Description
Technical Field
The utility model relates to an extrusion structure especially relates to a local extrusion constructional device.
Background
In the die casting production, the local high-frequency leakage position of the product needs to be improved by adopting a local extrusion device. Due to the structural limitation of the die, the insufficient structural space of the local extrusion device is a problem troubling die factories.
Disclosure of Invention
In order to solve the problem, the utility model provides a local extrusion constructional device provides the local extrusion constructional device that can install in the not enough structure in space. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a local extrusion constructional device, includes extrusion round pin, extrusion round pin sleeve pipe, extrusion hydro-cylinder, extrusion round pin connecting sleeve and hydro-cylinder connecting rod, the extrusion hydro-cylinder be connected with the movable mould frame through the hydro-cylinder connecting rod, the middle part of hydro-cylinder connecting rod is connected with the thimble board, extrusion round pin sleeve pipe cover establish on the extrusion round pin, the extrusion round pin is connected with the extrusion hydro-cylinder through extrusion round pin connecting sleeve.
Further, the number of the oil cylinder connecting rods is set to be 4.
Furthermore, the extrusion pin connecting sleeve is connected with the extrusion oil cylinder in a threaded connection mode.
Compared with the prior art, the utility model discloses following beneficial effect has: the extrusion pin connecting sleeve is adopted to improve the bending strength of the extrusion pin, and the problems that the space for installing the extrusion device between the movable mold frame and the ejector plate is insufficient, and the extrusion device needs to be added above the ejector plate in a long distance are solved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the extruded structure;
in the drawings: 1. the extrusion pin, 2, extrusion pin sleeve, 3, extrusion hydro-cylinder, 4, extrusion pin connecting sleeve, 5, hydro-cylinder connecting rod, 6, movable mould frame, 7 and ejector plate.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described with reference to fig. 1 and 2 and the specific embodiments.
As shown in the attached drawings 1 and 2, the local extrusion structure device comprises an extrusion pin 1, an extrusion pin sleeve 2, an extrusion oil cylinder 3, an extrusion pin connecting sleeve 4 and an oil cylinder connecting rod 5, wherein the extrusion oil cylinder 3 is connected with a movable mold frame 6 through the oil cylinder connecting rod 5, the middle part of the oil cylinder connecting rod 5 is connected with an ejector plate 7, the extrusion pin sleeve 4 is sleeved on the extrusion pin, and the extrusion pin 1 is connected with the extrusion oil cylinder 3 through the extrusion pin connecting sleeve 4.
Further, the number of the cylinder connecting rods 5 is set to 4.
Further, the extrusion pin connecting sleeve 4 is connected with the extrusion cylinder 3 in a threaded connection manner.
The utility model discloses a theory of operation and working process as follows: the oil cylinder connecting rod 5 is used for connecting and fixing the extrusion oil cylinder 3 and the movable die frame 6 on the ejector plate 7, and because the length of the extrusion pin 1 is too long, the extrusion is easy to bend due to independent stress extrusion, and the production beat of die casting is influenced, the extrusion pin connecting sleeve 4 is adopted and sleeved outside the extrusion pin 1 and is in threaded connection with the extrusion oil cylinder 3 together with the extrusion pin 1, and the bending strength of the extrusion pin 1 is improved. The proposal solves the problems that the space for installing the extrusion device between the movable mold frame 6 and the ejector plate 7 is not enough, and the extrusion structure must be added above the ejector plate 7 which is far away.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
