Abstract
Typically, the motion of the output link of the mode clamping mechanism has reciprocating linear motion, but the motion of the input link can be reciprocating rocking motion or reciprocating linear motion. In addition, the mold clamping mechanism must have a dead-position configuration for the mold at the closed position. This article focuses on the kinematic design of a mold clamping mechanism having an input link with reciprocating linear motion and having dead-position configuration at closed positions. First, four design concepts of mold clamping mechanisms are proposed based on the mechanism creative design methodology. Then, one of the design concepts is chosen as the design example to illustrate the kinematic design of the mode clamping mechanism with minimal maximum acceleration. According to the design requirements, the best design of the mode clamping mechanism of this article is better than the existing patent by reducing 43.5% acceleration and 18.6% driving force.

Summary
The usage of plastic products is becoming more and more extensive, how to increase the production and quality of plastic products has become a major research topic for engineering. The kinematic behavior of the injection molding machine will be required stricter than ever. In order to improve the stability of the production of plastic products, the vibration and noise during the production process must be reduced, and the life of machine must be extended. The kinematics of mold clamping mechanism must be analyzed first. Good kinematic characteristics of the mold clamping mechanism are the goal pursued manufacturing plastic products. The injection molding machine includes forming section and injection sections. This article focuses on the design of mode clamping mechanism in forming section
