Description

Technical Field

[0001] The utility model relates to the technical field of injection mold processing, and more specifically, to a drilling device for injection mold processing that is convenient for multi-directional fastening. Background Technique

[0002] The TNK-special fixture for machining is a special device used for clamping and fixing workpieces for machining. The TNK-special fixture for machining limits the injection mold. A mold is various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting, or forging, smelting, stamping, drilling, etc.

[0003] The existing drilling devices for mold processing cannot fix the mold in multiple directions. When drilling operations are performed on some special-shaped molds, such as circular molds, the mold often deviates. Moreover, the existing drilling devices for mold processing do not have a drill bit stabilizing device. During drilling operations, the drill bit often shakes, resulting in low processing efficiency of the mold.

[0004] Regarding the technical problem of the drill bit shaking existing in the current drilling device, after a large number of searches, a drilling device for injection mold processing that is convenient for multi-directional fastening with the patent number 202320863888.6 was found. It belongs to the technical field of injection mold processing and includes a bottom plate. Both sides of the top of the bottom plate are fixedly connected with vertical plates, and the top of the vertical plates is fixedly connected with a support plate. By starting the motor, the output end of the motor drives the screw to rotate. The screw drives the clamping plate to move inward. The clamping plate drives the clamping rod and the clamping block to move inward. When the rubber block contacts the injection mold, the clamping rod stops moving. Among them, the clamping rod corresponding to the concave position of the injection mold continues to move inward. When the clamping rod stops moving, the elastic band is stretched. Since both the convex and concave positions on the surface of the injection mold are clamped by the clamping rod and the clamping block, the injection mold can be stably reinforced, possessing the advantage of multi-directional fastening. For fixing an injection mold with an irregular shape, the surface of the fixing part can fit well with the surface of the injection mold, improving the fixing effect of the injection mold. However, the technical solution provided by this patent has the following problems:

[0005] When using this device, the mold is fixed at the upper end of the bottom plate. The drilling equipment cannot change according to the position of the mold. It is necessary to adjust the position of the mold, and it is rather troublesome to adjust the mold. Therefore, the device is not flexible enough during use;

[0006] The utility model can improve the flexibility of the device. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the technical problems proposed in the above background technique and provide a drilling device for injection mold processing that is convenient for multi-directional fastening.

[0017] Further preferred solution: A spring is fixedly installed inside the small rod, and the other end of the spring is fixed on the inner wall of the sleeve rod.

[0018] Beneficial effects:

[0019] 1. By setting a slider and using a chute to limit the position of the slider, the slider moves more stably. When the first limiting plate moves, the rotating screw drives the slider to move, thereby driving the first limiting plate to move inwards. At the same time, the limiting block is embedded inside the limiting groove to further limit the position of the first limiting plate, making it not prone to position deviation and enabling the first limiting plate to move more stably, thus effectively improving the stability of the device.

[0020] 2. By setting a positioning rod, when the positioning rod contacts the surface of the mold, the small rod contracts through the spring. After the positioning rod moves to a suitable position, the clamping block of the small rod is embedded inside the corresponding card slot for limiting, further improving the stability of the small rod and making the mold more stable when fixed. The positioning rod can change according to the uneven surface of the mold, thereby fixing the mold. The anti-sliding block enhances the friction of the small rod, making the mold more stable when fixed and further improving the stability of the device.

[0021] 3. By setting a connecting rod, when the drilling equipment needs to move, the servo motor is started. The servo motor drives the sliding rod to rotate, thereby driving the lower rod to move inside the rectangular groove. At the same time, the upper rod is synchronously limited inside the through groove, and the telescopic rod is used to limit the upper rod simultaneously, making the upper rod move more stably, further effectively improving the flexibility of the drilling equipment and enabling the drilling equipment to change according to the position change of the mold during use.

[0022] 4. In summary, for this drilling device for plastic injection mold processing that is convenient for multi-directional fastening, by setting structures such as connecting rods and positioning rods, the purpose of limiting the mold and adjusting the drilling equipment is achieved. The positioning rod uses the cooperation of the small rod and the sleeve rod to contract, enabling the anti-sliding block to contact the uneven surface, thereby limiting the mold and making the mold more stable during processing. The servo motor is started, and the servo motor drives the connecting rod to rotate, further effectively improving the flexibility of the drilling equipment and enabling the drilling equipment to change according to the position change of the mold during use, making the device more flexible during use.
