[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Please refer to Figures 1-10 , the embodiment of the present invention is: a high-precision mobile phone card holder production mold, including a die pressing platen 1, four vertical sliding columns 2 are arranged above the die pressing platen 1, the top ends of the vertical sliding columns 2 are fixedly connected with a top plate 3, a hydraulic cylinder 4 is installed on the top surface of the top plate 3, a die pressing mechanism 5 is arranged below the top plate 3, a filler mechanism 6 is arranged on the rear side of the die pressing mechanism 5, and a demolding mechanism 7 is arranged below the die pressing mechanism 5;

[0033] The die pressing mechanism 5 includes a slide block 51, the slide block 51 is slidably connected to the outside of each vertical sliding column 2, an upper pressing plate 52 is arranged below the top plate 3, a lower pressing plate 53 is arranged below the upper pressing plate 52, a plurality of injection hole needles 54 are fixedly connected to the bottom surface of the upper pressing plate 52, a plurality of equally spaced tooth grooves 58 are formed on the side surface of each vertical sliding column 2, four vibration plates 59 are fixedly connected to the bottom surface of the upper pressing plate 52, and the four vibration plates 59 are distributed in two groups on the bottom surfaces of the left and right sides of the upper pressing plate 52, a die pressing block 510 is fixedly connected to the bottom surface of the lower pressing plate 53, and a heating pipe 511 is electrically connected to the rear side of the socket 57.

[0034] The bottom surface of the die pressing platen 1 is provided with an embedded groove 9, and a shaping block 8 is fixedly connected inside the embedded groove 9. The upper surface of the die pressing platen 1 is provided with a material placing groove 11, and a material conveying hole 10 is arranged inside the material placing groove 11. The front side of the upper pressing plate 52 is fixedly connected with an insulating block 55, and an energized contact rod 56 is fixedly connected to the bottom surface of the insulating block 55. A socket 57 is arranged at the bottom surface of the energized contact rod 56. The four sliders 51 are divided into two groups and are respectively distributed on the left and right sides of the upper pressing plate 52 and the lower pressing plate 53. The slider 51 is slidably connected with the vertical sliding column 2. An outer spring is arranged at the bottom surface of the slider 51 connected to the side surface of the upper pressing plate 52, and both ends of the outer spring are fixedly connected to the slider 51 on the side surface of the upper pressing plate 52 and the slider 51 on the side surface of the lower pressing plate 53 respectively. A cross bar is arranged at the bottom surface of the slider 51 on the side surface of the lower pressing plate 53, and the cross bar is slidably connected with the vertical sliding column 2. The material conveying hole 10 penetrates from the inside of the material placing groove 11 to the inside of the embedded groove 9. An inner spring is arranged inside the vertical sliding column 2, and both ends of the inner spring are fixedly connected to the cross bar at the bottom surface of the slider 51 and the vertical sliding column 2 respectively. The injection hole needle 54 penetrates from the upper surface of the lower pressing plate 53 to the lower surface. The socket 57 is fixedly connected with the lower pressing plate 53. The upper pressing plate 52 in contact is pushed by the hydraulic cylinder 4, so that the upper pressing plate 52 slides down along the vertical sliding column 2 through the slider 51 connected to the side surface and compresses the outer spring. Since the outer spring has a large rigidity, at this time, the outer spring pushes the lower pressing plate 53 to slide down together with the upper pressing plate 52. Subsequently, the lower pressing plate 53 slides along the vertical sliding column 2 through the cross bar at the bottom surface of the side slider 51 and compresses the inner spring to be pressed, and approaches the top surface of the die pressing platen 1. As the hydraulic cylinder 4 continues to extend, the upper pressing plate 52 compresses the outer spring to deform and approaches the upper surface of the lower pressing plate 53. The insulating block 55 connected is driven by the upper pressing plate 52 to move downward, so that the insulating block 55 inserts into the socket 57 through the energized contact rod 56. Thus, the heating tube 511 is energized through the energized contact rod 56 by the circuit connected to the socket 57. The die pressing platen 1 in contact is heated by the heating tube 511 at the bottom surface of the lower pressing plate 53. The blank placed in the material placing groove 11 is melted by heating. With the continuous pushing of the hydraulic cylinder 4, the lower pressing plate 53 squeezes the material placing groove 11 through the pressing block 510 at the bottom surface, so that the melted material in the material placing groove 11 enters the periphery of the embedded groove 9 at the bottom surface of the die pressing platen 1 through the connected material conveying hole 10. At this time, the lower pressing plate 53 fits against the top surface of the die pressing platen 1 and stops moving. The continuously descending upper pressing plate 52 pushes the injection hole needle 54 to pass through the lower pressing plate 53 and enter the material conveying hole 10, so that the bottom surface of the injection hole needle 54 is flush with the top surface of the embedded groove 9. The material entering the embedded groove 9 changes its shape through the shaping block 8. When the material in the embedded groove 9 cools and forms, the power supply control is realized by moving the upper pressing plate 52 and the lower pressing plate 53 downward and approaching each other to control the energized contact rod 56 to connect the socket 57, which can avoid the heating tube 511 continuously working and consuming redundant energy. At the same time, by inserting the injection hole needle 54 into the material conveying hole 10, the melted batching can completely enter the embedded groove 9 from the material placing groove 11, avoiding the melted material remaining on the inner wall of the material conveying hole 10 and affecting the next material conveying and preventing blockage.This ensures that the molded tray in the embedded groove 9 is smooth and free of water holes, improving product quality. In addition, the vibration plate 59 moves downward with the lower pressure plate 53 to move the tooth groove 58 to generate vibration, causing bubbles contained in the melted material to float upward and be pressured out through the gap between the lower pressure plate 53 and the die plate 1, improving product quality and preventing bubbles from affecting the tray strength.

