Description

Technical Field

[0001] The utility model relates to the technical field of mold base manufacturing, in particular to a mold base device for quickly replacing a mold core. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the formed material. It is a tool that makes the blank become a part with a specific shape and size under the action of external force. The mould generally consists of a movable mould and a fixed mould (or a punch and a die). The two parts can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mould cavity for forming. The mould is a precision tool with a complex shape. It bears the expansion force of the blank and has high requirements on structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mould production is one of the important indicators of the level of mechanical manufacturing.

[0003] A mold base structure capable of quickly replacing a mold core is disclosed in the Chinese utility model patent application disclosure specification CN217531679U, which includes a base. The utility model provides a limit plate and a compression spring in the compression spring cavity of the mold base, a pull line is connected to the center of the side of the limit plate, and a clamp is connected to the other side of the limit plate, a slide groove is provided at the center of the outer side of the mold base, and a slider connected to the pull line is slidably connected in the slide groove, and fixed clamp grooves are provided on the four sides of the mold core. When replacing the mold core, the clamp is pulled into the compression spring cavity by pulling the slider to release the fixation of the mold core, and the mold core can be disassembled, which is convenient and fast. By providing a fastening mechanism in the four side walls of the mold base, the threaded tube can be driven to rotate by the rotating handle of the fastening mechanism, so that the threaded column moves to push the fastening plate to press the mold core, further improving the fastening performance.

[0004] However, the device lacks the function of facilitating accurate docking of the mold core. When in use, the upper mold base and the lower mold base are not accurately docked, resulting in the inability to accurately inject the mold core, which wastes costs and makes it difficult to clean the inside of the mold core. Not only that, the device lacks the function of saving manpower to carry the upper mold base for quick replacement of the mold core. When in use, the upper mold base is easily dropped when the manual plate is moved, which makes the upper mold base and the upper mold core easily damaged, reducing their service life, thereby increasing costs.
