One end of the actuating spring is fixedly connected to the spring-loaded round plate, and the other end is fixedly connected to the actuating plate.

[0015] The present invention also provides a handle molding process, comprising the following steps:

[0016] Step 1: Align the mold with the mounting box so that it contacts the drive plate and moves within the drive rod in the drive groove, so that several compression springs are in a buffered state.

[0017] Step 2: When the drive square plate moves down, it drives the drive rack to move and meshes with the drive gear, causing the drive threaded shaft to rotate, which in turn causes the drive cross block to move within the guide rod through the guide cross block.

[0018] Step 3: Make the moving square plate on the extension plate contact the side of the mold, and position the mold in the current position through the two moving square plates;

[0019] Step 4: When the two moving square plates on the clamping and tightening mechanism move towards each other and connect to the side of the mold, it indicates that the mold has moved into place in the mounting box. By releasing the spring stop block, it moves by the reset of the clamping spring.

[0020] Step 5: The spring force generated by the resetting spring drives the two spring-stopping square plates to reset and move into the extension slot, thereby limiting the extension block on the extension plate;

[0021] Step Six: When the force applied to the mold is lost, the spring cannot return to its original position due to the limiting of the extension block, and the elastic force it generates pushes against the mold, thereby completing the mold installation operation.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) When the two moving square plates on the clamping drive mechanism move towards each other and connect to the side of the mold, it indicates that the mold has moved into place in the mounting box. Before installing the mold, the spring stop block is pulled outward to limit its movement within the clamping rod via the clamping plate, thus putting the clamping spring in a buffered state and causing the two spring stop blocks to move outward. When the mold moves into place, the spring stop block is released, allowing it to reset via the reset of the clamping spring, causing the two spring stop blocks to reset and enter the extension slot, thereby limiting the extension block on the extension plate and eliminating the constraint on the extension plate. When the mold is subjected to force, the spring cannot be reset due to the limiting action of the former. The elastic force of the spring pushes against the mold, making it stably installed in the mounting box, thus completing the mold installation operation. When the mold needs to be disassembled, simply pull the spring stop block outward so that the spring stop block is no longer limited by the extension block. The elastic force of the several springs resets and pops the mold out of the mounting box, thus completing the mold disassembly. This avoids the need for different types of tools to assist in disassembly and installation when changing molds, thus enabling quick mold installation and disassembly and improving molding efficiency.

[0024] (2) When the moving square plate moves, the irregular locking block contacts the self-locking inclined block, causing it to move within the self-locking square plate through the self-locking rod. This causes the self-locking spring to be in a buffer state. After the irregular locking block passes through the square locking groove, the self-locking inclined block contacts the self-locking inclined groove provided in the irregular locking block. This causes the self-locking spring to reset and move, while simultaneously driving the self-locking inclined block into the self-locking inclined groove. This causes the main magnetic sheet to contact the auxiliary magnetic sheet, energizing the electric telescopic rod and causing it to retract. This causes the auxiliary locking square rod on its output end to pass through the linkage square plate and the irregular locking block and enter the self-locking inclined block to connect with the auxiliary locking square groove. This prevents the moving square plate from moving, thereby connecting the two molds together. This prevents the pressure generated during injection molding or forming from causing them to displace or shake, thereby improving the stability during forming and improving the quality of forming.

[0025] (3) The operator uses the combination of the clamping and locking mechanism and the spring-stop locking mechanism to install the two molds on the closing square plate and the linkage block respectively. By starting the output end of the telescopic cylinder, it pushes the closing square plate to move within the positioning base through the positioning rod on the positioning block. The positioning spring is in a buffer state, which makes the two molds fit together and contact each other. The two are tightly connected together by the dynamic lock self-control component, thus forming a handle shape through the combination of the mold cavity and the mold core. The slurry is put into the mold cavity through the existing technology, thereby shaping the handle and completing the forming of the handle, improving the forming efficiency and stability.

