Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figures 1-4As shown, the utility model is an injection molding tray mold, comprising a lower fixing plate 1 and an upper fixing plate 2. The top of the lower fixing plate 1 is fixedly connected to a mold foot 3, and one side of the mold foot 3 is fixedly connected to a fixed platform 4. The top of the fixed platform 4 is provided with a knocking promotion mechanism 5. The knocking promotion mechanism 5 includes a fixing plate 51 fixedly connected to the top of the fixed platform 4. The front of the fixing plate 51 is fixedly connected to a limit rod 52, a connecting plate 53 and a motor 54. The motor 54 is electrically connected to an external power supply and is controlled by an external program. The surface of the limit rod 52 is rotatably connected to a transmission arm 55. The front of the connecting plate 53 is fixedly connected to a limit slot 56. A connecting bar 57 is slidably connected to the limit slot 56. The left side of the connecting bar 57 is fixedly connected to a spring rod 58. The spring rod 58 acts as a buffer to prevent damage caused by rigid contact. The left end of the spring rod 58 is fixedly connected to a knocking plate 59. The knocking plate 59 is made of copper with moderate hardness, good anti-adhesion and wear resistance, and has a certain knocking hardness to ensure that the equipment is not excessively damaged. The front of the connecting strip 57 is fixedly connected to a connecting shaft 510, the output end of the motor 54 is fixedly connected to a rotating disk 511, and the front of the rotating disk 511 is fixedly connected to a rotating shaft 512. By knocking on the promotion mechanism 5, the vibration generated by the knocking helps to separate the adhesion between the plastic part and the mold, making it easier for the plastic part to be removed from the mold, helping the plastic part to be quickly demolded from the mold, shortening the production cycle, and improving production efficiency. The elastic characteristics of the spring rod 58 can provide a buffering force when knocking to prevent damage.
[0022] Four guide pillars 6 are fixedly connected to the top of the mold foot 3, and guide sleeves 7 are slidably connected to the surfaces of the four guide pillars 6. An upper mold 8 is fixedly connected between the four guide sleeves 7.
[0023] The inner wall of the upper fixing plate 2 is fixedly connected with a glue injection port 9, and the glue injection port 9 is connected to a heating tube 10. The heating tube 10 is electrically connected to an external power supply and is controlled by an external program. The heating tube 10 is a common heating device. Its working principle is to convert electrical energy into thermal energy. It is a prior art and will not be described in detail in this article.
[0024] A mold plate 11 is located at the bottom of the upper fixing plate 2, and multiple ejector pins 12 are fixedly connected to the top of the mold foot 3. The ejector pins 12 are a key component of the injection tray mold, helping to eject the product from the mold after injection molding, thereby achieving product demolding. A lower mold 13 is located above the mold foot 3.
[0025] A tray component body 14 is provided between the upper die 8 and the lower die 13 .
[0026] The rotating shaft 512 and the connecting shaft 510 are both adapted to fit between the transmission arm 55 .
[0027] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0028] The working principle of the present invention is as follows: First, the upper mold 8 and the lower mold 13 are closed to form a closed mold cavity, and then the molten plastic material is injected from the injection port 9. Then, the heating tube 10 is immediately started to heat the material continuously as it flows through. After the injection molding is completed, the molding is completed and the mold is allowed to cool down, so that the plastic is cooled and solidified in the mold cavity. When the plastic is completely cooled and solidified, the motor 54 is started to drive the rotating disk 511 at the output end to rotate. When the rotating disk 511 rotates, the rotating shaft 512 on it drives the transmission arm 55, so that the transmission arm 55 rotates back and forth on the surface of the limit rod 52 with the limit rod 52 as the center of the circle within a range of 90 degrees. While the transmission arm 55 moves, it drives the connecting bar 57 through the connecting shaft 510, so that the connecting bar 57 moves back and forth on the limit groove 56. As the connecting bar 57 reciprocates left and right, it drives the striking plate 59 through the spring rod 58, allowing the striking plate 59 to continuously strike the lower mold 13, promoting its removal. At the same time, the elastic force of the spring rod 58 provides a buffer. The mold is then opened, and finally, the ejector pin 12 is activated to lift the finished tray part body 14. At this point, the finished tray can be removed.
