Problems solved by technology
Its whole manufacturing process is loaded down with trivial details, time-consuming and laborious, inefficiency
Moreover, in the trimming process, repositioning is required, and it is difficult to ensure the accuracy, which will affect the appearance quality of the product; especially for large molds (length and width greater than 1.5 meters) and the sheet material is greater than or equal to 2.0mm, it is even more difficult to achieve the ideal Effect, in addition, two sets of molds need to be prepared, and the cost and operating cost are high

The invention discloses a method for forming a die before trimming and also discloses a die for implementing the method for forming the die before trimming. The die comprises a forming block, a trimming punch and a driving mechanism. The method for forming a die before trimming has the advantages of being simple in process, low in cost and easy to achieve and being capable of achieving the forming before trimming purpose in one die. An upper die is utilized to drive the forming block to be pressed into a forming chamber to enable a sheet to form into the required shape to produce a semi-finished product to achieve the forming purpose and then the driving mechanism is utilized to drive the trimming punch to extend out of an extensible through hole to achieve the purpose of trimming the semi-finished product. Accordingly, the die has the advantages of being skillful and reasonable in structural design, rapid and continuous in integral production process and high in reliability; being good in stability and high in forming accuracy and effectively guaranteeing the product quality due to the fact that the processes of forming and trimming are achieved in the same die; being simple in integral structure, easy to achieve and low in cost.
Description
technical field [0001] The invention relates to mold technology, in particular to a method for forming a mold first and trimming edges and the mold. Background technique [0002] Metal molds are used in industrial production to use various presses and special tools installed on the presses to make metal materials into parts or products of the required shape through pressure. Such special tools are collectively referred to as hardware molds. [0003] All kinds of tools and products we use in our daily production and life, ranging from the base of the machine tool, the shell of the metal mold body, to the small screw, button and the shell of various household appliances, are all closely related to the mold. relation. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearance, specifications and uses of various products, molds are di...
