The Qiaopu electrical engineering department Power cord molding operation specification file

Purpose: To ensure the the Qiaopu electrical plug exposed size and other requirements to meet the requirements of product quality.
Two. Use the tools, equipment and accessories: molding machine, mold, calipers, power cord, diagonal pliers, the drying of rubber, anti-rust oil outlet plastic boxes and so on.
3. Steps:
(1) 8 minutes boot in advance, the appropriate amount of drying plastic particles into the feed opening, open electric switch temperature of 150 ~ 180 degrees Celsius, to open the cooling water; When the temperature is normal, start the motor, check the operation switch is normal; product needs, the nozzle of good mold injection port installed the corresponding mold, pay attention to whether the upper die and lower die offset phenomenon, the mold is assembled parallel with the mold frame to avoid crushed the quality of the mold and influence of injection; debug the molding machine injection pressure, injection speed, injection time, injection, packing pressure, packing time, packing speed, before and after the mold temperature, molding temperature, cooling time and other parameters.
Hit a three empty mold (injection of the compound determined); ⑵ molding and then cut a few waste line to put away try beer, confirm the basic debugging qualified, into the wire, try beer, confirm all aspects of quality to meet the requirements by the group leader and a quality control department the IPQC first article inspection to confirm qualified before normal production.
⑶ operation, put the wire in the groove straight, after the positioning of the head flush with the wire, covered with a on Molded tight, mold to mold positioning arrived tight, and then press the switch with both hands, shooting rubber quickly take the other two wires to be produced; plastic shot after, pull out the mold, holding the wire two to remove the wire to avoid the deformation of the product (such as product out of the normal deformation, the product must be back breaking is ), remove the outlet, plug the cables into the mold in sequential operations in the same way.
⑷ work before the feeding tube rubber injection press sucking back, turn off the machine. Stage of the finishing machine materials, outlet material and the rubber on the ground cleaned to distinguish the color of the plastic material into the yellow outlet hopper, not with copper wire or rubber with a metal material into the outlet box every day in the outlet hopper outlet material in bags before the afternoon work well into the designated locations; mold sprayed with anti-rust oil, keeping around the machine neat.
