Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1-5, a mold structure for facilitating demolding, comprising: a first slider 100 horizontally movable, the first slider 100 being provided with an inclined chute 110; the second sliding block 200 is movably arranged in the inclined sliding groove 110, when the first sliding block 100 moves horizontally, the second sliding block 200 can be driven to move through the inclined sliding groove 110, and the second sliding block 200 is provided with a first forming block 210; and a third slider 300 which is vertically movable, wherein the first molding block 210 and the third slider 300 are vertically arranged in a corresponding manner, and a molding cavity 600 is formed between the third slider 300 and the first molding block 210.
After the workpiece is processed, the workpiece has a strip-shaped main body and at least one flanging structure located on the main body, one flanging structure of the workpiece is located in the forming cavity 600 (the flanging structure of the workpiece in the figure is overlapped with the forming cavity 600), and the first forming block 210 and the third slide block 300 clamp the flanging structure, so that the second slide block 200 cannot be simply and horizontally pulled outwards, and the difficulty in demolding is very high.
In terms of the movement manner of each slide block, the first slide block 100 can move horizontally, the second slide block 200 can move obliquely downward relative to the oblique slide groove 110, and the horizontal movement of the first slide block 100 can be converted into the vertical movement of the second slide block 200 by the action of the oblique slide groove 110, so that the second slide block 200 moves downward relative to the workpiece, and the third slide block 300 can move upward and downward.
Preferably, since the second slider 200 is linked with the first slider 100, and at the time of demolding, the third slider 300 moves down to leave a space, which is located below the burring structure, therefore, the flanging structure can be elastically deformed by using the space, and then the first sliding block 100 moves horizontally outwards, and the second sliding block 200 can move relative to the first sliding block 100, it is important to point out that the second sliding block 200 slides downwards along the inclined sliding chute 110 in an inclined manner in the opposite direction, at this time, the second sliding block 200 moves downwards relative to the workpiece, the second sliding block 200 pushes the flanging structure of the workpiece to deform towards the space below, thereby, the first forming block 210 is moved to the lower side of the flange structure, and as the first slider 100 is moved further, it can pull second slider 200 horizontal migration to make first forming block 210 pull out, and then smooth realization drawing of patterns.
In summary, when the workpiece is demolded, the third slider 300 moves downward to make the springback space available, when the first slider 100 moves horizontally, the second slider 200 can move obliquely downward in the opposite direction, and moves downward relative to the workpiece, and then the first slider 100 pulls the second slider 200 to horizontally pull away, so that the workpiece can be demolded smoothly.
As shown in fig. 1, 2 and 3, in addition to the above embodiment, the present invention further includes a fourth slider 400, the third slider 300 is located between the fourth slider 400 and the first slider 100, the fourth slider 400 is linked with the third slider 300, and the fourth slider 400 moves horizontally toward the first slider 100 when the third slider 300 moves downward.
Preferably, the fourth slider 400 can move left and right, when the mold is closed, the left and right side surfaces of the third slider 300 are respectively in contact connection with the side surfaces of the fourth slider 400 and the side surfaces of the first slider 100, and when the mold is opened, the third slider 300 firstly moves downward, so that a certain space is left between the first slider 100 (the second slider 200) and the fourth slider 400, and the workpiece flanging structure can deform and move towards the space, thereby facilitating the demolding.
It is to be added that, in the actual structure, because the workpiece has a plurality of flanging structures, the fourth slider 400 is required to form other flanging structures, and because the fourth slider 400 is linked with the third slider 300, the third slider 300 can drive the fourth slider 400 to translate when descending, so that the fourth slider 400 can be conveniently demoulded.
As shown in fig. 1, 3, 4 and 5, in addition to the above embodiment, a slider holder 500 is connected to the first slider 100, a set screw 510 is provided on the slider holder 500, a spring 220 is provided on the second slider 200, and the spring 220 is connected to the set screw 510.
Preferably, the second slider 200 can move in the inclined sliding groove 110, the limit screw 510 is fixed to the slider holder 500, and the spring 220 is connected to the limit screw 510, so the slider holder 500 can pull the second slider 200 through the spring 220, thereby limiting the moving stroke of the second slider 200, in actual operation, the first slider 100 moves horizontally, the second slider 200 moves obliquely and downwards in the inclined sliding groove 110, at this time, the spring 220 is pulled apart, when the second slider 200 moves to a certain stroke, the pulling force of the spring 220 becomes large, thereby pulling the second slider 200, so that the second slider 200 moves horizontally together with the first slider 100, and further the second slider 200 is pulled outwards.
Therefore, the slider holder 500 is connected to the second slider 200 through the limit screw 510 and the spring 220, so that the second slider 200 can move horizontally after moving downward a certain distance relative to the workpiece when the first slider 100 moves horizontally.