[0035] The stuffing mechanism 6 includes a pressing folding rod 61 which is slidably connected to the bottom surface of the top plate 3. The bottom end of the pressing folding rod 61 is slidably connected with a deflecting groove rod 63. The side surface of the deflecting groove rod 63 is rotatably connected with a fixed shaft rod 62. The bottom end of the deflecting groove rod 63 is slidably connected with a swing rod 66. Guide grooves 68 are fixedly connected to the left and right side surfaces of the pressing die table board 1. A material placing frame 65 is slidably connected inside the guide grooves 68. A blanking end shell 64 is fixedly connected to the rear top surface of the guide groove 68. A batching groove 611 is formed inside the blanking end shell 64. An elastic blocking frame 67 is slidably connected to the bottom surface of the blanking end shell 64. A pushing and blocking piece 69 is fixedly connected to the bottom surface of the elastic blocking frame 67. Reset elastic pieces 610 are fixedly connected to the left and right ends of the elastic blocking frame 67. The pressing folding rod 61 is slidably connected to the bottom end of the hydraulic cylinder 4, and there is damping when the pressing folding rod 61 contacts the hydraulic cylinder 4. The top end of the fixed shaft rod 62 is fixedly connected to the top plate 3. The swing rod 66 is fixedly connected to the material placing frame 65. A top spring is arranged between the pressing folding rod 61 and the top plate 3, and the two ends of the top spring are respectively fixedly connected to the pressing folding rod 61 and the top plate 3. The deflecting groove rod 63 is composed of a short rod and a long rod. The short rod is slidably connected to the pressing folding rod 61, and the long rod is slidably connected to the swing rod 66. A tension spring is arranged on the side surface of the reset elastic piece 610, and the two ends of the tension spring are respectively fixedly connected to the reset elastic piece 610 and the blanking end shell 64. The damping between the extending part of the hydraulic cylinder 4 and the pressing folding rod 61 drives the pressing folding rod 61 to slide downward and compress the top spring. When the pressing folding rod 61 moves downward to push the short rod of the deflecting groove rod 63 to deflect around the connection point of the fixed shaft rod 62 as a node, the long rod of the deflecting groove rod 63 swings and pushes the swing rod 66. The swing rod 66 drives the connected material placing frame 65 to slide along the guide groove 68. At this time, before the material placing frame 65 moves, it presses against the pushing and blocking piece 69, so that the pushing and blocking piece 69 drives the connected elastic blocking frame 67 to be pushed out from below the blanking end shell 64. The reset elastic pieces 610 connected to the elastic blocking frame 67 slide along the bottom surface of the blanking end shell 64 and make the tension spring in a tension state. At this time, the cut blank in the blanking end shell 64 falls into the material placing frame 65 and is flush with the top surface of the material placing frame 65. When the material placing frame 65 slides from the rear to the front along the guide groove 68, the three stacked blanks in the guide groove 68 slide along the surface of the pressing die table board 1 and are sequentially filled into the nearest material placing groove 11. After the material placing frame 65 moves forward, the reset elastic piece 610 drives the elastic blocking frame 67 to translate under the action of the tension spring to the bottom of the blanking end shell 64 to prevent the blank in the blanking groove 611 from continuing to fall. The damping makes the hydraulic cylinder 4 push the pressing folding rod 61 to move downward when extending, and drives the deflecting groove rod 63 to swing through the pressing folding rod 61, so that the deflecting groove rod 63 drives the material placing frame 65 to slide to automatically fill the blank above the pressing die table board 1, simplifying the steps of manual placement and improving the production efficiency of the card holder in a flow process. At the same time, the movement state of the material placing frame 65 is used to control the reset elastic piece 610 to drive the elastic blocking frame 67 to realize automatic feeding, automating the feeding step and realizing the integration of die production.

