Description

Technical Field

[0001] This invention relates to an installation device, and more particularly to a steel sleeve positioning and installation device for an embedded steel sleeve mold. Background Technology

[0002] During the manufacturing process of the embedded steel sleeve mold, the steel sleeve is generally required to be installed on the moving mold positioning mandrel of the mold. When the steel sleeve is placed on the moving mold positioning mandrel of the mold, it needs to be continuously hammered so that the steel sleeve is completely pressed into the moving mold positioning mandrel of the mold.

[0003] Currently, the steel sleeve is installed using a transition fit. However, due to the excessively high temperature of the mold, the steel sleeve needs to be manually hammered in, which is difficult for personnel. Furthermore, the force and position of each hammering action are inconsistent, affecting the installation of the steel sleeve. In addition, the steel sleeve moves around during the die-casting filling process, resulting in a low die-casting qualification rate of the shell.

[0004] Therefore, there is a need for a steel sleeve positioning and installation device for embedded steel sleeve molds that can replace manual installation of steel sleeves on molds and avoid the impact of inconsistent force and position during installation. Summary of the Invention

[0005] To overcome the drawback that inconsistent force and position during each tapping by a person affects the installation of the steel sleeve, this invention provides a steel sleeve positioning and installation device for an embedded steel sleeve mold that can replace manual installation of the steel sleeve on the mold and avoid the impact of inconsistent tapping force and position on the installation.

[0006] This invention is achieved through the following technical means:

[0010] Further explanation includes a progressive pressurization device for increasing the force of the striking column. The progressive pressurization device includes an internal threaded slide plate, an external threaded block, a screw spring, a vertical rod, a drive ball, and a handle. The internal threaded slide plate is circumferentially connected to the inner side of the hollow column. The hollow tube passes through the middle of the internal threaded slide plate. The lower part of the hollow tube is symmetrically and slidably connected to external threaded blocks for moving the internal threaded slide plate. Both sides of the external threaded blocks are in contact with the inner side of the internal threaded slide plate. Four screw springs are connected between the inner sides of the left and right sides of the external threaded blocks. The vertical rod is slidably connected to the middle of the top of the hollow tube. The lower part of the vertical rod is circumferentially fixed with a drive ball for limiting the external threaded blocks. The drive ball is in contact with the left and right sides of the external threaded blocks. A handle is fixed to the top of the vertical rod.

[0011] Further explanation includes an automatic unlocking device for resetting the drive ball. The automatic unlocking device includes a vertical plate, a locking plate, a locking rod, a return spring, and a steel ball. The vertical plate is symmetrically slidably connected to the top of the hollow column. Two locking plates for moving the handle are fixed between the upper inner sides of the vertical plates on both sides. The two locking plates are located on the upper and lower sides of the handle. The locking rod is symmetrically slidably connected to the upper inner side of the hollow tube. The outer ends of the locking rods on both sides are connected to the inner side of the hollow tube with a return spring. A steel ball is fixedly fitted on the upper part of the vertical rod, and the steel ball contacts the locking rods on both sides.

[0012] Further explanation includes a lifting device for placing the mold. The lifting device includes a placement plate, a sliding clamping plate, clamping springs, a U-shaped rod, a locking block, and a grooved rod. The placement plate for placing the mold is slidably connected between the lower left and right sides of the frame. A sliding clamping plate for clamping and fixing the mold is slidably connected to the top right side of the placement plate. Two clamping springs are connected between the lower left side of the sliding clamping plate and the inner side of the placement plate. A U-shaped rod is slidably connected to the right side of the placement plate. Both ends of the left side of the U-shaped rod are fixedly connected to the lower right side of the sliding clamping plate. A locking block is fixedly connected to the middle of the inner right side of the U-shaped rod. A grooved rod for limiting the locking block is fixedly connected to the bottom right side of the frame. The grooved rod engages with the locking block.

