Description
Technical Field
The invention belongs to the technical field of tool fixtures, and particularly relates to a glass mold fixture structure for a numerical control machining center.
Background
As is known in the art, the aforementioned tooling fixture plays an important role in the production of industrial products, and the processing of glass mold products is no exception. The work fixture refers to a special device or tool for clamping or positioning a workpiece in a machining process so as to meet certain technological requirements. The tooling fixture generally needs to meet the requirements of no interference phenomenon in product production and part processing, accurate and reliable positioning, simple structure, convenient operation, safety and the like. However, because the tooling fixture has the special characteristic for manufacturing a certain product, the degree of generalization is extremely low or even none. In view of the foregoing, the tooling fixture is typically designed and machined by itself or by a entrusted machining unit instead of being machined by the manufacturer that produces the product, in conjunction with the characteristics of the product and the associated requirements of the machining equipment.
The published chinese patent documents do not contain any technical information on a tool holder for processing a glass mold and a glass mold accessory, and examples thereof include CN101659015B (a tool holder for processing a glass mold), CN101891373B (a tool holder for a glass vessel), CN101891372B (a tool holder for a glass vessel), CN101898311B (a holder structure for milling a positioning reference surface on a glass mold blank), CN102380777B (a holder device for processing a glass mold), CN102443859B (a holder device for processing a glass mold), CN102350650B (a holder for processing a glass mold), CN102350651B (a holder device for processing a glass mold with an improved structure), CN102689187A (a turntable-type tool holder for processing a glass mold), CN102848039A (a holder structure for processing a glass mold punch cooling groove disposed on an electric discharge machine), CN102837213A (a holder structure for processing a glass mold), CN102848246A (a tool holder for processing a glass mold), CN102848245A (fixture structure for glass mold processing), CN103056695A (fixture structure for glass mold cavity and joint surface processing), CN103084771A (fixture structure for open-close type forming mold hinge welding), CN103273350B (fixture structure for parallel surface milling of glass mold), CN203031352U (external processing fixture of double-drop glass mold), CN205834843U (fixture for machining glass mold), CN206253847U (fixture for glass mold cavity spray welding), CN107900594A (fixture structure for glass mold cavity spray welding), and CN110561150A (fixture structure for processing V-shaped groove at end of matching surface of glass mold).

For example, if a numerical control center takes forty minutes to complete the above-mentioned machining process and an operator takes ten minutes to complete the clamping of a pair of glass molds (remove the machined mold half 20 and place the next mold half 20 to be machined into the mold half holder 76 and clamp the mold half), then one operator can perform four numerical control machining centers.
After the machining is completed in the nc machining center, the operator operates the opposite operation, for example, the half-mold holder opening and closing screw 75 is operated in the opposite direction to the above operation, the bottle half-mold end face tightening bolt 34 is released, the pair of front platen bottle half-mold pressing claws 3212 and the pair of rear platen bottle half-mold pressing claws 4212 are rotated by an angle, that is, by avoiding the obstruction to the upper surfaces of the front and rear ends of the half mold 20, the machined half mold 20 is removed from the half-mold holder 76, and the next half mold 20 to be machined in the nc machining center is clamped.
In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
