[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-3 , which is the first embodiment of the utility model, provides an injection mold positioning structure for lamp processing, the injection mold positioning structure for lamp processing comprises a mold body 1, an upper mold 2 mounted on the top of the mold body 1, positioning members 4 are arranged on both sides of the mold body 1, a base 3 is movably connected to the bottom of the positioning member 4, and an adjusting member 5 is arranged inside the base 3 and inside the positioning member 4;

[0026] The positioning member 4 includes a movable seat 41 located on the surface of the base 3, a fixed block 42 is fixedly connected to the surface of the movable seat 41, the mold body 1 is located on the surface of the fixed block 42, a groove 43 is opened inside the fixed block 42, the grooves 43 are symmetrically arranged on both sides of the fixed block 42, and the two groups of grooves 43 are fixedly connected to the inside of the positioning shaft 44, the mold body 1 is connected to the upper mold 2 by an electric push rod, and the positioning member 4 is provided with two groups.

[0027] A positioning rod 45 is movably sleeved on the surface of the positioning shaft 44, one end of the positioning rod 45 and the end away from the positioning shaft 44 is fixedly connected to a bolt 46, a nut 47 is threadedly connected to the surface of the bolt 46, the other end of the positioning rod 45 and the end away from the bolt 46 is fixedly connected to a ring, and the positioning rod 45 is connected to the positioning shaft 44 via the ring.

[0028] Positioning grooves 49 are provided on both sides of the mold body 1. The positioning rod 45 is located inside the positioning groove 49 and is movably connected thereto. The nut 47 is located at the top of the positioning groove 49. The positioning rod 45 can be flipped to ninety degrees toward the end away from the fixed block 42. The diameter of the nut 47 is larger than the diameter of the positioning groove 49, which can facilitate the positioning of the mold body 1. After the positioning rod 45 is fitted with the positioning groove 49, the nut 47 can be turned to make it located at the top of the positioning groove 49 to achieve the purpose of positioning the mold body 1.

[0029] The bottom of the movable seat 41 is fixedly connected with a slider 48 . The sliders 48 are provided in two groups and are symmetrically arranged. The sliders 48 are connected to the adjusting member 5 .

[0030] During use, the mold body 1 is installed on the surface of the fixed block 42, and then the positioning rod 45 is pushed to make it flip around the positioning axis 44 as the center point until the positioning rod 45 is in contact with the positioning grooves 49 opened on both sides of the mold body 1, and then the nut 47 is directly twisted to make it rotate along the surface of the bolt 46, and slowly move toward the surface of the mold body 1 and the positioning groove 49 until the nut 47 is located in the positioning groove 49 and the surface of the mold body 1, and the bottom of the nut 47 is in contact with the surface of the mold body 1. Since the diameter of the nut 47 is larger than the diameter of the positioning groove 49, when the bottom of the nut 47 contacts the positioning groove 49, it will not directly slide into the inside of the positioning groove 49. When the bottom of the nut 47 is stuck with the top of the positioning groove 49 and the top of the mold body 1, the operation can be completed. This method is simple to operate and is convenient for positioning the mold body 1. When adjusting the operation, only the nut 47 needs to be turned. Compared with the positioning pin method, the bolt 46 fixing structure may reduce the number of required parts, and the bolt 46 fixing structure is relatively simple and easy to maintain. If replacement or maintenance is required, the operation is relatively convenient and quick.

[0031] Example 2

[0032] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0033] The adjusting member 5 includes a motor 51 installed inside the base 3, and the output end of the motor 51 is fixedly connected to a bidirectional screw 52. The bidirectional screw 52 is located inside the base 3, and the other end thereof is rotatably connected to the base 3. The bidirectional screw 52 is used to drive the positioning member 4 to move to adapt to mold bodies 1 of different lengths.

[0034] The adjusting member 5 further comprises a slide bar 53 fixed inside the base 3 . The slide bar 53 is located on one side of the bidirectional screw rod 52 . The slide bar 53 can make the movement of the two groups of positioning members 4 more stable.

[0035] The bidirectional screw 52 and the slide bar 53 are both located inside the slider 48 . The bidirectional screw 52 is threadedly connected to the slider 48 . The slide bar 53 is movably sleeved to the slider 48 . The two groups of sliders 48 are connected to the bidirectional screw 52 and the slide bar 53 respectively.

[0036] During use, the motor 51 can be started according to the length of the mold body 1 to drive the bidirectional screw 52 to rotate. Since the screw 52 is threadedly connected to the slider 48, when it rotates, the slider 48 will drive the two groups of positioning parts 4 to move closer to or away from each other. In this process, the other group of sliders 48 of the positioning part 4 will slide along the surface of the slide bar 53, thereby improving the stability of the positioning part 4 when moving. By setting the bidirectional screw 52, ​​it can adapt to mold bodies 1 of different lengths and perform positioning operations on them. By adjusting the bidirectional screw 52, ​​the distance between the two groups of positioning parts 4 can be quickly and conveniently adjusted to adapt to mold bodies 1 of different lengths, thereby shortening the adjustment time for processing car lights and improving production efficiency.
