Description

Injection molding device with duckbilled submarine gate

Technical Field

The utility model relates to an injection moulding device particularly, relates to an injection moulding device with duckbilled formula submarine gate.

Background

The injection molding is to make thermoplastic plastics or thermosetting materials into plastic products with various shapes by using a plastic molding die, and the injection molding is mainly realized by an injection molding machine and the die. The sprue is a feeding channel which is connected with the runner and the cavity in the injection mould.

The kind of the gate includes a sprue, a side gate, a submarine gate, and the like. The structure of the inclined subsurface flow channel of the existing submerged gate type injection mold is conical, and the glue inlet part is a round hole, so that the structure can cause large pressure loss and the tail end of a product is not filled fully.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an injection moulding device with duckbilled formula submarine gate has avoided pressure loss too big, leads to the terminal unsatisfactory problem of filling of product.

Therefore, the utility model provides an injection moulding device with duckbilled formula dive runner, including front mould mechanism and back mould mechanism, front mould mechanism includes front mould panel and front mould board, is provided with the runner cover in the front mould panel, and the runner cover is provided with the runner, is provided with front mould benevolence on the front mould board, and back mould mechanism includes the back template, is provided with back mould benevolence on the back template, wears to be equipped with on the back mould benevolence and inlays needle and thimble, and the guiding gutter on the needle is inlayed to the oblique latent runner intercommunication of runner, and the oblique latent runner tip is duckbilled formula structure.

Furthermore, two inclined submerged flow passages which are symmetrically arranged are arranged on the flow passage.

Further, the rear die mechanism further comprises a rear die panel, a die pin and a thimble seat, the rear die plate and the rear die panel are supported through the die pin, the thimble seat is further arranged between the rear die plate and the rear die panel, and the insert pin and the thimble are fixedly installed on the thimble seat.

Furthermore, the thimble seat includes thimble panel and thimble bottom plate, and thimble panel fixed mounting is on the thimble bottom plate.

Furthermore, a positioning ring is arranged on the front die panel and is coaxially arranged with the sprue bush.

Furthermore, a locking module is arranged on one side of the front mould mechanism.

The utility model provides an injection moulding device with duckbilled formula submarine gate, injection moulding device adopt ejector pin formula submarine gate. During injection molding, the front mold mechanism and the rear mold mechanism are closed, the positioning ring enables the mold to be concentric with a gun nozzle of the injection molding machine, molten plastic in a runner enters a cavity formed by the front mold core and the rear mold core from an inclined submerged runner through a diversion trench on the insert needle, and injection molding of a product is completed. Due to the adoption of the duckbilled submarine gate, the opening area of the glue inlet part is large, the pressure loss is small, and the phenomenon that the tail end of a product is not fully filled is avoided. The submarine gate is arranged on the ribs and columns which can not be seen on the surface of the product, so that spray marks and air lines caused by spraying can not be left on the surface of the product during molding, and the injection molding quality of the product is high. During the branch mould, because inlay needle length and be greater than the thimble, when the thimble seat went upward, the inlay needle directly cuts off the submarine gate and is connected with the product, and duckbilled formula submarine gate increases the width under the condition that does not change submarine gate thickness, consequently though advance gluey department opening area grow, but the thickness that the inlay needle cut off is inconvenient, does not influence the normal work of inlay needle.

The utility model provides a pair of injection moulding device with duckbilled formula submarine gate reduces loss of pressure through adopting duckbilled formula submarine gate, guarantees the terminal effect of moulding plastics of product.
