Abstract
The utility model discloses a ventilating bend mould for an airplane, which comprises a mould body made of an aluminum alloy material. The mould body is composed of two detachable branch moulds (1), each branch mould (1) is provided with a plurality of first threaded holes (1.1) for screwing bolts, an embedded part (2) is tightly matched in each first threaded hole (1.1), and the center of the embedded part (2) is provided with a second threaded hole (2.1). The ventilating bend mould for the airplane enables bolt holes not to be abraded easily and avoids dumping the whole mould due to abrasion of the bolt holes.
Description
Technical field:
The utility model relates to a kind of mould, specifically is a kind of ventilation bend pipe mould of aircraft.
Background technology:
The ventilation bend pipe mould of aircraft comprises the die ontology of being processed by aluminum alloy materials, and said die ontology is made up of two removable branch moulds, and every branch mould is provided with groove, and after two branch die combination, its two grooves just in time form the inner chamber of moulding aircraft ventilation bend pipe.Adding man-hour, two branch moulds fixed, laying the carbon fiber compound material, heating and be molded into product at die ontology with a plurality of bolts, after the completion again with two branch moulds dismountings.It is not enough below the aircraft ventilation bend pipe mould of above prior art exists: because the branch mould that two aluminum alloy materials are processed is after long-term dismounting; Divide the bolt hole on the mould to wear and tear; Thereby directly influence divides the assembling of mould, finally causes whole pair of mould to be scrapped, and increases use cost greatly.
The utility model content
The technical problem that the utility model will solve is, a kind of bolt hole wearing and tearing that are difficult for making are provided, the ventilation bend pipe mould of the aircraft of avoiding scrapping because of whole pair of mould of bolt hole wearing and tearing.
The technical scheme of the utility model is; A kind of ventilation bend pipe mould with aircraft of following structure is provided; Comprise the die ontology of being processed by aluminum alloy materials, said die ontology is made up of two removable branch moulds, and every branch mould is provided with some first screwed holes that screw bolt; Close-fitting has inserts in each first screwed hole, and the center of said inserts is provided with second screwed hole.
Each inserts comprises the outer-hexagonal head and is provided with externally threaded screw rod that the said screw rod and first screwed hole are screwed.
After adopting said structure, the utility model compared with prior art has the following advantages: because close-fitting has inserts in each first screwed hole; The center of said inserts is provided with second screwed hole, like this in the long-term dismounting of minute mould, even wearing and tearing; Also only need to change inserts; Be difficult for making the bolt hole wearing and tearing of die ontology, avoid whole pair of mould to scrap, reduce use cost greatly.
Description of drawings
Accompanying drawing 1 is the sketch map of ventilation bend pipe mould of the aircraft of the utility model.
Accompanying drawing 2 is inserts schematic top plan view of ventilation bend pipe mould of the aircraft of the utility model.
Accompanying drawing 3 is inserts generalized sections of ventilation bend pipe mould of the aircraft of the utility model.
Shown in the figure, 1, divide mould, 1.1, first screwed hole, 2, inserts, 2.1, second screwed hole, 2.2, the outer-hexagonal head, 2.3, screw rod.
The specific embodiment
Be described further below in conjunction with the ventilation bend pipe mould of accompanying drawing the aircraft of the utility model.
Like Fig. 1, Fig. 2, shown in Figure 3; The ventilation bend pipe mould of the aircraft of the utility model; Comprise the die ontology of being processed by aluminum alloy materials, said die ontology is made up of two removable branch moulds 1, and every branch mould 1 is provided with some first screwed holes 1.1 that screw bolt; Close-fitting has inserts 2 in each first screwed hole 1.1, and the center of said inserts 2 is provided with second screwed hole 2.1.
Each inserts 2 comprises outer-hexagonal head 2.2 and is provided with externally threaded screw rod 2.3 that the said screw rod 2.3 and first screwed hole 1.1 are screwed.
Claims (2)
1. the ventilation bend pipe mould of an aircraft; Comprise the die ontology of processing by aluminum alloy materials; Said die ontology is made up of two removable branch moulds (1); Every branch mould (1) is provided with some first screwed holes (1.1) that screw bolt, it is characterized in that: the interior close-fitting of each first screwed hole (1.1) has inserts (2), and the center of said inserts (2) is provided with second screwed hole (2.1).
2. the ventilation bend pipe mould of aircraft according to claim 1 is characterized in that: each inserts (2) comprises outer-hexagonal head (2.2) and is provided with externally threaded screw rod (2.3) that said screw rod (2.3) is screwed with first screwed hole (1.1).
