Description

Die-casting punch for smelting electrode blocks of titanium and titanium alloy Technical Field The application relates to the technical field of die casting of titanium and titanium alloy smelting electrode blocks, in particular to a die casting punch of a titanium and titanium alloy smelting electrode block. Background Compared with other conventional metals, titanium has the advantages of better high strength, corrosion resistance and the like, and is prepared into titanium and titanium alloy products by single raw materials or mixing with other metals, so that the titanium has wide application in the fields of aerospace, chemical industry, medical treatment, ocean engineering and the like. At present, titanium and titanium alloy products are mainly prepared by mechanically casting sponge titanium or a mixture of sponge titanium and other metal raw materials into a block-shaped structure, then smelting the sponge titanium or the mixture of sponge titanium and other metal raw materials into an ingot in a vacuum smelting furnace as an electrode block, and then processing the ingot into available product forms such as bars, wires, pipes and the like through various mechanical processing modes. According to the method, sponge titanium or other raw materials are mixed and then pressed through a die casting machine as shown in the accompanying drawings 1-2 of the specification, the raw materials are quantitatively filled into a die casting groove body in a specific pressing operation as shown in the figure 2, a die casting punch is driven to enter the die casting groove body through hydraulic acting force to extrude the bulk raw materials into a block-shaped structure, and then a plurality of block-shaped die casting blocks are welded (the height of the whole electrode block can be increased after welding so as to adapt to the height of a crucible in a smelting furnace, the single smelting amount is increased, and the energy consumption is reduced) and placed in the smelting furnace to be used as the electrode block to be smelted into cast ingots. At present, when the die casting of single electrode block is carried out, as shown in fig. 4, because there is the embedding clearance between die casting drift and the die casting cell body inner wall, lead to after die casting shaping, the raw materials of electrode block side department can be extruded and filled into this embedding clearance, and then after die casting shaping, form die casting deckle edge in electrode block's side department, as shown in fig. 5, when carrying out the welding operation of adjacent electrode block, this die casting deckle edge makes adjacent electrode block can not contact mutually, can not carry out stable welding, when welding is accomplished and is hoisted it in the crucible, also there is the risk of droing, and can not carry out stable electrode conduction when being regarded as the electrode in the smelting process, therefore at present after single electrode block die casting shaping, need the staff to strike the die casting deckle edge, make it be less than the die casting face and not influence the welding, this manual operation increases the shaping process of electrode block, simultaneously the die casting deckle edge still has the metal strength, there is great physical burden when the artifical long-time continuous strike, increase production cost. Disclosure of utility model Aiming at the problems, the application aims to provide a die-casting punch for smelting an electrode block by titanium and titanium alloy, which can enable die-casting burrs in the die-casting process of the electrode block to be lower than the surface of the electrode block, does not cause blocking influence on welding after the adjacent electrode blocks are attached, improves the welding tightness of the electrode block, solves the current working procedures of subsequent manual knocking operation again, improves the production efficiency and reduces the cost. In order to achieve the purpose, the technical scheme includes that a die-casting punch head of a titanium and titanium alloy smelting electrode block is matched with a die-casting punch head, a die-casting groove body with an opening at the top is formed in the die-casting groove body, and die-casting raw materials are contained in the die-casting groove body. Further, the die-casting structure is a groove formed in the bottom surface of the die-casting punch, the bottom surface of the groove is a die-casting surface, and a die-casting side edge is formed between the groove and the side edge of the die-casting punch. Preferably, a die-casting plate is detachably arranged on a die-casting side edge of the bottom surface of the die-casting punch, a die-casting ring plate contacting with the side edge of the die-casting electrode block is annularly extended downwards on the side edge of the die-casting plate, and the side edge of the electrode block is positioned at the middle position of
