Ordered mold opening structure for multicolor molds

Abstract

The invention provides an ordered mold opening structure for multicolor molds, belongs to the technical field of molds, and solves the technical problems of multiple mold opening procedures and low efficiency in traditional mold structures. The ordered mold opening structure for the multicolor molds comprises a movable mold base plate, a fixed mold, and a movable template arranged between the movable mold base plate and the fixed mold; the fixed mold is hinged with a fixed mold pull hook for interlocking the movable template and the fixed mold; the movable mold base plate is hinged with a movable mold pull hook for interlocking the movable mold base plate and the movable template when the fixed mold and the movable template are located in a released mode; a first hoisting structure for driving the movable mold pull hook to swing to relieve locking when the fixed mold and the movable template are closed and bonded is fixedly arranged on the fixed mold; and a second hoisting structure for driving the fixed mold pull hook to swing to relieve locking when the movable mold base plate moves away from the fixed mold is fixedly arranged on the movable mold base plate. The ordered mold opening structure for the multicolor molds can realize quick and continuous opening of the multicolor molds to achieve higher efficiency.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a sequential mold opening structure of multi-color moulds. Background technique [0002] With the increase in car purchases, consumers have higher and higher requirements for the diversification of car appearance. Car lampshades and interior trims are mostly decorated with three-color trims, which are produced with three-color injection molds during the production process. The existing three-color injection mold drives the rotating core to rotate through the rotating shaft, so that the rotating cavity of the three core cavities performs multi-color injection molding. [0003] The Chinese patent with the authorized notification number CN204109244U discloses a three-plate mold for die-casting, including a static mold cover A, a static mold cover B, and a moving mold cover arranged in sequence from top to bottom, and the three-plate mold also includes a hook Block and A plate locking...

AI Technical Summary

Problems solved by technology

[0004] The structure of the above-mentioned mold is simple, but in the mold opening process, another structure needs to be installed on the fixed mold to control the separation of the locking block to realize the mold opening, which requires many procedures and low efficiency

In the initial injection molding and rotation process of multi-color molds, it is necessary to ensure the locking effect of the movable platen and the bottom plate of the movable mold, and in the injection molding process, it is also necessary to ensure the locking effect of the movable platen and the fixed mold. How to reasonably and quickly realize the locking effect control of the two areas It is a technical problem for those skilled in the art. In order to solve the above problems, the technical personnel in the field generally choose to use a light sensor to cooperate with the driving mechanism, and to control the locking structure according to the operating conditions of the mold to realize locking and unlocking. However, this The method is easily affected by the external environment and lacks stability