[0026] (4) The rotational speed of the driven shaft is increased by the scraping plate unit, causing the cam to rotate rapidly. When the cam contacts the blowing plate, it moves within the limiting groove by the limiting block on the limiting plate, and the limiting spring on the limiting rod is in a buffered state. Through the movement of the limiting plate, the air contained in the cavity of the wind-driven square box enters the square moving sleeve through the circular moving groove, causing the two auxiliary blocks inside to move relative to each other. One of the auxiliary blocks blocks the through groove to prevent air from escaping, while the other auxiliary block moves within the guide groove by the guide block, and the guide spring on the guide rod is in a buffered state. Through the flow groove on the auxiliary block, the air flows out through the flow groove, and the compressed air enters the high-pressure spray head through the hose. Dry ice particles are contained in the spray head, and several dry ice particles impact the surface of the molded handle at high speed through the high-pressure spray head. The rotation of several fan blades accelerates the cooling speed of the molded handle. This process improves molding efficiency. High-speed impact of dry ice particles on the burr surface causes the dry ice to instantly shatter and sublimate, absorbing a large amount of heat. Due to the difference in thermal expansion coefficients between the burrs and the substrate, the burrs quickly crack, and the shattered dry ice particles enter the cracks. As the dry ice evaporates, its volume expands instantly, creating a miniature bomb at the impact point. This rapidly removes the burrs, achieving a good cleaning effect without affecting the molded handle, thus improving the quality of the handle production. When the cam no longer contacts the blowing plate, the limit spring resets the limit plate, causing the auxiliary block that was blocking the permeable groove to move. Another auxiliary block blocks the original outlet groove, preventing the high-pressure spray head from moving back when the limit plate resets. Simultaneously, high-pressure spraying can intermittently remove burrs from the molded handle, extending the dry ice particle usage time. Furthermore, the scraper on the blowing plate cleans up any debris that falls onto the base plate, allowing for recycling.

[0027] (5) When the moving plate moves towards the linkage block, the linkage rod on the moving plate enters the linkage sleeve on the linkage block and contacts the linkage disc, limiting its movement within the linkage sleeve. This keeps the linkage spring in a buffered state, increasing the stability of the two molds during mold closing and preventing deviations that could affect the molding quality. Simultaneously, the scraping rack moves within the linkage sleeve and engages the scraping gear. Through the phase-shifting single-clamp unit, the scraping gear on the scraping shaft can only rotate in one direction. When the two molds are ready to separate after injection molding, the linkage spring resets, causing the scraping rack to reset and engage the scraping gear, thus allowing the scraping... The large gear on the rotating shaft meshes with the small gear, and the different ratios between the two gears of different sizes make the small gear rotate faster. This causes the driving pulley on the linkage shaft to drive the driven shaft on the driven pulley to rotate via the transmission belt, which in turn causes several fan blades to rotate rapidly. The resulting airflow acts on the area after the two molds have separated, cooling the molded handle and making it easier to demold later, thus improving molding efficiency. At the same time, since a lot of odor is generated when the mold is removed after injection molding, the above-described method can disperse these odors, preventing operators from inhaling large amounts of these odors for a long time and affecting their health.

[0028] (6) When installing the mold, align it with the mounting box and press it to make it contact the drive square plate. This allows the drive rod in the drive square groove to move within a limited position, so that several compression springs are in a buffered state. When the drive square plate moves down, it drives the drive rack to move and meshes with the drive gear, causing the drive thread shaft to rotate. This causes the drive cross block to move within the guide rod through the guide cross block, so that the attached square plate on the extension plate contacts the side of the mold. The two attached square plates position the mold in the current position. When the mold shakes during the injection molding process, the extension rod on the attached square plate moves within the extension plate within a limited position, so that the attached spring is in a buffered state. The buffering force is used to offset the impact force caused by the mold shaking, thereby improving the molding quality and stability. At the same time, the extension plate is limited in the current position by the spring-locking mechanism, thus completing the mold installation operation and improving the installation efficiency.

[0029] (7) When the scraping rack moves away from the telescopic cylinder, the inclined surface of the phase moving block contacts the inclined surface of the phase moving groove, causing it to move within the brake groove by the brake plate. This keeps the phase moving spring in a buffered and reset state, preventing the scraping shaft from rotating. When the scraping rack resets and moves towards the telescopic cylinder, the phase moving block no longer contacts the inclined surface of the phase moving groove, and its right-angled surface contacts the right-angled surface of the phase moving groove. This prevents the phase moving spring from being in a buffered state and causes the scraping shaft to rotate, so that the scraping shaft can only rotate in one direction. Attached Figure Description

