[0062] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0063] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0064] In order to further explain the technical means and effects adopted by the present application to achieve the intended purpose, the present application is described in detail below in conjunction with the accompanying drawings and preferred implementation methods.
[0065] See also Figure 1 The plate extrusion molding device 100 provided in the embodiment of the present application comprises a bottom die 10, a pressing block module 30 and a pressing plate module 50. The bottom die 10 is used to carry the plate 200 to be extruded and shape one side of the plate 200, and the pressing block module 30 is used to extrude the plate 200 onto the bottom die 10 from the other side of the plate 200 and shape the other side of the plate 200. The pressing plate module 50 is used to press the pressing block module 30 from the side of the pressing block module 30 away from the bottom die 10 to provide a force for extruding the plate 200.
[0066] See also Figure 2 The bottom mold 10 is provided with a forming groove 11, which is surrounded by a bottom wall 111 and a plurality of groove walls 113, and a corner 115 is formed between two adjacent groove walls 113. Specifically, the forming groove 11 is used to shape one side of the plate 200. When the plate 200 is pressed toward the bottom mold 10, as the pressure increases, the plate 200 will be squeezed into the forming groove 11 and abut against the bottom wall 111 and the groove wall 113, thereby completing the shaping of one side. In this embodiment, the groove wall 113 is arranged perpendicular to the bottom wall 111, and four groove walls 113 surround the bottom wall 111, thereby forming a cubic forming groove 11. The corner 115 is formed between two adjacent groove walls 113, and is used for smooth transition between the two groove walls 113. The corner 115 can be an arc-shaped side wall perpendicular to the bottom wall 111, or a side wall that is not perpendicular to the bottom wall 111 and has a certain angle with the bottom wall 111, and the present application does not limit this. In other embodiments, the groove wall 113 may not be perpendicular to the bottom wall 111, and two adjacent groove walls 113 may be directly connected to form perpendicular right-angled surfaces. The present application does not limit the specific structure of the groove wall 113. According to the requirements for the shape of the plate 200 when it is finally formed, the plurality of groove walls 113 may be correspondingly set to structures with different numbers, different lengths, and different shapes from those in the present embodiment.
[0067] Please also read Figure 1 and Figure 3The pressing block module 30 includes a limiting substrate 31, a plurality of first pressing blocks 33, a plurality of first springs 34, a plurality of second pressing blocks 35 and a plurality of second springs 36. The first pressing blocks 33 and the second pressing blocks 35 are movably arranged on the limiting substrate 31, and one second pressing block 35 is adjacent to two first pressing blocks 33. The pressing block module 30 is arranged corresponding to the bottom mold 10, wherein the limiting substrate 31 corresponds to the bottom wall 111 of the forming groove 11, the first pressing block 33 corresponds to a groove wall 113 of the forming groove 11, and each second pressing block 35 corresponds to a corner 115. When being squeezed, the first pressing block 33 moves toward the bottom wall 111 and the groove wall 113, thereby squeezing the plate 200 onto the bottom wall 111 and the groove wall 113, and completing the extrusion molding of the plate 200 corresponding to the groove wall 113. The second pressing block 35 moves toward the bottom wall 111 and the corner 115 when being pressed, so as to press the plate 200 onto the bottom wall 111 and the corner 115 , thereby completing the extrusion molding of the plate 200 at the position corresponding to the corner 115 .
[0068] The limiting substrate 31 includes a bottom plate 311, and each side wall of the bottom plate 311 is formed with a first inclined surface 312, and the corner between two adjacent first inclined surfaces 312 is connected by a second inclined surface 314. Each first pressing block 33 is at least partially disposed on the first inclined surface 312, and slides along the first inclined surface 312 when being squeezed. Specifically, the limiting substrate 31 corresponds to the shape of the molding groove 11 on the bottom mold 10, that is, the first inclined surface 312 corresponds to the groove wall 113 of the molding groove 11, so that the first pressing block 33 placed corresponding to the first inclined surface 312 corresponds to the bottom wall 111; the second inclined surface 314 is arranged corresponding to the corner 115 of the molding groove 11, so that the second pressing block 35 placed corresponding to the second inclined surface 314 corresponds to the corner 115.
