Description

Technical Field

[0001] The utility model relates to the field of plastic molds, in particular to a labor-saving nozzle material ejecting mechanism. Background Art

[0002] Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection, blow molding and low-foaming molding, and the sprue material mainly refers to the molding of the gate and runner outside the product. These sprue materials are formed during mold casting, which not only affects the appearance but is also difficult to separate.

[0003] For example, in a patent of a sprue material ejection mechanism for a plastic mold (Announcement No.: CN207915849U), it includes a mold base, a fixed plate, a mold core, a cover plate, a filling port, and a ejection mechanism. The top right side of the mold base is integrally formed with a fixed plate and the top of the mold base is provided with a mold core. The middle right side of the cover plate is provided with a filling port and the bottom is connected to the front side of the top of the mold base through a hinge. The fixed plate is provided with an L-shaped groove. The ejection mechanism is installed in the L-shaped groove on the fixed plate and is located directly below the filling port. The utility model has a simple structure and a reasonable design. The ejection mechanism can easily cut off the connection between the mold body and the sprue material and automatically eject the sprue material, which is very convenient and time-saving.

[0004] The above patent saves time and effort through the mold base and the ejection mechanism, which is very convenient. In daily use, the ejection mechanism is installed at the bottom of the filling port, causing the staff to be blocked by the ejection mechanism during the plastic pouring process, and the plastic fluid in the filling port will flow into the ejection mechanism, thereby affecting the operation of the ejection mechanism. The staff needs to clear the plastic in the ejection mechanism before ejecting the water outlet material, which reduces the ejection efficiency of the device. Therefore, it is necessary to invent a labor-saving water outlet material ejection mechanism to solve the above problems. Utility Model Content
