Solution Overview
Problem
Conventional forged product forming machines are mechanically complex, occupy large space, and have reduced mold service life due to increased temperatures from repeated impacts, necessitating additional cooling devices that further increase space requirements and complicate maintenance.
Innovation Solution
A mold moving device comprising a base unit, transmission mechanism, guiding member, mold seat, and pressing molds, where the guiding member with serpentine guiding grooves drives the mold seat and pressing molds to rotate in precise increments, reducing mechanical complexity and allowing for efficient cooling and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional gripping devices and linkage structures are used for transferring blanks between molds, then accurate and quick gripping motion can be achieved, but mechanical complexity increases and maintenance becomes troublesome and expensive
Solution Approach 1:
The patent removes the complex gripping devices and linkage structures from the system. Instead of using mechanical grippers with complex linkages to transfer blanks, the invention directly feeds blanks into the molds using a simplified feeding mechanism, eliminating the need for complex gripping and transfer linkages entirely.
Solution Approach 2:
Instead of using gripping devices to actively grasp and transfer blanks, the invention inverts the approach by having blanks passively fed directly into the molds through a simplified feeding mechanism, reversing the traditional active gripping approach.
2Productivity
If stamping press device and molds are densely arranged to improve space utilization, then manufacturing efficiency increases, but temperatures of molds increase and service life decreases
Solution Approach 1:
The patent removes the stamping press device from the system, replacing it with a simplified direct-forming mechanism. This elimination of the high-impact stamping press reduces the thermal load and mechanical stress on the molds, allowing for better heat dissipation and extended mold service life while maintaining manufacturing efficiency.
3Ease of operation
If reserve spaces are provided above molds for mounting gripping devices, then gripping function is achieved, but molds cannot be stacked in height direction to reduce area occupied
Solution Approach 1:
The patent eliminates the need for reserve spaces above molds by removing the gripping devices entirely. Blanks are fed directly into the molds from the side or top without requiring vertical clearance for gripping mechanisms, allowing molds to be stacked in the height direction to minimize the horizontal area occupied by the manufacturing system.

AI summary
A mold moving device for a forged product forming machine includes a base unit, a transmission mechanism, a guiding member, a mold seat, and a plurality of pressing molds. The guiding member is driven by the transmission mechanism to rotate, and has an outer peripheral surface formed with a plurality of guiding grooves extending in a serpentine manner. The mold seat includes a rotary shaft, a rotating member, and a carrying member on which the pressing molds are mounted. The rotating member is connected to the rotary shaft, and includes a disk body portion and a plurality of projecting rods protruding toward the guiding member. When the guiding member rotates, the guiding grooves respectively engage selected ones of the projecting rods in a manner where the selected ones of the projecting rods respectively slide along the guiding grooves, thereby driving the disk body portion to rotate.
