A mold for long cylindrical plastic parts with rotatable core

Abstract

The application discloses a mold for a long cylindrical plastic part with a rotatable core. The mold is a mold with a rotatable core, which is especially suitable for a long cylindrical plastic part, and can reduce the time when the long cylindrical plastic part is demolded. The mold opening distance and molding cycle. The core of this mold design is a part that can rotate along the arc line. When the mold is closed, the core rotates to the predetermined position. The core, the fixed mold seat plate and the fixed template are combined into a complete fixed mold part. After the mold is closed Start injection molding, cool down after injection molding, and open the mold after cooling. The mold opening distance between the fixed mold part and the movable mold part only needs to exceed the length of the plastic part plus the safety distance, and then rotate the core along the arc through its own mechanical device At a certain angle, the plastic parts in the mold cavity can be smoothly pushed out from the inside and fall into the plastic part collection box below. The mold of this design can effectively shorten the mold opening stroke, reduce the demand of the mold on the injection molding equipment to lengthen the mold opening stroke, save the space occupied by the equipment, and improve the efficiency of the equipment.

Description

Technical field [0001] The present invention relates to the fabrication of mold manufacturing and use, and more particularly to a hollow-shaped metal part of a rotatable core which requires processing of a long cylindrite member. Background technique [0002] The production of long cylindrical parts often requires the production of a long cylindrical parts. When designing the corresponding mold, the ready-made mold can lead to a large spacing of the model, and the mold operation requires a longer guide rail, indirectly leads to the equipment occupied factory space. The long-distance opening engagement mold causes the total time of the plastic parts. Therefore, we think if we can design a mold, when the plastic length cylindrical model does not require the mold to open a longer distance, thereby ensuring the rapid production of the model, and the equipment does not need to take a large space. Inventive content [0003] In order to solve the above problems. The present invention p...
