Specific embodiment
Below against attached drawing, by the description of the embodiment, to specific embodiment of the present utility model as involved
Mutual alignment and connection relation, the effect of each section and operation principle between the shape of each component, construction, each section etc. make into
The detailed description of one step：
As shown in attached drawing 1- attached drawings 3, the utility model is a kind of evacuated die-casting process injection device, and the evacuated die-casting process is used
Injection device includes shot sleeve 1, injection plunger 2, injection rod 3, and injection rod 3 is sleeved in shot sleeve 1, and injection rod 3 is located at shot sleeve
Side installation injection plunger 2 in 1, setting is along 2 one weeks mounting grooves 4 arranged of injection plunger on the injection plunger 2, in mounting groove 4
It is set with sealing ring 5.Above structure, injection rod 3 are connect with injection plunger 2, and injection plunger 2 is sleeved in shot sleeve 1, and injection plunger 2 with
The structure there are gap is set as between shot sleeve 1, then the setting mounting groove 4, then set in mounting groove 4 again on injection plunger 2
Installation sealing ring 5 is put, in this way, when injection plunger 2 is moved relative to shot sleeve 1, sealing ring 5 can reliably be fitted in shot sleeve
1 inner wall, and injection plunger outer surface is no longer contacted with the injection inside wall of cylinder, in this way, sealing ring is actually deposited when contacting the injection inside wall of cylinder
In certain pressure, therefore, it is possible to reliably realize the sealing between injection plunger and shot sleeve, sealing effect is improved.And injection plunger and
There was only sealing ring contact between shot sleeve, in this way, contact area is small between injection plunger and the injection inside wall of cylinder, when relative movement rubs
Resistance is small, injection process is made more to stablize, overall performance significantly improves.Evacuated die-casting process described in the utility model is filled with injection
It puts, it is simple in structure, it can effectively realize that the suit of injection plunger and shot sleeve seals, be moved in injection plunger relative to shot sleeve
When, injection plunger can effectively be fitted in and penetrate cylinder, improve the sealing effect between injection plunger and the injection inside wall of cylinder, while reduce injection
The contact surface of head and the injection inside wall of cylinder reduces Mo Chali, makes injection process more stable.
When the injection rod 3 is sleeved in shot sleeve 1, the sealing ring 5 in mounting groove 4 on injection plunger 2 is arranged to
The structure being enough fitted on 1 inner wall of shot sleeve, sealing ring 5 are structure made of red copper.Above structure, injection plunger can be relative to
Shot sleeve moves, and sealing ring plays sealing function, and the material of sealing ring is red copper, since red copper is softer, with respect to cast-iron structure
Shot sleeve easily deform, can reliably adapt to shot sleeve inner wall shape, so as to well with shot sleeve coordinate, carry
High sealing effect.
3 one end end set connecting pole 6 of injection rod, 2 one end end set connecting hole of injection plunger, injection rod 2 are set
It is set to the structure that can be fixedly connected by connecting pole 6 with the connecting hole of injection plunger 2.Above structure, injection rod connect with injection plunger
It connects, can be according to injection plunger to the different demands of injection pole length, thickness, and different injection rods are replaced, injection rod naturally also may be used
To replace injection plunger, it is connect with the injection plunger of different thicknesses.
Multiple tracks is set to press the mounting groove 4 of gap arrangement on the injection plunger 2, a sealing is set in per pass mounting groove 4
Ring 5, sealing ring 5 is set as the rounded structure in section, when the sealing ring 5 is installed in mounting groove 4, outside sealing ring 5
Surface is set as protruding from the structure of mounting groove 4.The inner wall of the shot sleeve 1 is set as the rounded structure in section, injection
First 2 are set as the rounded structure in section, and injection rod 3 is set as the rounded structure in section, the section of the injection plunger 2
Diameter dimension is set greater than the structure of the diameter dimension in the section of injection rod 3.Above structure, the diameter in the section of injection plunger 2
The structure of the diameter dimension in the section more than injection rod 3 is sized to, in this way, injection plunger is pushed to enter shot sleeve in injection rod
Afterwards, since the diameter dimension of the guiding role of injection plunger and the section of injection plunger 2 is set greater than the diameter in the section of injection rod 3
Size, in this way, injection rod will not touch the injection inside wall of cylinder, there is no resistance or frictional force.
Evacuated die-casting process injection device described in the utility model, injection rod are connect with injection plunger, and injection plunger is sleeved on injection
In cylinder, there are gap between injection plunger and shot sleeve, and mounting groove is set on injection plunger, then installation is set in mounting groove
Sealing ring, in this way, when injection plunger is moved relative to shot sleeve, sealing ring is reliably fitted in the injection inside wall of cylinder, and injection plunger
Outer surface is no longer contacted with the injection inside wall of cylinder, in this way, sealing ring there are in fact certain pressure when contacting the injection inside wall of cylinder, because
This, can reliably realize the sealing between injection plunger and shot sleeve, improve sealing effect.And between injection plunger and shot sleeve only
Sealing ring contacts, in this way, contact area is small between injection plunger and the injection inside wall of cylinder, frictional resistance is small during relative movement, makes injection
Process is more stablized, and overall performance significantly improves.Evacuated die-casting process injection device described in the utility model, simple in structure, energy
Enough suits for effectively realizing injection plunger and shot sleeve seal, and when injection plunger is moved relative to shot sleeve, injection plunger can have
Cylinder is penetrated in being fitted in for effect, improves the sealing effect between injection plunger and the injection inside wall of cylinder, while is reduced in injection plunger and shot sleeve
The contact surface of wall reduces Mo Chali, makes injection process more stable.
Illustrative description is carried out to the utility model above in conjunction with attached drawing, it is clear that the utility model concrete implementation is simultaneously
Do not limited by aforesaid way, if employ the utility model methodology and technical solution carry out various improvement or
It is not improved that the design of the utility model and technical solution are directly applied into other occasions, in the protection of the utility model
In the range of.
