Detailed Embodiment

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the present utility model provides the following technical solutions:

[0030] Embodiment 1: The existing blanking die for machining automobile engine valve bodies is not convenient for rapid cooling. To solve this technical problem, the following technical content is disclosed in this embodiment:

[0031] A blanking die for machining automobile engine valve bodies includes a base 1, a support auxiliary component 5, an out-molding auxiliary component 7, and a three-stage cylinder 8. A fixed column 2 is fixedly installed at the top end of the base 1. A support auxiliary component 5 is arranged inside the fixed column 2. A dry ice smoke machine 3 is installed at the top end of the base 1. The top end of the dry ice smoke machine 3 is connected to an operating table 4. A lower die 6 is fixedly installed at the top end of the operating table 4. An out-molding auxiliary component 7 is installed inside the lower die 6. An upper blanking die 9 is arranged at the top end of the lower die 6. The top end of the upper blanking die 9 is fixedly installed with a three-stage cylinder 8, and the three-stage cylinder 8 is fixedly installed inside a top seat 10;

[0032] As Figures 1-3 shown, the dry ice smoke machine 3 includes a main body 301 and a connecting pipe 302. The main body 301 is installed at the top end of the base 1. The top end of the main body 301 is fixedly connected to the connecting pipe 302. The top end of the connecting pipe 302 penetrates through the operating table 4 and is arranged at the bottom outside the lower die 6. When cooling the lower die 6 and the blanked material inside it, turn on the switch of the main body 301, and the dry ice smoke in the main body 301 is blown from the connecting pipe 302 to the bottom of the lower die 6, so as to perform rapid cooling treatment;

[0033] Embodiment 2: The existing blanking die for machining automobile engine valve bodies is not convenient for out-molding and material taking. To solve this technical problem, the following technical content is disclosed in this embodiment:

[0034] As Figure 1 , Figures 3-5 shown, the out-molding auxiliary component 7 includes a bottom plate 701 and a spring 702. The bottom plate 701 is arranged inside the lower die 6. The material to be blanked is placed on the top end of the bottom plate 701 for blanking. After blanking, the upper blanking die 9 leaves the lower die 6. A spring 702 is fixedly connected to the bottom of the bottom plate 701. The end of the spring 702 away from the bottom plate 701 is fixedly connected to the bottom inside the lower die 6. The bottom plate 701 is driven by the spring 702 to bounce up, so that the blanked material at its top end is ejected from the lower die 6, thus facilitating out-molding and material taking;

[0035] Embodiment 3: The overall structure of the existing blanking die for machining automobile engine valve bodies is not very stable. To solve this technical problem, the following technical content is disclosed in this embodiment:

[0036] As Figures 1-3 and Figure 6 shown, the support and auxiliary component 5 includes a triangular support block 501 and a fixing frame 502. The three-stage cylinder 8 includes a cylinder body 801 and a connecting plate 802. One right-angled side of the triangular support block 501 is fixedly installed inside the fixing column 2. The other right-angled side of the triangular support block 501 is fixedly installed at the top of the base 1, the top of the operating table 4, and the bottom end of the top seat 10 respectively. The triangular support block 501 improves the supporting force of the fixing column 2. The cylinder body 801 is fixedly installed inside the top seat 10. A fixing frame 502 is fixedly installed on the outer side of the part of the cylinder body 801 located above the top seat 10. The bottom of the fixing frame 502 is fixedly installed with the top seat 10, which improves the connection stability between the cylinder body 801 and the top seat 10. The three output ends of the cylinder body 801 are fixedly connected with the connecting plate 802. The three output ends make the connection of the connecting plate 802 more stable. The bottom of the connecting plate 802 is fixedly connected with the blanking upper die 9, thus preventing the blanking upper die 9 from skewing during the blanking process;

[0037] Working principle: Place the material to be blanked on the top of the connecting plate 802, start the three-stage cylinder 8, and its output end drives the blanking upper die 9 to move downward towards the lower die 6 for blanking. After the blanking is completed, start the three-stage cylinder 8 again, and it drives the blanking upper die 9 to move upward to leave the inside of the lower die 6. At the same time, turn on the body 301 of the dry ice smoke machine 3 to cool the lower die 6 and the material inside it. At the same time, the spring 702 jacks up the bottom plate 701, so that part of the blanked material is ejected, which is convenient for the staff to take it out.

[0038] The above completes a series of operations of the blanking die for machining automobile engine valve bodies. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
