Description

Technical Field

[0001] This utility model relates to the field of inlay machine technology, and more specifically, to an upper mold pressure sliding device for a hot inlay machine. Background Technology

[0002] In the field of mounting machines, mounting samples requires fusing the sample and mounting material together under high temperature and pressure. This process involves a complex environment with high temperature, pressure, and mechanical damage. To prevent accidents, the main body needs to be sealed off. Conventional sealing involves installing a simple cover or manually adding a protective baffle. This operation requires manual contact with high-temperature mechanical parts, which not only requires proper protective measures but also has low replacement efficiency. It is necessary to wait for the previous mounting operation to cool down before continuing. Especially after removing the baffle, operations such as adding material are required, resulting in low efficiency of hot mounting. At the same time, there are many uncertainties, such as inadequate shielding, which affects the mounting effect and causes mounting failure, seriously affecting the efficiency of operation and the accuracy of sample testing. Summary of the Invention

[0003] In view of this, the present invention proposes an upper mold pressure sliding device for a hot mounting machine, which aims to solve the problems of cumbersome closed operation and low processing efficiency of existing hot mounting machines.

[0004] This utility model proposes an upper mold pressure sliding device for a hot mounting machine. The device includes: a support base; an upper mold pressing mechanism, slidably disposed on the support base along the length direction of the support base, for driving the upper mold to adjust its vertical position in a closed processing position, so as to drive the upper mold to press down into the hot mounting cavity of the hot mounting machine, and cooperate with the lower mold in the hot mounting cavity to perform thermosetting pressing and molding of the mounting sample and mounting powder; and a lateral driving mechanism, the power output end of which is connected to the upper mold pressing mechanism, for driving the upper mold pressing mechanism to move laterally, so as to switch to a closed processing position for thermosetting pressing and molding, or to switch to a clearance feeding position to make way for the feeding port of the hot mounting cavity.

[0005] Furthermore, the aforementioned upper mold pressure sliding device for the hot mounting machine includes an upper mold pressing mechanism comprising: a sealed shielding housing with a vertical moving bracket inside; a vertical moving rod, which is vertically adjustable and mounted on the vertical moving bracket for connecting the upper mold of the hot mounting machine; and a vertical drive assembly, the power output end of which is connected to the vertical moving rod for driving the vertical moving rod to adjust its position in the vertical direction, thereby moving the upper mold vertically and switching it between an open and closed state. This allows the upper mold to move downward through the feeding port on the support base into the hot mounting cavity, switch to the closed state, and cooperate with the lower mold to complete the sample processing.

[0006] Furthermore, in the above-mentioned upper mold pressure sliding device for a hot mounting machine, the vertical drive assembly includes: a vertical drive component and a rotating component; wherein, the rotating component is rotatably sleeved on the outer periphery of the vertical moving rod, the rotating component is connected to the power output end of the vertical drive component, and the rotating component is connected to the vertical moving rod for transmission, for rotating under the drive of the drive component, and converting the rotation of the rotating component into the vertical movement of the vertical moving rod.

[0007] Furthermore, in the above-mentioned upper mold pressure sliding device for the hot mounting machine, the rotating component and the vertical driving component are arranged with their axes spaced apart, and the power input end of the rotating component and the power output end of the vertical driving component are connected by an axis indexing component. The axis indexing component is used to drive the rotating component to rotate around its axis under the driving action of the vertical driving component.

[0008] Furthermore, in the aforementioned upper mold pressure sliding device for the hot inserting machine, the inner wall of the rotating component is provided with an internal thread, and the outer wall of the vertical moving rod is provided with an external thread that matches the internal thread, forming a ball screw pair.

[0009] Furthermore, in the above-mentioned upper mold pressure sliding device for the hot mounting machine, a vertical slider is provided on the vertical moving rod for moving up and down synchronously with the vertical moving rod; an upper limit switch and a lower limit switch are provided on one side of the vertical moving rod at intervals to limit the upper and lower positions of the vertical slider.

