Fig. 2 is the figure of single product structure of expression another hot flow path 20 that can use in ester moulding mould according to the present invention.Fig. 2 represents to possess the hot flow path 20 of 2 modes of 2 hot-runner nozzles 22, and what Fig. 2 (A) was illustrated in hot-runner nozzle 22 axially goes up the top view of observing, and Fig. 2 (B) expression comprises the axial side view of hot-runner nozzle 22.In addition, when using this hot flow path 20, the interval L that the hot-runner nozzle of adjacency is 22 is defined as shown in the figure.
In addition, the structure of the applied hot flow path of the present invention is not limited to Fig. 1 or structure shown in Figure 2, also can use the above hot flow paths of 3 modes such as 3 modes.And, also hot flow path for example shown in Figure 2 20 can be configured to a plurality of row shapes, 4 above hot-runner nozzles are configured in 1 row.In addition, below complicated for what prevent from illustrating, describe as representative with the situation of using hot flow path shown in Figure 2 20.
Fig. 3 is the vertical view of an example of the expression hoop material 100 that can use in ester moulding mould according to the present invention.Fig. 3 is the vertical view of observing in the face vertical direction of hoop material 100.In addition, hoop material 100 is typically by metal material and constitutes.
In addition, the structure of the hoop material that can use in ester moulding mould according to the present invention is not limited to structure shown in Figure 3, so long as have the structure of 2 above ester moulding reservations along the column direction production line of the direction vertical with hoop direction of feed production line, then can be structure arbitrarily.
At this, will be made as Lf along the interval between the ester moulding reservations of the column direction production line of hoop material 100.That is, ester moulding reservations 101,102 interval, ester moulding reservations 102,103 interval and ester moulding reservations 103,104 interval etc. are made as identical with Lf.Interval Lf between the ester moulding reservations is generally less than the interval L of 22 of above-mentioned hot-runner nozzles.This results from the progress of miniaturization of ester moulding reservations.And, result from as follows: consider from the viewpoint that improves throughput, it is favourable setting a plurality of ester moulding reservations on 1 hoop material 100 as far as possible, in contrast, (particularly carry the restriction that fasten the pass of heater) because the structural restriction of hot-runner nozzle 22, the interval L that reduces 22 of hot-runner nozzles is limited.
At this, as an example, the interval L that hot-runner nozzle is 22 is made as 4 times of interval Lf between the ester moulding reservations.Be L=4Lf.In addition, when 2 above hot-runner nozzles of 1 row (along the row of column direction production line) configuration, the interval L between hot-runner nozzle is preferably 2 times, the 3 times this integral multiples of the interval Lf between the ester moulding reservations.

Equally, hot flow path 205-208(the 2nd hot flow path group) on the direction of feed of hoop material 100 every the column direction production line of 1 hoop material 100 and dispose.That is, hot flow path 205-208 is spaced from each other the amount corresponding with 2 production lines of the column direction production line of hoop material 100 in the direction of feed of hoop material 100 and disposes.And hot flow path 205-208 goes up the amount corresponding with 1 production line of the hoop direction of feed production line of hoop material 100 of skew mutually and disposes in the direction vertical with the direction of feed of hoop material 100 (that is column direction).Namely, hot flow path 208 with the vertical direction of the direction of feed of hoop material 100 on the relatively hot runner 207 skews amount corresponding with 1 production line of the hoop direction of feed production line of hoop material 100 (the following direction in the figure) and disposing, hot flow path 207 relatively hot runners 206 similarly are offset the amount corresponding with 1 production line of hoop direction of feed production line and dispose, and hot flow path 206 relatively hot runners 205 similarly are offset the amount corresponding with 1 production line of hoop direction of feed production line and dispose.
In the example shown in Figure 4, by 2 spacings direction of feed feeding hoop material 100 shown in the P in the figure.At this, the interval in the hoop material 100 on the direction of feed of 1 spacing and hoop material 100 between the ester moulding reservations of adjacency is corresponding, and is equivalent to the amount of 2 production lines of the column direction production line of hoop material 100.That is, hoop material 100 is by the spacing feeding of the distance between the hot flow path that is equivalent to each adjacency among hot flow path 201-204 or the 205-208.
Fig. 5 is that expression is by the figure of the injection moulding flow process of hot flow path arrangement mode realization shown in Figure 4.When Fig. 5 (A)～Fig. 5 (E) represented that with the time series order position of hot flow path arrangement mode and hoop material 100 concerns, the mode of ester moulding was carried out in expression to each ester moulding reservations.Among Fig. 5 (A)～Fig. 5 (E), carried out the ester moulding reservations of ester moulding and indicated by blacking.
In Fig. 5 (A), inject thermoplastic resin simultaneously from all hot-runner nozzle 221-228 of each hot flow path 201-208, each the ester moulding reservations on the hoop material 100 that is in corresponding with hot-runner nozzle 221-228 respectively position are carried out ester moulding.
Secondly, shown in Fig. 5 (B), from 2 spacings of position feeding of the hoop material 100 shown in Fig. 5 (A).And, on the position of these 2 spacings of feeding, inject thermoplastic resin simultaneously from all hot-runner nozzle 221-228 of each hot flow path 201-208, each the ester moulding reservations on the hoop material 100 that is in corresponding with hot-runner nozzle 221-228 respectively position are carried out ester moulding.
Secondly, similarly, shown in Fig. 5 (C), from 2 spacings of position feeding of the hoop material 100 shown in Fig. 5 (B).And, on the position of these 2 spacings of feeding, inject thermoplastic resin simultaneously from all hot-runner nozzle 221-228 of each hot flow path 201-208, each the ester moulding reservations on the hoop material 100 that is in corresponding with hot-runner nozzle 221-228 respectively position are carried out ester moulding.
