Description

Technical Field

[0001] The present application relates to the field of automobile parts processing, and in particular to a mold for molding decorative panels. Background Art

[0002] Car trim panels can decorate the interior of a car and are commonly used in car doors, roofs, and central consoles. They can not only beautify the interior space of the car, but also provide some protection for the car body.

[0003] like Figure 1 The figure shows a schematic diagram of the structure of an existing automotive trim panel 100. One side of the trim panel 100 is provided with a plurality of raised portions 110 with circular end faces, and the circular end faces of the raised portions 110 are provided with through holes 120. The side of the raised portions 110 and the trim panel 100 are transitioned through a transition edge 130. The existing molding process of the trim panel 100 basically includes the following steps: 1. The blank plate is bent and extruded by a moving core to form the required raised portions 110; 2. The through holes 120 are punched out of the end faces of the raised portions 110; 3. The edges of the blank plate are trimmed to obtain the required trim panel. As can be seen from the above molding process, the processing of the existing trim panel 100 is currently divided into multiple steps, and an independent driving source is required between each step to work, which will lead to an increase in the molding cost of the trim panel 100 and increase the difficulty of mold design.

[0004] At the same time, if Figure 2 FIG. 1 is a partially enlarged schematic diagram of the transition edge 130.

Therefore, bending a large area of ​​SMC sheet simultaneously over a large bending span may cause cracking in the transition edge 130, thereby increasing the scrap rate of the sample.

DETAILED DESCRIPTION

[0036] Hereinafter, the present application will be further described in conjunction with specific embodiments. It should be noted that, under the premise of not conflicting, the embodiments described below or the technical features between them can be combined to form new embodiments.

[0037] In the description of the present application, it should be noted that, for orientation words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. The orientation and positional relationship shown in the drawing is based on the orientation or positional relationship, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0038] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0039] One of the preferred embodiments of the present application is shown in Figure 3 and Figure 4 A plaque die forming die, comprising a movable die plate 210 and a fixed die plate 220, and a first forming die group 4, a second forming die group 6 and a plurality of punching assemblies 5 movably installed on the fixed die plate 220. The punching assembly 5 can be cooperated with the first forming die group 4 and the second forming die group 6 respectively through the traction structure.

[0040] When the die forming of the decorative plate 100 is performed, first, the blank 700 to be die formed can be placed on the movable die plate 210, and positioned and matched with the positioning pins on the movable die plate 210 through the positioning holes previously formed on the blank 700, so as to ensure that the blank 700 can be kept stable during the movement of the movable die plate 210. Then, the movable die plate 210 can drive the placed blank 700 to move from the position away from the first forming die set 4, the second forming die set 6 and the punching assembly 5 to the direction close to the fixed die plate 200, until the required decorative plate 100 can be finally obtained through the extrusion of the blank 700 with the first forming die set 4 and the second forming die set 6 respectively, and the punching of the punching assembly 5.

[0041] Wherein, the specific process of the blank 700 approaching the fixed die plate 220 under the driving of the movable die plate 210 to continue the die forming includes the first process and the second process performed in sequence. Wherein, the first process: the movable die plate 210 drives the blank 700 to be extruded with the first forming die set 4 to form the non-transition edge area of the protruding part 110; during this process, the punching assembly 5 and the second forming die set 6 remain stationary and are spaced apart from the blank 700. The second process: after the die forming of the blank 700 is completed, the first forming die set 4 can keep the blank 700 in the pressed state to move synchronously with the movable die plate 210; during the movement of the first forming die set 4, the punching assembly 5 can be driven by the traction structure to punch the end face of the protruding part 110; at the same time, the second forming die set 6 can also be driven by the traction structure to stepwise extrude the side part of the blank 700 to form the transition edge 130.