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] Implementation examples, by Figures 1 to 12The present invention includes a base plate 1, on which a mounting bracket 2 is mounted, and the mounting bracket 2 is bolted to a mounting plate 3; a telescopic cylinder 4 is mounted on the mounting plate 3, and the telescopic cylinder 4 is connected to a closing mechanism; the closing mechanism includes a closing square plate 5 disposed on the output end of the telescopic cylinder 4, and an irregularly shaped locking block 6 is mounted on the closing square plate 5, and the irregularly shaped locking block 6 is connected to a square locking groove 7 through a moving lock self-control component; the square locking groove 7 is connected to a linkage block 8 provided on the base plate 1; a mounting box 9 is provided on the linkage block 8 and the closing square plate 5, and the mounting box 9 is connected to the mold 1. The two molds 10 are connected by a clamping and tightening mechanism; each mold 10 has a mold cavity 11, and a mold core 12 is installed in one of the mold cavities 11; symmetrically mounted positioning blocks 13 are mounted on the moving square plate 5, each positioning block 13 has a positioning rod 14, and a positioning spring 15 is sleeved on the positioning rod 14. One end of the positioning spring 15 is fixedly connected to the positioning block 13, and the other end is fixedly connected to the positioning base 16 on the linkage block 8; the linkage block 8 has a linkage sleeve 17, and the linkage sleeve 17 and the linkage rod 18 on the moving square plate 5 are connected by a scraping plate unit.

[0047] The operator uses the clamping and locking mechanism and the spring-locking mechanism to install the two molds on the closing square plate 5 and the linkage block 8 respectively. By activating the output end of the telescopic cylinder 4, it pushes the closing square plate 5 to move within the positioning base 16 through the positioning rod 14 on the positioning block 13. The positioning spring 15 is in a buffer state, which causes the two molds to come into contact and be tightly connected by the dynamic locking self-control component. Thus, the combination of the mold cavity 11 and the mold core 12 forms a handle shape. The slurry is poured into the mold cavity 11 using existing technology to shape the handle, thus completing the handle forming and improving the forming efficiency and stability.

[0048] The scraping plate removal unit in this embodiment includes a linkage circular plate 19 disposed within a linkage sleeve 17. A scraping rack 20 is provided on the linkage circular plate 19, and the scraping rack 20 is slidably connected to the linkage sleeve 17. The inner cavity of the linkage sleeve 17 and the linkage circular plate 19 are connected by a linkage spring 21. The scraping rack 20 meshes with a scraping gear 22, and the scraping gear 22 is connected to a scraping rotating shaft 23 via a phase-shifting single-engagement unit. One end of the scraping rotating shaft 23 is connected to a scraping base 24 provided on the linkage block 8, and the other end is connected to... A large gear 25 is connected and meshes with a small gear 26. A linkage shaft 27 is mounted on the small gear 26. One end of the linkage shaft 27 is connected to the scraping base 24, and the other end is connected to the driving pulley 28. The driving pulley 28 is connected to the driven pulley 30 through the transmission belt 29. A driven shaft 31 is mounted on the driven pulley 30. One end of the driven shaft 31 is connected to several fan blades 32, and the other end passes through the driven base 33 on the base plate 1 and is connected to the cam 34. The cam 34 is connected to the blowing and crushing assembly.

[0049] When the moving plate 5 moves toward the linkage block 8, the linkage rod 18 on the moving plate 5 enters the linkage sleeve 17 on the linkage block 8 and contacts the linkage circular plate 19, limiting its movement within the linkage sleeve 17. This keeps the linkage spring 21 in a buffered state, increasing the stability of the two molds during mold closing and preventing deviations that could affect the molding quality. Simultaneously, the scraping rack 20 moves within the linkage sleeve 17 and engages the scraping gear 22. Through the phase-shifting single-clamp unit, the scraping gear 22 on the scraping shaft 23 can only rotate in one direction. When the two molds are ready to separate after injection molding, the linkage spring 21 resets, causing the scraping rack 20 to reset and move, engaging the scraping gear 22 to rotate. This causes the large gear 25 on the scraping shaft 23 to mesh with the small gear 26 and rotate. Due to the different ratio between the two gears of different sizes, the small gear 26 rotates faster, causing the driving pulley 28 on the linkage shaft 27 to drive the driven shaft 31 on the driven pulley 30 to rotate via the transmission belt 29. This causes several fan blades 32 to rotate rapidly, and the resulting airflow acts on the area after the two molds have left, cooling the molded handle and making it easier to demold later, thereby improving molding efficiency. At the same time, since a lot of odor is generated when the mold leaves after injection molding, the above-described method can disperse these odors, preventing operators from inhaling large amounts of these odors during long-term work and affecting their health.

