Description

Technical Field

[0001] The utility model relates to the field of molds, and in particular to a gate processing structure of an electronic injection mold. Background Art

[0002] Electronic injection molds are molds used to produce plastic parts for electronic products. Since electronic products usually require high precision, high quality and complex structures, the design and manufacture of electronic injection molds need to be particularly delicate and strict.

[0003] In electronic injection molds, the design of gates and runners is particularly important. Reasonable gate design can ensure that the plastic melt is evenly and stably filled into the mold cavity to avoid defects such as bubbles and shrinkage holes. The design of the runner needs to consider factors such as the fluidity of the plastic, filling speed, and pressure loss to ensure that the plastic can flow smoothly from the nozzle of the injection molding machine into the mold cavity.

[0004] However, in the existing gate processing structure of electronic injection molds, a large amount of material is easily generated in the runner and the gate during the injection molding process, thereby causing unnecessary waste of raw materials.

[0005] Therefore, it is very necessary to invent a gate processing structure for an electronic injection mold. Utility Model Content

[0007] Preferably, a plurality of ejector holes and ejector holes 2 are provided on the cavity seat body; the ejector holes are located in the corresponding main cavity and auxiliary cavity, and are connected with the corresponding main cavity and auxiliary cavity, and the ejector holes are coaxial with the corresponding main cavity and auxiliary cavity; the ejector hole 2 is located in the corresponding gate, and is connected with the corresponding gate, and the ejector hole 2 is coaxial with the gate.

[0008] Preferably, a corresponding ejector pin is slidably mounted in each ejector pin hole on the mold cavity seat body.

[0010] Preferably, a corresponding ejector pin No. 2 is slidably mounted in each of the ejector pin holes No. 2 of the mold cavity seat body.

[0011] Preferably, the mold cavity seat body and each ejector pin are each provided with a wiring hole for routing the ultrasonic probe.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The utility model saves the trouble of opening the runner as a whole by setting up the main mold cavity, the sub-mold cavity and the gate, and enables the material to directly enter the sub-mold cavities through the main mold cavity. In this way, it avoids the retention of runner agglomerates in the runner, thereby reducing the waste of materials and making the overall injection molding process more efficient.
