The injection mold that automatically separates the channel condensate

uses the mold (Fig. 3-85) for injection molding to create simple products with rectangular cross-section. The structure of the mold ensures that the channel condensate is automatically cut off from the product when opening the mold, and will not cause residual deformation and damage to the product when unloading deep thin-walled products from the punch

the outer surface of the product is formed by the flap mold L, which is closed by the bending pin 3, and the bending pin is fixed on the fixed mold. The runner is fed from the inner surface of the product through the gate slot on the punch (core)

when the mold is opened along the B-B plane, the condensate is extracted from the sprue bushing. Failure includes complete loss of original function; When the punch is drawn out from the product, it will automatically cut off the condensate. The products get a smooth surface on the cut part of the scratch, and there is almost no tongue twister trace with the naked eye. When the mold continues to open, the bending pin 3 acts on the flap mold l to separate the flap mold and make the product fall off. The mold in figure 3-86 is used for injection molding to help you further understand the equipment molding cover products. The structure of the mold ensures that the gate is automatically cut off from the products and the products are removed from the punch (core). When the mold is opened along the I-I plane, the runner condensate is torn off from the product, then pulled out of the sprue bushing 1 and out of the groove of the material pulling plate 2. The coagulant is thrown down, the mold is opened along the B-B surface, the central push rod 4 stops moving after touching the injection top rod, and the push plate 3 takes the product off the core. In 2016, the length of Dalian sample was 250mm (for some products such as toilet paper Rongke energy storage, 200mw/800mwh energy storage peak shaving power station project is a landmark event for the utilization of all vanadium flow battery technology. This structure can make small streamline shaped parts at the bottom with the mold [(a) - early mold opening; (b) - closed mold position] shown in figure 3-87 to manufacture products with holes in the center. The structure of the mold ensures that the condensate in the sprue bushing is automatically cut off from the product during the mold opening process

when the mold is opened along the plane I-I, the template 10 is out of contact with the pin 12, the rocker 13 rotates under the action of the spring 6, the sleeve 8 moves along the longitudinal axis of the mold and cuts off the gate from the product with the blade. When the mold continues to be opened, the connecting rod 15 touches the injection set-top rod, the pushing mechanism stops, and the push rod 2 pushes the product out. Then, the central push rod 3 pushes out the condensate. When the die is closed, the sleeve 8 is reset under the action of the pin 12, the ejection mechanism is reset by the reset rod, and the central push rod is reset by the spring 11

the feature of this structure is that the sprue bushing is composed of two parts: the inactive sleeve 7 fixed on the fixed template 9; Installed on the template 10 is the movable sleeve, which is under the pressure of spring 6. The movable sprue bushing 8 is positioned in the working position (closed die position) through the rocker L 3, sleeves 4 and 5. When pin 12 moves, rocker 13 rotates relative to strut L4. (end)
