When choosing a lamp, you should pay attention to whether the quality and performance of the lamp chassis meet the requirements. The molding of the lamp chassis usually adopts the in-mold molding method. In this way, the lamp chassis with high precision and good consistency can be produced quickly and efficiently.
[0003] Stamping is a common and effective method for manufacturing lamp chassis.

DETAILED DESCRIPTION

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an in-mold forming device for a lamp chassis, comprising a base 1, a mold 8 is fixedly connected to the top of the base 1, an ejection plate 14 is slidably connected to the inside of the base 1, a ring array of limit rods 15 is fixedly connected to the bottom of the ejection plate 14, the outer wall of the limit rod 15 is slidably connected to the inside of the base 1, and a spring 2 16 is sleeved on the outer wall of the limit rod 15, one end of the spring 2 16 is fixedly connected to the bottom wall of the ejection plate 14, and the other end of the spring 2 16 is fixedly connected to the inner wall of the base 1, and the top of the base 1 is fixed A slide bar 5 is connected, a top plate 6 is fixedly connected to the top of the slide bar 5, a slide block 4 is slidably connected to the outer wall of the slide bar 5, a cylinder 7 is fixedly connected to the top of the top plate 6, the top of the slide block 4 is fixedly connected to the output end of the cylinder 7, a mold 2 11 is fixedly connected to the inside of the slide block 4, a push rod 9 is slidably connected to the inside of the slide block 4, a spring 10 is sleeved on the outer wall of the push rod 9, one end of the spring 10 is fixedly connected to one side of the outer wall of the push rod 9, and the other end of the spring 10 is fixedly connected to the top of the slide block 4;
[0033] Specifically, when the lamp chassis is stamped and formed, the cylinder 7 first pushes the sliding block 4, so that the mold 2 11 inside the sliding block 4 cooperates with the mold 1 8 for stamping and forming. When the mold 2 11 is pressed down, it is necessary to overcome the force of the spring 2 16 to press the ejector plate 14 down. The buffering of the spring 2 16 can ensure the stability of the molding process. When the mold 2 11 is lifted, the ejector plate 14 will be lifted under the action of the spring 2 16, so that the molded lamp chassis is separated from the mold 1 8. As the sliding block 4 continues to be lifted, the ejector rod 9 will resist the top plate 6 and be pressed down by the top plate 6 to overcome the force of the spring 10. This design enables the ejector rod 9 to smoothly separate the lamp chassis from the mold 2 11, thereby realizing the automatic separation of the lamp chassis.

[0035] Specifically, a control console 3 is provided on one side of the base 1, and the console 3 can be used to accurately control the stamping of the lamp chassis. At the same time, heat dissipation holes 2 are provided on the base 1 to facilitate heat dissipation of the base 1, thereby increasing the service life of the device.
[0036] Reference Figure 2 , Figure 3 and Figure 4 , the sliding block 4 is internally threadedly connected with a threaded rod 13 of an annular array, one end of the threaded rod 13 is fixedly connected with a handle 12, the end face of the threaded rod 13 fits with the outer wall of the mold 2 11, the top of the base 1 is fixedly connected with a fixed column 22, the outer wall of the fixed column 22 is slidably connected to the inside of the mold 1 8, the base 1 is internally rotatably connected with a rotating shaft 20, one side of the outer wall of the rotating shaft 20 is fixedly connected with a rotating plate 23, an annular array of card slots 21 are provided inside the mold 1 8, the outer wall of the rotating plate 23 is rotatably connected with a connecting rod 24 of an annular array, one side of the connecting rod 24 is rotatably connected with a card block 25, the outer wall of the card block 25 is slidably connected to the inside of the fixed column 22, the outer wall of the card block 25 is slidably connected to the inside of the card slot 21, the bottom end of the rotating shaft 20 is fixedly connected with a worm gear 18, the base 1 is internally rotatably connected with a crank 17, one end of the crank 17 is fixedly connected with a worm 19, and the outer wall of the worm 19 is meshed with the outer wall of the worm gear 18;
[0037] Specifically, when replacing the mold, first, for mold 2 11, it can be placed inside the sliding block 4, and by using the handle 12 to tighten the threaded rod 13, the threaded rod 13 can fasten the mold 2 11 due to the self-locking characteristics of the thread, thereby facilitating the replacement and fixation of the mold 2 11. For the replacement of mold 1 8, first place the mold 1 8 on the fixing column 22 at the top of the base 1, and then drive the rotation of the worm 19 by the crank 17, the worm 19 will drive the worm wheel 18 to rotate, and the worm wheel 18 and the worm 19 are locked, so that the mechanism is self-locking. Lock, then, the worm gear 18 drives the rotation of the rotating plate 23 through the rotating shaft 20. The rotation of the rotating plate 23 will drive the movement of the connecting rod 24, so that the connecting rod 24 pushes the block 25 to slide out from the inside of the fixed column 22 and insert it into the slot 21 inside the mold 8.

This design realizes the convenience and speed of mold replacement through simple and effective mechanical operation. The operator does not need additional tools and can complete the mold replacement through manual operation, saving time and labor costs.
[0038] Working principle: When the lamp chassis is stamped and formed, the cylinder 7 will push the sliding block 4, and the mold 2 11 inside the sliding block 4 will cooperate with the mold 1 8 for stamping and forming.

When the sliding block 4 is continuously lifted, the ejector rod 9 will resist the top plate 6, so that the top plate 6 overcomes the force of the spring 10 and presses down, so that the lamp chassis inside the mold 2 11 is separated by the ejector rod 9, and the lamp chassis can be automatically separated when the mold is replaced. , mold 2 11 can be placed inside the sliding block 4, and then the threaded rod 13 is tightened by the handle 12, so that the threaded rod 13 presses the mold 2 11, so that the mold 2 11 can be replaced and fixed. When the mold 18 is replaced, the mold 18 can be placed on the fixed column 22 at the top of the base 1, and then the crank 17 drives the worm 19 to rotate, and the worm 19 can drive the worm wheel 18 to rotate, and then the worm wheel 18 drives the rotating plate 23 to rotate through the rotating shaft 20, and the rotating plate 23 can drive the connecting rod 24 to move, so that the connecting rod 24 pushes the block 25 to slide out of the fixed column 22 and insert it into the slot 21 inside the mold 18, so that the mold 18 can be replaced and fixed.
