Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. 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.

Common matched upper die and lower die generally have fixed die cavities, can only forge an aluminum alloy with a fixed shape, and need match heating devices respectively for dies with different die cavities, so that the production cost is high, and unnecessary waste is caused.

For this reason, as shown in fig. 1 to 7, the utility model provides a forge split type heating die aims at through adopting split type structure, and the heating can public upper and lower die holder, and only need change during the switching product possess different mould chambeies about the module can, not only can material saving, reduction in production cost, the indirect heating module of mode through the heat transfer moreover can make the plastic alloy in it be heated evenly, improves the product quality. Specifically, the method comprises the following steps:

this split type heating die is provided with accordant connection's last module 3 and lower module 4 including upper die base 1 and die holder 2 that mutually support between upper die base 1 and die holder 2, forms between last module 3 and lower module 4 and is used for the fashioned moulding chamber 5 of blank. And a heating mechanism for indirectly heating the blank is laid on one side surface of the upper die holder 1 and the lower die holder 2 close to the plastic cavity 5.

Preferably, the heating mechanism is an electric heating pipe 7, and the electric heating pipe 7 is spirally arranged in the upper die holder 1 and the lower die holder 2 respectively, so that more heating areas are provided, and the heating uniformity of the die is improved.

This allows a common set of upper and lower die beds 1 and 2 for heating, provided that the upper and lower modules 3 and 4 with different plastic cavities 5 are replaced. Compared with the original integral die, the mode saves half of materials and greatly reduces the die processing cost. And through the indirect heating mode, the even degree that moulding blank was heated has been improved.

One difficulty to be solved by the split type die is how to quickly and accurately realize the connection between the upper die holder 1 and the lower die holder 2 and the corresponding upper die block 3 and the lower die block 4 so as to improve the installation efficiency.

The utility model discloses a mode be: a plurality of positioning grooves 6 are arranged on the inner sides of the upper die holder 1 and the lower die holder 2; the upper module 3 and the lower module 4 are respectively provided with a plurality of connecting keys 8 which are in one-to-one correspondence with the positioning grooves 6 and are clamped inside the positioning grooves 6.
