Description

Glue feeding structure for improving product glue opening height

Technical Field

The utility model belongs to the technical field of advance gluey mould, especially, relate to an improve gluey structure of advancing that product jiao kou was drawn high.

Background

The plastic mold is a combined plastic mold for compression molding, extrusion molding, injection, blow molding and low foaming molding, and mainly comprises a female mold with a variable cavity and formed by a female mold combined substrate, a female mold component and a common plastic mold picture clamping plate of a common plastic mold picture combined by the female mold, and a male mold with a variable core and formed by a male mold combined substrate, a male mold component, a male mold combined clamping plate, a cavity cutting component and a side cutting combined plate. And the coordination change of the male die, the female die and the auxiliary forming system of the die. Can process series plastic parts with different shapes and sizes. Description of injection molding Process: a mold is a tool for producing plastic articles. It is made up of several sets of parts, and the combination has a moulding cavity. During injection molding, a mold is clamped on an injection molding machine, molten plastic is injected into a forming mold cavity and is cooled and shaped in the cavity, then an upper mold and a lower mold are separated, a product is ejected out of the mold cavity through an ejection system and leaves the mold, finally the mold is closed again for next injection molding, and the whole injection molding process is carried out in a circulating mode. In the existing injection molding process, for column products, because the top glue feeding is most suitable, a traditional glue feeding mode is generally designed, a glue opening can change along with factors such as product material, wall thickness, hole number and the like, a better molding effect is often desired to be obtained, the glue opening can be controlled to be about D0.5-D1.5, but due to the limitation of a mold structure at the glue opening, a good cooling effect is difficult to achieve, the glue opening is overheated, and a drawing-up phenomenon often occurs, particularly, the phenomenon of drawing-up of a test mold in the production of column top glue feeding or side brush pen type latent glue feeding (such as electronic cigarette type cigarette mouth products and the like) is frequent, and when the phenomena occur, if the structural limitation of a client product cannot be optimized, only cooling time can be prolonged or hot pressing treatment can be performed through a jig. When the single amount of the product is small, the product can be processed manually or by a jig, but when the product is produced in large scale, the method wastes time and labor, and the condition needs to be improved.
