[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1-Figure 6As shown, a bidirectional oblique sliding core-pulling structure of an injection mold for a central console of an automobile comprises a fixed mold base 1, a movable mold base 11 is overlapped at the top of the fixed mold base 1, a workpiece 4 is clamped at the top of the fixed mold base 1, an outer wall of the workpiece 4 is clamped at the bottom of the movable mold base 11, an upper core-pulling mechanism 2 is fixedly connected to the left end of the movable mold base 11, a lower core-pulling mechanism 3 is fixedly connected to the left end of the fixed mold base 1, the upper core-pulling mechanism 2 comprises a mounting plate 1 241, a right end of the mounting plate 1 241 is fixedly connected to the left end of the movable mold base 11 by bolts, and the lower core-pulling mechanism 3 comprises a mounting plate 2 341, a right end of the mounting plate 2 341 is fixedly connected to the left end of the fixed mold base 1 by bolts.
[0027] When the workpiece 4 needs to be cored, the upper core-pulling mechanism 2 and the lower core-pulling mechanism 3 cooperate with each other to complete two core-pulling operations at one time, which greatly improves the work efficiency.
[0028] like Figure 2-Figure 4 As shown, the left end of the mounting plate 241 is fixedly connected to the telescopic cylinder 24, the bottom of the front end of the mounting plate 241 is fixedly connected to the fixing plate 21, the right end of the fixing plate 21 is fixedly connected to the left end of the movable mold base 11 by bolts, the left and right parts of the top of the fixing plate 21 are fixedly connected to the switch 22, the rear end of the switch 22 is fixedly connected to the contact 1, the rear part of the top of the fixing plate 21 is movably connected to the trigger rod 23, and the switch 22 and the telescopic cylinder 24 are electrically connected.
[0029] Through the switch 22, the telescopic cylinder 24 is started, and the telescopic cylinder 24 contracts, so that the telescopic cylinder 24 drives the movable block 25 to move, and the movable block 25 drives the trigger rod 23 to move synchronously, so that the outer wall of the trigger rod 23 slides on the inner wall of the fixed plate 21. When the outer wall of the trigger rod 23 is in close contact with the contact 1 at the rear end of the switch 22, the switch 22 is closed at this time, which has the effect of automatic closing.
[0030] like Figure 2-Figure 4 As shown, the outer wall of the output end of the telescopic cylinder 24 passes through the outer wall of the movable mold base 11 and is clamped with a movable block 25. The left end of the movable block 25 is fixedly connected to the right end of the trigger rod 23. The outer wall of the movable block 25 is slidably connected to the inner wall of the movable mold base 11. A slide groove 26 is provided on the outer wall of the movable block 25. The inner wall of the slide groove 26 is slidably connected with an upper inclined slider 27. The bottom end of the upper inclined slider 27 is fixedly connected with an upper core pulling block 28. The outer wall of the upper core pulling block 28 is plugged into the inner wall of the workpiece 4.
[0031] When the telescopic cylinder 24 drives the movable block 25 to move, the upper inclined slider 27 slides on the inner wall of the slide groove 26. Since the slide groove 26 has a certain slope and the outer wall of the top of the upper core pulling block 28 is plugged into the inner wall of the movable mold base 11 and cannot move, when the movable block 25 slides to the left, the upper inclined slider 27 drives the upper core pulling block 28 to move upward, so that the outer wall of the upper core pulling block 28 is pulled out from the inner wall of the workpiece 4, thereby forming a groove and completing the core pulling operation.
[0032] like Figure 2 , Figure 5 , Figure 6 As shown, the left end of the mounting plate 341 is fixedly connected to the telescopic cylinder 34, the top of the mounting plate 341 is fixedly connected to the fixing plate 31, the right end of the fixing plate 31 is fixedly connected to the left end of the fixed mold base 1 by bolts, the left and right parts of the bottom end of the fixing plate 31 are fixedly connected to the switch 32, the rear end of the switch 32 is fixedly connected to the contact 2, the rear part of the bottom end of the fixing plate 31 is movably sleeved with the trigger rod 33, the switch 32 and the telescopic cylinder 34 are electrically connected, and the trigger rod 33 and the trigger rod 1 23 are of the same type.
[0033] The telescopic cylinder 34 is started by the switch 32, so that the telescopic cylinder 34 drives the connecting block 36 to move, and the connecting block 36 drives the trigger rod 33 to move synchronously, so that the outer wall of the trigger rod 33 slides on the inner wall of the fixing plate 31. When the outer wall of the trigger rod 33 is in close contact with the contact 2 at the rear end of the switch 32, the switch 32 is closed, achieving the effect of automatic closing.