[0013] Further explanation includes a damping mechanism for absorbing the impact of the striking column. The damping mechanism includes a damping frame and a damping spring. The damping frame for buffering and reducing the impact of the striking column is slidably connected to the bottom center of the helical drive cylinder. The damping spring is connected between the top of the damping frame and the inner side of the helical drive cylinder.

[0014] Further explanation includes a spacing adjustment mechanism for adjusting the position of the striking posts. The spacing adjustment mechanism includes an arc-shaped circular plate, a four-jaw clip, and a clip spring. The arc-shaped circular plate for moving the striking posts is rotatably connected to the middle of the bottom of the hollow post. The four striking posts pass through the holes in the arc-shaped circular plate. The four-jaw clip is slidably connected to the middle of the arc-shaped circular plate. A clip spring is connected between the bottom of the four-jaw clip and the inner side of the arc-shaped circular plate. Four clip holes are evenly spaced on the bottom of the hollow post, and the top of the four-jaw clip is located in the clip hole.

[0015] The significant advancement of this invention lies in:

[0016] 1. Place the mold with the steel sleeve inside the frame and align it with the striking column. Start the drive device to drive the lifting device. The lifting device will cause the striking column to move up and down. The up and down movement of the striking column will strike the steel sleeve, thus knocking the steel sleeve into the moving mold positioning mandrel of the mold. In this way, there is no need for manual striking of the steel sleeve, avoiding the impact of inconsistent striking force and position on the installation of the steel sleeve.

[0017] 2. Under the action of the gradual pressurization device, each time the striking column continuously strikes the steel sleeve, the gradual pressurization device can continuously increase the force of the striking column, so that the steel sleeve is better pressed into the moving mold positioning mandrel of the mold.

[0018] 3. Under the action of the automatic unlocking device, each time the striking column finishes striking the steel sleeve, the automatic unlocking device will drive the handle to reset, which will cause the drive ball to move upward and reset. In this way, there is no need to pull the handle to reset the drive ball, which is convenient and quick. Attached Figure Description

[0041] Example 1

[0042] A steel sleeve positioning and mounting device for an embedded steel sleeve mold includes a frame 1, a mounting bracket 4, a hollow column 5, an L-shaped slider 6, a striking column 7, a horizontal spring 8, a lifting device 9, and a driving device 10. (See also...) Figures 1-10As shown, a mounting bracket 4 is installed in the top center of the frame 1 by welding. A hollow column 5 is fixed to the inside of the mounting bracket 4. Four L-shaped sliders 6 are slidably connected to the inside of the hollow column 5 at even intervals along the circumference. A striking column 7 is slidably connected to the inside of each of the four L-shaped sliders 6. The bottom ends of the four striking columns 7 slide through the bottom of the hollow column 5. When the striking column 7 moves downward, it can strike the steel sleeve 3. Horizontal springs 8 are connected between the outer surface of the four striking columns 7 and the inside of the four L-shaped sliders 6. A lifting device 9 is set between the frame 1 and the hollow column 5. When the lifting device 9 operates, it can drive the striking column 7 to move up and down. A driving device 10 is set between the frame 1 and the lifting device 9. The driving device 10 can drive the lifting device 9 to operate.

[0043] The lifting device 9 includes a screw drive cylinder 91, a hollow tube 92, a pressure plate 93, a limit block 931, and a pressure spring 94. Please refer to [link / reference]. Figures 7-10 As shown, a pressure plate 93 is circumferentially connected to the inner side of the hollow column 5. The bottom of the pressure plate 93 contacts the top of the L-shaped slider 6, allowing the pressure plate 93 to drive the L-shaped slider 6 to move downwards. A pressure spring 94 is connected to the top of the pressure plate 93, and the tail end of the pressure spring 94 contacts the inner top of the hollow column 5. A hollow tube 92 is rotatably connected between the top middle of the hollow column 5 and the top of the frame 1. The hollow tube 92 passes through the middle of the pressure plate 93, and a spiral drive cylinder 91 is installed at the bottom end of the hollow tube 92 by welding. The spiral drive cylinder 91 contacts the inner ends of the four L-shaped sliders 6. When the spiral drive cylinder 91 rotates clockwise, it can drive the L-shaped sliders 6 to move upwards. A limit block 931 is installed circumferentially in the middle of the inner side of the hollow column 5 by welding. When the pressure plate 93 moves downwards and contacts the limit block 931, the limit block 931 can limit the pressure plate 93.

