Vertical demoulding mechanism for large-specification corrugated pipe fittings

Abstract

The invention discloses a vertical demoulding mechanism for large-specification corrugated pipe fittings. The vertical demoulding mechanism comprises an upper template and a lower template of a die; a fixed template is connected below the upper template; a fixed die insert is arranged in the fixed template; a die core insert is arranged on the lower template; die cavity inserts are respectively arranged on four sides of the die core insert; die cavities are formed between the die cavity inserts and the die core insert and between the die cavity inserts and the fixed die insert; and the formed corrugated pipe fittings are arranged in the die cavities. The vertical demoulding mechanism is characterized in that: oblique slip cylinders are respectively arranged on the outer walls of the die cavity inserts; a piston rod of each oblique slip cylinder is connected with the fixed template; oblique guide holes are respectively formed in the die cavity inserts; an oblique guide rod is arranged in each oblique guide hole; each oblique guide rod is connected with the fixed template; push plates are arranged between the die cavity inserts and the lower template and outside the die core insert; the inside ends of the push plates are in contact with the bottoms of the corrugated pipe fittings; push cylinders are arranged on the outer walls of the push plates; and piston rods of the push cylinders are connected with the lower template.

Description

technical field [0001] The invention relates to a vertical demoulding mechanism for large-scale corrugated pipe parts, which belongs to the field of plastic moulds. Background technique [0002] At present, in pipeline connection, corrugated pipe fittings are often used. The production of corrugated pipe fittings in the prior art generally adopts horizontal processing, that is, after the corrugated pipe fittings are formed, they are placed horizontally. The main structure of the processing mold includes an upper cavity and a lower cavity, and there is a core between the upper and lower cavities. At this time, the power of the injection molding machine drives the lower cavity to separate from the upper cavity (mold opening), and the core and the formed bellows run along with the lower cavity. After the upper and lower cavities are separated, the oil cylinder drives the core to pull the core. After the core is pulled out, the ejector pin in the mold is driven by the ejector m...

AI Technical Summary

Problems solved by technology

However, when producing large-scale corrugated pipe parts, due to the large size of the corrugated pipe parts, the horizontal placement of the corrugated pipe parts results in a large mold volume, and it is necessary to use a large-scale injection molding machine to produce, resulting in a large cost investment