[0042] It can be understood that, compared with the traditional multi-drive source step-by-step driving, the traction structure is used in the present application to link the first forming die set 4, the second forming die set 6 and the punching assembly 5 respectively. And during the whole die forming process, the step-by-step movement between the first forming die set 4, the second forming die set 6 and the punching assembly 5 is powered by the extrusion of the movable die plate 210, so as to avoid the use of multiple drive sources, thereby reducing the design difficulty and effectively reducing the die forming cost. Moreover, the forming of the transition edge 130 can be step-by-step demoulded by the second forming die set 6, which can ensure that the corresponding position of the blank 700 has enough stress release space during the forming of the transition edge 130, so as to reduce or avoid the cracking of the blank 700 during the forming of the transition edge 130, thereby effectively improving the forming quality and the qualification rate of the decorative plate 100.

[0043] It can also be understood that the number of the punching assembly 5 can be determined according to the number of the through hole 120 on the decorative plate 100 to be die formed. For example Figure 1 As shown, the number of the through hole 120 is four, and the number of the punching assembly 5 corresponds to four.

[0044] In the present embodiment, asFigure 3 and Figure 4 As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained.

[0045] As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained. Figure 5 Figures 10 to 13 As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained.

[0046] As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained. Figures 10 to 11 As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained.

[0047] Figure 12 As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained. Figure 13 As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained.

[0048] As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained.

[0049] Figure 5 As shown in FIG. 1 and FIG. 2, the cutting module 300 is installed on the side of the first forming module 4 and the second forming module 6 of the fixed die plate 220, and the cutting module 300 can be vertically driven by a separate driving source (not shown). Thus, after the blank 700 is completed by the second process to form the corresponding protruding portion 110 and the through hole 120, the cutting module 300 can cut off the excess edge of the blank 700 along the side of the first forming module 4 and the second forming module 6 under the driving of the corresponding driving source, and thus the complete decorative plate 100 can be obtained. Figures 10 to 13 ​​​As shown, the lower end of the first movable module 42 is used for forming the non-transition edge area of the protruding part 110, and the upper end of the first movable module 42 is provided with a plurality of third guide rods 421; a plurality of first sliding holes 410 are correspondingly provided on the fixed module 41, and the first movable module 42 can be slidably connected with the corresponding first sliding hole 410 through the third guide rod 421. The third guide rod 421 is sleeved with a first spring 43, and the two ends of the first spring 43 are connected with the fixed module 41 and the first movable module 42 respectively; so as to realize the elastic sliding connection between the first movable module 42 and the fixed module 41; and the cooperation of the plurality of third guide rods 421 and the corresponding first sliding holes 410 can improve the sliding accuracy and stability of the first movable module 421.

[0050] It can be understood that the specific number of the third guide rod 421 and the corresponding first sliding hole 410 can be determined according to actual needs; for example Figure 5 As shown, the number of the third guide rod 421 and the corresponding first sliding hole 410 is four. At the same time, the first spring 43 can preferably adopt a rectangular spring, which has a larger elastic coefficient, so as to generate a larger elastic force through a smaller moving distance of the first movable module 42 to realize the extrusion forming of the blank 700.

[0051] One of the embodiments of the present application, as shown in Figure 7 , Figures 10 to 13 As shown, the punching assembly 5 includes a punching rod 51, which is elastically and slidably installed in the first movable module 42, and one end of the punching rod 51 is provided with a punching head 511 for punching the blank 700 to form a through hole 130.

[0052] When the first process is performed, as shown in Figure 10 and Figure 11 , the punching head 511 of the punching rod 51 is located in the first movable module 42 for relative sliding to ensure that the punching head 511 does not contact the blank 700.

[0053] When the second process is performed, as shown in Figure 12 and Figure 13 , the punching rod 51 is driven by the traction structure to extend out of the first movable module 42, so as to punch the through hole 120 on the end face of the protruding part 110 formed in the first process.

[0054] It can be understood that the punching rod 51 can be slidably installed in the first movable module 42, or slidably installed in the fixed module 41, or slidably installed in the fixed module 220. In order to facilitate the subsequent setting of the traction structure, the punching rod 51 is preferably slidably installed in the guide hole 422 provided on the first movable module 42 in the embodiment.

