[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and manufactures metal materials, composite materials and various types of products through forming and sintering.

[0003] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0004] When opening the existing powder metallurgy mold, usually only one direction is set for opening the mold. The mold that has been cooled and formed in the mold may adhere to the powder metallurgy mold, making it difficult to open the mold from this single direction.

[0005] Based on this, the applicant considered designing a powder metallurgy mold with multi-directional mold opening. Utility Model Content

[0025] Compared with the prior art, the utility model has the advantages of a powder metallurgy mold with multi-directional mold opening:

[0026] By setting up the bottom plate 100, the first side plate 200, the second side plate 300 and the transmission mechanism, it is achieved that the first side plate 200 and the second side plate 300 can simultaneously move closer to and farther away from the bottom plate 100 under the drive of the transmission mechanism, and the direction of mold opening is increased, so that the pressed mold can be opened in multiple directions at the same time, reducing the difficulty of mold opening due to mold sticking.

[0027] The above-mentioned powder metallurgy mold with multi-directional mold opening has the advantages of simple structure and easy implementation, is suitable for installation and use in existing mold production, has low cost of use, and can improve efficiency.

[0028] In this embodiment, Figure 1-3 As shown, the transmission mechanism includes a first rack 410, a second rack 420 and a gear 430, the first rack 410 is vertically arranged at the bottom of the first side plate 200, the second rack 420 is vertically arranged at the bottom of the second side plate 300, the gear 430 is rotatably connected to the bottom surface of the transmission cavity, the first rack 410 extends into the transmission cavity from the first side portion, the second rack 420 extends into the transmission cavity from the second side portion, and the first rack 410 and the second rack 420 are respectively meshed with the lower and upper portions of the gear 430.

[0029] In this way, by setting the first rack 410, the second rack 420 and the gear 430, the first side plate 200 and the second side plate 300 can move simultaneously driven by the first rack 410 and the second rack 420, and the movement directions are opposite. At the same time, the first rack 410 and the second rack 420 only realize power transmission through one gear 430, and the power transmission structure is relatively simple and the reliability is good.

[0030] In this embodiment, Figure 1-3As shown, the transmission mechanism further includes a motor 440 , which is mounted on the outer bottom surface of the base plate 100 . The rotating shaft of the motor 440 extends into the transmission cavity and is transmission-connected to the gear 430 .

[0031] In this way, by setting up the motor 440, the gear 430 can be driven by the motor 440 to rotate without the need for an additional mechanical transmission structure. The motor 440 has a higher transmission efficiency and a lower cost.

[0032] During implementation, the rotating shaft of the motor 440 extends into the transmission cavity and is coaxially connected with the gear 430.

[0033] In this embodiment, Figure 1-3 As shown, it also includes a base 500, and the top surface of the base 500 is provided with a pressing groove 510 opening upward. The bottom plate 100 is arranged in the pressing groove 510 and can slide along the height direction of the pressing groove 510.

When the bottom plate 100 is located at the bottom of the pressing groove 510, the two side walls of the pressing groove 510 can provide a limiting force for die-casting, so as to improve the reliability and stability of the die-casting mold; when the bottom plate 100 slides upward and is located at the top of the pressing groove 510, the two sides of the bottom plate 100 are separated from the restrictions of the two side walls of the pressing groove 510, and can provide expansion space for the outside of the first side plate 200 and the second side plate 300, so as to better perform the mold opening process.

[0035] During implementation, there are two cylinders 520 , one on the left and one on the right, which are arranged in the base 500 , and the push rods of the two cylinders 520 are both extended into the pressing groove 510 and connected to the bottom of the base plate 100 .

[0036] During implementation, a placement groove is provided at the bottom of the pressing groove 510 , and the position of the placement groove corresponds to the motor 440 . When the bottom plate 100 moves toward the bottom of the pressing groove 510 , the motor 440 can enter the space of the placement groove.

[0038] In this way, by providing the first slide rail 530 and the second slide rail 540 , the first side plate 200 and the second side plate 300 can slide outward more smoothly and better with better guidance when the bottom plate 100 rises to the top of the pressing groove 510 .

[0039] In this embodiment, Figure 1-3 As shown, a plurality of pulleys are arranged on the bottom surfaces of the first slide rail 530 and the second slide rail 540 along the sliding direction.

[0040] In this way, the provided pulley can reduce the friction between the first side plate 200 and the second side plate 300 when sliding, making it easier to slide.

[0041] In this embodiment, Figure 4 As shown, the third side panel 610 and the fourth side panel 620 are also included, and the bottom panel 100 also includes a third side portion and a fourth side portion opposite to each other, the third side panel 610 is hinged on the third side portion, and the fourth side panel 620 is hinged on the fourth side portion, so that the first side panel 200, the second side panel 300, the third side panel 610 and the fourth side panel 620 are combined to form a rectangular trough body when they are erected together.
