Embodiment 2

[0052] see Figure 1-Figure 4 As shown, when the gating system in the prior art cooperates with the molding system to produce injection molds, it will produce more sprue material. Specifically, as figure 1 , image 3 with Figure 4 As shown in , the sprue 1 and the runner 2, and the joints between the runner 2 and the product cavity 3 are the areas where the nozzle material is produced. The long melt flow path of the gating system with the existing structure leads to the generation of excessive nozzle material and product defects. Injection molding has a long filling cycle and low product production efficiency.

[0053] In order to solve the above problems, this embodiment is an improvement on the basis of the above embodiment 1, such as Figure 5-Figure 7 As shown, this embodiment improves the runner structure of the gating system. The runner of the gating system includes a main channel 1 and a sub-runner 2, wherein: the main channel 1 communicates with all the sub-runners...

Embodiment 3

[0068] This embodiment provides an injection mold, including a molding system and the above gating system. The molding system includes a product cavity 3 connected with the gating system.

[0069] The injection mold of this embodiment has the above-mentioned pouring system, so it also has the advantage of being able to separate the nozzle material and the product at the joint under the jacking action of the ejector system, thereby improving production efficiency.

[0070] As an optional embodiment, the injection mold further includes an ejection system for ejecting the product and / or nozzle material and a cooling system for cooling the mold.

[0071] The injection mold in this embodiment can mass-produce plastic products, mainly including four major systems;

[0072] Gating system: The feeding channel between the nozzle of the injection molding machine and the cavity becomes the gating system, which consists of the main channel 1, the runner 2 and the rubber mouth insert 4; th...

Abstract

The invention provides a pouring system and an injection mold with the same and relates to the technical field of injection molds. The technical problem of low separation efficiency of a water gap material generated in a pouring system and a product is solved. The pouring system comprises a shearing part and a submerged glue cavity connected with a runner and a product cavity, the submerged glue cavity is obliquely arranged relative to the feeding end of the product cavity, the shearing part is located outside the submerged glue cavity, and the shearing part is used for abutting against a water gap material in the submerged glue cavity to cut off the joint of the water gap material and a product when the product and / or the water gap material are / is ejected out through external force. The inclined submerged glue cavity is formed to communicate with the product cavity, the feeding ends of the submerged glue cavity and the product cavity are not positioned on the same horizontal line, sothat when an ejection system ejects the product or the water gap material, the shearing part abuts against the water gap material in the submerged glue cavity, the water gap material and the product can be separated from the joint under the ejection of the ejection system, the water gap material does not need to be cut manually, and production efficiency and quality of products are improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a pouring system and an injection mold with the same. Background technique [0002] Plastic parts are mainly obtained by forming molds, and their quality and cost depend on the structure, quality and service life of the mold. With the increasing demand for large, complex, precise, beautiful and long-life forming molds in various industries and the wide application of computer technology in the modern mold industry, the mold industry is developing in the direction of deepening theoretical knowledge, compounding subject knowledge, and actively updating technology , which puts higher requirements on the structure of injection molds. [0003] The bottom ring (bearing) plastic products used in the household air conditioner series cylindrical cabinets are mass-produced and formed through injection molds, see figure 1 with figure 2 as shown, figure 1 Injection molds in incl...
