Abstract

The invention discloses a one-off forming mold of a double-layer rubber tube. The forming mold comprises a first mold core, a second mold core and a mold sleeve. The first mold core sleeves the second mold core. The second mold core sleeves the mold sleeve. The first mold core comprises a round bulge, a ring sleeve, a first mold core body, a cone-shaped connecting part and a second mold core body. The round bulge is located in the middle of the ring sleeve. One end of the first mold core body is connected to the round bulge, and the other end of the first mold core body is connected to one end of the cone-shaped connecting part. The second mold core body is connected to the other end of the cone-shaped connecting part. The second mold core comprises thread, an annular bulge, a cone-shaped outlet, round holes, a through hole and grooves, wherein the thread is close to the first mold core, the annular bulge is located below the thread, the cone-shaped outlet is formed below the annular bulge, the round holes are irregularly formed in the annular bulge, and the through hole is formed in the cone-shaped outlet. The one-off forming mold increases the forming speed, reduces the cost and increases the production efficiency.

Description

The disposal molding mould of double tube
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of disposal molding mould of double tube.
Background technology
Mould be in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts, and it realizes the processing of article profile mainly through the change of institute's moulding material physical state.
The manufacture of existing double tube all adopts two large extruders and two molds, first adopts an extruder and mold to make the sebific duct of the inside, and then at outer bread one deck sebific duct of sebific duct, such shaping speed is slow, and cost is high, and production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of disposal molding mould of double tube, and it improves shaping speed, reduces costs.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of disposal molding mould of double tube, it is characterized in that, it comprises the first core rod, second core rod, die sleeve, first core rod is enclosed within the second core rod, second core rod is enclosed within die sleeve, first core rod comprises boss to be risen, ring set, first core rod body, cone connection, second core rod body, boss works the centre being positioned at ring set, one end of first core rod body is risen with boss and is connected, one end of cone connection is connected with the other end of the first core rod body, second core rod body is connected with the other end of cone connection, second core rod comprises screw thread, annular protrusion, conical outlet, circular hole, through hole, groove, screw thread is near the first core rod, and annular protrusion is positioned at the below of screw thread, and conical outlet is positioned at the below of annular protrusion, circular hole is arranged on annular protrusion brokenly, and through hole is positioned on conical outlet.
Preferably, described second core rod has the first screw hole, and die sleeve has the second screw hole, and the first screw hole is corresponding with the second screw hole.
Preferably, described boss rises and be connected with three reinforcements between ring set.
Preferably, described die sleeve has a sprue and a conical socket, and conical outlet is positioned at conical socket.
Positive progressive effect of the present invention is: the disposal molding mould of double tube of the present invention improves shaping speed, reduces costs, enhances productivity.