[0050] The automatic locking component of this embodiment includes a self-locking inclined block 35 that is connected to and cooperates with the irregularly shaped locking block 6. Self-locking rods 36 are symmetrically mounted on the self-locking inclined block 35. The self-locking rods 36 pass through a self-locking square plate 37 provided inside the linkage block 8 and are connected to a self-locking round plate 38. A self-locking spring 39 is sleeved on the self-locking rod 36. One end of the self-locking spring 39 is connected to the self-locking round plate 38, and the other end is connected to the self-locking square plate 37. The self-locking inclined block 35 and the irregularly shaped locking block 6... The locking self-sloping groove 40 is provided for connection and arrangement. The main magnetic plate 41 is installed in the locking self-sloping groove 40. The main magnetic plate 41 is connected to the auxiliary magnetic plate 42 provided on the locking self-sloping block 35. The contact between the two is connected to the electric telescopic rod 43 provided on the linkage block 8. The output end of the electric telescopic rod 43 is equipped with an auxiliary locking rod 44. The auxiliary locking rod 44 passes through the linkage block 8 and the irregular lock block 6 and is connected to the auxiliary locking groove 45 provided in the locking self-sloping block 35.

[0051] When the moving square plate 5 moves, the irregularly shaped locking block 6 contacts the self-locking inclined block 35, causing it to move within the self-locking square plate 37 via the self-locking rod 36. This keeps the self-locking spring 39 in a buffered state. After the irregularly shaped locking block 6 passes through the square locking groove 7, the self-locking inclined block 35 contacts the self-locking inclined groove 40 provided within the irregularly shaped locking block 6. This causes the self-locking spring 39 to reset and move, simultaneously driving the self-locking inclined block 35 into the self-locking inclined groove 40. This brings the main magnetic plate 41 into contact with the auxiliary magnetic plate 42, energizing the electric telescopic rod 43 and causing it to retract. The auxiliary locking square rod 44 on its output end passes through the linkage block 8 and the irregularly shaped locking block 6 and enters the self-locking inclined block 35, connecting with the auxiliary locking square groove 45. This prevents the moving square plate 5 from moving, thus connecting the two molds 10 together. This avoids displacement or shaking caused by the pressure generated during injection molding or molding, thereby improving the stability during molding and enhancing the molding quality.

[0052] The blowing crushing assembly of this embodiment includes a blowing square plate 46 connected to and cooperating with a cam 34, and a scraper 47 mounted on the blowing square plate 46. The blowing square plate 46 and a limiting plate 48 are connected by a connecting rod. Limiting blocks 49 are symmetrically mounted on the limiting plate 48. The limiting blocks 49 are connected to a limiting groove 51 provided in the pneumatic square box 50. A limiting rod 52 is installed in the limiting groove 51. A limiting spring 53 is sleeved on the limiting rod 52. One end of the limiting spring 53 is fixedly connected to the limiting groove 51, and the other end is fixedly connected to the limiting block 49. The pneumatic square box 50 and the driven base 33 are connected by a pneumatic base 54. A circular moving passage is provided in the cavity inside the pneumatic square box 50. The circular moving channel 55 is connected to the square moving sleeve 56 provided on the wind-driven square box 50. The square moving sleeve 56 is provided with an auxiliary moving block 57. Guide blocks 58 are symmetrically installed on the auxiliary moving block 57. The guide blocks 58 are slidably connected to the guide groove 59 provided in the square moving sleeve 56. A guide rod 60 is fixedly installed in the guide groove 59. A guide spring 61 is sleeved on the guide rod 60. One end of the guide spring 61 is fixedly connected to the guide groove 59, and the other end is fixedly connected to the guide block 58. The auxiliary moving block 57 is symmetrically provided with a flow channel 62. The flow channel 62 is connected to the permeable channel 63 provided in the square moving sleeve 56. The permeable channel 63 is connected to the high-pressure sprinkler head 64 through a hose 65.

