Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, in particular to a mold clamping piece with a protective function. Background Art

[0002] In modern industrial production, molds, as essential manufacturing tools, are widely used in various fields. Injection molding, in particular, plays an irreplaceable role. Mold precision and quality directly impact product quality and production efficiency. Mold clamps, key components that secure the mold, have a crucial impact on mold performance.

[0003] The traditional mold clamping method usually involves tightening bolts to fix the movable mold base plate and the fixed mold base plate of the mold to the injection molding machine. However, when fixing the mold in this way, the pressure plate usually only contacts the movable mold base plate and the fixed mold base plate at a certain point. This will cause serious wear to the fixed position during long-term fixation of the mold, thereby affecting the appearance of the mold. In addition, this single-position contact fixation method may also cause uneven force on the mold. During the injection molding process, the mold will be subjected to forces from various aspects such as injection pressure. If the pressure plate is only fixed at a certain point, the force on the mold will be concentrated at the fixed point, which can easily cause deformation of the mold, thereby affecting the precision and service life of the mold.
