Problems solved by technology

[0003] In this production mode, the engines need their own supporting tooling, and the pouring cylinder space is limited by the arrangement, assembly and operation of the tooling, which cannot be effectively used, and the number of engines is small; the opening of the flower plate is limited by the opening of the engine, and the number of holes is small. The gas in the slurry is completely removed, and the pouring time is long
Pouring requires a lot of tooling preparation, assembly, disassembly, cleaning, sorting and warehousing, which consumes a lot of manpower, auxiliary materials and charging hours
The traditional production mode has been difficult to meet the objective needs of mass production of models

Embodiment 1

[0030] The utility model relates to a solid rocket motor charge cluster casting tooling, which includes a flower plate assembly, a material receiving tray, a chassis, and a cross bar.

[0031] The external multi-engine engine is fixedly installed between the material receiving tray and the chassis; the flower plate assembly is installed on the material receiving tray; mouth; the external propellant falls to the receiving tray through the flower plate assembly, and then flows into the external multi-engine engine through the feeding opening;

[0032] The flower plate assembly is provided with a plurality of through holes, the diameter of each through hole is Ф3mm~Ф5mm, and the plurality of through holes form a plurality of concentric circles; on any concentric circle, the adjacent two through holes The distance between the centers of the circles is 8 mm to 20 mm. Among two adjacent concentric circles, the distance between the through holes on the concentric circle with a larger...

Embodiment 2

[0041] A small solid rocket motor charge cluster pouring tool (that is, a solid rocket motor charge cluster casting tool), such as figure 1 As shown, the cluster-type pouring tool is provided with a chassis, a material receiving tray, and a flower plate assembly. The multi-engine engine is placed on the chassis, and the material receiving tray is installed in cooperation with the multi-engine engine and the chassis. After the material receiving tray is connected to the chassis, the multi-engine engine Concentrated bondage is formed, and the flower plate assembly is installed in conjunction with the receiving tray.

[0042] Such as figure 2 As shown, the chassis is set as a polygonal structure with convex edges according to the size of the engine. Multiple engines share one chassis. In the chassis, the outer circle of some engines is inscribed on the convex edge of the chassis, and the outer circle of some engines is tangent to the outer circle of the engine itself, forming a ...

Abstract

The invention discloses a solid rocket engine charging cluster type pouring tool and method, and belongs to the technical field of energetic material preparation and filling. The solid rocket engine charging cluster type pouring tool comprises a chassis, a material receiving disc and a pattern plate assembly, wherein a multi-engine is arranged on the chassis; the material receiving disc is matchedwith the multi-engine and the chassis; after the material receiving disc is connected with the chassis, the multi-engine is bound in a centralized mode; and the pattern plate assembly is matched withthe material receiving disc. The multi-engine is compactly arranged and positioned on the chassis one by one, and is bound in a centralized mode and integrally hoisted; the chassis and the material receiving disc are simple in structure and convenient to use; the size of the pattern plate is large, the opening of the pattern plate is not limited by the size of a single-engine, and all the corresponding spaces in the material receiving disc are covered; and the pouring time can be greatly shortened by utilizing the tool, and the slurry exhaust is more thorough. The tool is simple in structure,and the overall production efficiency of the charging line is improved; and according to the method, the operation process of the pouring process is simplified, the workload is reduced, the labor intensity is reduced, and the charging cost is saved.

Description

technical field [0001] The invention relates to a solid rocket motor charging cluster pouring tool and a method, belonging to the technical field of energetic material preparation and filling. Background technique [0002] The batch charge production of small solid rocket motors generally adopts a multi-engine vacuum pouring process in one cylinder, and multiple pouring cylinders work at the same time. Its production mode is: assemble the auxiliary tooling prepared before production with the engine and put them into the pouring cylinder, and then assemble the flower plate components, pouring cylinder head, pouring pipe, valve, hopper and other tooling. Put the propellant slurry of specified quality into the hopper, and after the vacuum degree in each pouring cylinder reaches the specified pressure value, open the valve for pouring. After pouring, the pouring hopper and valve are disassembled, cleaned and sorted, and part of the pouring equipment is disassembled, cleaned, so...