[0010] Furthermore, in the aforementioned upper mold pressure sliding device for the hot mounting machine, the sealed housing is provided with a guide plate, which is sleeved on the vertical moving rod. The inner wall of the guide plate is provided with a guide block, and the outer wall of the vertical moving rod is provided with a strip-shaped guide groove arranged circumferentially. The guide block is slidably disposed in the strip-shaped guide groove to prevent the rotation of the vertical moving rod and to guide the vertical movement of the vertical moving rod.

[0011] Furthermore, in the above-mentioned upper mold pressure sliding device for the hot mounting machine, the lateral drive mechanism includes: a lateral drive component; a transmission component, the power input end of which is connected to the power output end of the drive component, and the power output end of which is connected to the upper mold pressing mechanism, for converting the rotation of the lateral drive component into the lateral movement of the upper mold pressing mechanism, so as to realize the position switching of the upper mold pressing mechanism.

[0014] The upper mold pressing and sliding device for a hot mounting machine provided by this utility model drives the upper mold pressing mechanism to move laterally through a lateral drive mechanism, so that the upper mold pressing mechanism switches to a closed processing position. In the closed processing position, the upper mold is driven by the upper mold pressing mechanism to adjust its vertical position. This not only blocks and seals the feeding port of the hot mounting machine, but also drives the upper mold to press down into the hot mounting cavity of the hot mounting machine. Together with the lower mold in the hot mounting cavity, the mounting sample and mounting powder are thermoset and pressed into shape, thus blocking and sealing the feeding port of the hot mounting machine. The upper mold pressing mechanism can also switch to a clearance feeding position under the drive of the lateral drive mechanism, clearing the feeding port of the hot mounting cavity, and then performing related operations from the feeding port, such as taking out the completed sample or adding material for processing the next sample. This solves the problems of cumbersome closed operation and low processing efficiency of existing hot mounting machines. Meanwhile, the sealing operation of this device does not require contact with high-temperature mechanical parts, and it improves the sealing effect, solving the problems of cumbersome sealing operations, low replacement efficiency, and inadequate sealing affecting the inlay effect and causing inlay failure in traditional hot mounting machines. In addition, the device has a simple structure, good sealing effect, high installation efficiency, and stable operation. Attached Figure Description

Detailed Implementation

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] See Figures 1 to 5The figure illustrates a preferred structure of the upper mold pressure sliding device for a hot mounting machine provided by an embodiment of the present invention. As shown in the figure, the upper mold pressure sliding device for a hot mounting machine includes: a support base 1, an upper mold pressing mechanism 2, and a transverse drive mechanism 3.

[0018] The upper die pressing mechanism 2 is slidably disposed on the support base 1 along the length direction of the support base 1. It is used to drive the upper die 8 to adjust its vertical position in the closed processing position so as to drive the upper die 8 to press down into the hot mounting cavity of the hot mounting machine, and cooperate with the lower die in the hot mounting cavity to perform thermosetting pressing and molding of the mounting sample and mounting powder.

[0019] Specifically, the support base 1 can be a support plate structure, serving as the top cover of the hot mounting machine, or it can be fixedly installed on the top cover of the hot mounting machine. This embodiment does not impose any limitations on it. The upper die pressing mechanism 2 runs along the length direction of the support base 1 (e.g., ...). Figure 1 The upper die (shown horizontally) is slidably positioned above the support base 1. It can be switched to a closed processing position directly above the feeding port of the hot mounting machine to seal the feeding port. The upper die 8 is driven by the upper die pressing mechanism 2 to adjust its vertical position, thereby driving the upper die 8 to be pressed down through the feeding port into the hot mounting cavity of the hot mounting machine. It then works with the lower die inside the hot mounting cavity to thermoset and press the mounting sample and mounting powder into shape. In this embodiment, the upper die pressing mechanism 2 can be connected to a drag chain 4. The fixed end of the drag chain 4 can be installed on the support base 1. The drag chain 4 can be flexibly bent to adjust its position as the upper die pressing mechanism 2 moves laterally.

[0020] The power output end of the lateral drive mechanism 3 is connected to the upper mold pressing mechanism 2, and is used to drive the upper mold pressing mechanism 2 to move laterally, so as to switch to the closed processing position for thermosetting pressing, or to switch to the clearance feeding position to make way for the feeding port of the hot insert cavity.

