Hydraulic test method for die

Abstract

The invention relates to a hydraulic test method for a die. By the method, a hydraulic system and an ejection system of the die can be tested under the condition that assembling the die is not required to be assembled in an injection molding machine. The method has the advantage that when the die is assembled, the trouble and loss which are caused by reworking after the die is assembled completely are avoided by judging whether an ejection mechanism of the die has defects or not, an oil cylinder has an oil leak phenomenon or not and a top block is loosened or dangerous or not.

Description

Technical field: [0001] The invention relates to the technical field of mold testing, in particular to a mold hydraulic testing method for testing a mold hydraulic system and an ejection system. Background technique: [0002] At present, when mold manufacturers test the mold, especially the hydraulic system and ejection system of the injection mold, they can only test it on the injection molding machine, and the mold test on the injection molding machine has the following disadvantages: [0003] 1. When the mold is tested on the machine, if the mold has the following problems: first, there are defects in the ejection mechanism, such as impurities that are not cleaned up during the mold assembly, resulting in problems with the ejection, and it is impossible to continue the mold trial; 2. The quality of the rubber ring in the mold cylinder is not up to standard, resulting in oil leakage in the mold cylinder; 3. When the top block of the mold is loose or dangerous. [0004] Th...

Problems solved by technology

[0003] 1. When the mold is tested on the machine, if the mold has the following problems: first, there are defects in the ejection mechanism, such as impurities that are not cleaned up during the mold assembly, resulting in problems with the ejection, and it is impossible to continue the mold trial; 2. The quality of the rubber ring in the mold cylinder is not good enough, resulting in oil leakage in the mold cylinder; 3. When the top block of the mold is loose or dangerous

[0004] Then it is necessary to unload the mold from the machine and re-adjust and process the mold. The troubles and losses caused by rework are huge, especially for large molds, such as bumpers, dashboards, door panels, sub-dashboards, etc. Mold, if you wait until this type of large mold is tested on the injection molding machine and then find out that there is a problem with the hydraulic system and ejection system of the mold itself, you need to unload the mold for adjustment and treatment. This trouble and the loss caused are very large. of

[0005] 2. After the mold is tested on the machine, it is usually shipped after several proofings and customer acceptance. For some potential problems of the mold, it can only be cleared after the customer purchases the mold and goes back to produce a certain number of products or use it for a certain period of time. It is found that mold manufacturers often need to send technicians to carry out repairs, which will cost a lot of money and time, and also bring delays in production time to customers, cause economic losses, and give customers a bad impression
