Description

Injection molding tool fixing frame and reinforcing structure Technical Field The utility model belongs to the technical field of injection molding cutter fixing frames, and relates to an injection molding cutter fixing frame and a reinforcing structure. Background The existing injection molding tool fixing frame has systematic short plates in the aspect of stable and fixed effects of tools, and is mainly characterized by insufficient dynamic response adaptability and multi-working-condition adaptability of a mechanical structure. The primary defect is that the high-frequency vibration suppression capability is weakened, the contact interface of the sliding seat and the sliding rail is in rigid connection depending on the pretightening force of the bolt, the pretightening force attenuation caused by the impact of an assembly gap and a long-term load can cause nonlinear degradation of contact rigidity, the radial slight vibration of a cutter is easy to be caused under the periodical load of injection molding, the position tolerance precision of a machined surface is directly influenced, the traditional solution relies on low-thermal expansion alloy or an additional heat dissipation structure, but the former greatly improves the material cost and cannot meet the requirement of quick replacement of the cutter, and the latter limits the layout density of the cutter due to the fact that the heat dissipation fins occupy the assembly space, so that an injection molding cutter fixing frame and an enhancement structure are needed to solve the problems. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide an injection molding cutter fixing frame and an enhancement structure, which solve the problems in the background art.
