Method for manufacturing plastic vertical water meter cases

Abstract

The invention relates to a manufacturing method of plastic water meter shell, in particular to a manufacturing method of plastic vertical water meter shell. The manufacturing method is characterized in being conducted by the following procedures: firstly, make a plurality of chip embedded lumps and outlet and inlet water core axle jointed into the inner core structure of the water meter and then inserted on the swallow-tail spline shaft; in the following, make the inlet water guide embedded lump and the outlet guide embedded lump connected with one end of the water core axle by a bolt to form integrated core inner module, then make the integrated core inner module installed in the cavity of module, the module is opened after mode locking, injection molding and cool molding by an injection machine; finally, taking out the multiple dissolved core embedded lumps, inlet and outlet water core axle, water inlet guide embedded lumps and water outlet guide embedded block to achieve plastic vertical water meter shell. The manufacture procedure of the manufacture method is simple and easy to practice, which ensures the service life of plastic vertical water meter and solves the difficult technical problem that the one-time injection molding of the plastic vertical water meter can't demould that the technical personnel in the filed are unable to solve for a long time.

Description

technical field [0001] The invention relates to a method for manufacturing a plastic water meter case, in particular to a method for manufacturing a plastic vertical water meter case. Background technique [0002] Existing manufacturing methods for water watch cases are metal water watch cases. For example, Chinese invention patent No. ZL00125206.2 discloses a water watch case and its manufacturing method. In this method, stainless steel sheets are cold-extruded into inner and outer screw caps. , the matching connection port is formed with internal and external threads, and an external thread part is welded with the water pipe connection port, a positioning plate is fixed on the internal surface of the external screw cover, and a counting display hole is opened on the external surface. The invention also provides a manufacturing method for producing the aforementioned watch case. It has the advantages of saving materials, high quality, not easy to leak, and high production ...

AI Technical Summary

Problems solved by technology

The manufacturing method of plastic water meter and the manufacturing method of metal water meter cannot be used universally, because the plastic water meter shell is limited to the plastic manufacturing process, and it is very difficult to demould, especially the shape of the plastic vertical water meter shell is characterized by a large inner cavity, a small mouth, and a concave-convex geometry. There are many surfaces, the water inlet and outlet pipe holes are vertical, and the vertical pipe is divided into two parts from the middle section, forming two sections of the conical diversion channel for the upper water outlet and the lower water inlet. The structure is complex and the product is difficult to demould. It has been a peer research and exploration topic for many years

In order to solve the demoulding problem of the plastic water watch case, those skilled in the art have made considerable efforts, and have made some progress in the demoulding process of the plastic horizontal water watch case, but still cannot find a solution for the injection molding of the plastic vertical water watch case. The problem is that the manufacture of plastic vertical water meter cases has long been in a situation of complicated processes, low work efficiency, and troublesome post-processing of the manufacturing process. Increased service life of plastic vertical water meter case
