Detailed description of the invention
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the present invention.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present invention are consistent.
Embodiments of the invention one provide a kind of injection mold, comprise template group and shaping mechanism, and shaping mechanism is arranged in template group;
As shown in Figure 2, shaping mechanism comprises running channel 101, runner and die cavity; Die cavity comprises the frame-shaped die cavity 102 of the surrounding for shaping frame-shaped product; The inside of die cavity is provided with an interface channel 103, and the both sides that the two ends of interface channel 103 are relative with frame-shaped die cavity 102 are respectively communicated with, in order to the rib of shaping frame-shaped interiors of products;
Running channel 101 is perpendicular to the extension plane of die cavity; Runner comprises sprue 104 and secondary channels 105; Sprue 104 is communicated with running channel 101 and the frame-shaped die cavity 102 that is positioned at interface channel 103 side simultaneously, the runner 106 and master that its one end is provided with inclination crosses; The pair that one end of secondary channels 105 is provided with inclination crosses runner 107, and the other end is communicated with the frame-shaped die cavity 102 being positioned at interface channel 103 opposite side;
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 are communicated with by main cross runner 106 and the pair runner 107 that crosses, make the present embodiment, once provided injection mold, only needing, a running channel 101 is set and can realize injection mo(u)lding, for two running channels, the utilization rate of this structure to raw material is higher, effectively can reduce the waste of raw material.
Contrasted by the injection mold that correlation technique and the present embodiment provide by the mode of actual production, its result is as shown in table 1 below:
The cost deck watch of the injection mold that table 1 correlation technique and the present embodiment provide
Can be found out by table 1, by the improvement of disclosure embodiment, often produce 50,000 products and just can save more than 4,000 yuan, economic benefit is very considerable.
In the related, owing to containing two running channels, therefore need to arrange a point of running channel by raw material by injection hole runner two running channels, therefore the walking path of its raw material is long.In order to prevent raw material from cooling, it needs to heat runner.And disclosure embodiment is owing to only needing a running channel, raw material can directly enter in die cavity by running channel by injection hole, and walking path is short, therefore without the need to heating runner, has saved cost.
Wherein, in order to enable raw material be full of whole die cavity fast, special envoy's sprue 104 connects two runners 108; The both sides that two runners 108 are relative with the frame-shaped die cavity 102 being positioned at interface channel 103 side are respectively communicated with.
Such raw material just can enter frame-shaped die cavity 102 by two runners 108, converges, greatly shorten the filling time, enhance productivity in the middle of two side direction.
Embodiments of the invention two provide another kind of injection mold, and as shown in Figure 3, the difference of itself and embodiment one is: template group comprises male template 201 and caster 202;
101 running channels are arranged in caster 202; Male template 201 and caster 202 matched moulds form runner and die cavity.
In the related, because needs adopt double teeming road, therefore its shaping mechanism is comparatively complicated.Article two, need between running channel to be shunted by a point running channel, raw material is flowed in two running channels respectively 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 single running channel form due to what adopt, there is not runner, therefore corresponding template group just can adopt the mode of two template dies.Compared to three template dies, filling time and the die sinking of two template dies are shorter, can effectively enhance productivity.
Generally, the filling time is directly proportional to filling maximum pressure, and namely pressure is larger, and filling required time is shorter.And the present embodiment is due to the minimizing at running channel and turning, not only the filling time is short, and the stuffing pressure required when injection moulding also can correspondingly reduce, therefore, it is possible to reduce equipment loss, increases the service life, further saves cost.Three template dies in actual test correlation technique and two template dies of 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 provide
| Molding parameter | Filling time (s) | Fill maximum pressure (MPa) |
| The present embodiment | 0.2752 | 146.2 |
| Correlation technique | 0.2825 | 156.9 |
Can be found out by table 2, it is shorter that the injection mold that the present embodiment provides fills required time, and required maximum pressure is also lower.
Embodiments of the invention three provide another kind of injection mold, and as shown in Figure 4, the difference of itself and embodiment two is: also comprise ejecting mechanism;
Ejecting mechanism comprises push pedal 301 and plunger tip 302; Male template 201 is provided with plunger tip through hole 203; Plunger tip through hole 203 communicates with runner.
Push pedal 301 is positioned at the back side of male template 201; One end and the push pedal 301 of plunger tip 302 are fixed, and the other end is stretched in male template 201 by plunger tip through hole 203.
Injection moulded products has certain adhesive due to its raw material, and the gap simultaneously between its product and die cavity is less, and therefore product is difficult to depart from die cavity voluntarily.And by arranging ejecting mechanism, then can after die sinking by product by ejecting in die cavity, realize fast demoulding.
Produce time, in order to enhance productivity, generally can not wait until product cool completely after die sinking again, therefore the ability of anti-deformation of product when die sinking is also more weak, if run into larger External Force Acting probably cause deformation, even becomes waste product.
