Description

Technical Field

[0001] This invention relates to the field of molding machine technology, and in particular to a stamping molding machine for luggage and case components. Background Technology

[0002] Bags and suitcases are essential travel items used to carry clothing and other belongings, making them easy to carry and providing protection. The outer shells of conventional bags and suitcases are often made of materials like PC and ABS through vacuum forming. This vacuum forming method requires high tensile and ductile properties of the material, making it more suitable for single-component materials or composite boards with high tensile and ductile properties. As the homogenization of bags becomes increasingly serious, people are seeking more differentiated designs. For example, using different textures on the outer surface of a bag can effectively create a differentiated design.

[0003] Chinese invention patent announcement number CN118438645A discloses a stamping and forming equipment and process for bags and suitcases. Bags and suitcases are essential travel items used to hold clothing and other belongings, facilitating carrying and providing protection. Conventional bags and suitcases are often made of materials like PC and ABS through vacuum forming. This vacuum forming method requires high tensile and ductile properties of the material, making it more suitable for single-component materials or composite boards with high tensile and ductile properties. With increasing homogenization of bags and suitcases, people are increasingly seeking differentiated designs. For example, different textures on the outer surface of the bag can effectively create a differentiated design.

[0004] There are still some problems with the molding machine during use. Traditional stamping of plastic bag surface parts often involves manually placing the parts on the lower die base, relying solely on a simple limiting structure for rough positioning. Lacking dedicated adjustment and lifting components, the positional accuracy of the parts is difficult to control precisely. During the stamping process, no stable clamping structure is set on both sides of the parts, making them susceptible to movement, displacement, and warping under the stamping pressure. This directly leads to problems such as burrs on the stamping edges, dimensional deviations, and forming defects, resulting in a low yield rate. Summary of the Invention

[0005] The purpose of this application is to provide a stamping forming machine for bag and case body components, which realizes the adjustment of the position of plastic bag and case parts on the lower die base by adjusting the components and lifting the components, then pressing the two sides of the plastic bag and case parts by pressing the components by pressing the components by pressing the upper die base, and finally stamping the surface of the plastic bag and case parts on the lower die base by pressing the upper die base.

[0013] Preferably, the pressing assembly includes a second cylinder fixedly mounted on the frame, the bottom end of the second cylinder being fixedly connected to a bracket, a pair of sleeves being fixedly connected to one side of the bracket, the other end of the pair of sleeves being slidably connected to a guide rod, the top end of the guide rod being fixedly connected to a first bearing, and the first bearing being fixedly connected to one side of the frame.

The two ends of the spring are fixedly connected to the bottom surface of the collar and the top surface of the limiting block, respectively.

[0016] In summary, the present invention has the following beneficial effects: 1. The present invention has a reasonable structure. When adjusting the front and rear positions of the frame, the turntable is rotated. The turntable is fixedly connected to one end of the first threaded rod. The rotation of the turntable drives the first threaded rod to rotate. A first sleeve is threadedly connected to the first threaded rod, and the first sleeve is fixedly connected to the second horizontal plate. The rotation of the first threaded rod drives the second horizontal plate to move through the first sleeve. The movement of the second horizontal plate is achieved by the slider on the first horizontal plate sliding on the slide rail, thereby facilitating the adjustment of the frame position.

[0017] 2. In this invention, when adjusting the height of the stage, the servo motor on the second horizontal plate operates, causing the second threaded rod to rotate. A second sleeve is threaded onto the second threaded rod and fixedly connected to the connector. The rotation of the second threaded rod drives the connector to move through the second sleeve. The movement of the connector causes the sleeve block to slide on the slide rod through the docking post, increasing the stability of the sleeve block's movement. The movement of the sleeve block pushes the stage on the hinge plate upward through the push plate on the side rod. The upward movement of the stage causes the driven plate to move upward, increasing the stability of the stage's movement.