[0044] The drive unit 10 includes a drive motor 101, a rotating shaft 102, and a transmission assembly 103. Please refer to [link / reference]. Figure 5 and Figure 6 As shown, a drive motor 101 is installed in the middle of the top right side of the frame 1 by bolt connection. The output shaft of the drive motor 101 is connected to a rotating shaft 102 by a coupling. The top of the rotating shaft 102 passes through the frame 1. A transmission assembly 103 is connected between the top of the rotating shaft 102 and the middle of the outer side of the hollow tube 92. The transmission assembly 103 consists of two pulleys and a flat belt. One pulley is fixedly mounted on the top of the rotating shaft 102, and the other pulley is fixedly mounted on the middle of the outer side of the hollow tube 92. The flat belt is wound between the two pulleys.

[0045] First, place the mold 2 with the steel sleeve 3 positioned inside the bottom of the frame 1, and use an object to elevate the mold 2 to a suitable position, aligning the steel sleeve 3 with the four striking pillars 7. Start the drive device 10, which in turn drives the lifting device 9. The lifting device 9 moves the L-shaped sliders 6 on both sides upwards, which in turn moves the striking pillars 7 upwards. Simultaneously, the lifting device 9 disengages from the L-shaped sliders 6 on both sides, causing the striking pillars 7 on both sides to move downwards and strike the steel sleeve 3, thus pressing the steel sleeve 3 onto the moving mold positioning spindle of the mold 2. When the lifting device 9 continues to move the striking pillars 7 upwards to reset, it disengages from the striking pillars 7 on both sides, and the striking pillars 7 move downwards to strike the steel sleeve 3. This process is repeated, continuously pressing the steel sleeve 3 onto the moving mold positioning spindle of the mold 2, preventing the steel sleeve 3 from shifting or dislodging. When the steel sleeve 3 is fully pressed on the moving mold positioning mandrel of the mold 2, the drive device 10 is turned off, the drive device 10 stops driving the lifting device 9, and the four striking columns 7 also stop moving up and down, so that the mold 2 with the steel sleeve 3 is removed.

[0046] Initially, the pressure spring 94 is in a compressed state. When the drive device 10 is started, the drive device 10 operates, causing the hollow tube 92 to rotate clockwise. The clockwise rotation of the hollow tube 92 causes the spiral drive cylinder 91 to rotate clockwise. The spiral drive cylinder 91 rotates clockwise and disengages from the L-shaped sliders 6 on the left and right sides. Due to the action of the pressure spring 94, the pressure plate 93 moves downward, causing the L-shaped sliders 6 on the left and right sides to move downward. The downward movement of the L-shaped sliders 6 on the left and right sides causes the striking posts 7 on the left and right sides to move downward, striking the steel sleeve 3, thus pressing the steel sleeve 3 into the moving mold positioning mandrel of the mold 2. When the spiral drive cylinder 91 continues to rotate clockwise, the spiral drive cylinder 94... 1. The L-shaped sliders 6 on both sides move upward, which in turn moves the striking posts 7 on both sides upward. This upward movement of the L-shaped sliders 6 also moves the pressure plate 93 upward, compressing the pressure spring 94. As the spiral drive cylinder 91 continues to rotate forward and disengages from the L-shaped sliders 6, the pressure plate 93 moves downward, causing the striking posts 7 on both sides to move downward and strike the steel sleeve 3. This process repeats continuously, pressing the steel sleeve 3 onto the moving mold positioning mandrel of the mold 2. When the steel sleeve 3 is fully pressed onto the moving mold positioning mandrel of the mold 2, the drive device 10 is turned off. The drive device 10 stops driving the hollow tube 92 to rotate forward, and the hollow tube 92 stops driving the spiral drive cylinder 91 to rotate forward. The four striking posts 7 then stop moving up and down.

