Description

A kind of dismounting hot-extrusion mold of being convenient to

Technical field

The utility model relates to a kind of mould, is specifically related to a kind of easy-to-mount hot-extrusion mold of producing non-ferrous alloy bars such as aluminium alloy, magnesium alloy and copper alloy or section bar.

Background technology

The mould of non-ferrous alloys such as existing production magnalium mainly is made up of punch and all-in-one-piece die, and it is inconvenient to get material, and when the alloy product of production difformity and size, the replacement cost of solid die is high, and the loading and unloading of die are complicated.

Summary of the invention

The purpose of the utility model proposes a kind of simple in structure to existing weak point in the above-mentioned prior art just; Can produce the product of multiple shape and size through changing operational module, and be easy to the hot-extrusion mold of extrusion modling and non-ferrous alloys such as easy-to-mount aluminium, magnesium.

The dismounting hot-extrusion mold of being convenient to of the utility model comprises punch and two parts of die, and said punch partly comprises through punch retainer and is installed in the extruding punch on the cope match-plate pattern bottom surface; Said die partly comprises the lower bolster that is processed with central through hole; Be fixed on the die fixed block of the hollow cylindrical structure of lower bolster top with mode with lower bolster central through hole coaxial line; Be installed in the annular gasket in the die fixed block open tubular column chamber, the operational module that is provided with the hollow die cavity, recessed module, fovea superior module from the bottom to top successively, be provided with heater around the middle and upper part of die fixed block outer wall; The die fixed block of described hollow cylindrical structure is made up of the left and right two halves die fixed block that snaps together with symmetric mode; Wherein: the lower end of right half die fixed block is columnar structured; On the semicircle step of the lower end that is placed in right half die fixed block of the lower end of a left side half die fixed block, and be fixed together through fixed connecting piece; The height of said annular gasket equates with the semicircle shoulder height of right half die fixed block lower end; Said operational module hollow die cavity is a funnel-shaped structure, the die cavity equal diameters of the diameter of the upper mouth of said funnel-shaped structure and recessed module, and the diameter of lower edge mouth equates with the annular gasket aperture; The aperture of said annular gasket equates with the aperture of lower bolster central through hole; The die cavity equal diameters of said recessed module and fovea superior module.

The utility model is provided with the guide pillar that matches with the dowel hole of cope match-plate pattern periphery setting at the lower bolster periphery.

The diameter a and the operational module external diameter b size relationship of the hollow of operational module described in the utility model die cavity lower edge mouth are: a=(1/20 ~ 1/3) b.

The beneficial effect of the utility model is following:

The utility model compared with prior art has following advantage: the operational module of die can be changed according to the needs of producing, and can produce the aluminium alloy extrusions and the bar of multiple different cross section shape and size; Die is made up of three modules, easy installation and removal, and Extruding die is placed on dismountable two semicircular die fixed blocks, is convenient to dismounting, accurate positioning; Heating can be placed on the step of die fixed block outer rim, and heating means are simply effective.

The specific embodiment

To combine embodiment (accompanying drawing) to further describe below the utility model:

Like Fig. 1, shown in 2, the easy-to-mount hot-extrusion mold of the utility model comprises punch and two parts of die, and said punch partly comprises through punch retainer 2 and is installed in the extruding punch 3 on cope match-plate pattern 1 bottom surface; Said die partly comprises the lower bolster 10 that is processed with central through hole; Be fixed on the die fixed block of the hollow cylindrical structure of lower bolster 10 tops with mode with lower bolster central through hole coaxial line; Be installed in the annular gasket 11 in the die fixed block open tubular column chamber, the operational module 8 that is provided with the hollow die cavity, recessed module 7, fovea superior module 4 from the bottom to top successively, be provided with heater 6 around the middle and upper part of die fixed block outer wall; The die fixed block of described hollow cylindrical structure is made up of the left and right two halves die

fixed block

12,5 that snaps together with symmetric mode; Wherein: the lower end of right half die fixed block 5 is columnar structured; The lower end of a left side half die fixed block 12 is placed on the semicircle step of lower end of right half die fixed block, and is fixed together through fixed connecting piece; The height of said annular gasket 11 equates with the semicircle shoulder height of right half die fixed block lower end; Said operational module 8 hollow die cavitys are funnel-shaped structure, the die cavity equal diameters of the diameter of the upper mouth of said funnel-shaped structure and recessed module 7, and the diameter of lower edge mouth equates with annular gasket 11 apertures; The aperture of said annular gasket 11 equates with the aperture of lower bolster central through hole; The die cavity equal diameters of said recessed module 7 and fovea superior module 4.

The utility model is provided with the guide pillar 9 that matches with the dowel hole 13 of cope match-plate pattern 1 periphery setting at lower bolster 10 peripheries.

As shown in Figure 3, the size relationship of operational module described in the utility model 8 is: a=(1/20 ~ 1/3) b.
