A continuous strip type drip irrigation head pressure injection molding mold

Abstract

The invention discloses a continuous strip pasting type drop irrigation head injection-compression molding die which is used for realizing injection-compression molding of a continuous strip pasting type drop irrigation head. The continuous strip pasting type drop irrigation head injection-compression molding die comprises a rotating disk component, an embedded type annular female die, a pressing plate and a rotating shaft, wherein the rotating disk component is fixedly connected with the rotating shaft; the embedded type annular female die is arranged on the outer cylindrical surface of the rotating disk component; lines matched with a periodic runner structure of the continuous strip pasting type drop irrigation head are arranged on the embedded type annular female die in an engraving manner; the pressing plate is provided with an arc curved surface concentric with the rotating disk and is positioned on the outer side of the rotating disk component; the rotating disk component, the embedded type annular female die and the pressing plate form an injection-compression die cavity. The continuous strip pasting type drop irrigation head injection-compression molding die has the characteristics of simple structure, low manufacturing cost and high generality; a requirement on the manufacturing precision of a continuous strip pasting type drop irrigation head runner is met, and the quality of a continuous strip pasting type drop irrigation head product is guaranteed.

Description

technical field [0001] The invention relates to a pressure injection molding mold, in particular to a pressure injection molding mold suitable for a continuous strip type drip irrigation head, and belongs to the technical field of plastic molding molds. Background technique [0002] Drip irrigation is an irrigation method that slowly drips water into the soil through a low-pressure piping system and a drip irrigation head installed on a drip irrigation belt according to the water demand of the crops, so that the soil in the main root zone of the crops often maintains an optimal water content condition. Drip irrigation does not destroy the structure of the soil, so that the water, fertilizer, air, and heat inside the soil can always maintain a good environment suitable for the growth of crops. At the same time, because of its small evaporation loss, no ground runoff, and almost no deep leakage, it is a suitable Water-saving irrigation in water-scarce areas. [0003] The drip...

AI Technical Summary

Problems solved by technology

Since the currently commonly used patch-type drip irrigation heads need to be inlaid on the inner wall of the drip irrigation belt at a certain distance, the number of drip irrigation head inlets is limited, and the drip irrigation heads are easily scaled and blocked.