Below, similarly, shown in Fig. 5 (D) and Fig. 5 (E), in the time of 2 spacings of hoop material 100 feedings, all hot-runner nozzle 221-228 from each hot flow path 201-208 inject thermoplastic resin simultaneously at every turn, and each the ester moulding reservations on the hoop material 100 that is in corresponding with hot-runner nozzle 221-228 respectively position are carried out ester moulding.Like this, when hoop material 100 further is fed 2 spacings, all hot-runner nozzle 221-228 from each hot flow path 201-208 inject thermoplastic resin simultaneously at every turn, and each the ester moulding reservations on the hoop material 100 that is in corresponding with hot-runner nozzle 221-228 respectively position are carried out ester moulding.
At this, with reference to Fig. 5 (A)～Fig. 5 (E), at first, have the column direction production line P on the hoop material 100 shown in Fig. 5 (A) in mind, the ester moulding mode of each the ester moulding reservations 101-108 on the subtend column direction production line P describes.
Each ester moulding reservations 101-108 on the column direction production line P relatively each hot flow path 205-208 in 1 amount that production line is corresponding of the column direction production line of the direction of feed skew of hoop material 100 and hoop material 100.Therefore, till to the position feeding hoop material 100 shown in Fig. 5 (E), can't realize to the ester moulding of each ester moulding reservations 101-108.If at the position feeding hoop material 100 shown in Fig. 5 (E), then at first by hot flow path 204 in each ester moulding reservations 101-108 from the top the 4th and the 8th ester moulding reservations 104,108 carry out ester mouldings.Secondly, if hoop material 100 is fed 2 spacings (not shown) from the position shown in Fig. 5 (E), then by hot flow path 203 in each ester moulding reservations 101-108 from the top the 3rd and the 7th ester moulding reservations 103,107 carry out ester mouldings.Secondly, if hoop material 100 is fed 2 spacings (not shown), then by hot flow path 202 in each ester moulding reservations 101-108 from the top the 2nd and the 6th ester moulding reservations 102,106 carry out ester mouldings.Secondly, if hoop material 100 is fed 2 spacings (not shown), then by hot flow path 201 in each ester moulding reservations 101-108 from the top the 1st and the 5th ester moulding reservations 101,105 carry out ester mouldings.
Like this, the ester moulding of each the ester moulding reservations 101-108 on all column direction production line P is realized by the process by 2 spacings feeding hoop material 100 successively.
Secondly, with reference to Fig. 5 (A)～Fig. 5 (E), at first, have the column direction production line Q on the hoop material 100 shown in Fig. 5 (A) in mind, the ester moulding mode of each the ester moulding reservations 101-108 on the subtend column direction production line Q describes.
In the position shown in Fig. 5 (A), at first, by hot flow path 208 in each ester moulding reservations 101-108 from the top the 4th and the 8th ester moulding reservations 104,108 carry out ester mouldings.Secondly, if hoop material 100 is fed 2 spacings from the position shown in Fig. 5 (A) to the position shown in Fig. 5 (B), then by hot flow path 207 in each ester moulding reservations 101-108 from the top the 3rd and the 7th ester moulding reservations 103,107 carry out ester mouldings.Secondly, if hoop material 100 is fed 2 spacings from the position shown in Fig. 5 (B) to the position shown in Fig. 5 (C), then by hot flow path 206 in each ester moulding reservations 101-108 from the top the 2nd and the 6th ester moulding reservations 102,106 carry out ester mouldings.Secondly, if hoop material 100 is fed 2 spacings from the position shown in Fig. 5 (C) to the position shown in Fig. 5 (D), then by hot flow path 205 in each ester moulding reservations 101-108 from the top the 1st and the 5th ester moulding reservations 101,105 carry out ester mouldings.After, hoop material 100 is further by 2 spacing feedings, and hoop material 100 is by the below of hot flow path 201-204, but at the ester moulding that can not carry out each the ester moulding reservations 101-108 on the column direction production line Q during this period.This be because each the ester moulding reservations 101-108 on the column direction production line Q relatively each hot flow path 201-204 depart from 1 amount that production line is corresponding with the column direction production line of hoop material 100 in the direction of feed of hoop material 100.
Like this, the ester moulding of all each the ester moulding reservations 101-108 on the column direction production line Q is realized by the process by 2 spacings feeding hoop material 100 successively.
For all each ester moulding reservations 101-108 that lean on from column direction production line P on each column direction production line in downstream (right side the figure), with with any one identical mode of column direction production line P and Q, realize ester moulding by the process by 2 spacings feeding hoop material 100 successively.
In addition, the some production lines than each column direction production line of the more forward row side of column direction production line P (left side among the figure) have in the ester moulding reservations of not carrying out ester moulding by the stage of hot flow path 201.This part can only be utilized the ester moulding reservations of executed ester moulding, also can carry out the ester moulding reservations on the basis of ester moulding with additive method and utilize, and also can abandon.When the column direction production line of abandoning having in the ester moulding reservations of not carrying out ester moulding by the stage of hot flow path 201, also can begin most just not implement ester moulding to having at the column direction production line of not carrying out the ester moulding reservations of ester moulding by the stage of hot flow path 201, thereby save thermoplastic resin material.In addition, when the entire portion abandoned than the more forward row side of column direction production line P, also can begin most just this partial sterility to be executed ester moulding, thereby save thermoplastic resin material.That is, also can be only to carrying out ester moulding from column direction production line P by each column direction production line in downstream.
According to above-mentioned present embodiment, especially obtain the effect of following excellence as above.
