[0002] Metal Injection Molding (MIM) is a manufacturing method that combines traditional injection molding and metal powder metallurgy processes. It is widely used in the production of metal parts that require complex geometries, high precision, and small parts.

[0003] Currently, in the existing technology, some parts with nuts are injection molded to facilitate the installation of the parts. The nuts need to be manually placed into the mold one by one using tools. The nuts are small, and it is difficult for employees to place the nuts into the mold. Moreover, placing the nuts manually is prone to safety accidents. Therefore, a feeding device is needed to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a feeding device for tray nuts, which has the advantages of facilitating the feeding of nuts and reducing safety accidents.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A feeding device for tray nuts, including a mounting frame installed on the top of a mold machine table. A linear driving component one and a linear driving component two (3) are installed on the mounting frame. The linear driving component two is slidably installed on the mounting frame through the linear driving component one. A lifting component is slidably installed on the linear driving component two. It is characterized in that a side posture cylinder is installed at the output end of the lifting component, a feeding fixture is installed at the output end of the side posture cylinder, and a tray fixture installed on a tray device is arranged below the feeding fixture.

[0007] The advantages of this solution are at least as follows: When feeding nuts is required, by starting the linear driving component one and the linear driving component two, the lifting component is moved directly above the tray fixture. Then, the lifting component is started, and the feeding fixture is moved down to the tray fixture to pick up the nuts from the tray fixture. The lifting component is started again to raise the feeding fixture. The side posture cylinder is started to adjust the direction of the feeding fixture. The feeding fixture is moved into the mold machine table through the linear driving component one, the linear driving component two, and the lifting component, and the nuts are placed into the mold, avoiding the need for manual placement of nuts into the mold by workers and reducing the occurrence of safety accidents.

[0008] The utility model is further configured as follows: the loading fixture includes: a loading plate, a plurality of nut clamps are installed on the loading plate, a threaded hole is opened on the side wall of the nut clamp, the threaded hole passes through the nut clamp, a nut column is installed in the threaded hole, two cylinders are installed on the loading plate through a plurality of support columns, the cylinder is installed with a horizontal plate, the horizontal plate is fixedly connected to the output end of the side cylinder, the output ends of the two cylinders are both installed with a blanking plate, a plurality of blanking rods are fixedly installed on the blanking plate, and the blanking rods extend into the nut clamp.

[0009] The advantage of this solution is at least that when the loading fixture fixes the nut, it only needs to put the nut clamp on the outer wall of the nut, and the nut column will fix the nut in the nut clamp under the action of the nut column, so as to avoid the nut falling during the upward movement.

[0010] The utility model is further configured as follows: the nut column is configured to be hollow inside, a spring is coaxially installed inside the hollow nut column, a fixing ball is installed at the end of the spring, a limiting hole with a diameter smaller than the diameter of the fixing ball is provided at one end of the nut column, and the fixing ball is squeezed by the spring and partially protrudes out of the limiting hole.

[0011] The advantage of this scheme is at least that when placing the nut into the mold on the mold machine, it is only necessary to start the two cylinders. The cylinders push the blanking plate to move the blanking rod. During the movement of the blanking rod, the fixed ball is squeezed, the fixed ball squeezes the spring, and squeezes the fixed ball into the nut column, thereby releasing the fixation of the nut by the nut column, and pushing the nut from the nut clamp into the mold of the mold machine.

[0012] The utility model is further configured as follows: a thread is provided at one end of the nut clamp away from the threaded hole, a fixing nut 1 is threadedly connected to the thread, and the nut clamp is detachably mounted on the loading plate through the fixing nut 1 and the thread.

[0014] The utility model is further configured as follows: one end of the nut column away from the fixing ball is recessed inwardly to form an inner hexagonal groove.

[0015] The advantages of this solution are at least that the depth of the nut column in the threaded hole can be adjusted by a hexagonal screwdriver, thereby reducing the size of the threaded column exposed to the outside and reducing interference with other parts.

[0016] The utility model is further configured as follows: a guide column is provided on the loading plate, a guide cylinder is provided on the swing plate clamp, and an end portion of the guide column is provided with an oblique angle.

[0017] The advantages of this solution are at least as follows: The provision of the guide posts and guide cylinders plays a guiding role for the loading fixture when the loading fixture grabs the nuts on the tray fixture, facilitating the alignment of the nut clamping cylinder with the nuts on the tray fixture. The chamfer at the end of the guide post facilitates the easier entry of the guide post into the guide cylinder.

[0018] The present utility model is further configured such that: An inductive switch is also threadedly connected within the threaded hole.

[0019] The advantages of this solution are at least as follows: The provision of the inductive switch facilitates the confirmation of whether the nut clamping cylinder has grabbed the nuts from the tray fixture.

[0020] The present utility model is further configured such that: A fixing nut II is threadedly connected between the inductive switch and the outer wall of the nut column.

[0021] The advantages of this solution are at least as follows: The provision of the fixing nut II strengthens the connection between the inductive switch and the nut column and the threaded hole, avoiding the phenomenon of dropping during use.

