DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] 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 creative efforts shall fall within the protection scope of the present utility model.

[0019] According to Figures 1-4 As shown, it includes a mold base 1. Mold grooves 11 are provided at both positions on the top end of the mold base 1 near the two sides, and sinking grooves 12 are provided at the inner walls of the bottoms of the two groups of mold grooves 11 near one end. One end of each of the two groups of mold grooves 11 is open. A communication hole 13 is provided at the position near the middle on one side inside the mold base 1, and an annular groove 15 is provided at the inner wall of the communication hole 13 near the middle.

[0020] A motor 2 is installed at the position near one end on one side of the mold base 1, and the output end of the motor 2 is drivingly connected to a rotating shaft 21. One end of the rotating shaft 21 passes through the inner side of one side of the mold base 1 through the communication hole 13, and the end of the rotating shaft 21 is installed on the inner wall of one side of one of the mold grooves 11 through a bearing seat 14. A limiting ring 22 is installed at the position near the middle on the outer surface of the rotating shaft 21, and mounting rollers 23 are installed at the positions near the two sides on the outer surface of the rotating shaft 21. The outer diameter of the limiting ring 22 is adapted to the inner diameter of the annular groove 15, and the limiting ring 22 is arranged inside the annular groove 15 and is slidably connected thereto. Baffles 24 and stripping plates 25 are installed on the outer surfaces of the mounting rollers 23, and the included angle between the baffle 24 and the stripping plate 25 is set to a right angle. The number of the stripping plates 25 is two groups, and the two groups of stripping plates 25 are respectively placed inside the corresponding sinking grooves 12, and the top surface of the stripping plate 25 is flush with the inner wall of the bottom of the mold groove 11.

[0021] An installation ring 3 is installed on the side surface of the motor 2, and a support rod 31 is installed on one side of the installation ring 3. The shape of the support rod 31 is L-shaped. The inner side of the support rod 31 is installed on one end of the mold base 1, and a connecting rod 32 is installed on the outer side of the support rod 31. A support plate 33 is installed at the bottom end of the connecting rod 32, and two installation plates 34 are installed at the top end of the support plate 33.

[0022] The arrangement of the baffle plate 24 and the stripper plate 25 can make the four sides and the bottom of the mold groove 11 all closed, so that the tin bar can be injection molded inside the mold groove 11. After the tin bar inside the mold groove 11 is injection molded, the user can start the motor 2, so that the rotating shaft 21 can rotate accordingly under the operation of the motor 2, so that the limit ring 22 can rotate accordingly inside the annular groove 15, so that the rotating shaft 21 is more stable and less likely to shake when rotating, so that the two sets of mounting rollers 23 and the two The baffle plate 24 and the two stripping plates 25 can respectively rotate accordingly inside the corresponding sinking groove 12. When the one side surface of the two baffle plates 24 is respectively in contact with the one side surface of the corresponding two diagonal support plates 36, the motor 2 can be stopped. In this process, since the two stripping plates 25 rotate, the ends of the tin bars located inside the two groups of mold grooves 11 will be supported by the corresponding stripping plates 25, so that the ends of the corresponding tin bars can be lifted up, thereby facilitating the demolding operation from the inside of the corresponding mold groove 11.

[0023] The motor 2 can be supported by the arrangement of the mounting ring 3 and the support rod 31, so that the motor 2 can be stably installed on one side of the mold base 1. The two groups of mounting plates 34 can be supported by the support rod 31, the connecting rod 32 and the support plate 33, so that when one side surface of the two groups of baffles 24 are respectively in contact with one side surface of the corresponding two groups of diagonal support plates 36, the corresponding support column 35 and the corresponding mounting plate 34 can be stably supported.
