie injection molding production, three-plate molds are often used. During the injection molding production process of three-plate molds, there are generally the following three operation methods for taking out the fine nozzle: the first is manual operation, and the mold clamping mechanical equipment is in a semi-automatic state. The removal of the fine nozzle is done manually after each mold opening. This method has low production efficiency, high labor costs, and low safety factor, which is likely to cause industrial accidents. The second method uses the inertia of mold opening to shake the fine nozzle. The reliability of the method is poor, and the next mold clamping failure is often caused because the fine nozzle is not separated from the mold, and the automatic production cannot be continued; the third method is to use the robot to take out. Although this method is reliable, it can simultaneously take the product and the fine nozzle. Expensive, not popular yet and increase production costs of enterprises
