When the cavity is deep, it can be "reservoir" way cool. Partially processed normally require cooling sank the first hole, between holes spaced copper pe, "reservoir" take 12,16,18,20 diameter of 4, the specific size according to the actual situation. Door) when it comes to the fine and deep type cores, If you can not cooled by conventional cooling cabbage pe, consider using heat stick for cooling. Placed in the core of an elongated rod cooling, so that the bottom of the cooling rods have enough space to store the coolant, Fig. 4 refers to the storage space. Only Team 611 \ 16 flood wildfire Chinese version 5 knife ten [sub model training base and surface sample from X 6.0 system out of the top of the top of the system is the last link of mold opening, as well as injection molded plastic products from the cavity after top of the action. Top of the system design is reasonable or not is the key to the product quality. Wall thickness, rigidity difference thimble arranged in strength, rigidity of the top portion of the thimble is to be set when positioning structure pe pipe curved surface features to prevent thimble rotation. Thimble top surface should be flat, to avoid the ramp portion is arranged thimble, shown in Figure 2-41. Thimble should try to avoid laying on an incline, (fighting) for Transparent plastic products need attention thimble marks affect the appearance pe plate, thimble arrangement does not affect the need; ^ BU concept of the site, as shown in Figure 2-42. Thimble can be arranged at the outer wall thicker, this method is suitable for use in a small mold. When the mold is large, if smaller diameter thimble, at the top of the process is easily deformed, then you can use a thimble arranged. Transparent products thimble arrangement Method 2 (c) of the thimble and the cooling water should be kept a reasonable distance, to avoid a collision between the two. When there is enough space layout thimble thimble need to use a larger diameter to ensure adequate strength thimble. Preferred standard size of a thimble, try not to use non-standard or less thimble and thimble specifications should be minimal. Dome of the needle is the most common thimble type is the most frequently used thimble. Dome of the Dome of the needle into ordinary needle and have entrusted the two domes. pe protective film | Xili pe | Gary trade provided by the Shenzhen Municipal Trade Co., Gary.
