What are the key technical parameters of the injection molding machine?
First, the technical parameters of injection parts
(1) Screw diameter: outer diameter of the screw;
(2) Effective length of the screw: The length of the thread on the screw (MM) is often indicated by L;
(3) screw length to diameter ratio L / D: the ratio of the effective length of the screw to the diameter;
(4) The screw compression ratio V2/V1: the ratio of the first groove volume V2 of the screw feeding section to the most notched groove volume V1 of the metering section;
(5) Injection stroke: the maximum distance the screw moves, the maximum distance the screw retreats;
(6) Theoretical injection volume: the product of the JIE area of ​​the screw head and the maximum injection stroke;
(7) Injection volume: the maximum weight (g) of the PS injection once per screw;
(8) Injection pressure: the maximum pressure of the head pre-melt at the time of injection MPa;
(9) Injection speed: the maximum speed (mm/s) of the screw movement during injection;
(10) Injection time: the shortest time for the screw to complete the injection stroke during injection molding;
(11) Injection rate: theoretical volume injected per unit time; screw JIE area × at maximum speed;
(12) Screw speed: the lowest and highest speed range of the screw when the material is plasticized;
(13) Plasticizing capacity: the maximum weight of plasticized material per unit time;
(14) Screw torque: the maximum torque (N/m) of the screw drive when the material is plasticized;
(15) Elongation of nozzle: The length of the plane of the mold installation plane is extended by the nozzle.
Second, the technical parameters of the clamping parts
(1) Clamping force: the maximum locking force to overcome the expansion of the melt and lock the mold;
(2) Forming area: refers to the maximum projected area of ​​the clamping force under a certain cavity pressure;
(3) Moulding force: the maximum force for taking out the product and opening the mold;
(4) Molding stroke: the maximum distance for moving the template to remove the product;
(5) Template size: front and rear fixed mold and movable template mold installation flat size;
(6) Modulus: The maximum thickness and minimum thickness of the mold that can be mounted on the injection molding machine;
(7) Template opening distance: the maximum and minimum distance between the fixed template of the injection molding machine and the moving template;
(8) Pull rod spacing: the distance between the horizontal direction of the injection molding machine rod and the inside of the vertical direction (mm).
Third, the machine performance parameters
(1) Maximum drive power of the motor: the power (KW) of the drive oil pump motor;
(2) Fuel tank capacity: rated capacity of the hydraulic system fuel tank;
(3) Machine volume: the maximum length × height × width of the shape of the machine;
(4) Weight: The total weight of the machine.
