[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5As shown, this application provides a precision molding device for robot plastic components, including: a pressure locking assembly 1, which includes a pressure frame 101, two pressure frames 101 are symmetrically arranged, a driving pressure arm 102 is symmetrically rotatably arranged on the inner side of the bottom end of the pressure frame 101, a receiving connecting rod 105 is fixedly arranged on one side of the other end of the driving pressure arm 102 that is close to each other, and a rotating connecting plate 107 is fixedly arranged on one side of the receiving connecting rod 105 that is close to each other; and a fixed mold assembly 2, which is arranged on one side of the top end of the rotating connecting plate 107, and includes a fixed locking shell 201. The inner side of 01 is provided with a receiving groove 2011, and a sliding block 204 is slidably arranged inside the receiving groove 2011. The fixed locking shell 201 is fixedly arranged on one side of the rotating connecting plate 107. The bottom end of the sliding block 204 is fixedly arranged with a pressure pad 205. The injection mold 3 is arranged at the top of the pressure frame 101. Side locking blocks 301 are fixedly arranged on both sides of the injection mold 3. A notch 3011 is opened on the side of the side locking blocks 301 that is far apart from each other. The fixed mold assembly 2 enters the notch 3011 and locks the injection mold 3 under the rotation of the rotating connecting plate 107.

[0028] After adopting the above technical solution, when the lower injection mold 3 is placed at the top of the pressure frame 101, the pressure frame 101 will descend due to the weight of the lower injection mold 3 itself until it contacts the support platform 109, at which point it will stop, indicating that the lower injection mold 3 has been locked. As the pressure frame 101 descends, the included angle between the two driving arms 102 will gradually increase, simultaneously causing the receiving connecting rod 105 to rotate. The rotation of the receiving connecting rod 105 causes the rotating connecting plate 107 to flip, thus enabling... The moving and fixed locking housing 201 enters the notch 3011, while the pressure pad 205 first contacts the inner side of the notch 3011 and compresses, increasing the downward pull of the slider 204 in the groove on the side locking block 301. This allows the slider 204 and the pressure pad 205 in the groove to gradually grip the side locking block 301 until the fixed locking housing 201 is completely inserted into the notch 3011. At this point, the effect of locking the injection mold 3 is achieved, thereby realizing rapid locking, improving the efficiency of changing the injection mold 3, and thus improving the injection molding efficiency of robot components.

[0029] Among them, a sliding block 106 is rotatably provided on the outer side of the connecting rod 105. There are two sliding blocks 106. A guide slide 108 is slidably provided on the outer side of the sliding block 106. A support platform 109 is fixedly provided on the side of the guide slide 108 that is far away from each other. The support platform 109 is used to support the injection mold 3.

[0030] In an alternative embodiment, as the angle between the driving arms 102 gradually increases, the receiving link 105 rotates inside the sliding block 106, and at the same time, the two sliding blocks 106 move away from each other, thereby realizing the flipping of the connecting plate 107 and locking the injection mold 3.

[0031] It should be noted that a connecting horizontal plate 103 is fixedly installed between the pressure frames 101, and a pressure spring 104 is fixedly installed at the bottom end of the connecting horizontal plate 103. The pressure spring 104 is fixedly installed at the top end of the guide slide 108. A threaded sleeve 203 is fixedly installed at the top end of the slider 204 in the groove. A screw 202 is threadedly connected to the inner side of the threaded sleeve 203. A bracket 206 is rotatably installed on the outer side of the screw 202. The bracket 206 is fixedly installed at the top end of the rotating connecting plate 107. The pressure pad 205 is made of rubber.

[0032] In an optional embodiment, the connecting plate 103 is configured to connect the two pressure frames 101 and to connect the pressure spring 104, so that after the injection mold 3 at the top of the pressure frame 101 is removed, the pressure frame 101 can return to its original position by the rebound force of the pressure spring 104, which is convenient for the next installation.

[0033] When unlocking the lower injection mold 3, rotating the screws 202 on both sides allows the screw sleeve 203 to rise. The screw sleeve 203 can then drive the slider 204 and pressure pad 205 in the groove to enter the inner side of the receiving groove 2011 and slide upward. The pressure pad 205 can then leave the notch 3011. Then, pull the connecting plate 107 to both sides so that the pressure frame 101 can rise. At the same time as unlocking the lower injection mold 3, the connecting plate 103 is lifted. At this time, the lower injection mold 3 can be removed, achieving the effect of quick disassembly.

[0034] For example, auxiliary locking components 4 are symmetrically arranged on both sides of the lower injection mold 3 and the upper injection mold 5. Four sets of auxiliary locking components 4 are provided. Each auxiliary locking component 4 includes a guide pin 401 and a slot 402. A pair of sliding plates 403 are symmetrically slidably arranged on the top of the slot 402. A return spring 405 is fixedly arranged on the side of the sliding plates 403 that is close to each other. Two return springs 405 are fixedly arranged on the inner side of the top of the slot 402. A pair of return springs 405 are fixedly arranged on the side of the sliding plates 403 that is far apart from each other. A locking post 404 is fixedly installed at the top of the upper injection mold 5. A hydraulic rod 501 is connected to the hydraulic rod 501. Both sides of the lower injection mold 3 and the upper injection mold 5 are provided with fitting grooves. The guide post 401 is fixedly installed in the fitting grooves on both sides of the upper injection mold 5. The slot 402 is provided in the fitting grooves on both sides of the lower injection mold 3. The slot 402 is fixedly installed at the top of the support platform 109. The inner side of the fitting grooves on both sides of the lower injection mold 3 is symmetrically provided with column grooves 302. The locking post 404 is inserted into the column grooves 302.

[0035] In an optional embodiment, when the upper injection mold 5 and the lower injection mold 3 are closed, the four guide pins 401 will simultaneously enter the fitting groove on one side of the lower injection mold 3. When the guide pins 401 contact the top of the sliding plates 403, the sliding plates 403 will move away from each other to both sides. It should be noted that the bottom ends of the guide pins 401 are sloped, which facilitates the two sliding plates 403 moving away from each other during the descent. At the same time, the two return springs 405 are extended, and the locking pins 404 will be driven to move into the pin grooves 302. Thus, through the cooperation of the locking pins 404 and the pin grooves 302, the lower injection mold 3 is further locked, improving the accuracy of the lower injection mold 3 and the upper injection mold 5 when they are closed, thereby improving the quality of the injection molded parts.

[0036] When the upper injection mold 5 rises and the guide pin 401 moves away from the slide plate 403, the return force of the reset spring 405 allows the locking pin 404 to exit the pin slot 302, thus no longer locking the lower injection mold 3.
