Set the Ejector Pin to be associated with the insert point. This option cannot be shared with the following option keep associated with insert points. 1 is the coordinate value is a multiple of 1 2 is the coordinate value is a multiple of 2, and so on. 0.1 is the coordinate value to retain 1 digit after the decimal point.
For example,0.01 is the coordinate value to retain 2 digits after the decimal point. Set the number of digits to retain the decimal point according to certain rules, or discard the decimal point. If the Ejector Pin is not in Z-axis foward direction, users should specify insert face, ZW3D can automatically infer the value of relevant parameters. The default setting is the bottom of the thimble plate. If the point is not on the insert face, it will be projected to insert face along Z direction. The object between Ejector Pin insert face and the shape(including the shape) will participate in the pocket creat operation. Select the plate where Ejector Pin will end to define the boundary of the intersection entity. Users can customize Ejector Pin according to ZW3D parameter driving rules, use it after registering in the configuration file. ZW3D Ejector Pin function help users automatically place Ejector Pins on the thimble board, and help users automatically calculate the height of Ejector Pins. You are welcome to contact by to get a quote for the plastic mold or products.In mold, Ejector Pin is also called pushrod, which is used to separate the molding plastic products from the mold. The ejector pins cannot be placed in some placesįor plastic parts with appearance requirements, it can not be in the appearance surface, and we should adopt other ejection methods. For transparent plastic parts, it can not be arranged in the part that needs to transmit light.For example, in the larger plane of the cavity, although the packing force of the rubber part is small, it is easy to form a vacuum, which leads to an increase in the demolding force. In order to exhaust during ejection, it should be arranged in the part which is easy to form a vacuum. Consider the exhaust function of the ejector pin.Consider the distance between the ejector pin and the waterwayĪvoid affecting the processing and water leakage of the waterway.And the top surface of the ejector pin should not touch the cavity side. When layout the ejector pin, we should avoid those sharp and thin steel. When we use it, try the insert form to facilitate processing. In the deep rib (depth ≥20mm) or it is difficult to arrange the dome ejector pin, we should adopt flat ejector pins. Flat ejector pin should be chosen in some cases.The top surface should be as smooth as possible, and we should arrange it in the structural part of the rubber with better force. Avoid arranging ejector pinon the inclined surface or overstepping.In addition, try to ensure the ejector pin on both sides of the column position. The ejector pin on both sides of the rib and column should be arranged symmetrically as much as possible. The effective places include the rib, column, step, metal insert and other complex structures. The ejector pin should be set in effective places.The demolding force for complex structures is relatively large, so the number of ejectors should be increased accordingly. 1.The ejector pin layout should make the ejection force as balanced as possible When the mold opens, the plastic product must be retained on the mold half (usually the core) with the ejector mechanism that is used to release the plastic product. The quality of the ejection determines the quality of the plastic product. The ejection of a plastic product is the last step in the plastic injection molding process. … Once the mold is opened, the pins extend into the mold cavity, push the part out, and then retract, allowing the mold to close and be refilled. They apply a force to eject a part from the mold, and in some cases can leave marks. Ejector pins are the “bouncers” of the injection molding world.
