Abstract

The utility model relates to a novel hollow plastic storing die head, and is characterized in that at least two throw-out collars (1) sleeved with each other are arranged on the die head, wherein, a central throw-out collar (1) is allowed to be connected with at least an oil cylinder (2); other throw-out collars (1) are connected with at least three evenly distributed oil cylinders (2); the upper end of the oil cylinders (2) are fixed on a fixing seat (3); a push rod (4) is allowed to be connected with the lower surface of the central throw-out collar (1); at least three push rods (4) evenly distributed are arranged on the lower surface of other throw-out collars (1); the throw-out collars (1) are connected by the push rods (4) and sleeved with each other, and correspond to a material extruding piston (5) sleeved in a corresponding material storing cylinder (6); and each material storing cylinder (6) is communicated with a corresponding ring-shaped extrusion passage (7) in a mutually sleeved manner. Therefore, multilayer coextrusion and hollow shaping of die heads with different materials are achieved.

Description

A kind of novel plastic hollow molding storing type die head

Technical field:

The utility model relates to a kind of multi-layer co-extruded plastics hollow molding storing type die head.

Background technology:

Traditional plastic hollow moulding storing type die head, owing to have only an accumulator, so, can only carry out the plastic hollow moulding of individual layer.The performance dullness that causes product.

Summary of the invention:

The purpose of this utility model is to provide: a kind ofly can carry out multi-layer co-extruded plastic hollow moulding storing type die head.

The utility model provides: a kind of novel plastic hollow molding storing type die head, it is characterized in that: the throw-out collar of at least two mutual sheathing (1), wherein, except that allowing to connect one above the center throw-out collar (1) with the upper cylinder (2), connect equally distributed at least three oil cylinders (2) above other throw-out collar (1), oil cylinder (2) upper end is fixed on the holder (3); Connect equally distributed at least three push rods (4) below the throw-out collar (1), each throw-out collar (1) connects the corresponding material extrusion piston of mutual sheathing (5) through push rod (4); Material extrusion piston (5) is sleeved in its corresponding accumulator (6), and each accumulator (6) is communicated with separately ring-type by the order of mutual sheathing and extrudes passage (7).If the throw-out collar of at least two mutual sheathing (1) and a plurality of accumulator (6) and the corresponding material extrusion piston of mutual sheathing (5) are multi-layer co-extruded in order to realize; If acentric equally distributed at least three oil cylinders (2), equally distributed at least three push rods (4) are because have only plane of 3 ability stable support.The operation principle of above-mentioned die head is: when die head work begins, material enters separately accumulator (6) from each feed pipe (8), to be parked in material extrusion piston (5) jack-up of accumulator (6) bottom separately, when material extrusion piston (5) when rising to desired location, start oil cylinder (2) work, promote throw-out collar (1), throw-out collar (1) drives push rod (4), push rod (4) drives material extrusion piston (5), be about to material extruding in the accumulator (6) under the material extrusion piston (5), extrude passage (7) layering from ring-type separately and all clamp-on simultaneously in the product mold outside the die head, finish whole work of hollow molding by the postorder operation.

Above-mentioned novel plastic hollow molding die head can improve like this: two feed pipes (8) that connect two mutual sheathing can be arranged in each accumulator (6).Because there are two feed pipes (8) of two mutual sheathing in this accumulator (6), so, during charging two kinds of material can layering, enter in the accumulator (6) simultaneously, just can extrude two layered materials in such accumulator (6).

The invention effect: owing to establish throw-out collar (1) and a plurality of accumulator (6) and the corresponding material extrusion piston of mutual sheathing (5) of at least two mutual sheathing, so, just can realize the multi-layer co-extruded hollow molding of the different materials of die head.

Description of drawings:

Fig. 1, a kind of structural representation of the present utility model.

The specific embodiment:

Embodiment 1, see the throw-out collar (1) of Fig. 1, three mutual sheathing, connect equally distributed three oil cylinders (2) above each throw-out collar (1), each oil cylinder (2) upper end is fixed on the holder (3); Connect equally distributed three push rods (4) below each throw-out collar (1), each throw-out collar (1) connects the corresponding material extrusion piston (5) of mutual sheathing through push rod (4); Material extrusion piston (5) is sleeved in its corresponding accumulator (6), and each accumulator (6) is communicated with separately ring-type by the order of mutual sheathing and extrudes passage (7).Two feed pipes (8) that central authorities' accumulator (6) connect two mutual sheathing like this, the product that three accumulator (6) just can four layers of co-extrusion of coextrusion.

Claims

1, a kind of novel plastic hollow molding storing type die head, it is characterized in that: the throw-out collar of at least two mutual sheathing (1), wherein, except that allowing to connect one above the center throw-out collar (1) with the upper cylinder (2), connect equally distributed at least three oil cylinders (2) above other throw-out collar (1), oil cylinder (2) upper end is fixed on the holder (3); Connect equally distributed at least three push rods (4) below the throw-out collar (1), each throw-out collar (1) connects the corresponding material extrusion piston (5) of mutual sheathing through push rod (4); Material extrusion piston (5) is sleeved in its corresponding accumulator (6), and each accumulator (6) is communicated with separately ring-type by the order of mutual sheathing and extrudes passage (7).

2, novel plastic hollow molding die head according to claim 1 is characterized in that: a feed pipe (8) that connects two mutual sheathing can be arranged in each accumulator (6).
