Inner core-pulling die mechanism with bent pin

Abstract

The invention provides an inner core-pulling die mechanism with a bent pin. The die mechanism provided by the invention comprises spare parts such as a fixed template, a stop block, a swing hook, a stripper plate, a rotation shaft, a spring, a roller wheel, a bent pin fixing plate, a push rod, a moving template, the bent pin, a side core slide block, a combined convex die, and the like; and the connection mode for the spare parts is as follows: the side core slide block 2 is arranged in the combined convex die 1, the bent pin 3 is in sliding fit with the side core slide block 2, and simultaneously the bent pin 3 is tightly fixed on the bent pin fixing plate 6; the moving template 4 is fixedly connected with the bent pin fixing plate 6, a support plate and a moving die base plate through screws; the slant surface of the swing hook 11 is contacted with the roller wheel 7 and is supported by the spring 8; and the rotation shaft 9 is in sliding fit with the swing hook 11. When the die is designed, the locking mechanism is inconvenient to set, and the side pressure of a molten material on a side core when injection or casting is overcome by means of the bending intensity of the bent pin, therefore, the mechanism is only applied to the occasion that the sectional area of the side core is small, and is simultaneously applied to increasing the sectional area of the bent pin.

Description

technical field [0001] The invention relates to metal die-casting molds and plastic injection molds, and is a mold mechanism with inner core pulling of bent pins. Background technique [0002] At present, in the design and manufacture of the mold, the installation of the bending pin can also be outside the mold or inside the mold, but generally it is more often installed outside the mold, which is more convenient for installation, but the product has an inner concave. It is convenient to take out the product and form the product. At this time, it is difficult to form the product and take off the product when the bending pin is installed outside the mold. In order to better form the product and take off the product, I now combine my years of production and design experience in the design line to provide the following one. Organization, for the reference of the mold industry. Contents of the invention [0003] The present invention provides a core-pulling mold mechanism ins...
