Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a tooling auxiliary fixture structure for a mold. Background Art

[0002] A mold is a tool that uses a specific shape to form a blank into a product with a certain shape and size under the action of an external force. Molds are extremely widely used in forging, stamping, powder metallurgy pressing, pressure casting, and compression and injection molding of engineering plastics, rubber, ceramics and other products. The mold is generally divided into two parts, which can be divided into a movable mold and a fixed mold according to the state of motion; and divided into a concave mold and a convex mold according to the shape. There are many types of molds, including steel molds, iron molds, tin molds, wooden molds, gypsum molds, mud molds, etc. Among them, the steel mold is the most widely used, and it is known as the "mother of industry".

By setting the clamping device, the hydraulic cylinder is used to push two gears to perform opposite movements, thereby prompting the movable sleeve to drive two clamping claws to position and clamp the two sides of the mold to be processed, and the clamping process is completed in one step without multiple adjustments, thereby achieving the advantage of convenient positioning and solving the problem of overly complicated positioning steps. Moreover, the entire positioning process is mechanized, thereby avoiding the need for manual tightening, reducing the labor intensity of workers and improving work efficiency.

[0004] The above scheme still has the following technical deficiencies: the above scheme is not convenient for clamping processing molds of different shapes; the above scheme uses a contact block of a clamping grip to clamp the processing mold; since the shape of the processing mold is fixed, it can only clamp a certain fixed processing mold; for processing molds of other shapes, other clamping devices are required for clamping; and its scope of application is small. Based on this, a tooling auxiliary fixture structure for molds is proposed. Utility Model Content