[0069] Please also read Figure 3 and Figure 4At least one limiting column 333 is provided on the first pressing block 33, and a plurality of limiting parts 313 are provided on the bottom plate 311. Each limiting part 313 is provided with a limiting guide hole 3131. A limiting column 333 is clamped in a limiting guide hole 3131. The limiting part 313 is used to guide the first pressing block 33 to slide along the extension direction of the limiting guide hole 3131. Specifically, the limiting guide hole 3131 is a long through hole. The width of the limiting guide hole 3131 is the same as the width of the limiting column 333. The extension direction of the limiting guide hole 3131 is parallel to the first inclined surface 312, so that when the first pressing block 33 slides along the extension direction of the limiting guide hole 3131, it maintains a state of contact with the first inclined surface 312, thereby improving the sliding stability of the first pressing block 33. The limiting guide hole 3131 is also used to limit the position of the first pressure block 33 in the sliding direction. Specifically, when the first pressure block 33 slides to a certain position along the extending direction of the limiting guide hole 3131, the limiting column 333 on the first pressure block 33 abuts against the hole wall of the limiting guide hole 3131, thereby stopping sliding.
[0070] Please also read Figure 4 and Figure 5 The first pressing block 33 further includes a first protrusion 331, which is protruded toward the direction in which the first pressing block 33 moves when pressed. Specifically, the first protrusion 331 is protruded at one end of the first pressing block 33. When the first pressing block 33 is pressed and slid, the first protrusion 331 moves to align with the connection between the bottom wall 111 and the groove wall 113 of the forming groove 11, thereby abutting the plate 200 against the position of the connection and bending it into shape. The first protrusion 331 is also used to press the plate 200 to be thinner, so that the thickness of the bent portion of the plate 200 is less than the thickness of the unbent position, thereby avoiding the stress concentration at the bent position during the bending process, which causes the plate 200 to break.
[0071] Please also read Figure 3 and Figure 5 The pressing block module 30 further includes a plurality of first springs 34, which are disposed between the first pressing block 33 and the bottom plate 311, and are used to reset the first pressing block 33 that has moved after being pressed, and to push the first pressing block 33 to its initial position when not pressed. In this embodiment, one first pressing block 33 corresponds to two first springs 34. In other embodiments, one first pressing block 33 may also correspond to one first spring 34 or three or more first springs 34, and this application does not limit this.
[0072] Please also read Figure 3 and Figure 6, a second pressing block 35 is at least partially disposed on a second inclined surface 314, and slides on the second inclined surface 314 when being squeezed. A limiting convex strip 315 is disposed on the second inclined surface 314, and a limiting groove 353 is provided on the second pressing block 35. The limiting convex strip 315 is clamped in the limiting groove 353, and is used to guide the second pressing block 35 to move along the direction in which the limiting convex strip 315 extends. Specifically, the limiting convex strip 315 is a long strip structure convexly disposed on the second inclined surface 314, and the width of the limiting convex strip 315 on the side close to the second inclined surface 314 is smaller than the width of the side away from the second inclined surface 314, and the limiting groove 353 on the second pressing block 35 matches the shape of the limiting convex strip 315, that is, when the second pressing block 35 is clamped on the limiting convex strip 315, the position of the second pressing block 35 in the direction perpendicular to the second inclined surface 314 is limited by the limiting convex strip 315.
[0073] See also Figure 7 The second pressing block 35 further includes a second protrusion 351, which is protruding from one end of the second pressing block 35 and is arranged in the direction in which the second pressing block 35 moves when being pressed. Specifically, when the second pressing block 35 is pressed and slid, the second protrusion 351 moves to align with the connection between the bottom wall 111 of the forming groove 11 and the corner 115, so that the plate 200 is abutted against the position of the connection and bent into shape. The second protrusion 351 is also used to press the plate 200 to be thinner, so that the thickness of the bent portion of the plate 200 is less than the thickness of the unbent position, thereby avoiding the stress concentration at the bent position during the bending process, which causes the plate 200 to break.
[0074] Please also read Figure 3 and Figure 7 The pressing block module 30 further includes a plurality of second springs 36, which are disposed between the second pressing block 35 and the bottom plate 311, and are used to reset the second pressing block 35 that has moved after being pressed, and to abut the second pressing block 35 to its initial position when not pressed. In this embodiment, one second pressing block 35 corresponds to one second spring 36. In other embodiments, one first pressing block 33 may also correspond to multiple second springs 36, and this application does not limit this.
[0075] See also Figure 8 The pressing plate module 50 includes a first pressing plate 51, a second pressing plate 53 and a plurality of third springs 55. The first pressing plate 51 is used to press the first pressing block 33 toward the bottom wall 111 and the groove wall 113, and the second pressing plate 53 is used to press the second pressing block 35 toward the bottom wall 111 and the corner 115. The first pressing plate 51 is arranged on a side close to the pressing block module 30, and the second pressing plate 53 is arranged on a side of the first pressing plate 51 away from the pressing block module 30. The third spring 55 is arranged between the first pressing plate 51 and the second pressing plate 53 to resist the first pressing plate 51 and the second pressing plate 53.