[0053] The scraping plate unit increases the rotational speed of the driven shaft 31, causing the cam 34 to rotate rapidly. When the cam 34 contacts the blowing plate 46, it is limited in its movement within the limiting groove 51 by the limiting block 49 on the limiting plate 48. This keeps the limiting spring 53 on the limiting rod 52 in a buffered state. The movement of the limiting plate 48 allows the air contained in the cavity of the pneumatic box 50 to enter the square moving sleeve 56 through the circular moving groove 55, causing the two auxiliary moving blocks 57 inside to move relative to each other. The auxiliary block 57 blocks the through groove 63 to prevent air from escaping, while another auxiliary block 57 moves within the guide groove 59 via the guide block 58, causing the guide spring 61 on the guide rod 60 to be in a buffered state. Air flows out through the flow groove 62 on the auxiliary block 57, allowing compressed air to enter the high-pressure spray head 64 through the hose 65. The high-pressure spray head 64 contains dry ice particles, which impact the surface of the molded handle at high speed. The rotation of the fan blades 32 accelerates the cooling of the molded handle, improving molding efficiency. Simultaneously, the high-speed impact of the dry ice particles on the burr surface causes the dry ice to instantly shatter and sublimate, absorbing a large amount of heat. Due to the difference in thermal expansion coefficients between the burrs and the substrate, the burrs quickly crack, and the shattered dry ice particles enter the cracks. Due to the evaporation of the dry ice, its volume expands instantaneously, creating micro-explosives at the impact point. This rapidly removes the burrs, achieving a good cleaning effect without affecting the molded handle, thus improving the quality of the handle production. When the cam 34 no longer contacts the blower... When the square plate 46 is moved, the limit plate 48 is reset by the reset of the limit spring 53, which causes the auxiliary moving block 57, which originally blocked the through groove 63, to move. Another auxiliary moving block 57 blocks the original outlet groove, thus preventing the high-pressure spray head 64 from moving back when the limit plate 48 is reset. At the same time, the formed handle can be intermittently sprayed with high pressure to remove burrs, which increases the usage time of dry ice particles. Meanwhile, the scraper 47 installed on the square plate 46 can clean up the debris that falls on the base plate 1, so that it can be recycled and reused.

[0054] The clamping and engaging mechanism of this embodiment includes a drive square groove 66 disposed within the mounting box 9. The drive square groove 66 is slidably connected to a drive square plate 67, and the drive square plate 67 is connected to a drive rod 68 disposed within the drive square groove 66. The inner bottom surface of the mounting box 9 is connected to the drive square plate 67 by a plurality of compression springs 69. A drive rack 70 is mounted on the drive square plate 67, and the drive rack 70 meshes with a drive gear 71. A drive threaded shaft 72 is mounted on the drive gear 71, and the drive threaded shaft 72 is connected to the mounting box 9 in a transmission manner. A drive cross block 73 is threadedly mounted on the drive threaded shaft 72. A directional horizontal block 74 is installed on one side of the driving horizontal block 73. The directional horizontal block 74 is connected to the directional rod 75 provided on the mounting box 9. An extension plate 76 is installed on the other side. An extension connecting block 77 is provided on the extension plate 76. An extension slot 78 is provided on the extension connecting block 77. The extension slot 78 is connected to the spring-loaded locking mechanism. Extension rods 79 are symmetrically installed on the extension plate 76. The two extension rods 79 are connected to the moving square plate 80. A moving spring 81 is sleeved on the extension rod 79. One end of the moving spring 81 is connected to the moving square plate 80, and the other end is connected to the extension plate 76.

[0055] When installing mold 10, it is aligned with the mounting box 9 and pressed down to contact the drive square plate 67. This causes the drive square plate 67 to move within the drive rod 68 located in the drive square groove 66, thus limiting the movement of the compression springs 69. When the drive square plate 67 moves downward, it drives the drive rack 70 to move and engage the drive gear 71, causing the drive threaded shaft 72 to rotate. This causes the drive cross block 73 to move within the guide rod 75 via the guide cross block 74, thus causing the moving square plate 80 on the extension plate 76 to contact the side of mold 10. The mold 10 is positioned in its current position by two abutting square plates 80. When the mold 10 shakes during the injection molding process, the extension rod 79 on the abutting square plate 80 moves within the extension plate 76 to limit its movement, so that the abutting spring 81 is in a buffer state. The buffering force generated by this spring counteracts the impact force of the mold 10 shaking, thereby improving the molding quality and stability. At the same time, the extension plate 76 is limited in its current position by the cooperation of the spring-locking mechanism, thereby completing the installation operation of the mold 10 and improving the installation efficiency.

[0056] The phase-moving single-combination unit of this embodiment includes a plurality of phase-moving slots 82 disposed on the scraping rotating shaft 23. A phase-moving spring 83 is installed on the phase-moving slot 82. The phase-moving spring 83 is fixedly connected to the phase-moving inclined block 84. A brake plate 85 is installed on the phase-moving inclined block 84. The brake plate 85 is slidably connected to the brake groove 86 provided in the phase-moving slot 82. The phase-moving inclined block 84 is connected to a plurality of phase-moving inclined slots 87 provided in the scraping gear 22.

