Abstract
The utility model provides a hot extrusion die, which relates to the technical field of die used for the processing of hot extrusion pipes of aluminium and aluminium alloy. A female die is provided with a female die welding chamber and a forming through hole; the female die welding chamber is internally provided with a circular flow blocking wall which is connected with the end of the forming through hole; a male die is uniformly provided with at least two material inlet chambers; bridges are arranged among all material inlet chambers; drips are respectively arranged on the bridges corresponding to the female die; the male die is also provided with a forming core which faces to the female die; the male die is provided with a male die welding chamber which faces to the female die. Hydrostatic pressure in the welding chamber and the welding time are increased, the welding performance is improved and the strength at the welding seam is enhanced. Therefore, the pipes which are extruded by adopting the die of the utility model greatly improve the strength of the pipes at the welding seam and are beneficial to the subsequent processing by the user.
Description
Technical field
The utility model relates to the hot extrusion tubing die for processing technical field of aluminium and aluminium alloy moulding.
Background technology
Adopt mould to carry out hot extrusion in the moulding of aluminium and aluminium alloy pipes mostly, mould is made up of relative formpiston and former usually.Be provided with the seam chamber in the die cavity of former, former is also offered forming through hole, and the inner of forming through hole is connected with the seam chamber; Formpiston is evenly equipped with feed cavity, between each feed cavity bridge is set, and relative former is provided with and drips on the bridge, and formpiston is provided with the forming core head towards former, and the free end of this forming core head is inserted into the front portion of the forming through hole of former.When the pipe material of hot melt after each feed cavity of formpiston is converged by dripping, in the indoor seam of the seam of matched molds, in the anterior moulding of forming through hole, under the continuous promotion of charging, the tubing of moulding is outwards pushed by the forming through hole of former again.
Because mould its specific structure, formed " diffluence combination die " formula mode of production, make and have 3 to 4 " seam seam " on the cross section of tubing, and the intensity of these commissures than other parts a little less than, make the user when following process such as rolling, enlarging, cracking phenomena occurs in the commissure easily, have a strong impact on user's product quality and service life thereof.
The utility model content
The utility model purpose is to design a kind of production hot-extrusion mold that strengthens tubing seam performance.
The utility model comprises former and formpiston, and described former is provided with former seam chamber and forming through hole, annular choked flow wall is set in that the former seam is indoor, and described choked flow wall is connected the end of forming through hole; Uniform at least two feed cavity of described formpiston are provided with bridge between each feed cavity, are provided with respectively with respect to former seam chamber on the bridge and drip, and also are provided with the forming core head towards former on the formpiston, and the formpiston seam chamber towards former is set on formpiston.
Owing to designed the choked flow wall, increased the seam time, improve the seam performance; Owing to be provided with formpiston seam chamber, increased the seam total depth after merging with former seam chamber, increase the indoor hydrostatic pressure of seam, thereby increased commissure intensity.So, adopt the tubing of the utility model mould extruding to improve the intensity of tubing commissure greatly, be beneficial to user's following process.
The utility model angle design of also will dripping is 40～45 °, improves the metal flow performance, further improves the intensity of product seam place.

Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of formpiston.
Fig. 3 is the left-hand view of Fig. 2.
Fig. 4 is the dextrad view of Fig. 2.
The specific embodiment
As shown in the figure, the utility model is made up of former 1 and formpiston 2, is provided with the concavo-convex step of mutual interlock between the two, also interfixes by bolt 3 during use.
Former 1 is provided with former seam chamber 1-1 and forming through hole 1-2, and annular choked flow wall 1-3 is set in former seam chamber 1-1, and choked flow wall 1-3 is connected the end of forming through hole 1-2.
Claims (2)
1, a kind of hot-extrusion mold comprises former and formpiston, and described former is provided with former seam chamber and forming through hole, uniform at least two feed cavity of described formpiston, between each feed cavity bridge is set, is provided with respectively with respect to former seam chamber on the bridge and drips, also be provided with core print on the formpiston towards former; It is characterized in that: annular choked flow wall is set in that the former seam is indoor, described choked flow wall is connected the end of forming through hole; Formpiston seam chamber towards former is set on formpiston.
2,, it is characterized in that the described angle of dripping is 40～45 ° according to the described hot-extrusion mold of claim 1.