[0018] 3. In this invention, the component is placed on the lower mold base, and then the second cylinder pushes the bracket to move. The movement of the bracket causes the arm plate on the rod to move downward, so that the pressure roller can fit against both ends of the component and the arm plate can rotate on the rod. The gripper on the rod pulls the limiting block to slide on the positioning rod through the docking plate on the sleeve, so that the limiting block can pull the spring. The spring force makes the pressure roller fit tightly against both ends of the component on the lower mold base for fixing, thus preventing the upper mold base from shifting when stamping the surface of the component on the lower mold base.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1 - Figure 7 The stamping forming machine for a luggage body component shown includes a forming machine body 1, a frame 101 fixedly installed on the top surface of the forming machine body 1, a control panel 102 fixedly installed on the surface of the frame 101, a first cylinder 103 fixedly installed on the frame 101, a base plate 104 fixedly connected to the bottom end of the first cylinder 103, an upper mold base 105 provided on the bottom surface of the base plate 104, and a lower mold base 106 provided directly below the upper mold base 105; it also includes an adjustment component, a lifting component, and a pressing component.

[0024] Specifically, it should be noted that the servo motor 3 is electrically connected to the control panel 102 via wires. The specific working principle between them is based on existing technology and will not be elaborated on here.

[0025] In one embodiment of this invention, the adjusting component includes a pair of slide rails 2 fixedly mounted on the molding machine body 1. A slider 201 is slidably connected to the pair of slide rails 2. The slider 201 is fixedly connected to the bottom surface of the first horizontal plate 202. The first horizontal plate 202 is fixedly connected to the bottom surface of the frame 203. A second horizontal plate 204 is fixedly connected to the middle of the bottom surface of the frame 203. A first sleeve 205 is fixedly connected to the middle of the bottom surface of the second horizontal plate 204. The first sleeve 205 is threadedly connected to the first screw... On the threaded rod 206, one end of the first threaded rod 206 is rotatably connected to the frame 101, and the other end of the first threaded rod 206 is fixedly connected to the turntable 207. A driven plate 208 is provided on the inner wall of the frame 203. A pair of sliding grooves 209 are provided on the driven plate 208. A pin 210 is slidably connected inside the pair of sliding grooves 209. The pin 210 is fixedly connected to the inner wall of the frame 203. A platform 211 is fixedly installed at the top of the driven plate 208. A lower mold base 106 is provided on the platform 211.

[0026] Specifically, when adjusting the front and rear positions of the frame 203, the turntable 207 is rotated. The turntable 207 is fixedly connected to one end of the first threaded rod 206. The rotation of the turntable 207 drives the first threaded rod 206 to rotate. A first sleeve 205 is threadedly connected to the first threaded rod 206, and the first sleeve 205 is fixedly connected to the second horizontal plate 204. The rotation of the first threaded rod 206 drives the second horizontal plate 204 to move through the first sleeve 205. The movement of the second horizontal plate 204 is achieved by the slider 201 on the first horizontal plate 202 sliding on the slide rail 2, thereby facilitating the adjustment of the position of the frame 203.

[0027] As one embodiment of this invention, the lifting assembly includes a servo motor 3 fixedly installed at the center of the top surface of the second horizontal plate 204. The output end of the servo motor 3 is fixedly connected to a second threaded rod 301. The other end of the second threaded rod 301 is rotatably connected to the frame 203. A second sleeve 302 is threadedly connected to the second threaded rod 301. The second sleeve 302 is fixedly installed at the center of the bottom surface of the connector 303. Both ends of the connector 303 are fixedly connected to the docking post 304. The docking post 304 is fixedly connected to one side of the sleeve block 305. The sleeve block 305 is slidably connected to the slide rod 306. Both ends of the slide rod 306 are fixedly connected to the frame 203. A side rod 307 is fixedly connected to the other side of the sleeve block 305. A push plate 308 is rotatably connected to the other end of the side rod 307. The top end of the push plate 308 is rotatably connected to the hinge plate 309. The hinge plate 309 is fixedly installed at the bottom surface of the platform 211.

[0028] Specifically, when adjusting the height of the stage 211, the servo motor 3 on the second horizontal plate 204 operates, causing the second threaded rod 301 to rotate. A second sleeve 302 is threaded onto the second threaded rod 301 and is fixedly connected to the connector 303. The rotation of the second threaded rod 301 drives the connector 303 to move through the second sleeve 302. The movement of the connector 303 causes the sleeve block 305 to slide on the slide rod 306 through the docking post 304, increasing the stability of the movement of the sleeve block 305. The movement of the sleeve block 305 pushes the stage 211 on the hinge plate 309 upward through the push plate 308 on the side rod 307. The upward movement of the stage 211 drives the driven plate 208 to move upward, increasing the stability of the movement of the stage 211.

