AI Technical Summary
Traditional injection molds are prone to uneven stress when ejecting plastic parts, resulting in deformation or damage. The plastic parts are easily taken out by the mold after forming, resulting in production interruption and mold damage.
A multi-functional injection mold is designed, using four ejection rods to eject the plastic parts at the same time to ensure uniform stress. An anti-belt-piece check valve and a touch rod system are installed on the upper mold to prevent the plastic parts from being ejected from being ejected. Bring it out.
Through the synergy of the four ejector rods, we ensure that the plastic parts are subjected to uniform stress, avoid deformation or damage, and effectively prevent the plastic parts from being taken out of the mold, reducing production interruptions and maintenance costs, and improving production efficiency and product quality.

[0002] Injection mold is a tool for producing plastic products, and also a tool for giving plastic products a complete structure and precise size. The injection mold consists of two parts: a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product.
[0003] Traditional injection molds often use a single ejector rod to eject plastic parts. This method can easily lead to uneven force on plastic parts during the ejection process, which may cause deformation, damage and other problems. In addition, when the plastic parts are demolded after molding, the existing technology often faces the risk of the plastic parts being taken out by the upper mold. Once this happens, it will not only cause production interruptions and increase the cost of manual intervention, but may also cause damage to the mold and plastic parts, reducing product quality and mold life.
[0004] Therefore, it is necessary to provide a multifunctional injection mold to solve the above-mentioned technical problems. Utility Model Content

Four inclined grooves 8 are provided on the sliding block 7, each corresponding to an ejection rod 10. When the inclined groove 8 moves to the left, the four ejection rods 10 will move upward due to the slope to eject the formed plastic part. The four ejection rods 10 respectively exert force from the four corners of the plastic part, so that the plastic part is evenly stressed, maintains a good shape, and is not easily damaged.
[0029] Compared with the related art, the multifunctional injection mold provided by the utility model has the following beneficial effects:
