[0047] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application is further described in detail below in combination with the figures and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0048] ​It should be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element.

[0049] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0050] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0051] In actual application, the setting position of the die casting furnace needs to be determined according to the production site, and the pouring port direction on the furnace is also prone to change. The pouring direction of the ladle on the die casting equipment is fixed, and the driving arm on the die casting equipment can only drive the ladle to realize the pouring action of up and down swing. Both of them can only be matched with the pouring angle through position setting, so that the ladle can accurately pour the die casting material into the pouring port of the furnace when it swings down. It can be seen that the traditional die casting equipment makes it very difficult to set the production equipment on site, which is not conducive to practical application.

[0052] In order to adjust the horizontal rotation angle of the ladle, in the related art, the ladle and the driving arm adopt a disassembly and assembly structure, and a ring is additionally installed on the ladle, so that the ladle can be horizontally rotated to adjust the pouring angle. After the angle is adjusted, the ring is fixed on the connecting end of the driving arm, so as to realize the adjustment of the pouring angle.

[0053] However, the traditional hoop is an annular body with an opening, and the annular body can be closed by adding fasteners such as screws, etc., so as to tightly fix the surrounded object in the hoop. It can be seen that the fasteners on the hoop are fixed by penetrating the hoop, which weakens the structural strength of the hoop. Since the ladle works in a high temperature environment, the fixing strength of the hoop is affected, and the fixed part of the hoop in the high temperature environment is prone to deformation, which causes the tight structure to be loose and unstable, and there is a risk that the ladle will fall off and a safety hazard. In addition, the position of the fastener on the hoop is prone to cause a blind area, which is difficult to observe and operate, thereby affecting the disassembly and daily maintenance.

[0054] Herein, the embodiment of the present application provides a new pouring mechanism and a die casting equipment with the pouring mechanism, the connecting structure between the ladle and the driving arm is redesigned, the structure is simple, which is beneficial to disassembly and assembly operation, and facilitates adjustment of the pouring angle of the ladle, effectively solves the problem that the pouring mechanism of the traditional die casting equipment cannot adjust the pouring angle, and the present application will be described in detail.

[0055] Please refer to Figure 1 and Figure 2 , the die casting equipment has the pouring mechanism provided by the embodiment of the present application, and the pouring mechanism comprises a ladle 1, a bracket 2, a driving arm 3 and a rotary positioning assembly.

[0056] The ladle 1 is arranged on the bracket 2. In the embodiment, the bracket 2 is constructed as an obliquely arranged rectangular frame body, and corresponding components can be added on the frame body to achieve installation connection with the ladle 1 and the driving arm 3 at both ends of the frame body, respectively.

[0057] The driving arm 3 is used to drive the ladle 1, and a pull rod 31 is arranged on the driving arm 3. The pull rod 31 is in transmission connection with the ladle 1 through the bracket 2, so as to drive the ladle 1 to swing up and down, thereby realizing the pouring action to the furnace. In the embodiment, the driving arm 3 is vertically arranged, and a driver can be connected to the driving arm 3, so as to drive the pull rod 31 to move up and down, thereby driving the ladle 1 to swing up and down.

[0058] Please refer to Figure 2 , Figure 3 and Figure 4 , the rotary positioning assembly comprises a shaft sleeve 4, an open edge ring 5 and a pressing ring 6, and the shaft sleeve 4 is installed on the connecting end of the driving arm 3. In the embodiment, the shaft sleeve 4 is vertically arranged, and the pull rod 31 penetrates into the shaft sleeve 4 and then extends to the bracket 2 to be in transmission connection with the ladle 1. As Figure 3As shown, the upper end of the shaft sleeve 4 has a first outer convex ring 40, and a plurality of fixing holes (not shown) are arranged in the first outer convex ring 40 in a ring shape; correspondingly, the connecting end of the driving arm 3 also has a second outer convex ring 32 which is mounted and matched with the first outer convex ring 40, and the second outer convex ring 32 has a plurality of screw holes (not shown) which are matched with the fixing holes of the first outer convex ring 40 in position, so that fasteners such as screws are added to enable the two to be connected and fixed.

