Abstract
The utility model relates to a processing die for a plastic pipe, and provides a replaceable die core for a reducing pipe. The replaceable die core for the reducing pipe comprises a die core base body; a through bolt hole is formed in the center of the die core base body; and positioning steps are designed at the tail of the die core base body based. The replaceable die core for the reducing pipe is characterized by being divided into two sections, wherein the front section serves as a sizing section, and the rear section serves as a flow guiding plate; and the front section and the rear section are connected with a notch embedding positioning structure through a boss. According to the replaceable die core for the reducing pipe, the front section can be replaced according to the thicknesses of different pipe fittings, the rear section is unchanged, and thus high-quality steel used for manufacturing the die can be saved; and the replaceable die core for the reducing pipe is mainly used for processing plastic pipes with the same aperture and different wall thicknesses.
Description
Technical field
The utility model relates to the plastic pipe processing mold, especially a kind of interchangeable reducer pipe fitting core rod.
Background technology
At present, production polyvinyl chloride-type plastic conduit particularly during bigbore PVC-U pipeline, needs the mould by GB bore, wall thickness dimension requirements making correspondence.For the same caliber, the tubing of different wall also needs to make the core rod of 4-5 kind different size, and in the prior art, core rod is monolithic construction, and this just needs a large amount of high-quality die steels to make the core rod of different size, and manufacturing cost is high, and waste of material is large.
Summary of the invention
The purpose of this utility model will solve exactly existing tubing processing and use monoblock type core rod manufacturing cost high, the problem that waste of material is large, a kind of interchangeable reducer pipe fitting core rod is provided, existing core rod is studied rear discovery, core rod can be divided into two sections of front and back, leading portion is the typing section, back segment is diversion section, for the same caliber, and the tubing of different wall processing core rod, its leading portion diameter dimension changes according to different wall, and the rear section structure size is constant.According to this discovery, the utility model has proposed following solution for the problems referred to above: a kind of interchangeable reducer pipe fitting core rod, have the core rod matrix, and the center of core rod matrix has the bolt hole that runs through, and the afterbody of core rod matrix is designed with positioning step.It is characterized in that: the core rod matrix is divided into two sections formations, and leading portion is the typing section, and back segment is deflector, and the two sections employing boss in front and back are connected with notch setting-in location structure.
Concrete scheme of the present utility model is: a kind of interchangeable reducer pipe fitting core rod according to claim 1, it is characterized in that: the Length Ratio of core rod matrix leading portion and back segment is 2:3.
Concrete scheme of the present utility model is: described a kind of interchangeable reducer pipe fitting core rod according to claim 1, it is characterized in that: the height h of described boss is 6-10mm, the depth H=h+0.5mm of notch.
Use the utility model, for same caliber, the tubing of different wall processing core rod only needs to make a kind of back segment of size, when the leading portion of several sizes, the tubing of production different wall, only needs to change corresponding leading portion core rod and gets final product.Adopt the connecting bolt dress to be integrated leading portion and back segment, cooperate external mold can produce the tubing of corresponding wall thickness.The utility model is simple in structure, and is easy to operate, can save fee of material and processing charges about 65% for one group of core rod.

Fig. 2 is the utility model rear section structure master cutaway view.
Among the figure: 1-leading portion, 2-bolt hole, 3-boss, 4-notch, 5-back segment, 6-positioning step.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model is to consist of the core rod matrix by leading portion 1 and back segment 5 docking, have the bolt hole 2 that runs through in core rod matrix center, and the interface at leading portion is shaped with boss 3, and the interface of back segment is provided with notch 4, and boss 3 height h are made as 6-10mm, be specially 6mm, the depth H of notch 4 is made as 6.5-10.5mm, is specially 6.5mm, and boss 3 is located by connecting with notch 4 setting-ins.
The length L of leading portion described in the present embodiment 1
1=200mm(or 194mm also can), the length L of back segment 5
2=300mm(or 306mm also can).
The afterbody of the present embodiment posterior segment also is designed with positioning step 6.
