Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an in-mold copper nail stabilizing device. Background Art

[0002] Injection molding is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, shape and size can be set according to requirements, and the product size is precise, and it can form parts with complex shapes. The key component in injection molding is the injection mold. The injection mold consists of a concave mold and a punch. During injection molding, the concave mold and the punch are closed to form a mold cavity and fixed, and then the injection fluid is injected into the mold cavity. After the product is formed, the concave mold and the punch need to be separated, and the mold after molding needs to be taken out.

[0003] In order to increase the strength of the product or to achieve other functions such as conductivity, it is usually necessary to embed copper nails into plastic products. Therefore, when using a mold to mold such plastic products, it is usually necessary to put the copper nails into the mold, and then add injection molding liquid into the mold. As the injection molding liquid cools and forms, the copper nails can be embedded in the product. However, in the existing technology, after the copper nails are placed in the mold, they are usually not stabilized. However, during the process of adding injection molding liquid, the flow of injection molding liquid will have a certain impact on the copper nails, and the copper nails will have a greater probability of tilting or overturning, thereby reducing the qualified rate of product processing. At the same time, people usually use multiple fastening screws to fix the two molds, so people need to spend more time to remove the screws when opening the mold, thereby reducing the production and processing efficiency of the product.

[0033] Please refer to Figure 2 A symmetrical locking mechanism 5 is provided on the outer surface of the base 1. The locking mechanism 5 includes a connecting tube 501 hinged to the outer surface of the base 1 and a limiting block 504 fixed to the bottom surface of the punch body 3.

[0039] The specific implementation process of the utility model is as follows: first, the copper nail is placed into the reserved hole opened on the inner bottom wall of the concave mold body 2 until the bottom end of the copper nail contacts the arc-shaped support groove 406. At this time, the micro hydraulic telescopic cylinder 9 is started to drive the movable bar 401 to move upward. With the flipping of the transmission rod 402, the arc-shaped pad 405 can be driven to contact the outer surface of the copper nail. Under the clamping action of the arc-shaped pad 405 and the arc-shaped support groove 406 on the copper nail, the copper nail is stabilized, thereby reducing the copper nail in the injection liquid. The probability of tilting or tipping under impact further improves the qualified rate of product processing, and then the die body 2 and the punch body 3 are combined together, and the positioning cylinder 6 must be ensured to be slidably connected to the outer surface of the positioning rod 7.

[0040] When the mold needs to be opened, the limit block 1 502 is pulled upward until it is separated from the limit block 2 504, and then the connecting tube 501 is flipped over to release the limit of the die body 2 and the punch body 3. At this time, people only need to lift the punch body 3 upward to complete the mold opening relatively quickly, which effectively saves the time spent on mold opening and improves the production and processing efficiency of the product.