[0036] The demolding mechanism 7 includes two downward pressing folding rods 71, and the two downward pressing folding rods 71 are respectively fixedly connected to the left and right sides of the lower pressing plate 53. A rotating rod groove 72 is formed on the bottom surface of the die pressing table plate 1, and a deflecting folding rod 73 is rotatably connected to the inner wall of the rotating rod groove 72. A swinging groove column 74 is slidably connected to the side surface of the bottom end of the deflecting folding rod 73. A bottom pressing template 75 is arranged directly below the die pressing table plate 1, and a bottom plate 76 is arranged directly below the bottom pressing template 75. Guide groove blocks 77 are fixedly connected to the front and rear ends of the top surface of the bottom plate 76. Side sliding grooves 78 are formed on both the front and rear sides of the bottom pressing template 75. Short sliding columns 79 are fixedly connected to the four corners of the bottom surface of the die pressing table plate 1. Multiple die groove pushing blocks 710 are fixedly connected to the top surface of the bottom plate 76. A die groove plate 711 is fixedly connected to the top surface of the bottom pressing template 75. A die groove 712 is formed on the upper surface of the die groove plate 711. The bottom pressing template 75 is fixedly connected to the swinging groove column 74. The side sliding grooves 78 are slidably connected to the guide groove blocks 77. The short sliding columns 79 are slidably connected to the bottom pressing template 75. A spring piece is arranged between the bottom pressing template 75 and the bottom plate 76, and the two ends of the spring piece are respectively fixedly connected to the bottom pressing template 75 and the bottom plate 76. The die groove pushing blocks 710 slide upward from the bottom surface of the bottom pressing template 75 through to the top surface, and the die groove 712 is slidably connected to the die groove pushing blocks 710. The lower pressing plate 53 drives the connected downward pressing folding rods 71 to move, so that the downward pressing folding rods 71 push the deflecting folding rods 73 downward to deflect. After the deflecting folding rods 73 deflect, they drive the bottom pressing template 75 connected to the swinging groove column 74 to move upward, so that the bottom pressing template 75 slides along the short sliding columns 79 and approaches the bottom surface of the die pressing table plate 1. The short sliding columns 79 press against the top surface of the bottom plate 76 away from the bottom pressing template 75 and stretch the spring piece. Through the cooperation of the embedded groove 9 on the bottom surface of the die pressing table plate 1 and the die groove 712 on the top surface of the bottom pressing template 75, the material entering the die groove 712 is formed after cooling. When the lower pressing plate 53 resets upward, the downward pressing folding rods 71 no longer exert pressure on the deflecting folding rods 73. At this time, the bottom pressing template 75 resets along the short sliding columns 79 under the action of gravity. The bottom plate 76 is pulled and approaches the bottom pressing template 75 through the contraction of the spring piece, and the bottom pressing template 75 drives the die groove pushing blocks 710 to push the card holder in the die groove 712 upward, realizing automatic demolding. The die groove pushing blocks 710 completely push out the card holder in the die groove 712, avoiding the deformation and bending of the single-point force of the die groove 712 that is not completely cooled. At the same time, the residue in the die groove 712 is pushed upward and cleaned to avoid residue.

[0037] Working principle: When the hydraulic cylinder 4 extends downward, the hydraulic cylinder 4 pushes the contacted upper pressure plate 52, so that the upper pressure plate 52 slides downward along the vertical slide column 2 through the slider 51 connected to the side and squeezes the outer spring. Since the outer spring is relatively rigid, the outer spring pushes the lower pressure plate 53 downward together with the upper pressure plate 52. Then the lower pressure plate 53 slides along the vertical slide column 2 through the bottom cross bar of the side slider 51 to squeeze the inner spring under pressure and close to the top surface of the die plate 1. As the hydraulic cylinder 4 continues to extend, the upper pressure plate 52 squeezes the outer spring to deform and approach the upper surface of the lower pressure plate 53. The upper pressing plate 52 drives the connected insulating block 55 to move downward, so that the insulating block 55 is inserted into the socket 57 through the energized contact rod 56, so that the circuit connected to the socket 57 is energized through the energized contact rod 56 to energize the heating tube 511, and the heating tube 511 on the bottom of the lower pressing plate 53 heats the die platen 1 in contact with it, and the blank placed in the material trough 11 is melted by heating. The molten blank is continuously pushed by the hydraulic cylinder 4, so that the lower pressing plate 53 squeezes the material trough 11 through the pressing module 510 on the bottom, and the molten material in the material trough 11 is discharged through the connected The feeding hole 10 enters around the embedded groove 9 on the bottom surface of the die platen 1. At this time, the lower pressing plate 53 is in contact with the top surface of the die platen 1 and no longer moves. The upper pressing plate 52 that continues to move downward pushes the injection needle 54 through the lower pressing plate 53 and enters the feeding hole 10, so that the bottom surface of the injection needle 54 is flush with the top surface of the embedded groove 9. The material entering the embedded groove 9 is changed in shape by the shaping block 8. When the material in the embedded groove 9 is cooled and formed, the upper pressing plate 52 and the lower pressing plate 53 move downward and approach each other to control the power contact rod 56 to connect the socket 57 to realize power supply control, which can avoid the heating tube 511 from being continuously heated. The continuous work consumes excess energy. At the same time, the injection needle 54 is inserted into the feed hole 10 to allow the molten ingredients to completely enter the embedded groove 9 from the material trough 11, avoiding the molten material from remaining on the inner wall of the feed hole 10, affecting the next feeding and preventing blockage, ensuring that the molded card holder in the embedded groove 9 is flat and has no water outlet, thereby improving product quality. In addition, the vibration plate 59 moves downward with the lower pressure plate 53 to move the tooth groove 58 to generate vibration, so that the bubbles contained in the melting process float upward and are pressured and discharged from the gap between the lower pressure plate 53 and the die plate 1, thereby improving product quality and avoiding bubbles affecting the strength of the card holder.

