[0001] The utility model relates to the technical field of automatic material shifting for die casting, in particular to an automatic material shifting mechanism for gasket die casting. Background Art

[0002] Gasket is a mechanical seal between two objects, usually used to prevent leakage due to pressure, corrosion, and natural thermal expansion and contraction of the pipeline. Since the machined surface cannot be perfect, the use of gaskets can fill the irregularities. Gaskets are usually made of sheet materials such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic polymers (such as polytetrafluoroethylene). Gaskets for specific applications may contain asbestos.

[0003] In the process of producing gaskets, workers usually die-cast the gasket into multiple gaskets of the same specifications. When die-casting gaskets, there is a lack of equipment for automatic material selection and the waste generated cannot be processed in time on the processing table, which affects the quality of die-casting. A solution is proposed below to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] This embodiment provides a gasket die-casting automatic material feeding mechanism. Figures 1 to 4As shown, it includes: a processing table 1, a first toggle mechanism 3, a second toggle mechanism 4, a hydraulic cylinder 5 and a die-casting machine 6; a processing seat 2 coaxial with the die-casting machine 6 is also installed on the processing table 1; the die-casting machine 6 is arranged on the processing table 1, and is used to die-cast the pad transmitted on the processing seat 2 to form a gasket. Before processing, the end face of the processing seat 2 is adjusted to be flush with the first toggle mechanism 3 and the second toggle mechanism 4, so that the first toggle mechanism 3 and the second toggle mechanism 4 contact each other when alternately toggling the end face of the processing seat 2; the first toggle mechanism 3 is installed on one side of the processing table 1, and is used to toggle the die-cast gasket; the second toggle mechanism 4 is installed on the other side of the processing table 1, and is used to toggle the waste generated during the die-casting process; the cutter head of the die-casting machine 6 is conical, and abuts against the first toggle mechanism 3, and the hydraulic cylinder 5 is connected to the die-casting machine 6.

[0025] Based on the above basic mechanism, the first toggle mechanism 3 includes a first tension spring 7, a shaping strip 8, a paddle 9 and a lever 10. The lever 10 is installed on the processing table 1 and is located on the right side of the processing seat 2. The paddle 9 is installed on the end of the lever 10 close to the die-casting machine 6. The shaping strip 8 is wrapped around the end of the paddle 9 close to the lever 10, and one end of the tension spring is connected to the shaping strip 8.

[0026] The paddle 9 is made of elastic material, and the end of the paddle 9 close to the die-casting machine 6 is in the shape of a barb, which is convenient for moving the gasket die-cast on the end face of the processing seat 2. The first tension spring 7 and the shaping strip 8 play a protective role when the paddle 9 is squeezed, extending the service life of the paddle 9 and preventing the paddle 9 from rebounding too far. When the die-casting machine 6 is pressed downward with the hydraulic cylinder 5, the cross-section of the cutter head of the die-casting machine 6 is larger at the top and smaller at the bottom. The cutter head of the die-casting machine 6 squeezes the paddle 9 to one side, and when the die-casting machine 6 is lifted upward after the die-casting is completed, the paddle 9 will automatically rebound and return to its original state, so that the paddle 9 automatically moves the gasket out of the end face of the processing seat 2.

[0027] Based on the above basic mechanism, the second toggle mechanism 4 includes a rotating part 12, a toggle part 13 and a transmission part 11; the rotating part 12 is installed on the processing table 1 and is located on the left side of the processing seat 2, and is used to drive the resetting part to deflect; the toggle part 13 is installed on the rotating part 12, and is used to toggle the waste on the processing seat 2; the transmission part 11 is installed on the rotating part 12, and is used to drive the rotating part 12 to deflect and reset.

[0028] Based on the above basic mechanism, the rotating part 12 includes a linkage rod 14 and a linkage sleeve 15. The linkage rod 14 is rotatably arranged on the processing table 1. There are multiple linkage sleeves 15, and multiple linkage sleeves 15 are arranged on the linkage rod 14. The linkage rod 14 and the linkage sleeve 15 are fixed.

[0029] Based on the above basic mechanism, the toggle part 13 includes a toggle plate 16 and a screw rod 17 . The screw rod 17 passes through the linkage rod 14 and is threadedly engaged with the linkage rod 14 . One end of the screw rod 17 away from the linkage rod 14 is connected to the toggle plate 16 .

[0030] Based on the above basic mechanism, the transmission part 11 includes a connecting roller 18, a bending rod 19, a reset rod 20 and a second tension spring 21; the connecting roller 18 is installed on the linkage sleeve 15, the bending rod 19 is connected to the die-casting machine 6 and the bending rod 19 and the connecting roller 18 abut against each other, the reset rod 20 is installed on the linkage sleeve 15, and the two ends of the second tension spring 21 are respectively connected to the reset rod 20 and the die-casting machine 6.

[0031] Based on the above basic mechanism, the connecting roller 18 and the reset rod 20 both rotate along the axis of the linkage rod 14 .

[0032] Based on the above basic mechanism, the relative height of the first dial mechanism 3 is higher than the relative height of the second dial mechanism 4 .

[0033] The linkage sleeve 15 is divided into an upper sleeve, a middle sleeve and a lower sleeve. The screw 17 passes through the lower sleeve and is locked by thread. The toggle plate 16 is welded to the screw 17; the middle sleeve and the connecting roller 18 are fixed, and the upper sleeve and the reset rod 20 are threadedly matched. During the process of the hydraulic cylinder 5 driving the die-casting machine 6 to descend, the bending rod 19 fixed on the die-casting machine 6 will drive the connecting roller 18 to deflect counterclockwise around the axis of the linkage rod 14, and the reset rod 20 and the toggle plate 16 will rotate counterclockwise around the linkage rod 14 together. The second tension spring 21 on the reset rod 20 is in a stretched state, and the toggle plate 16 is away from the end face of the processing seat 2; when the hydraulic cylinder 5 drives the die-casting machine 6 to lift, the force of the bending rod 19 against the connecting roller 18 is reduced, and the second tension spring 21 will pull the reset rod 20 to reset itself, and the reset rod 20 rotates clockwise along the axis of the linkage rod 14, and the toggle plate 16 automatically removes the waste generated on the end face of the processing seat 2.

[0034] After the hydraulic cylinder 5 is turned on, the die-casting machine 6 die-casts the gasket on the processing seat 2. After each gasket is die-cast, the die-casting machine 6 is lifted up with the hydraulic cylinder 5, and the first toggle mechanism 3 automatically pushes the gasket out of the processing table 1, and the second toggle mechanism 4 automatically pushes the waste away from the end surface of the processing seat 2. The first toggle mechanism 3 and the second toggle mechanism 4 push in opposite directions, and the removed waste and gaskets are output separately on both sides to avoid waste mixing into the die-cast gaskets, thereby ensuring the quality of the die-cast gaskets and reducing the manual process of pushing the gaskets and cleaning the waste.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
