Technical Field

[0001] The utility model belongs to the technical field of injection molds, and more specifically, particularly relates to an injection mold with a buffer limiter component. Background Art

[0002] An injection mold is a mold used to produce injection molded products. It is also called an injection mold, plastic mold or plastic mold. It injects molten plastic or thermosetting plastic into the mold cavity through the injection molding process, and forms the desired product shape after cooling and solidification.

[0003] Since some current injection molds need to be manually installed on the frame by the staff during installation, position offset and error are prone to occur during the manual installation process. At this time, if the position of the injection mold is not checked and adjusted in time and the injection molding operation is carried out directly, it is easy to affect the product quality of the injection molded product and even cause damage to the mold.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an injection mold with a buffer limit component is provided, in order to achieve a more practical purpose. Utility Model Content

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] Example:

[0023] As attached Figure 1 To Attachment Figure 3 As shown:

[0024] The utility model provides an injection mold with a buffer limit assembly, comprising a first mold 1 and a second mold 2, a pair of first mounting seats 3 are symmetrically installed on both sides of the first mold 1, a connecting plate 4 is installed on one side of the first mounting seat 3, a first rubber pad 5 is installed on the connecting plate 4 on a side away from the first mounting seat 3, a plurality of infrared emitters 6 are installed on one side of the first mounting seat 3 at a position located on the peripheral side of the connecting plate 4, positioning rods 7 are installed at the four corners of one side of the first mold 1, a molding groove 8 is provided at the middle position of one side of the first mold 1, an ejection mechanism is installed inside the first mold 1, positioning grooves 9 are provided at the four corners of one side of the second mold 2, a first slider 10 is slidably installed in the positioning groove 9, a compression spring 11 is installed on one side of the first slider 10, and the other end of the compression spring 11 is connected to one side of the positioning groove 9, and buffer mechanisms are installed on both sides of the second mold 2.

[0025] The position and size of the positioning rod 7 match the position and size of the positioning groove 9 , so that the positioning rod 7 can enter the positioning groove 9 to position the first mold 1 and the second mold 2 .

[0026] Among them, the ejection mechanism includes a mounting groove 12, which is opened inside the first mold 1, and a second slider 13 is slidably installed inside the mounting groove 12. An ejection block 14 is installed on one side of the second slider 13, and one side of the ejection block 14 passes through one side of the first mold 1 and is slidably connected to the first mold 1. The movement of the second slider 13 drives the ejection block 14 to move, and the finished product after injection molding is ejected.

[0027] Among them, a threaded rod 15 is rotatably installed in the installation groove 12, and the threaded rod 15 passes through one side of the ejection block 14 and is threadedly connected to the ejection block 14. Through the rotation of the threaded rod 15, under the limiting action of the installation groove 12, the second slider 13 and the ejection block 14 move to eject the finished product after injection molding.

[0028] A motor 16 is installed on one side of the installation slot 12 , and the output end of the motor 16 is transmission-connected to the threaded rod 15 via a coupling. The motor 16 drives the threaded rod 15 to rotate, thereby driving the second slider 13 to move.

[0029] The buffer mechanism includes a pair of second mounting seats 17, which are symmetrically mounted on both sides of the second mold 2. A connecting groove 18 is provided on one side of the second mounting seat 17, and a photosensitive sensor 19 is mounted on one side of the connecting groove 18. A pair of second rubber pads 20 are mounted on the other two sides of the connecting groove 18 at positions close to the photosensitive sensor 19. The photosensitive sensor 19 can detect the received optical signal. When the first mold 1 and the second mold 2 are both in the correct position, during the movement of the first mold 1 to the second mold 2, the connecting plate 4 enters the connecting groove 18, so that the first rubber pad 5 and the second rubber pad 20 can fit together better, thereby causing the optical signal emitted by the infrared transmitter 6 to be blocked. The optical signal emitted by the infrared transmitter 6 is blocked, so that the optical signal emitted by the infrared transmitter 6 is less or cannot be transmitted to the photosensor 19. At this time, the optical signal detected by the photosensor 19 is within a reasonable error range, proving that the first mold 1 and the second mold 2 are in the correct position. When the positions of the first mold 1 and the second mold 2 deviate, the first rubber pad 5 cannot fit well with the second rubber pad 20, and cannot block the optical signal emitted by the infrared transmitter 6. At this time, the optical signal emitted by the infrared transmitter 6 is transmitted to the photosensor 19, and the photosensor 19 transmits the received optical signal to the external controller, so that the power supply controlling the movement of the first mold 1 is turned off and the staff is reminded to perform maintenance.

[0030] The position and size of the connection groove 18 match the position and size of the connection plate 4 , so that the connection plate 4 can enter the connection groove 18 .

[0031] Working principle of this embodiment: after the staff completes the installation of the first mold 1 and the second mold 2, the staff can control the movement of the first mold 1. When the first mold 1 and the second mold 2 are both in the correct position, during the movement of the first mold 1 to the second mold 2, the connecting plate 4 enters the connecting groove 18, so that the first rubber pad 5 and the second rubber pad 20 can fit together well, blocking the optical signal emitted by the infrared transmitter 6, thereby making the optical signal emitted by the infrared transmitter 6 less or unable to be transmitted to the photosensitive sensor 19. At this time, the optical signal detected by the photosensitive sensor 19 is within a reasonable error range, proving that the first mold 1 and the second mold 2 are in the correct position. When the positions of the first mold 1 and the second mold 2 deviate, the first rubber pad 5 cannot fit together well with the second rubber pad 20, and cannot block the optical signal emitted by the infrared transmitter 6. At this time, the optical signal emitted by the infrared transmitter 6 is less. The signal is transmitted to the photosensitive sensor 19, and the photosensitive sensor 19 transmits the received optical signal to the external controller, so that the power supply controlling the movement of the first mold 1 is turned off and the staff is reminded to perform maintenance. After the installation is completed, the injection molding work can be carried out. During the movement of the first mold 1, the positioning rod 7 first enters the positioning groove 9. When the positioning rod 7 continues to move, one end of the positioning rod 7 first pushes the first slider 10 to move and squeezes the compression spring 11, so that the compression spring 11 is deformed and the kinetic energy is absorbed, so as to achieve buffering of the first mold 1, reduce the damage caused by the direct collision between the first mold 1 and the second mold 2, and extend the service life of the first mold 1 and the second mold 2. After the injection molding is completed, the staff controls the first mold 1 to stay away from the second mold 2. At this time, the motor 16 is turned on, and the motor 16 drives the threaded rod 15 to rotate. Under the limiting action of the installation groove 12, the second slider 13 and the ejection block 14 move to eject the finished product after the injection molding is completed.
