Background technology
Drip irrigation be according to crops to the demand of water, dripped lentamente in soil by low pressure pipeline system and the drip head being arranged on drip irrigation zone, make the soil in crops main root district often keep the irrigation method of optimum water status.Drip irrigation does not destroy the structure of soil, makes soil internal water, fertilizer, air and heat often keep being suitable for the good environment of crop growth, simultaneously, owing to its evaporation loss is little, do not produce surface runoff, almost without deep percolation, be a kind of Water Saving Irrigation Mode being applicable to water-deficient area.
Drip irrigation system is mainly made up of head pivot, drip irrigation zone and drip head three part, and wherein the effect of drip head is to make current form energy loss through small duct, reduces its pressure, instills in soil in the way of drop.Inlaying on the inwall of drip irrigation zone owing to the most conventional SMD drip head need to keep at a certain distance away, the quantity of drip head water inlet is restricted, drip head easily fouling and blocking.For solving this problem, continuous joint strip formula drip head arises at the historic moment.As shown in Figure 1, joint strip formula drip head surface convex portion (dash area in figure) forms, with the inwall of outside pipe racks, the periodicity runner closed continuously, described periodicity runner includes water inlet flow channel section 1-1, turbulent flow flow channel section 1-2 and runner water-retention section 1-3, after a slit outlet is made a call at runner water-retention section 1-3 in matched drip irrigation zone, water just can be oozed by outlet after the energy dissipating through turbulent flow runner.Owing to it can arrange the most hundreds of water inlet, water yield, considerably beyond the needs of normal discharge, in water source during silt blocking portion water inlet, will not be impacted by the quantity of water inlet, and its anti-clogging significantly improves；And the damping action that the design convection cell of its turbulent flow flow channel section 1-2 produces can decay the pressure in runner, makes discharge uniformity be improved.
Above-mentioned continuous joint strip formula drip head can use shaping process of pressure injection to produce, owing to its flow passage structure is complicated, it is high to manufacture precision, and the structural parameters for its periodicity runner of different crops there are differences, and therefore the design to its injection-compression molding mould proposes high requirement.
Summary of the invention
Present invention aims to the manufacture precision requirement of continuous joint strip formula drip head runner, it is provided that the continuous joint strip formula drip head injection-compression molding mould that a kind of simple in construction, low cost of manufacture, universal performance are good.
Problem of the present invention realizes with following technical proposals:
A kind of joint strip formula drip head injection-compression molding mould continuously, it includes rotary disk assembly, inserted ring-type die, pressing plate and rotary shaft, described rotary disk assembly is fixing with rotary shaft to be connected, equipped inserted ring-type die on the external cylindrical surface of rotary disk assembly, it is carved with on described inserted ring-type die and the lines of continuous joint strip formula drip head periodically runner structure matching, described pressing plate is the arc-shaped surface concentric with rotating disk, it is positioned at the outside of rotary disk assembly, and rotary disk assembly, inserted ring-type die and pressing plate form pressure injection die cavity.
Above-mentioned continuous joint strip formula drip head injection-compression molding mould, described rotary disk assembly includes the first rotating disk and the second rotating disk being bolted, described first rotating disk and the second rotating disk junction arrange connected structure, form annular recess in the outside of the first rotating disk and the second rotating disk connected structure, described inserted ring-type die is placed in annular recess.
Above-mentioned continuous joint strip formula drip head injection-compression molding mould, described pressure injection die cavity one end arranges sprue, and the other end arranges discharging opening.
Above-mentioned continuous joint strip formula drip head injection-compression molding mould, the diameter of described first rotating disk and the second rotating disk is not less than 1 meter.
Above-mentioned continuous joint strip formula drip head injection-compression molding mould, described rotary shaft is connected with the drive mechanism of injection-compression molding equipment, rotary shaft rotating speed 1 rpm≤n≤2rpm.
Above-mentioned continuous joint strip formula drip head injection-compression molding mould, described pressing plate centering angle is not less than 150 °.
The present invention is equipped inserted ring-type die in the annular recess of rotary disk assembly external cylindrical surface, pressure injection die cavity is formed by annular recess, inserted ring-type die and pressing plate, after the raw material after heating enters pressure injection die cavity by sprue, compression molding under inserted ring-type die and pressing plate coordinate, and along with the rotation of rotary disk assembly is discharged by discharge outlet.The present invention uses inserted ring-type die, can select different inserted ring-type dies according to the structural parameters of difference continuous joint strip formula drip head periodically runner, improve the universal performance of mould.The present invention the first rotating disk and the second rotating disk diameter are not less than 1 meter, and rotary shaft rotating speed 1 rpm≤n≤2rpm, pressing plate centering angle is not less than 150 °, and above-mentioned technical parameter has fully ensured that molding and the hardening time of continuous joint strip formula drip head.In a word, the present invention has simple in construction, low cost of manufacture, feature that universal performance is good, and it meets the manufacture precision requirement of continuous joint strip formula drip head runner, it is ensured that the product quality of joint strip formula drip head continuously.
