Description

Technical Field

[0001] This invention belongs to the field of glass mold processing technology, and specifically relates to a hydraulic clamp for glass mold processing. Background Technology

[0002] Glassware is an indispensable part of people's daily lives, serving not only as a medium but also as a decorative item. Glassware is often made by shaping and cooling glass molds. A glass mold generally consists of two interlocking half-molds. One side of each half-mold is machined using a machining center to create half of the glassware's outline. Tooling fixtures are essential equipment for processing glass molds. Tooling fixtures are typically divided into manual and automatic types. With the continuous upgrading of processing automation, automatic fixtures have gradually become more widespread, mainly used in high-precision processes such as milling and fitting of glass molds after welding. Current automatic clamps employ various structures, including those using a motor-driven screw to clamp the jaws, those using a cylinder to rotate the jaws and press the mold from above, and those using a cylinder to push a slider and then a ramp to clamp the jaws. While all these methods can automatically clamp and fix the mold, they are all relatively complex and difficult to adjust, making them unsuitable for molds of different sizes. Some jaws may also obstruct the machining surface, thus hindering the cutting tool. Furthermore, the machining process generates a large amount of metal shavings, which can easily leak into the slide and cylinder assembly, causing minor issues like obstructing the sliding or even cylinder malfunction.

[0003] In existing technologies, such as the "clamping device for glass mold processing" provided in Chinese invention patent application publication number CN102380777A, a base is provided with guide rails on both sides, and a sliding seat for a clamp fixing frame is provided between the guide rails. A pair of guide rails and a clamp moving cavity are formed on the sliding seat for the clamp fixing frame; first and second clamp fixing frames, with first and second actuating cylinders fixed at both ends of the first and second clamp fixing frames, and first and second clamp fixing seats fixed in the middle of the first and second clamp fixing frames, with first and second clamps fixed on the first and second clamp fixing seats; first and second mold horizontal adjustment mechanisms are respectively provided on the first and second clamp fixing frames; a clamp driving mechanism is provided on the base; and a pair of horizontal adjustment mechanisms, one of which is provided on one of the guide rails and the other is provided on the other guide rail. This technical solution uses the structure described above where the cylinder pushes the chuck to rotate and press the mold from above. This clamp is not fully automatic and requires manual assistance to complete the clamping work, and there is a problem that the chuck obstructs the processing surface.

[0004] For example, the "Jig Structure for Machining the Mating Surface of a Glass Mold Blank" disclosed in Chinese Invention Patent Application Publication No. CN103252670A includes a base, on which a base platform and a base cavity are formed. An actuation cylinder clearance hole is opened at the center of the base platform. A sliding guide seat is fixed at the position corresponding to the actuation cylinder clearance hole, forming a sliding guide seat cavity. First and second support modules are fixed on the base platform. The actuation cylinder is fixed within the base cavity. First and second half-mold limiting adjustment mechanisms are located at both ends of the base platform. A bidirectional mold clamping mechanism slides with the sliding guide seat and connects to the actuation cylinder column of the actuation cylinder. The first support module is located between the sliding guide seat and the first half-mold limiting adjustment mechanism, and the second support module is located between the sliding guide seat and the second half-mold limiting adjustment mechanism. This technical solution uses the aforementioned structure where the cylinder pushes the slider and the inclined plane pushes the chuck for clamping. This has problems such as a large number of parts, complex structure, and inconvenience in adjustment. Moreover, due to the limitations of the drive structure, the cylinder can only be located below the fixture, making the overall height of the fixture relatively high, thus unsuitable for small machining centers.

[0005] In view of the above, it is necessary to design a compact, easily adjustable hydraulic clamping fixture for glass mold processing that can prevent the chucks from obstructing the machining surface and avoid the impact of metal chips on the clamping device. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Summary of the Invention
