[0051] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0052] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0053] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0054] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0055] This embodiment provides a slide mechanism 10 and a die-casting machine. The die-casting machine, when in operation, can cooperate with a die-casting mold to perform die-casting operations. For ease of explanation, this embodiment defines three mutually perpendicular directions within a space as a first direction, a second direction, and a third direction. The first direction is represented by the letter X, the second direction by the letter Y, and the third direction by the letter Z.

[0056] like Figures 2 to 5 As shown, the die-casting machine includes a support assembly 20, an ejection drive assembly 30, a top plate 50, a force transmission rod assembly 40 and a slide mechanism 10. Among them, the support assembly 20 is a fixed structure, and can support other components. The support assembly 20 is roughly located in the XZ plane. The ejection drive assembly 30 is mounted on the support assembly 20, and can output linear motion along the second direction (i.e., the Y direction). Optionally, the ejection drive assembly 30 is an oil cylinder. The top plate 50 is connected to the output end of the ejection drive assembly 30, and the force transmission rod assembly 40 connects the top plate 50 and the slide mechanism 10. The slide mechanism 10 is used to connect to the movable mold of the die-casting mold, so that the ejection drive assembly 30 can drive the movable mold to reciprocate along the second direction. Specifically, as Figure 4 As shown, the ejector drive assembly 30 and the ejector plate 50 are arranged on one side of the support assembly 20, the force transmission rod assembly 40 passes through the support assembly 20 and extends to the other side of the support assembly 20, and the slide mechanism 10 is located on the other side of the support assembly 20. The movable mold (not shown) of the die-casting mold is located on the side of the slide mechanism 10 away from the support assembly 20. The ejector drive assembly 30 can drive the slide mechanism 10 to approach the movable mold along the second direction, thereby realizing the cooperation between the movable mold and the slide mechanism 10. Figure 5 As shown, the movable mold of the die-casting mold includes a push rod 100, and the push rod 100 is used to cooperate with the slide mechanism 10 to achieve the cooperation between the movable mold and the die-casting machine. Specifically, the slide mechanism 10 includes a mounting base 1 and a slide 2. The mounting base 1 and the slide 2 are arranged in close contact and are both arranged parallel to the XZ plane. The slide 2 is arranged on the side of the mounting base 1 facing the support assembly 20. The mounting base 1 is connected to the force transmission rod assembly 40. The slide 2 can move in a first direction relative to the mounting base 1. A matching portion 25 is provided on the slide 2. A fourth avoidance hole 13 is provided on the mounting base 1 at a position corresponding to the card slot. When the slide 2 moves in the first direction, it can achieve cooperation with the push rod 100 of the movable mold. Specifically, combined with Figure 5 and Figure 12 A card groove is provided on the circumferential surface of the push rod 100, and the matching portion 25 is constructed as a groove structure. When the push rod 100 passes through the fourth avoidance hole 13 and the matching portion 25 in sequence, and the card groove on the push rod 100 and the groove structure are engaged with each other, the push rod 100 is matched with the skateboard 2.

[0057] like Figure 2 、 Figure 5 and Figure 12 As shown, the actions of the die-casting machine and the movable mold of the die-casting mold to achieve cooperation are roughly as follows: the ejection drive assembly 30 drives the slide mechanism 10 along the second direction (i.e., the Y direction) to approach the movable mold of the die-casting mold; at this time, the ejector rod 100 on the movable mold sequentially passes through the fourth avoidance hole 13 and the matching portion 25 along the second direction, and the card slot on the ejector rod 100 is arranged opposite to the matching portion 25; then the slide plate 2 moves along the first direction relative to the mounting base plate 1, and the matching portion 25 is engaged with the card slot. At this time, the cooperation between the slide mechanism 10 and the movable mold of the die-casting mold is achieved.

