Embodiment 1

[0070] Embodiment 1: the concrete structure of the present invention is: it comprises upper mold body, lower mold body, guide device and the position-limiting device that are positioned between upper mold body and lower mold body, set between upper mold body and lower mold body There are oblique gate cutting components and horizontal gate cutting components; when the upper mold body and the lower mold body move relative to each other, the oblique gate cutting components and the horizontal gate cutting components realize gate cutting synchronously.

[0071] When the oblique gate cutting assembly and the horizontal gate cutting assembly cut off the wiper gate, they have the advantages of fast cutting speed, crisp and neat cutting, and smooth and no sawtooth. At the same time, it has the ability to cut off the oblique gate of the wiper and the horizontal gate, and the cutting of the oblique gate and the horizontal gate is carried out synchronously, with a high degree of automation...

Abstract

The invention discloses a sprue cutting die for a windscreen wiper. The sprue cutting die comprises a bottom plate, wherein a circular transition seat, supporting blocks, at least two lever air cylinders and pressing blocks are arranged at the upper end of the bottom plate, and a positioning sleeve is coaxially arranged at the upper end of the circular transition seat; the pressing blocks are installed on the lever air cylinders, each supporting block is arranged under the corresponding pressing block, and the lever air cylinders are annularly arrayed around a center shaft of the round transition base. The invention aims to provide the sprue cutting die for the windscreen wiper, the traditional manual operation is replaced, automatic cutting of a sprue can be realized in the die, the production efficiency is improved, and the requirement for large-scale production is met.

Description

technical field [0001] The invention relates to a gate cutting mold of a wiper. Background technique [0002] The die-casting process mainly includes six stages: mold closing, filling, cooling, mold opening, and demoulding. These 6 stages directly determine the molding quality of the product, and these 6 stages are a complete continuous process. [0003] 1. Filling stage [0004] Filling is the first step in the entire die-casting cycle, starting from the time the die is closed to start die-casting until the die cavity is filled to approximately 95%. In theory, the shorter the filling time, the higher the molding efficiency; but in actual production, the molding time (or die-casting speed) is subject to many conditions. [0005] High speed filling. When filling at high speed, the shear rate is high, and the viscosity of the plastic decreases due to the effect of shear thinning, which reduces the overall flow resistance; the local viscous heating effect will also make the...
