Description

Technical Field

[0001] This utility model relates to the field of automated injection molding, and in particular to a fixture for automatically shearing sprue nozzles. Background Technology

[0002] In the field of sprue removal for injection molded products, manual trimming with knives or sprue pliers is commonly used. Air shear trimming involves a robotic arm removing the product, which is then manually placed onto a fixture, and the air shears are simultaneously cut off multiple sprues by stepping on the switch. However, the consistency of manual trimming is difficult to control; overly smooth sprues result in product defects, and excessive residual material can affect customer assembly. In such cases, manual trimming cannot guarantee consistent sprue height. Therefore, the current practice is to manually cut with scissors first and then smooth with a knife. This not only increases the labor intensity of workers but also increases production costs. To improve production efficiency and product quality while reducing worker labor intensity, automated equipment is needed to automate the cutting operation. This would not only improve production efficiency and quality stability but also reduce labor costs and waste of labor resources. Utility Model Content

[0012] In the above technical solution, the technical effect of this utility model is as follows: This utility model improves the efficiency of sprue cutting for plastic parts. The new automatic sprue cutting fixture adopts multiple mounting bases and air shears to adjust the distance between the air shear and the product, effectively solving the problem of high sprue residue.
