Abstract

The utility model discloses dies for producing PVC slot pipe, comprising an upper die, a middle die and a lower die which are fixedly connected together. The bottom of the lower die is provided with a feed inlet, and corresponding holes are respectively arranged in the lower die, the middle die and the upper die; the holes are communicated with the feed inlet, and forming die holes are formed. The dies for producing PVC slot pipe is characterized in that the forming die holes are provided with three or more than three; In the same production condition, the dies for producing PVC slot pipe can further raise the output of products in relation to the dies of the forming die holes of one or two products, and thus resource can be saved to a certain extent, energy consumption can be decreased, and production cost can be reduced; The dies for producing PVC slot pipe can be widely applicable to the production of the PVC slot pipes used for installing electric wires.

Description

A kind of mould of producing the PVC barrel

Technical field

The utility model relates to a kind of mould, particularly a kind of mould of producing pvc pipe by hot-extrusion method.

Background technology

In the technology of the PVC barrel that utilizes the hot-extrusion method production application in electric wire is installed, at first raw material is heated into molten condition, utilize pressurized equipment to make the mould of raw material by different size under the molten condition then, thereby make the PVC barrel of all size.Currently used mould comprises the counterdie that is fixedly connected, middle mould and patrix, bottom at counterdie is provided with material inlet, in counterdie, middle mould and patrix, be provided with formed product nib corresponding and that communicate with material inlet, the quantity of formed product nib is two, in the formed product nib forming module is installed.When adopting this mould to produce, under certain working condition,, improved production cost because the restriction of formed product number of orifices can't further improve the output of product, thereby cause the waste of resource to a certain extent.

Summary of the invention

The purpose of this utility model is exactly will provide a kind of under equal conditions can further improve the output of PVC barrel, the mould that reduces production costs.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of mould of producing the PVC barrel, comprise the patrix that is fixedly connected, middle mould and counterdie, the bottom of counterdie is provided with charging aperture, be respectively arranged with corresponding hole in described counterdie, middle mould and the patrix, hole and feeding inlet, be formed into the pattern hole, it is characterized in that described moulding nib is more than three or three.

As the utility model preferred embodiment, describedly be arranged on down, in, the moulding nib in the patrix is four.

The beneficial effects of the utility model are: the mould of production PVC barrel of the present utility model, at counterdie, evenly be provided with more than three or three corresponding in middle mould and the patrix, and with the moulding nib of feeding inlet, thereby under equal working condition, with respect to mould with one or two formed product nib, the utility model can further improve the output of product, thereby can save resource to a certain extent, reduce production costs: particularly when the shaping mould hole number is four, under equal conditions, can improve 1/2nd to 2/3rds output, thereby reduce production cost significantly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a perspective exploded view of the present utility model;

Fig. 2 is the assembling schematic diagram of Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of mould of producing the PVC barrel of the present utility model, comprise patrix 3, middle mould 2 and counterdie 1, counterdie 1, middle mould 2 and patrix 3 are fixedly connected successively by bolt 5, be provided with charging aperture 10 in the bottom of counterdie 1, be respectively arranged with

hole

41,42,43 in counterdie 1, middle mould 2 and the patrix 3, the

hole

41,42,43 that is arranged in counterdie 1, middle mould 2 and the patrix 3 is corresponding mutually, and communicate with the charging aperture 10 of counterdie 1 bottom, thereby be formed into the pattern hole, in the embodiment shown in the figure, the moulding nib has four.

With reference to Fig. 2, in the hole 43 of patrix 3, forming module is installed, forming module comprises and one is spindle core rod 6, is installed in the outer and cylindrical large shaft sleeve 7 that matches with the formed product nib of spindle core rod 6, is installed in the calibration sleeve 8 in the large shaft sleeve 7 and spindle core rod 6, large shaft sleeve 7 and calibration sleeve 8 can be fixed on gland 9 in the formed product nib, one end of spindle oblique crank Z 6 has a cylinder, and constituting one between spindle core rod 6 and large shaft sleeve 7 and the calibration sleeve 8 can be for fused raw material by the slit with formation PVC barrel product.

Like this, the utility model with respect to the mould with one or two moulding nib, can further improve the output of product under equal working condition, thereby can save resource to a certain extent, cuts down the consumption of energy, and reduces production costs.

Certainly, the shaping mould hole number that the utility model adopted also can be set to more than three or four according to actual conditions, and when three or four being set when above, the technique effect that it reached is identical.

Claims
