Description

Technical Field

[0001] The utility model relates to the technical field of die casting, and particularly relates to a shot locking mechanism of a die casting machine. Background Art

[0002] A die casting machine is a machine used for die casting. Under pressure, it hydraulically injects molten metal into a mold for cooling and forming, and a solid metal casting can be obtained after the mold is opened. On the existing shot device of a die casting machine, in order to enable the shot nozzle to complete the shot action more stably, a shot locking mechanism is usually provided on the shot device, and the shot locking mechanism is used to lock the shot device at the moment of shooting.

[0003] For example, Chinese patent document CN214392277U discloses a shot device for a die casting equipment. The shot device includes a shot mechanism, a longitudinal pushing mechanism connected to the shot mechanism, and also includes a shot locking mechanism. The shot locking mechanism includes a servo electric cylinder and a joint assembly connected between the servo electric cylinder and the shot mounting seat. The joint assembly includes a connecting ear connected to the output shaft of the servo electric cylinder, a joint rotating shaft arranged on the connecting ear, and a linkage plate rotatably connected to the joint rotating shaft. The linkage plate is connected to the shot mounting seat. Since the shot locking mechanism adopts a structure of a thrust shaft structure (connecting ear) plus a rotating shaft (linkage plate), when performing the locking action, the servo electric cylinder pushes the connecting ear, the connecting ear pushes the linkage plate, and the linkage plate rotates to apply a force towards the mold direction to the shot mounting seat. Since the linkage plate makes a rotational movement in the front and rear directions, the shot nozzle on the shot mounting rotates in an arc around the rotation fulcrum of the linkage plate, and the contact mode between the shot nozzle and the mold is a circular arc surface contact. This easily causes friction between the shot nozzle and the mold, and a gap is generated between the shot nozzle and the mold, resulting in leakage of the shot during shooting. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a shot locking mechanism of a die casting machine, which can prevent friction and gap generation between the shot nozzle and the mold during the locking action, and avoid the occurrence of leakage.

[0005] To solve the above technical problem, the utility model adopts the following technical solutions:

[0006] A shot-locking mechanism for a die-casting machine, which is used to lock the shot device of the die-casting machine. The shot device is arranged on the back of a longitudinal mounting plate. The shot-locking mechanism includes a fixed component, a sliding component, a servo electric cylinder and a joint component; the fixed component includes two fixed side plates, which are respectively arranged in parallel and at intervals on both sides of the shot device. Guide grooves are provided on the inner side walls of the fixed side plates along the Y-axis direction; the sliding component includes two sliding side plates and two sliding shafts. The two sliding side plates are respectively arranged in parallel on both sides of the shot device and are fixedly connected to the shot device. Guide protrusions that are slidably connected to the guide grooves are provided on the outer side walls of the sliding side plates along the Y-axis direction. The two sliding shafts are respectively vertically fixed to the lower parts of the two sliding side plates and extend outwards through the fixed side plates; the servo electric cylinder is rotatably connected to the upper end of the longitudinal mounting plate; the joint component includes a connecting ear, a front and rear lever, a connecting rod and a front and rear rotating shaft. The connecting ear is connected to the output shaft of the servo electric cylinder. A joint rotating shaft is provided on the connecting ear. The front and rear levers and the connecting rod are respectively arranged in parallel on the outer sides of the two fixed side plates. The front and rear rotating shafts movably penetrate through the two fixed side plates and the two sliding side plates, and the two ends of the front and rear rotating shafts are respectively key-connected to the front and rear levers and the connecting rod. The upper end of the front and rear levers is rotatably connected to the joint rotating shaft. U-shaped buckles connected to the two sliding shafts are provided at the lower ends of the front and rear levers and the connecting rod.

[0007] In some embodiments, relief openings for the front and rear rotating shafts to pass through are provided on the two sliding side plates along the Y-axis direction.

[0008] Compared with the prior art, the present utility model at least achieves the following beneficial effects:

[0009] The shot-locking mechanism includes a fixed component, a sliding component, a servo electric cylinder and a joint component. When performing the locking action, the output shaft of the servo electric cylinder extends outwards, driving the connecting ear to push the upper end of the front and rear levers to rotate outwards. Since the two ends of the front and rear rotating shafts are respectively key-connected to the front and rear levers and the connecting rod, the front and rear levers rotate together with the connecting rod around the axis of the front and rear rotating shafts. At this time, the lower ends of the front and rear levers and the connecting rod both rotate towards the mold direction. The U-shaped buckles at the lower ends of the front and rear levers and the connecting rod push the sliding shafts, and the sliding shafts drive the sliding side plates to slide along the Y-axis direction on the inner side walls of the fixed side plates, thereby driving the shot nozzle to vertically move towards the mold direction, so that the shot nozzle is in a perpendicular straight-line contact with the mold, preventing the shot nozzle from rubbing against the mold and generating gaps, avoiding leakage of the nozzle, and maintaining the stability of production.

