Abstract

The invention discloses a trimming mould for an automobile oil sump, and relates to a combined mould for shaping a plate. The mould comprises upper and lower die components capable of shaping an edge slot of the oil sump; the upper and lower die components are correspondingly provided with upper and lower trimming dies; the mould also comprises an inclined hole punching device which comprises a pressing core, a punch head, a punch head driving wedge and a bump; the bump is arranged on the lower die component and matched with the inner profile of the oil sump; the bump is provided with a lower die hole corresponding to the punch head; a waste material discharge passage which is communicated with the lower die hole is arranged in the bump; the pressing core is movably connected in the upper die component through an elastic guide mechanism; a cavity which is matched with the outer profile of the oil sump is arranged in the pressing core; the punch head is slantwise movably connected in the pressing core through an elastic resetting mechanism; the punch head driving wedge is fixedly connected with the upper die component; and the top surface of the punch head is movably connected with the punch head driving wedge through a dovetail groove or T-shaped groove. The mould has reliable action, saves the space and realizes integration of the punching mould on the trimming side of the oil sump.

Description

technical field [0001] The invention relates to a plate forming die, in particular to a combined die for plate forming. Background technique [0002] In the forming process of automobile oil pan, there are two processes, one is the side groove shaping, and the other is the punching of the inclined hole on the side of the oil pan. At present, these two processes need to use two sets of molds, which are divided into two processes to complete. Low efficiency, high cost and long processing cycle. [0003] In the field of injection mold technology, a side core-pulling structure is commonly used. It has the characteristics of simple structure, reliable action and space saving. When the mold is opened, the inclined guide column drives the slider under the guidance of the guide rail to complete the core pulling by means of the mold opening force. When closing the mold, the wedge block is reset by the clamping force. The sliding stroke of the side core-pulling slider is determin...
