The structure and function of the upper and lower die of the standard die frame

The standard die holder has a preforming device, a positioning device and an ejector device. It is generally configured as A panel, A board (front template), B board (back template), C board (square iron), bottom plate, thimble panel, thimble bottom plate, and spare parts such as guide posts and return pins.

The so-called two open mold is that there are two main cavities, can be left and right open mold, can also open mold up and down, the common standard mold frame is two open mold, only in the working case of the upper and lower open mold, generally speaking, the upper and lower open mold is common in the punching machine, pouring machine, hydraulic press Z, and in this case, the upper mold is also called dynamic mold, the lower mold is called static mold, this is because, When the mold is opened, the mechanical mechanism drives the moving mold to rise and complete the opening action, so the upper mold and the lower mold appear.

Above the standard die frame is a typical die frame structure drawing. The right part is called the upper die and the left part is called the lower die. When injection molding, the upper and lower molds are combined first to form the plastic in the upper and lower module molding part. The upper and lower molds are then separated and the finished product is pushed out by the ejector device based on the following molds.

The standard mold is an integral part of the mold. At present, the accuracy requirements of the non-standard mold frame will be determined according to the product demand at different levels, and the mold frame just matches the different needs of various customers to provide suitable supply. In the production of non-standard mold frame manufacturing process, especially in the process of industrial production of mechanical parts, various functional parts must rely on mold frame molding. The basic requirement of a standard mold frame is to smoothly open the mold. The smooth opening of the mold is directly related to the precision of the 4 guide post holes. Therefore, in general, it is necessary to use CNC vertical machining centers for rapid drilling and boring to achieve precision.
