Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Explained below relates to accompanying drawing
Time, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.In following exemplary embodiment
Described embodiment does not represent all embodiments consistent with the present invention.On the contrary, they are only and the most appended power
The example of the apparatus and method that some aspects that described in detail in profit claim, the present invention are consistent.
Embodiments of the invention one provide a kind of injection mold, and including template group and shaping mechanism, shaping mechanism is arranged on
In template group；
As in figure 2 it is shown, shaping mechanism includes running channel 101, runner and die cavity；Die cavity includes for being molded frame-shaped product
The frame-shaped die cavity 102 of surrounding；Die cavity be internally provided with an interface channel 103, the two ends of interface channel 103 respectively with
The both sides connection that frame-shaped die cavity 102 is relative, in order to be molded the rib of frame-shaped interiors of products；
Running channel 101 is perpendicular to the extension plane of die cavity；Runner includes sprue 104 and secondary channels 105；Sprue 104 is same
Time with running channel 101 and be positioned at the frame-shaped die cavity 102 of interface channel 103 side and connect, and its one end is provided with the master of inclination
Cross runner 106；One end of secondary channels 105 is provided with the pair of inclination and crosses runner 107, the other end be positioned at interface channel
The frame-shaped die cavity 102 of 103 opposite sides connects；
Main cross runner 106 and the pair runner 107 that crosses is crossed over interface channel 103 and crosses.
By sprue 104 and secondary channels 105 is crossed runner 106 and the pair runner 107 that crosses connects by main so that
The present embodiment has only to arrange a running channel 101 once the injection mold provided can realize injection mo(u)lding, waters relative to two
For road, this structure is higher to the utilization rate of raw material, it is possible to effectively reduce the waste of raw material.
Being contrasted by the injection mold that correlation technique and the present embodiment are provided by the way of actual production, its result is as follows
Shown in table 1:
The cost deck watch of the injection mold that table 1 correlation technique and the present embodiment are provided
By table 1 it can be seen that by the improvement of disclosure embodiment, often produce 50,000 products and just can save more than 4,000 yuan,
Economic benefit is the most considerable.
In the related, due to containing two running channels, it is therefore desirable to arrange a point of running channel by raw material by injection hole runner
In two running channels, therefore the walking path of its raw material is long.In order to prevent raw material from cooling down, it needs to heat runner.And
Disclosure embodiment is owing to having only to a running channel, and raw material can directly be entered in die cavity by running channel by injection hole, road of walking
Footpath is short, therefore without heating runner, has saved cost.
Wherein, in order to enable raw material to be quickly full of whole die cavity, special envoy's sprue 104 connects two runners 108；
The both sides connection that two runners 108 are relative with the frame-shaped die cavity 102 being positioned at interface channel 103 side respectively.
So raw material just can enter frame-shaped die cavity 102 by two runners 108, converges from two lateral centres, significantly contracts
The short filling time, improve production efficiency.
Embodiments of the invention two provide another kind of injection mold, as it is shown on figure 3, its difference with embodiment one is:
Template group includes male template 201 and caster 202；
101 running channels are arranged in caster 202；Male template 201 and caster 202 matched moulds constitute runner and die cavity.
In the related, owing to needs use double teeming road, therefore its shaping mechanism is complex.Article two, need between running channel
Shunted by a point running channel, make raw material be separately flowed in two running channels by injection hole.Therefore, its template group needs to be set to
Three template dies, could take out the raw material in runner.
And the disclosure is owing to using single running channel form, there is not a point running channel, therefore corresponding template group just can use two plates
The mode of mould.Compared to three template dies, filling time and the die sinking of two template dies are shorter, it is possible to be effectively improved production efficiency.
Generally, the filling time is directly proportional to filling maximum pressure, and namely pressure is the biggest, fills required time more
Short.And the present embodiment is due to running channel and the minimizing at turning, not only the filling time is short, and the stuffing pressure required when injection is also
Can reduce accordingly, therefore, it is possible to reduce equipment loss, increase the service life, further save cost.Actual test phase
Two template dies of three template dies in the technology of pass and the present embodiment, the results are shown in Table 2:
The molding parameter contrast table of the injection mold that table 2 correlation technique and the present embodiment are provided
| Molding parameter | Filling time (s) | Fill maximum pressure (MPa) |
| The present embodiment | 0.2752 | 146.2 |
| Correlation technique | 0.2825 | 156.9 |
By table 2 it can be seen that the injection mold that the present embodiment is provided fills the maximum pressure that required time is shorter, required
The lowest.
Embodiments of the invention three provide another kind of injection mold, and as shown in Figure 4, it is with the difference of embodiment two:
Also include ejecting mechanism；
Ejecting mechanism includes push pedal 301 and plunger tip 302；Plunger tip through hole 203 it is provided with in male template 201；Plunger tip through hole
203 communicate with runner.
Push pedal 301 is positioned at the back side of male template 201；One end of plunger tip 302 is fixed with push pedal 301, and the other end is led to by plunger tip
Hole 203 is stretched in male template 201.
Injection moulded products has certain adhesive due to its raw material, and the gap between its product and die cavity is less simultaneously, because of
This product is difficult to be spontaneously decoupled die cavity.And by arranging ejecting mechanism, then can after die sinking by product by die cavity ejects,
Realize fast demoulding.
Produce time, in order to improve production efficiency, typically will not wait until product cool down completely after die sinking again, therefore product is being opened
Ability of anti-deformation during mould is the most weak, being likely to cause deformation if running into bigger External Force Acting, even becoming waste product.
