Description

Technical Field

[0001] This application relates to the field of mold forming technology, specifically to a mold for forming irregular pistons. Background Technology

[0002] As the core component of pneumatic equipment, the molding quality of the cylinder piston directly affects the performance of the equipment, and mold technology is the key to ensuring molding accuracy and efficiency.

[0003] Existing molding dies generally include a fixed mold and a moving mold. By filling the cavity between the fixed mold and the moving mold with liquid metal, the corresponding cylinder piston is formed. However, traditional molds are only suitable for forming conventional standard cylinder pistons. For complex and irregular irregular pistons, it is difficult to remove the mold after forming a complete irregular piston using traditional molds. If only the approximate shape is formed, a large number of subsequent processing steps are still required to obtain a complete irregular piston, which is not only inefficient but also costly. Utility Model Content

[0004] To address the aforementioned problems, this application provides a non-circular piston forming mold that can form a complete non-circular piston in one step, reducing subsequent processing steps, lowering costs, and improving production efficiency. The technical solution adopted is as follows:

[0005] An irregularly shaped piston forming mold includes a first mold body and a second mold body that can move closer to or further away from the first mold body along a first direction;

[0006] A third mold body that can move along a second direction is provided between the first mold body and the second mold body; the first mold body, the second mold body and the third mold body form a cavity adapted to the irregular piston, and the second mold body is provided with a liquid inlet communicating with the cavity;

[0007] A linkage component, which connects the second mold and the third mold;

[0008] When the second mold approaches or moves away from the first mold, the linkage component can synchronously drive the third mold to approach or move away from the liquid inlet along the second direction.

[0009] Preferably, it further includes a guide assembly for guiding the movement of the third mold body; the guide assembly includes a baffle and a movable block detachably connected to the third mold body, the movable block being slidably connected to the baffle.

[0010] More preferably, the first mold body is provided with a receiving groove for accommodating the guide component, and the baffle is connected to the first mold body.

[0011] Preferably, the linkage assembly includes an inclined through hole and a linkage rod disposed within the through hole for driving the third mold body to move.

[0012] Preferably, both the first mold body and the second mold body include a support part and a casting mold, and the support part is provided with a placement groove, and the casting mold is detachably connected to the placement groove.

[0013] Preferably, a limiting component is provided between the first mold and the second mold to guide the movement direction of the second mold and limit the position of the second mold.

[0014] More preferably, it further includes a positioning component for limiting the position between the molds.

[0015] The beneficial effects of this application are as follows:

[0016] (1) This application provides a third mold between the first mold and the second mold, and the three form a cavity that matches the irregular piston. When the molding is completed, the third mold can open in two directions simultaneously with the second mold, so that the irregular mold can be taken out smoothly. The irregular piston can be molded in one step, thereby reducing costs and reducing subsequent processing steps, thus improving production efficiency.

[0017] (2) Both the first mold and the second mold include a support part and a mold for disassembling and connecting the support part, and the third mold is disassembled and connected to the guide assembly. Therefore, it can be used to mold irregular pistons of different specifications and sizes, and the general shape is better. Attached Figure Description

[0032] Combination Figure 2 A shaped piston forming mold includes a first mold body 10 and a second mold body 20 that can move closer to or further away from the first mold body 10 along a first direction. The second mold body 20 is provided with a liquid inlet 50. Casting medium (such as molten aluminum) enters between the first mold body 10 and the second mold body 20 through the liquid inlet 50. The second mold body 20 may be driven by a fixedly installed power component, which may be a cylinder.

[0033] Combination Figure 3 A third mold 30 that can move along a second direction is provided between the first mold 10 and the second mold 20; the first mold 10, the second mold 20 and the third mold 30 form a cavity 300 adapted to the irregular piston 00, and the liquid inlet 50 is connected to the cavity 300.

[0034] It also includes a linkage component 40, which connects the second mold 20 and the third mold 30; when the second mold 20 approaches or moves away from the first mold 10, the linkage component 40 can synchronously drive the third mold 30 to approach or move away from the liquid inlet 50 in a second direction.

[0035] This application provides a third mold 30 between the first mold 10 and the second mold 20, forming a cavity 300 that matches the irregular piston 00. When the molding is completed, the third mold 30 moves in tandem with the second mold 20 and can open in two directions simultaneously, so that the irregular piston 00 can be easily removed. This allows the irregular piston 00 to be molded in one step, thereby reducing costs and reducing subsequent processing steps, thus improving production efficiency.

[0036] Combination Figure 3 and Figure 4 In this embodiment, a guide assembly 60 is further included for guiding the movement of the third mold 30. The guide assembly 60 includes a baffle 620 and a movable block 610 detachably connected to the third mold 30. The movable block 610 is slidably connected to the baffle 620. The baffle 620 has a groove on its inner side, and the movable block 610 has a slider that slides along the groove.

[0037] The first mold 10 is provided with a receiving groove to accommodate the guide component 60, and the baffle 620 is connected to the first mold 10. The guide component 60 is embedded in the movable block 610, which can reduce the overall volume and the space occupied.

[0038] Combination Figure 3 The linkage assembly 40 includes an inclined through hole 420 and a linkage rod 410 disposed within the through hole 420 for driving the third mold body 30 to move. The through hole 420 is inclined along a second direction away from the liquid inlet 50; the through hole 420 includes a first placement hole on the first mold body 10 and a second placement hole on the movable block 610, the first placement hole and the second placement hole being coaxially arranged, and the linkage rod 410 being movable within the second placement hole.

[0039] Combination Figure 5 Both the first mold body 10 and the second mold body 20 include a support part 100 and a casting mold 200. The support part 100 is provided with a placement groove 400. The casting mold 200 is detachably connected to the placement groove 400, which can reduce the overall volume.

[0040] The cavity 300 is formed between the mold 200 and the third mold body 30. Figure 1The irregularly shaped piston 00 includes a first structure A and a second structure B. The first structure A has a rack-like structure, and the second structure B has an irregular cavity. The molds 200 form the first structure A and the second structure B, as well as the rack-like structure on the first structure A. The third mold 30 forms the irregular cavity on the second structure B. After molding, the third mold 30 moves out of the irregular cavity so that the irregularly shaped piston 00 can be removed. The molds 200 are detachably connected to the support 100, and the third mold 30 is detachably connected to the guide assembly 60, making replacement convenient. Therefore, it can be used to mold irregularly shaped pistons 00 of different specifications and sizes, offering better versatility.

[0041] After the casting medium injected into the cavity 300 through the liquid inlet 50 cools and solidifies, the second mold 20 opens and moves away from the first mold 10 along the first direction. The third mold 30, through the linkage component 40, synchronously follows the second mold 20 and moves away from the liquid inlet 50 along the second direction.

[0042] In some embodiments, a limiting component 70 is provided between the first mold body 10 and the second mold body 20 to guide the movement direction of the second mold body 20 and limit its position. The limiting component 70 may include a limiting post and a limiting hole coaxially arranged. The limiting post may be disposed on the first mold body 10, and the limiting hole may be disposed on the second mold body 20, with the limiting post sleeved within the limiting hole.

[0043] In some embodiments, a positioning component 70 is further included, which is used to limit the position between the molds 200. The positioning component 70 may include a slot and a block; the slot may be provided on the second mold body 20 or the first mold body 10 to improve molding accuracy.

[0044] In some embodiments, a feeding assembly is further included, which is disposed on the first mold body 10 and is used to push the irregular piston 00 away from the first mold body 10 so as to remove the irregular piston 00 from the first mold body 10; wherein, the feeding assembly includes a push rod that can penetrate the first mold body 10 and extend into the cavity 300.
