A multi-movement mold device and its manufacturing method

Abstract

The invention discloses a multi-acting mould device and a manufacturing method thereof. The multi-acting mould device mainly comprises a multi-acting press, a molding device, a fusing jacket device, a vibrating device, an electroslag re-melting furnace, a gouging device, an electrolytic grinding device, an electric spark device and a cutting tool, wherein the multi-acting press comprises a pressing side ejector rod, a pull ring ejector rod, a main anvil head ejector rod, a pressing side mould, a pulling ring mould, a main mould, an end socket plate blank, a lower mould, a base, an ejection cylinder, an end socket, a press stand column, a headpiece, a pressing side oil cylinder, a pulling ring oil cylinder, a main oil cylinder, a pressing side anvil head, a pulling ring anvil head and a main anvil head; the base is separately connected with an equipment foundation, the press stand column, the lower mould and the ejection cylinder; and the forming device comprises a lower mould, lug holes, a beam, an X axis, a Z axis, a Y axis, a stand column and a tool post. The multi-acting mould device adopts an electroslag re-melting technology to manufacture a mould body, so that a cracking phenomenon, due to cold shortness and hot shortness, of the mould is eliminated, and therefore, the service life, under high precision, of the mould is prolonged.

Description

technical field [0001] The invention relates to a mold manufacturing technology, in particular to a multi-movement mold device and a manufacturing method thereof. Background technique [0002] At present, conventional head press molds are generally installed on single-acting or double-acting hydraulic presses, air presses, hydraulic presses or mechanical presses; they are mainly used to press straight-sided oval heads, straight-sided disc-shaped heads, Straight-edged conical heads, straight-edged large and small openings, straight-edged eccentric cones, straight-edged spherical crowned heads, etc.; With the continuous application of new technologies, new processes and new methods, special or special-shaped head products have emerged, such as: transportation or storage tanks for high-risk liquids such as natural gas, ethers, and benzene, flammable and explosive liquids, and toxic and harmful liquids Body head products; not only the head is required to bear pressure, but also...

AI Technical Summary

Problems solved by technology

[0004] 1. The mold is made of castings. Because the material contains more sulfur and phosphorus, there are often cold and brittle cracks.

[0005] 2. If the mold uses electroslag remelting materials, the various processing tools produced by domestic and foreign manufacturers cannot meet the production conditions; The hardness is close; therefore, it is difficult to process the electroslag remelting material with ceramic tools or alloy steel or coated tools.

[0006] 3. The mold manufacturing cycle is long and the processing accuracy is low; that is, the conventional method is to use gouging for rough machining, and then use the grinding wheel for trimming and research. The manual workload is large, the production efficiency is low, the product quality is low, and the manufacturing cost is high.
