Plastic mold comprehensive detection device and detection method

Abstract

The invention relates to a plastic mold comprehensive detection device which comprises a movable box body in which a cooling system test system and a push-out mechanism test system are disposed. The cooling system test system comprises a pressure test system, a flow test system and a blowing treatment system. The cooling system test system includes a water tank, and a circulating pump and a booster pump which are connected to the water tank. The circulating pump is connected with a flow sensor. The booster pump is connected with a pressure sensor. The circulating pump and the booster pump areconnected with the water inlet valve and the water return valve of a mold through pipelines respectively. An air compression device is connected to the water inlet of the mold through a blow valve toblow air. The push-out mechanism test system includes an oil tank connected to an oil cylinder chamber under the control of a solenoid valve so as to control the movement of the push-out mechanism ofthe mold. The plastic mold comprehensive detection device also includes a PLC control system. The plastic mold comprehensive detection device is flexible, and convenient and fast in mold detection, greatly reduces production cost and production cycle, and has a great promotion value.

Description

technical field [0001] The invention belongs to the field of testing equipment, and in particular relates to a comprehensive testing equipment for plastic molds. Background technique [0002] In the processing and production of plastic molds, after the plastic mold is assembled, it is necessary to test the cooling system, the ejection mechanism, the limit switch of the ejection, etc., and it can only leave the factory when the production requirements are met. Because the cooling system has a great influence on the surface quality of the final product, such as surface finish, residual stress, crystallinity, thermal bending, etc., it has a more direct impact on the ejection temperature and cycle time, and ultimately affects the production cost. The ejector mechanism is an important mechanism to ensure the normal production and the smooth demoulding of the product, so the above tests are very important in production. At present, the cooling system detection in the industry gen...
