DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] The die-casting mold shedding mechanism provides two technical solutions:

[0024] like Figure 1 and 2 The first embodiment is shown: it includes an upper plate 1, an intermediate plate 2 and a base 3, a nozzle removal component 7 for removing the nozzle produced by die casting of the mold is arranged between the upper plate 1 and the intermediate plate 2, and an ejection component 8 for ejecting the finished product after processing is arranged inside the base 3, and columns 4 are fixedly connected at the four corners of the bottom of the upper plate 1, and the columns 4 penetrate the intermediate plate 2 and extend to the inside of the base 3, and four anti-wear mechanisms are arranged inside the intermediate plate 2, and the four anti-wear mechanisms are respectively located at the positions where the four columns 4 penetrate the intermediate plate 2, and the anti-wear mechanisms include:

[0025] The anti-wear component 5 includes a circular groove 51 opened on the top of the middle plate 2, a circular ring 52 is placed inside the circular groove 51, a plurality of ball grooves 53 are opened at equal distances inside the circular ring 52, and steel balls 54 are installed inside the plurality of ball grooves 53, a countersunk hole is opened outside the middle plate 2, and a locking bolt 55 is threadedly connected at the countersunk hole, and the locking bolt 55 passes through the middle plate 2 and extends to the inside of the circular groove 51, the column 4 passes through the inside of the circular ring 52, and the surface of the column 4 contacts with the plurality of steel balls 54, a first annular groove 56 is opened on the outer surface of the circular ring 52, and a second annular groove 57 is opened on the inner surface of the circular groove 51, and the position of the second annular groove 57 corresponds to that of the first annular groove 56.

[0026] When the column 4 slides and the workpiece falls off, the steel ball 54 in the anti-wear component 4 contacts the column 4, thereby reducing friction and avoiding the occurrence of severe wear, which is beneficial to the long-term use of the die-casting mold.

[0027] like Figure 1 and 3 The second embodiment is shown, which is mainly different from the first embodiment in that: a lubricating assembly 6 is provided, and the lubricating assembly 6 is used to lubricate the steel balls 54 in the anti-wear assembly 5. Four lubricating assemblies 6 are provided, and the four lubricating assemblies 6 are respectively arranged on the left and right sides of the middle plate 2. The lubricating assembly 6 includes an oil cylinder 61, and the right side of the oil cylinder 61 is fixedly connected with a bolt mounting pipe 62. The oil cylinder 61 is threadedly connected to the right side of the middle plate 2 through the bolt mounting pipe 62, and the oil cylinder 61 is connected to the inside of the second annular groove 57. The top of the oil cylinder 61 is fixedly connected with an oiling nozzle 67, the inner surface of the oil cylinder 61 is slidably connected with the first push plate 63 and the second push plate 64, a return spring 65 is fixedly connected between the two first push plates 63 and the second push plates 64, the oil cylinder 61 is located in a cavity on the right side of the first push plate 63 filled with lubricating oil, the left side of the oil cylinder 61 is threadedly connected with an adjusting bolt 66, the adjusting bolt 66 penetrates the oil cylinder 61 and extends to the inside of the oil cylinder 61, and one end of the adjusting bolt 66 located inside the oil cylinder 61 contacts the left side of the second push plate 64.

[0029] When in use, the ring 52 is placed inside the circular groove 51, and the locking bolt 55 is screwed into the countersunk hole. The position of the ring 52 is locked after the end of the locking bolt 55 contacts the ring 52. When the mold is opened and closed, the column 4 contacts the steel ball 54 and the steel ball 54 moves through friction. This contact method is beneficial to reducing friction. In addition, the lubricating oil in the oil cylinder 61 enters the cavity formed by the second annular groove 57 and the first annular groove 56 through the action of the reset spring 65, and takes the lubricating oil away when the steel ball 54 moves, and enters between the steel ball 54 and the column 4 for lubrication. In addition, the adjusting bolt 66 is turned to move the second push plate 64, thereby helping to drain the lubricating oil in the oil cylinder 61.
