Description

Technical Field

[0001] The utility model belongs to the technical field of ejection mechanism design of injection molds, in particular to a front and rear mold position accelerating ejection mechanism. Background Art

[0002] Injection molding, also known as injection molding, is a manufacturing process widely used in the plastic processing industry. It forms the desired product shape by injecting molten plastic material into a mold, then cooling and solidifying it in the mold. Injection molding can achieve automated production, fast production speed, and is suitable for mass production. Due to mass production, the cost per unit product is relatively low, especially after considering the mold cost allocation. Injection molds can be designed into complex shapes and structures, so that the products produced can be very fine and complex. Almost all thermoplastics and some thermosetting plastics can be used for injection molding, providing a wide range of choices. Injection molding can ensure the consistency and repeatability of product dimensions and ensure stable product quality. The surface of the injection molded product is smooth and can be used directly without subsequent surface treatment. Injection molding can achieve multifunctional integration of products, such as embedded metal parts, electronic components, etc. In the injection molding process, the material utilization rate is high, the waste is small, and it can be recycled, which meets environmental protection requirements. Injection molding can quickly make prototypes and shorten the product development cycle. Injection molding is suitable for the production of various products from small parts to large structural parts. In short, injection molding is an efficient, economical, flexible and environmentally friendly manufacturing process, which is widely used in many industries such as automobiles, electronics, home appliances, medical devices, packaging, toys, etc.

[0003] The ejection speed of the existing injection mold is slow during the mold opening process, and the processing fluency is low. Therefore, a front and rear mold position accelerating ejection mechanism is needed to reduce the processing interval and shorten the processing cycle. Utility Model Content

[0007] Furthermore: the mold device includes a panel, an A plate is arranged on the top of the panel, a B plate is arranged on the top of the A plate, four limiting columns are evenly fixedly arranged at the four corners of the panel, and two first buckles are symmetrically fixedly arranged on both sides of the B plate.

[0008] Furthermore: the cross section of the limiting column is circular.

The third ejector plate and the second ejector plate are controlled by the second button machine not to open the mold. When the first ejector plate and the second ejector plate move to the safety stroke (the ejected product is separated from the inner mold), the second ejector plate and the third ejector plate are forced to separate from the control of the second button machine under the guidance of the sliding column, that is, the third ejector plate stops running, and the first ejector plate and the second ejector plate continue to run until the accelerator hits the bottom of the B plate, thereby ejecting the product and ending the operation process.

The mold opening sequence is to open the A plate 102 and the panel 101 first. The A plate 102 and the B plate 103 are controlled by the first locking machine 105 to merge without opening the mold first. When the mold opening between the A plate 102 and the panel 101 is completed, the first locking machine 105 is disengaged from the control, and the A plate 102 and the B plate 103 are opened. After the templates of the A plate 102 and the B plate 103 are fully opened, the ejection system is started;