[0021] Such as Figures 1 to 7As shown, in one embodiment of the present utility model, the shot locking mechanism of the die-casting machine includes a fixed component 3, a sliding component 4, a servo electric cylinder 5 and a joint component 6; when the shot device 1 of the die-casting machine performs a shot action, the shot locking mechanism is used to lock the shot device 1. In this application, the shot device 1 is arranged on the back of a longitudinal mounting plate 2. The shot device 1 includes a gooseneck pot shot mechanism 11 and a longitudinal pushing mechanism 12. The longitudinal pushing mechanism 12 is connected above the gooseneck pot shot mechanism 11. The gooseneck pot shot mechanism 11 includes a shot nozzle 111, a melting furnace, a gooseneck pot and a shot plunger. The longitudinal pushing mechanism 12 includes a shot oil cylinder and a core shaft. The core shaft is inserted into the shot oil cylinder body and connected to the shot plunger of the gooseneck pot shot mechanism 11. The longitudinal pushing mechanism 12 is used to drive the gooseneck pot shot mechanism 11 to perform reciprocating actions of pushing down and pulling up, so that the liquid material is ejected through the shot nozzle 111; during shot, the shot nozzle 111 moves close to the longitudinal mounting plate 2, and the shot nozzle 111 penetrates to the front of the longitudinal mounting plate and is inserted into the mold.

[0022] Among them, the fixed component 3 includes two fixed side plates 31. The two fixed side plates 31 are respectively arranged on both sides of the gooseneck pot shot mechanism 11 in parallel and at intervals. A guide groove 311 is arranged on the inner side wall of the fixed side plate 31 along the Y-axis direction; the sliding component 4 includes two sliding side plates 41 and two sliding shafts 42. The two sliding side plates 41 are respectively arranged on both sides of the gooseneck pot shot mechanism 11 in parallel and fixedly connected to the gooseneck pot shot mechanism 11. A guide projection 411 that is slidably connected to the guide groove 311 is arranged on the outer side wall of the sliding side plate 41 along the Y-axis direction. The two sliding shafts 42 are respectively vertically fixed at the lower parts of the two sliding side plates 41, and the sliding shafts 42 penetrate outward through the fixed side plates 31; the servo electric cylinder 5 is rotatably connected to the upper end of the longitudinal mounting plate 2. Specifically, a fixed ear is arranged at the top of the longitudinal mounting plate 2. The servo electric cylinder 5 is electrically connected to the PLC controller of the die-casting machine. A front end plate is arranged at the front end of the cylinder body of the servo electric cylinder 5. Connecting rotating shafts for rotatably connecting with the fixed ears are arranged on both sides of the front end plate; the joint component 6 includes a connecting ear 61, a front and rear toggle rod 62, a connecting rod 63 and a front and rear rotating shaft 64. The connecting ear 61 is connected to the output shaft of the servo electric cylinder 5. A joint rotating shaft 611 is arranged on the connecting ear 61. The front and rear toggle rod 62 and the connecting rod 63 are respectively arranged outside the two fixed side plates 31 in parallel. The front and rear rotating shaft 64 movably penetrates through the two fixed side plates 31 and the two sliding side plates 41, and both ends of the front and rear rotating shaft 64 are respectively key-connected to the front and rear toggle rod 62 and the connecting rod 63. The upper end of the front and rear toggle rod 62 is rotatably connected to the joint rotating shaft 611. U-shaped bayonets 7 for connecting with the two sliding shafts 42 are arranged at the lower ends of the front and rear toggle rod 62 and the connecting rod 63.

[0023] Among them, the gooseneck pot shot mechanism 11 is fixedly connected between the lower parts of the two sliding side plates 41; the longitudinal pushing mechanism 12 is fixedly connected to the upper ends of the two sliding side plates 41.

