Abstract

The utility model discloses an improved exhaust pipe fitting insert structure, and relates to the technical field of pipe fitting injection molds. The annular exhaust groove is additionally arranged, so that the gas in the pipe fitting cavity is exhausted after entering the annular exhaust groove from the radial exhaust groove, the gas trapping phenomenon in the pipe fitting cavity is reduced, and the product yield is improved.

Description

Exhaust improvement type pipe fitting mold insert structure

Technical Field

The utility model relates to the technical field of pipe fitting injection molds, in particular to an improved exhaust pipe fitting insert structure.

Background

In the conventional insert structure for the pipe fitting, as shown in fig. 1 and 2, a plurality of radial exhaust grooves 20 are formed in the surface of an insert 10, so that gas trapping phenomenon is easily caused in a pipe fitting cavity in the injection molding process, the gas cannot be timely exhausted to the outside, the defects of the pipe fitting product are caused, and the yield of the product is reduced.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model solves the technical problems of reducing the gas trapping phenomenon in the pipe fitting cavity and improving the product yield.

In order to solve the technical problems, the technical scheme adopted by the utility model is an improved exhaust pipe fitting insert structure which comprises an insert, a plurality of radial exhaust grooves and an annular exhaust groove, wherein the surface of the insert is provided with the radial exhaust grooves, outer ports of the radial exhaust grooves are arranged and communicated with the annular exhaust groove, the annular exhaust groove is provided with an exhaust port, and gas in a pipe fitting cavity is exhausted out of the body through the exhaust groove and the annular exhaust groove.

Preferably, the number of the radial exhaust grooves is 7.

Preferably, the annular exhaust groove is 15 mm away from the periphery of the pipe piece cavity.

Preferably, the annular exhaust groove has a width of 5 mm and a depth of 0.02 mm.

Compared with the prior art, the annular exhaust groove is additionally arranged, so that the gas in the pipe fitting cavity is exhausted after entering the annular exhaust groove from the radial exhaust groove, the gas trapping phenomenon in the pipe fitting cavity is reduced, and the product yield is improved.

Detailed Description

The following description will be made with reference to the accompanying drawings, but the present invention is not limited thereto.

Fig. 1 and 2 show the insert structure of the existing pipe fitting, wherein a plurality of radial exhaust grooves 20 are formed in the surface of an insert 10, so that gas trapped in a pipe fitting cavity is easily generated in the injection molding process, the gas cannot be timely exhausted to the outside, the pipe fitting product defect is caused, and the product yield is reduced.

Fig. 3, fig. 4 show an improvement type pipe fitting mold insert structure of exhausting, including mold insert 1, a plurality of radial exhaust groove 2 and annular exhaust groove 3, the 1 surface of mold insert is provided with a plurality of radial exhaust groove 2, and the outer port setting of a plurality of radial exhaust groove 2 communicates annular exhaust groove 3, and annular exhaust groove 3 is provided with gas vent 31, and the gas in the pipe fitting die cavity is external through exhaust groove 2 and the exhaust of annular exhaust groove 3.

Preferably, the number of radial degassing grooves 2 is 7.

Preferably, the annular vent groove 3 is located 15 mm from the circumference of the tube cavity.

Preferably, the annular vent groove 3 has a width of 5 mm and a depth of 0.02 mm.

When the utility model works, the gas in the pipe fitting cavity is guided into the annular exhaust groove 3 by the plurality of radial exhaust grooves 2 and then is exhausted out of the body by the exhaust port 31.
