Description

Front mould side core-pulling mould with front and rear limiting function

Technical Field

The utility model belongs to the technical field of dies, and particularly relates to a front die side core-pulling die with front and rear limiting.

Background

In the design process of the injection mold, because the side wall of the injection product is provided with a hole site, the product cannot be directly separated from the mold, an oil cylinder core-pulling mechanism is needed, the mold must firstly perform core-pulling action, and after the inverted core-pulling and demolding of the hole site, the front mold and the rear mold of the mold can be separated.

In general, the core-pulling structure is formed by driving the core-pulling mechanism to move by using an oil cylinder, however, because larger injection molding pressure exists during injection molding, the injection molding pressure can be transmitted to the rubber surface of the core-pulling insert, the core-pulling insert can transmit force to the core-pulling wedge, and the core-pulling wedge generally causes the core-pulling insert to generate core-pulling movement through a certain core-pulling angle. Because the core-pulling angle exists, when injection molding pressure is large, the pressure can be transmitted to the movement direction of the core-pulling inclined wedge through the core-pulling angle part, and the movement of the core-pulling inclined wedge drives the core-pulling insert to retreat, so that the hole position of the production port is not communicated, and the defect of flash burrs is generated.

Disclosure of Invention

The utility model aims at: in order to solve the problem that when injection molding pressure is large, the pressure can be transmitted to the movement direction of the core-pulling inclined wedge through the core-pulling angle part, the movement of the core-pulling inclined wedge drives the core-pulling insert to retreat, and as a result, the hole site of the production port is not communicated, and the defect of flash burrs is generated, so that the front mold side core-pulling mold limited in front and back is provided.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a spacing front mould side loose core mould around, includes loose core slider, front and back stopper, time delay piece and hydro-cylinder, the hydro-cylinder bottom is provided with the pull rod, the pull rod is connected on the front and back stopper, front and back stopper inside wall is provided with the sliding block, be provided with the sliding tray on the slider of loosing core, sliding block sliding connection is in the sliding tray, the time delay piece is connected the both sides of stopper around, and its butt is in on the lateral wall of slider of loosing core.
