Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, and specifically relates to a rapid demoulding assembly with an inclined ejector structure. Background Technique

[0002] Referring to the patent with the title: A mold with a rapid demoulding assembly (Patent Publication No.: CN220923201U, Patent Publication Date: May 10, 2024), which includes a mold shell. One side of the mold shell is provided with a mold cavity. The inner wall of the mold cavity is provided with a bottom cavity. The inner wall of the bottom cavity is connected with a first fixing rod and a second fixing rod. The inner wall of the bottom cavity is connected with a motor. The upper side of the motor is connected with a lead screw. The upper side of the first fixing rod is connected with an inclined rod. There are two inclined rods, and the two inclined rods are symmetrically arranged. The outer wall of the lead screw is sleeved with a threaded block. One side of the threaded block is connected with a first fixing block. By driving the lead screw to rotate through the motor, the threaded block makes a linear movement on the lead screw under the action of the first fixing block, the second fixing block and the cross bar, so as to drive the slider to slide on the inclined rod through the second fixing block, making the slider and the threaded block move synchronously, and then driving three vertical rods and the rectangular blocks connected to the vertical rods to move, and ejecting the formed workpiece for demoulding.

[0003] Based on the above document: After the existing mold is injection-molded, the workpiece needs to be taken out of the mold. The traditional demoulding method is manual demoulding. However, due to the high temperature during the injection-molding process, the formed workpiece is still likely to stick firmly in the mold groove after cooling, making the demoulding work difficult and inefficient. In the above technical solution, the lead screw is driven to rotate through the motor, and then the threaded block makes a linear movement on the lead screw under the action of the first fixing block, the second fixing block and the cross bar, so as to drive the slider to slide on the inclined rod through the second fixing block, making the slider and the threaded block move synchronously, and then driving three vertical rods and the rectangular blocks connected to the vertical rods to move, and ejecting the formed workpiece for demoulding. However, in the above technical solution, when encountering a special-shaped mold, there is a lack of an inclined ejector structure, so that the rapid demoulding operation cannot be carried out on the special-shaped mold. Therefore, the utility model provides a rapid demoulding assembly with an inclined ejector structure. Summary of the Utility Model

Detailed Embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides two technical solutions:

[0026] Embodiment 1

[0027] A rapid demolding assembly with an inclined top structure, including a mold table 1, a lower template 2 fixedly connected to the top of the mold table 1, an injection molding groove 3 opened on the top of the lower template 2, an inclined top mechanism 4 provided inside the lower template 2, and a demolding mechanism 5 provided at the bottom of the inner cavity of the mold table 1. The demolding mechanism 5 includes:

[0028] A demolding assembly 51, including a sliding plate 511 slidably arranged inside the mold table 1. A fixing block 512 is fixedly connected to the bottom of the sliding plate 511. A rolling wheel 513 is rotatably connected inside the fixing block 512. A connecting plate 514 is fixedly connected to the top of the sliding plate 511. A connecting groove 515 is opened on the inner surface of the connecting plate 514. A top rod 516 is fixedly connected to the center of the top of the connecting plate 514. The top rod 516 slides on the top of the mold table 1.

[0029] A driving assembly 52, arranged on the right side of the mold table 1;

[0030] A reset assembly 53, arranged at the top of the inner cavity of the mold table 1. The driving assembly 52 includes a driving cylinder 521 installed on the right side of the mold table 1. The driving cylinder 521 is communicated with an external air source through an air pipe. The left side of the driving cylinder 521 is fixedly connected to a driving plate 522 through a piston rod. A limiting block 523 is fixedly connected to the bottom of the driving plate 522. The top of the driving plate 522 is in contact with the surface of the rolling wheel 513. Driven by the driving cylinder 521, when the driving plate 522 slides, it drives the top rod 516 to slide upward on the inner surface of the ejection groove 7, and the mold formed on the surface of the lower template 2 is ejected by the top rod 516 to achieve rapid demolding.

[0031] Embodiment 2

[0032] The main difference from Embodiment 1 is:

[0033] A rapid demoulding assembly with an inclined ejector structure. In the reset assembly 53, it includes a reset rod 531 installed at the top of the inner cavity of the mold table 1 and a reset spring 532. The reset spring 532 makes the surface of the rolling wheel 513 always fit against the top of the driving plate 522. The surface of the reset rod 531 is slidably connected to the inside of the sliding plate 511. The bottom end of the reset spring 532 is fixedly connected to the top of the sliding plate 511. The bottom of the inner cavity of the mold table 1 is fixedly connected with a limit slide rail 6, and the limit slide rail 6 is used to limit the driving plate 522. The surface of the limit slide rail 6 is slidably connected to the inside of the limit block 523. An ejection groove 7 is opened inside the lower template 2, and the inner surface of the ejection groove 7 is slidably connected to the surface of the ejection rod 516. Symmetrically arranged inclined slide grooves 8 are opened inside the lower template 2. The inclined ejector mechanism 4 includes an inclined ejector rod 41 slidably arranged on the inner surface of the inclined slide groove 8. The inclined ejector rod 41 slides on the top of the mold table 1. The bottom end of the inclined ejector rod 41 is fixedly connected with a connecting block 42. The connecting block 42 is a cylindrical block, and the surface of the connecting block 42 is slidably connected to the inner surface of the connecting groove 515. By providing the inclined ejector mechanism 4, when the ejection rod 516 ejects the mold, the inclined ejector rod 41 simultaneously slides obliquely upward on the inner surface of the inclined slide groove 8, so that the convex structure on the surface of the mold is separated from the mold notch inside the inclined ejector rod 41, thereby realizing the rapid demoulding of the special-shaped mold. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] After the mold injection is completed, by starting the driving cylinder 521, the piston rod and the driving plate 522 slide synchronously to the left. The sliding of the driving plate 522 makes the limit block 523 slide on the surface of the limit slide rail 6. And because the top of the driving plate 522 is designed with an inclined surface, when the sliding plate 511 slides, the rolling wheel 513 rolls on the top of the sliding plate 511, so that the rolling wheel 513, the fixed block 512, the sliding plate 511, the connecting plate 514 and the ejection rod 516 slide upward synchronously, making the sliding plate 511 slide on the surface of the reset rod 531, and the reset spring 532 starts to contract. The ejection rod 516 slides on the inner surface of the ejection groove 7, and the formed mold is ejected through the ejection rod 516. At the same time, when the connecting plate 514 slides upward, it will drive the inclined ejector rod 41 to slide on the inner surface of the inclined slide groove 8. While the inclined ejector rod 41 slides, the connecting block 42 installed at its bottom end slides on the inner surface of the connecting groove 515, making the inclined ejector rod 41 slide obliquely upward, so as to facilitate the formed mold to slide out of the mold notch opened inside the inclined ejector rod 41 and realize the rapid demoulding operation.
