Background

The foregoing glass molds are primarily, but not exclusively, referred to as cast copper alloy dies. The function of the casting head is well known in the casting industry, in particular to add supplementary parts above and/or to the sides of the casting in order to avoid defects in the casting. In the casting mould, the cavity of the casting head is a container for storing liquid metal, the functions are manifold, and the forms, sizes and opening positions of the casting heads with different functions are different, so that the design of the casting head needs to take the characteristics of castings with different products into consideration. In patent documents, not limited to the following examples, technical information related to the glass mold casting head is mentioned to various degrees, such as CN102672113A (method of casting copper alloy die of glass mold from resin sand single box), CN102430700A (method of casting copper alloy bottom mold of glass mold from resin sand single box), CN102828103B (alloy gray cast iron glass mold and preparation method thereof), and CN111334684A (solid-liquid state high toughness high thermal conductivity copper alloy glass mold and preparation method thereof), and so on.

For glass molds of copper alloys, such as dies, which are usually obtained by casting, casting heads are left in the final cast part to ensure the quality of the cast part, as described above, and the casting heads need to be removed before the glass mold is initially machined, otherwise subsequent initial machining processes cannot be performed.

As is known in the art, the aforementioned tooling fixture plays an important role in the production of industrial products, and the term tooling fixture refers to a special equipment or tool used for clamping or positioning a workpiece during a machining process to meet certain process 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.