[0057] When the scraping rack 20 moves away from the telescopic cylinder 4, the inclined surface of the phase-moving inclined block 84 contacts the inclined surface of the phase-moving inclined groove 87, causing it to move within the brake groove 86 via the brake plate 85. This keeps the phase-moving spring 83 in a buffered and reset state, preventing the scraping shaft 23 from driving the scraping gear 22 to rotate. When the scraping rack 20 resets and moves towards the telescopic cylinder 4, the phase-moving inclined block 84 no longer contacts the inclined surface of the phase-moving inclined groove 87, and its right-angled surface contacts the right-angled surface of the phase-moving inclined groove 87. This prevents the phase-moving spring 83 from being in a buffered state and causes the scraping shaft 23 to rotate, so that the scraping shaft 23 can only rotate in one direction.

[0058] The spring-locking mechanism of this embodiment includes a spring-locking square plate 88 that is connected to the extension slot 78. Two spring-locking square plates 88 are connected to a spring-locking block 89. Actuating plates 90 are symmetrically installed on the spring-locking block 89. Actuating rods 91 are provided on the actuating plates 90. One end of the actuating rods 91 is fixedly connected to the closing square plate 5, and the other end is fixedly connected to the spring-locking round plate 92. Actuating springs 93 are sleeved on the actuating rods 91. One end of the actuating springs 93 is fixedly connected to the spring-locking round plate 92, and the other end is fixedly connected to the actuating plate 90.

[0059] When the two abutting square plates 80 on the clamping drive mechanism move towards each other and connect to the side of the mold 10, it indicates that the mold 10 has moved into place within the mounting box 9. Before installing the mold 10, the spring stop block 89 is pulled outward, causing it to move within the abutting rod 91 via the abutting plate 90, thus putting the abutting spring 93 in a buffered state and causing the two spring stop plates 88 to move outward. When the mold 10 is in place, the spring stop block 89 is released, causing it to reset via the reset of the abutting spring 93, which in turn causes the two spring stop plates 88 to reset and move into the extension slot 78, thereby limiting the extension connecting block 77 on the extension plate 76 and rendering it unusable. When force is applied to the mold 10, the spring 93 cannot return to its original position due to the limiting action of the former. The elastic force exerted by the spring 93 pushes the mold 10, making it stably installed in the mounting box 9, thus completing the installation operation of the mold 10. When the mold 10 needs to be disassembled, simply pull the spring stop block 89 outward, so that the spring stop plate 88 no longer limits the extension block 77. The elastic force of the springs 93 returning to their original position will pop the mold 10 out of the mounting box 9, thus completing the disassembly of the mold 10. This avoids the need for different types of tools to assist in disassembly and installation when changing the mold 10, thus enabling quick installation and disassembly of the mold 10 and improving molding efficiency.

[0060] The present invention also provides a handle molding process, comprising the following steps:

[0061] Step 1: Align the mold 10 with the mounting box 9 so that it contacts the drive plate 67 and moves within the drive rod 68 in the drive groove 66, so that the compression springs 69 are in a buffered state.

[0062] Step 2: When the driving square plate 67 moves down, it drives the driving rack 70 to move and meshes with the driving gear 71, causing the driving threaded shaft 72 to rotate, which in turn causes the driving cross block 73 to move within the directional rod 75 through the directional cross block 74.

[0063] Step 3: Make the moving square plate 80 on the extension plate 76 contact the side of the mold 10, and position the mold 10 in the current position through the two moving square plates 80.

[0064] Step 4: When the two moving square plates 80 on the clamping and tightening mechanism move towards each other and connect to the side of the mold 10, it indicates that the mold 10 has moved into place in the mounting box 9. By releasing the spring stop block 89, it moves by the reset of the engaging spring 93.

[0065] Step 5: The spring force generated by the resetting spring 93 drives the two spring stop plates 88 to reset and move into the extension slot 78, thereby limiting the extension block 77 on the extension plate 76.

[0066] Step 6: When the force applied to the mold 10 is lost, the spring 93 cannot return to its original position due to the limiting of the extension block 77, so that the elastic force it generates pushes against the mold 10, thereby completing the installation operation of the mold 10.