[0038] When the hydraulic cylinder 4 extends downward and has not yet contacted the top surface of the upper pressure plate 52, the damping existing between the extending part of the hydraulic cylinder 4 and the pressure-applying folding rod 61 drives the pressure-applying folding rod 61 to slide downward and compress the top spring. When the pressure-applying folding rod 61 moves downward and pushes the short rod of the deflection groove rod 63 to deflect with the connection point of the fixed shaft rod 62 as the node, the long rod of the deflection groove rod 63 swings and pushes the swing rod 66. The swing rod 66 drives the connected blanking frame 65 to slide along the guide groove 68. At this time, before the blanking frame 65 moves forward, it presses against the push-block 69, causing the push-block 69 to drive the connected elastic blocking frame 67 to be pushed out from under the blanking end shell 64. The reset elastic sheet 610 connected to the elastic blocking frame 67 slides along the bottom surface of the blanking end shell 64 and keeps the tension spring in a tension state. At this time, the cut blank in the blanking end shell 64 falls into the blanking frame 65 and is flush with the top surface of the blanking frame 65. When the blanking frame 65 slides from the back to the front along the guide groove 68, the three stacked blanks in the guide groove 68 slide along the surface of the die pressing platen 1 and are sequentially filled into the nearest material placement groove 11. After the blanking frame 65 moves forward, the reset elastic sheet 610 drives the elastic blocking frame 67 to translate under the action of the tension spring to block the blank in the blanking groove 611 from continuing to fall. The damping causes the hydraulic cylinder 4 to push the pressure-applying folding rod 61 downward when extending, and the pressure-applying folding rod 61 drives the deflection groove rod 63 to swing, causing the deflection groove rod 63 to drive the blanking frame 65 to slide to automatically fill the blank above the die pressing platen 1, simplifying the steps of manual placement and improving the production efficiency of the caddy in a flowing water manner. At the same time, the movement state of the blanking frame 65 is used to control the reset elastic sheet 610 to drive the elastic blocking frame 67 to achieve automatic blank feeding, automating the feeding step and realizing the integration of die production;

[0039] When the lower pressure plate 53 moves downward, the lower pressure plate 53 drives the connected lower pressure folding rod 71 to move, causing the lower pressure folding rod 71 to push the deflection folding rod 73 downward to deflect. After the deflection folding rod 73 deflects, it drives the bottom pressure template 75 connected to the swing groove column 74 to move upward, causing the bottom pressure template 75 to slide along the short sliding column 79 and approach the bottom surface of the die pressing platen 1. The short sliding column 79 abuts against the top surface of the bottom plate 76 away from the bottom pressure template 75 and stretches the spring piece. Through the cooperation of the embedded groove 9 on the bottom surface of the die pressing platen 1 and the die groove 712 on the top surface of the bottom pressure template 75, the material entering the die groove 712 is formed after cooling. When the lower pressure plate 53 resets upward, the lower pressure folding rod 71 no longer exerts pressure on the deflection folding rod 73. At this time, the bottom pressure template 75 resets along the short sliding column 79 under the action of gravity. The bottom plate 76 is pulled and approaches the bottom pressure template 75 through the contraction of the spring piece, and the bottom pressure template 75 drives the die groove push block 710 to push the caddy in the die groove 712 upward to achieve automatic demoulding. The die groove push block 710 completely pushes out the caddy in the die groove 712, avoiding the single-point force deformation and bending of the die groove 712 that is not fully cooled, and at the same time pushing up and cleaning the residue in the die groove 712 to avoid residue.
