Detailed Description

Referring to fig. 1, 2, 3 and 4, the novel combined die for casting comprises a die fixing frame 1, a die 2, a sink 3 and a positioning piece 4. The die fixing frame 1 is a square plate, and four sinking grooves 3 are distributed on the die fixing frame 1 in central symmetry and close to four corners; the sink 3 is of a square structure; the supporting part of the mould 2 is also of a square structure; the size of the sinking groove 3 is matched with or slightly larger than that of the mould 2 with the largest size. Each sinking groove 3 comprises four L-shaped supporting walls, a mold 2 is placed on the two L-shaped supporting walls close to the central part of the mold fixing frame 1, and threaded holes 6 are respectively formed in the vertical walls of the two L-shaped supporting walls far away from the central part of the mold fixing frame 1. Each threaded hole 6 faces a side wall of the die 2. The number of the positioning pieces 4 is 8, and each positioning piece 4 comprises a supporting rod 4-1, an L-shaped supporting plate 4-2 and a connecting rod 4-3. Each support rod 4-1 is provided with a thread section; each of which is threaded in a co-operating threaded bore 6. One end of the support rod 4-1 close to the sinking groove 3 is provided with a T-shaped groove; one end of the connecting rod 4-3 is fixedly connected with the L-shaped supporting plate 4-2, and the other end of the connecting rod is provided with a cylindrical T-shaped block; the T-shaped block is coaxially and rotatably connected in the T-shaped groove, so that the support rod 4-1 is screwed in the threaded hole 6, and when the L-shaped support plate 4-2 is driven to move towards the inner part of the sinking groove 3, the L-shaped support plate 4-2 only horizontally moves but does not radially rotate, and the L-shaped support plate 4-2 is more stable to control the mold 2. The two L-shaped supporting plates 4-2 positioned in the sinking groove 3 and the two L-shaped supporting walls close to the center of the die fixing frame 1 in the sinking groove 3 jointly fix the die 2, and the position of the L-shaped supporting plates 4-2 is adjustable, so that the sinking groove 3 can be adapted to the dies 2 with various specifications. And a casting groove 5 is arranged at the central position of the die fixing frame 1. The casting groove 5 comprises a central circular groove and four first bar-shaped grooves. Each mould 2 is provided with a second strip-shaped groove. The central circular groove is positioned at the central position of the fixed frame 1 of the mold and is respectively communicated with the four molds 2 through four first strip-shaped grooves and four second strip-shaped grooves, so that the molds 2 can be cast quickly.

For a clearer description of the beneficial effects of the present invention, the following description is provided in conjunction with the specific operation steps of the present invention in the actual use process.

Referring to fig. 1, 2, 3 and 4, the novel combined die for casting is used as follows: firstly, placing a mould fixing frame 1 at a casting position; secondly, placing the required moulds 2 with different specifications in a sink 3, and screwing a support rod 4-1 to enable an L-shaped support plate 4-2 to fix the moulds 2; and thirdly, pouring the cast molten iron into the central circular groove of the casting groove 5, flowing through the four first strip-shaped grooves, and then flowing through the four second strip-shaped grooves to enter the four molds 2. And finishing the casting work after the molten iron is shaped. In order to prepare different end covers, the die 2 can be replaced randomly before molten iron is cast according to requirements, and the replacement can be realized only by replacing the die 2 through the thread adjusting positioning piece 4, so that the operation is simple and convenient.
