Problems solved by technology

If one of the molds is replaced, the entire core fixing plate needs to be disassembled, which is time-consuming and laborious. The whole process takes 1 to 2 days, which affects production efficiency
The core ejector parts of all molds are installed on the core template, which has high requirements on the gravity of the core template, so the core template is often made very thick, and the core workpiece of the mold itself is long, generally larger than 300mm, the processing accuracy is very high, the mold wears out quickly during the working process, the mold maintenance cost is high and the life span is short

Abstract

The invention belongs to the field of bottle cap injection molding and particularly relates to a modular bottle cap mold. The modular bottle cap mold comprises movable mold sets and fixed mold sets. The movable mold sets and the fixed mold sets are installed on a mold core fixing plate and a mold cavity fixing plate respectively. The fixed mold sets comprise mold cavities. Sprue bushings and mold cavity inserts are arranged in the mold cavities. The movable mold sets comprise mold cores and ejection rods. The tops of the ejection rods are in contact with first ejection plates. Sliding-block mold-opening push rings are arranged in the first ejection plates. Three or more sliding blocks are arranged on the sliding-block mold-opening push rings in each first ejection plate. Sliding-block fixing plates and sliding-block opening and closing driving rods are arranged on the outer sides of the sliding blocks. The modular bottle cap mold is of a multi-sliding-block structure, so that a breaking point is stressed from all sides during mold opening; thus, hand power for a pull ring is uniform, the breaking point joint is also uniform, and cap opening force is uniform. The mold is very compact, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of bottle cap injection molding, in particular to a modular bottle cap mould. Background technique [0002] The traditional multi-cavity bottle cap mold slider is mostly HALF slider type, because the bottle cap tearing ring (such as figure 1 , as shown at E), the breakpoint must be designed according to the direction of the slider mold opening, so the traditional HALF slider mold will cause inconsistent connection lengths of the breakpoints of the tear rings, and the connection part at the contact point of the two HALF block tear rings is relatively large, Such as figure 2 , The length of the breakpoint connection is uneven, which makes it more difficult for the user to open the cover, and the opening experience is poor. [0003] In traditional molds, the core and core ejection parts are usually installed in the core fixing plate, such as Figure 4 As shown, and the connection between the mold and the core fixing ...
