Thermoforming tool with inverted container

Abstract

The invention discloses a hot forming mould of a container with a reversed buckle. The hot forming mould comprises an upper mould body and a lower mould body, wherein the upper mould body and the lower mould body comprise a plurality of mould cavity units for molding the container; the lower mould body is provided with a first ejection plate and a second ejection plate; the first ejection plate is provided with a thimble corresponding to each mould cavity unit; the second ejection plate is provided with an ejection rod corresponding to each mould cavity unit; and the first ejection plate is provided with a through hole for the ejection rod to pass through. According to the hot forming mould disclosed by the invention, a concave pit is prevented from being remained at the bottom of a product in a de-molding process or the upper end face of a turned edge of the outer wall of a product is prevented from being broken by ejection; the product yield is improved, a hot molding machine can be applied to a product with a more complicated shape in a plastic machining process, and the application is expanded; the thickness of a notch part is increased, the strength of the notch is enhanced and the service life of the mould is prolonged; and a driving air cylinder is integrated on the mould bodies so that a rack space and an occupied space are reduced, the utilization of materials is saved and a whole machine structure is simplified.

Description

technical field [0001] The invention relates to a thermoforming mold, in particular to a thermoforming mold which is especially suitable for processing containers with an inverted buckle. Background technique [0002] A variety of plastic products can be seen or used in people's lives, such as cups, saucers, food plates, toys, helmets, as well as auto parts, architectural decorations, chemical equipment, etc. Plastic processing and production include injection molding and thermal Forming, such as cups, saucers, food dishes, toys, helmets, and automotive parts, architectural decorations, chemical equipment, etc. [0003] Existing thermoforming machines for producing plastic containers usually use ejector pins after the mold clamping and punching to push them out of the cavity from the bottom of the container. [0004] However, for products with complex shapes and structures, especially containers with inwardly recessed undercuts or other complex structures such as screw buck...

AI Technical Summary

Problems solved by technology

[0004] However, for products with complex shapes and structures, especially containers with inwardly recessed undercuts or other complex structures such as screw buckles on the outer wall or the edge of the outer wall, it is difficult to complete the demoulding of the finished product with the existing method, even after the demoulding The mold will deform or damage the product

[0005] At the same time, the existing thermoforming molds have simple structures and functions, and their actions need to be controlled by peripheral driving equipment, such as cams, cylinders, hydraulic mechanisms, etc. These driving equipment take up a lot of space, and when the stroke of the cylinder is too long, the forming The machine is huge and occupies a large area, which may even raise the level of the operating table, which is not convenient for manual operation

However, the space in the mold has not been fully utilized, and additional drive equipment has also brought waste of materials