[0021] Specifically, the lateral drive mechanism 3 can be located below the support base 1. The fixed end of the lateral drive mechanism 3 can be fixedly installed on the bottom wall of the support base 1, and the power output end can extend to the top of the support base 1 and connect with the upper mold pressing mechanism 2. This allows the upper mold pressing mechanism 2 to move laterally, enabling it to move to a closed processing position. In this closed processing position, the upper mold pressing mechanism 2, in conjunction with the lower mold, performs thermosetting pressing. It can also move to a clearance feeding position to allow for the feeding port of the hot-mounted cavity, facilitating the feeding or removal of the completed sample from the hot-mounted cavity. Simultaneously, the vertical movement of the upper mold pressing mechanism 2 controls the pressure applied by the upper mold, preventing inconvenience to manual operation and achieving a better sealing effect and higher operational efficiency during the upper mold and sealing process.

[0022] See also Figures 1 to 5The support base 1 may be provided with a sliding guide seat 5 for sliding support of the upper mold pressing mechanism 2.

[0023] Specifically, the upper die pressing mechanism 2 is slidably mounted on the top wall of the sliding guide seat 5. To improve the stability of the sliding of the upper die pressing mechanism 2, preferably, the sliding guide seat 5 is provided with a groove 51, and the bottom end of the upper die pressing mechanism 2 is provided with a limiting strip 6, which is slidably mounted in the corresponding groove 51. In this embodiment, the two sides of the sliding guide seat 5 (such as...) Figure 2 Both the side facing the paper and the side shown on the paper are provided with slide grooves 51. The bottom ends of the upper die pressing mechanism 2 are provided with limiting strips 6 corresponding to the slide grooves 51, which are slidably disposed within the corresponding slide grooves 51. Of course, the two slide grooves 51 can also be connected, that is, the slide grooves 51 are along the length direction perpendicular to the sliding guide seat 5 (e.g., Figure 1 The through groove (shown in the horizontal direction) penetrates the sliding guide seat 5, that is, it penetrates the sliding guide seat 5 in a direction perpendicular to the paper plane. Two limiting strips 6 are placed on both sides of the sliding guide seat 5 and their ends are slidably locked at both ends of the slide groove 51, realizing the guidance and vertical limitation of the upper die pressing mechanism 2, ensuring that the upper die pressing mechanism 2 is slidably locked above the support seat 1, especially ensuring that the bottom wall of the upper die pressing mechanism 2, that is, the bottom wall of the bottom plate 211 of the sealing housing of the upper die pressing mechanism 2, presses against the top wall of the sliding guide seat 5, ensuring the sealing and shielding effect. In this embodiment, the support seat 1 and the sliding guide seat 5 may be provided with an upper die 8 movable hole, so that the upper die 8 can slide up and down through the upper die 8 movable hole, can extend into the bottom hot insert machine for processing, or retract upward into the upper die pressing mechanism 2, avoiding interference with the movement of the upper die pressing mechanism 2.

[0024] See also Figures 1 to 5 The bottom end of the upper die pressing mechanism 2 is provided with a cleaning plate 7, which is used to press against the top wall of the sliding guide seat 5 to clean impurities on the top wall of the sliding guide seat 5, especially the hot-inserted material on the top wall of the sliding guide seat 5, as the upper die pressing mechanism 2 slides to the closed processing position. Specifically, the bottom wall of the cleaning plate 7 is flush with the bottom wall of the upper die pressing mechanism 2, i.e., the bottom wall of the bottom plate 211 of the sealing housing of the upper die pressing mechanism 2, so as to clean the hot-inserted material on the top wall. Of course, the cleaning plate 7 can be an elastic plate, such as a rubber plate, and its bottom wall can be lower than the bottom wall of the upper die pressing mechanism 2 to improve the cleaning effect. During the sliding process of the upper die pressing mechanism 2 as a whole towards the closed processing position, the cleaning plate 7 is located on the front side of the upper die pressing mechanism 2 (e.g., ...). Figure 5As shown on the right side), before the upper die pressing mechanism 2 reaches its position, cleaning is performed, that is, pushing impurities forward or to the left or right to avoid leaving them between the upper die pressing mechanism 2 and the sliding guide seat 5, which would affect the sealing effect of the sliding guide seat 5. The bottom end of the cleaning plate 7 is provided with a guide surface that slopes away from the sliding guide seat 5, such as... Figure 5 As shown, the guide surface is tilted to the right from top to bottom, that is, tilted away from the sliding guide seat 5, which can improve the cleaning effect.