[0058] like Figures 5 to 7 As shown, the slide mechanism 10 further includes a double-acting hydraulic cylinder 3, which is used to drive the slide 2 to reciprocate in a first direction relative to the mounting base 1. Preferably, a mounting hole 21 is provided on the slide 2. The double-acting hydraulic cylinder 3 includes a cylinder assembly 31 and a piston rod 32. The cylinder assembly 31 is connected to the mounting base 1 and disposed within the mounting hole 21. The piston rod 32 extends in the first direction and penetrates the cylinder assembly 31. Both ends of the piston rod 32 respectively abut against the wall of the mounting hole 21. The piston rod 32 is capable of reciprocating in the first direction relative to the cylinder assembly 31, thereby driving the slide 2 to reciprocate in the first direction relative to the mounting base 1.

[0059] The slide mechanism 10 of this embodiment, by installing the double-acting hydraulic cylinder 3 within the mounting hole 21 of the slide 2, integrates the components driving the slide within the coverage of the slide 2, thereby greatly reducing the size of the slide mechanism 10 and enabling the slide mechanism 10 to be applied in scenarios where space is limited. The two ends of the piston rod 32 of the double-acting hydraulic cylinder 3 respectively abut against the hole wall of the mounting hole 21. When the piston rod 32 is driven to reciprocate in a first direction relative to the cylinder assembly 31, the piston rod 32 directly pushes the slide 2 to reciprocate in the first direction. That is, there is no need to provide an additional connecting member to connect the piston rod 32 and the slide 2, which simplifies the structure of the slide mechanism 10 and reduces the difficulty of assembling the slide mechanism 10. By providing the above-mentioned slide mechanism 10, the die-casting machine of this embodiment has a compact overall structure, a simple structure, and reliable operation.

[0060] In this embodiment, Figure 3 As shown, the dowel rod assembly 40 includes a plurality of dowel rods, each of which is completely identical in appearance, and the arrangement positions can also be flexibly adjusted as needed. Figures 3 to 5 As shown, the force transmission rod assembly 40 includes a first force transmission rod 401, a second force transmission rod 402 and two third force transmission rods 403, and the two ends of each force transmission rod are fixedly connected to the top plate 50 and the mounting base plate 1 respectively. Specifically, a first avoidance hole 22, a second avoidance hole 23 and two third avoidance holes 24 are provided on the skateboard 2. The first force transmission rod 401 is connected to the mounting base plate 1 after passing through the first avoidance hole 22, the second force transmission rod 402 is connected to the mounting base plate 1 after passing through the second avoidance hole 23, and the third force transmission rod 403 is connected to the mounting base plate 1 after passing through the corresponding third avoidance hole 24. It should be noted that in this embodiment, each force transmission rod is defined as the first force transmission rod 401, the second force transmission rod 402 and the third force transmission rod 403 respectively in terms of its additional function. The specific additional functions are described in detail below.

[0061] Preferably, if Figure 7 As shown, recessed grooves 212 are provided on the walls of the mounting hole 21 at both ends along the first direction, and the piston rod 32 abuts the bottom surfaces of the recessed grooves 212 at both ends along the first direction. To ensure the precision with which the piston rod 32 drives the slide 2, the precision of the fit between the piston rod 32 and the wall of the mounting hole 21 must be ensured. This embodiment, by providing recessed grooves 212 on the wall of the mounting hole 21 and abutting the piston rod 32 against the bottom surfaces of the recessed grooves 212, can reduce the area requiring fine machining on the wall of the mounting hole 21, thereby reducing the manufacturing cost of the slide mechanism 10. In this embodiment, a small clearance can be provided between the bottom surface of the recessed groove 212 and the end surface of the piston rod 32.