[0059] Please refer to Figure 3 and Figure 4 , the outer periphery of the shaft sleeve 4 is provided with a buckle groove 41, which can be preferably arranged close to the lower end of the shaft sleeve 4 to be mounted and connected with the open edge ring 5.

[0060] The open edge ring 5 is provided with a buckle connecting portion 51 for buckling with the above-mentioned buckle groove 41, and the open edge ring 5 includes at least two arc-shaped segments 52 which are spliced together on the outer periphery of the shaft sleeve 4 to form a complete open edge ring 5.

[0061] Please refer to Figure 5 , Figure 6 and Figure 7 , the pressing ring 6 is detachably arranged on the connecting end of the support 2, and can be arranged on the connecting end of the support 2 by adding fasteners. As shown in Figure 5 , the pressing ring 6 has a receiving groove 61 which is matched with the shape of the open edge ring 5, so that the open edge ring 5 can be embedded in the receiving groove 61, thereby enabling the pressing ring 6 to limit the open edge ring 5 on the shaft sleeve 4 through the receiving groove 61. In this way, the driving arm 3 and the support 2 are connected to each other by the buckling of the shaft sleeve 4 and the open edge ring 5, and then the relative rotation of the pressing ring 6 and the open edge ring 5 is used to adjust the horizontal rotation angle of the spoon 1. After adjustment, the pressing ring 6 is fixed on the connecting end of the support 2 to lock the adjustment angle.

[0062] The pouring mechanism provided by the embodiment of the present application has the following advantages compared with the prior art. The rotating positioning assembly is arranged between the connecting end of the driving arm 3 and the connecting end of the support 2 of the spoon 1, and the rotating positioning assembly includes a shaft sleeve 4, an open edge ring 5 and a pressing ring 6. The shaft sleeve 4 is fixed on the connecting end of the driving arm 3, and the pressing ring 6 is arranged on the connecting end of the support 2. The outer periphery of the shaft sleeve 4 is provided with a buckle groove 41, and the open edge ring 5 is arranged on the outer periphery of the shaft sleeve 4 by splicing, so that the buckle connecting portion 51 of the open edge ring 5 and the buckle groove 41 of the shaft sleeve 4 are buckled with each other. Then, the open edge ring 5 is limited on the outer periphery of the shaft sleeve 4 by the receiving groove 61 of the pressing ring 6.

[0063] In this way, the buckle part 51 on the open edge ring 5 and the buckle groove 41 on the shaft sleeve 4 are buckled with each other, realizing the connection and fixation between the driving arm 3 and the support 2, so that the spoon 1 is hung on the lower end of the driving arm 3 through the support 2. In addition, the relative rotation of the compression ring 6 and the open edge ring 5 realizes the stepless adjustment of the horizontal rotation angle of the spoon 1, and after the angle is adjusted, the compression ring 6 is fixed on the connecting end of the support 2, so as to lock the adjusted angle.

[0064] Compared with the structure in the above-mentioned related art that sets a ring on the spoon 1 for rotation positioning, the pouring mechanism of the embodiment of the present application, on the one hand, the buckle part 51 of the shaft sleeve 4 and the open edge ring 5 is substantially the key part for connecting the driving arm 3 and the support 2, and the buckle part 51 of the shaft sleeve 4 and the open edge ring 5 are both accommodated in the inside of the compression ring 6, which is covered and protected by the compression ring 6, which is conducive to reducing the heating temperature in a high-temperature environment, and the structure of the buckle groove 41 on the shaft sleeve 4 and the buckle part 51 on the open edge ring 5 is stable and not easy to deform, effectively maintaining the fixed strength of mutual buckling, and further prolonging the service life. On the other hand, the structure of the compression ring 6 installed on the connecting end of the support 2 is a structure for locking after adjusting the horizontal rotation angle of the spoon 1, and the installation structure on the compression ring 6 is set in an open manner, which does not have a visual blind area, and is conducive to disassembly and assembly operations, and is convenient for production and installation, angle adjustment and daily maintenance.

