Embodiment Construction

[0017] The injection molding machine is mainly composed of an injection device and a hydraulic transmission system. Among them, the injection device is composed of a plasticizing device, a hopper, a metering device, a screw drive device, and an injection cylinder. The hydraulic transmission system is mainly composed of hydraulic pumps, hydraulic valves, flow valves, pressure valves and other components.

[0018] Such as figure 2 As shown, through the investigation of the operation of the injection molding machine in actual production, it is found that the hydraulic system, injection mechanism and mold temperature control process of the injection molding machine currently have the following problems: (1) Due to the needs of the molding process and different production processes, the injection molding machine is The flow and pressure required in the working process are often different and often change. Generally, different combinations of quantitative pumps (dual pump oil supp...

Abstract

The invention provides a TRIZ (theory of inventive problem solving)-based injection mechanism for an injection molding machine. An original hydraulically powered injection system is replaced with an injection mode of directly pushing molten fluid by high-pressure air; a high-light injection technology and infrared radiation are adopted for heating. Experiments prove that with application of the TRIZ-based injection mechanism for the injection molding machine, production efficiency of a system and surface and inner quality of a product are improved qualitatively; bad characteristics of poor reliability, system complexity, environmental pollution, noise, unstable working performance and the like of the system are improved and enhanced fundamentally.

Description

technical field [0001] The invention relates to an injection mechanism of an injection molding machine based on TRIZ. Background technique [0002] The conceptual design methods and tools centered on TRIZ can effectively solve key problems in product development and design, carry out product innovation design, improve product quality, reduce costs, and reduce market response time. TRIZ is a high-level product innovation design theory based on logical thinking, among which conflict matrix and invention principle are the most mature tools in TRIZ, which can help designers recombine, modify, associate, reason and abstract, etc. , form innovative ideas and design concepts to complete product development and innovation. Most of the injection molding machines currently on the market have problems such as high energy consumption, low efficiency, pollution, low control precision and product precision, slow heating of mold temperature and difficult control, insufficient injection sp...