[0062] Preferably, if Figure 6 and Figure 7As shown, the slide mechanism 10 also includes two limit switches 5, which are connected to the mounting base 1. The two limit switches 5 are respectively configured to detect whether the slide 2 is in place in the forward and reverse directions along the first direction. When the corresponding limit switch 5 detects that the slide 2 is in place, it sends a signal to the controller of the die-casting machine, and the controller stops the oil supply component from supplying oil to the double-acting hydraulic cylinder 3, thereby stopping the piston rod 32 of the double-acting hydraulic cylinder 3. It can be understood that the oil supply component includes an oil tank and a pump. In this embodiment, as shown in FIG. Figure 6 As shown, the limit switches 5 are fixedly connected to the mounting base 1, and each limit switch 5 is correspondingly accommodated in a third avoidance hole 24. In this embodiment, the slide mechanism 10 further includes two trigger members 6, which are respectively connected to the inner walls of the two third avoidance holes 24. When the slide 2 moves in the first direction, the trigger members 6 are driven to move in the first direction. When the trigger members 6 contact the corresponding limit switch 5, the limit switch 5 recognizes that the slide 2 has moved into position.

[0063] like Figures 7 to 9 As shown, an oil chamber is formed within the cylinder assembly 31. The piston rod 32 divides the oil chamber into a first oil chamber 313 and a second oil chamber 314. The first oil chamber 313 and the second oil chamber 314 are arranged along a first direction and are not connected to each other. When oil enters the first oil chamber 313, the oil in the second oil chamber 314 is discharged, causing the piston rod 32 to move in the first direction toward the second oil chamber 314. When oil enters the second oil chamber 314, the oil in the first oil chamber 313 is discharged, causing the piston rod 32 to move in the first direction toward the first oil chamber 313.

[0064] Preferably, if Figure 6 and Figure 7 As shown, the double-acting hydraulic cylinder 3 includes two piston rods 32, and the two piston rods 32 are arranged in parallel. Correspondingly, two independently arranged oil chambers are formed in the cylinder assembly 31, and each piston rod 32 divides an oil chamber into a first oil chamber 313 and a second oil chamber 314, and the two piston rods 32 can move synchronously. In other words, the double-acting hydraulic cylinder 3 drives the slide plate 2 to move in the first direction through the two piston rods 32, so that the movement of the slide plate 2 can be smoother and more precise. In this embodiment, the two piston rods 32 are arranged at intervals along the third direction. It can be understood that in other embodiments, the double-acting hydraulic cylinder 3 can also be provided with three or more piston rods 32 and oil chambers, which is not specifically limited here.

[0065] Specifically, if Figure 7 and Figure 10As shown, the cylinder assembly 31 includes a cylinder body 311 and a cylinder cover 312. A through hole 3112 extending along a first direction is provided in the cylinder body 311, and both ends of the through hole 3112 are respectively blocked by cylinder covers 312, thereby forming an oil chamber in the cylinder assembly 31. In this embodiment, two through holes 3112 are provided on the cylinder body 311, and both ends of each through hole 3112 are blocked by cylinder covers 312, thereby forming two oil chambers in the cylinder assembly 31, that is, the entire cylinder assembly 31 includes four cylinder covers 312. In this embodiment, the cylinder body 311 is fixed to the mounting base plate 1 by a fastening assembly 4. Specifically, as shown in FIG. Figure 9 As shown, the fastening assembly 4 includes multiple bolts 41 and spring washers 42. The bolts 41 are sequentially threaded through the spring washers 42 and the cylinder body 311 before being threadedly connected to the mounting base 1. Optionally, the fastening assembly 4 also includes a pin 43. The pin 43 can penetrate the mounting base 1 from the side of the mounting base 1 facing away from the slide 2 and then be inserted into the cylinder body 311. The combined action of the bolts 41 and pin 43 ensures a precise and secure installation of the cylinder body 311.

