Embodiment Construction
[0020] In order to allow those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as Figure 1~5 As shown, a new type of in-mold tapping machine includes an upper die base 1, a pressing block 2, a lower die base 3, a lower die backing plate 4, a lower die lifting plate 5, a transmission mechanism 6, a driving mechanism 7, and a tapping mechanism 8. The drive mechanism 7 includes a screw fixing bracket 76 that can move up and down in the vertical direction. A multi-head screw 75 is provided below the screw fixing bracket 76. A multi-head nut 72 that is threadedly engaged with the multi-head screw 75 is provided below the multi-head screw 75. The nut 72 is connected with the drive gear shaft 74 through a keyway, the drive gear shaft 74 is provided with a drive gear 73 outside, and the drive mechanism 7 is provided with a bull n...

A novel in-mold tapping machine comprises an upper mold base, a lower mold base and a drive mechanism. The drive mechanism comprises a screw fixing support capable of moving along the vertical direction. A multi-thread screw and a multi-thread nut meshed with the multi-thread screw are arranged below the screw fixing support successively. The multi-thread nut is connected with a drive gear shaft through a keyway, a drive gear is arranged on the outside of the drive gear shaft, a transmission mechanism matched with the drive gear is arranged above a lower mold lifting plate, and the transmission mechanism is connected with screw taps. The upper mold base is driven to act and moves downwards to compress the screw fixing support to move downwards, the multi-thread screw moves downwards together to drive the drive gear shaft and the drive gear to rotate, and accordingly, gear sets of the transmission mechanism are driven to rotate, and the screw taps are driven to rotate to perform tapping downwards finally. According to the tapping machine, the drive mechanism and the transmission mechanism can be used repeatedly, the application range is wide, the cost is low, the stress on the lower mold lifting plate is uniform, the service life of the screw taps and the product yield are effectively increased, and the pressing efficiency is high.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to an in-mold tapping machine capable of realizing in-mold automatic tapping. Background technique [0002] Cold stamping hardware is widely used in industrial production. When some products require screw holes, tapping machines are installed in the stamping die to improve production efficiency and ensure product quality. [0003] The existing in-mold tapping machine is mainly composed of a gear box and a screw rod. The gear box is installed on the concave plate. When the slider of the punch press goes down, the screw rod pushes down the nut in the gear box to rotate, thereby driving the tap on the product. Tapping, when the slide block of the punch press goes up, the screw pulls up the nut in the gearbox to reverse, and finally drives the tap to exit the product. [0004] The above-mentioned existing in-mold tapping machine has the following disadvantages: 1. The length of the screw...
