Device for automatic blanking of three-plate mold spreader channel cold slug

Abstract

The invention discloses a device for automatic blanking of a three-plate mold spreader channel cold slug. The device provided by the invention comprises a sliding spreader plate (1), prodding rods (2) and a material pulling plate (02). The device is characterized in that the sliding spreader plate (1) which can horizontally slide and is provided with prodding inclined holes is arranged under the material pulling plate (02) of a three-plate mold; the sliding spreader plate (1) is arranged corresponding to a channel of a movable mold core; the prodding rods (2) which are bended are arranged at a lower part of a fixed mold; lower ends of the prodding rods (2) are inserted into the prodding inclined holes of the sliding spreader plate (1); and through utilization of separation of the fixed mold and the material pulling plate (02) in mold unloading, the prodding rods (2) prod the sliding spreader plate (1) to slide horizontally so that the connection between a product and a cold slug located at a spreader channel is released. The device solves the problem that the prior art has the defects of high labor consumption, high costs, low efficiency and large labor intensity, and realizes the purpose of labor-saving, low-cost, high-efficiency and low-labor intensity separation of a three-plate mold spreader channel cold slug and a product through automatic blanking of the three-plate mold spreader channel cold slug.

Description

technical field [0001] The invention relates to a material cutting mechanism of the cold material head of an injection mold, specifically refers to an automatic cutting material of the cold material head of the three-plate mold branch channel used for the automatic disconnection of the cold material head of the injection mold branch channel of the three-plate structure and the product mechanism. Background technique [0002] The injection mold with three-plate structure is called three-plate mold for short. The so-called three-plate mold refers to an injection mold with a fixed mold, a moving mold and a drawing plate. The drawing plate is a part that uses the mold opening to remove the cold slugs of the main channel and the sub-runner from the gate. After the cold slug is pulled out from the gate, the cold slugs of each sub-runner are still connected to the product. The prior art The products are cut off one by one from the cold slug heads of the numerous runners manually t...

AI Technical Summary

Problems solved by technology

In actual production, the cold material head is cut off by manual random duty, which requires a lot of labor, high work intensity, high cost, and low efficiency. Therefore, the existing technology has problems and deficiencies such as labor-intensive, high cost, low efficiency, and high work intensity.