[0066] like Figure 8 and Figure 9 As shown, the piston rod 32 includes a rod body portion 321 and a partition portion 322. The partition portion 322 is provided in the middle of the rod body portion 321. The partition portion 322 is provided in the oil chamber to separate the oil chamber into a first oil chamber 313 and a second oil chamber 314. Both ends of the rod body portion 321 respectively penetrate the cylinder cover 312 at the corresponding end and abut against the hole wall of the mounting hole 21 at the corresponding end. In this embodiment, as shown in FIG. Figure 8 As shown, the circumferential surface of the partition portion 322 of the piston rod 32 is provided with multiple first sealing grooves, each of which is provided with a first sealing ring. These multiple first sealing rings ensure a good seal between the first oil chamber 313 and the second oil chamber 314. Each cylinder head 312 is provided with a through hole for the rod body 321 to pass through. The wall surface of the through hole is provided with multiple annular second sealing grooves, each of which is provided with a second sealing ring. The provision of multiple second sealing rings ensures a tight fit between the rod body 321 and the corresponding cylinder head 312, thereby ensuring good sealing between the first oil chamber 313 and the second oil chamber 314.

[0067] like Figure 9 and Figure 10As shown, the cylinder assembly 31 is constructed with two symmetrically arranged limiting grooves 3111, which include a first mating surface 3111a and a second mating surface 3111b. The first mating surface 3111a is parallel to the mounting substrate 1, and the second mating surface 3111b is perpendicular to the first mating surface 3111a and parallel to the first direction (i.e., the X direction). The mounting hole 21 has two oppositely arranged third mating surfaces 211, which are perpendicular to the third direction (i.e., the Z direction). The surface of the slide 2 facing away from the mounting substrate 1 constitutes a fourth mating surface 26, and each second mating surface 3111b corresponds to a third mating surface 211. The cylinder assembly 31 can limit the slide 2 along the third direction through the two second mating surfaces 3111b, thereby ensuring that the cylinder assembly 31 is in the correct direction when moving in the first direction. Both first mating surfaces 3111a are in contact with the fourth mating surface 26. The cylinder assembly 31 is limited in the second direction (ie, the Y direction) by the first mating surface 3111 a , thereby further ensuring the accuracy of the direction and position of the cylinder assembly 31 when it moves along the first direction.

[0068] like Figure 8 As shown, the cylinder assembly 31 is provided with a first oil hole 315 and a second oil hole 316. The first oil hole 315 connects the interior of the first oil chamber 313 and the exterior of the cylinder assembly 31. The first oil hole 315 is used to allow oil to enter or drain from the first oil chamber 313. The second oil hole 316 connects the interior of the second oil chamber 314 and the exterior of the cylinder assembly 31. The second oil hole 316 is used to allow oil to enter or drain from the second oil chamber 314. In this embodiment, since the cylinder assembly 31 includes two first oil chambers 313 and two second oil chambers 314, two first oil holes 315 and two second oil holes 316 are correspondingly provided on the cylinder assembly 31. In this embodiment, the first oil hole 315 and the second oil hole 316 are both opened on the side of the cylinder body 311 facing the mounting base plate 1.

[0069] Preferably, if Figure 8 and Figure 11As shown, the mounting base plate 1 defines a first oil passage 11 and a second oil passage 12. The first oil passage 11 includes a first oil outlet 111 and a first oil inlet 112. The first oil inlet 112 is configured to communicate with the oil supply component, while the first oil outlet 111 is configured to communicate with the first oil chamber 313. Similarly, the second oil passage 12 includes a second oil outlet 121 and a second oil inlet 122. The second oil inlet 122 is configured to communicate with the oil supply component, while the second oil outlet 121 is configured to communicate with the second oil chamber 314. Preferably, the first oil outlet end 111 of the first oil passage 11 and the second oil outlet end 121 of the second oil passage 12 are both provided on the surface of the mounting base plate 1 facing the mounting hole 21. When the cylinder assembly 31 is installed in the mounting hole 21, the first oil hole 315 is directly opposite to the first oil outlet end 111. At this time, the first oil hole 315 connects the first oil chamber 313 and the first oil passage 11; the second oil hole 316 is directly opposite to the second oil outlet end 121. At this time, the second oil hole 316 connects the second oil chamber 314 and the second oil passage 12. In this embodiment, by providing the first oil passage 11 and the second oil passage 12 in the mounting base plate 1, the oil circuits can be directly connected after the cylinder assembly 31 is installed, that is, there is no need to provide an additional connecting joint. This not only simplifies the structure of the slide mechanism 10, but also improves the installation efficiency of the slide mechanism 10.

