Description

Technical Field

[0001] This utility model relates to the field of fastener processing technology, specifically a tooling that facilitates increasing the upper die push stroke. Background Technology

[0002] Over the past three decades, the rapid development of the metallurgical, machinery, and electronics industries has driven the upgrading of global fastener products and the continuous progress of the fastener industry. Especially in recent years, fastener products have become increasingly complex, and the requirements for new products have become increasingly stringent. Existing machining fixtures lack sufficient ejection stroke to meet the processing needs of new fasteners. For example... Figure 1 As shown, the upper ejection stroke of the equipment is only 25mm, but the product's stripping stroke is 28mm. Redesigning a new machining fixture with a longer ejection stroke would significantly increase production costs. The existing equipment cannot meet the product requirements, resulting in significant idle time and waste. To solve this problem, the existing fixture can be redesigned to increase its upper die ejection stroke. Summary of the Invention

[0003] The purpose of this invention is to provide a tooling that facilitates increasing the upper die ejection stroke, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A tooling for increasing the upper die ejection stroke includes a main die and an upper die shell. The main die has a lower punch inside, and the upper die shell has an upper punch, an upper punch pad, and an upper punch sleeve inside. An upper die pad is located on the left side of the upper die shell. An upper punch ejector rod that can move left and right is located inside the upper die pad. A receiving cavity is located inside the receiving cavity. A spring is located inside the receiving cavity and is sleeved on the upper punch ejector rod. An upper die ejection pad is located below the upper punch ejector rod. An upper die ejection pad sleeve is located outside the upper die ejection pad. The length of the upper die ejection pad sleeve is greater than that of the upper die ejection pad. An upper die ejection pin is located on the right side of the upper die ejection pad. An upper punch ejector tube is located on the right side of the upper die ejection pin. The upper punch ejector tube is sleeved outside the upper punch. The upper die ejection pin moves left and right through the upper die ejection pad and the upper punch sleeve. The upper die ejection pin pushes the upper punch ejector tube to move left and right along the upper die shell.

[0005] Furthermore, one end of the spring is connected to the receiving cavity, and the other end is connected to the upper mold push pad.

[0006] Furthermore, the left end of the upper punch tube is provided with a boss, and the interior of the upper mold shell is provided with a limiting step that cooperates with the boss.

[0007] Furthermore, the inner diameters of the upper die pusher pad, the upper die pad block, and the upper punch sleeve are equal, and their outer diameters are equal.

[0008] Preferably, the upper mold ejector pin has a cylindrical structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: After molding, the upper mold exits the main mold to the left. At this time, the upper punch rod is pushed to the right. The upper punch rod pushes the upper mold push pad, the upper mold push pad pushes the upper mold push pin, and the upper mold push pin pushes the upper punch tube. Under the linkage, the blank is left in the main mold. Through improvement, the upper mold push stroke is increased on the basis of the existing tooling to meet the processing requirements of new fasteners. Attached Figure Description

[0015] Please see Figure 2-5 A tooling for facilitating increased upper die ejection stroke includes a main die 9 and an upper die shell 5. The main die 9 contains a lower punch 10, and the upper die shell 5 contains an upper punch 7, an upper punch pad 12, and an upper punch sleeve 6. An upper die pad 2 is located on the left side of the upper die shell 5. An upper punch ejector rod 1, which can move left and right, is located within the upper die pad 2. A receiving cavity is located within the receiving cavity, and a spring 3 is installed within the receiving cavity. The spring 3 is sleeved on the upper punch ejector rod 1. An upper die pusher is located below the upper punch ejector rod 1. Material pad 4, upper mold push pad 4 is provided with upper mold push pad sleeve 14 outside upper mold push pad 4, upper mold push pad sleeve 14 is longer than upper mold push pad 4, upper mold push pin 13 is provided on the right side of upper mold push pad 4, upper punch push tube 8 is provided on the right side of upper mold push pin 13, upper punch push tube 8 is sleeved on the outside of upper punch 7, upper mold push pin 13 passes through upper mold push pad 4 and upper punch sleeve 6 and moves left and right, upper mold push pin 13 pushes upper punch push tube 8 to move left and right along upper mold shell 5.

[0016] One end of the spring 3 is connected to the receiving cavity, and the other end is connected to the upper die pusher pad 4. The left end of the upper punch push tube 8 is provided with a boss, and the interior of the upper die shell 5 is provided with a limiting step that mates with the boss. The inner diameters and outer diameters of the upper die pusher pad sleeve 14, the upper die pad block 2, and the upper punch sleeve 6 are equal. The upper die pusher ejector pin 13 is a cylindrical structure.

[0017] like Figure 2 , 3 As shown, in the mold-closed state, the upper mold and the main mold are closed, and the upper and lower punches work together to form the blank 11. At this time, the upper punch reaches the maximum stroke position.

[0018] After molding, the upper mold retracts to the left from the main mold. At this time, the upper punch is pushed to the right, which pushes the upper mold push pad, which in turn pushes the upper mold push pin. The upper mold push pin then pushes the upper punch tube, thus leaving the blank 11 inside the main mold 9. Figure 4 , 5 As shown, the spring is stretched at this time.

[0019] After completion, release the upper punch rod, the spring retracts, and the upper punch rod, upper mold push pad, upper mold push pin, and upper punch push tube return to their original positions, ready for the next forming.
