Abstract
The utility model relates to a co-extrusion machine head internal mold, and belongs to the manufacture apparatus filed of plastic flexible pipes. The internal mold is divided into an internal mold sleeve and an internal mold core, a row of slotted holes with same distance are arranged on a rear flow passage corresponding to a machine head in the internal mold, the internal mold core is installed in the internal mold sleeve, the gap between the internal mold sleeve and the internal mold core is used as a flow passage, and the internal mold sleeve and the internal mold core are fixed together depending on an inner hexangular screw. The co-extrusion machine head internal mold has simple structure, solves the problem that existing internal molds can not plastic-coat flexible pipes whose inner and outer glue layers use different materials, enlarges the application range of plastic-coated flexible pipes, also prolongs the service life of flexible pipes, and saves resource.
Description
Technical field
The utility model relates to the process units field of plastic flexible pipe, specifically a kind of co-extruding machine head internal mold.
Background technology
As everyone knows: at present; the employed head internal mold of general factory all is fairly simple basically; to go out inside and outside glue-line all be the flexible pipe of commaterial to this head internal mold to be used for plastic-coated only, and but being not available to plastic-coated, to produce inside and outside glue-line be the flexible pipe of different materials.Cause so not only that plastic-coated hose suitable environment, anti-day back are aging, resistance to water, oil resistivity and be restricted service life, and wasted resource.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of co-extruding machine head internal mold is provided, and this device can be used for plastic-coated and produce the flexible pipe that inside and outside glue-line uses different materials.
The utility model adopts following technical solution: a kind of co-extruding machine head internal mold, be provided with internal mold, die sleeve and inner mould core in internal mold is divided into, the runner place is provided with the equally spaced slotted eye of a row behind the corresponding head of interior die sleeve, in the interior die sleeve inner mould core is installed, leave the gap as runner between interior die sleeve and the inner mould core, interior die sleeve and inner mould core rely on hexagon socket head cap screw to be fixed together.
The beneficial effects of the utility model are simple in structure, and it has solved existing internal mold can not go out the flexible pipe difficult problem that inside and outside glue-line uses different materials by plastic-coated, has enlarged the scope of application of plastic-coated hose, has also improved its service life, has saved resource.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. inner mould cores among the figure, 2. interior die sleeve, 3. hexagon socket head cap screw, 4. slotted eye.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1, die sleeve 2 and inner mould core 1 in internal mold is divided into, the runner place is provided with the equally spaced slotted eye 4 of a row behind interior die sleeve 2 corresponding heads, and the corresponding position of mmi machine head runner does not have, interior die sleeve is equipped with inner mould core 1 for 2 li, leave certain clearance as runner between interior die sleeve 2 and the inner mould core 1, interior die sleeve 2 and inner mould core 1 rely on hexagon socket head cap screw 3 to be fixed together.
