Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a fixing device for mold processing that facilitates center positioning. Background Technology

[0002] A mold is a tool used to shape objects into specific forms. It consists of various parts and is widely used in industrial production, enabling mass production and high-precision manufacturing. Centering is required during mold processing because accurate centering ensures that the installation positions of each mold component are precise, and that key parts such as the upper and lower molds or cavities and cores are strictly aligned. This avoids workpiece size errors, shape defects, or accelerated mold wear caused by positional deviations, thereby ensuring processing accuracy and product quality, improving production efficiency, and extending the mold's service life.

[0003] Chinese Patent Publication No. CN222095876U discloses a fixing device for mold processing, including a base. A rectangular groove is formed downwards at the upper end of the base, and a guide rail is provided at the bottom of the rectangular groove. Clamping devices are symmetrically installed on both sides of the rectangular groove. The clamping devices are equipped with positive and negative threaded screws, causing the two clamping devices to move towards each other to complete the clamping. The clamping device includes an L-shaped plate and a clamping block. The clamping block is installed above the L-shaped plate, with an arc-shaped clamping part on the upper side and a flat clamping part on the lower side. When the clamping block is in the low position, the upper surface of the flat clamping part is flush with the upper surface of the base, facilitating the fixing of circular molds by the arc-shaped clamping part on the upper side. This utility model has strong versatility, can fix both circular and square molds, meets the fixing needs of molds of different shapes, and reduces equipment costs.

[0004] While existing devices can meet the fixing requirements of molds of different shapes, they cannot center the mold placement during the fixing process, which can cause the mold placement to shift, thus causing inconvenience to subsequent processing. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Reference Figure 1-6 A mold processing fixing device for easy center positioning includes a mounting base 1. An electric push rod 2 is fixedly mounted on the right side of the mounting base 1. A rack 3 is fixedly connected to the telescopic end of the electric push rod 2. A fixing assembly is provided on the top and inside of the mounting base 1. The fixing assembly includes a limiting slide groove 301, a transmission slide groove 302, a limiting slider 303, a fixing bar 304, a toggle post 305, a transmission disc 306, an arc-shaped transmission groove 307, a gear 308, and a protective pad 309. The limiting slide groove 301 is arranged in a ring array on the top inner wall of the mounting base 1. A movable groove 302 is formed on the bottom inner wall of the limiting groove 301. A limiting slider 303 is slidably connected inside the limiting groove 301. A fixing strip 304 is fixedly installed on the top of the limiting slider 303. A toggle post 305 is fixedly connected to the bottom of the limiting slider 303. A transmission disc 306 is rotatably connected inside the mounting base 1. Arc-shaped transmission grooves 307 are arranged in a ring array inside the transmission disc 306. A gear 308 is fixedly connected to the bottom of the transmission disc 306. A protective pad 309 is fixedly connected to the side of the fixing strips 304 that are close to each other. The fixing strips 304 are arranged in a ring array on the top of the mounting base 1.

[0028] The fixing strip 304 can fix the mold by clamping the side of the mold. At the same time, the protective pad 309 can not only increase the stability of the contact with the side of the mold, but also improve the safety of the side of the mold and avoid damage to the side of the mold. The fixing component is set up so that by activating the electric push rod 2, the telescopic end of the electric push rod 2 drives the rack 3 to extend. During the extension process, the rack 3 drives the gear 308 and the transmission disk 306 to rotate. During the rotation of the transmission disk 306, the arc-shaped transmission groove 307 inside it can move the actuating column 305, thereby driving the limiting slider 303 to move inside the limiting groove 301 and move closer to the center of the mounting base 1. Since the fixing bar 304 is located on the top of the limiting slider 303, when the limiting slider 303 moves to a certain position, it can drive the fixing bar 304 to be locked on the side of the mold. At the same time, since the limiting sliders 303 distributed in an array on the top of the mounting base 1 move synchronously, the mold can be fixed and the center of the mold can be positioned at the same time. This utility model, through the setting of the fixing components, enables the fixing bars 304 arranged in an array on the top of the mounting base 1 to move synchronously towards the mold under the rotation of the transmission disk 306. This achieves the clamping and fixing of the mold, while also keeping the mold in the center position of the mounting base 1, preventing the mold installation position from shifting, thereby effectively improving the convenience and safety of subsequent mold processing.

[0029] Furthermore, an extension bar 4 is fixedly connected to the top of the limiting slider 303. The extension bar 4 is movably engaged with the limiting groove 301. An extension component is provided inside the extension bar 4. The extension component includes a limiting groove 401 and a helical spring 402. The limiting groove 401 is opened inside the limiting slider 303. The fixing bar 304 is movably engaged with the limiting groove 401. The helical spring 402 is fixedly connected inside the limiting groove 401 and is fixedly connected to the fixing bar 304.

