Abstract

The invention relates to a large die sectioning structure. The large die sectioning structure comprises a module dividing a die into multiple sections along the length direction. The module comprises upper die frame end face keys, lower die frame end face keys and lug plates. The upper die frame end face keys are arranged at two ends of an upper die frame, the lower die frame end face keys are arranged in correspondence to the upper die frame end face keys, the lower die frame end face keys are arranged at the bottom end of a lower die frame, and the lug plates are L-shaped, provided with through holes and fixed on four ridges of a lower die. The large die sectioning structure is convenient for manufacturing, transporting, assembling, debugging, maintaining and overhauling of the die, multiple sections of the module are accurate in relative positions, the integral strength and bearing capacity of the die are guaranteed, and motion of the die during opening and closing is accurate.

Description

A kind of large mold segmental structure

Technical field

The present invention relates to mechanical field, particularly a kind of segmental structure for the manufacture of large mold.

Background technology

The mould that is used at present large-scale component hot pressing processing, the monolithic constructions that adopt more, die size is very large, weight is above tens tons, bring very large difficulty for processing, transportation and assembling, so that mold integral intensity and bearing capacity are limited, movement accuracy shortcoming during mould open/close, be difficult for the defective of location when going back the ubiquity assembling and positioning, bring very big inconvenience for staff's operation.

Summary of the invention

Technical problem to be solved by this invention is to overcome above-mentioned defective of the prior art, and a kind of segmental structure of making large-scale hot pressing die is provided, and makes large mold can resolve into size and the less module of weight, makes easily, transports and install.

The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of.Comprise the module that mould is divided into multistage along its length, described module comprises top mold frame straight end-face key, lower mold holder straight end-face key and otic placode, described top mold frame straight end-face key is arranged at the two ends of top mold frame, the corresponding setting with the top mold frame straight end-face key of described lower mold holder straight end-face key, described lower mold holder straight end-face key are arranged at the bottom of lower mold holder, described otic placode is to have through hole on L-type, the otic placode, and described otic placode is fixed on four ribs of counterdie.

The invention has the beneficial effects as follows:

1, mould is divided into the multistage module along its length after, each root module weight is no more than 20 tons, has made things convenient for manufacturing, transportation, assembling and setting and the maintenance of mould;

2, the two ends of each root module upper and lower mould all have keyway, and straight end-face key is installed, and the mutual alignment is accurate when guaranteeing each root module connection.

3, each root module is connected by a plurality of high-strength bolts by otic placode, guarantees mold integral intensity and bearing capacity;

4, four guide plates between every root module upper and lower mould, motion accurately when guaranteeing mould open/close.

The present invention also comprises following further technical scheme.

Further, described module also comprises the guide plate that is arranged at the module both sides, and the upper end of described guide plate is fixed on the top mold frame upper and lower end and is fixed on the counterdie.

Description of drawings

Fig. 1 is single hop modular structure figure;

Fig. 2 is that two root modules connect front view;

Fig. 3 is that two root modules connect left view;

Fig. 4 is that two root modules connect top view;

Fig. 5 is five root module connection diagrams.

In the accompanying drawing, the list of parts of each label representative is as follows:

1, top mold frame straight end-face key, 2, patrix, 3, the counterdie straight end-face key, 4, otic placode, 5, counterdie, 6, guide plate, 7, top mold frame.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not be used to limiting scope of the present invention.

Fig. 1 is single hop modular structure figure, as shown in Figure 1, keyway is all offered at the patrix 2 of described module and counterdie 5 two ends, be used for installing straight end-face key, described module also comprises: the top mold frame straight end-face key 1 that is arranged at top mold frame 7 two ends, the lower mold holder straight end-face key 3 that is arranged at counterdie 5 bottoms of corresponding setting with described top mold frame straight end-face key is fixed in the L-type otic placode 4 that has through hole on 5 four ribs of counterdie and is arranged at described module both sides, upper end and is fixed in top mold frame 7 upper and lower sides and is fixed in guide plate 6 on the counterdie 5.

The total segments of mould is decided according to overall length and the factors such as processing, Lifting Capacity of workpiece, generally is divided into 2～5 root modules, and each root module length can be identical or not identical according to demand.Shown in Fig. 2 to 5, the location that top mold frame straight end-face key 1 and lower mold holder straight end-face key 3 are used between each root module, guide plate leads when being used for patrix 2 and counterdie 5 folding, have through hole on the otic placode 4, when each root module assembling, each root module is by otic placode 4 fixing link together of high-strength bolt with each root module.

The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.

Claims
