spheric precision molding machine-MD17-36

Product Features:

This device is suitable for the hot pressing molding of large quantities of high-precision aspheric lenses. The raw materials are placed in the mold and then introduced into the molding chamber for sequential heating, molding, cooling, and other treatments, after which they are discharged from the molding chamber. Aspheric glass production is fast and has high stability in quality. The equipment adopts an intelligent control system. In automatic mode, the mold status in the chamber is detected every time it starts, and the operating sequence is intelligently adjusted. Even in the event of a power failure, the system can remember the current molding mold status, avoiding the inability to restart directly during an instantaneous power outage. In manual mode, the mold is temporarily not recognized, and its mold number is not displayed on the industrial computer touch screen. In automatic mode, if there is an abnormality in the cylinder movement, the system automatically enters a pause state with an alarm prompt. After the fault is restored, pressing the start button resumes the operation. If the current mode cannot handle the fault, it can be switched to manual mode. Once the fault is restored, it can be switched back to automatic mode to resume operation.

Specification Parameters:

NO	Project distinction	content	Detailed specifications
1	Basic parameters	power source	Power supply: three-phase 200VAC/31KVA, three-phase 380VAC/31KVA (optional) Rated power: 31KW Starting power: 29KW; Operating power: 8~12KW
		power source	Compressed air: 0.55MPa±5%, 60 liters/min; Cooling water: 0.3MPa, 16~25L/min, 20±1℃ Nitrogen: 0.3MPa±5% (purity 99.999%), 30~45 liters/min, Oxygen content≤2ppm
		Mold specification	Diameter: φ16~φ36mm; Height: 20 ~60mm;
		working temperature	700 °, 750 °C (optional) heating time is less than 15Min
		Dimensions	2500(L)×1600(W)×2100(H) ; Approx. weight: 1420kg
2	pressure head composition	Preheating 1, 2, 3, 4, , 5, 6, 7, 8	Rapid and uniform heating of the mold and glass is controlled by the heating unit.
		Forming 1, 2	The descending mode is controlled by a precision electric proportional valve. With a resolution of 0.001 MPa, the pressure can be precisely adjusted according to the process requirements
		Cooling 1, 2
		Cooling 3, 4, 5, 6	Use the precise pressure regulating valve to control the way of descending. In order to protect the quality of the mold and the formed glass, slowly lower the temperature of the mold and glass.
3		cooling 7	Use the self-weight method of descent. In order to protect the mold and the formed glass, prevent the oxidation of the mold when it is exposed to the outside, and accelerate its cooling effect.
4		external cooling	Use the self-weight method of descent. In order to protect the mold and the formed glass, at the same time, it is fully cooled for the operator before taking it.
5	Mold transfer	transfer	Mold transfer by air cylinder and high-precision electric cylinder
6	Environmental requirements	cleanliness	Below class 10000 (recommend below class 1000, or place 100 class FFU on the operating platform to ensure local cleanliness)
6	Environmental requirements	ambient humidity; ambient temperature	30-60% , but no condensation; 22 ℃ ± 3 ℃, but no condensation