And the injection mold that the present embodiment is provided is by communicating plunger tip through hole 203 with runner so that plunger tip 302 is ejecting
Time power is applied directly on the raw material in runner, be transferred to the most again on product.Accordingly even when the raw material generation shape in runner
Become, also do not interfere with product self, therefore, it is possible to improve ratio defective product, rate of reducing the number of rejects and seconds.
In order to prevent causing product only some demoulding because of unbalance stress, in turn result in product and deform upon and scrap, special
Make sprue 104 and secondary channels 105 all relative with a plunger tip through hole 203.So sprue 104 and pair when the demoulding
Raw material in runner 105 can simultaneously stress, therefore more steady during product stripping, percent defective is low.
Embodiments of the invention four also provide a kind of injection mold, as it is shown in figure 5, its difference with embodiment three is:
The length of plunger tip 302 is less than the length of plunger tip through hole 203.
If plunger tip 302 directly contacts with the raw material in runner when carrying out ejecting operation, owing to both are in orthogonal
State, therefore when runner is exerted a force by plunger tip 302, the raw material in runner is likely to self and deforms upon and tilt, this feelings
Under condition, the relative position between its with product can change, and product is applied bigger torsion, it is easy to causes product to send out
Give birth to deformation and scrap.
And the present embodiment four is by making: by the way of the length of plunger tip 302 is less than the length of plunger tip through hole 203, it is possible in injection
Time make a part of raw material flow into plunger tip through hole 203, so, when plunger tip 302 exerts a force, owing to this section stays plunger tip through hole 203
In raw material can only be along the axial-movement of plunger tip through hole 203 under the restriction of plunger tip through hole 203, and it is integrated with runner
Shaping, therefore in runner, the deformation of raw material can be limited, and then the torsion suffered by product is reduced, and improves ratio defective product.
Embodiments of the invention five provide a kind of injection mold, and as shown in Figure 6, it is with the difference of embodiment four: main
Runner 106 and the pair of the crossing runner 107 that crosses is flat-shaped runner, and is pointed to the direction of intersection by the one end away from intersection,
Its length is the most tapered with thickness.
Owing to sprue 104 and secondary channels 105 lay respectively at the both sides of interface channel 103, and by the main runner that crosses
106 runners 107 that cross with pair realize being connected, and product the most after shaping can be formed the clout part connected as one.
And owing to clout partial volume is huge, the most more with the tie point of product, and together with being interweaved with product in structure, because of
This is difficult to directly clout part be departed from product by the mode such as simply seizing, drag, and extends the production time, reduces life
Produce efficiency.
And the present embodiment five is tapered flat-shaped by main cross runner 106 and the secondary runner 107 that crosses being designed as so that be molded
After clout part can be broken off easily in the intersection of the two so that clout part is divided into two little parts, reduce
The difficulty of subsequent treatment, improves production efficiency.
Embodiments of the invention six provide a kind of injection mold, as it is shown in fig. 7, on the basis of embodiment five, in order to,
Making to be present in the main runner 106 that crosses to be more prone to be broken off with the secondary clout in runner 107 that crosses, special envoy's pair crosses runner
The end of 107 is connected with the sidewall of the end of the main runner 106 that crosses；And lead the terminal end width of the runner 106 that crosses more than pair
Cross the terminal end width of runner 107.
So when applying external force, due to position between the two and architectural difference, power is easier to focus on and is present in main friendship
Conflux 106 with the intersection of the secondary clouts crossed in runner 107, without on a large scale to other local diffusion, therefore wanting
Fracture this place use power can be less.
Embodiments of the invention seven provide a kind of injection mold, and on the basis of embodiment six, plunger tip through hole 203 is two,
One of them is relative with sprue 104, and another is relative with secondary channels 105；It is provided with one in each plunger tip through hole 203
Root plunger tip 302；
Fracture be present in main cross runner 106 with secondary cross the clout in runner 107 time, need to apply one external force, and
It is also required to during product stripping provide external force.And the present embodiment seven is right by making sprue 104 and secondary channels 105 be provided with
The plunger tip through hole 203 answered, it is possible to just the clout being present in sprue 104 and secondary channels 105 is executed simultaneously when the demoulding
Adding external force, these two bursts of power can be transferred to be present in and main cross runner 106 and pair crosses the clout in runner 107, and its
It is consistent with the force direction of power needed for the clout that fractures.Therefore, by regulating the structure of clout, just may utilize plunger tip 302
Power while the demoulding, realize fractureing of clout.
As Figure 8-9, main runner 106 is crossed and the pair runner 107 that crosses crosses in the side deviating from running channel 101；
If the direction of the import being pointed to running channel 101 by the joint of running channel 101 with sprue 103 be A to；
The axis of the main runner 106 that crosses and A to angle be α；
Pair cross runner 107 axis and A to angle be β；
The terminal end width of the main runner 106 that crosses is b with the difference of the terminal end width of the secondary runner 107 that crosses；
The end of the end of the main runner 106 that crosses and the secondary runner 107 that crosses is c in A ultimate range upwards.
Confirm through great many of experiments, when aforementioned four variable is in following scope, fracture while just may be implemented in the demoulding remaining
Material.α is 30-60 °；β is 30-45 °；B is 0.2-0.3mm；C is 1.0-2.0mm.
Operation can be simplified in this way further, improve production efficiency.
