AI Technical Summary
In the existing technology, it is difficult for humans to ensure that the demoulding angle is consistent each time during the demoulding process, resulting in unstable product quality and the undercut structure is easily damaged or cannot be demoulded.
A fully automatic plate removal mold is designed, which uses a rotatable opening and closing clamping claw to cooperate with the push plate. The hook-shaped structure of the clamping claw enters the groove and hooks the undercut structure. The rotation of the clamping claw is controlled by a robot to achieve automatic demoulding.
It ensures that undercut products can be automatically removed at the correct draft angle during each demoulding process, ensuring product quality and avoiding the uncertainty caused by manual intervention.

[0017] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will further illustrate the utility model in detail by combining with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0018] Please refer to Figure 1-Figure 3The utility model discloses a full -automatic plate's mould of taking, including the front mould embryo and rear mould embryo that can open and shut each other, the front mould embryo is equipped with the front mould core, the rear mould embryo is equipped with the rear mould core, the opening and shutting of front mould embryo and rear mould embryo drive the opening and shutting of front mould core and rear mould core, the front mould core and rear mould core mutually cooperate and show the cavity for injection molding reverse buckle product, be equipped with the push plate 1 for the product of ejecting on the rear mould core, and reverse buckle product is shaped on the surface of push plate 1, and the forming and ejecting process of injection product is prior art, and in this embodiment, no longer elaborate in detail.
[0019] The mould still includes the manipulator 2 for taking out product, and the manipulator 2 includes a plurality of rotatable opening and shutting clamping jaw 21, and a plurality of clamping jaw 21 are mutually surrounded and set on the periphery of push plate 1 a round.The opening and shutting of a plurality of clamping jaw 21 are mainly completed through a drive mechanism, and the drive mechanism can drive clamping jaw 21 to rotate and close to the direction of push plate 1 or open away from the direction of push plate 1, and the drive mechanism can include motor, gear and rack, for example, the motor drives rack movement through the gear deceleration, and the rack is connected with clamping jaw 21, and the meshing transmission of gear and rack makes each clamping jaw 21 rotate and realize mutual convergence and opening;Or use motor drive crank rotation, crank is connected with slider through connecting rod, and slider moves on fixed guide rail, and clamping jaw 21 is connected with slider, and the opening and shutting of clamping jaw 21 are realized through the rotation of crank and slider movement.This embodiment does not specifically limit drive mechanism, and the structure that can realize the rotation movement of drive clamping jaw 21 is all within the protection scope of this embodiment.
[0020] The push plate 1 is provided with a groove 11, and the undercut structure of the undercut product is formed in the groove 11. Specifically, the push plate 1 includes a horizontal block structure 12 and a vertical block structure 13, the vertical block structure 13 is arranged at the lower end of the horizontal block structure 12, both ends of the horizontal block structure 12 extend beyond both sides of the vertical block structure 13, and the groove 11 is arranged at the lower end of the extended part of the horizontal block structure 12. The undercut product is specifically formed on the surface of the horizontal block structure 12, and the undercut part is tightly inserted into the groove 11 along the horizontal block structure 12. When demolding, the front mold core and the rear mold core are separated, the push plate 1 pushes the product upwards, then each clamping jaw 21 moves towards the push plate 1, one end of the clamping jaw 21 is inserted into the groove 11 to hook the undercut structure of the product, and each clamping jaw 21 moves away from the push plate 1 to pull off the undercut structure of the product to complete demolding. Specifically, the tail end of the clamping jaw 21 is gradually bent into a hook-shaped structure from bottom to top, when demolding, the driving mechanism drives each clamping jaw 21 to rotate, so that the hook-shaped structure of each clamping jaw 21 is inserted into the groove 11, and at this time the hook-shaped structure of the clamping jaw 21 abuts against the undercut structure of the product, then the driving structure drives the clamping jaw 21 to rotate away from the push plate 1 again. Because the injection molded product has a certain elasticity, at this time the clamping jaw 21 abuts against the undercut structure of the product to gradually separate from the groove 11. In order to smoothly separate from the groove 11, the side of the groove 11 close to the edge of the horizontal block structure is arc-shaped with the transition surface of the edge of the horizontal block structure, which is opened along with the continuous rotation of the clamping jaw 21, that is, the undercut structure of the product can completely separate from the groove 11 to achieve the effect of demolding. Because the clamping jaw 21 is opened by rotating, the clamping jaw 21 also moves upward at the same time of rotating and opening, that is, in the process of the clamping jaw 21 driving the undercut structure of the product to separate from the groove 11, the clamping jaw 21 can also drive the entire product to move upward and separate from the push plate 1, thereby achieving the effect of full-automatic demolding. Preferably, in order for the hook-shaped structure of the clamping jaw 21 to smoothly extend into or out of the groove 11, the groove depth of the groove 11 is greater than the depth of the hook-shaped structure of the tail end of the clamping jaw 21, and the width of the groove 11 is greater than the thickness of the hook-shaped structure of the tail end of the clamping jaw 21.
[0021] For the installation position of the manipulator 2 on the mold, the manipulator 2 can be arranged above the front mold base or on the side of the position between the front mold base and the rear mold base. When the manipulator 2 is arranged above the front mold base, the rotating range of each gripper 21 needs to cover the whole operation area above the front mold base, or the front mold base and the rear mold base are designed as a detachable structure, and the front mold base is detached during demolding, so that the manipulator 2 can cooperate with the push plate 1 to demold directly. When the manipulator 2 is arranged on the side of the position between the front mold base and the rear mold base, a support or a boom needs to be added to fix the manipulator 2 on the side, and the manipulator 2 is added with transverse movement to make the gripper 21 cooperate with the push plate 1 to hook out the product reverse buckle, so as to achieve the effect of smooth demolding.
[0022] The above only is the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement or improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
