Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of die blank, specifically relates to a die blank of multistage locking. BACKGROUND

[0002] Die blank is the skeleton of a complete set of molds. It is a key part of mold manufacturing and a product of applying mold theory and technology to actual manufacturing process. Die blank is made of metal materials such as steel and aluminum alloy, has good wear resistance, corrosion resistance and high strength, and can withstand complex processing technology and high temperature and high pressure environment. Die blank is an important tool for manufacturing industrial products, and its cost usually accounts for about 30% of the cost of a complete set of molds. Die blank is manufactured by a special large die blank factory, which has been standardized, and each mold manufacturing factory only needs to customize it according to its own needs.

[0003] In the current die blank design, the upper die seat and the lower die seat are both assembled by a plurality of independent metal blocks. Due to the large number of corner parts of the upper die seat, some die blanks are provided with a reinforcing bar on each side of the upper die seat to reinforce all units as a whole. However, the current connection mode between the reinforcing bar and the upper die seat is mainly through a bolt directly screwed and connected. This connection mode has obvious problems when the bolt size is long: the long bolt is easy to be pushed into the upper die seat during tightening, and when the tightening force is too large, it will also cause damage to the inside of the upper die seat. Therefore, we need to make necessary improvements to ensure the stability and safety of the die blank structure. UTILITARIAN CONTENT

[0023] Preferably, a notch 201 is formed on one side of the top end of upper die seat 2, and a butt joint 202 is formed on the upper and lower two independent templates of lower die seat 1.

[0024] When used, the butt joint 202 is formed on the upper and lower two independent templates, the plug rod 4 and the threaded column 401 pass through the third installation port 303 and are screw-connected with the butt joint 202, so that the overall firmness of the upper template after installation can be enhanced.

[0025] Preferably, a first installation port 301 is formed in the locking plate 3, a second installation port 302 is formed in the locking plate 3 on the longitudinal sides of the first installation port 301, and the other side of the second installation port 302 is communicated with the bottom of the third installation port 303. Two moving blocks 11 are symmetrically installed in the first installation port 301, an extrusion screw 5 is arranged between the two moving blocks 11, a moving rod 7, a movable ring 9 and a spring 10 are installed in the second installation port 302, a fixed ring 8 is further fixedly installed on the inner wall of the second installation port 302 on one side of the movable ring 9, and the moving rod 7 movably penetrates the two sides of the fixed ring 8.

[0026] When used, the end of the two moving blocks 11 on the opposite side is semicircular, and the bottom of the extrusion screw 5 is also semicircular.

[0027] The minimum inner diameter size of the second installation port 302 is matched with the diameter size of the moving rod 7, the moving rod 7 movably sleeves the spring 10, and the maximum diameter size of the spring 10 and the fixed ring 8 is matched with the maximum inner diameter size of the second installation port 302.
