Description
Technical Field
The invention relates to the technical field of water collecting and distributing devices, in particular to a manufacturing method of a plastic water collecting and distributing device.
Background
With the increasing surge in metal prices, plastic products are in absolute advantage in price. The water collecting and collecting device made of plastic instead of metal is a future development trend; due to the advantages of materials, the product is smooth in overall design and is formed by one-time injection molding, so that the product is integrally connected, the pressure resistance is higher, and compared with water collecting and collecting devices made of other materials, the water collecting and collecting device has the incomparable advantages.
The common water collecting and distributing device body is mainly formed by assembling copper, aluminum and stainless steel or metal and plastic in a threaded connection mode, the processing process is complex, the number of connecting parts is large, raw material belts or adhesives need to be wound in the assembling and using processes, the construction and installation are inconvenient, and the working efficiency is low. Meanwhile, some metal water collecting and distributing devices on the market are damaged and lost occasionally due to various reasons, unnecessary waste is caused, and engineering cost is increased. In recent years, plastic water collecting and distributing devices appear in China, but the number of connecting end points is too many, some plastic water collecting and distributing devices adopt hot melting socket and spigot, the whole plastic water collecting and distributing device can be scrapped due to operation problems and cannot be repaired; some water distributors are sealed by O-shaped rings, and water leakage is easy to occur due to the fact that the water distributors are in high-temperature environments (serious in thermal expansion and cold contraction) for a long time.
The water collecting and collecting device made of metal materials is heavy and easy to rust and oxidize.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a manufacturing method of a plastic water collecting and distributing device aiming at the defects of the prior art.
In order to achieve the purpose, the invention provides the following technical scheme:
a method for manufacturing a plastic water collecting and distributing device comprises a plastic water collecting and distributing device body (main bar) and a copper pipe joint (embedded joint fittings),
the manufacturing method comprises the following steps:
a. heating, forging and forming the copper bar raw material, turning an outer circle, drilling, turning threads and chamfering edges by a lathe, and then processing into a pipe joint;
b. manufacturing a plugging mandrel, wherein the plugging mandrel is a cylindrical rod made of steel, and a pull ring is arranged on one side end face of the plugging mandrel; the outer diameter of the plugging core shaft is 0.5mm-1mm smaller than the inner diameter of the pipe joint;
c. wrapping the plugging core shaft by adopting a plastic film with high temperature resistance and poor adhesion, and inserting the plastic film wrapped plugging core shaft into the middle through hole of the pipe joint;
d. placing the pipe joint in an injection molding tool of a water distributor in an injection molding machine, and placing the pipe joint at a corresponding interface position;
e. pouring the plastic raw material into a material storage part (blanking) of an injection molding machine, and operating the injection molding machine to inject the plastic melt into an injection mold;
f. the injection molding machine integrates the plastic water collecting and distributing device body and the copper pipe joint fitting in an injection molding mode;
g. after the water collecting and collecting device is integrally formed, cooling and demolding;
h. after demoulding, cooling the water collecting and distributing device to normal temperature, pulling out the plugging core shaft from the through hole of the pipe joint, and tearing off the plastic film.
Through adopting above-mentioned technical scheme, the water collector and collector accessible injection molding machine automatic molding of this application, the preparation technology is comparatively simple for the metal, and can realize automaticly to reduce unnecessary cost of labor, and plastics recoverable and secondary benefit, energy-concerving and environment-protective.