[0070] Since the double-acting hydraulic cylinder 3 in this embodiment includes two first oil chambers 313 and two second oil chambers 314, as shown in FIG. Figure 11 As shown, the first oil passage 11 includes two first oil outlets 111, each of which is disposed opposite a first oil hole 315. The second oil passage 12 includes two second oil outlets 121, each of which is disposed opposite a second oil hole 316. It should be noted that when oil is introduced into the first oil inlet 112, the two first oil outlets 111 simultaneously feed oil into the two first oil chambers 313. Simultaneously, the oil in the two second oil chambers 314 is discharged through the two second oil inlet 122, and ultimately discharged from the second oil inlet 122.

[0071] like Figure 11 As shown, to ensure that the first oil passage 11 supplies oil to the two first oil chambers 313 and the second oil passage 12 supplies oil to the two second oil chambers 314, the extension paths of the first oil passage 11 and the second oil passage 12 are both tortuous. When fabricating the first oil passage 11 and the second oil passage 12, process holes can be machined on the sidewalls of the mounting base 1 and then sealed.

[0072] Preferably, if Figure 11As shown, the first oil inlet end 112 of the first oil passage 11 is arranged on the surface of the mounting base 1 facing the slide 2, and the second oil inlet end 122 of the second oil passage 12 is also arranged on the surface of the mounting base 1 facing the slide 2. Figure 12 and Figure 13 As shown, the first force transmission rod 401 defines a first oil inlet channel 4011 extending along its axial direction. The end of the first oil inlet channel 4011 away from the mounting base plate 1 is used to communicate with an external oil supply component. The end of the first oil inlet channel 4011 near the mounting base plate 1 is directly opposite the first oil inlet end 112, thereby communicating with the first oil passage 11. The second force transmission rod 402 defines a second oil inlet channel 4021 extending along its axial direction. The end of the second oil inlet channel 4021 away from the mounting base plate 1 is used to communicate with an external oil supply component. The end of the second oil inlet channel 4021 near the mounting base plate 1 is directly opposite the second oil inlet end 122, thereby communicating with the second oil passage 12.

[0073] At this time, if Figure 11 and Figure 13 As shown by the dotted arrows in the figure, the external oil supply component can sequentially supply oil to the first oil chamber 313 through the first oil inlet channel 4011, the first oil passage channel 11, and the first oil hole 315. At the same time, the oil in the second oil chamber 314 can be discharged to the external oil supply component through the second oil hole 316, the second oil passage channel 12, and the second oil inlet channel 4021. In other words, the die-casting machine of this embodiment can supply oil to the first oil chamber 313 and the second oil chamber 314 without arranging additional pipelines by respectively providing the first oil inlet channel 4011 and the second oil inlet channel 4021 in the first force transmission rod 401 and the second force transmission rod 402, and providing the first oil passage channel 11 and the second oil passage channel 12 in the mounting base plate 1. This reduces the number of external pipelines and connecting joints of the die-casting machine, thereby avoiding the problem of pipeline entanglement during the operation of the die-casting machine.

[0074] like Figure 12 and Figure 13 As shown, each third force transmission rod 403 has a wire passage 4031 defined therein. The cable enters the wire passage 4031 from the end of the third force transmission rod 403 away from the mounting base plate 1 and exits the wire passage 4031 from the end closer to the mounting base plate 1, then reaches the third avoidance hole 24 and connects with the corresponding limit switch 5 within the third avoidance hole 24. By providing the wire passage 4031 within the third force transmission rod 403, the cables (including power cables and signal cables) connected to the limit switch 5 are not exposed, thereby preventing the cables from being damaged by long-term use or becoming entangled with other components.

Those skilled in the art will readily vary the specific embodiments and scope of application based on the principles of the present invention, and this specification should not be construed as limiting the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the claims.
