What should be paid attention to during the installation and debugging of automatic mold changing and automatic mold warehouse system?

Matters needing attention in installation and debugging of automatic die changing+die stereo warehouse system

A, early site and foundation construction attention

Ground bearing standard

The mold depot and the track area of the mold changing trolley must be reinforced by bearing, and the heavy injection molds should be piled up in a centralized way. The ground bearing capacity should be reserved according to the maximum mold weight to prevent settlement and inclination.

Site space planning

Reserve the entrance and exit passage of the mold, forklift operation area, maintenance space and electrical control cabinet, and confirm that the width and height of the door body meet the maximum mold passage.

Horizontal and datum positioning

The whole track and the shelf base of the vertical warehouse shall be leveled uniformly, and the plane error shall be controlled within 3mm, so as to avoid the deviation of the stacker and the deviation of mold taking.

environmental requirement

Keep away from the heat source, oil pollution and dust concentration area of high-temperature injection molding machine, and do a good job of dust prevention, oil prevention and moisture prevention, and avoid water vapor erosion of electrical components.

Second, the mechanical structure installation and debugging points

Vertical warehouse shelf assembly

The vertical columns and horizontal beams are consistent, the interlayer spacing is set strictly according to the height of the mold, the load-bearing beams are fastened in place, and the anti-falling limit is installed to prevent the mold from slipping.

Travelling mechanism of stacker

Guide rail splicing seamless, straightness and parallelism correction; The gap between the walking wheels is moderate, and there is no jamming and abnormal noise in operation, and the left and right brakes are synchronized.

Lifting mechanism

The chain/wire rope shall be elastic and even, and the lifting shall be smooth without jitter. Limit switches and upper and lower limit anti-collision devices shall be calibrated in advance, so as to prevent the risks of jacking and die dropping.

Debugging of automatic die changing trolley

The trolley is accurately positioned and aligned with the center of the injection molding machine mold base; The locking die buckle and hydraulic clamping mechanism can be opened and closed smoothly, and the clamping force can be adjusted uniformly.

Mould positioning datum

Unify the standards of lifting lugs, reference holes and locating grooves of the mold, and ensure that the standards of storage in the library and installation of the machine are consistent, so as to avoid the deviation of mold replacement and alignment.

Butt transition position

The whole docking process from the warehouse exit position to the trolley to the injection molding machine mold area is smooth, with no height difference, and the mold translation is free from collision and deviation.

Third, the hydraulic and pneumatic system debugging

The pressure of the hydraulic station is adjusted to the standard value, with no oil leakage, stable pressure and smooth switching between fast and slow speed.

The action sequence of the air cylinder and the clamping cylinder is set reasonably, and the buffering force is moderate, so as to avoid damaging the die core of the die by impact.

The air source is equipped with a drying and filtering device to prevent water vapor and oil pollution from affecting the service life of pneumatic components.

Four, electrical and control system debugging

Strong and weak current shall be separately wired, and the lines shall be fixed and regular. Special cables shall be used in the high-temperature resistant area for grounding protection.

Photoelectric induction, position sensor and scanning code identification device are precisely aligned, and the signal is sensitive without misjudgment.

Logic check of PLC program action: warehousing → access → warehousing → transshipment → automatic die changing → returning to the warehouse.

The function test of emergency stop button, regional safety door lock and infrared protective fence, and the safety interlock must be effective.

Touch screen parameter setting: mold number, warehouse number, weight specification and machine number are bound and entered one by one.

V. Key safety protection matters

Divide the safe operation area and the forbidden area for equipment operation, and install protective fences, warning signs and audible and visual alarm.

After the no-load test run is correct, the light mold → standard mold → heavy mold shall be tested step by step.

Anti-falling, anti-dislocation, anti-over-travel, power-off and self-locking functions are all debugged in place.

Personnel maintenance mode and automatic operation mode are strictly distinguished to prevent accidental startup.

Six, die matching standardization attention

The thickness, lug size, positioning hole and clamping groove specifications of the whole factory are unified, which is suitable for automatic clamping and transshipment.

The mold is equipped with identification bar code/chip to realize automatic identification of the system and automatic allocation of locations.

The water and oil joints of the mold are oriented uniformly, and they can be docked quickly after automatic mold change.

Seven, online linkage debugging

The mold warehouse system communicates with injection molding machine and manipulator to realize automatic transfer of molds on demand.

Debug the speed and time sequence of die changing, shorten the overall die changing time and meet the rhythm of mass production in the workshop.

Data is connected with MES system to realize automatic management of mold inventory, use frequency and maintenance cycle.

Eight, commissioning and acceptance

Run in circular-flow with no load for 8 hours continuously, and check abnormal sound, jamming and positioning deviation.

Batch access of real molds, automatic mold changing and repeated testing to confirm the stability.

Organize debugging records, list of wearing parts, daily maintenance procedures, and complete operator training.