[0034] like Figure 2 , Figure 5 , Figure 6 As shown, the outer wall of the output end of the telescopic cylinder 2 34 passes through the outer wall of the fixed die seat 1 and is clamped with a connecting block 36, the left end of the connecting block 36 is fixedly connected to the right end of the trigger rod 2 33, the outer wall of the connecting block 36 is slidably connected to the inner wall of the fixed die seat 1, the outer wall of the connecting block 36 is slidably connected to a fixed frame 35, the outer wall of the fixed frame 35 is fixedly connected to the bottom of the fixed die seat 1 by bolts, the outer wall of the connecting block 36 is provided with a slide groove 2 37, the inner wall of the slide groove 2 37 is slidably connected with a lower inclined slider 38, the top of the lower inclined slider 38 is fixedly connected with a lower core pulling block 381, and the outer wall of the lower core pulling block 381 is plugged into the inner wall of the workpiece 4.
[0035] When the telescopic cylinder 34 drives the connecting block 36 to move, the lower inclined slider 38 slides on the inner wall of the second slide groove 37. Since the second slide groove 37 has a certain slope, when the connecting block 36 moves to the left, the lower inclined slider 38 drives the lower core pulling block 381 to move downward synchronously, so that the inner walls of the lower inclined slider 38 and the lower core pulling block 381 slide on the outer wall of the limit block 39, so that the outer wall of the lower core pulling block 381 is no longer plugged into the inner wall of the workpiece 4, and the core pulling operation is completed.
[0036] like Figure 2 , Figure 5 , Figure 6 As shown, a limit block 39 is inserted into the inner wall of the lower inclined sliding block 38, and the outer wall of the limit block 39 is fixedly connected to the inner wall of the fixed mold base 1 by bolts.
[0037] The downwardly inclined slider 38 is fixed in the left-right direction by the limit block 39 so that the downwardly inclined slider 38 cannot move in the left-right direction but can only move in the up-down direction, thereby making the downwardly inclined slider 38 move more smoothly.
[0038] The working principle of the utility model is as follows: when the workpiece 4 is being processed and the core pulling is required, the telescopic cylinder 1 24 and the telescopic cylinder 2 34 are respectively started by the switch 1 22 and the switch 2 32, and the telescopic cylinder 1 24 drives the movable block 25 to slide on the inner wall of the movable die seat 11, and at the same time, the upper inclined slide block 27 slides on the inner wall of the slide groove 1 26. Since the slide groove 1 26 has a certain slope, and the outer wall of the top of the upper core pulling block 28 is plugged into the inner wall of the movable die seat 11 and cannot move left and right, when the movable block 25 slides to the left, the upper inclined slide block 27 drives the upper core pulling block 2 8 moves upward, so that the outer wall of the upper core-pulling block 28 is pulled out from the inner wall of the workpiece 4, thereby forming a groove and completing the core-pulling operation. When the movable block 25 moves, it drives the trigger rod 1 23 to move synchronously, so that the outer wall of the trigger rod 1 23 slides on the inner wall of the fixed plate 1 21. When the outer wall of the trigger rod 1 23 is in close contact with the contact 1 at the rear end of the switch 1 22, the switch 1 22 is closed at this time, and the telescopic cylinder 1 24 stops outputting, thereby stopping the movable block 25 from moving. At the same time, the telescopic cylinder 2 34 drives the connecting block 36 to slide on the inner wall of the fixed frame 35, thereby causing the lower inclined slide block 36 to slide on the inner wall of the fixed frame 35. 38 slides on the inner wall of the second slide groove 37. Since the second slide groove 37 has a certain slope, and the lower inclined slide block 38 is fixed in the left and right directions by the limit block 39, the lower inclined slide block 38 cannot move in the left and right directions, and can only move in the up and down directions. Therefore, when the connecting block 36 moves to the left, the lower inclined slide block 38 drives the lower core pulling block 381 to move downward synchronously, so that the inner wall of the lower inclined slide block 38 and the lower core pulling block 381 slides on the outer wall of the limit block 39, so that the outer wall of the lower core pulling block 381 is no longer plugged into the inner wall of the workpiece 4, completing the core pulling operation. When the switch 6 moves, the trigger rod 2 33 is driven to move synchronously, so that the outer wall of the trigger rod 2 33 slides on the inner wall of the fixed plate 2 31. When the outer wall of the trigger rod 2 33 is in close contact with the contact 2 at the rear end of the switch 2 32, the switch 2 32 is closed, and the telescopic cylinder 2 34 stops outputting, thereby stopping the connection block 36 from moving. As a result, two core pulling operations can be performed at the same time, which greatly speeds up the working efficiency of the core pulling. In the process of core pulling, the telescopic cylinder is used for control, which increases the stability of the core pulling process, ensures the quality of the core pulling, and greatly improves the user experience.
