Description

Technical Field

[0001] The utility model relates to the technical field of a manipulator for injection molds, in particular to a mold-taking manipulator for plastic injection molds. Background Art

[0002] Injection molding robots are specially designed for use in injection molding production lines. After injection molding, the robot can quickly enter the mold and take out the molded product or waste, reducing the residence time of the finished product in the mold and avoiding product deformation or damage. The taken out products can be accurately placed in the designated position by the robot and even classified according to product type or quality.

[0003] In the prior art, a suction cup is provided on the injection molding robot to fix the bottom of the product and then transfer the product. For products with deeper depth, the contact area between the side wall of the product and the mold increases, resulting in increased friction between the mold and the product. This increased friction requires greater force to remove the product from the mold, thereby increasing the difficulty of operation. Secondly, due to the large friction, when the suction cup tries to adsorb the bottom of the product and pull it out of the mold, there is a risk of the suction cup detaching from the product, which not only affects the production efficiency of the plastic product, but also may cause interruption of the production process. In addition, the product may wear or even break during the pulling process. This damage not only affects the appearance quality of the product, but also may cause the product to fail to meet the use requirements, thereby affecting the overall product qualification rate.

[0004] Therefore, it is necessary to design a mold-taking robot for plastic injection molds to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A mold removal robot for a plastic injection mold includes a robot 1. The specific internal structure and working principle of the robot 1 are all existing technologies and are not the innovative part of the utility model. No further details will be given here. A fixing plate 2 is provided at the clamping end of the robot 1. The fixing plate 2 is hollow. A plurality of suction cups 3 are provided on the lower surface of the fixing plate 2. A fan 4 is provided on the robot 1. An air inlet pipe 5 is provided at the air inlet end of the fan 4. The air inlet pipe 5 is connected to the suction cup 3. Four reinforcing components are provided inside the fixing plate 2. The reinforcing components are used to strengthen the connectivity between the device and the product. A vibration component is provided inside the fixing plate 2.

[0024] Reference Figure 2 The reinforcement component includes a plurality of suction cups 6 arranged on the side wall of the fixed plate 2, the suction cups 6 are connected with a connecting pipe 7, the connecting pipe 7 is connected with the air intake pipe 5, and a connecting piece is provided on the fixed plate 2, the connecting piece is used to connect the suction cups 6 and the fixed plate 2.

[0025] Reference Figure 3 and Figure 5The connecting member includes a moving cavity 13 arranged inside the fixed plate 2, a slide plate 12 is slidably connected inside the moving cavity 13, a plurality of springs 11 are arranged between the slide plate 12 and the moving cavity 13, a sliding rod 10 matching the number of suction cups 6 is fixedly connected to the side wall of the sliding rod 12, one end of the sliding rod 10 away from the sliding rod 12 extends to the outside of the fixed plate 2, and the sliding rod 10 is slidably connected to the fixed plate 2, one end of the sliding rod 10 located outside the fixed plate 2 is fixedly connected to a mounting block 8, a placement groove 9 is arranged on the side wall of the mounting block 8, and the suction cup 6 is fixedly connected to the inner side of the placement groove 9. By arranging the suction cup 6, the suction cup 6 can generate an adsorption force on the side wall of the product during the demoulding process, so that the force applied by the device to the product can be dispersed, thereby ensuring the firmness of the device fixing the product and preventing the product from being damaged due to uneven force. Especially for products with a deeper depth, the force applied by the suction cup 6 to the side wall of the product can improve the efficiency of demoulding.

[0026] Reference Figure 2 , Figure 3 and Figure 4 The vibration assembly includes a rotating shaft 15 rotatably connected to the inner bottom surface of the fixed plate 2, a wire roller 16 is fixedly sleeved on the rotating shaft 15, a pull rope 14 is fixedly connected to the side walls of the four slide plates 12, the pull rope 14 is fixedly connected to the wire roller 16, a complete gear 17 is also fixedly sleeved on the rotating shaft 15, a motor 19 is fixedly connected to the fixed plate 2, an incomplete gear 18 is fixedly sleeved on the output shaft of the motor 19, the incomplete gear 18 is meshed with the complete gear 17, under the intermittent meshing of the complete gear 17 and the incomplete gear 18, the pull rope 14 can intermittently pull the mounting block 8 and the suction cup 2 6, so that the side wall of the product intermittently undergoes slight deformation, so that during the demoulding process, the side wall of the product can vibrate, and then there is a gap between the side wall and the mold, making the demoulding faster and smoother.

[0027] Reference Figure 3 and Figure 5 The side wall of the mounting block 8 is provided with an inclined surface, so that when the fixing plate 2 moves into the interior of the product, the side wall of the product will squeeze the mounting block 8 under the action of the inclined surface, so that the mounting block 8 is completely located inside the product, and the suction cup 2 6 can be against the inner side of the product to ensure the stability of the fixation.

[0028] Reference Figure 3 The length of the slide plate 12 matches the length of the moving cavity 13, and the inner side of the moving cavity 13 guides the slide plate 12, so that the moving states of the suction cups 6 on the same slide plate 12 are the same, ensuring uniform force on the product.

[0029] The specific working principle of the utility model is as follows:

[0030] When removing the mold, the staff controls the manipulator 1 so that the fixed plate 2 is located inside the product and the suction cup 3 can contact the inner bottom of the product. In the process of the fixed plate 2 moving into the interior of the product, the side wall of the product will squeeze the mounting block 8. Under the action of the inclined surface of the side wall of the mounting block 8, the mounting block 8 and the slide bar 10 will move toward the fixed plate 2. When the fixed plate 2 moves to the appropriate position, under the action of the spring 11, the suction cup 2 6 will always be in contact with the inner side of the product. Then the fan 4 is started, and the air between the suction cup 1 3 and the inner bottom surface of the product and between the suction cup 2 6 and the inner side of the product can be sucked out. In this way, the suction cup 1 3 can fix the bottom of the product, and the suction cup 2 6 can generate adsorption force on the side wall of the product, which increases the contact area of ​​the device with the product, ensures the stability of the product fixation, and ensures the uniformity of the force applied by the device to the product, and ensures the stability and smoothness of the product movement during the demoulding process.

[0031] Furthermore, after the suction cup 1 3 and the suction cup 2 6 have finished fixing the product, the motor 19 is started, and the output shaft of the motor 19 rotates to drive the incomplete gear 18 to rotate. When the incomplete gear 18 contacts the complete gear 17, it will drive the complete gear 17 to rotate, so that the rotating shaft 15 and the wire roller 16 rotate, and then pull the pull rope 14. The pull rope 14 will pull the slide plate 12 and the slide bar 10 to move together, so that the mounting block 8 and the suction cup 2 6 move together. The movement of the suction cup 2 6 will pull the side wall of the product. Since the product is made of plastic and has a certain deformation ability, the side wall of the product will be slightly deformed under the pulling action and will be in contact with the inner side of the mold. A gap is generated between the incomplete gear 18 and the complete gear 17. When the incomplete gear 18 is not in contact with the complete gear 17, the product side wall is reset and the pull rope 14 is pulled under the elastic action of the product side wall itself, so that the rotating shaft 15 and the line roller 16 are reversed and reset. In this way, with the intermittent engagement of the incomplete gear 18 and the complete gear 17, the product side wall can be intermittently pulled, and then vibrates. In this way, a gap is generated between the product side wall and the mold during the demoulding process, so that the product can be quickly separated from the mold, reducing the difficulty of operation, and preventing the mold from having too much resistance to the product, causing the suction cup 3 to separate from the product, thereby ensuring the efficiency of the injection molding operation and the quality of the product.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