[0025] See also Figures 1 to 5 The transverse drive mechanism 3 includes a transverse drive member 31 and a transmission member 32; wherein, the power input end of the transmission member 32 is connected to the power output end of the drive member, and the power output end is connected to the upper die pressing mechanism 2, which is used to convert the rotation of the transverse drive member 31 into the transverse movement of the upper die pressing mechanism 2, so as to realize the position switching of the upper die pressing mechanism 2.

[0026] Specifically, a transverse drive bracket 11 may be provided below the support base 1. This transverse drive bracket 11 can be a U-shaped bracket and can be fixedly installed on the support base 1. The transverse drive component 31 can be a DC motor, and its fixed end can be fixedly installed on the transverse drive bracket 11. The transmission component 32 can be a ball screw mechanism, such as... Figure 4 As shown, the device may include a ball screw 321 and a lateral sliding block 322 sleeved on the ball screw 321. The internal threaded hole of the lateral sliding block 322 is threadedly connected to the outer wall of the ball screw 321, realizing the conversion between rotational and linear motion. A bushing 34 may be sleeved on the screw to limit the lateral sliding block 322. There may be two bushings 34, respectively located at the left and right ends, to limit the position at the two ends. A lateral slide rail 12 may be provided on the lateral drive bracket 11 to guide the lateral linear movement of the lateral sliding block 322. The ball screw 321 is rotatably mounted on the lateral drive bracket 11, with one end (e.g., Figure 1 The left end shown is connected to the motor shaft of the DC motor through a coupling 33, so that the coupling 33 and the ball screw 321 rotate under the drive of the DC motor, thereby driving the transverse moving slider 322 to slide along the transverse slide rail 12 to achieve linear motion, thereby realizing the position switching of the upper die pressing mechanism 2.

[0027] See also Figure 4 The power output end of the transmission component 32, for example, the top of the transversely moving slider 322, is provided with a connecting block 35 that passes through the support base 1, and the bottom of the upper die pressing mechanism 2 is provided with a connecting rod 36 that connects to the connecting block 35. Specifically, the support base 1 is provided with a connecting rod 36 along its length direction (e.g., Figure 3The clearance hole 13 (shown in the horizontal direction) is provided, and the connecting block 35 is slidably inserted through the clearance hole 13. The bottom end is connected to the top end of the horizontal moving slider 322, and the top end is connected to the connecting rod 36. This enables the connection between the horizontal moving slider 322 and the upper die pressing mechanism 2, thereby achieving synchronous horizontal movement.

[0028] See also Figures 5 to 9 The upper mold pressing mechanism 2 may include: a sealing and shielding housing 21, a vertical moving rod 23, and a vertical driving assembly 24.

[0029] The sealed shielding housing 21 is equipped with a vertically movable support 22 inside.

[0030] Specifically, the sealing and shielding housing 21 is a hollow cuboid or cube shell, slidably mounted on the top wall of the sliding guide seat 5. Under the driving action of the transverse driving mechanism 3, it allows for the overall sliding adjustment of the upper mold pressing mechanism 2. It can slide to a closed processing position directly above the end cap loading port or to a yielding loading position on one side of the loading port. When the sealing and shielding housing 21 is in the closed processing position, it can shield the loading port. Combined with the up-and-down movement of the vertical moving rod 23, it allows the upper mold 8 to slide into the loading port, sealing it and achieving shielding and sealing of the sliding guide seat 5 and the support seat 1. In this embodiment, a limiting strip 6 is located at the bottom of the sealing and shielding housing 21. The limiting strip 6 is slidably mounted in the groove 51 of the sliding guide seat 5, allowing the sealing and shielding housing 21 to be slidably secured to the sliding guide seat 5, thus guiding the switching between the closed processing position and the yielding loading position. The cleaning plate 7 is located on the front side of the bottom end of the sealing shield housing 21 and can move with the sealing shield housing 21. The two sides of the connecting rod 36 are fixedly installed at the bottom end of the sealing shield housing 21. The two side plates of the sealing shield housing 21 can extend outside the cavity, and the two ends of the connecting rod 36 are fixedly installed on the extensions of the two side plates of the sealing shield housing 21. A vertical moving bracket 22 is provided inside the sealing shield housing 21. The vertical moving bracket 22 can be fixedly installed on the inner wall of the sealing shield housing 21, providing sliding support for the vertical moving rod 23 and supporting the vertical drive assembly 24.

