Mold frame
Mold bases, also known as mold shells or mold seats, serve as the foundation for molds, facilitating installation and providing support, protection, and connection to the critical mold components (mold cores). Since mold shells do not participate in the molding process, their shape does not change with the part and is only related to the size and structure of the part. Plastic mold bases can be standardized, meaning the mold shell forms are generally similar, with only variations in size and thickness. Standardization simplifies mold manufacturing, as mold shell manufacturers can pre-process various sizes and specifications of mold shell components (templates, guide pins), and then assemble them into complete mold shells as per customer requirements. Mold shell standards include Longji, Fortuna, and HASCO. Standard mold base processing equipment mainly includes milling machines, grinding machines, and drilling machines. Milling machines and grinding machines process the mold base to achieve a specified size and finish on six surfaces. Drilling machines are used for less precise holes on the mold base, such as screw holes and lifting ring holes, for drilling and tapping. The basic requirement for a standard mold base is that it must allow for smooth mold opening. The ease of mold opening is directly related to the precision of the four guide pin holes. Therefore, it is common to use CNC vertical machining centers for quick drilling followed by boring to achieve the required precision.


Mold
Molds, used in industrial production for injection molding, blow molding, extrusion, die casting, forging, and other processes to obtain desired products through various molds and tools. In short, molds are tools used to create shaped 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 stamping, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and the forming processes of engineering plastics, rubber, ceramics, and other products. Molds have specific profiles or cavity shapes, and the use of edged profiles allows the raw material to separate along the profile line (cutting). The use of cavity shapes enables the raw material to acquire corresponding three-dimensional shapes. 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, withstand the expansion force of the raw material, and have high requirements for structural strength, rigidity, surface hardness, surface roughness, and processing accuracy. The development level of standard mold frame manufacturers is one of the important indicators of the level of mechanical manufacturing.


Molds are supported by mold frames, which involve assembling and securing the various parts of the mold in a specific pattern and position on a die casting machine, allowing the mold to be mounted onto the working section of the machine. A mold frame consists of the ejector mechanism, guide mechanism, pre-reset mechanism, foot pads, and base plate.

Molds are the fundamental framework for cold-forming dies, used to install and secure the related components, ensuring proper positioning and firm, stable assembly.

Used to form locating and fixed connections with stamping equipment, to transfer the force and motion of the stamping equipment to the workpiece, and complete the normal stamping forming process.

So, the mold base is also an essential part of the cold stamping die.
