[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 of 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] A metal injection molded joystick sintering jig is used to support a metal injection molded joystick 5 to prevent the joystick 5 from being deformed or broken during an actual MIM sintering process.

[0024] like Figure 1-4 As shown, the sintering jig includes a jig body 1, which is a rectangular frame structure, and side support plates 2 are installed on both sides of the jig body 1, and the side support plates 2 are fixedly connected to the two sides of the jig body 1. An arc surface is opened on the side support plate 2, and the arc surface is connected to the surface of the jig body 1 to form an integrated structure.

[0025] A symmetrically distributed jig plate 4 is installed on the jig body 1. The jig plate 4 is arranged parallel to the side of the jig body 1, and the jig plate 4 is fixedly connected to the side position of the jig body 1 close to the side support plate 2, which is used to separate the position of the jig body 1 and the side support plate 2. An array of grooves 41 are opened on the jig plate 4, and several grooves 41 are arranged on the jig plate 4 at equal intervals. The bottom surface of the groove 41 is connected to the arc surface to support the curved part of the joystick 5. The smooth transition ensures the sintering process. The joystick 5 fits on the arc surface to avoid warping and deformation of the curved part of the joystick 5, thereby reducing the operation of later correction.

[0026] A partition rod 3 is fixedly installed on the jig body 1, and sink grooves 13 are provided on both sides of the partition rod 3. The sink grooves 13 are symmetrically opened on the jig body 1 and are used for taking and placing the joystick 5. The jig body 1 is provided with symmetrically distributed product grooves 11. The two product grooves 11 are located on both sides of the partition rod 3 and are used to support the ends of the joystick 5. The height of the product grooves 11 is lower than the bottom surface of the groove 41, thereby ensuring the height between the end of the joystick 5 and the bent portion, ensuring the firmness of the bent portion of the joystick 5 during the sintering process, avoiding the breakage of the bent portion of the joystick 5, and ensuring the stable sintering of the joystick 5.

[0027] The product tank 11 can hold a plurality of joysticks 5 and simultaneously support a plurality of joysticks 5 for batch sintering operations.

[0028] In this embodiment, a groove 2 10 is provided at the bottom of the jig body 1, and the groove 2 10 reduces the weight of the jig body 1 and reduces the cost of the jig body 1. A reinforcing rib 12 is fixedly connected in the groove 2 10, and the reinforcing rib 12 supports the jig body 1 and maintains the shape of the jig body 1.

[0029] Here’s how it works:

[0030] In the metal injection molding process, the prepared joystick 5 is sent to the sintering process, a jig body 1 is taken, and the joystick 5 is arranged on the jig body 1 in an orderly manner. The end of each joystick 5 is placed on the product groove 11, and the bent part of the joystick 5 is located on the arc surface of the side support plate 2. After the joystick 5 is quickly placed, the jig body 1 can be placed in the sintering box to sinter the joystick 5.

[0031] The side support plate 2 stabilizes the joystick 5, and the end of the joystick 5 is clamped in the product groove 11. The curved surface of the joystick 5 is not easily deformed, ensuring that the joystick 5 product has the same curvature and will not warp or deform, ensuring that the product is reliably finalized during the sintering process and reducing complex correction steps in the later stage.
