Plastic mold provided with sequential closure mechanism

Abstract

The invention relates to a plastic mold provided with a sequential closure mechanism. The plastic mold comprises a fixed mold fixing plate, a fixed mold cavity plate and a mold core fixing plate matched one another and also comprises a slide block translational mechanism and the sequential closure mechanism, wherein the slide block translational mechanism comprises a slide block locking plate, theslide block locking plate is slidably connected to a slide part in a matched manner, the slide part can translate laterally, and a formed bump is formed in the side surface of the slide part; the sequential closure mechanism comprises a main body of the closure mechanism, a first positioning bar and a second positioning bar; the first and second positioning bars are separately inserted into the main body of the closure mechanism from the upper part and the lower part, the main body of the closure mechanism is provided with a slide block capable of moving horizontally if being stressed, the first positioning bar is provided with a locking port where the slide block is locked, and the top end of the second positioning bar extrudes the slide block, so that the slide block is separated from the locking port. The plastic mold provided by the invention is simple in structure, easy to guarantee the processing precision, simple in assembly process, relatively small in size, high in gap precision, relatively small in occupied mold space, stable in structure and relatively long in service life.

Description

technical field [0001] The invention belongs to the field of molds, in particular to a plastic mold with a sequential locking mechanism. Background technique [0002] Molds are needed in the manufacturing process of plastic products, and for various plastic products, the corresponding mold structures are also varied. In the production process of some plastic products with specific structures, it is necessary to use molds with sequential mold opening and closing functions. [0003] In some existing mold structures, the function of opening and closing molds in sequence is generally realized through the swing rod structure, which makes the overall structure of the mold scattered, large in size, and difficult to install; at the same time, it is difficult to control the installation gap of the big and small molds, and there is often a large gap The problem is that the precision is insufficient, the stability is poor, and the matching structure is easy to wear, loosen or even fai...

[0003] In some existing mold structures, the function of opening and closing molds in sequence is generally realized through a swing rod structure, which makes the overall structure of the mold scattered, large in size, and difficult to install; at the same time, it is difficult to control the installation gap of the big and small molds, and there is often a large gap The problem is that the precision is insufficient, the stability is poor, and the matching structure is easy to wear, loosen or even fail, resulting in the problem of mold collision damage
