Blow mold maintenance_ Deman Machinery

Blow mold maintenance is one of the daily things to do in the process of mold use.

In the use of blow molds, it is inevitable to produce some wear. When it comes to the maintenance of blow molds, trained technical personnel are required to operate them. They are familiar with the technical standards of blow molds in the operation process.

Today, we will share the maintenance of blow mold precautions.

1. The sliding parts, such as core-pulling mechanism and guiding device, should be thoroughly cleaned and carefully checked. Relubricate with high temperature grease before assembly.

2. If there is hydraulic core-pulling, the hydraulic part should be maintained and maintained at the same time as the blow mold. The maintenance of the hydraulic part needs to pay special attention to cleaning to prevent pollution, otherwise it will pollute the hydraulic system of the whole die casting machine.

3. When the mold fails or is damaged in the production engineering, the repair plan should be determined according to the specific situation.

4. to complete the maintenance of the blow mold, to do rust prevention treatment on the forming surface, parting surface, installation surface, close, set the mold, according to the installation direction of the mold on the machine, placed on the pad. The mold attachment is placed with the blow mold.

5. to thoroughly clean the residual metal chips and scaling everywhere blow mold.

6. Refer to the blow molding products sent for repair together with the blow molding mold, carefully check the problems existing in the mold, which can be checked from the following aspects:

There is no strain, mold sticking, small core bending or broken, movable core insertion positioning is not correct, there is no broken push rod or push rod length change, there is no insert positioning is not correct, there is no fastening bolt loose, etc. Determine repair or replacement according to the damage.

7. The cavity collapse, crack and falling block that lead to slight strain of castings can be repaired by local welding. Welding repair should be strictly operated by welding repair process, otherwise the life of a lot of blow molds will be lost. The above faults of smaller molded parts will be more serious or even die damage.

In order to save costs, many manufacturers do not have a separate mold manufacturing department. There may be only mold maintenance department, but generally only simple mold maintenance and daily maintenance work. The design, manufacture and modification of molds are all undertaken by other cooperative factories. So the quality of the mold can not be guaranteed. Molds are more likely to have problems. Once mold problems occur, the maintenance department cannot repair by itself, but can only repair through cooperative manufacturers, which will bring more losses.

We have our own technical team. Moreover, our blow moulds are independently designed and produced by experienced engineers. The quality and performance of blow moulds are reliable. In the case of problems, our engineers can quickly and accurately find the problem and provide repair services. Reduce labor cost, production cost, improve the efficiency of the production department.

And to that, one more thing. The role of mold in blow molding machine is also crucial. In addition to the performance of blow molding machine itself, the performance of blow molding mold also directly affects the quality of blow molding products. Therefore, the maintenance of blow molds should consider all aspects comprehensively and take a high maintenance method.

Blow mold maintenance precautions to share here.

I hope it helps.
