Detecting mechanism for sprue multi-material trimmer

Abstract

The invention discloses a detecting mechanism for a sprue multi-material trimmer. The detecting mechanism comprises a detecting driver, a sprue detector and a detector support, wherein the detector support is arranged below the detecting driver; the sprue detector is arranged below the detector support. The detecting mechanism can automatically detect the position of a sprue multi-material part without manual positioning of a trimming part when a part is installed; errors caused by a human factor are reduced; the operation time is shortened; the part is pressed flatly before detecting, so that the detection is relatively accurate, and the production efficiency and the production quality are improved.

Description

technical field [0001] The invention relates to a detection device for automatically detecting the position of multiple materials at the gate, which is used for a multi-material trimming machine at the gate. Background technique [0002] Injection molded parts are very common in our life. Most of the plastic products are completed by injection molding, and the processing method of injection molding will have the phenomenon of multiple materials in the gate, and the gate of some parts with relatively small size Not on the part itself, but on the connector, you just need to cut the part from the connector, but some large size parts gate on the part itself, so you need to gate out the excess scrap cut off. Some injection molds are designed with a shearing mechanism, but the design of the mold is more complicated, the cost is higher, and the production is more difficult. The program requirements for the injection molding machine are also quite accurate. However, most of the ga...

[0002] Injection molded parts are very common in our life. Most of the plastic products are completed by injection molding, and the processing method of injection molding will have the phenomenon of multiple materials in the gate, and the gate of some parts with relatively small size Not on the part itself, but on the connector, you just need to cut the part from the connector, but some large size parts gate on the part itself, so you need to gate out the excess scrap cut off

Some injection molds are designed with a shearing mechanism, but the mold design is more complicated, the cost is higher, and the production is more difficult, and the program requirements for the injection molding machine must be quite precise

However, most of the gate shears are artificially positioned and installed parts, so there are disadvantages that errors are prone to occur and installation time is too long
