Mold is known as the "mother of industry" and one of the core technologies of manufacturing industry. At present, most mold enterprises are facing the problem of "people". The problem of "human" has become a pain point in the management of mold enterprises. As an equipment supplier, we carry out development from the aspects of equipment function, processing accuracy and automation, and are committed to providing some less humanized or even unmanned production solutions for the industry, hoping to help the industry solve some pain points. If the mold is well made, effective and timely maintenance should also be carried out for long-term effective utilization:

模具的一级保养装模时的保养（1）装模前，要对模具的上下表面进行清擦，保证模具安装面和压机工作台面不受压伤，及模具在生产中上下安装面的平行度。

First level maintenance of the mold maintenance during mold installation (1) before mold installation, the upper and lower surfaces of the mold shall be cleaned to ensure that the mold installation surface and the working table of the press are not damaged by pressure, and the parallelism of the upper and lower installation surfaces of the mold in production.

（2）模具装好后，将模具打开，将模具各部分清擦干净，特别是导向机构，对于表面件模具，其型面清擦干净，以保证制件的质量。对模具各滑动部分进行润滑，涂润滑脂。模具各部份的检查，特别是件，如：侧销、螺钉、侧护板、冲孔废料道等。

(2) After the mold is installed, open the mold and clean all parts of the mold, especially the guide mechanism. For the surface mold, the mold surface shall be cleaned to ensure the quality of the parts. Lubricate the sliding parts of the die and apply grease. Inspection of all parts of the die, especially safety parts, such as safety side pins, safety screws, side guards, punching waste channels, etc.

生产中的保养（1）生产中，定期对模具的相应部分进行涂油，如：拉延模的压料圈、圆角；修边模的刀口部位；翻边刀块部分等。

Maintenance in production (1) during production, oil the corresponding parts of the die regularly, such as the pressing ring and fillet of the drawing die; Knife edge of trimming die; Flanging cutter block, etc.

（2）定期对修边冲孔模的小孔废料道进行废料的清理。

(2) Regularly clean the small hole waste passage of trimming and punching die.

生产后的保养（1）生产结束后，要对模具进行的检查。

Maintenance after production (1) after production, conduct a comprehensive inspection of the mold.

（2）模具进行的清擦，保证模具的清洁度。

(2) The mold shall be cleaned comprehensively to ensure the cleanliness of the mold.

（3）将模具内的废料清理干净，保证废料盒中无废料。

(3) Clean up the waste in the mold to ensure that there is no waste in the waste box.

（4）将模具的使用状态和使用后的情况如实地反馈到模具传票上。

(4) Feed back the use status and post use situation of the die to the die ticket truthfully.

模具的二级保养此项保养工作由模修人员完成，并根据保养情况作好记录。以下就不同的零件叙述其二保的要求和方法：

Secondary maintenance of mould this maintenance work shall be completed by the mould repair personnel, and records shall be made according to the maintenance situation. The following describes the requirements and methods of secondary warranty for different parts:

拉延模凸模、凹模拉延模的凸、凹模，主要出现的问题是拉毛及型面的压坑。保养时，主要对模具的圆角拉毛部位进行抛光。如果出现压坑，要对模具进行补焊，再进行修顺。

The main problems of male and female dies of drawing die are roughening and indentation on the profile. During maintenance, mainly polish the rounded and roughened parts of the die. If there is a pressure pit, the mold shall be repaired and smoothed.

导向零件（导柱、导套及导板等）模具在工作中会出现拉痕等现象。产生的主要原因有润滑油脏及导向间隙偏等。导向零件产生拉痕，采取用油石推顺后抛光的办法进行。

The die of guide parts (guide post, guide sleeve and guide plate, etc.) will have pull marks during operation. The main causes are dirty lubricating oil and eccentric guide clearance. Pull marks on guide parts shall be eliminated by polishing after being pushed by oilstone.
