Abstract

The utility model relates to a split type hot extrusion die which is characterized by comprising a master plate, a working band plate and a feed plate, wherein an axial hole is formed at centers of the master plate and the feed plate respectively; a die forming hole is formed at the center of the working band plate; the die forming hole and the axial holes of the master plate and the feed plate are concentric; the die forming hole at the center of the working band plate is smaller than the axial holes of the master plate and the feed plate; the axial holes of the master plate and the feed plate are equal in size; a flat-bottom concave pit is arranged below the feed plate; the lateral size of the flat-bottom concave pit is greater than that of the axial hole of the feed plate; the depth and the shape of the flat-bottom concave pit are respectively the same as the thickness and the shape of the working band plate to ensure that the lower surface of the working band plate is parallel and level to the lower surface of the feed plate after the working band plate is embedded into the flat-bottom concave pit below the feed plate; and the feed plate and the master plate are detachably connected together. By adopting the split type hot extrusion die, the waste can be avoided and the production cost is reduced. The split type hot extrusion die is suitable for extruding aluminium alloy solid profiles.

Description

Split type hot-extrusion mold
Technical field
The utility model relates to a kind of mould.Specifically, be the split type hot-extrusion mold of extruding aluminium alloy solid profile.
Background technology
All know at the hot-extrusion mold production industry, being used for the hot pressurizing mold of extruding aluminium alloy solid profile all is monolithic mold, i.e. master plate, work band plate and feedboard is structure as a whole, can not dismantle.Because the master plate of monolithic mold, work band plate and feedboard is structure as a whole, can not dismantle, the time one is long, when work wearing and tearing can occur with the size of the one-tenth nib at center, so that extruded product is when defective, whole mould can only be scrapped, serious waste phenomenon, and production cost is higher.
Problem to be solved in the utility model provides a kind of split type hot-extrusion mold.Adopt this split type hot-extrusion mold, can avoid waste, reduce production costs.
For addressing the above problem, take following technical scheme:
Split type hot-extrusion mold characteristics of the present utility model are to comprise master plate, work band plate and feedboard, and all there is axial hole at the center of master plate and feedboard, and there is into nib at work band plate center, and this becomes nib concentric with the axial hole of master plate and feedboard.The one-tenth nib at work band plate center is less than the axial hole of master plate and feedboard, and the axial hole equal and opposite in direction of master plate and feedboard.Flat pit is arranged below the feedboard, the lateral dimension of this flat pit is greater than the axial hole of feedboard, the degree of depth of flat pit and shape respectively thickness and the shape with the work band plate are identical, so that the work band plate is embedded into the lower surface of the band plate of working behind the flat pit below the flitch is concordant with the lower surface of feedboard.Being detachable shape between feedboard and master plate links together.
The further improvement of the utility model scheme is, around the master plate and feedboard be evenly equipped with respectively through hole and screw all around, the two is detachable shape by sunk screw and links together.
Further improvement project of the present utility model is, around the work band plate and feedboard around pin-and-hole is all arranged, and the pin-and-hole on the work band plate is corresponding with pin-and-hole on the feedboard, in the band plate of the working a pair of pin-and-hole corresponding with feedboard alignment pin is arranged.
Take such scheme, have the following advantages:
Can be found out by such scheme, because the utility model is combined by master plate, work band plate and feedboard, long when service time one, work wearing and tearing occur with the one-tenth mold hole dimension at center so that extruded product when defective, band plate only need more change jobs, compare with scrapping whole mould in the background technology, not only avoided waste, also reduced production cost.
Description of drawings
Fig. 1 is split type hot-extrusion mold structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, split type hot-extrusion mold of the present utility model comprises master plate 3, work band plate 2 and feedboard 1, the center of master plate 3 and feedboard 1 all is processed with axial hole 6, and work band plate 2 centers are processed with into nib 7, and this becomes nib concentric with the axial hole 6 of master plate 3 and feedboard 1.The one-tenth nib 7 at work band plate 2 centers is less than the axial hole 6 of master plate 3 and feedboard 1, and axial hole 6 equal and opposite in directions of master plate 3 and feedboard 1.Be processed with flat pit below the feedboard 1, the lateral dimension of this flat pit is greater than the axial hole 6 of feedboard 1, the degree of depth of flat pit and shape respectively thickness and the shape with work band plate 2 are identical, so that work band plate 2 is embedded into the lower surface of the band plate 2 of working behind the flat pit below the flitch 1 is concordant with the lower surface of feedboard 1.3 of feedboard 1 and master plates are detachable shape and link together.
Fixing for ease of 1 of master plate 3 and feedboard, around master plate 3 and feedboard 1 be processed with respectively four through holes and four screws all around, be detachable shape by sunk screw 4 between four through holes and four screws and link together.
Location for ease of 1 of work band plate 2 and feedboard, around work band plate 2 and feedboard 1 all be processed with all around pin-and-hole, and the pin-and-hole of work on the band plate 2 is corresponding with pin-and-hole on the feedboard 1, and band plate 2 and the feedboard 1 corresponding a pair of pin-and-hole interpolation of working has alignment pin 5.