[0030] The extension component is designed so that when the fixing bar 304 clamps and fixes the irregularly rotating mold, the extension bar 4 that first contacts the side of the mold will slide inside the limiting slide groove 401 through the movement of the limiting slider 303, and the elastic force of the helical spring 402 will drive the fixing bar 304 to make close contact with the side of the mold and fit against the side of the mold. The fixing bar 304 on the other side will also eventually contact the side of the mold after the limiting slider 303 moves continuously, thereby clamping and fixing the mold.

[0031] Furthermore, a support pad 5 is fixedly connected to the top of the mounting base 1 and between the limiting slide groove 301. The top of the support pad 5 is provided with bearing balls 6 arranged in a ring array. A storage groove 7 is provided between the bearing balls 6 and between the top of the support pad 5.

[0032] The bearing balls 6 not only support the placed mold, but also facilitate the adjustment of the mold's position during the center positioning and clamping process of the fixing bar 304, effectively improving practicality.

[0033] A lead screw 8 is fixedly connected to the top of the transmission disc 306. A connecting groove 9 is provided on the top of the mounting base 1. A square hole 10 is provided on the lower surface of the connecting groove 9. An expansion hole 11 is provided on the right side of the mounting base 1.

[0034] Furthermore, a support assembly is provided on the outside of the lead screw 8. The support assembly includes a square support rod 801, a threaded hole 802, a support plate 803, and an anti-slip pad 804. The square support rod 801 is movably sleeved on the outside of the lead screw 8.

[0035] A threaded hole 802 is formed inside the square support rod 801, a support plate 803 is fixedly connected to the top of the square support rod 801, and an anti-slip pad 804 is fixedly connected to the top of the support plate 803.

[0036] The square support rod 801 and support plate 803 provide support for the mold, while the anti-slip pad 804 increases friction with the mold, improving the safety and stability of mold placement. With the support assembly in place, the gear 308 drives the transmission disc 306 to rotate, simultaneously rotating the lead screw 8. As the lead screw 8 rotates, the threaded hole 802 inside the square support rod 801 connects to the lead screw 8, and the square support rod 801 matches the square hole 10, causing the square support rod 801 to descend. During this descent, the support plate 803 is retracted into the receiving groove 7 and the connecting groove 9, and the mold then rests on the surface of the bearing balls 6. This invention, through the design of the support assembly, makes the mold more stable during placement, preventing wobbling and effectively improving mold safety.

[0037] Furthermore, the limiting slider 303 is movably engaged with the limiting slide groove 301, the actuating column 305 passes through the transmission slide groove 302 and is located inside the arc-shaped transmission groove 307, and the rack 3 is meshed with the gear 308.

[0038] The transmission disc 306 drives the arc-shaped transmission groove 307 to rotate, which can move the actuating column 305.

[0039] The square support rod 801 is adapted to the square hole 10, the connecting groove 9 is adapted to the support plate 803, and the threaded hole 802 is threadedly connected to the lead screw 8.

[0040] The square hole 10 can limit the position of the square support rod 801.

[0041] In summary:

[0042] In use, the operator first places the mold on top of the anti-slip mat 804, and then starts the electric push rod 2, which causes the telescopic end of the electric push rod 2 to drive the rack 3 to extend. During the extension process, the rack 3 can drive the gear 308 and the transmission disk 306 to rotate, and the transmission disk 306 will also drive the lead screw 8 to rotate while rotating.

[0043] When the lead screw 8 rotates, the threaded hole 802 inside the square support rod 801 is threadedly connected to the lead screw 8, and the square support rod 801 is matched with the square hole 10, which can drive the square support rod 801 to descend. During the descent, the square support rod 801 can be stored in the support plate 803 into the storage groove 7 and the connecting groove 9, and then the mold will fall on the surface of the bearing ball 6.

[0044] During rotation, the transmission disc 306 can move the actuating column 305 through its internal arc-shaped transmission groove 307, thereby driving the limiting slider 303 to move inside the limiting groove 301 and move closer to the center of the mounting base 1. Since the fixing bar 304 is located on top of the limiting slider 303, when the limiting slider 303 moves to a certain position, it can drive the fixing bar 304 to lock onto the side of the mold. At the same time, since the limiting sliders 303 arranged in an array on the top of the mounting base 1 move synchronously, the mold located on the bearing ball 6-second surface can be fixed and the center positioning can be achieved.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