[0065] Regarding the structure of the open edge ring 5, in one embodiment of the present application, please refer to Figure 8 The arc-shaped section 52 of the open edge ring 5 is preferably a semicircular section 52a, and the open edge ring 5 is formed by two semicircular sections 52a spliced with each other, and each semicircular section 52a has a buckle part 51.

[0066] In this way, the combined structure of the open edge ring 5 becomes simpler, which is conducive to reducing the number of combined parts. The two semicircular sections 52a are spliced with each other on the outer periphery of the shaft sleeve 4, and then the compression ring 6 is installed, so that the connection and fixation between the driving arm 3 and the support 2 can be quickly completed, effectively simplifying the installation operation and improving the assembly efficiency.

[0067] In other embodiments, the open edge ring 5 can also be preferably formed by three or four arc-shaped sections 52, thereby forming a complete ring body, and each arc-shaped section 52 has the buckle part 51, so that each arc-shaped section 52 can be buckled with the buckle groove 41 on the outer periphery of the shaft sleeve 4, thereby effectively ensuring the connection strength.

[0068] Regarding the matching structure between the buckle groove 41 on the shaft sleeve 4 and the buckle part 51 on the open edge ring 5, it includes but is not limited to the following forms:

[0069] In one embodiment of the present application, please refer to Figure 4 and Figure 8The buckle slot 41 on the shaft sleeve 4 is preferably an annular slot 41a around the outer periphery of the shaft sleeve 4, and the buckle part 51 on the open-end ring 5 is preferably an inner protruding ring 51a for buckling into the annular slot 41a.

[0070] In the present embodiment, each of the two semicircular segments 52a has a half of the inner protruding ring 51a, and when the two semicircular segments 52a are spliced together on the outer periphery of the shaft sleeve 4, they can buckle into the annular slot 41a of the shaft sleeve 4, effectively ensuring the stability of the connection between the open-end ring 5 and the shaft sleeve 4.

[0071] The inner protruding ring 51a on the open-end ring 5 can be preferably arranged near any one of the end openings of the open-end ring 5. In the present embodiment, as shown in Figure 8 , the inner protruding ring 51a is arranged on the upper end opening of the open-end ring 5, so that when the open-end ring 5 is buckled into the lower half of the shaft sleeve 4, the lower end opening of the open-end ring 5 can be flush with the lower end opening of the shaft sleeve 4.

[0072] In other embodiments, the inner protruding ring 51a on the open-end ring 5 can also be arranged centrally on the inner wall of the open-end ring 5, where "centrally arranged" refers to the central position in the height direction of the inner wall.

[0073] In this way, the open-end ring 5 can be arranged according to the size of the shaft sleeve 4 and the open-end ring 5, so that when the open-end ring 5 is buckled into the lower half of the shaft sleeve 4, the lower end opening of the open-end ring 5 can be flush with the lower end opening of the shaft sleeve 4.

[0074] In another embodiment of the present application (not shown), the buckle slot 41 on the shaft sleeve 4 is preferably a plurality of clamping slots (not shown) arranged annularly and uniformly on the outer periphery of the shaft sleeve 4. Correspondingly, the buckle part 51 on the open-end ring 5 is preferably a plurality of buckle blocks (not shown) for buckling into the clamping slots, and the number of buckle blocks is preferably the same as the number of clamping slots.

[0075] In this way, during installation, each buckle block can correspond to each buckle slot 41 and be buckled together, effectively ensuring the stability of the connection between the open-end ring 5 and the shaft sleeve 4.

[0076] In addition, compared with the first embodiment described above, in the present embodiment, due to the buckling of each buckle slot 41 and each buckle block, the open-end ring 5 and the shaft sleeve 4 can be prevented from rotating relative to each other when the angle of the compression ring 6 is adjusted, thereby affecting the adjustment effect.

[0077] As for the structure of the compression ring 6, in one embodiment of the present application, please refer to Figure 9The ring body of the compression ring 6 is further provided with a scale mark 62, which is used as a rotation angle reference. In this way, the operator can accurately adjust the required angle according to the scale mark 62, effectively improving the adjustment accuracy of the pouring angle of the spoon 1.