[0029] In one embodiment of this invention, the pressing assembly includes a second cylinder 4 fixedly mounted on the frame 101. The bottom end of the second cylinder 4 is fixedly connected to the bracket 401. A pair of sleeve plates 402 are fixedly connected to one side of the bracket 401, and the other ends of the pair of sleeve plates 402 are slidably connected to the guide rod 403. The top end of the guide rod 403 is fixedly connected to the first bearing seat 404, which is fixedly connected to one side of the frame 101. Rods 405 are fixedly connected to both ends of the bracket 401, and a pair of arm plates 406 are rotatably connected to the rods 405. A pressure roller 407 is rotatably connected to the other end of the pair of arm plates 406, and the pressure roller 407 is in contact with the top surface of the lower mold base 106. The arm plate 406 is fixedly connected to one side of a sleeve 408, which is rotatably connected to the rod body 405. The other end of the sleeve 408 is fixedly connected to a docking plate 409, and a linkage plate 410 is rotatably connected to the docking plate 409. The other end of the linkage plate 410 is connected to a limiting block 411, which is slidably connected to a positioning rod 412. The bottom end of the positioning rod 412 is fixedly connected to a second bearing 413, which is fixedly connected to a bracket 401. The top end of the positioning rod 412 is fixedly connected to a collar 414, and a spring 415 is sleeved on the positioning rod 412. The two ends of the spring 415 are fixedly connected to the bottom surface of the collar 414 and the top surface of the limiting block 411, respectively.

[0030] Specifically, the component is placed on the lower die base 106, and then the second cylinder 4 pushes the bracket 401 to move. The movement of the bracket 401 causes the arm plate 406 on the rod 405 to move downward, so that the pressure roller 407 can fit against both ends of the component and the arm plate 406 can rotate on the rod 405. The gripping of the rod 405 pulls the limiting block 411 to slide on the positioning rod 412 through the docking plate 409 on the sleeve 408, so that the limiting block 411 can pull the spring 415. The elastic force of the spring 415 makes the pressure roller 407 fit tightly against both ends of the component on the lower die base 106 for fixing, so as to prevent the upper die base 105 from shifting when stamping the surface of the component on the lower die base 106.

[0031] The working principle of this invention is as follows: When adjusting the front and rear positions of the frame 203, the turntable 207 is rotated. The turntable 207 is fixedly connected to one end of the first threaded rod 206. The rotation of the turntable 207 drives the first threaded rod 206 to rotate. A first sleeve 205 is threadedly connected to the first threaded rod 206, and the first sleeve 205 is fixedly connected to the second horizontal plate 204. The rotation of the first threaded rod 206 drives the second horizontal plate 204 to move through the first sleeve 205. The movement of the second horizontal plate 204 is achieved by the slider 201 on the first horizontal plate 202 sliding on the slide rail 2, thereby facilitating the adjustment of the position of the frame 203.

[0032] When adjusting the height of the stage 211, the servo motor 3 on the second horizontal plate 204 operates, causing the second threaded rod 301 to rotate. A second sleeve 302 is threaded onto the second threaded rod 301 and is fixedly connected to the connector 303. The rotation of the second threaded rod 301 drives the connector 303 to move through the second sleeve 302. The movement of the connector 303 causes the sleeve block 305 to slide on the slide rod 306 through the docking post 304, increasing the stability of the movement of the sleeve block 305. The movement of the sleeve block 305 pushes the stage 211 on the hinge plate 309 upward through the push plate 308 on the side rod 307. The upward movement of the stage 211 drives the driven plate 208 to move upward, increasing the stability of the movement of the stage 211.

[0033] The component is placed on the lower die base 106, and then the second cylinder 4 pushes the bracket 401 to move. The movement of the bracket 401 causes the arm plate 406 on the rod 405 to move downward, so that the pressure roller 407 can fit against both ends of the component and the arm plate 406 can rotate on the rod 405. The gripping of the rod 405 pulls the limiting block 411 to slide on the positioning rod 412 through the docking plate 409 on the sleeve 408, so that the limiting block 411 can pull the spring 415. The elastic force of the spring 415 makes the pressure roller 407 fit tightly against both ends of the component on the lower die base 106 for fixing, so as to prevent the upper die base 105 from shifting when stamping the surface of the component on the lower die base 106.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
