Abstract
The utility model relates to a concave-convex type water-cooling forming mould head for a plastic extrusion mould. The mould head is arranged on the exit of the forming section of the plastic extrusion forming mould and the mould head is of a concave-convex shape. The utility model has the advantages of simple operation, easy manufacture, stable technology and easy control, and the product material can be improved nicely. The limit of the widths of the extruded products are broken through, which enables the extrusion forming technologies of the larger width plate materials and the complicated profiled bar to be easy and feasible.
Description
The utility model proposes a kind of lenticular water-cooled shaping die head of plastic extruding forming mould that is used for the plastic extruding forming mould.
Prior art, its structure is shown in Fig. 3,4.The plastic extruding forming mould can export balanced discharging at profiled section in order to reach, normally adopt and directly the die cavity of runner is repaired, regulate resistance by the size that changes die cavity, change the flow velocity of material, perhaps regulate pressure by built-in choker bar, method middle and the right and left material flow realizes in the balanced runner.The difficulty of its operation is very big, also be difficult for stablizing, and it also is confined to extruding the little product of width.In addition, material also has the rollback phenomenon in runner, and this will have a strong impact on the material of products made thereby, and it can't make the line of publishing picture again.
The purpose of this utility model is to overcome the defective of above-mentioned existence, a kind of concavo-convex water-cooled shaping die head that is used for the plastic extruding forming mould is proposed, the flow velocity that makes extruded material evenly, no rollback phenomenon, reach the purpose of balanced discharging, product material after the moulding is improved significantly, and can stablize again and extrude bigger sheet material of width and complicated profile shapes.
Technical solution of the present utility model:
The lenticular water-cooled shaping die head of plastic extruding forming mould is provided in a side of the exit of the profiled section in the plastic extruding forming mould, and it is shaped as concavo-convex;
This concaveconvex shape can be
Shape or ∽ shape or
Shape.
Advantage of the present utility model:
1, processing easy and simple to handle, easy;
2, consistent easy to control, can improve the product material well;
3, big quantum jump to the restriction of extruded product width, make the extrusion technology of bigger sheet material of width and complicated profile shapes simple and easy, feasible.
Accompanying drawing the 1, the 2nd, the utility model are used for the example structure schematic diagram of plastic extruding forming mould.
Accompanying drawing the 3, the 4th, the structural representation of plastic extruding forming mould of the prior art.
Among the figure 1 is shunting section, the 2nd, compression section, the 3rd, profiled section, the 4th, die head, the 5th, choker bar.
Further describe operation principle of the present utility model below in conjunction with accompanying drawing:
The die cavity of plastic extruding forming mould is arranged in the fixed gap scope, extrude needs according to product, mould molding section exit is trimmed to the die head of specific concaveconvex shape, produce different typing segment length, the resistance of the material of different parts is not waited, change the flow velocity of material, thereby realize balanced discharging, stably extrude the purpose of the product of various width.
Claims (2)
1, the lenticular water-cooled shaping die head of plastic extruding forming mould is characterized in that this die head is provided in a side of the exit of the profiled section in the plastic extruding forming mould, and it is shaped as concavo-convex.
2, the lenticular water-cooled shaping die head of plastic extruding forming mould according to claim 1 is characterized in that concaveconvex shape can be
Shape or ∽ shape or
Shape.
