Embodiment Construction

[0015] A multi-layer PE water purification pipe mold (hereinafter referred to as the mold), including a rear mold body 10, a transition plate 20, a sinker plate 30, a bracket plate 40 and a mouth template 50 connected in sequence. The specific assembly relationship is as follows: the rear mold body 10 Connected to the extrusion equipment; the transition plate 20 is positioned on the rear mold body 10 with positioning pins, the sinking plate 30 is positioned on the transition plate 20 with positioning pins, and the bracket plate 40 is positioned on the sinking plate 30 with positioning pins. The formwork 50 is fixed on the rear mold body 10 with the support plate 40, the sinker plate 30, and the transition plate 20 with 12.9 grade high-strength hexagon socket bolts. The mold was heated on all sides with cast aluminum heaters.

[0016] The mouth template 50 has a structure such as figure 1 As shown, for accommodating and shaping PE, the mouth template 50 includes a PE groove 51...

Abstract

The invention discloses a multilayer PE water purification pipe mold. The multilayer PE water purification pipe mold comprises a sinking plate, a bracket plate and a mouth template connected in sequence; PE grooves are formed in the mouth template for dividing the mouth template into an inner cavity and an outer cavity; U-shaped through holes are formed in the sinking plate, the bracket plate andthe mouth template; one ends of the U-shaped through holes are formed in the inner cavity; and the other ends of the U-shaped through holes are formed in the outer cavity. The U-shaped through holes are provided for communicating the inner and outer cavities of the mouth template, so that air naturally flows; and in the pressing mold manufacturing process, the air in a gap between the bracket plate and the mouth template is extruded out to prevent liquid-state PE entering the gap to form direct bonding closure of PE pipe ribs and ribs ( channels communicating into the corresponding PE grooves).

Description

technical field [0001] The invention belongs to the field of PE water purification pipes, in particular to a multi-layer PE water purification pipe mold. Background technique [0002] During the production of PE multi-layer water purification pipe, due to the temperature of the mold, the length and structure of the product and its own weight, it is easy to directly bond and seal the ribs and ribs during on-site production, and the extrusion process is a continuous and uninterrupted production process. As long as the product is closed, the PE multi-layer water purification pipe will continue to be scrapped. Contents of the invention [0003] The object of the present invention is to provide a multi-layer PE water purification pipe mold that prevents PE multilayer water purification pipe ribs from sticking and sealing. [0004] In order to achieve the above object, the concrete scheme of the present invention is as follows: [0005] A multi-layer PE water purification pip...
