Abstract
The utility model discloses a compressed air forming die of the smoothness of the goods inner wall after the shaping can be ensured, the die is included, the die is installed on the die holder, and the die cavity of slotted form is opened on the upper portion of die, still opens vertical lower gas pocket on the die, the convex hot plate directly over the die cavity that lies in the die still, and it has vertical last gas pocket to open on the convex hot plate, and the lower part of convex hot plate is the boss rather than an organic whole, the overall dimension of boss and the die cavity inner wall size of die are unanimous, and the periphery that the lower part of convex hot plate lies in the boss can be dismantled and be connected with the installation piece, the lower terminal surface of installation piece and the lower terminal surface parallel and level of boss, and the lateral surface laminating of installing medial surface with the boss of piece.
Description
Technical field
The utility model relates to Tool and Die Technology, is specifically related to a kind of compressed air mould.
Background technology
Compressed air mould is the one of mould, its have molding cycle short, shaping after goods precision advantages of higher.Existing compressed air mould mainly comprises die and is positioned at heating plate above die, die has with heating plate on all have the passage of some quantity, for passing into and discharging compressed air.The forming principle of above-mentioned compressed air mould is: first from the passage of die, pass into minute-pressure air, sheet material to be formed is made to be adjacent to the lower surface of heating plate, heater plate, be heated to after plasticization temperature until sheet material, stop passing into air, pass into air downwards by the passage on heating plate, make sheet material fall to the die cavity of die, shaping in the die cavity of die after cooling.The weak point that existing compressed air mould exists is: the goods inwall after shaping is often more coarse, and smoothness is poor.
Utility model content
The utility model be intended to provide a kind of guarantee shaping after the compressed air mould of smoothness of goods inwall.
Compressed air mould in this programme, comprise die, described die is arranged on die holder, the top of die has the die cavity of channel-shaped, die also has vertical air holes, also comprise the convex heating plate directly over the die cavity being positioned at die, convex heating plate has vertical upper pore, the bottom of convex heating plate is the boss with its one, the appearance and size of described boss and the mould intracavity wall consistent size of die, the periphery that the bottom of convex heating plate is positioned at boss is removably connected with mounting blocks, the lower surface of described mounting blocks is concordant with the lower surface of boss, and the lateral surface of the medial surface of mounting blocks and boss is fitted.
The beneficial effects of the utility model: when sheet material is heated up, mounting blocks is arranged on the bottom of convex heating plate, sheet material is jointly made to heat up, after upper pore passes into minute-pressure air, the sheet material plastified is made to fall in the die cavity of die by minute-pressure air, at this moment mounting blocks can be unloaded, due to the appearance and size of boss and the mould intracavity wall consistent size of die, therefore convex heating plate moves downward, the inwall of shaping sheet material can be pushed down, until it is shaping, so just can ensure shaping after the smoothness of sheet material inwall, improve plate forming quality.
Further, all have multiple mounting groove in the bottom of boss and mounting blocks, in mounting groove, be provided with heat conduction bar.Boss and mounting blocks set up heat conduction bar, accelerates the intensification of convex heating plate and mounting blocks, be conducive to making sheet material enter plastifying state fast.
Further, the bottom of upper pore is the reaming outwards expanded.Reaming form is made in upper pore bottom, is conducive to passing into of micro pressure gas, increases throughput, provides larger propelling movement power to sheet material.
Further, be also provided with ring set in the periphery of described die, the upper limb of ring set has blade.The blade that ring set is arranged for excise shaping after goods on clout, improve the crudy of goods.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: upper pore 1, convex heating plate 2, mounting blocks 3, die 4, die holder 5, air holes 6, ring set 7, heat conduction bar 8.
Embodiment is substantially as shown in Figure 1: the compressed air mould of the present embodiment, die holder is fixedly installed, die is fixed on die holder, the top of die has the die cavity of channel-shaped, die also has an air holes with the vertical center line of die cavity to this, between two air holes, have a pilot hole, pilot hole passes through for ejector beam, by ejector beam eject shaping after goods.Also be provided with ring set in the periphery of die, the upper limb of ring set has blade.
Convex heating plate is positioned at directly over the die cavity of die, convex heating plate is positioned at its vertical center and has vertical upper pore, and the bottom of upper pore is the reaming outwards expanded.The bottom of convex heating plate is the boss with its one, the appearance and size of boss and the mould intracavity wall consistent size of die, namely the tapering of boss and the internal taper of die cavity consistent.In order to increase firing rate, convex heating plate also can arrange many strip metals heating rod, by heating of metal heating rod, improving the temperature of convex heating plate itself.
The periphery that the bottom of convex heating plate is positioned at boss is removably connected with mounting blocks by bolt, and the lower surface of described mounting blocks is concordant with the lower surface of boss, and the lateral surface of the medial surface of mounting blocks and boss is fitted.Have four mounting grooves in the bottom of boss and mounting blocks, in mounting groove, be provided with heat conduction bar.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
