Rotatable mold for long cylindrical plastic part of mold core

Abstract

The invention discloses a rotatable mold for a long cylindrical plastic part of a mold core. The rotatable mold for the mold core is particularly suitable for the long cylindrical plastic part, the mold opening distance of the mold during demolding of the long cylindrical plastic part can be reduced, and the forming period of the mold during demolding of the long cylindrical plastic part can be shortened. The mold core designed by using the mold is a component capable of rotating along the circular arc, the mold core rotates to the predetermined position during mold closing, and the mold core,a fixed mold seat plate and a fixed mold plate are combined into a complete fixed mold part; injection molding is started after mold closing is finished, cooling is carried out after injection molding is completed, mold opening is carried out after cooling is completed, the mold opening distance of the fixed mold part and a movable mold part only needs to exceed the length of the plastic part plus the safety distance, then the mold core rotates by a certain angle along the arc through a mechanical device of the rotatable mold, and the plastic part in the mold cavity can be smoothly pushed outfrom the inside and falls into a lower plastic part collection box. By the adoption of the rotatable mold, the mold opening stroke can be effectively shortened, the requirement of the mold on the increase of the mold opening stroke of the injection molding equipment is reduced, the occupied space of the equipment is saved, and the efficiency of the equipment is improved.

Description

technical field

[0001] The invention relates to the field of mold manufacture and use, in particular to a mold for a long cylindrical plastic part with a rotatable core and used for processing the long cylindrical plastic part. Background technique

[0002] In the production of plastic parts, it is often necessary to produce long cylindrical plastic parts. When designing the corresponding mold, the ready-made mold will lead to a large distance between the mold opening and the model, and the mold operation requires a long guide rail, which indirectly causes the equipment to occupy a large space in the factory. Longer distance of mold opening and closing will lead to longer total processing time of plastic parts. Therefore, we think about whether we can design a mold that does not need to open and close the mold for a long distance when making the injection molding long cylindrical model, so as to ensure the rapid production of the model, and the equipment does not need to occ...

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] The invention provides a mold for a long cylindrical plastic part with a rotatable core. Aiming at the current conventional mold injection molding of a long cylindrical plastic part, the distance between the mold opening and the plastic part is relatively large, and the mold operation requires a long guide rail, which indirectly As a result, the equipment takes up a lot of space in the factory, and the longer distance of mold opening and closing will lead to a longer total time for plastic parts processing. The design of such a mold for long cylindrical plastic parts with a rotatable core adopts a rotating core, that is, when the mold is opened, when the core is out of the cavity hole, the core rotating disk is quickly rotated so that the axis of the core is in line with the cavity. The axis of the cavity hole in the movable mold is misal...
