Because the width of the first connecting arm 2211 is smaller than that of the second connecting arm 2212, the first connecting arm 2211 and the second connecting arm 2212 form a T-shaped bump structure together, the first mounting groove 310 forms a T-shaped groove structure by arranging the first opening 3113, and the connection between the forming board 110 and the frame 120 is more stable due to the limitation of the T-shaped bumps and the T-shaped grooves, and the precision of the printed product is higher. Specifically, when the first connecting arm 2211 is clamped in the first opening 3113, the second connecting arm 2212 is clamped in the mounting groove, the side walls of the two opening ends of the first opening 3113 can limit the left and right of the first connecting arm 2211, so that the whole mounting arm 221 is not easy to slide left and right, the left and right position of the mounting arm 221 is kept with higher precision, the connection between the forming plate 110 and the rack 120 is stable, and therefore, when the forming plate 110 is used for taking materials relative to the material groove 130, the center position of each taking material is not easy to deviate, and the precision of a finally printed product is also higher.
Referring to fig. 1, 2 and 5, a second connection block 300 of the molding platform device according to an embodiment of the invention is provided with a second mounting groove 320 penetrating the first mounting groove 310, and the second mounting groove 320 is disposed at a side of the first mounting groove 310 away from the first connection assembly 200. The forming platform device further comprises a fixing assembly 400, the fixing assembly 400 is accommodated in the second installation groove 320, a buckle 411 is convexly arranged on one side, close to the first connecting assembly 200, of the fixing assembly 400, a clamping groove 2213 is formed in one side, close to the fixing assembly 400, of the second connecting arm 2212, and the buckle 411 can move close to or away from the clamping groove 2213. Specifically, the second mounting groove 320 is provided with a second opening 322 toward the sidewall of the first mounting groove 310, such that the second mounting groove 320 is penetrated with the first mounting groove 310 through the second opening 322. When the forming plate 110 needs to be mounted on the frame 120, at this time, the mounting arm 221 is clamped in the first mounting groove 310, the buckle 411 passes through the second opening 322 and moves close to the clamping groove 2213, the buckle 411 is matched with the clamping groove 2213 in a clamping manner, the second connecting arm 2212 is not easy to slide left and right relative to the first mounting groove 310, the position of the mounting arm 221 is kept to be higher in precision, when the forming plate 110 is taken relative to the material groove 130, the central position of each taking is not easy to deviate, and finally the precision of the printed product is also higher. When the forming plate 110 needs to be detached from the frame 120, the buckle 411 is moved away from the slot 2213, the buckle 411 is separated from the slot 2213, and the mounting arm 221 is separated from the first mounting slot 310.
Referring to fig. 4 and 5, a fixing assembly 400 of a molding platform device according to an embodiment of the invention includes a moving block 410 with a protruding buckle 411 and a first elastic member 420. The moving block 410 is slidably connected with the bottom wall of the second mounting groove 320, and the first elastic member 420 is abutted between the side wall of the second mounting groove 320 and the moving block 410; the first elastic member 420 serves to apply an urging force to the moving block 410 near the second connection arm 2212. Specifically, in the initial state, the first elastic member 420 is in a compressed state, so when the mounting arm 221 is clamped in the first mounting groove 310, the moving block 410 can slide along the bottom wall of the second mounting groove 320 toward one side of the second connecting arm 2212 under the pushing force of the first elastic member 420, and further the buckle 411 and the clamping groove 2213 achieve a clamping fit. In one embodiment, when the buckle 411 and the slot 2213 are in a clamping fit, the first elastic member 420 is still in a compressed state, so that the first elastic member 420 can continuously apply an urging force to the moving block 410, so that the clamping fit between the buckle 411 and the slot 2213 is stable. In one specific embodiment, the first elastic member 420 is a compression spring, and in other embodiments, the first elastic member 420 may be an elastic pad.
