Abstract
The utility model discloses a novel upper two-mould base structure of a powder forming machine, comprising an upper outstroke fixed on an upper outstroke piston, an upper inward stroke fixed on an upper inward stroke piston, an upper end cover, an outstroke cylinder and an inward stroke cylinder; an upper mould plate is movably connected with an adjusting thread block arranged on the upper inward stroke piston; an outstroke thread bush for adjusting the lower dead centre of the upper outstroke piston is arranged under the upper outstroke piston; two air inlets are arranged between the outstroke cylinder and the upper outstroke piston; and the vertical movement of the upper outstroke piston can be controlled by the switching of the two air inlets. The outstroke cylinder and the outstroke cylinder of the utility model are of a double-acting cylinder, which can ensure the normal demoulding of the product and lead the product can not have crackle when demoulding.
Description
Technical field
The utility model relates to powder compacting machinery technical field, relates in particular to two mode structures on a kind of novel powder make-up machine.
Background technology
In the powder metallurgy product forming process, with single shaft when rigid die is pressed into many step surfaces, often need on two, bring moulding, existing last two in structure, the cylinder of outwash all is a single-acting cylinder, promptly can only drive the outwash piston moves downward, like this when goods during to bottom knockout, last outwash piston can not reliable dead-centre position fixed thereon, but driven with descending towards piston in last by the knockout press of goods, may cause goods to be taken to the die top together and break away from die, the normally demoulding like this by two upper punches, and when suppressing next time, be pressed once more, cause the damage of mould and equipment; Goods may be trapped in by the frictional force between goods and the die in the die simultaneously, because last outwash does not have the normal demoulding, cause goods to crack.
The utility model content
The utility model provides a kind of demoulding normal at above-mentioned defective, thereby keeps two mode structures on the stable novel powder make-up machine of quality of item.
The technical solution of the utility model is: the utility model comprises the last outwash that is fixed on the outwash piston, dash in the going up in being fixed on the piston, be fixed on the upper end cover on the cope match-plate pattern, outwash cylinder and interior towards cylinder, cope match-plate pattern is connected with and is arranged on interior adjustment threaded block towards piston, last outwash piston bottom is provided with adjusts the outwash thread bush of going up outwash piston bottom dead centre, be provided with two air inlets between outwash cylinder and the last outwash piston, by outwash piston up-down on the switching controls of two air inlets, interior towards cylinder and upward interior towards being provided with two air inlets between the piston, go up interior moving up and down by the switching realization of two air inlets towards piston.
Dash in of the present utility model, the outwash cylinder is designed to double-acting cylinder, and the goods demoulding is normally carried out, and makes goods be difficult for cracking when the demoulding.

The specific embodiment
The utility model comprises the last outwash that is fixed on the outwash piston 6, dash in the going up in being fixed on the piston 5, be fixed on the upper end cover 2 on the cope match-plate pattern 1, outwash cylinder 7 and interior towards cylinder 4, cope match-plate pattern 1 is connected with and is arranged on interior outwash threaded block towards piston 5, last outwash piston 6 bottoms are provided with adjusts the outwash thread bush 8 of going up outwash piston 6 bottom dead centres, be provided with two air inlet B between outwash cylinder 7 and the last outwash piston 6, C, move up and down by outwash piston 6 on the switching controls of two air inlets, interior towards cylinder 4 and upward interior towards being provided with two air inlet A between the piston 5, D goes up interior moving up and down towards piston 6 by the switching realization of two air inlets.
The utility model upper end cover 2, interior qi of chong channel ascending adversely cylinder 4, outwash cylinder 7 are fixed on the cope match-plate pattern 1, can be by switching the knee-action that two air inlet A, D control it in interior qi of chong channel ascending adversely cylinder 4 in going up towards piston 5, last outwash piston 6 outside can be by switching the knee-action that two air inlet B, C control it in the qi of chong channel ascending adversely cylinder 7.
Towards the top dead-centre of piston 5, promptly suppress the some position in adjustment threaded block 3 of the present utility model is used for adjusting, outwash thread bush 8 is used for adjusting the bottom dead centre of outwash piston 6, promptly moves the powder location point.
Course of action of the present utility model is: when 1) beginning to suppress, and air inlet B air inlet,, air pressure promote to be gone up outwash piston 6 and is driven and go up outwash 10 and come downwards to desired location, and the position can be adjusted by the position of adjusting outwash thread bush 8, and is interior motionless towards 9 this moment on; 2) after compacting finished, because be subjected to the suffered press power effect of outwash 10, last outwash piston 6 was pushed back upper dead center position, in going up towards piston 5 at upper dead center position, can adjust section poor between two upper punches this moment by the position of adjustment threaded block 3; 3) demoulding: air inlet A air inlet, in in the promotion towards piston 5 drive dash in going up 9 descending with respect to last outwash piston 6, air inlet will be gone up outwash piston 6 simultaneously and be fixed on upper dead center position at this moment, guarantee that it can in the same descending together towards piston 5 by the knockout press band of goods, dash in last 9 live with goods release go up outwash after, the demoulding of goods top finishes.
Claims (1)
1, two mould bases structures on the novel powder make-up machine, comprise the last outwash that is fixed on the outwash piston, dash in the going up in being fixed on the piston, be fixed on the upper end cover on the cope match-plate pattern, outwash cylinder and interior towards cylinder, cope match-plate pattern is connected with and is arranged on interior adjustment threaded block towards piston, last outwash piston bottom is provided with adjusts the outwash thread bush of going up outwash piston bottom dead centre, it is characterized in that, be provided with two air inlets between outwash cylinder and the last outwash piston, by outwash piston up-down on the switching controls of two air inlets, interior towards cylinder and upward interior towards being provided with two air inlets between the piston, go up interior moving up and down by the switching realization of two air inlets towards piston.
