As further improvement, above-mentioned core rod is many.As preferably, the diameter difference of the nib of many core rod.The core rod of employing plurality of specifications can be extruded the polytetrafluoroethylsteel steel bar of multiple diameter size in a pushing machine, improved the range of application of pushing machine, and the bar of having avoided producing different size needs the trouble that more mold exchange brought.
As further improvement, between above-mentioned core rod top board and core rod location-plate, be provided with the first cooling water pond, the first cooling water pond is set in the top of positioning convex ring.By being set, the first cooling water pond avoids the heat of bottom to pass to feeder making powder caking make powder when entering core rod, need keep more complete particle, be beneficial to blanking.
As further improvement, be arranged with the second cooling water pond in the outer ring of above-mentioned core rod location-plate.The purpose of the second cooling water pond is to avoid the high temperature of the heating jacket of below upwards to transmit.
As further improvement, above-mentioned pressing device comprises oil cylinder, slide plate chair, sliding sleeve and guide rail, slide plate chair is arranged on the guide rail by sliding sleeve, the upper end of slide plate chair is connected with the piston rod of oil cylinder, the slide plate chair below is provided with location-plate, location-plate is fixed by clamping plate, and described pushing plug is arranged on the location-plate.Above-mentioned structure provides a kind of pushing plug fixed form.
As further improvement, it is excessive that the upper end of above-mentioned nib is provided with circular arc chamfering.Circular arc chamfering helps the powder blanking.
The utility model is owing to adopted above-mentioned technical scheme, when needing more mold exchange, only need take off batching dish and core rod top board earlier, just can advance whole core rod taking-up and change, and do not need whole fuselage is taken off replacing, so just greatly facilitate the replacing of mould.Further, many core rod can adopt the nib of different size, just can carry out the production of different size like this on a loom, and the bar of having avoided producing different size needs the trouble that more mold exchange brought.The utlity model has simple in structure, implement characteristics easily.
