Automatic die carrying die change system and method in unmanned state

Abstract

The invention discloses an automatic die carrying die change system in an unmanned state. The system comprises a die library, a die carrying vehicle, a preheating station, a transition platform, an injection molding machine and a control system. The system is characterized by further comprising an automatic charging station, a first charging module, a second charging module, RFID electronic tags,an RFID card reader, a wireless communication module, a two-dimensional code, a two-dimensional code recognizer, a walking positioning code reader, a unit position sensor, a first wireless communication module and a second wireless communication module. Due to the adoption of the structure, the automatic die change process only lasts for 3 min, the die change time is remarkably shortened, the production efficiency is improved, the labor cost is greatly reduced, and the system has the beneficial effects that the automation degree is high, the production efficiency is high, the labor cost is low, the occupied space is small, the use rate of the injection molding machine is high, and lifting is stable.

Description

technical field [0001] The invention relates to the technical field of mold processing equipment, in particular to a system and method for automatic mold transfer and mold change under unmanned conditions. Background technique [0002] At present, the processing of existing molds usually manually transports the mold from the mold warehouse to the trolley, and then manually operates the trolley to transport the mold to the preheating station, manually transports the mold to the preheating station for preheating, and then operates the trolley to transport the mold To change the mold on the injection molding machine, the mold change process is as follows: [0003] 1) After the injection molding machine is produced, manually operate the injection molding machine to clamp the mold (the mold that has been produced); [0004] 2) Open the safety door, manually disconnect the water circuit, hydraulic oil circuit, circuit and other signal connections between the injection molding mac...

AI Technical Summary

Problems solved by technology

[0013] The above process is estimated to take about 3 hours. The processing time is long, the labor cost is high, the production efficiency is low, the labor intensity is high, and the utilization rate of the injection molding machine is low.

[0014] Moreover, the traditional heavy-duty mold warehouse can only be stacked in one layer, and it is docked with the mold changing vehicle, while the heavy-duty mold is generally very large in shape and occupies a large area. The mold library is used to accommodate it, resulting in a large footprint and wasting unnecessary space

[0015] In addition, the elevating mold changing vehicle for heavy molds usually uses a heavy-duty screw elevator, and the way of inversion is used to meet the minimum table height and maximum lifting range, because the elevating mold changing vehicle generally only works when it is lifting. Carrying the mold on one station table will cause uneven load on the whole table, so the elevator does not have high synchronization and lateral force resistance

[0016] After retrieval, CN108861399 discloses a non-contact power supply intelligent heavy-duty mold transfer vehicle, a method for transporting and changing molds. When transporting and changing molds, two transfer vehicles are required. When the first transfer vehicle hooks the new mold through its push-pull mechanism Mold, pull it on the first transfer vehicle, then the first vehicle follows the second empty transfer vehicle out of the mold warehouse, and takes the second transfer vehicle on the main road to complete the mold unloading operation, the second transfer vehicle The car runs along the designated route to the equipment that needs to change the mold. When turning is required in the traveling route, the hydraulic lifting mechanism lifts the transfer car body as a whole, and the rotating mechanism rotates to change the movement direction of the transfer car body, thereby realizing the turning operation. When the second transfer car runs along the designated route to the equipment that needs to change the mold, the push-pull mechanism inside the second transfer car pulls the new mold into the second transfer car and drives out, and then the first transfer car The car moves to the equipment, and the new mold is pushed to the inside of the equipment through the push-pull mechanism, thereby completing the replacement of the old and new molds. The substantive shortcomings of this method of transporting the mold and changing the mold are: two transfer vehicles are required, and the cost of the mold changing equipment is high; At this time, the transfer car needs to stop, and then the whole body is lifted by the hydraulic lifting mechanism, and the rotating mechanism rotates. The turning time is long, the structure is unreasonable, the work efficiency is low, and manual tracking operation is required, and the labor cost is high.
