Description

A flip-chip composite mold based on spring unloading chain plate

technical field

The utility model relates to a spring-based unloading chain plate flip-chip composite mold, which belongs to the field of stamping dies and is mainly used for punching and blanking chain plates.

Background technique

The chain links of motorcycles and bicycles in life are composed of three parts: "rolling ring + chain plate + chain pin (chain shaft)", and the chain is composed of small chain links with such a structure. Among them, the chain plate is often obtained by punching, blanking and other multi-process stamping methods. But the more processes, the higher the production cost and the lower the precision. In order to reduce costs and improve precision, a flip-chip composite mold was invented in practical production, and the punching and blanking processes can be completed in one process.

Contents of the invention

Aiming at the above-mentioned problems in the prior art, the utility model provides a flip-chip composite mold with less production steps and relatively low design and manufacturing costs.

The technical scheme of the utility model is: an inverted compound mold based on the spring unloading chain plate, including a punching rod, a mold handle, an anti-rotation pin, a cylindrical pin, an upper mold seat, an upper mold backing plate, a punch fixing plate, Push block fixing plate, die, stripping plate, spring, punch and die fixing plate, lower die backing plate, lower die seat, unloading screw, punch and die, screw, positioning pin, guide post, guide sleeve, push block, convex Die, the mold shank is interference fit in the upper die seat, the knockout rod runs through the punch fixing plate, the upper die backing plate, and the die handle, and the cylindrical pin runs through the upper die seat, the upper die backing plate, the punch fixing plate, the pusher A fixed plate and the die, the positioning pin runs through the upper die base, the upper die backing plate, the punch fixing plate, the upper die base, the upper die backing plate, the punch fixing plate, the push block fixing plate and the die are connected with screws, The punch is placed between the backing plate of the upper die and the fixing plate of the punch, the guide sleeve and the upper die seat are in interference fit, the push block is placed between the fixing plate of the punch and the fixing plate of the push block; The fixing plate and the backing plate of the lower die are connected with unloading screws, the fixing plate of the convex and concave die, the backing plate of the lower die and the lower die are connected and fixed with screws, the punch and concave die are fixed on the backing plate of the lower die with screws, and the guide post is interference fit with the lower die seat.

The stripping plate and the fixed plate of the convex and concave dies are processed with 4 circular grooves for spring positioning.

The chain plate flip-chip composite mold described in the utility model is easy to use, punching and blanking can be completed in one process, and the design and manufacturing costs are low.

detailed description

As shown in Figure 1, the flip-chip composite mold based on the spring unloading chain plate includes a punching rod 1, a mold handle 2, an anti-rotation pin 3, a cylindrical pin 4, an upper mold base 5, an upper mold backing plate 6, a convex Die fixing plate 7, push block fixing plate 8, die 9, unloading plate 10, spring 11, punch and die fixing plate 12, lower die backing plate 13, lower die base 14, unloading screw 15, punch and die 16, screws 17. Locating pin 18, guide post 20, guide sleeve 22, push block 23, punch 26, mold handle 2 is interference fit in upper die base 5, punching rod 1 runs through punch fixing plate 7, upper die pad Plate 6, die handle 2, and cylindrical pin 4 run through upper die base 5, upper die backing plate 6, punch fixing plate 7, push block fixing plate 8 and die 9, and positioning pin 25 runs through upper die base 5, upper die base Die backing plate 6, punch fixing plate 7, upper die base 5, upper die backing plate 6, punch fixing plate 7, push block fixing plate 8 and die 9 are connected with screw 24, and punch 26 is placed on the upper die pad Between the plate 6 and the punch fixing plate 7, the guide sleeve 22 is in interference fit with the upper die base 5, and the push block 23 is placed between the punch fixing plate 7 and the push block fixing plate 8; the unloading plate 10, the spring 11, The convex and concave mold fixing plate 12 and the lower mold backing plate 13 are connected with the discharge screw 15, the convex and concave mold fixing plate 12, the lower mold backing plate 13 and the lower mold 14 are connected and fixed with the screw 19, and the convex and concave mold 16 is connected and fixed on the lower mold with the screw 17 The backing plate 13 and the guide post 20 are interference fit on the lower mold base 14 .

The stripping plate 10 and the punch and die fixing plate 12 are processed with 4 circular grooves for the positioning of the spring 11 .

The chain plate flips the compound mold, the mold handle 2 is fixed on the upper workbench of the punch press, and the lower mold base 14 is fixed on the lower workbench of the punch press. When the mold is working, the stamping steel sheet is first placed on the unloading plate 10, the worktable on the punching machine moves downward, the punch and die 16 first contact the punch 26 to complete the punching action, and the waste material falls from the hole of the lower die, and the punch and die die instantly 16 and the die 9 complete the blanking action; on the return journey of the workbench, the punching rod 1 touches the beam of the punch press, and the punching rod 1 moves downward to push the push block 23 to push out the workpiece in the die 9 .
