Problems solved by technology

For trimming molds with higher and higher requirements on the appearance quality of the appearance parts, the waste materials cannot be cut at the same time. The tearing process will damage the product to a certain extent, and the powder generated by the trimming will be brought to the board, stamping pits are left on the board, affecting the quality of the board and causing defects in the appearance of the board

Embodiment Construction

[0020] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0021] This floating waste knife mechanism of the present invention, as figure 2 , 3 As shown, it is arranged on the upper mold of the trimming mold. The floating waste knife mechanism includes a floating waste knife 41 that can move up and down relative to the waste knife 3 of the lower mold below. The mold scrap knife 41 acts as a pressure cylinder 45 which separates the panel product from the scrap here.

[0022] In the present invention, if figure 2 , 3 As shown in , the floating waste knife 41 is fixedly connected to the upper mold through the fixed seat 43 , and the inner side of the fixed seat 43 is provided with a limit card platform for clamping the floating waste knife 41 . The upper end of the floating waste knife 41 is provided with a corresponding locking convex edge that is ...

Abstract

The invention discloses a floating waste cutter mechanism and a trimming method of a trimming mold provided with the floating waste cutter mechanism. The floating waste cutter mechanism is arranged onan upper mold of the trimming mold, and is characterized by comprising a floating waste cutter cutter which is opposite to a lower mold waste cutter at the lower portion and can move up and down, andthe floating waste cutter is provided with a pressure cylinder for driving the floating waste cutter to move downwards, and act with the lower mold waste cutter so as to separate a plate piece product from waste. The floating waste cutter mechanism and the trimming method of the trimming mold provided with the floating waste cutter mechanism are simple in structure, so that the waste can be conveniently separated from the product through cutting, the product quality can be protected, the appearance defect of a plate piece can be avoided, and the mechanism and the method have good applicationprospects.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, and more specifically relates to a floating waste knife mechanism and a trimming method of a trimming die provided with the mechanism. Background technique [0002] Since the exterior design of automobiles is more dynamic and streamlined in the design of automobile models, the requirements for the appearance quality of the products are getting higher and higher in the trimming process of automobile casting dies and stamping dies. [0003] In the current trimming mold design process, most of them still use the conventional upper mold cutter block and lower mold insert to assist the lower mold waste knife to complete the trimming work content. Such as figure 1 As shown, when the pressing core presses the material, the first trimming knife block 1 and the second trimming knife block 2 continue to move downward and complete the trimming with the lower mold insert, and the first trimming knife ...