With continued reference to fig. 4 and 5, the moving block 410 of the forming table device according to an embodiment of the present invention is provided with an adjusting inclined plane 412, and the adjusting inclined plane 412 is disposed obliquely downward toward the second connecting arm 2212. The fixed assembly 400 further includes a pressing block 430, where the pressing block 430 can move along a vertical direction and is abutted against the adjusting inclined plane 412, so as to drive the moving block 410 to move away from the second connecting arm 2212. Specifically, the moving block 410 is provided with a third mounting groove 413, the adjusting inclined surface 412 is configured on a side wall of the third mounting groove 413, and the pressing block 430 extends into the third mounting groove 413 and abuts against the adjusting inclined surface 412. When the forming plate 110 needs to be detached from the frame 120, the user presses the pressing block 430 downwards, so that the pressing block 430 moves downwards along the direction in fig. 4, and then drives the adjusting inclined plane 412 to move leftwards, and the moving block 410 moves leftwards synchronously under the driving of the adjusting inclined plane 412, so that the buckle 411 is separated from the clamping groove 2213, and at the moment, the mounting arm 221 is separated from the first mounting groove 310, which is very simple and convenient.
When the forming plate 110 needs to be mounted on the frame 120 again, the user presses the pressing block 430 downwards first, so that the moving block 410 moves leftwards under the driving of the adjusting inclined plane 412, and the buckle 411 moves leftwards synchronously, so that the mounting arm 221 is not blocked by the buckle 411 when extending into the first mounting groove 310, and a very convenient card can be inserted into the first mounting groove 310. When the mounting arm 221 is snapped into the first mounting groove 310, the user stops pressing the pressing block 430, the moving block 410 stops receiving a horizontal leftward pushing force, and at this time, the first elastic member 420 in a compressed state applies a rightward pushing force to the moving block 410 near the second connecting arm 2212, so that the moving block 410 slides rightward along the bottom wall of the second mounting groove 320 toward one side of the second connecting arm 2212, and the pressing block 430 moves upward along the vertical direction, so that the clip 411 and the clip groove 2213 implement a clipping fit, and the mounting of the forming board 110 relative to the frame 120 is completed.
In one specific embodiment, a pressing surface 431 disposed obliquely downward toward the direction of the second connection arm 2212 is disposed on one side of the pressing block 430 close to the moving block 410, and the pressing surface 431 abuts against the adjusting inclined surface 412, so that the contact area between the pressing block 430 and the moving block 410 is increased. When the user presses the pressing block 430, the abutment force applied to the adjustment inclined surface 412 is more balanced, so that the moving block 410 can move more stably.
Referring to fig. 1, 2, 4 and 5, the fixing assembly 400 of the molding platform device according to an embodiment of the present invention further includes a mounting plate 440, where the mounting plate 440 is disposed at a side of the moving block 410 away from the bottom wall of the second mounting slot 320. The second mounting groove 320 has a protruding portion 321 on a side wall thereof facing the groove cavity, the mounting plate 440 is attached to the protruding portion 321, and the pressing block 430 passes through the mounting plate 440 and abuts against the adjustment inclined surface 412. Since the pressing block 430 passes through the mounting plate 440 to be in contact with the adjustment inclined surface 412, the pressing block 430 is not easy to slide left and right relative to the mounting plate 440, so that the position of the pressing block 430 is not greatly changed, and the contact between the pressing surface 431 and the adjustment inclined surface 412 is more stable. Meanwhile, as the mounting plate 440 is covered on the second mounting groove 320, sundries are not easy to fall into the second mounting groove 320 and influence the movement of the moving block 410, and the movement of the moving block 410 is stable. In one particular embodiment, the mounting plate 440 is adhesively coupled to the overlap 321 of the second mounting slot 320 such that the mounting plate 440 is more securely coupled to the overlap 321 of the second mounting slot 320.
