Description

Technical Field

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

[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. They are often referred to as the "mother of industry." Composed of multiple parts, molds primarily achieve the shaping of objects by altering the physical state of the material being molded. A mold generally consists of two parts: a moving mold and a fixed mold. These parts can be separated or joined; when separated, the workpiece is removed; when joined, the blank is injected into the mold cavity to form the shape. Molds are diverse, categorized by processing object and process into molds for metals and molds for non-metals and powder metallurgy; and by the material being molded, into hardware molds, plastic molds, etc. Molds are widely used in various industries such as automotive, electronics, home appliances, and medical devices, and are a key factor in ensuring product quality, improving production efficiency, and reducing costs.

[0003] Some traditional clamping mechanisms use fixed-structure fixtures that cannot be flexibly adjusted according to the size of the workpiece. This means that when processing workpieces of different sizes, it may be necessary to change clamping mechanisms of different specifications, increasing equipment costs and production preparation time, and reducing production efficiency. To address this technical problem, this application proposes a clamping device for mold processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping device for mold processing. By adjusting the gears, the transmission rod is driven to rotate the first bevel gear. The rotation of the first bevel gear meshes with the second bevel gear, which in turn drives the second bevel gear to rotate. The second bevel gear drives the threaded rod to rotate, causing the connecting slider to slide. The distance between the two clamping blocks is adjusted to clamp the mold. This eliminates the need to replace clamping mechanisms of different specifications, thus improving production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A clamping device for mold processing includes a slide plate with a rotating groove on its top. Four connecting columns are slidably connected to the inner wall of the rotating groove. An adjusting gear is rotatably connected to the top of each connecting column. The outer wall of the adjusting gear is connected to the outer and inner sides of the inner wall of the rotating groove via a rotating assembly to rotate the adjusting gear. A limiting slider is rotatably connected to the top of the adjusting gear. The outer wall of the limiting slider is slidably connected to the inner wall of the rotating groove. Two grooves are formed on the top of the limiting slider. Connecting sliders are slidably connected to the inner walls of the grooves. The inner walls of the two connecting sliders are connected to the top of the adjusting gear via an adjusting assembly to adjust the distance between the two connecting sliders. A clamping block is fixedly connected to the top of the connecting slider. A support frame is fixedly connected to the left side of the slide plate, and a processing device is provided at the bottom of the support frame.

[0007] Furthermore, the rotating assembly includes a second tooth set fixedly connected to the inner side of the inner wall of the rotating groove, the outer wall of the second tooth set meshing with the outer wall of the adjusting gear, and a first tooth set fixedly connected to the outer side of the inner wall of the rotating groove, the outer wall of the first tooth set meshing with the outer wall of the adjusting gear.

[0008] Furthermore, a servo motor is fixedly connected to the inner wall of the slide, and a turntable is rotatably connected to the bottom of the four connecting columns. The drive end of the servo motor is fixedly connected to the top of the turntable.

[0009] Furthermore, the adjusting assembly includes a threaded rod rotatably connected to the inner walls of the two slides, the outer wall of the threaded rod being threadedly connected to the inner wall of the connecting slider, and a second bevel gear being fixedly connected to the outer wall of the threaded rod.

[0010] Furthermore, a transmission rod is fixedly connected to the top of the adjusting gear, and a first bevel gear is fixedly connected to the top of the transmission rod.

[0011] Furthermore, the outer wall of the first bevel gear meshes with the outer wall of the second bevel gear.

[0012] Furthermore, a limiting rod is fixedly connected to the top of the limiting slider, and anti-slip stripes are provided on the adjacent sides of the two clamping blocks.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the first bevel gear is rotated by adjusting the gear and driving the transmission rod. The rotation of the first bevel gear meshes with the second bevel gear, causing the second bevel gear to rotate. The second bevel gear drives the threaded rod to rotate, causing the connecting slider to slide. The distance between the two clamping blocks is adjusted to clamp the mold. There is no need to change the clamping mechanism of different specifications, which speeds up the production efficiency.

[0015] In this invention, a servo motor drives the connecting column to rotate. During rotation, the connecting column passes through the second gear set, causing the adjusting gear to rotate and adjust the distance between the two clamping blocks to clamp the mold. The mold slides to the processing equipment for processing. After processing, the servo motor drives the mold to rotate to the first gear set, causing the adjusting gear to reverse and separate the two clamping blocks, releasing the mold and removing it. The unprocessed mold is then fitted with an upper limit rod. Mold processing and mold collection are performed simultaneously, thereby accelerating mold processing efficiency.