[0055] Meanwhile, the punching rod 51 can be elastically slidably connected through the second spring 52, and the purpose of the elastic connection of the punching rod 51 through the second spring 52 is to complete the demolding after the forming of the decorative plate 100, and the punching rod 51 can be automatically demolded and reset through the elastic force of the second spring 52. There are many installation methods of the second spring 52, including but not limited to the following three kinds. The first kind: the second spring 52 is sleeved on the punching rod 51, one end of the second spring 52 abuts against the punching rod 51, and the other end abuts against the first movable die module 42. The second kind: one end of the second spring 52 is connected to the punching rod 51, and the other end is connected to the fixed die module 41; the third kind: one end of the second spring 52 is connected to the punching rod 51, and the other end is connected to the fixed die module 220. Similarly, in order to avoid interference with the subsequent traction structure, the installation of the second spring 52 in the embodiment preferably adopts the first installation method described above.

[0056] In the embodiment, as shown in Figures 10 to 13 , the movable die plate 210 is provided with a plurality of avoidance holes 211 corresponding to the number and position of the punching rods 51; and after the punching head 511 completes the punching on the blank 700, it can extend into the avoidance hole 211, thereby ensuring the smooth punching of the through hole 120, and also avoiding the interference between the punching head 511 and the movable die plate 210.

[0057] In one of the embodiments of the application, as shown in Figures 8 to 13 and Figures 15 to 17 , the second forming die set 6 includes a second movable die module 61 and a plurality of third movable die modules 62. The second movable die module 61 and the third movable die module 62 are both elastically slidably connected with the fixed die plate 220; the second movable die module 61 and the third movable die module 62 can both be connected with the punching assembly 5 through the traction structure.

[0058] When the first process is performed, as shown in Figure 10 , Figure 11 and Figure 15 , the forming ends of the second movable die module 61 and the third movable die module 62 are aligned and spaced apart from the forming end of the first forming die set 4 in the die pressing direction, so as to ensure that the second forming die set 6 does not contact the blank 700 during the die pressing process of the first forming die set 4 on the non-transition edge of the protruding part 110 of the blank 700.

[0059] When the second process is performed, as shown in Figure 16 and Figure 17As shown, the traction structure can first drive the third movable mold 62 to slide a set distance towards the blank 700; then the traction structure can keep the third movable mold 62 stationary and continue to drive the second movable mold 61 to slide towards the blank 700 until it is flush with the third movable mold 62. During this process, the movable mold 210 always moves the placed blank 700 towards the stationary mold 220, and then the third movable mold 62 and the second movable mold 61 are in contact with the blank 700 in turn to extrude and form the transition edge 130 in steps.

[0060] It can be understood that the traction structure can also first drive the second movable mold 61 to slide towards the blank 700, and then keep the second movable mold 61 stationary to continue to drive the third movable mold 62 to slide towards the blank 700. For the convenience of subsequent description, the embodiment is described by taking the example that the traction structure first drives the third movable mold 62 to move towards the blank 700, and then keeps the third movable mold 62 stationary to continue to drive the second movable mold 61 to slide towards the blank 700.

[0061] It can also be understood that the number of third movable molds 62 can correspond to the number and position of the punching assemblies 5, that is, the number of third movable molds 62 is four, and they are respectively located on the side of the corresponding punching assembly 5. In order to further ensure the stability of the relative sliding between the second movable mold 61 and the third movable mold 62, the third movable mold 62 and the second movable mold 61 can be slidably connected through a clamping groove structure.

[0062] In the embodiment, as shown in the figure, Figures 8 to 13 The second movable mold 61 is provided with a second sliding hole 610, and the third movable mold 62 is provided with a third sliding hole 620; the stationary mold plate 220 is fixed with a first guide rod 221 and a second guide rod 222. The stationary mold plate 220 is slidably connected with the second sliding hole 610 through the first guide rod 221; a third spring 63 is sleeved on the first guide rod 221, and the two ends of the third spring 63 are respectively connected with the stationary mold plate 220 and the second movable mold 61, so as to realize the elastic sliding connection between the second movable mold 61 and the stationary mold plate 220. The stationary mold plate 220 is slidably connected with the third sliding hole 620 through the second guide rod 222; a fourth spring 64 is sleeved on the second guide rod 222, and the two ends of the fourth spring 64 are respectively connected with the stationary mold plate 220 and the third movable mold 62, so as to realize the elastic sliding connection between the third movable mold 62 and the stationary mold plate 220. The purpose of the elastic connection between the second movable mold 61 and the third movable mold 62 is that when the decorative plate 100 is formed and demolded, the second movable mold 61 and the third movable mold 62 can be reset by the elastic force of the corresponding spring.

