Detailed description of the invention
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of high-pressure spray pipe fitting injection molding mold as shown in Figure 1 to Figure 3, the pattern 1 comprising columned core rod 2 and be arranged on outside core rod 2; Described core rod 2 is provided with screw channel 21; The inwall of described pattern 1 cylindrical, hollow is provided with fixed block groove 11, and 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 greater than the diameter of five times of core rods 2, the degree of depth of screw channel 21 be core rod 2 diameter 10 to ten/20th 1/5th between; One end of core rod 2 is fixed with screw mandrel 22, and the screw 23 on screw mandrel 22 drives rotation by the gear be fixed thereon by injection machine; Described pattern 1 is two-half die, and the non-wall of any half module of fixed block groove 11 and pattern 1 is along position.
Adopt above-mentioned setting, driven by electric motor of injection machine during manufacture and easily can ensure that in pipe fitting, entire body screw thread can obtain easily, and the pipe fitting produced in use, current can form eddy flow, thus more stable after injection, and reach distance is farther.The degree of depth of screw channel 21 and the concrete setting of pitch, then should when consider pipe fitting use time flow characteristics, through the most suitable result of testing in a large number and obtain after modeling Simulation, its concrete numeral also should be determined according to factors such as fluid density, pump pressure, inlet pipe initial velocity.
Described fixed block groove 11 is many groups, and often the contained quantity of group is more than four; Often in group, each fixed block groove 11 distributes along the inwall even circumferential of described pattern 1, and each fixed block groove 11 distance on the inner circle axis projection of pattern 1 is zero.
Equally distributed setting, is mainly mean allocation centrifugal force, thus ensures in the long-term fixing process used, and pipe fitting will be caused to be shifted or distortion because of rocking of causing of eddy flow, tube burst possibility is less.
On described pattern 1, in fixed block groove 11, the cross section projected position of pattern 1 is provided with tapped through hole 12; Every bar tapped through hole 12 correspondence is provided with screw rod 3.
Described screw rod 3 is two sections, and two sections of connecting point positions are just to the inner circle axis mid point of pattern 1, and two sections of opposite proximal end are fixed with leading screw respectively, and the screw of leading screw drives rotation by the gear be fixed thereon by injection machine.Adopt this to arrange and be mainly to avoid the turnover of the turnover of screw rod 3 to core rod 2 to cause interference, simultaneously because the thread density of screw rod 3 is far above core rod 2, therefore also can improve manufacture efficiency to a great extent.
The cross section of described screw channel 21 is triangle, itself and the reverse edge lengths of hand of spiral are three times to five times with a hand of spiral edge lengths in the same way, and and between hand of spiral place straight line in the same way and the inner circle tangent line being tangential on described pattern 1 angle be 80 ° ~ 110 °.Adopt this to arrange and be mainly to ensure that pipe fitting is causing the effect in eddy flow.
The utility model is in use: pushed by core rod 2, type film 1 closes, and then in screw rod 3 insert type film 1, carries out injection moulding subsequently, shapingly first rotates pull-out screw rod 3, then open type film 1 afterwards, rotates pull-out core rod 2 subsequently.
