Microstructure of injection moulding machine mould clamping mechanism: design and motion simulation

Abstract

With the advent of intelligence technologies, more and more machines and devices are involved in the creation of complex structures. In the intelligent manufacturing industries, mouldings including injection moulding, blow moulding, compression moulding, and others play critical roles in manufacturing highly precise parts required for building intelligent machines (such as computers, cell phones, robots etc.). The performance of the clamping mechanism directly affects the quality of the microstructure of injection products. The design of the injection moulding mould clamping mechanism is based on the microstructure characteristics of the trip of the toggle lever mechanism ratio, speed ratio, and force amplification ratio. These are used to study the main performance parameters, such as analysis, as well as for the establishment of the physical model of the clamping mechanism. The model is based on the microstructure of injection of hyperbolic elbow clamping mechanism kinematics simulation. Simulation results and theoretical calculation contrast analysis show that the maximum dynamic template speed is 215.34 mm/s. The dynamic templates and cross-head speed ratio is 2.15; therefore, the design of the injection moulding mould clamping mechanism for the microstructure provides favourable technical support. The method described here is important to build complicated moulds required to build highly precise parts to build intelligent machineries.

Multi‐objective particle swarm optimisation of complex product change plan considering service performance

“…The impact of a single node on the product service performance is calculated with Equation (5) in Section 1 with the data in the SPI layer. The impact of a change plan on the product service performance is calculated by Equations (6)(7)(8) proposed in Section 2. Based on all the above work, we can get the multi-objective optimisation model.…”

“…More importantly, changing a critical part can propagate and affect other related parts in a product [6,7]. With the development of technology, the internal structure of advanced products and machines is becoming more and more complex [8]. For the complex product design problems (CPD), if the product design change process is not controlled effectively, these changes will have a notable impact on service performance, cost, and product schedule [9,10], even lead to change failure.…”