[0063] It can be understood that, due to the large structural size of the second moving module 61, the number of the second sliding holes 610 can be set to be multiple, and the fixed mold plate 220 is slidably matched with the multiple corresponding first guide rods 221; the specific number of the first guide rods 221 and the second sliding holes 610 can be selected according to actual needs, for example Figure 8 As shown in the figure, the specific number of the first guide rods 221 and the second sliding holes 610 is four. The number of the second guide rods 222 corresponding to the third moving module 62 is four.

[0064] In one of the embodiments of the present application, as Figures 5 to 7 and Figures 10 to 13 shown, the traction structure includes a traction sleeve 44 and a driving plate 531. The driving plate 531 is rotationally installed through the middle part, and the first end of the driving plate 531 is hingedly connected with the punching rod 51 through a hinge plate 532. The traction sleeve 44 is rotationally arranged, the outer side of the traction sleeve 44 is matched with the second forming module 6, and the punching rod 51 penetrates the middle line of the traction sleeve 44 and is matched.

[0065] Initially, as Figure 10 shown, the second end of the driving plate 531 is located in the first sliding hole 410, and there is a certain spacing between the second end of the driving plate 531 and the third guide rod 421.

[0066] When the first process is performed, as Figure 11 shown, as the first moving module 42 slides under the extrusion of the moving mold plate 210, the spacing distance between the third guide rod 421 on the first moving module 42 and the second end of the driving plate 531 gradually decreases until they contact each other.

[0067] When the second process is performed, as Figure 12 and Figure 13 shown, as the first moving module 42 continues to move, the second end of the driving plate 531 is rotationally driven by the third guide rod 421 around the installation position, and then drives the punching rod 51 to slide towards the blank 700 to extend out of the first moving module 42 through the hinge plate 532. And in the process of sliding the punching rod 51, the traction sleeve 44 can be driven to rotate, and then the third moving module 62 and the second moving module 61 are sequentially driven to slide towards the blank 700 through the rotation of the traction sleeve 44, until the second moving module 61 and the third moving module 62 step by step extrude and form the side part of the blank 700 into the corresponding transition edge 130.

[0068] In the embodiment, as Figures 10 to 13As shown in the drawings, the first sliding hole 410 is provided with an avoiding groove 411 near the end side of the fixed mold plate 220. The driving plate 531 can be rotatably installed with the fixed mold module 41 through the middle part; or, the driving plate 531 can be rotatably installed with the fixed mold plate 220; in order to facilitate the description of the subsequent content, the embodiment takes the driving plate 531 rotatably installed with the fixed mold module 41 through the middle part as an example. Thus, the second end of the driving plate 531 can extend into the first sliding hole 410 along the avoiding groove 411, and then in the second process, the extrusion of the third guide rod 421 to the driving plate 531 can drive it to rotate around the installation position.

[0069] In the embodiment, as shown in Figure 6 、 Figure 7 and Figure 14 , the inner side of the traction sleeve 44 is provided with a first traction block 441; the outer side of the punching rod 51 is provided with a spiral traction groove 512 in the axial direction. The traction groove 512 can be slidably matched with the first traction block 441; thus, in the second process, when the punching rod 51 moves axially, the relative sliding of the first traction block 441 along the traction groove 512 can drive the traction sleeve 44 to rotate circumferentially; that is, the punching rod 51 drives the traction sleeve 44 to rotate circumferentially by axial movement.

