Abstract

The utility model relates to an extruding mould of an internal retainer, which belongs to the extruding mould of an internal retainer for a front overhang soft pad of an engine. The utility model provides the extruding mould of an internal retainer with high productive efficiency. The utility model comprises a male mould and a female mould, and is characterized in that the bottom of a mould shank of the female mould is provided with an open groove which penetrates through a positioning pin. A positioning pin of an upper compression mould below the mould shank is fixed in a groove of the mould shank, and the middle of the bottom of the upper compression mould is provided with a hollow truncated cone. A lower spacing collar and an upper spacing collar are orderly arranged above a base arranged at the upper part of a bottom board of the male mould, and the middle of the upper spacing collar, the lower spacing collar and the base is provided with a mold core, the bottom of which is provided with a discharge port. The upper part of the mould core is in a frustum cone shape.

Description

The extrusion die of interior guard ring

Technical field:

The utility model belongs to the extrusion die of the interior guard ring of engine front overhang cushion.

Background technology:

Guard ring is generally steel-casting at present, but sand holes are easily arranged, and insufficient strength; In addition, because of size has error, must be through machining, therefore, production efficiency is low.

The utility model content:

The wood utility model is exactly at the problems referred to above, and the extrusion die of the high interior guard ring of a kind of production efficiency is provided.

The utility model adopts following technical scheme: the utility model comprises punch, die, its structural feature is that the bottom of the die shank of die has the open slot by alignment pin, the alignment pin of the last extrusion die of die shank below is fixed in the groove of die shank, and the centre of the bottom of last extrusion die has the open circles frustum; The top of the base plate upper base of punch has lower limit circle, upper limit circle successively, and the centre of upper limit circle, lower limit circle, base is provided with the core rod that the bottom has discharge port, and the top of core rod is truncated cone.

The beneficial effects of the utility model:

Because the utility model is an extrusion die, the workpiece that extruding is come out does not have sand holes, and intensity is good, but other machining has been removed in the dimensional accuracy one-time-reach-place from, therefore, and the production efficiency height.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

The utility model comprises punch 1, die 16, the bottom of the die shank 14 of die 16 has the open slot 12 by alignment pin 15, the alignment pin 15 of the last extrusion die 9 of die shank 14 belows is fixed in the groove 13 of die shank 14, and the centre of the bottom of last extrusion die 9 has open circles frustum 11; The top of base plate 2 upper base 3 of punch 1 has lower limit circle 5, upper limit circle 6 successively, and the centre of upper limit circle 6, lower limit circle 5, base 3 is provided with the core rod 7 that the bottom has discharge port 4, and the top of core rod 7 is the frustum of a cone 8 shapes.

Narrate a course of action of the present utility model below:

At first, select extrusion die 9, the alignment pin 15 of last extrusion die 9 falls in die shank 14 grooves 13 by open slot 12, and rotation alignment pin 15 just can be fixed on the die shank 14 going up extrusion die 9; For binding, the hollow cylinder mold that the other end is uncovered places on the core rod 7 an end; Die shank 14 presses down, compacting mold moulding between the open circles frustum 11 of last extrusion die 9, the frustum of a cone 8 of core rod 7; Die shank 14 lifts, and takes out workpiece 10, core rod 7, upper limit circle 6, lower limit circle 5, and discharge port 4 places and unloads in the instrument clamp then, takes out workpiece 10 and gets final product.
