Description

Technical Field

[0001] The invention belongs to the technical field of glass mold processing, and in particular relates to a hydraulic clamp for glass mold processing. Background Art

[0002] Glassware is an indispensable tool in people's daily life. It can not only be used as a carrier, but also as a decoration. Glassware is often made by shaping and cooling glass molds. Glass molds are generally composed of two half molds that cooperate with each other. One side of the half mold is processed into half of the outline of the glassware through a machining center. Fixtures are indispensable equipment for processing glass molds. Fixtures usually include manual fixtures and automatic fixtures. With the continuous upgrading of processing automation, automatic fixtures are gradually becoming popular. They are mainly used in processes with high precision requirements such as milling and assembly after welding of glass molds. Some of the current automatic clamps use a structure in which a motor drives a screw to clamp the claws, some use a structure in which a cylinder pushes the claws to rotate and press the mold from above, and some use a structure in which a cylinder pushes a slide block and pushes the claws to clamp through an inclined surface. Although all of these can automatically clamp and fix the mold, their structures are relatively complex and not easy to adjust, and they cannot be applied to molds of different specifications. Some of the claws will block the processing surface, thereby obstructing the tool. In addition, a large amount of iron filings will be generated during the mold processing process, and the iron filings are easy to leak into the slide and cylinder assembly, which will hinder sliding at the least and cause cylinder failure at the worst.

[0003] In the existing technology, such as the "a clamp device for glass mold processing" provided by the Chinese invention patent application publication number CN102380777A, it includes a base, with guide rails on both sides, a vise fixed frame sliding seat between the guide rails, and a pair of guide rails and vise moving cavities formed on the vise fixed frame sliding seat; the first and second vise fixed frames, the first and second working cylinders are fixed at the two ends of the first and second vise fixed frames, the first and second vise fixed seats are fixed in the middle, and the first and second vise are fixed on the first and second vise fixed seats; the first and second mold horizontal adjustment mechanisms are respectively arranged on the first and second vise fixed frames; the vise drive mechanism is arranged on the base; a pair of horizontal adjustment mechanisms, one of which is arranged on one of the pair of guide rails, and the other horizontal adjustment mechanism is arranged on the other guide rail. This technical solution adopts the structure described above that the cylinder body pushes the clamping claw to rotate and press the mold from the top. The clamp is not fully automatic and requires manual cooperation to complete the clamping work, and there is a problem that the clamping claw blocks the processing surface.

[0004] Another example is the "a fixture structure for processing the mating surface of a glass mold blank" disclosed in the Chinese invention patent application publication number CN103252670A, which includes a base, a base platform and a base vacated cavity are formed on it, a cylinder clearance hole is provided at the center position of the base platform, a sliding guide seat is fixed at the position corresponding to the cylinder clearance hole, the sliding guide seat forms a sliding guide seat cavity, and the first and second supporting modules are fixed on the base platform; the cylinder is fixed in the base vacated cavity; the first and second half mold limiting adjustment mechanisms are arranged at both ends of the base platform; the two-way clamping mechanism is slidably matched with the sliding guide seat and connected to the cylinder column of the cylinder, the first supporting module is located between the sliding guide seat and the first half mold limiting adjustment mechanism, and the second supporting module is located between the sliding guide seat and the second half mold limiting adjustment mechanism. This technical solution adopts the structure described above that the cylinder body pushes the slider and pushes the clamping claw to clamp through the inclined surface, which has the problems of a large number of parts, a complex structure and inconvenient adjustment. In addition, due to the limitation of the driving structure, its cylinder body can only be arranged below the fixture, which makes the overall height of the fixture high, so it is not suitable for small processing centers.

[0005] In view of the above situation, it is necessary to design a hydraulic clamp for glass mold processing with compact structure and easy adjustment, which can prevent the jaws from blocking the processing surface and avoid the impact of iron filings on the fixture.
