Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding part post-processing technical field especially relates to a water gap device for electric tool shell production. BACKGROUND

[0002] In the manufacturing process of electric tool shell, injection molding technology is widely adopted due to its efficiency, high precision and suitability for complex structure forming. The injection molding machine forms the shell product by injecting molten plastic into the mold cavity and solidifying after cooling. In this process, the water gap in the gating system serves as a channel for molten plastic to flow into the cavity, and is an indispensable part of injection molding. In traditional process, water gap removal usually relies on manual trimming or mechanical cutting, but with the increasing demand for automation, the industry is gradually shifting to more efficient solutions.

[0003] Currently, for the automatic removal of water gap, the mainstream process uses ultrasonic separation technology. This technology drives the transducer through an ultrasonic generator to transmit high-frequency vibration to the water gap area of the mold. The heat generated by the vibration softens the plastic at the water gap connection, thereby achieving rapid separation of the water gap and the injection molding part. Compared with traditional mechanical cutting, ultrasonic separation has the advantages of non-contact, high efficiency, smooth cut, etc., and is widely used in the production of precision injection molding parts such as electric tool shell.

[0004] However, the existing ultrasonic separation process still has significant defects. During the separation process, the water gap and the injection molding part usually fall together into the collection device due to synchronous separation from the mold, resulting in mixing of the two. This phenomenon forces the production link to add an additional manual sorting step, which not only reduces overall efficiency but also increases labor costs. In addition, improper human operation during the sorting process may cause scratches on the surface of the shell or water gap residue, affecting product yield. SUMMARY
