Current substantially have more high stability, so as to ensure that the current concentrated can outrange, and do not have unit area hydraulic pressure mistake
The risk brought of height, but due to having entire body screw thread in its pipe, while must be integrally formed again, therefore with general in manufacture
Mould percent defective difficult to realize is low, efficiency high manufacturing effect.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of pipe fitting injection molding mold, the pipe fitting injection molding mold is by closing
The structure setting of reason, the manufacture percent defective that has been effectively ensured above-mentioned pipe fitting is low, production efficiency is high, and the pipe fitting quality for producing
Reliable, it is secure that pipe fitting projects flow stability when in use.
The present invention is achieved by the following technical programs.
A kind of pipe fitting injection molding mold that the present invention is provided, including columned core rod and the pattern being arranged on outside core rod；Institute
State and screw channel is provided with core rod；Fixed block groove is provided with the inwall of the pattern cylindrical, hollow, fixed block groove is oval half
Centrum groove；Screw channel is two, and two are oppositely arranged, and more than five times of diameters of core rod, the depth of screw channel is mould to the pitch of screw channel
Between 1st/1st/20th to 15 of core diameter；One end of core rod is fixed with screw mandrel, and the screw on screw mandrel is by fixing
Gear thereon is driven by injection machine and rotated；The pattern is two-half die, non-wall of the fixed block groove located at any half module of pattern
Along position.
The fixed block groove is multigroup, and quantity contained by every group is more than four；In every group, each fixed block groove is along the pattern
The distribution of inwall even circumferential, and each fixed block groove distance on the inner circle axis projection of pattern is zero.
On the pattern, the cross section projected position of pattern is provided with tapped through hole in fixed block groove；Every screw thread
Through hole is correspondingly arranged on screw rod.
The screw rod is two sections, and two sections of connecting point positions are just to the inner circle axis midpoint of pattern, and two sections of opposite proximal ends are solid respectively
Surely there is leading screw, the gear that the screw of leading screw passes through to be fixed thereon drives rotation by injection machine.
The cross section of the screw channel is triangle, and its edge lengths reverse with hand of spiral is and hand of spiral one side in the same direction
Where the three times of length one side to five times and in the same direction with hand of spiral between straight line and the inner circle tangent line for being tangential on the pattern
Angle is 80 °~110 °.
The beneficial effects of the present invention are：By rational structure setting, the manufacture waste product of above-mentioned pipe fitting is effectively ensured
Rate is low, production efficiency is high, and the pipe fitting reliable in quality for producing, and it is secure that pipe fitting projects flow stability when in use.

Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of pipe fitting injection molding mold as shown in Figure 1 to Figure 3, including columned core rod 2 and the type being arranged on outside core rod 2
Mould 1；Screw channel 21 is provided with the core rod 2；Fixed block groove 11 is provided with the inwall of the cylindrical, hollow of the pattern 1, it is fixed
Block groove 11 is oval hemivertebra groove；Screw channel 21 is two, and two are oppositely arranged, and the pitch of screw channel 21 is more than five times of core rods 2
Diameter, the depth of screw channel 21 is between 1st/1st/20th to 15 of the diameter of core rod 2；One end of core rod 2 is fixed with silk
Bar 22, the gear that the screw 23 on screw mandrel 22 passes through to be fixed thereon drives rotation by injection machine；The pattern 1 is two-half die, Gu
Block groove 11 is determined located at the non-wall of any half module of pattern 1 along position.
Being driven by electric motor of injection machine using above-mentioned setting, during manufacture can easily ensure that entire body screw thread can be light in pipe fitting
It is easy to get to and the pipe fitting for producing is when in use, and current can form eddy flow, so that more stable after projecting, reach distance is farther.
The specific setting of the depth and pitch of screw channel 21, then should consider pipe fitting use when flow characteristics in the case of, by a large amount of
The most suitable result obtained after test and modeling Simulation, its specific numeral should also be according to fluid density, pump pressure, inlet pipe initial velocity etc.
Depending on factor.
The fixed block groove 11 is multigroup, and quantity contained by every group is more than four；In every group, each fixed block groove 11 is along described
The inwall even circumferential distribution of pattern 1, and each fixed block groove 11 distance on the inner circle axis projection of pattern 1 is zero.
Equally distributed setting, essentially consists in mean allocation centrifugal force, so that during ensureing to fix use for a long time, no
Can because rocking of causing of eddy flow and caused by pipe fitting displacement or deform, tube burst possibility is smaller.
On the pattern 1, the cross section projected position of pattern 1 is provided with tapped through hole 12 in fixed block groove 11；Often
Bar tapped through hole 12 is correspondingly arranged on screw rod 3.
The screw rod 3 is two sections, and two sections of connecting point positions are just to the inner circle axis midpoint of pattern 1, two sections of opposite proximal end difference
Leading screw is fixed with, the gear that the screw of leading screw passes through to be fixed thereon drives rotation by injection machine.Essentially consisted in using the setting and kept away
Exempt from turnover of the turnover of screw rod 3 to core rod 2 and cause interference, simultaneously because the thread density of screw rod 3 is far above core rod 2, therefore
Manufacture efficiency can largely be improved.
The cross section of the screw channel 21 is triangle, and its edge lengths reverse with hand of spiral is in the same direction with hand of spiral one
Straight line and the inner circle tangent line for being tangential on the pattern 1 where the three times of edge lengths one side to five times and in the same direction with hand of spiral
Between angle be 80 °~110 °.The effect for ensureing pipe fitting in terms of eddy flow is caused is essentially consisted in using the setting.
The present invention is when in use：Core rod 2 is pushed, type film 1 closes, then in the insert type film 1 of screw rod 3, then noted
Modeling, first rotation pulls out screw rod 3 after shaping, then open type film 1, and then rotation pulls out core rod 2.