Referring to fig. 2 and 3, a first slot wall 311 of a molding platform device according to an embodiment of the present invention includes a first ladder slot wall 3111 and a second ladder slot wall 3112 connected to the first ladder slot wall 3111; the first ladder groove wall 3111 is vertically oriented and the second ladder groove wall 3112 extends obliquely downward toward the first coupling assembly 200. The second connecting arm 2212 is adapted to the first groove wall 311, and the clamping groove 2213 is disposed on a side of the second connecting arm 2212 facing away from the first ladder groove wall 3111. Because the clamping groove 2213 is disposed on the side of the second connecting arm 2212 away from the first ladder groove wall 3111, when the buckle 411 is clamped in the clamping groove 2213, the first elastic member 420 continues to apply the pushing force to the moving block 410, the pushing force is transferred to the bottom wall of the clamping groove 2213 through the buckle 411 and transferred to the second connecting arm 2212 through the bottom wall of the clamping groove 2213, so that the second connecting arm 2212 is abutted with the first ladder groove wall 3111 more tightly.
It should be noted that, referring to fig. 3, since the first elastic member 420 applies a horizontal right pushing force to the moving block 410, the first ladder groove wall 3111 is vertical, so the horizontal right pushing force received by the first ladder groove wall 3111 is not required to be decomposed, and the size of the horizontal right pushing force received by the entire first ladder groove is the size of the pushing force of the first elastic member 420. If the first groove wall 311 extends downward obliquely toward the first connecting assembly 200, the second elastic member 500 applies the same pushing force to the first groove wall 311, and the pushing force is decomposed, the horizontal right pushing force applied to the entire first stepped groove wall 3111 is far smaller than the pushing force applied by the first elastic member 420. Because the horizontal thrust force to the right received by the first stepped groove in the present application is greater, the connection between the mounting arm 221 and the first mounting groove 310 is also more stable, the first connection assembly 200 is not easy to shake, and the positional accuracy of the forming plate 110 is higher. In this application, the size of the horizontal thrust to the right that the installation arm 221 receives is increased through first ladder cell wall 3111 to through the second ladder cell wall 3112 that the slope set up, make the installation arm 221 be difficult for breaking away from the top of first mounting groove 310, and then make the joint of installation arm 221 and first mounting groove 310 more firm.

One side of the mounting base 210 is connected with the molding plate 110, the other side of the mounting base 210 is connected with the first connection block 220, and the mounting arm 221 is configured on the first connection block 220. Because the mounting base 210 and the first connecting block 220 are separately designed, a profile is not required to be directly processed to meet the requirement of being connected with the forming plate 110 and arranging the mounting arm 221, and the processing cost of the whole forming platform device is low. In one particular embodiment, the side of the mounting block 210 facing away from the forming plate 110 is configured with a mounting cavity, and the side of the first connecting block 220 facing away from the mounting arm 221 is received in the mounting cavity and connected to the mounting block 210.

Since the plurality of elongated holes 211 are provided, when it is desired to level the forming plate 110, this can be accomplished by moving the link 230 within the elongated holes 211. In one specific embodiment, two elongated holes 211 are respectively disposed on two sidewalls of the mounting base 210 and spaced apart along the length direction of the mounting base 210, and four connecting members 230 respectively pass through one of the elongated holes 211 and are connected with the first connecting block 220. The number of the elongated holes 211 may be 6 or eight, and the number is not limited to this, and two or more may be provided on the side wall of each mounting seat 210, so that the forming plate 110 may be moved in the elongated holes 211 by the connecting member 230 to achieve its own horizontal adjustment function. In one specific embodiment, the connection block is a bolt, although in other embodiments, it may be a stud or screw, etc.

Specifically, when the mounting arm 221 is engaged with the first mounting groove 310, the second elastic member 500 is in a compressed state, the user presses the pressing block 430 downward to separate the buckle 411 from the engaging groove 2213, and the second elastic member 500 applies an upward pushing force to the mounting arm 221, which is separated from the first mounting groove 310, so that the upper surface of the mounting arm 221 protrudes from the upper surface of the first mounting groove 310, and the mounting arm 221 is more easily separated from the first mounting groove 310. In one embodiment, the mounting arm 221 is further provided with a fifth mounting groove 223 adjacent to the bottom wall of the first mounting groove 310 for accommodating the second elastic member 500, so that when the second elastic member 500 is released from the compressed state, elastic deformation can occur along the height direction of the fifth mounting groove 223, which is smoother and not easy to bend. In one specific embodiment, the second elastic member 500 is a compression spring, but in other embodiments, it may be an elastic pad.