[0022] In summary, the present utility model has at least the following advantages:

[0023] 1. By providing the side posture cylinder, the loading fixture, and the tray fixture, when nuts need to be loaded, by starting the first linear drive assembly and the second linear drive assembly, the lifting assembly is moved directly above the tray fixture, then the lifting assembly is started, the loading fixture is lowered onto the tray fixture, the nuts are grabbed from the tray fixture, the lifting assembly is started again to raise the loading fixture, the side posture cylinder is started to adjust the direction of the loading fixture, and the loading fixture is moved into the die machine table through the first linear drive assembly, the second linear drive assembly, and the lifting assembly, and the nuts are placed into the die, avoiding the need for manual placement of the nuts into the die by workers and reducing the occurrence of safety accidents;

[0024] 2. By providing the nut column and having a spring and a fixing ball inside the nut column, when the loading fixture fixes the nuts, only the nut clamping cylinder needs to be sleeved on the outer wall of the nut and is fixed in the nut clamping cylinder by the nut column under the action of the nut column, avoiding the phenomenon of dropping of the nuts during the upward movement. When the nuts are placed into the die on the die machine table, only two cylinders need to be started. The cylinders push the blanking plate to move, causing the blanking rod to move. During the movement of the blanking rod, since the fixing ball is squeezed, the fixing ball squeezes the spring and is squeezed into the nut column, thereby releasing the fixation of the nut column on the nut, and the nuts are pushed from the nut clamping cylinder into the die on the die machine table;

[0025] 3. By setting the fixing nut one and the thread, when one of the nut clamps cannot be used, it is convenient to disassemble, replace and repair the nut clamp. By setting the inward depression to form an inner hexagonal groove, the depth of the nut column in the threaded hole can be adjusted by a hexagonal screwdriver, reducing the size of the nut column exposed to the outside and reducing interference with other parts. The setting of the induction switch is convenient for confirming whether the nut clamp has clamped the nut from the swing plate clamp. The setting of the fixing nut two strengthens the connection between the induction switch and the nut column and the threaded hole to avoid falling during use. BRIEF DESCRIPTION OF THE DRAWINGS

They all belong to the prior art and will not be elaborated here.

[0034] As Figure 2 , Figure 3 , Figure 4 As shown in the figure, in some embodiments, the feeding fixture 6 includes: a feeding tray 601. A number of nut holders 602 are installed on the feeding tray 601. A threaded hole 603 is provided on the side wall of the nut holder 602. The threaded hole 603 runs through the nut holder 602. A nut column 604 is installed in the threaded hole 603. An inductive switch 15 is also threadedly connected in the threaded hole 603. In some preferred embodiments, in order to strengthen the connection between the inductive switch 15 and the nut column 604 and the threaded hole 603, a fixing nut two 16 is threadedly connected to the outer walls of the inductive switch 15 and the nut column 604, so as to avoid the phenomenon of falling off during use. In some preferred embodiments, in order to facilitate the alignment of the nut holder 602 with the nuts on the tray fixture 7, a guide post 13 is provided on the feeding tray 601, and a guide cylinder 14 is provided on the tray fixture 7. The end of the guide post 13 is provided with an oblique angle.

[0035] It is worth mentioning that the nut column 604 is hollow inside. A spring 8 is coaxially installed inside the hollow nut column 604. A fixed ball 9 is installed at the end of the spring 8. A limiting hole 10 with a diameter smaller than the diameter of the fixed ball 9 is provided at one end of the nut column 604. The fixed ball 9 is extruded by the spring 8 and partially protrudes from the limiting hole 10.

[0036] As Figure 2 , Figure 3 , Figure 4 As shown in the figure, in some embodiments, in order to facilitate the placement of the nuts into the mold, two cylinders 605 are installed on the feeding tray 601 through a number of support columns. The cylinders 605 are installed on a cross plate 606. The cross plate 606 is fixedly connected to the output end of the side posture cylinder 5. The output ends of the two cylinders 605 are both installed with a blanking plate 607. The blanking plate 607 is slidably installed on the outer wall of the support column.

The nut holder 602 is detachably mounted on the loading tray 601 through the first fixing nut 11 and the thread. It is worth mentioning that an inner hexagonal groove 12 is formed by inward depression at one end of the nut post 604 away from the fixed ball 9.

[0038] The working process and beneficial effects of the present utility model are as follows:

[0039] When it is necessary to load nuts, by starting the first linear drive assembly 2 and the second linear drive assembly 3, the lifting assembly 4 is moved directly above the placing plate fixture 7, and then the lifting assembly 4 is started to lower the loading fixture 6 onto the placing plate fixture 7. When the loading fixture 6 fixes the nut, only the nut holder 602 needs to be sleeved on the outer wall of the nut, and under the action of the nut post 604, the nut is fixed in the nut holder 602 by the nut post 604, avoiding the phenomenon of the nut falling during the upward movement.

[0040] The nut is picked up from the placing plate fixture 7, the lifting assembly 4 is started again to raise the loading fixture 6, the side posture cylinder 5 is started to adjust the direction of the loading fixture 6, and the loading fixture 6 is moved into the mold machine table through the first linear drive assembly 2, the second linear drive assembly 3 and the lifting assembly 4. When the nut is placed into the mold on the mold machine table, only the two cylinders 605 need to be started. The cylinders 605 push the blanking plate 607 to move, causing the blanking rod 608 to move. During the movement of the blanking rod 608, since the fixed ball 9 is squeezed, the fixed ball 9 squeezes the spring 8 and is squeezed into the nut post 604, thereby releasing the fixation of the nut by the nut post 604, and the nut is pushed from the nut holder 602 into the mold on the mold machine table, avoiding the need for manual placement of the nut into the mold by workers and reducing the occurrence of safety accidents.

[0041] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
