Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of injection mold, is used for injection molding agitation wheel for washing machine 21, as shown in Figure 2 a, including
The cope plate 10 and lower template 40 of mutual pairing are provided with mandril group 50 and the inserts for fixing inserts 20 below lower template 40
Core 31 is inlayed, the via hole b for passing through inserts edge core 31 and mandril group 50 is provided in lower template 40, mandril group 50 and inserts inlay core
31 can move above and below relative to lower template 40, and mandril group 50 and inserts edge core 31 be when moving upwards, can washing injection molding
Clothing machine impeller ejects lower template 40.
As shown in Figure 2 a, mandril group 50 is made of multiple mandrils 501.Mandril group 50 and inserts edge core 31 can be relative under
Template 40 moves above and below, and mandril group 50 and inserts edge core 31 be when moving upwards, as shown in Figure 2 d, can be by injection molding
Agitation wheel for washing machine 21 ejects lower template 40.
It should be noted that need to be pre-machined inserts 20 in the technical process of 21 injection molding of impeller, it then will be embedding
Part 20, which is placed on to be molded again in lower template 40, enables the impeller 21 of injection molding to be structure as a whole with inserts 20.In this way
One, inserts 20 can be as the transmission parts of impeller 21, for being connected with machine shaft, so that motor passes through
Inserts 20 drives impeller 21 to rotate.During impeller 21 rotates, the stress of inserts 20 is larger, therefore inserts 20 is relative to wave
For wheel 21, need to be prepared using harder material.Preferably, constitute inserts 20 material can for hard metal or its
The harder organic material of his material.
In addition, when mandril group 50 and inserts edge core 31 are as shown in Figure 2 d, it, should when the impeller 21 of injection molding can be ejected
40 mandril group 50 of lower template and inserts edge core 31 are required to penetrate the lower template 40.And the lower template in the embodiment of the present invention
40, it as shown in Figure 2 a, can be by lower plate 401 and the impeller mold 402 opposite with 21 shape of impeller in the lower plate 401
Composition.In the case, in the present embodiment, the 40 mandril group 50 of lower template and inserts edge core 31 penetrate the lower template 40 and are
Refer to, mandril group 50 and inserts edge core 31 penetrate above-mentioned impeller mold 402.Wherein, which can pass through the side such as screw thread
Formula is installed in lower plate 401 or impeller mold 402 can be structure as a whole with lower plate 401.
It should be noted that the directional terminologies such as "up" and "down" are shown relative to the injection mold in attached drawing in the present embodiment
The orientation put anticipate to define, it should be understood that, these directional terminologies are opposite concepts, they be used for relative to retouch
It states and clarifies, can correspondingly be changed according to the variation in the orientation that injection mold is placed.
In conclusion when being moved upwards due to mandril group 50 and inserts edge core 31, it can be by the Washing machine wave of injection molding
21 ejection lower template of wheel.Therefore before being molded agitation wheel for washing machine, mandril group 50 and inserts can also be driven to inlay core 31 and transported upwards
Dynamic, mandril group 50 and inserts edge core 31 can penetrate the lower template 40 by the via hole b in lower template 40 at this time, so that inserts
It can be pierced by the lower template 40 for installing the part of inserts 20 on edge core 31, avoid being used to form impeller 21 in lower template 40
Model blocks 20 installation site of inserts, so that staff be facilitated to install inserts 20, improves inserts 20 embedding
The accuracy of contraposition is installed on part edge core 31, so that reduce causes to be installed on since impeller 21 installs inaccuracy with inserts 20
There is biggish end jump during rotation in impeller 21 on motor output shaft and diameter jumps phenomenon, thereby reduces rotary drum washing machine
The vibration generated in the running and noise, improve washing effect and product quality.
