The mould core can be replaced under the condition that the mould core connecting piece and the mould core main body are not required to be replaced, so that the cost is saved, the replacement time is reduced, the defect that the existing mould core is complex to replace is overcome, and the use flexibility of the mould core is improved.
Description
Technical Field
The utility model relates to an extrusion tooling field, concretely relates to PPR extrudes convenience mandrel.
Background
The PP-R (polypropylene random) pipe, also known as a polypropylene pipe of three types, a polypropylene pipe of random copolymerization or a PPR pipe, has the advantages of energy conservation, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scaling, simple and convenient construction and maintenance, long service life and the like, and is widely applied to the building industry, municipal administration, industry and agriculture fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid delivery, agricultural irrigation and the like. The PP-R pipe is made of random copolymerization polypropylene through extrusion and injection molding.
The existing PPR extrusion core mold is of a whole-root design structure, and the whole root needs to be replaced when the PPR extrusion core mold needs to be replaced actually, so that the PPR extrusion core mold is not environment-friendly and takes time.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model aims to provide a PPR extrudes convenience mandrel convenient to change.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
the utility model provides a PPR extrudes convenience mandrel which characterized in that, includes that the mold core is changed a mold core main part, mold core connecting piece through the mold core that the bolt connects gradually.
In a preferred embodiment of the present invention, a first positioning column is disposed at one end of the mold core changing piece connected to the mold core main body, a second positioning column is disposed at one end of the mold core connecting piece connected to the mold core main body, a positioning hole is disposed in the mold core main body, and the first positioning column and the second positioning column are respectively inserted into two ends of the positioning hole; first through holes are formed in the mold core replacing part and the first positioning column, threaded holes are formed in the mold core connecting part and the second positioning column, and the bolts sequentially penetrate through the first through holes and the positioning holes and are screwed into the threaded holes.
The beneficial effects of the utility model reside in that:
this utility model discloses an improve the mold core structure, use the subassembly of four separations to replace original mold core wholly. The mould core can be replaced under the condition that the mould core connecting piece and the mould core main body are not required to be replaced, so that the cost is saved, the replacement time is reduced, the defect that the existing mould core is complex to replace is overcome, and the use flexibility of the mould core is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The PPR extrusion convenience core mold 100 shown in fig. 1 includes a core connecting member 110, a core main body 120 and a core exchanging member 130 which are connected in sequence,
a positioning column 131 is arranged at one end of the mold core replacing part 130 connected with the mold core main body 120, a positioning column 111 is arranged at one end of the mold core connecting part 110 connected with the mold core main body 120, a positioning hole 121 is arranged in the mold core main body 120, and the positioning column 131 and the positioning column 111 are respectively inserted into two ends 121a and 121b of the positioning hole 121.
A through hole 130a is provided in the core exchanging piece 130 and the positioning post 131, a screw hole 110a is provided in the core attaching piece 110 and the positioning post 111, and an M8 type bolt 140 is screwed into the screw hole 110a through the through hole 130a and the positioning hole 121 in this order.
The head 141 of the M8 bolt 140 is pressed against the top of the through hole 130a, the shank 142 passes through the hole 121, and the leg 143 is screwed into the threaded hole 110 a.
The core connector 110, the core body 120 and the core replacement part 130 are firmly connected by coaxial restraining forces.
The M8 bolt 140 extends completely through the core connector 110, the core body 120 and the core change 130.
Owing to possess above-mentioned structure, the utility model discloses a theory of operation lies in:
when the machine is started, the core die 100 is found to be damaged, the core die connecting piece 110 and the core die main body 120 do not need to be disassembled, and the core die 100 can be directly replaced by taking out the M8 type bolt 140 by using the inner hexagonal wrench handle (the core die replacing piece 130 is directly replaced, so that the whole process is simple and convenient, and the core die 100 can be directly screwed back by using the M8 type bolt 140 after being installed.
The utility model has the advantages that:
the mold core changing piece 130 can be directly changed by unscrewing the M8 type bolt 140 for each change without detaching the mold core connecting piece 110 and the mold core main body 120. The complexity is reduced, the service life is prolonged, and the core mold 100 is more convenient and reasonable to replace.
It will be evident to those skilled in the art that the present invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
