Description
Technical Field
The utility model relates to the technical field of injection molds, in particular to a large-stroke core pulling device for an injection mold and the injection mold.
Background
When the plastic product is provided with a through hole, a groove and a boss, the plastic product cannot be directly taken out from the die, and the forming parts of the forming holes, the groove and the boss are made into movable parts, which are called movable cores. The mechanism for completing the extraction and resetting of the movable core is called a core pulling mechanism, and the molded part which can prevent the injection molding part from demolding can be separated from the injection molding part before the mold opening action is completed through the core pulling mechanism.
At present, the common core pulling mechanism on the injection mold mainly comprises the following two types:
1. the mould is provided with an inclined guide pillar which is connected with the movable core, and the power of opening and closing the mould drives the inclined guide pillar to move so as to drive the movable core to slide, thus the movable core is completed to loose core or reset.
2. The mould is provided with a hydraulic oil cylinder, and the movable core is driven to slide in the mould by the hydraulic oil cylinder, so that core pulling or resetting of the movable core is realized.
For some products with longer core pulling stroke, if the mold is designed in the first mode, the thickness of the mold needs to be thickened, which can certainly increase the manufacturing cost of the mold, and larger injection molding equipment is needed to finish the processing; otherwise, if the die is not thickened, the inclination angle of the inclined guide post needs to be increased, so that the inclined guide post has a larger breaking risk in the processing process. If the mould is designed in the first mode, the hydraulic cylinder with larger driving stroke is required to be additionally arranged on the mould, the mould cost is certainly increased, and the hydraulic cylinder needs to be injected with oil in the injection molding process, so that the injection molding period is long, and the processing efficiency is affected.
In conclusion, for products with longer core pulling stroke, when designing the mold, the core pulling mechanism on the existing injection mold either thickens the mold, or increases the inclination angle of the inclined guide post, or increases the hydraulic cylinder; moreover, these three approaches have some drawbacks.
