Abstract

The utility model discloses a solid core panel mould, including terrace die and matched with ejector pin with it, the die include first die and second die, be equipped with a plurality of steps in the die cavity of second die, first die cavity is the back taper, the back taper import is less than the export, the export of back taper bottom and the die cavity size phase-match of second die, the die cavity cross-section of first die be waist drum type, the die cavity cross-section of first die in the middle of be the necking down form, the cone angle of first die be between 60-80 degrees, the conical surface import department of first die be equipped with the radius angle. The device increases the R angle, increases the pressure and improves the surface quality of products by reducing the material inlet hole, and the material inlet hole is small and the hole is large.

Description

Solid plate die

Technical Field

The utility model relates to an extrusion die designs technical field, especially relates to a solid core panel mould.

Background

Extrusion refers to a press working method in which a blank placed in a female die is pressed by a punch or a male die to cause plastic flow, thereby obtaining a product corresponding to the shape of a hole or a male-female die of a die. During extrusion, the billet generates three-way compressive stress, and even the billet with low plasticity can be extruded and formed. In the prior art, a solid plate, particularly a blank with an oxide skin, cannot remove the oxide layer in the extrusion process, and the surface quality of a product has flaws.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a solid core panel mould, through reducing into the material hole, it is big that the hole is little to go into, increases the R angle, increases pressure, improves product surface quality.

In order to achieve the above purpose, the utility model discloses a technical scheme is: the utility model provides a solid core plate mould, includes terrace die and matched with ejector pin with it, the die include first die and second die, be equipped with a plurality of steps in the die cavity of second die, first die cavity is the back taper, the back taper import is less than the export, the export of back taper bottom and the die cavity size phase-match of second die.

Further, the section of the cavity of the first concave die is waist drum-shaped.

Furthermore, the middle of the section of the cavity of the first concave die is in a necking shape.

Further, the taper angle of the first concave die is 60-80 degrees.

Furthermore, a fillet is arranged at the conical surface inlet of the first concave die.

Compared with the prior art, the beneficial effects of the utility model are that: the device increases the R angle, increases the pressure and improves the surface quality of products by reducing the material inlet hole, and the material inlet hole is small and the hole is large.

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a half sectional view of the present invention;

fig. 3 is a perspective view of the present invention.

The labels in the figures are: 1. a first female die; 2. and a second concave die.

Detailed Description

The following detailed description is provided to further explain the technical features and advantages of the present invention by referring to the accompanying drawings in combination with the embodiments.

As shown in fig. 1-3, the utility model discloses a solid core panel mould, including terrace die and matched with ejector pin with it, the die include first die 1 and second die 2, be equipped with a plurality of steps in the die cavity of

second die

2, 1 die cavity of first die is the back taper, the back taper import is less than the export, the export of back taper bottom and the die cavity size phase-match of second die 2.

Further, the section of the cavity of the first female die 1 is waist drum-shaped, the middle of the section of the cavity of the first female die 1 is in a necking shape, the taper angle of the first female die 1 is 60-80 degrees, and a fillet is arranged at the conical surface inlet of the first female die 1.

The utility model discloses the device is through reducing the material inlet hole of first die 1, and the inlet hole is little and it is big to bore, increases the R angle, increases pressure, can improve product surface quality, gets rid of the oxide layer on stock surface. The male die and the surface treatment technology thereof are the prior art or materials, and the technical personnel can directly purchase or order the male die from the market according to the required product model and specification.

The electrical components are electrically connected with an external master controller and 220V mains, and the master controller can be a conventional known device for controlling a computer and the like.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "mounted on" another element, it can be directly mounted on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

The present invention is described in detail in the above embodiments, and it should be understood that the described embodiments are not limited to the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
