Abstract
The utility model relates to an extrusion die with an adjustable gap of a die orifice, which comprises an outer runner outer wall 1 and an outer runner die 2, wherein the outer runner outer wall 1 is matched with the outer runner die 2 through a section of cylindrical surface, and a limiting mechanism and a fastening mechanism are arranged between the outer runner outer wall 1 and the outer runner die 2. When the gap of the die orifice needs to be adjusted, a holding screw 3 on the outer runner die 2 is unscrewed; the outer runner die 2 is rotated so that the axial distance between the outer runner die 2 and a core die 5 is changed. By adopting the extrusion die with the structure, when the gap of the die orifice needs to be adjusted, three die lips do not need to dismantle; melting materials in the runner are eliminated; the adjusting time of the die is greatly shortened; and the production efficiency is improved.
Description
Technical field
The utility model relates to the adjustable extrusion die of a kind of die gap, relates in particular to the extrusion die that a kind of die gap adjustment exempts to dismantle.
Background technology
The online production of bellows extrusion die need be adjusted the die gap size when changing owing to conditions such as material, temperature.The extrusion die die gap is adjusted the structure (see figure 1) at present, mainly is to adopt the adjusting pad 6 of changing different-thickness, changes the axial dimension of outer flow passage inwall, thereby changes the size of die gap.This method need be equipped with corresponding adjusting pad according to different gaps, and the replacing of adjusting pad is very complicated, need disassemble three die lips, removes the fused materials in the runner, wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of extrusion die of exempting to dismantle with regard to adjustable mould preparation mouth gap length is provided.
The technical solution of the utility model is: the adjustable extrusion die of a kind of die gap, comprise outer flow passage outer wall and outflow road junction mould, and cooperate by one section face of cylinder between outer flow passage outer wall and the outflow road junction mould, and be provided with position-limit mechanism and retention mechanism.
Scheme one, the position-limit mechanism of extrusion die are that outer flow passage outer wall and the mould employing of outflow road junction are threaded, and retention mechanism is that outflow road junction mould circumferencial direction is provided with holding screw.
When the die gap size needs to adjust, extrusion die is withdrawed from from make-up machine, jackscrew on the mould of outflow road junction is unscrewed, be hooked on the outer round surface groove of outflow road junction mould with hook-headed wrench again, rotation outflow road junction mould changes the axial distance of outflow road junction mould and core, the variable quantity of determining the gap according to the pitch and the rotating cycle of screw thread, after being transferred to the gap width of wanting, tighten the adjustment that jackscrew is just finished the die gap size.
Another program is, the position-limit mechanism of extrusion die is that the outer flow passage outer wall is provided with step, and the circumferencial direction of step is provided with stop screw; The retention mechanism of extrusion die is that the circumferencial direction of outer flow passage outer wall step is provided with trip bolt.
When the die gap size needs to adjust, extrusion die is withdrawed from from make-up machine, the screw that is connected with outflow road junction mould on the outer flow passage outer wall is unclamped, adjust a mouthful die clearance size then, after reaching the requirement gap, to adjust screw and screw in to put in place and put, and withstand the collar extension mould, and the outer flow passage outer wall and the attachment screw of outflow road junction mould are tightened.Finish the adjustment of die gap size like this.
Use the extrusion die of this kind structure, when needing to adjust die gap, no longer needed to disassemble three die lips, removed the fused materials in the runner, shortened the adjustment time greatly, improved production efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The adjustable extrusion die of a kind of die gap comprises outer flow passage outer wall 1 and outflow road junction mould 2, it is characterized in that: cooperate by one section face of cylinder between outer flow passage outer wall 1 and the outflow road junction mould 2, and be provided with position-limit mechanism and retention mechanism.
As Fig. 2 and a kind of version that Figure 4 shows that the adjustable extrusion die of the utility model die gap.The position-limit mechanism of extrusion die is that outer flow passage outer wall 1 and outflow road junction mould 2 are by being threaded; Retention mechanism is that outflow road junction mould 2 circumferencial directions are provided with holding screw 3.
When the die gap size needs to adjust, extrusion die is withdrawed from from make-up machine, holding screw 3 on the outflow road junction mould 2 is unscrewed, be hooked on the outer round surface groove of outflow road junction mould 2 with hook-headed wrench 4 again, rotation outflow road junction mould 2 changes the axial distance of outflow road junction mould 2 and core 5, the variable quantity of determining the gap according to the pitch and the rotating cycle of screw thread, after being transferred to the gap width of wanting, tighten the adjustment that holding screw 3 is just finished the die gap size.
Be illustrated in figure 3 as the another kind of version of the adjustable extrusion die of the utility model die gap.
The position-limit mechanism of extrusion die is that outer flow passage outer wall 1 is provided with step, and the circumferencial direction of step is provided with stop screw 8; The retention mechanism of extrusion die is that the circumferencial direction of outer flow passage outer wall 1 step is provided with trip bolt 7.
When the die gap size needs to adjust, extrusion die is withdrawed from from make-up machine, the screw 7 that is connected with outflow road junction mould 2 on the outer flow passage outer wall 1 is unclamped, adjust a mouthful die clearance size then, after reaching the requirement gap, to adjust screw 8 and be screwed into the position, withstand the collar extension mould, and the outer flow passage outer wall 1 and the attachment screw 7 of outflow road junction mould 2 will be tightened.Finish the adjustment of die gap size like this.
As shown in Figure 5 and Figure 6, the variable quantity of die gap can show with following formula table:
δ variable quantity=δ 2-δ 1=(Δ 2-Δ 1) sin (α)
Use the extrusion die of this kind structure, when needing to adjust die gap, no longer needed to disassemble three die lips, removed the fused materials in the runner, shortened the adjustment time of mould greatly, improved production efficiency.
It should be noted that at last: though abovely described the specific embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; can make numerous variations or modification to these specific embodiment; and not deviating from principle of the present utility model and essence, protection domain of the present utility model is defined by the claims.
