AI Technical Summary

Technical Problem

Traditional mold-locking mechanisms rely on manual operation, which is labor-intensive, has a low degree of automation, and the upper and lower molds are not securely locked, making them prone to loosening and affecting mold positioning accuracy and product quality.

Method used

Design a mold frame with a mold-locking mechanism. The mold-locking structure is automatically locked by working together with a buffer component, a linkage mechanism and a mold-locking structure. The mold-locking structure is triggered synchronously during the mold closing stroke by the linkage mechanism, without the need for manual intervention. Combined with unidirectional transmission and buffer design, it ensures that the mold does not loosen during high-pressure molding.

Benefits of technology

It enables automatic locking of the mold during high-pressure molding, preventing overflow and flash at the mold parting surface, improving mold positioning accuracy and locking reliability, ensuring smooth mold opening and closing, extending service life, and making it suitable for continuous automated production.

Abstract

The present application relates to the technical field of mould, and discloses a mould frame with a mould locking mechanism, which comprises a mould frame body, an upper mould, a lower mould, a power component, a buffer component and a mould locking box.The lower mould is installed on the mould frame body, the upper mould is slidably connected with the mould frame body, and the power component is connected with the upper mould through the buffer component.Each mould locking box is arranged on the two sides of the mould frame body, and a mould locking structure is arranged between each mould locking box and the upper mould and the lower mould.The mould locking structure is connected with the buffer component through a linkage mechanism.During the mould closing process driven by the power component, the linkage mechanism drives the mould locking structure to lock the upper mould and the lower mould.The mould locking structure comprises a mould locking plate and a locking block, and the upper mould and the lower mould are provided with a locking groove, and the locking block can be clamped in the locking groove.The linkage mechanism comprises a driving plate and a power unit, and a one-way transmission mechanism is further arranged to realize the mould locking and unlocking functions.