[0031] The vertical moving rod 23 is mounted on the vertical moving bracket 22 in a vertically adjustable manner and is used to connect the upper mold 8 of the hot mounting machine.

[0032] Specifically, the top of the vertical moving rod 23 is located inside the sealed shielding housing 21, and the vertical moving rod 23 is slidably mounted on the vertical moving bracket 22 in the vertical direction. The top end of the vertical moving rod 23 can be connected to the vertical drive assembly 24 located inside the sealed shielding housing 21 to realize power input, and the bottom end can be fixedly connected to the upper mold 8 of the hot inserting machine by screws or other means to drive the upper mold 8 to move up and down, realizing the switching between the open and closed states of the upper mold 8. Figure 7 As shown, the upper mold 8 is in the open state, with the upper mold 8 and the vertical moving rod 23 located at their upper ends during vertical movement. The bottom ends of both the upper mold 8 and the vertical moving rod 23 can be positioned within the sealing and shielding housing 21. The upper mold 8 is partially embedded in the bottom plate 211 of the sealing and shielding housing 21 for material feeding and other operations. The vertical moving rod 23 drives the upper mold 8 downwards, allowing it to pass through the upper and lower sliding holes 2111 of the bottom plate 211, the upper mold 8 movable holes of the support base 1 and the sliding guide seat 5, and extend into the interior of the thermal mounting machine until it reaches the lower end of its vertical movement. At this point, the upper mold 8 is inside the thermal mounting machine, working in conjunction with the lower mold to thermoset and press the thermally mounted material and sample block between them, including processes such as pressurization and heating, heat preservation and pressure holding, and cooling and curing. After sample preparation, the upper mold 8 can move upwards with the vertical moving rod 23 to the open state to remove the prepared sample from the lower mold, thus completing the entire sample preparation process.

[0033] The power output end of the vertical drive assembly 24 is connected to the vertical moving rod 23, which is used to drive the vertical moving rod 23 to adjust its position in the vertical direction, thereby moving the upper mold 8 in the vertical direction, so that the upper mold 8 can switch between the open state and the closed state, and then the upper mold 8 can move downward through the feeding port on the support base 1 into the hot-mounting cavity, switch to the closed state, and cooperate with the lower mold to complete the sample processing.

[0034] Specifically, the fixed end of the vertical drive assembly 24 can be fixedly installed on the vertical moving bracket 22, and the power output end is connected to the vertical moving rod 23. It can drive the vertical moving rod 23 to move up and down relative to the vertical moving bracket 22 and the sealing shield housing 21, so as to drive the upper mold 8 to move in the vertical direction, so that the upper mold 8 can switch between the open state and the closed state, and then the upper mold 8 can move down through the feeding port on the support base 1 into the hot embedding cavity, switch to the closed state, and cooperate with the lower mold to complete the sample processing.

[0035] In this embodiment, a vertical slider 25 is provided on the vertical moving rod 23 for moving up and down synchronously with the vertical moving rod 23; an upper limit switch 26 and a lower limit switch 27 are provided on one side of the vertical moving rod 23 for limiting the upper and lower positions of the vertical slider 25.

[0036] Specifically, a vertical slider 25 is fixedly installed at the middle position of the vertical moving rod 23. An upper limit switch 26 and a lower limit switch 27 can be fixedly installed on the vertical moving bracket 22, respectively, limiting the upper and lower positions of the vertical slider 25. The upper limit switch 26 and the lower limit switch 27 can be connected to a control board, which is also connected to the vertical drive assembly 24. When the vertical slider 25 contacts or approaches the upper limit switch 26 or the lower limit switch 27, the vertical slider 25 can drive the contacts of the limit switches, causing closed contacts to open or open contacts to close. The change in the open / closed state of the limit switch contacts controls the drive of the vertical drive assembly 24 via the control board. The control board is a PCB control board.

