Problems solved by technology

[0006] 1. When using an injection molding machine to inject molten plastic or rubber into the mold, it is necessary to insert the nozzle of the injection molding machine into the gate of the mold, and then pull out the nozzle after pouring is completed, but part of the molten plastic will often remain when the nozzle is pulled out Or rubber, the residual molten plastic or rubber drips a

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 and figure 2 The feed-improved injection mold shown includes gating system 1, molding system 2 and base 3, gating system 1, molding system 2 and base 3 are connected sequentially from top to bottom, gating system 1 includes sprue 10, sprue sleeve 11 and the runner 12, the sprue sleeve 11 is set on the upper end of the gate 10, the sprue sleeve 11 is hollow inside and communicates with the gate 10, the runner 12 penetrates downward from the gate 10 to the cavity inside the molding system 2 . During injection molding, the nozzle of the injection molding machine is inserted into the gate 10 through the sprue sleeve 11 , and the molten plastic or rubber enters the molding system 2 through the runner 12 .

[0028] Such as image 3 As shown, the inner wall of the sprue sleeve 11 is provided with three layers of sealing films 110, and the three la...

Abstract

The invention discloses a feeding improved type injection mold. By means of sealing films disposed on the inner wall of a sprue bush, it is avoided that a nozzle of an injection molding machine takesout a molten raw material when being pulled out, and it can also be avoided that impurities enter a chamber of the mold. The feeding improved type injection mold of the technical scheme is characterized by comprising a pouring system, a forming system and a base, the pouring system comprises a sprue and a runner, the sprue bush is disposed at the upper end of the sprue, at least one sealing film is disposed on the inner wall of the sprue bush, the outer ends of the sealing films and the inner wall of the sprue bush are integrated, and the sealing films are made of a material with ductility andresilience. By means of the feeding improved type injection mold, it can be avoided by the sealing films disposed on the inner wall of the sprue bush that the nozzle of the injection molding machinetakes out molten plastic or rubber when being pulled out, the sprue or an external environment is prevented from being contaminated, it can also be avoided that impurities enter the chamber of the mold, and the precision and purity of injection molding products are ensured.

Description

technical field [0001] The invention relates to the field of mold design and manufacture, in particular to a feed-improved injection mold. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding is to make thermoplastic or thermosetting materials into plastic products of various shapes using plastic molding molds. Injection molding is realized through injection molding machines and molds. [0003] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. Injection molds are widely used in the compression molding or injection molding of engineering plastics, rubber, ceramics and other products. Injection molds have specific c...
