[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 8 The utility model provides a technical solution: a progressive forming mold for the production of a rotary tiller blade, comprising a base 1, a mounting block 2 is fixedly connected to the top of the base 1, a mounting block 2 is fixedly connected to the output end of the base 1, the right side of the mounting block 2 4 is slidably connected to the inner right part of the base 1, a female mold 3 is installed on the upper side of the mounting block 2, and a male mold 5 is installed on the bottom end of the mounting block 2 4.

[0026] The base 1 limits the mounting block 2 4, so that the mounting block 2 4 will not shift when moving, and further the female mold 3 and the male mold 5 will not shift when they are molded together, so that the production and processing quality of the rotary tiller is higher, and the production steps are reduced, so that the production efficiency is improved, and human resources are saved to reduce the employment cost.

[0027] Embodiment 2

[0028] On the basis of Example 1, in order to facilitate the replacement of the mother mold 3, two slide grooves 19 are opened on the internal upper side of the mounting block 2, and the slide grooves 19 are slidably connected to the inside of the slide grooves 19. The two slide blocks 18 are respectively fixedly connected to the left and right sides of the bottom end of the mother mold 3, and a switch door 9 is hinged inside the front end of the mounting block 2, and the rear side of the switch door 9 is in contact with the front side of the slide block 18.

[0029] The slide groove 19 limits the internal slider 18, so that the slider 18 can slide stably. By sliding the slider 18 into the slide groove 19, the mother mold 3 can be installed on the mounting block 2. At this time, by closing the switch door 9, the mother mold 3 can be stably installed on the upper side of the mounting block 2.

[0030] Embodiment 3

[0031] On the basis of Example 2, in order to achieve a more stable installation of the mother mold 3, the front end of the mounting block 2 is fixedly connected to two connecting blocks 6, the upper side of the connecting block 6 is fixedly connected to a rubber block 7, the bottom end of the rubber block 7 is fixedly connected to a leather rope 8, and the leather rope 8 is slidably connected to the inside of the connecting block 6, the outside of the leather rope 8 is slidably connected to the inside of the switch door 9, the end of the leather rope 8 away from the rubber block 7 is fixedly connected to a pull ring 11, and two placement grooves 10 are provided on the rear side of the switch door 9, and the outside of the rubber block 7 is engaged with the inside of the placement groove 10.

[0032] When the mother mold 3 needs to be replaced, the handle on the pull ring 11 and the front side of the switch door 9 is placed with fingers, and the handle and the pull ring 11 on the switch door 9 are pulled downward, so that the leather cord 8 can be stretched, and the leather cord 8 can pull the rubber block 7 to deform. At the same time, when the switch door 9 rotates, the rubber block 7 can be detached from the inside of the placement groove 10, so that the switch door 9 no longer restricts the slider 18, and the two leather cords 8 are arranged between the two sliders 18, so that the leather cords 8 will not affect the normal withdrawal of the mother mold 3. On the contrary, when the slider 18 slides into the inside of the slide groove 19, the switch door 9 is closed, so that the rubber block 7 can be engaged with the inside of the placement groove 10, so that the mother mold 3 will not be offset, thereby improving the mold closing accuracy and thus improving the production and processing quality.

[0033] Embodiment 4

[0034] On the basis of Example 3, in order to facilitate the replacement of the male mold 5, two limit grooves 12 are opened inside the mounting block 24, and the front end of the mounting block 24 is rotatably connected to the rotating shaft 13. Two pull ropes 14 are fixedly connected to the outside of the rotating shaft 13, and the outside of the pull rope 14 is slidably connected to the inside of the limit groove 12. A spring 15 is sleeved on the outside of the pull rope 14, and a clamping block 16 is fixedly connected to the side of the pull rope 14 away from the rotating shaft 13. One end of the spring 15 is fixedly connected to the inner wall of the limit groove 12, and the other end of the spring 15 is fixedly connected to the side of the clamping block 16 close to the rotating shaft 13. The outside of the clamping block 16 is slidably connected to the inside of the limit groove 12, and two push blocks 17 are fixedly connected to the top of the male mold 5, and the outside of the clamping block 16 is engaged with the inside of the push block 17.

[0035] When the male mold 5 needs to be replaced, the rotating shaft 13 is rotated so that the rotating shaft 13 can wrap the two pull ropes 14 around its outside, and then the pull ropes 14 can pull the clamping block 16 to squeeze the pull ropes 14 and detach from the inside of the push block 17. At this time, the male mold 5 is pulled downward, so that the male mold 5 can be conveniently disassembled, and then the push block 17 at the top of other types of male molds 5 is slid into the inside of the mounting block 2 4, so as to release the rotating shaft 13. At this time, the spring 15 can make a reset movement, and then the spring 15 can push the clamping block 16 to engage with the inside of the push block 17, so that the male mold 5 can be conveniently replaced. The female mold 3 and the male mold 5 are used in conjunction with each other. When producing and processing other types of rotary tillers, the female mold 3 and the male mold 5 need to be replaced.

[0036] In actual use, by using the male mold 5 and the female mold 3 to close the mold, the plate can be processed into a rotary blade at one time, so there is no need to process and produce it according to the five steps of transmission. This not only reduces the labor intensity of workers, but also saves human resources, reduces labor costs, and greatly improves processing efficiency, making it more economical to use.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
