Standard mold set
Mold frames, which support the mold, refer to the assembly and fixation of mold parts in a certain pattern and position on a die-casting machine, enabling the mold to be mounted on the working part of the machine. They consist of the ejection mechanism, guiding mechanism, pre-resetting mechanism, mold foot pads, and base plate.
Mold frames serve as the foundational skeleton for cold stamping molds, used to install and secure the related components. They ensure that various parts are positioned correctly, with firm and stable installation.
Used to form locating installation and fixed connection with stamping equipment to transfer the force and movement of the stamping equipment to the work piece, and complete the normal stamping forming process.
Therefore, the mold frame is also an important part of the cold stamping mold.
Mold
Molds, used in industrial production for injection molding, blow molding, extrusion, die casting, forging, and other processes to obtain the desired products, are various types of molds and tools. In short, molds are tools used for shaping items, consisting of various components. Different molds are made up of different components. They primarily process the shape of items by altering the physical state of the material being shaped. Known as the "industry" of tools. These tools, under external force, transform raw materials into products with specific shapes and dimensions. They are widely used in cutting, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and the forming processes of engineering plastics, rubber, ceramics, and other products. Molds have specific profiles or cavity shapes. The use of profiles with cutting edges allows the raw material to separate along the profile line (cutting). The cavity shape enables the raw material to acquire the corresponding three-dimensional shape. Molds typically consist of two parts: the moving mold and the fixed mold (or the male and female molds), which can be separated or combined. When separated, the finished product is removed; when combined, the raw material is injected into the mold cavity for shaping. Molds are precision tools with complex shapes, capable of withstanding the expansion force of the raw material. They have high requirements for structural strength, rigidity, surface hardness, surface roughness, and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.
Mold bases, also known as mold shells or mold mounts, serve as the foundation of molds, facilitating their installation and providing support, protection, and connection to the key components (mold cores). Since mold shells do not participate in the molding process, their shape does not change with the parts but is only related to the size and structure of the mold base. Therefore, mold shells can be standardized, meaning they have similar shapes with only variations in size and thickness. Precision mold bases, once standardized, are very convenient to machine. Mold shell manufacturers can pre-process various sizes of mold shell components (such as templates and guide pins) and then assemble them into complete mold shells according to customer requirements. Mold shell standards include Longji, Fortuna, Mold Manufacturing, HASCO, and others. Standard mold base machining equipment primarily includes milling machines, grinding machines, and drilling machines. Milling and grinding machines process six surfaces to the specified size. Drilling machines bore holes on the mold base that do not require high precision, such as screw holes and lifting ring holes, and perform tapping. The basic requirement for a standard mold base is to allow for smooth opening and closing. The ease of opening and closing is directly related to the precision of the four guide pin holes. Therefore, it is common to use CNC vertical machining centers for rapid drilling and boring to achieve the required precision.
