Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1, the present embodiment is a mold for forming a multi-directional cross change part, including a forming mold, an automatic blowing device 1 and a machine electromagnetic valve 2 connected to the automatic blowing device 1, and is characterized in that: the automatic blowing device 1 is communicated with the forming die, the forming die comprises an upper die 3 and a lower die, the upper die 3 comprises an upper die holder 31, an upper die plate 32 fixed on the upper die holder 31 through a fixing pin, an upper punch mounting seat 33 fixedly mounted on the upper die plate 32 and an upper punch 34 fixedly mounted on the upper punch mounting seat 33, the lower die comprises a lower die holder 41, a lower die plate 42 fixed on the lower die holder 41 through a fixing pin, a die ring 43 fixedly mounted on the lower die plate 42 through a fixing pin, a synchronous insert 44, a die block 45, a synchronous oblique block 46 and a lower punch 47, the die block 45 is arranged in the die ring 43 and fixed on the lower die plate 42, the synchronous insert 44 is arranged in the die ring 43, the lower punch 47 is mounted in the die ring 43 through a lower punch fixing seat, and the upper half part of the lower punch 47 penetrates through the synchronous insert 44, the synchronized swash block 46 is disposed at an upper portion inside the mold ring 43, and the synchronized swash block 46 is divided into a left synchronized swash block mold half 461 and a right synchronized swash block mold half 462, and a workpiece 5 is placed between the left synchronized swash block mold half 462 and the right synchronized swash block mold half 462. The electromagnetic valve 2 of the machine table is connected with a multistage linkage powerful differential ejection device, so that after a part is formed in a mold, the part is subjected to initial large ejection force demolding, and the cylinder in the later stage is rapidly ejected, so that the action time is shortened, and ejection is completed.

The automatic material blowing device 1 comprises an air gun nozzle 11 and a material blowing nozzle 12, the die ring 43 is provided with an air jet hole 6, and the material discharging nozzle 12 is communicated with the air jet hole 6 of the die ring 43.

An ejector pin fixing seat 7 is arranged in the lower template 42, an ejector pin 71 is fixedly mounted on the ejector pin fixing seat 7, the head of the ejector pin 71 is connected with the bottom of the synchronous insert 44, and a return drag hook 72 is connected to the bottom 7 of the ejector pin fixing seat.

An inner cavity is formed between the left syncline swash block half 461 and the right syncline swash block half 462.

When the mold is implemented, the workpiece is formed by two synchronous inclined slide block half molds, and the electromagnetic valve of the machine table is connected in series with the automatic opening and closing mold and the automatic blowing mold in one go, so that the mold is high in efficiency, low in cost, safe and high in yield. After the upper die is assembled, the forming of a workpiece 5 is completed, the electromagnetic valve 2 of the machine table is controlled by a travel switch of the machine table, after a part is formed, the friction force of the synchronous inclined block 46 and the die ring 43 is very large, and almost no lower ejection device exists in a punch press, so that the electromagnetic valve is directly connected with a multistage linkage strong differential ejection device, after the part is formed in the die, the initial large ejection force is provided for demolding, and the later cylinder is rapidly ejected, so that the action time is shortened, after the ejection is completed, high-pressure gas in the cylinder can be instantly released when the electromagnetic valve is reversed during the action, after the die is ejected, the part stays in the die cavity, the workpiece is just blown out of the die cavity by the high-pressure gas of the cylinder, and is simultaneously connected with the gas blow pipe gas gun nozzle 11 and the blow joint 12, the blow joint 12 blows the workpiece 5 out of the die cavity, and the blow joint 12 blows the blown workpiece out of the die from the working surface, the damage of the die caused by pressing the material on the die closing surface when the upper die closes the die next time is avoided.

After the synchronous inclined block 46 is ejected by the ejection device, the left synchronous inclined block half mould 461 and the right synchronous inclined block half mould 462 automatically open, the workpiece is smoothly blown out by using high-pressure gas of the acted cylinder, and meanwhile, when the ejected cylinder returns, the lower return drag hook 72 can be pulled, a certain pulling force can be generated in the return stroke of the cylinder, the thimble 71 connected with the drag hook and the synchronous insert 44 are connected together, the ejected synchronous inclined block 46 can be simultaneously pulled back into the mould ring 43, so that a certain wrapping force is generated per se, and the workpiece does not return to generate burrs during forming. The operation workman only need can produce fast toward blowing in the mould, even there is the debris of dust to drop the die cavity in production, air gun nozzle 11 blows off the dust on the material joint 12 with die cavity and die joint face with blowing out, makes it can not cause the part surface bad, has effectively reduced workman's the amount of labour.