[0037] In this embodiment, a guide disc 28 is provided inside the sealed housing, which is sleeved on the vertical moving rod 23. A guide block 281 is provided on the inner wall of the guide disc 28, and a strip-shaped guide groove 231 is provided on the outer wall of the vertical moving rod 23 along its circumference. The guide block 281 is slidably disposed in the strip-shaped guide groove 231 to prevent the rotation of the vertical moving rod 23 and to guide the vertical movement of the vertical moving rod 23.

[0038] Specifically, the guide plate 28 can be fixedly installed on the vertical moving bracket 22, and the guide block 281 can be slidably locked in the strip-shaped guide groove 231, which can limit and guide the vertical sliding of the vertical moving rod 23, ensuring that the vertical moving rod 23 only slides up and down, and can prevent the rotation of the vertical moving rod 23.

[0039] See also Figure 6 , Figure 7 , Figure 9 The sealed shielding housing 21 may include a top plate 213, a bottom plate 211, and four supporting side plates 212. The top plate 213 and bottom plate 211 are arranged parallel vertically, and the four supporting side plates 212 are positioned between the top plate 213 and bottom plate 211, forming a hollow cuboid or cube structure. The bottom plate 211 has vertical sliding holes 2111 penetrating the bottom plate 211, which are adapted to the upper mold 8 to allow the upper mold 8 to slide vertically through the vertical sliding holes 2111.

[0040] See also Figure 6 , Figure 7 , Figure 9The vertical moving bracket 22 may include: at least three vertical support rods 221, a horizontal support plate 222, and a limiting plate 223; wherein, the horizontal support plate 222 may be disposed inside the sealed shielding housing 21, and is supported above the bottom plate 211 of the sealed shielding housing 21 by at least three vertical support rods 221, for limiting and supporting components such as the vertical moving rod 23 and the vertical drive assembly 24; the limiting plate 223 is disposed above the horizontal support plate 222, and can limit and support the vertical drive assembly 24 to further ensure the stability of the vertical drive assembly 24.

[0041] Specifically, the horizontal support plate 222 is arranged horizontally parallel above the base plate 211, and at least three vertical support rods 221 can be arranged in a circular or polygonal pattern to support the horizontal support plate 222 on the upper side of the base plate 211. The top of each vertical support rod 221 is connected to the bottom wall of the horizontal support plate 222, and the bottom is fixed to the base plate 211. In this embodiment, there are four vertical support rods 221 arranged in a square structure around the outer periphery of the vertical moving rod 23, and the horizontal support plate 222 is a quadrilateral structure supported by the four vertical support rods 221. The limiting disc 223 is a circular structure, positioned above the horizontal support plate 222 and coaxially with the vertical support rod 221. The vertical support rod 221 slidably passes through the horizontal support plate 222 and the limiting disc 223. The limiting disc 223 provides limiting support for the driven wheel of the vertical drive assembly 24, ensuring the stability of the driven wheel's rotation and, consequently, the stability of the vertical movement of the vertical support rod 221. In this embodiment, the limiting disc 223 is connected to the horizontal support plate 222 by several isolation columns 224, which support and fix the limiting disc 223. Four isolation columns 224 are arranged circumferentially below the limiting disc 223, supporting the edge of the limiting disc 223.

[0042] See also Figure 6 , Figure 7 , Figure 9 The vertical drive assembly 24 may include: a vertical drive member 241, a rotating member 242, and an axis indexing member 243; wherein, the rotating member 242 is rotatably sleeved on the outer periphery of the vertical moving rod 23, the rotating member 242 is connected to the power output end of the vertical drive member 241, and the rotating member 242 is connected to the vertical moving rod 23 for transmission, and is used to rotate under the drive of the drive member, and to convert the rotation of the rotating member 242 into the vertical movement of the vertical moving rod 23.

