Description

Hot extrusion die for producing asymmetric template profile

Technical Field

The utility model relates to a hot extrusion die that is used for occasions such as board house and factory building especially relates to an asymmetric template aluminium alloy production is with hot extrusion die, belongs to mould processing technology field.

Background

With the continuous development of society and the continuous change of market demand, market competition is more and more intense. In the fields of board houses, factory buildings and the like, a high-quality and high-standard template profile is more and more widely used, the market demand is more and more large, the template profile is particularly in short supply in the market, and the phenomenon of short supply occurs, so that great business opportunities are brought to merchants and mold manufacturers, and a plurality of manufacturers manufacture the template profile, however, on one hand, the two ends of the asymmetric template profile (such as a structure with an L-shaped cross section) are different, the flow is easily inconsistent, the problem that one end is fast and the other end is slow occurs, and the profile is deformed and bent; on the other hand, the sectional area of the section mould is larger, relatively speaking, the section mould brings great difficulty to the flatness of the section, on the other hand, the existing asymmetric template mould is unreasonable in structural design, is easy to deform due to elastic deformation during extrusion, has large front-back size difference, and has the phenomena that the front discharging is qualified and the tail discharging is small, and on the other hand, the feeding hole on the existing mould is in a profile modeling design; the small edges of the section bars are firstly quick and then slow along with the change of pressure, so that the asymmetric template is a variety with lower qualification rate in the industry all the time, the manufactured product hardly meets the requirements of customers, the cost per se is high, the die is extremely easy to deform and scrap, and the best mode for solving the problems is to shape the section bars by a section bar factory, but the cost and the labor force are increased for the section bar factory.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a can prevent that preceding back plane from warping, around avoiding size nonconformity and produce stable asymmetric template aluminium alloy production with hot extrusion die.

In order to solve the technical problem, the utility model discloses an asymmetric template aluminium alloy production is with hot extrusion die, including the die body and with the guide plate of die body cooperation installation, be provided with on the guide plate by head feeding position, middle feeding position and afterbody feeding position run through the feeding district that constitutes as an organic whole, the head feeding position in feeding district and the width at afterbody feeding position are greater than the width at middle feeding position, be provided with the one-level seam room that corresponds and shape adaptation with guide plate feeding position on the die body, the die cavity of indent in the second grade seam room of indent and the second grade seam room in the one-level seam room, thereby the guide plate makes feeding district and one-level seam room through the fixed arrangement of fastener on the die body, thereby relative formation hot extrusion die main part.

And a strip-shaped block platform is arranged on the inner side of the cavity.

And the secondary welding chamber is adaptive to the shape of the aluminum profile to be processed.

The joint of the head feeding part and the middle feeding part of the feeding area and the joint of the tail feeding part and the middle feeding part of the feeding area are provided with bending angles.

The length of the feeding part at the head part of the feeding area is larger than that of the feeding part at the tail part.

The outer edges of the head feeding part and the tail feeding part of the feeding area are provided with arc-shaped outline parts.

The utility model has the advantages of as follows:

(1) the feeding disparity between the head feeding part and the tail feeding part of the guide plate is greatly reduced, more space is provided for storing flow especially for the tail feeding part, and the phenomenon that the front is fast and the back is slow due to insufficient feeding of the tail feeding part when the pressure is low is avoided; (2) the middle feeding is reduced, and the balance effect on the feeding of the head feeding part and the tail feeding part is achieved; (3) a primary welding chamber is designed in the cavity of the lower die body, so that sufficient storage flow is ensured in each place; (4) the die cavity design of die body has the second grade profile modeling to weld the room down, has ensured flow balance, and when pressure changed, the feed was invariable all the time, made the section bar size the same around, was favorable to improving the stability of section bar, (5) the die cavity inboard is provided with and detains the platform, has avoided the section bar to arch up, guarantees that the plane degree meets the requirements.
