Embodiment Construction

[0017] see image 3 and Figure 4 , image 3 It is a schematic cross-sectional structure diagram of the mold clamping state of the injection mold of the present invention. Figure 4 yes image 3 The enlarged schematic diagram of the cross-sectional structure of the injection mold shown. The injection mold 2 includes a fixed mold 21 , a movable mold 22 , a mold frame 23 and an ejection mechanism 24 . The mold frame 23 is used to support the fixed mold 21 , the movable mold 22 and the ejection mechanism 24 . The fixed mold 21 is attached to the movable mold 22 to form a closed cavity 25 with a fixed shape. The ejector mechanism 24 is disposed between the mold frame 23 and the movable mold 22 , and partially passes through the movable mold 22 to reach the sealed cavity 25 .

[0018] The fixed mold 21 includes a certain mold frame 211 , a certain mold core 212 and a sprue system 213 . The fixed mold frame 211 includes a receiving frame 214 . The fixed mold core 212 is embe...

Abstract

The invention relates to an injection mold, in particular to the injection mold capable of automatically cutting a water slot. The injection mold comprises a fixed mold, a movable mold and an ejecting mechanism, wherein the fixed mold is matched with the movable mold to form an enclosed cavity; the movable mold comprises a water slot passage which is connected with the enclosed cavity; the ejecting mechanism comprises a demolding thimble which is an oblique thimble and passes through the movable mold and extends to the enclosed cavity and adjacent to the water slot passage; and the demolding thimble demolds a plastic product molded in the enclosed cavity and cuts the water slot which is connected with the plastic product. The injection mold saves the manpower for the production of the plastic product, reduces the processing procedure and cost of the plastic product and shortens the production period of the plastic product.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold which can automatically cut off a nozzle. Background technique [0002] Mold is an indispensable and important tool in injection molding. Injection molding is a processing method that injects hot-melt plastic material into a closed cavity with the required shape in the mold at high speed, and after the plastic material cools and solidifies, the mold is opened to eject the solidified plastic product to obtain a molded product. Since the injection molding processing method has the characteristics of low molding cost, short molding cycle, simple molding process and easy molding of plastic products with complex shapes, it is widely used in the field of plastic product applications. [0003] see figure 1 , is a schematic cross-sectional structure diagram of an injection mold clamping state in the prior art. The injection mold 1 includes a fixed mold 11 , a movable mold 12 , a ...