[0047] After mold 2 is placed, drive motor 101 is started. Drive motor 101 drives rotating shaft 102 to rotate clockwise. Rotating shaft 102 drives transmission component 103 to rotate clockwise. Rotating transmission component 103 drives hollow tube 92 to rotate clockwise, which causes spiral drive cylinder 91 to move the striking column 7 up and down to strike steel sleeve 3. When steel sleeve 3 is completely pressed on the moving mold positioning mandrel of mold 2, drive motor 101 is turned off. Drive motor 101 stops driving rotating shaft 102 to rotate clockwise, and rotating shaft 102 stops driving hollow tube 92 to rotate clockwise through transmission component 103.

[0048] Example 2

[0049] Based on Embodiment 1, a gradual pressurization device 11 is also included. The gradual pressurization device 11 includes an internally threaded slide plate 111, an externally threaded block 112, a block spring 113, a vertical rod 114, a drive ball 115, and a handle 116. Please refer to [link to documentation]. Figure 7 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, an internally threaded slide plate 111 is slidably connected to the inner side of the hollow column 5 along the circumferential direction. The hollow tube 92 passes through the middle of the internally threaded slide plate 111. Externally threaded blocks 112 are symmetrically slidably connected to the lower part of the hollow tube 92. Both externally threaded blocks 112 on the left and right sides are in contact with the inner side of the internally threaded slide plate 111. When the externally threaded blocks 112 rotate, they can drive the internally threaded slide plate 111 to move. Four screw springs 113 are connected between the inner sides of the externally threaded blocks 112 on the left and right sides. A vertical rod 114 is slidably connected to the middle of the top of the hollow tube 92. A drive ball 115 is fixedly mounted on the lower part of the vertical rod 114 along the circumferential direction. The drive ball 115 is in contact with the externally threaded blocks 112 on the left and right sides. The drive ball 115 can limit the externally threaded blocks 112. A handle 116 is installed at the top of the vertical rod 114 by welding.

[0050] It also includes an automatic unlocking device 12, which comprises a vertical plate 121, a locking plate 122, a locking lever 123, a return spring 124, and a steel ball 125. Please refer to [link / reference needed]. Figure 7 , Figure 15 and Figure 16 As shown, vertical plates 121 are symmetrically slidably connected to the top of the hollow column 5. Two locking plates 122 are fixedly connected between the upper inner sides of the vertical plates 121 on both sides. The two locking plates 122 are located on the upper and lower sides of the handle 116. When the locking plates 122 move, they can drive the handle 116 to move. Locking rods 123 are symmetrically slidably connected to the upper inner side of the hollow tube 92. The outer ends of the locking rods 123 on both sides are connected to the inner side of the hollow tube 92 with return springs 124. A steel ball 125 is fixedly fitted on the upper part of the vertical rod 114. The steel ball 125 is in contact with the locking rods 123 on both sides.

[0051] It also includes a lifting device 13, which includes a placement plate 131, a sliding clamping plate 132, a clamping spring 133, a U-shaped rod 134, a locking block 135, and a grooved rod 136. Please refer to [link / reference needed]. Figure 5 , Figure 17 and Figure 18 As shown, a placement plate 131 is slidably connected between the lower parts of the left and right sides of the frame 1. The placement plate 131 is used to place the mold 2. A sliding clamping plate 132 is slidably connected to the top right side of the placement plate 131. When the mold 2 is placed on the placement plate 131, the sliding clamping plate 132 can clamp and fix the mold 2. Two clamping springs 133 are connected between the lower left side of the sliding clamping plate 132 and the inner side of the placement plate 131. A U-shaped rod 134 is slidably connected to the right side of the placement plate 131. Both ends of the left side of the U-shaped rod 134 are installed by welding to the lower right side of the sliding clamping plate 132. A locking block 135 is fixedly connected to the middle of the inner right side of the U-shaped rod 134. A grooved rod 136 is fixedly connected to the bottom right side of the frame 1. The grooved rod 136 engages with the locking block 135. When the locking block 135 contacts the grooved rod 136, the grooved rod 136 can limit the locking block 135.

