PU Refrigerator Freezer
Mold Fixture
Refigerator/freezer mold fixtures (also known as mold jigs or mold carriers) are essential components in refrigerator/freezer production lines, responsible for holding, heating, aligning, and clamping the mold sets during polyurethane injection and curing.
Introduction of Refrigerator/Freezer Mold Fixture
Structural composition: Each fixture consists of a top frame, a guide column frame, a moving frame and a lifting drive device.
Top fixture frame: The top frame consists of a top frame, a front baffle, a rear baffle and its adjustment device, a side mold locking wheel, a pneumatic mold locking device, a mold locating pin, etc.
- Top frame: welded with profiles not less than 100x200x6 and steel plates, and then processed after aging to remove stress. Used to install front and rear baffles, mold locking devices and lifting drive devices, etc.
- Front and rear baffles: made of cast aluminum plates, with copper circulating water pipes precast inside the cast aluminum template. Connected to the top frame through a hinge structure, and reliably locked with the bottom plate.
- Side panel locking wheel: used to lock the side panel
- in place, with 3-point locking on each side to prevent the middle of the side panel from bulging during foaming, ensuring the foaming quality of the box.
- Mold locking device: composed of a cylinder, a connecting rod and a locking hook, with 4-point or 6-point locking designed according to the specific situation of the mold.
Moving frame and drive system: It consists of 4 lifting cylinders, moving frame, etc.
- The left and right side panels are made of cast aluminum plates, the thickness of the two side wall panels is not less than 100mm, and the copper pipe water circulation pipeline is embedded inside.
- Box input and output device: composed of a drive motor reducer, a conveyor synchronous belt and a bracket; The left and right two synchronous belt conveyor structures are used to ensure the stability of the box conveying, and the pulley strength and rigidity are reliable.
- Bottom plate: composed of cast aluminum plate and steel structure frame. The method of sticking cast aluminum plate on the steel structure frame can ensure the strength of the bottom plate and effectively avoid the bottom plate from breaking.
- The closing height of the fixture: about 1000mm.
Lifting drive device: The fixture is driven by an upward-mounted cylinder, which has the function of fast fixture rise (fall) and slow mold closing (opening) process, so that the fixture can be lifted and lowered smoothly without shaking.