[0078] For the structure of the bracket 2, in one embodiment of the present application, please refer to Figure 5 , Figure 9 and Figure 10 The connecting end of the bracket 2 has a connecting table 21, and the connecting table 21 has a mounting hole 211 for mounting the compression ring 6. The compression ring 6 is provided with a connecting hole 63 corresponding to the position of the mounting hole 211, so that a fastener such as a screw is inserted and fixed.

[0079] In this embodiment, four mounting holes 211 are provided on the connecting table 21, which are evenly distributed on the connecting table 21. Correspondingly, the compression ring 6 is provided with connecting holes 63 which are the same in number as the mounting holes 211, and each connecting hole 63 penetrates the ring body of the compression ring 6. In actual operation, after adjusting the horizontal rotation angle by using the compression ring 6, the connecting holes 63 on the compression ring 6 are corresponded to the mounting holes 211 on the connecting table 21 one by one, and then a fastener such as a screw is inserted and fixed one by one, so as to lock the adjusted angle.

[0080] In this way, the fixing structure between the compression ring 6 and the connecting end of the bracket 2 is very simple and easy to implement, and adopts an open design, which has no visual blind area and is convenient for observation or operation. In addition, it is beneficial to use in high temperature environment, effectively ensures the fixing strength and prolongs the service life.

[0081] For the structure of the bracket 2, in another embodiment of the present application, please refer to Figure 7 , Figure 9 and Figure 10 The connecting table 21 is further provided with a through hole 212 and a guide sleeve 7 arranged on the through hole 212, and the pull rod 31 extends into the bracket 2 through the shaft sleeve 4 and the guide sleeve 7 in sequence and is connected with the spoon 1 through the transmission assembly.

[0082] In this embodiment, the guide sleeve 7 can be preferably made of metal material, and can be preferably made of copper material. The guide sleeve 7 has a guiding effect and wear resistance. The outer periphery of the guide sleeve 7 has a third outward protruding ring 71, so that the guide sleeve 7 can be inserted into the through hole 212 of the connecting table 21 from above, and the third outward protruding ring 71 is placed on the connecting table 21, and the lower end of the guide sleeve 7 extends from the bottom of the connecting table 21. After the pull rod 31 extends from the guide sleeve 7, it is convenient to be movably connected with the spoon 1 through the transmission assembly.

[0083] Therefore, the guiding effect and wear resistance of the guide sleeve 7 can improve the smoothness of the movement of the spoon 1 driven by the pull rod 31.

[0084] Please refer to Figure 11 and Figure 12 The transmission assembly includes a connecting rod 22 and a swing rod 23, and two ends of the connecting rod 22 are connected with the pull rod 31 and one end of the swing rod 23 through rotating shafts, respectively. The other end of the swing rod 23 is fixed on the spoon 1 and connected with the support 2 through a rotating shaft.

[0085] Therefore, the pull rod 31 drives the connecting rod 22 and the swing rod 23 to drive the spoon 1 to swing up and down during the up and down movement of the pull rod 31.

[0086] In another embodiment of the present application, please refer to Figure 13 , Figure 14 and Figure 15 The present application also provides a die casting equipment, which includes a column 8 and a cross beam 9 arranged on the column 8, and the cross beam 9 is provided with a moving device 91, a guide rail 92 and the pouring mechanism provided by the present application.

[0087] As shown in Figure 14 , the column 8 is provided with a control electric box 81, and the upper end of the column 8 is connected with the cross beam 9, which is supported by the column 8 at a set height.

[0088] Preferably, a height adjusting assembly 82 can be arranged on the connecting part of the column 8 and the cross beam 9, which can preferably adopt a common telescopic structure to adjust the height of the cross beam 9.

[0089] As shown in Figure 13 and Figure 15 , the moving device 91 is arranged on the guide rail 92, and the moving device 91 is provided with a motor to control the movement of the moving device 91 along the length direction of the guide rail 92.
