Abstract

The invention discloses an inverse extrusion type necking mold comprising an ejection device (1), a concave mold sleeve (2), a concave mold (3), a guiding ring (4), a fastening sleeve (5), and a convex mold (6). The mold is characterized in that the ejection device (1) is arranged on the lowermost end of the necking mold. The concave mold sleeve (2) is arranged on the upper end of the ejection device (1). The concave mold (3) is connected on the concave mold sleeve (2). The guiding ring (4) is connected on the upper end of the concave mold (3). The fastening sleeve (5) is arranged on the upper end of the guiding ring (4). The fastening sleeve (5) is connected with the concave mold sleeve (2). The convex mold (6) is also connected on the ejection device (1). The mold has the advantages of good appearance, high production efficiency, and low production cost. With the mold, produced necked valve seats have the advantages of good quality and low rejection rate.

Description

technical field [0001] The invention relates to an inverted extrusion type necking die. Background technique [0002] At present, in the machining industry, the method used to process the necking valve seat is mainly the casting method, that is, using the necking cup-shaped lower mold and the cylindrical upper mold, while pouring the molten metal into the cup-shaped lower mold, using The cylindrical upper mold enters the cup-shaped lower mold, so that the molten metal is hydraulically cast into the valve seat blank. Then, the metal blank is cut to make the required valve seat. Since the casting method needs to be equipped with a melting furnace to smelt the metal, the energy consumption is high and the production cost is high. And because the casting method requires the impurity content of the molten metal to be particularly low, otherwise, air bubbles are likely to appear in the cast valve seat. Therefore, the quality of the valve seat produced by the casting method is p...
