摘要：

为了提高设备整体的运行效率以保证产品的多样化，产品在生产中的换模流程必须提速。通过对Y企业换模流程进行分析与研究，总结换模时间所存在的浪费现象，进一步缩短换模时间并重新安排换模流程；将原有的螺钉锁紧换模机构更改为模具快换机构，并由1个独立的电气系统进行控制；除此之外，还在系统控制中加入了安全继电器，保证了设备及最重要的人身安全，防止恶性事故发生或尽可能减少事故发生后的损失。改造后，整个模具的更换流程得到了改善，换模时间也减少了约63%，较短的换模时间使生产更加柔性化、均衡化，并且提高了企业对市场需求的响应能力，降低了运作成本，提高了企业的竞争力。

In order to improve the overall operating efficiency of equipment to ensure the diversification of products, the mold change process of products in the production must be accelerated. Therefore, through the analysis and research on the mold change process of Y enterprise, the waste of mold change time was summarized to further shorten the mold change time and rearrange the mold change process. Then, the original screw-locking mold change mechanism was changed into rapid mold change mechanism, which was controlled by an independent electrical system. In addition, the safety relays were added to the system control to ensure the equipment safety and the most important personal safety, and prevent the occurrence of malignant accidents or minimize the loss after accidents. Furthermore, after the transformation, the whole mold change process was improved, and the mold change time was reduced by about 63%. Thus, the shorter mold change time makes the production more flexible and balanced, and improves the ability of enterprises to respond to market demand, reduces the operating cost, so that the enterprise is more competitive.