[0052] Initially, the four screw springs 113 are in a stretched state. When the drive motor 101 starts, the hollow tube 92 rotates forward, causing the left and right external thread blocks 112 to rotate forward. The left and right external thread blocks 112 rotate forward, causing the internal thread slide plate 111 to move downward through the threads. The downward movement of the internal thread slide plate 111 compresses the pressure spring 94. Then, when the spiral drive cylinder 91 rotates forward and disengages from the L-shaped slider 6, the pressure plate 93 moves downward, causing the striking column 7 to move downward through the L-shaped slider 6 to strike the steel sleeve 3. As the internal thread slide plate 111 moves downward continuously, the pressure spring 94 is continuously compressed, and the striking force of the striking column 7 on the steel sleeve 3 becomes greater and greater. When the steel sleeve 3 presses on the moving mold positioning mandrel of the mold 2, the drive motor 101 is turned off, the hollow tube 92 stops driving the left and right external thread blocks 112 to rotate forward, and the internal thread slide plate 111 also stops moving downward. Pushing the handle 116 downward moves the vertical rod 114 downward, and the vertical rod 114 moves downward, driving the drive ball 115 downward. The drive ball 115 moves downward and disengages from the left and right external thread blocks 112. Due to the action of the four screw block springs 113, the left and right external thread blocks 112 move inward and disengage from the internal thread slide plate 111. Due to the action of the pressure spring 94, the internal thread slide plate 111 moves upward and resets. Pulling the handle 116 again drives the drive ball 115 upward through the vertical rod 114. The drive ball 115 moves upward and resets, driving the left and right external thread blocks 112 to move outward and reset. The left and right external thread blocks 112 reset and contact the inside of the internal thread slide plate 111, and the four screw block springs 113 are stretched. In this way, the striking force of the striking column 7 on the steel sleeve 3 can be gradually increased, so that the steel sleeve 3 can be better pressed into the moving mold positioning mandrel of the mold 2.

[0053] When the internal thread slide plate 111 moves downward, it causes the left and right vertical plates 121 to move downward, which in turn causes the two locking plates 122 to move downward. The two locking plates 122 then cause the handle 116 to move downward, which in turn causes the vertical rod 114 to move downward. The vertical rod 114 then causes the steel ball 125 to move downward, which in turn causes the left and right locking rods 123 to move outward. The left and right return springs 124 are compressed. When the driving ball 115 moves downward and disengages from the left and right external thread blocks 112, the steel ball 125 also... As the left and right locking levers 123 move inward to reset due to the action of the left and right return springs 124, the internal thread slide plate 111 moves upward to reset. This upward movement of the internal thread slide plate 111, via the left and right vertical plates 121, drives the two locking plates 122 to move upward to reset. The upward movement of the locking plates 122 drives the handle 116 to move upward to reset, which in turn causes the vertical rod 114 to drive the steel ball 125 to move upward to reset. The steel ball 125 slides over the left and right locking levers 123, and the vertical rod 114 also drives the drive ball 115 to reset, causing the left and right external thread blocks 112 to move outward to reset. Thus, there is no need to manually pull the handle 116 to reset the drive ball 115, making it convenient and quick.

