Description

Secondary ejection mechanism for horn mesh of automobile door panel

Technical Field

The utility model relates to an ejection mechanism especially relates to a secondary ejection mechanism for car door plant loudspeaker mesh hole.

Background

During the design of plastic molds, especially front and rear door panels of automobiles, a horn mesh design is often seen on the door panels. Because the trumpet meshes are smaller, ejector rods which need to be arranged on the connected ribs are also smaller, under the condition, if the ejector rods are additionally arranged on the conventional ejector plate, the long and thin ejector rods need to be used, and the ejector rods are bent due to the gravity of the ejector rods and are easy to bend and deform in the ejection process. Therefore, an ejection mechanism which can not only meet the requirements of demoulding of loudspeaker meshes, but also can prevent the strength of the ejector rod from being influenced needs to be found.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model aims at providing a secondary ejection mechanism for car door plant loudspeaker mesh hole, it can satisfy loudspeaker mesh hole ejecting, can not make the ejector pin at ejecting process deformation again for whole mould structure is simpler more stable, and the cost is lower, and life is longer, is a practical and feasible mould ejecting scheme.

The technical scheme of the utility model a secondary ejection mechanism for car door plant loudspeaker mesh hole, including the hydro-cylinder board, be connected with thimble bottom plate and thimble panel on the hydro-cylinder board, be provided with the thimble between thimble bottom plate and the thimble panel, the thimble top is through ejecting piece and product contact, be connected with the ejector pin on the hydro-cylinder board, the ejector pin is connected with the connecting block after passing thimble bottom plate and thimble panel, be connected with little thimble bottom plate and little thimble panel on the connecting block, be provided with a plurality of little thimbles between little thimble bottom plate and the little thimble panel, little thimble top is located the protruding muscle intersection point of the loudspeaker mesh hole of product.

Preferably, the top of the ejector pin is inserted into an inner hole at the bottom of the ejector block, a limiting groove is formed in the upper end of the ejector pin, a through hole is formed in the side face of the ejector block, a limiting block is inserted into the through hole, the front end of the limiting block is located in the limiting groove, and the limiting block is locked on the limiting groove through a screw to be positioned.

The horn mesh secondary ejection mechanism of the utility model simplifies the space structure of the die, greatly reduces the production and maintenance cost, is convenient for maintenance and maintenance, ensures the precision, finishes the ejection process of two mechanisms by one-time ejection, improves the efficiency, and ensures the ejection process to be stable and smooth; the utility model discloses a conventional ejection mechanism's mode of thinking has been broken to the structure, has enlarged ejection mechanism's range of application, has novel innovation meaning and extensive market perspective.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 7, the utility model provides a secondary ejection mechanism for door plant loudspeaker mesh hole of car, including oil cylinder board 1, be connected with ejector pin bottom plate 2 and thimble panel 3 on the oil cylinder board 1, be provided with thimble 4 between ejector pin bottom plate 2 and the thimble panel 3, ejector pin 4 top is through ejecting 5 and product contact, be connected with ejector pin 6 on the oil cylinder board 1, be connected with connecting block 7 after ejector pin 6 passes ejector pin bottom plate 2 and thimble panel 3, be connected with little ejector pin bottom plate 8 and little thimble panel 9 on the connecting block 7, be provided with a plurality of little thimbles 10 between little ejector pin bottom plate 8 and the little thimble panel 9, little thimble 10 top is located the protruding muscle intersection point of the loudspeaker mesh hole of product.

Preferably, the top of the ejector pin 4 is inserted into an inner hole at the bottom of the ejector block 5, the upper end of the ejector pin 4 is provided with a limiting groove 11, the side surface of the ejector block 5 is provided with a through hole, a limiting block 12 is inserted into the through hole, the front end of the limiting block 12 is positioned in the limiting groove 11, and the limiting block 12 is locked on the limiting groove 11 through a screw 13 for positioning.

The utility model discloses a characteristics lie in the special construction of car door plant horn mesh department, and this mesh structure is complicated fragile again, if hard-top with ordinary thimble, the bad product of very easy top, if with the all the other departments of two hydro-cylinders top horn mesh department and car door plant respectively, then two hydro-cylinders are because can not be totally synchronous and lead to the top to hinder or even the bad product of top, consequently is a difficult point always. The utility model discloses a same hydro-cylinder comes the rest of departments of a loudspeaker mesh and car door plant, and set up

ejector pin

6 and 7 this structures of connecting block, make the length of little thimble 10 shorten as required, improve the intensity of little thimble, connecting block 7 and thimble 4 keep synchronous motion simultaneously, it comes ejecting product just also to mean

little thimble

10 and 4 synchronous motion of thimble, both guaranteed the smoothness of ejecting process, it is bad to have guaranteed again that little thimble 10 can not push up, and little thimble 10 top is in the protruding muscle handing-over point department in car door plant loudspeaker mesh, this handing-over is in the regional strongest relatively speaking intensity of loudspeaker mesh, the difficult top is bad, whole design is novel effective, safe and reliable in utilization.

The above, it is only the preferred embodiment of the present invention, not to make any restriction on the utility model, all the bases the technical principle of the present invention is to any simple modification, equivalent change or modification made by the above embodiments, still belong to the technical solution scope of the present invention.
