Problems solved by technology

[0002] Polyvinyl chloride (PVC) water supply pipe is a kind of synthetic material that is loved, popular and widely used in the world today. Its global usage ranks second among all kinds of synthetic materials. At present, our domestic production The specifications of polyvinyl chloride (PVC) water supply pipe molds are all below 800, and the flow channel design in the mold is not very reasonable during the production process, which affects the supply speed of raw materials, thereby affecting the molding of products, and large-diameter pipes The mold requires many parts to be spliced ​​together. The joints formed by ordinary splicing may be uneven and scraped, so that the mold needs to be cleaned after a period of production, and the molding cavity is relatively long. , it is not easy to adjust the accuracy of its molding cavity

Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] see figure 1 , the present invention provides a technical solution: a polyvinyl chloride PVC water supply pipe mold, including a shell 1 and a mandrel 2, characterized in that: one end of the shell 1 is fixed with a flow channel inlet 3, the flow channel The inlet 3 is fixedly connected with an annular flow channel 4 opened inside the casing 1. The annular flow channel 4 runs through both ends of the casing 1 and divides the casing into an outer casing ...

Abstract

The invention discloses a polyvinyl chloride PVC water supply pipe mold, which comprises a shell, a nut washer and a mandrel. The top and bottom of the housing are respectively provided with torpedo tips, and the inside of the housing is provided with a first mold runner and a second mold runner, the first mold runner and the second mold runner are respectively arc-shaped, and the first mold The runner and the second mold runner are arranged around the mandrel, and the torpedo points are respectively arranged between the first mold runner and the mandrel and between the second mold runner and the mandrel. between the mandrels. The present invention has solved the expansion parts of the mould, all of which are linear runners on the market; the double-layer bracket mold requires high manufacturing precision and is difficult; the die of polyvinyl chloride (PVC) 1200 water supply pipe mold is very long, and the The position of the die installation is adjusted, and it is difficult to adjust the problem of movement.
