Description

Polyvinyl chloride drain pipe production mould

Technical Field

The utility model relates to a water pipe mould technical field, concretely relates to polyvinyl chloride drain pipe production mould.

Background

At present, various domestic polyvinyl chloride drainage pipes are made by extruding a soft polyvinyl chloride film, adding an extruded hard polyvinyl chloride rib, and reinforcing the excircle of the extruded soft polyvinyl chloride film to form a winding shape.

Although the method can effectively wind and form the product, the hard polyvinyl chloride can deviate in the production process, so that the pitch of the pipe body is uneven, even cracks occur, and the product quality is unstable.

Therefore, how to design a polyvinyl chloride drain pipe production mold is a problem to be solved at present.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a polyvinyl chloride drain pipe production mould for the rib can not produce the skew.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model discloses the first aspect provides a polyvinyl chloride drain pipe production mould, including die head connector, rib die head and film die head, the rib die head is located in the die head connector, the rib die head is strip and inside toper inner chamber that forms, be equipped with the exocoel between die head connector and the rib die head, exocoel and toper inner chamber form the mouth that crosses at rib die head tip intercommunication, still be equipped with rib extruder interface and film die head interface on the die head connector and cross the extrusion die mouth, rib extruder interface switches on with the toper inner chamber, film die head is connected to film die head interface one end, and the other end switches on with the exocoel, cross the extrusion die mouth and cross the mouth and switch on.

Preferably, the die connector comprises two parts, namely a die connecting structure and an extrusion structure, and the die connecting structure and the extrusion structure are fixedly formed through screws.

The above technical scheme of the utility model has following profitable technological effect:

when the die is used for extruding the water pipe, the ribs of the die cannot deviate, the reinforcing effect is good, and the rate of certified products is more than 99%.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1, the utility model provides a polyvinyl chloride drain pipe production mould, including die head connector 1, rib die head 2 and film die head 3, rib die head 2 is located in die head connector 1, rib die head 2 is strip and inside toper inner chamber 4 that forms, be equipped with exocoel 5 between die head connector 1 and the rib die head 2, exocoel 5 and toper inner chamber 4 form the mouth that crosses at rib die head 2 tip intercommunication, still be equipped with rib extruder interface 6 and film die head interface 7 on the die head connector 1 and cross extrusion die mouth 8, rib extruder interface 6 one side switches on with toper inner chamber 4, and the extrusion mouth of rib extruder is connected to the opposite side for the rib that extrudes through the rib extruder can get into in toper inner chamber 4 smoothly, and cross at the mouth that crosses with the film in the inner chamber 5. One end of the film die head interface 7 is connected with the film die head 3, the other end is communicated with the outer cavity 5, and the intersection extrusion die orifice 8 is communicated with the intersection orifice. The ribs and the film do not interfere with each other before entering the intersection port, so that the polyvinyl chloride ribs are prevented from shifting, and are mixed in the intersection extrusion die orifice 8 after passing through the intersection port.

And winding forming equipment is arranged on the outer side of the intersection extrusion die orifice 8, and materials extruded out of the intersection extrusion die orifice 8 can be wound through the winding forming equipment to produce a water outlet pipe.

In one embodiment, the die connector 1 includes two parts, namely a die connecting structure 100 and an extrusion structure 110, and the die connecting structure 100 and the extrusion structure 110 are fixed and formed by screws. Its aim at, can separate die head connection structure 100 and extrusion structure 110 through dismantling the screw, and then will intersect extrusion die mouth 8 and break away from the exocoel 5 and the toper inner chamber 4 and form the mouth that intersects in the intercommunication of rib die head 2 tip, be convenient for clear up the mouth that intersects.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