[0054] First, pull the U-shaped rod 134 to the right. This movement causes the locking block 135 to move to the right and disengage from the grooved rod 136. The U-shaped rod 134 also moves the sliding clamping plate 132 to the right, stretching the clamping springs 133 on both sides. Then, place the mold 2 on the placement plate 131 and release the U-shaped rod 134. Due to the action of the clamping springs 133, the sliding clamping plate 132 moves to the left and resets, contacting the mold 2. The sliding clamping plate 132 clamps and fixes the mold 2. Simultaneously, the sliding clamping plate 132, through the U-shaped rod 134, causes the locking block 135 to move to the left and reset, contacting the grooved rod 136. The locking block 135 and the grooved rod 136 cooperate to fix the U-shaped rod 134, thus fixing the sliding clamping plate 132. Now, the steel sleeve 3 can be struck. When the steel sleeve 3 is pressed into the moving mold positioning mandrel of the mold 2, the mold 2 can be removed from the placement plate 131. In this way, the height of the mold 2 can be adjusted as needed without the need to use any items to elevate it, which is convenient and quick.

[0055] Example 3

[0056] Based on Embodiments 1 and 2, a shock-absorbing mechanism 14 is also included. The shock-absorbing mechanism 14 includes a shock-absorbing frame 141 and a shock-absorbing spring 142. Please refer to [link / reference]. Figure 7 and Figure 19As shown, a damping frame 141 is slidably connected to the bottom center of the spiral drive cylinder 91. When the striking column 7 moves downward and contacts the damping frame 141, the damping frame 141 can buffer and reduce the shock of the striking column 7. A damping spring 142 is connected between the top of the damping frame 141 and the inner side of the spiral drive cylinder 91.

[0057] It also includes a spacing adjustment mechanism 15, which includes an arc-shaped circular plate 151, a four-jaw clamp 152, and a clamp spring 153. Please refer to [link / reference needed]. Figure 7 , Figure 19 and Figure 20 As shown, an arc-shaped circular plate 151 is rotatably connected to the bottom center of the hollow column 5. Four striking columns 7 pass through the holes in the arc-shaped circular plate 151. When the arc-shaped circular plate 151 rotates, it can drive the striking columns 7 to move. A four-jaw clip 152 is slidably connected to the middle of the arc-shaped circular plate 151. The four-jaw clip 152 can limit the arc-shaped circular plate 151. A clip spring 153 is connected between the bottom of the four-jaw clip 152 and the inner side of the arc-shaped circular plate 151. Four clip holes 154 are evenly spaced on the bottom of the hollow column 5. The top of the four-jaw clip 152 is located in the clip hole 154.

[0058] When the striking column 7 moves downward to strike the steel sleeve 3, it contacts the damping frame 141. Due to the action of the damping spring 142, the damping frame 141 buffers and absorbs the shock of the striking column 7. When the striking column 7 moves upward to reset, it disengages from the damping frame 141. This avoids the striking column 7 from having an excessively long downward stroke, which would prevent it from being driven by the screw drive cylinder 91.

[0059] After mold 2 is placed, pull the four-jaw clamp 152 downwards. The clamp spring 153 is stretched, and the four-jaw clamp 152 moves downwards, disengaging from the four clamping holes 154. Then, twist the four-jaw clamp 152 to rotate alternately in both directions. This alternating rotation of the four-jaw clamp 152 drives the arc-hole circular plate 151 to rotate alternately in both directions. This alternating rotation of the arc-hole circular plate 151 drives the four striking posts 7 to move inwards and outwards. When the four striking posts 7 move inwards and outwards to the appropriate position to strike the steel sleeve 3, stop twisting the four-jaw clamp 152. The arc-hole circular plate 151 stops rotating alternately in both directions. Release the four-jaw clamp 152. Due to the action of the clamp spring 153, the four-jaw clamp 152 moves upwards and resets, inserting into the clamping holes 154 to limit the arc-hole circular plate 151. In this way, the striking posts 7 can adapt to steel sleeves 3 of different sizes.