[0070] It can be understood that the traction groove 512 can also be arranged on the inner wall of the traction sleeve 44, and the first traction block 441 can be arranged on the outer side of the punching rod 51; both ways can meet the use requirements, and those skilled in the art can choose according to actual needs; in order to facilitate the description of the subsequent content, the subsequent content takes the traction groove 512 arranged on the outer side of the punching rod 51 and the first traction block 441 arranged on the inner side of the traction sleeve 44 as an example for description.

[0071] In the embodiment, as shown in Figure 8 、 Figure 9 、 Figures 15 to 17 , the second movable mold module 61 is provided with an arc-shaped first placement groove 611, and the third movable mold module 62 is provided with an arc-shaped second placement groove 621. The number of the first placement grooves 611 corresponds to the number of the third movable mold modules 62, and then the first placement grooves 611 and the second placement grooves 621 on the corresponding third movable mold modules 62 can be aligned with each other to form a placement cavity 600. The traction sleeve 44 is located in the placement cavity 600 and cooperates with the first placement grooves 611 and the second placement grooves 621 respectively, and then in the process of rotating the traction sleeve 44, the third movable mold modules 62 and the second movable mold modules 61 can be driven to move in sequence.

[0072] In the embodiment, as shown in Figure 5 、 Figures 9 to 13As shown, the side of the placement cavity 600 is provided with an opening; the rotating seat 412 arranged on the fixed mold 41 or the fixed mold plate 220 can extend into the placement cavity 600 through the opening, and then the traction sleeve 44 is rotatably arranged on the rotating seat 412 in the placement cavity 600; so as to ensure that the traction sleeve 44 can stably rotate in the placement cavity 600.

[0073] In this embodiment, as shown in Figure 6 、 Figure 9 、 Figures 15 to 17 As shown, the side wall of the first placement groove 611 is provided with a second traction block 612, and the side wall of the second placement groove 621 is provided with a third traction block 622. The outer side of the traction sleeve 44 is provided with a traction rail, which includes an inclined first traction section 442 and a circumferentially extending second traction section 443.

[0074] When the traction sleeve 44 rotates under the driving of the punching rod 51, as shown in Figure 15 and Figure 16 , the traction sleeve 44 can drive the traction rail to first pass through the first traction section 442 and the third traction block 622 for extrusion, thereby driving the third movable mold 62 to move towards the blank 700. As the traction sleeve 44 rotates, when the first traction section 442 extrudes the second traction block 612, as shown in Figure 17 , the third traction block 622 can cooperate with the second traction section 443 to keep the third movable mold 62 stationary.

[0075] It can be understood that in the rotating direction of the traction sleeve 44, the first traction section 442 first extrudes and cooperates with the third traction block 622, and then cooperates with the second traction block 612. The arc length distance between the third traction block 622 and the second traction block 612 in the axial projection point of the placement cavity 600 is greater than the projection length of the first traction section 442; so as to ensure that when the first traction section 442 cooperates with the second traction block 612, the second traction section 443 can abut against the third traction block 622, thereby keeping the third movable mold 62 stationary under the elastic pulling of the fourth spring 64.

[0076] For the convenience of understanding, the entire process of molding the blank 700 to form the decorative plate 100 will be described in detail below.

[0077] I. Initially, as shown in Figure 10 , there is a gap between the forming end of the first movable mold 42 and the movable mold plate 210, and the forming end of the first movable mold 42 is closer to the movable mold plate 210 than the forming ends of the second movable mold 61 and the third movable mold 62.

[0078] At this time, the punching head 511 of the punching rod 51 is located in the guide hole 422 of the first moving module 42. There is a gap between the second end of the driving plate 531 and the third guide rod 421.

[0079] At this time, the blank 700 can be placed on the movable platen 210 and positioned and matched.

[0080] 2. When the first process is carried out, Figures 10 to 11 As shown, the movable template 210 drives the blank 700 to approach and extrude toward the first movable module 42; when the first movable module 42 is under pressure, the first movable module 42 can compress the first spring 43, and then as the elastic deformation of the first spring 43 increases, sufficient extrusion force is provided to the blank 700 to form the non-transition edge area of ​​the protrusion 110.

