Injection mould heating matters needing attention

To make injection mold manufacture process to work fine artifacts, we will to heating the injection mold, not only can improve precision of injection mold height, can improve the quality and precision high, the use of the Thai can injection mold factory is to share: considerations about injection mould heating, main points four link, the forging process, prepare heat treatment, quenching and tempering, annealing. Here are the attention of each link point. One, the forging process. This is the important link in the process of the working parts of the injection mold manufacturing. For high alloy tool steel molds, usually on the material distribution of carbide microstructure such as technical requirements are put forward. In addition, still should strictly control the forging temperature range, formulate correct heating specification, adopt the correct forging force method, and slow cooling after forging or annealing in a timely manner. Second, the preliminary heat treatment. Should inspect the materials of the injection mold parts and requirements of different annealing, normalizing and tempering were used respectively to prepare heat treatment process, to improve the organization, eliminate forging blank tissue defects, improve the fabrication procedure. High carbon alloy steel after appropriate preparatory heat treatment can eliminate mesh secondary cementite or chain carbide, carbide spheroidizing, refinement, to promote the carbide distribution uniformity. Which is beneficial to ensure the quality of quenching, tempering, improve die life. Three, quenching and tempering. This is the key links of the mold heat treatment. If cause overheating during quenching heating, not only can make the workpiece caused large brittleness, and easy to cause deformation and cracking during cooling, seriously affect the die life. Die quenching heating when special attention should be paid to prevent oxidation and decarburization, should strictly control the heat treatment process specification, in conditions allow, can use vacuum heat treatment. Should be timely tempering after quenching, and according to the technical requirements for different tempering process. Fourth, eliminate stress annealing. Injection mold processing parts shall be carried out after eliminating stress annealing treatment, the purpose is to eliminate the internal stress caused by the rough machining, lest produce excessive deformation and crack in the quenching is called. For the high precision requirement of mould, after grinding or machining need through eliminating stress tempering processing, is beneficial to stable mold precision, improve the service life. Heat treatment is the process of injection mould must go through before they go out, but not every injection mold factory can standard execution, and it also should pay attention to technology, mold factory for the industry has established a new standard mould heating, made from each mold has reached the height of the precision.





injection mold processing, the upper and lower mould which must pay attention to safety matters?


plastic products of injection mold is a kind of production tools, also is to increase the complete structure of plastic products and precise size of the tool. You know, when the injection mold processing, upper and lower mould which must pay attention to safety matters? Believe that is a lot of people don't know, changshu injection mould manufacturer is detailed to introduce the below! 1. Tubing and pipe must check regularly to prevent aging. 2. Upper die before check whether the screw hole is slippery tooth, one above for at least six sets of code, in case the code lock is not tight. 3.
upper and lower die on the die temperature machine, when the mold temperature above 70 ℃, can't use the glue tube mould, in case of high temperature hot to overflowing, high pressure oil pipe must be used. 4. Before and after the
lower die on the mold tubing, the balance must be from the machine column below a channel with a capital on top measuring needle forced abdication, in case of tubing was broken equipment or the die pressure burns. 5. At the end of the lower die in a punching die, when also near to the machine, only 20 cm above the ground, in case of rings slide tooth encounter people, above ground, in the mold to lift, people can't stand under the mold, ban pedestrians pass, to distance himself from 50 centimeters of above. 6. Under the single mode, be sure to turn off the heating tube temperature control box, switch off the electrical source valve mold temperature, after 10 points ( Check the temperature must be under 40 degrees) Tubing, heat pipes, to prevent burns. When the mould lifting to point the way to mourn die first, in case too tight, snap rings. Above is our injection mould manufacturer should pay attention to when they are in the upper and lower mould, hope you must be the installation instructions for their own safety, should also pay attention above our attention.