On the other hand, after completing the Shooting Technique of impeller 21, mandril group 50 and inserts edge core 31 are moved upwardly together, embedding
Part edge core 31 can provide the center of impeller 21 upward thrust, and mandril group 50 can provide upwards the periphery of impeller 21
Thrust so that completely cooling impeller 21 is not during ejecting lower template 40, whole uniform force.To avoid
There is the phenomenon that local deformation due to unbalance stress during ejecting lower template 40 in impeller 21.And then improve impeller 21
Yields.
On this basis, as shown in Figure 2 b, lifting supporting plate 60, the top installation of lifting supporting plate 60 are set below lower template 40
There are mandril group 50 and inserts edge core 31.So, mandril group 50 and inserts edge core 31 can be under the drives of lifting supporting plate 60
Upper and lower movement together, so that the movement of mandril group 50 and inserts edge core 31 is steady.
Furthermore it is preferred that, as shown in figure 3, multiple mandrils 501 are centered on inserts edge core 31, circumferentially form is distributed in
The periphery of inserts edge core 31.Specifically, being required according to the size of the impeller 21 of required injection molding, mandril group 50 can be with embedding
Part inlays in the lifting supporting plate 60 centered on core 31 circumferentially form and is arranged 2~4 weeks mandrils 501, and radius of a circle from it is interior to
Be gradually increased outside, all numbers that mandril group 50 is arranged excessively waste material, increase cost, all numbers of setting excessively it is few be then easy due to
Power unevenness leads to 21 local deformation of impeller of injection molding.
In addition, mandril 501 die sinking ejection injection molding impeller 21 when, due to impeller 21 also in be formed but also
Not completely cooling state, is locally deformed with, therefore mandril in the impeller 21 that will lead to more excessive than relatively thin position local pressure
501 usually require to be correspondingly arranged at the 21 biggish reinforcing rib of lower end thickness of impeller.
On this basis, 501 quantity of mandril on each week is 8~12, due to usually requiring to be correspondingly arranged to wave
It takes turns at the 21 biggish reinforcing ribs of lower end thickness, therefore 501 quantity of mandril on each week cannot be more than reinforcing on 21 wheel disc of impeller
The number of muscle, if it is each week on 501 quantity of mandril be more than 12, some mandrils 501 can only directly pushing tow compare in wheel disc
Thin position, due to when mandril 501 ejects impeller 21 also in incomplete cooling and shaping state, than relatively thin position part
The excessive impeller 21 that will lead to of stress is locally deformed with.In addition, if 501 quantity of mandril on each week is less than 8, mandril
501 are difficult to bear the weight of impeller 21, are easy to generate damage to mandril 501.
Further, the diameter of each mandril 501 is generally arranged between 4mm~5mm.The diameter of mandril 501 is less than 4mm
When the gravity that can carry it is too small, it is difficult to the own wt for supporting impeller 21 is easy to produce bending damage.And mandril 501 is straight
When diameter is greater than 5mm, in order to guarantee that the uniform force on 21 wheel disc of mandril 501 and impeller between reinforcing rib is stablized, it is necessary to increase
The wall thickness of reinforcing rib, and the wall thickness of reinforcing rib is excessive, is easy to cause the inside and outside cooling velocity at reinforcing rib inconsistent, thus in wave
It takes turns 21 surfaces and generates shrink mark, influence appearance and quality.
The process of 21 injection molding of impeller is described in detail below, specifically, first as shown in Figure 2 b, lifting support
Plate 60 moves upwards, and inserts edge core 31 and mandril group 50 move upwards penetrate lower template 40 therewith at this time, then that inserts 20 is right
Position is simultaneously mounted on the inserts edge core 31 of exposing.
Next, as shown in Figure 2 c, lifting supporting plate 60 moves downward, and inserts 20 is retracted into 40 bottom of lower template.So
Template 10 is closed to lower cover afterwards and in the direction of the arrow, and is molded from the injection hole a on 10 top of cope plate.
