Abstract
The utility model relates to a kind of propellant powder molding die positioning sleeves.In view of the above-mentioned problems, the utility model is just to provide a kind of easy to use, good positioning effect, and easy to process, the propellant powder molding die positioning sleeve of working efficiency can be improved.Propellant powder molding die positioning sleeve, the stairstepping positioning sleeve including being evenly equipped with pin hole, the upper/lower terminal of pin hole are provided with chamfering.
Description
Technical field
The utility model relates to a kind of improvement of the structure of propellant powder molding die positioning sleeve.
Background technique
Mould locating sleeve is that one kind is determined during propellant powder Contoured squeeze to make mould needle be uniformly distributed to play in die hole
A kind of component of position effect, it is desirable that good positioning effect, and it is easy to use.The mould needle positioning sleeve of existing propellant powder molding die is ring
Shape is evenly distributed with the cylindrical structure of pin hole, and mold needle diameter is mounted in pin hole generally in 0.5mm or so.In propellant powder companding shaping mistake
Cheng Zhong, positioning sleeve can be squeezed out from mould needle to fall off, and after molding, to carry out plain to mould needle, and ressemble positioning sleeve.It is right
It is more difficult when 7 punch dies assemble needle guard, and 19 hole more for hole count or even 37 punch dies use difficulty
It is especially big.Because spininess mold is annular multilayer arrangement, it is difficult to that needle is penetrated positioning sleeve simultaneously when threading a needle, is brought to operation tired
Difficulty, working efficiency are low.
Summary of the invention
In view of the above-mentioned problems, the utility model is just to provide a kind of easy to use, good positioning effect, and easy to process, energy
Improve the propellant powder molding die positioning sleeve of working efficiency.
In order to achieve the above purposes, the technical solution adopted by the utility model is: propellant powder molding die positioning sleeve, including it is equal
It is furnished with the stairstepping positioning sleeve of pin hole, the upper/lower terminal of pin hole is provided with chamfering.
The ladder number of plies of positioning sleeve is layer 2-4.
Positioning sleeve material is brass or steel.
The chamfering of the upper/lower terminal of pin hole is respectively 1 × 30 °, 0.5 × 45 °.
Utility model beneficial effect
The utility model is by improving former propellant powder molding die positioning sleeve, in the constant situation in pin hole position,
Flared structure is used using ladder-type structure positioning sleeve, and at pin hole both ends, keeps the assembly manipulation of the utility model convenient, fast
Victory can be improved production efficiency.Stairstepping positioning sleeve and mold addition monomers mating surface are small, are easily worked.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of 19 punch die the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the installation diagram using the utility model.
Specific embodiment
The utility model includes the ladder for being evenly equipped with the positioning sleeve 1 in stairstepping positioning sleeve 1,7 hole to 37 punch dies of pin hole
The number of plies is 2 to 4 layers, and the upper/lower terminal of pin hole 2 is provided with chamfering, and upper end chamfer is 1 × 30 °, lower end chamfer is 0.5 ×
45°.The material of positioning sleeve 1 can require selection brass or steel according to mold.
It is with specific purpose tool that mould needle 5 is relatively straight with silk by 1 wiped clean of positioning sleeve when assembly, with fine sandpaper by mould needle 5
The burr on head is handled well, and then by mould needle 5, successively layer is penetrated in the pin hole 2 of positioning sleeve 1 from inside to outside, and positioning sleeve 1 is made to exist
In mold addition monomers 4 it is up and down freely, and positioning sleeve 1 is fixed on to the root of mould needle 5.In propellant powder extrusion process,
Spice gradually squeezes out positioning sleeve 1, and in the process, positioning sleeve 1, which can play, makes the equally distributed work in spice of mould needle 5
With the generation in the inclined hole of propellant powder and interior outer arc thickness ununiformity phenomenon caused by avoiding because of mould needle cohesion, deviation.