[0081] During this process, the first movable module 42 can also squeeze the second spring 52. Since the elastic force generated by the second spring 52 is small, the punching rod 51 can remain stationary or slide slightly toward the fixed template 220 to drive the hinged plate 532 to drive the second end of the driving plate 531 toward the third guide rod 421.

[0082] During this process, as the first moving module 42 moves, the third guide rod 421 can slide along the first sliding hole 410 toward the driving plate 531 until it contacts the second end of the driving plate 531 .

[0083] During this process, the forming ends of the second moving module 61 and the third moving module 62 are still spaced apart from the forming end of the first moving module 42 .

[0084] 3. When the second process is performed, it includes the first action and the second action.

[0085] First action: Figure 12 As shown, the first movable module 42 slides synchronously in the direction of compressing the first spring 43 by contacting the movable template 210 and following the movable template 210, and then the second end of the driving plate 531 can be squeezed by the third guide rod 421 to drive it to rotate around the middle installation position, so that the driving plate 531 drives the hinge plate 532 through the first end to drive the punching rod 51 to extend out of the first movable module 42 along the guide hole 422 and compress the second spring 52, thereby punching the end face of the formed protrusion 110 to form a through hole 120.

[0086] In this process, if Figure 14 As shown in (1) and (2), during the axial movement of the punching rod 51, the traction sleeve 44 can be driven to rotate by sliding the traction groove 512 relative to the first traction block 441.

[0087] During the rotation of the traction sleeve 44, as shown in Figure 15 and Figure 16 illustrated, the traction sleeve 44 can drive the third movable mold module 62 to slide towards the blank 700 and stretch the fourth spring 64 by the extrusion of the first traction section 442 and the third traction block 622, until the first traction section 442 is close to the second traction block 612, and the second traction section 443 is in abutting cooperation with the third traction block 622. During this process, the second movable mold module 61 always remains stationary under the elastic force of the third spring 63.

[0088] When the first action is completed, the forming ends of the second movable mold module 61 and the third movable mold module 62 are both spaced from the forming end of the first movable mold module 42, and the spacing distance between the forming end of the third movable mold module 62 and the forming end of the first movable mold module 42 is smaller than the spacing distance between the forming end of the second movable mold module 61 and the forming end of the first movable mold module 42.

[0089] Second action: as shown in Figure 13 , the first movable mold module 42 continues to slide in the direction of compressing the first spring 43 by abutting contact with the movable mold plate 210, so that the punching rod 51 can continue to slide in the direction of extending out of the first movable mold module 42 and compress the second spring 52.

[0090] During this process, as shown in Figure 14 (2), during the axial movement of the punching rod 51, the traction sleeve 44 can continue to rotate by the sliding of the traction groove 512 relative to the first traction block 441.

[0091] During the continuous rotation of the traction sleeve 44, as shown in Figure 16 , the traction sleeve 44 can cooperate with the third traction block 622 through the second traction section 443 to keep the third movable mold module 62 relatively stationary. At the same time, the traction sleeve 44 can drive the second movable mold module 61 to slide towards the blank 700 and stretch the third spring 63 by the extrusion of the first traction section 442 and the second traction block 612, until the forming ends of the second movable mold module 61 and the third movable mold module 62 are flush with the forming end of the first movable mold module 42, as shown in Figure 13 . During this process, the movable mold plate 210 can first extrude the forming end of the second movable mold module 61 and then the forming end of the third movable mold module 62 to realize step-by-step forming of the transition edge 130.

[0092] When the demolding of the decorative plate 100 is performed, the movable mold 210 drives the formed decorative plate 100 to move away from the fixed mold plate 220; in this process, the first movable mold 42 is reset under the elastic force of the first spring 43, and the punching rod 51 is reset under the elastic force of the second spring 52, so as to drive the traction sleeve 44 to reset; in the resetting process of the traction sleeve 44, the second movable mold 61 and the third movable mold 62 are reset under the elastic force of the third spring 63 and the fourth spring 64 respectively.