[0024] The working principle of the shooting locking mechanism is as follows: while the shooting nozzle 111 is extended into the mold for shooting, the servo electric cylinder 5 drives the joint assembly 6 to work, and when the output shaft of the servo electric cylinder 5 is extended outward, it drives the connecting ear 61 to push the upper end of the front and rear lever 62 to rotate outward. Since the two ends of the front and rear rotating shafts 64 are respectively connected to the front and rear levers 62 and the connecting rod 63 by keys, the front and rear levers 62 rotate together with the connecting rod 63 around the axis of the front and rear rotating shafts 64. At this time, the lower ends of the front and rear levers 62 and the connecting rod 63 are both rotated in the direction close to the longitudinal mounting plate 2, and the U-shaped bayonet 7 at the lower ends of the front and rear levers 62 and the connecting rod 63 push the sliding shaft 42 inward, and the sliding shaft 42 drives the sliding side plate 41 to slide on the inner side wall of the fixed side plate 31 along the Y-axis direction, thereby driving the shooting nozzle 111 of the gooseneck pot shooting mechanism 11 to move vertically toward the mold direction, and then contact the mold to shoot. ; The existing shooting locking mechanism adopts a structure of a thrust shaft plus a rotating shaft. When the locking action is performed, the nozzle and the mold are in contact with an arc surface, which easily causes friction between the nozzle and the mold, resulting in leakage during shooting. The shooting locking mechanism of the present application is provided with a sliding component 4. When the locking action is performed, the movement trajectory of the shooting nozzle 111 is a linear motion perpendicular to the mounting plate 2, so that the shooting nozzle 111 is in vertical linear contact with the mold, avoiding friction and avoiding leakage due to a gap between the shooting nozzle 111 and the mold; on the contrary, after the shooting action is completed, the output shaft of the servo electric cylinder 5 contracts inwardly, and the shooting locking mechanism releases the locking action of the gooseneck pot shooting mechanism 11, and the lower end of the gooseneck pot shooting mechanism 11 moves away from the mold, and the shooting nozzle 111 can be withdrawn and pulled out; repeating the above steps can complete each locking and shooting action.

[0025] Optionally, the two sliding side plates 41 are provided with clearance openings 412 along the Y-axis direction for the front and rear rotating shafts 64 to pass through. When the sliding side plates 41 move forward and backward along the Y-axis direction, the clearance openings 412 can prevent the sliding side plates 41 from interfering with the front and rear rotating shafts 64.

[0026] Optionally, a first cross bar 8 is fixedly connected between the front ends of the two fixed side plates 31 ; and a second cross bar 9 is fixedly connected between the rear ends of the two sliding side plates 41 .

[0027] Optionally, a clamping ring 10 is provided at the protruding ends of the two sliding shafts 42 , and two sides of the clamping ring 10 are provided with a clamping groove that is clamped with the U-shaped bayonet 7 .

[0028] Optionally, the fixing component 3 further includes a first substrate 32, a second substrate 33 and two fixing plates 34; the first substrate 32 is arranged in parallel on the back surface of the longitudinal mounting plate 2, and first sliders 321 are arranged on both sides of the first substrate 32 along the Z-axis direction. The two fixing plates 34 are fixed on the longitudinal mounting plate 2 and are respectively located on both sides of the first substrate 32. First chutes 341 which are slidably connected with the first sliders 321 are arranged on the inner side walls of the fixing plates 34 along the Z-axis direction. The second substrate 33 is arranged in parallel on the first substrate 32, and second sliders 331 are arranged at the upper and lower ends of the second substrate 33 along the X-axis direction.

[0029] Furthermore, a die aligning mechanism 30 is arranged on the fixing component 3. The die aligning mechanism 30 includes an up-and-down displacement component 40 and a left-and-right displacement component 50; the up-and-down displacement component 40 includes a longitudinal servo motor 401, a longitudinal screw rod 402 and a longitudinal connecting rod 403.

The lead screw nut 60 is mounted on the fixed side plate 31.

[0030] After the injection device 1 is installed on the longitudinal mounting plate 2, the adjusted position information of the injection device 1 is automatically stored in the PLC controller of the die-casting machine. Whenever a new injection device 1 is replaced, the position information can be retrieved through the PLC controller, so as to control the up-and-down displacement assembly 40 and the left-and-right displacement assembly 50 of the die-set adjusting mechanism 30 to work, so as to adjust the position of the injection device 1; when the up-and-down displacement assembly 40 works, the longitudinal servo motor 401 drives the longitudinal screw 402 to rotate, and the longitudinal screw 402 drives the longitudinal connecting rod 403 to move longitudinally, thereby driving the first substrate 32 to move longitudinally. The first substrate 32 can drive the second substrate 33 and the two fixed side plates 31 to move longitudinally, so as to adjust the longitudinal position of the injection device 1; when the left-and-right displacement assembly 50 works, the transverse servo motor 501 drives the transverse connecting rod 502 to rotate, so that the lead screw nut 60 screwed to the transverse connecting rod 502 moves transversely. The lead screw nut 60 is installed on the fixed side plate 31, thereby driving the fixed side plate 31 and the second substrate 33 to move transversely, wherein the second substrate 33 moves transversely along the first substrate 32, so as to adjust the transverse position of the injection device 1. The die-set adjusting mechanism 30 can realize the automatic die-setting of the injection device 1.