And the injection mold that the present embodiment provides is by communicating plunger tip through hole 203 with runner, on the raw material that power is applied directly to when ejecting in runner by plunger tip 302, be passed to again afterwards on product.Even if the raw material generation deformation like this in runner, also can not have influence on 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, and then cause product generation deformation and scrap, special envoy's sprue 104 and secondary channels 105 are all relative with a plunger tip through hole 203.When the demoulding, sprue 104 can be simultaneously stressed with the raw material in secondary channels 105 like this, and therefore more steady during product stripping, percent defective is low.
Embodiments of the invention four also provide a kind of injection mold, and as shown in Figure 5, the difference of itself and embodiment three is: the length of plunger tip 302 is less than the length of plunger tip through hole 203.
If the contact raw of plunger tip 302 when carrying out ejecting operation directly and in runner, because both are in orthogonal state, therefore when plunger tip 302 pairs of runner forces, probably self there is deformation and tilt in the raw material in runner, in this case the relative position between itself and product can change, and larger torsion is applied to product, be easy to cause product generation deformation and scrap.
And the present embodiment four is by making: the length of plunger tip 302 is less than the mode of the length of plunger tip through hole 203, a part of raw material can be made plunger tip through hole 203 is flowed into when injection moulding, like this, when plunger tip 302 exerts a force, staying raw material in plunger tip through hole 203 due to this section can only along the axial-movement of plunger tip through hole 203 under the restriction of plunger tip through hole 203, and itself and runner are formed in one, and therefore in runner, the deformation of raw material can be limited, and then the torsion suffered by product is reduced, improve ratio defective product.
Embodiments of the invention five provide a kind of injection mold, as shown in Figure 6, the difference of itself and embodiment four is: main cross runner 106 and the pair runner 107 that crosses is flat-shaped runner, and points to direction, its length and the equal convergent of thickness of intersection by the one end away from intersection.
Because sprue 104 and secondary channels 105 lay respectively at the both sides of interface channel 103, and realize being connected by main cross runner 106 and the pair runner 107 that crosses, therefore product after shaping can form the clout part connected as one.And due to clout partial volume huge, also more with the tie point of product, and together with structure is interweaved with product, being therefore difficult to directly clout part and product be departed from by the mode such as simply seizing, drag, extending the production time, reducing production efficiency.
And the present embodiment five-way is crossed the main runner 106 that crosses is designed to the flat-shaped of convergent with the secondary runner 107 that crosses, make shaping after clout part can be fractureed easily in the intersection of the two, thus make clout part be divided into two little parts, reduce the difficulty of subsequent treatment, improve production efficiency.
Embodiments of the invention six provide a kind of injection mold, as shown in Figure 7, on the basis of embodiment five, in order to, make to be present in the main runner 106 that crosses to be more prone to be fractureed with the secondary clout crossed in runner 107, the end of the secondary runner 107 that crosses of special envoy is connected with the sidewall of the end of the main runner 106 that crosses; And the terminal end width of the main runner 106 that crosses is greater than pair crosses the terminal end width of runner 107.
Like this when applying external force, due to position between the two and architectural difference, power more easily focuses on the intersection being present in main cross runner 106 and the secondary clout in runner 107 that crosses, and can not on a large scale to other local diffusion, and the power that this place that therefore will fracture uses 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, and one of them is relative with sprue 104, and another is relative with secondary channels 105; A plunger tip 302 is provided with in each plunger tip through hole 203;
Fracture be present in the main runner 106 that crosses with the secondary clout crossed in runner 107 time, need to apply one external force, and also need during product stripping to provide external force.And the present embodiment seven is provided with corresponding plunger tip through hole 203 by making sprue 104 and secondary channels 105, just can apply external force to the clout be present in sprue 104 and secondary channels 105 when the demoulding simultaneously, these two bursts of power can be passed to the clout being present in main cross runner 106 and pair and crossing in runner 107, and it is consistent with the force direction of power needed for clout that fractures.Therefore, by regulating the structure of clout, just can utilize the power of plunger tip 302 while the demoulding, realize fractureing of clout.
As Figure 8-9, main cross runner 106 and the pair side that runner 107 is deviating from running channel 101 that crosses crosses;
If the direction pointing to the import of running channel 101 by running channel 101 and the joint of sprue 103 be A to;
The axis of the main runner 106 that crosses and A to angle be α;
Pair cross the axis of runner 107 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 main runner 106 that crosses is c with the end of the secondary runner 107 that crosses in A ultimate range upwards.
Confirm through great many of experiments, when above-mentioned four variablees are in following scope, just can realize fractureing clout while the demoulding.α is 30-60 °; β is 30-45 °; B is 0.2-0.3mm; C is 1.0-2.0mm.
Operation can be simplified further in this way, enhance productivity.
Embodiments of the invention eight provide a kind of injection mold, as shown in Figure 10, are provided with two sleeve forming mechanisms in template group; The running channel 101 of two sleeve forming mechanisms is connected by a point of running channel 109.
The present embodiment forms the two cave of a mould by arranging two sleeve forming mechanisms in a template group, can two products of injection mo(u)lding simultaneously, significantly improves production efficiency.
