Abstract

The utility model discloses an extrusion die head. The extrusion die head comprises a die head body, wherein the die head body is provided with a channel with an inlet and an outlet; n baffling blocks are arranged at the outlet of the die head body; and (n+1) small outlets are formed on the outlet. With the adoption of the extrusion die head disclosed by the utility model, the extrusion efficiency can be improved.

Description

A kind of extrusion die

Technical field

The utility model design extrusion die.

Background technology

In extrusion molding, in order to extrude the cross sectional shape wire rod that needs, then need extrusion die be installed at extruder.Existing extrusion die all has only an outlet, and its efficient of extruding is low, and when thickness that need to adjust wire rod and width, then must change extrusion die in addition, has brought constantly to operation, simultaneously, has also increased cost.

Summary of the invention

The purpose of this utility model provides a kind of extrusion die, utilizes this extrusion die, then can improve extrusion efficiency.

For achieving the above object, a kind of extrusion die comprises the die head body, and the die head body is provided with the passage with import and outlet; Be positioned at the exit at the die head body and be provided with n block, form n+1 little outlet in the exit.

Said structure when material is expressed into outlet, is then shunted under the effect of block, thereby can be extruded n+1 bar wire rod simultaneously, thereby improved extrusion efficiency.

As improvement, be provided with the flange that extends laterally in the exit of die head body; Described block comprises the blocking part, from the two ends, blocking part and the connecting portion vertical with the blocking part and the limiting section that extends to the inside from connecting portion one end, be formed with draw-in groove between blocking part, connecting portion and the limiting section, block by the draw-in groove holding on flange; Be provided with lock-screw in the blocking part.In this structure, flange can be equivalent to slide rail, draw-in groove can be equivalent to chute, after unclamping lock-screw, then can regulate the position of block, after tightening lock-screw, then can fixed stop, and under the effect of blocking part, can realize shunting to material, thereby reach the purpose of regulating little exit width, finally reach the purpose of regulating wire width, like this, according to the demand of producing, then can extrude the wire rod of different in width simultaneously, do not needing to change under the situation of extrusion die and can realize, thereby improving production efficiency, reducing cost.

As improvement, the cross section of passage is square, and four inner side edges of passage dwindle to outlet gradually from import.This structure is convenient to many wire rods of moulding simultaneously, and is conducive to improve the flowable of material, is convenient to moulding.

As improvement, be welded with the reinforcement gusset at the outer wall of die head body, strengthen gusset by design, can improve the intensity of extrusion die.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.

As depicted in figs. 1 and 2, a kind of extrusion die comprises die head body 1.As shown in Figure 4 and Figure 5, die head body 1 has a passage 11, has an import 12 and an outlet 13 on the passage.As shown in Figure 3, the cross section of die head body 1 is square, and the four side of die head body 1 dwindles the formation taper type from import 12 gradually to outlet 13, and four inner side edges of passage also dwindle the formation taper type from import 12 to outlet 13 gradually.Extremely shown in Figure 5 as Fig. 3, in passage 11, be provided with flow distribution plate 2, flow distribution plate near the outlet an end tilt laterally, as material after import 12 enters in the passage, under the effect of flow distribution plate, material can be assigned to outlet uniformly, make that the wire quality of extruding is good.

As shown in Figures 2 and 3, be welded with at the outer wall of die head body and strengthen gusset 3, to improve the intensity of die head body.

, be positioned at outlet 13 places at the die head body and be provided with the flange 14 that extends laterally to shown in Figure 5 as Fig. 1.

Be provided with n block 4 in the exit, will export 13 and be isolated into n+1 little outlet 5, in the present embodiment, the quantity of block is 2, and the quantity of little outlet is 3, then can extrude three wire rods simultaneously.As shown in Figure 2, described block 4 comprises blocking part 41, from the two ends, blocking part and the connecting portion 42 vertical with the blocking part and the limiting section 43 that extends to the inside from connecting portion one end, be formed with draw-in groove 44 between blocking part 41, connecting portion 42 and the limiting section 43, block passes through draw-in groove 44 holdings on flange 14; Be provided with lock-screw 45 in the blocking part.This structure, flange 14 is equivalent to slide rail, draw-in groove is equivalent to chute, when unclamping lock-screw 45, removable block 4 then is to regulate the width of each little outlet, be convenient to the wire rod of one-shot forming place different in width, thereby improved the efficient of extruding, needing also to have avoided many cover extrusion dies could realize obtaining the problem of different in width wire rod, thereby reduced cost.

As Fig. 2, Fig. 4 and shown in Figure 5, in passage, be welded with jointed shaft 6 near an outlet end of 13, be hinged with articulated slab 7 more than two at jointed shaft, be respectively equipped with the adjustment screw 8 more than two in corresponding position with every articulated slab on the die head body 1.By adjusting adjustment screw 8 separately, the openings of sizes that then can regulate articulated slab and outlet, like this, an extrusion molding then can moulding place different-thickness wire rod, and, by regulating adjustment screw, can also close outlet wherein, make that the flexibility of operation is good, and the efficient height of extruding.

As shown in Figure 6, when needs are extruded, then extrusion die of the present utility model is connected on the extruder 9.Then, regulate the position of block and articulated slab, then can once extrude the wire rod of many different in width different-thickness, like this, can not only satisfy the demand of production, and can improve extrusion efficiency, can also reduce cost.
