Description

A kind of bar mould

Technical field

It the utility model is related to mould, more particularly to a kind of bar mould.

Background technology

Mould, in industrial production being molded, being blow molded, extruding, die casting or the methods of forging forming, smelting, punching press obtain The various moulds and instrument of required product.In brief, mould is the instrument for formed article, and this instrument is by various parts Form, different moulds is made of different parts, it mainly realizes article by the change of institute's moulding material physical state The processing of shape.

In the extrusion processing of bar, the extrusion diameter of bar is varied from according to the demand of different industries, and factory exists It often can all go to take the mode of more mold exchange to go to achieve the purpose that to produce different product during processing, but so, due to Mould is often all heavier, some volumes are also bigger, therefore cumbersome when replacing, time-consuming and laborious.

Utility model content

In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide a kind of without more Mold exchange can be achieved with being needed to adjust the bar mould of mould extrusion size according to the diameter of extrusion bar.

Technical solution is used by the utility model solves above-mentioned technical problem：A kind of bar mould, including mould bases And the core rod to be connected by discharge nozzle with extrusion equipment, one end that the discharge nozzle is connected with core rod are integrally equipped with connection Set, the core rod are arranged and formed step by step by least 2 grades with upper core, and the core rod by being followed successively by level-one core, diarcs inside outside Core, three-level core etc., one end of cores at different levels offset with connector sleeve inner wall, are opened on the inner wall of the another port of the cores at different levels There is annular groove, and the cores at different levels outer wall of same port in addition to level-one core stretches out to form bulge loop, the cell wall of the annular groove With corresponding screw thread is had on the ring wall of bulge loop, cores at different levels are arranged step by step by annular groove, bulge loop, and described at different levels right Answer the position of annular groove to be equipped with the replacement ring of the replaceable corresponding level core core of level-one inside, the internal diameter of the replacement ring with it is right Answer the internal diameter of rank core consistent.

Further, the rounded funnel-form of the shape of the connector sleeve, and the connector sleeve inner wall corresponds to the position of cores at different levels Put and be integrally convexly equipped with step butt joint ring, so that core at different levels and connector sleeve dock.

Further, screw thread also being provided with the outer wall for replacing ring, the inner surface of the replacement ring is smooth surface, so that It ensure that the smoothness of bar extrusion rear surface.

Compared with prior art, the utility model has the advantage of：The utility model is arranged shape step by step using cores at different levels Into core rod structure replace existing single structure core rod, it is only necessary to by dismantle with regard to can reach bar extrude needs core rod Size, comes compared with more mold exchange, and the utility model operation is more easy and efficient, and the utility model is designed reasonably, meets city Field demand, is adapted to promote.

Embodiment

As shown in Figs 1-4, a kind of bar mould, including mould bases 1 and the mould that is connected by discharge nozzle with extrusion equipment Core 2, one end that the discharge nozzle is connected with core rod 2 are integrally equipped with connector sleeve 3, and the core rod 2 is by least 2 grades with upper core 4 Composition is arranged step by step, and the core rod 2 is at different levels by being followed successively by level-one core 4-1, two level core 4-2, three-level core 4-3 etc. inside outside One end of core 4 offsets with 4 inner wall of connector sleeve, is provided with annular groove 5 on the inner wall of the another port of the cores 4 at different levels, and this is each The level outer wall of same port in addition to level-one core 4-1 of core 4 stretches out to form bulge loop 6, the cell wall and bulge loop 6 of the annular groove 5 Ring wall on have corresponding screw thread, cores 4 at different levels are arranged step by step by annular groove 5, bulge loop 6, and the correspondence at different levels The position of annular groove 5 is equipped with the replacement ring 7 of replaceable corresponding level core 4 core 4 of level-one inside, the internal diameter of the replacement ring 7 It is consistent with the internal diameter of corresponding level core 4, screw thread also is provided with the outer wall for replacing ring 7, the inner surface of the replacement ring 7 is light Sliding surface, so as to ensure that the smoothness of bar extrusion rear surface, the rounded funnel-form of shape of the connector sleeve 3, and the company The position that 3 inner wall of female connector corresponds to cores 4 at different levels is integrally convexly equipped with step butt joint ring 8, so that core at different levels 4 is with being connected The docking of set 3.

The utility model using cores at different levels be arranged step by step the core rod to be formed structure replace existing single structure core rod, Only need, by dismantling the core rod size with regard to bar extrusion needs can be reached, compared with more mold exchange to come, the utility model operates more For simplicity, and it is efficient, the utility model is designed reasonably, accords with the demands of the market, and is adapted to promote.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to It can so modify to the technical solution described in foregoing embodiments, or which part technical characteristic is replaced on an equal basis Change；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technical solution Spirit and scope.