After the completion of injection molding, as shown in Figure 2 d, cope plate 10 is opened up by arrow direction, slightly to the impeller 21 of injection molding
Add cooling, lifting supporting plate 60 drives inserts edge core 31 and mandril group 50 to move upwards again, and inserts inlays core 31, and inserts 20 is upward
It releases, upward thrust is provided with the center to impeller 21.Mandril group 50 is acting upwardly on the reinforcing rib of 21 wheel disc of impeller
On, upward thrust is provided with the periphery to impeller 21, so that under entire impeller 21 ejects in the state of stress equalization
Template 40.
Next, the impeller 21 of the injection molding on inserts edge core 31 can be removed manually.
Or lifting supporting plate 60 is moved downward, since the inserts 20 to have combined as a whole at this time with impeller 21 is also fixed on
Inserts is inlayed on core 31, and lifting supporting plate 60, which moves downward, will drive impeller 21 and move downward, so that impeller 21 connects with lower template 40
During touching, automatically disengaged with inserts edge core 31.Specifically, due to the meeting after being detached from lower template 40 of impeller 21 of injection molding
It is further cooling, therefore the hardness of impeller 21 can further increase.And during cooling, the size of impeller 21 and position
Certain variation can occur, to can not fasten completely with the impeller mold 402 in lower template 40.So in 60 band of lifting supporting plate
During dynamic impeller 21 is moved downward and is in contact with impeller mold 402, impeller 21 can be detached from inserts edge core 31 automatically.
On this basis, in order to improve lifting supporting plate 60 to the fixed function of inserts edge core 31, guarantee in lifting supporting plate 60
During upper and lower movement, the inserts being mounted in lifting supporting plate 60 inlays 31 fixation of core and is not likely to produce shaking, such as Fig. 2 b
It is shown, the lower end of inserts edge core 31 is provided with lug boss 310 as shown in Figure 2 d, while being further fixed in lifting supporting plate 60
For compressing the fixed plate 70 of lug boss 310.It is logical to realize so as to be cooperated by fixed plate 70 and lug boss 310
The effect that fixed plate 70 further reinforces inserts edge core 31 is crossed, guarantees that inserts edge core 31 firmly installs, and keep at work
Stabilization is not shaken.
Likewise, guaranteeing to hold in the palm in lifting to improve lifting supporting plate 60 to the fixed function of the mandril 501 in mandril group 50
Plate 60 is above and below during movement, 501 fixation of mandril that is mounted in lifting supporting plate 60 and is not likely to produce shaking, can also
Lug boss 310 is arranged in 501 lower end of mandril.On this basis, above-mentioned fixed plate 70 can also be with 310 phase interworking of lug boss
It closes, further to reinforce by fixed plate 70 to mandril 501, guarantees that mandril 501 firmly installs, and keep stablizing not at work
It shakes.
In addition, stretched out upwards to make the mandril 501 in inserts edge core 31 and mandril group 50 that can pass through fixed plate 70,
And then impeller 21 is ejected into lower template 40, it is also required in fixed plate 70 to be machined with for passing through inserts edge core 31 and mandril group 50
Via hole b (such as Fig. 2 b), the lid of fixed plate 70 close in lifting supporting plate 60, so that inserts edge core 31 and mandril group 50 are firmly fixed
In lifting supporting plate 60.
It should be noted that can be and pass through in the lug boss 310 of inserts edge 31 lower end of core setting in the embodiment of the present invention
The threaded connection fastener on inserts edge core 31, such as nut is arranged in screw thread, is also possible to integrated molding or one additional
Or multiple fixing ends, inserts is fixed on by welding or other modes and is inlayed on core 31, such as the convex block of welding.
On this basis, it is also connected with driver 80 in lifting supporting plate 60, the driver 80 is for driving lifting supporting plate 60
Upper and lower movement.To which lifting supporting plate 60 can be made stably to move under the driving of driver 80 above and below, and then make
Mandril group 50 and inserts the edge core 31 that must be installed in lifting supporting plate 60 held stationary during upper and lower movement.
Specifically, driving lifting supporting plate 60 is upper and lower as shown in figure 4, driver 80 can be set below lifting supporting plate 60
