Abstract
The utility model discloses an ejector core for an oil pan die. The ejector core for the oil pan die comprises a base. A plurality of springs which are evenly distributed are mounted on the lower end face of the base. Mounting screws are arranged in gaps between the springs. An ejector plate is fixed on the upper end face of the base. The middle portion of the ejector plate is provided with a groove. The two sides of the groove are provided with a high table facet and a low table facet respectively. The ejector core for the oil pan die is simple in structural design; the ejector plate mounted on the base is used for improving the stability of fit between the base and a punch insert; a sliding guiding plate is arranged on the outer wall of the base, so that the sliding guiding performance between the base and a lower die base is improved, and the service life is prolonged.
Description
technical field:
The utility model relates to oil sump processing, relates in particular to a kind of oil sump mould liftout core.
background technology:
The effect of oil sump is the shell of sealing crankcase as oil storage tank, prevents that impurity from entering, and collects and store the lubricating oil flowed back to by each friction surface of diesel engine, and the part that leaves heat, prevent oil ageing.Oil sump is installed on the engine bottom, dismantled and assembled, and the shell using crankcase seals as oil storage tank.
In the design process of oil sump diel, the liftout core is crucial part, and original liftout core easily weares and teares while coordinating in punching course with between die shoe, makes and need to often be changed, thereby affect production efficiency; Fitment stability between die pad and punch insert is poor, affects the crudy of product.
the utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of oil sump mould liftout core, reasonable in design, can effectively improve and punch insert between fitment stability and increase the service life.
The technical solution of the utility model is as follows:
Oil sump mould liftout core, comprise base, it is characterized in that: described base lower surface is equipped with and is evenly distributed with some springs, be provided with mounting screw in gap between some springs, described base upper surface is fixed with die pad, the die pad middle part is provided with groove, and the groove both sides are respectively the height table top.
Described oil sump mould liftout core, it is characterized in that: the two ends of described base outer wall are provided with symmetrical slide plate, and slide plate is the stripe board vertically distributed.
The utility model has the advantages that:
The utility model structural design is simple, by being installed on the die pad on base, improve with punch insert between the stability that coordinates; Be provided with slide plate on base outer wall, the slide guide between raising and die shoe, increase the service life.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to Fig. 1:
Oil sump mould liftout core, comprise base 1, base 1 lower surface is equipped with and is evenly distributed with some springs 2, in the gap between some springs 2, is provided with mounting screw 3, after installation in punching course good stability, base 1 upper surface is fixed with die pad 4, die pad 4 middle parts are provided with groove 5, and groove 5 both sides are respectively high table top 6, low table 7, and convenient and punch insert is used in conjunction with, after punch insert is installed on die pad 4 upper surfaces, the punch insert upper surface is the level of state.
The two ends of base 1 outer wall are provided with symmetrical slide plate 8, and slide plate 8 is the stripe board vertically distributed, and while being used in combination with die shoe, slide guide is better, less to the damage of liftout core.