[0076] The first pressing plate 51 is provided with a plurality of through holes 511, and the second pressing plate 53 is provided with a plurality of extrusion heads 531, each of which is provided corresponding to a through hole 511, and is used to pass through the through hole 511 to extrude a second pressing block 35. Specifically, by providing the extrusion head 531 on the second pressing plate 53, the second pressing block 35 can be extruded through the through hole 511 on the first pressing plate 51, and by providing a plurality of third springs 55 to elastically connect the first pressing plate 51 and the second pressing plate 53, the first pressing plate 51 and the second pressing plate 53 can respectively extrude the first pressing block 33 and the second pressing block 35, and the first pressing plate 51 can be driven to move by only applying pressure to the second pressing plate 53.
[0077] The working process of the plate extrusion forming device 100 provided in the embodiment of the present application is described in detail below in combination with the extrusion process of the plate 200.
[0078] Please also read Fig. 9 and Fig.10 In this embodiment, the plate 200 after extrusion molding is a quadrilateral groove structure, and a bending portion 201 is formed between the bottom wall and the side wall of the plate 200. In order to avoid the stress of the plate 200 being concentrated at the bending portion 201 during the extrusion molding process, which may cause the plate 200 to break, the bending portion 201 needs to be processed to a thickness smaller than that of other positions during the extrusion process. In other embodiments, according to actual needs, the plate 200 may also be in other shapes, and this application does not limit this.
[0079] Please also read Figure 1 and Fig.11 In this embodiment, when pressure is applied to the pressure plate mold assembly 50, the second pressure plate 53 first drives the first pressure plate 51 to move, so that the first pressure plate 51 first contacts the first pressure block 33 and begins to squeeze the first pressure block 33. The first pressure block 33 squeezes the plate 200 to move toward the bottom wall 111 and the groove wall 113, so that it is squeezed and formed by the bottom mold 10 and the first pressure block 33. During the extrusion process, the first protrusion 331 squeezes the plate 200, so that the thickness of the position of the bending portion 201 formed by the extrusion is lower than the thickness of other positions of the plate 200, thereby avoiding the stress inside the plate 200 from being concentrated at the position of the bending portion 201. After the portion of the plate 200 corresponding to the first pressure block 33 and the groove wall 113 is extruded and formed, the position of the first pressure block 33 is fixed by the limiting portion 313 and the limiting column 333, so that the position of the first pressure plate 51 is also fixed.
[0080] Please also read Figure 1 and Fig.12After the position of the first pressing plate 51 is fixed, the pressing plate mold 50 continues to be pressed, and the second pressing plate 53 continues to move toward the pressing block mold 30, so that the extrusion head 531 contacts the second pressing block 35 and starts to squeeze the second pressing block 35. Under the action of pressure, the second pressing block 35 squeezes the sheet 200 to move toward the bottom wall 111 and the corner 115, so that the sheet 200 is squeezed and formed by the bottom mold 10 and the second pressing block 35. During the extrusion process, the second protrusion 351 squeezes the sheet 200, so that the thickness of the position of the bending portion 201 formed by the extrusion is lower than the thickness of other positions of the sheet 200, thereby avoiding the stress inside the sheet 200 from being concentrated at the position of the bending portion 201.
[0081] After the sheet 200 is extruded and formed by the first pressing block 33 and the second pressing block 35 in stages, the pressing plate module 50 starts to move away from the pressing block module 30. At this time, the second pressing block 35 first moves away from the sheet 200 under the action of the second spring 36. After the second pressing block 35 returns to the initial position, the first pressing block 33 starts to move away from the sheet 200 under the action of the first spring 34. After the first pressing block 33 and the second pressing block 35 return to the initial position, the pressing block module 30 is removed from the sheet 200, and the extruded sheet 200 can be taken out from the bottom die 10.
[0082] The plate extrusion molding device 100 provided in the embodiment of the present application is provided with a first protrusion 331 on the first pressing block 33 and a second protrusion 351 on the second pressing block 35, so that the thickness of the extruded plate 200 at the position of the bending portion 201 is compressed thin, thereby avoiding the plate 200 from being broken due to stress concentration during the bending process. By providing the first pressing block 33 to correspond to the groove wall 113 of the forming groove 11, the second pressing block 35 to correspond to the corner 115 of the forming groove 11, and the first pressing block 33 and the second pressing block 35 to extrude the plate 200 in stages, it is beneficial to position the plate 200 during the extrusion molding process and improve the molding accuracy. Specifically, by first applying pressure to the first pressing block 33 to extrude the plate 200, the position of the plate 200 can be fixed, and then applying pressure to the second pressing block 35 to extrude the plate 200, the second pressing block 35 can be filled into the gap between two adjacent first pressing blocks 33, so that the plate 200 is completely extruded.