[0043] Specifically, the rotating component 242 is rotatably sleeved on the outer periphery of the vertical moving rod 23, and the vertical driving component 241 can be a DC motor, whose output shaft is spaced apart on one side of the vertical moving rod 23 in a manner parallel to the axis of the vertical moving rod 23 (e.g., Figure 6 As shown on the right), the parallel arrangement, compared to the coaxial arrangement, can reduce the overall space of the upper die pressing mechanism 2, making the upper die pressing mechanism 2 structurally compact while ensuring stability. The power input end of the rotating component 242 is connected to the power output end of the vertical drive component 241 through an axis indexing component 243. The axis indexing component 243 is used to drive the rotating component 242 to rotate around the axis of the rotating component 242 under the driving action of the vertical drive component 241, so that the rotation of the rotating component 242 can be converted into the vertical movement of the vertical moving rod 23 through the transmission connection between the rotating component 242 and the vertical moving rod 23.

[0044] In this embodiment, the rotating component 242 is connected to the vertical moving rod 23 via a transmission connection, which can form a ball screw 321 pair, such as... Figure 9 As shown, the inner wall of the rotating component 242 is provided with an internal thread, and the outer wall of the vertical moving rod 23 is provided with an external thread adapted to the internal thread, forming a ball screw pair 321. Specifically, the rotating component 242 can be a ring structure, coaxial and sleeved on the vertical moving rod 23. The inner wall of the rotating component 242 is provided with an internal thread to form a threaded hole, which can form a nut structure. The outer wall of the vertical moving rod 23 is provided with an external thread adapted to the internal thread on the inner wall of the rotating component 242, as a screw structure, which is threadedly connected to the rotating component 242 to form a ball screw pair 321, so as to convert the rotation of the rotating component 242 into the linear motion of the vertical moving rod 23 along its axial direction. In this embodiment, as Figure 9 As shown, bearings 244 can be provided between the top end of the rotating component 242 and the limiting disk 223, and between the bottom end of the rotating component 242 and the transverse support plate 222. See also Figure 6 , Figure 7 , Figure 9The axis indexing component 243 can be a transmission belt mechanism, which may include a driving pulley, a driven pulley, and a transmission belt. The transmission belt is sleeved on the outer circumference of the driving pulley and the driven pulley, and can drive the driven pulley to rotate synchronously when the driving pulley rotates. Specifically, the driving pulley can be coaxially connected to the output shaft of the vertical drive component 241, and can be fixed by a connecting key or other means. The driven pulley can be an annular structure and coaxially arranged with the vertical moving rod 23 and the rotating component 242. The rotating component 242 can be embedded in the inner circumference of the driven pulley, and the two can be fixed by a connecting key to achieve synchronous rotation. Furthermore, through the threaded connection between the rotating component 242 and the vertical moving rod 23, and with the guidance of the guide plate 28, the vertical moving rod 23 performs reciprocating linear motion in the vertical direction.

[0045] In summary, the upper mold pressing and sliding device for the hot mounting machine provided in this embodiment drives the upper mold pressing mechanism 2 to move laterally via the lateral drive mechanism 3, thereby switching the upper mold pressing mechanism 2 to a closed processing position. The upper mold pressing mechanism 2, in the closed processing position, drives the upper mold 8 to adjust its vertical position. This not only achieves the blocking and sealing of the hot mounting machine's feed port but also drives the upper mold 8 to press down into the hot mounting cavity of the hot mounting machine. Together with the lower mold inside the hot mounting cavity, it thermosets and presses the mounting sample and mounting powder into shape, thus achieving the control of the hot mounting machine's feed port. The device effectively shields and seals the material. Simultaneously, the upper mold pressing mechanism 2's vertical movement controls the pressure applied to the upper mold, eliminating the inconvenience of manual operation and achieving a better sealing effect and higher operational efficiency during the upper mold and sealing process. Driven by the transverse drive mechanism 3, the upper mold pressing mechanism 2 can also switch to a clearance feeding position, clearing the feeding port of the hot mounting cavity for further operations, such as removing completed samples or adding material for the next sample. This solves the problems of cumbersome sealing operations and low processing efficiency in existing hot mounting machines. Furthermore, the sealing operation of this device does not require contact with high-temperature mechanical parts, improving the shielding and sealing effect and resolving the issues of cumbersome sealing operations, low replacement efficiency, and inadequate shielding affecting the mounting effect and causing mounting failure in traditional hot mounting machines. In addition, the device has a simple structure, good sealing effect, high installation efficiency, and stable operation.
