Detailed description of the invention
Below, be described for implementing preferred embodiment of the present invention with reference to accompanying drawing.
Fig. 1 is the figure of the single product structure representing the hot flow path 10 that can use in resin molding mold according to the present invention.Fig. 1 represents that the hot flow path 10, Fig. 1 (A) possessing single hot-runner nozzle 12 represents the top view axially observed at hot-runner nozzle 12, and Fig. 1 (B) represents the side view comprising the axis of hot-runner nozzle 12.In addition, when this hot flow path 10 is arranged to multiple column-shaped, the interval L between the hot-runner nozzle 12 of adjacent hot flow path 10 is L=l1+l2.
Fig. 2 is the figure of the single product structure representing another hot flow path 20 that can use in resin molding mold according to the present invention.Fig. 2 represents that the hot flow path 20, Fig. 2 (A) of 2 modes possessing 2 hot-runner nozzles 22 represents the top view axially observed at hot-runner nozzle 22, and Fig. 2 (B) represents the side view comprising the axis of hot-runner nozzle 22.In addition, when using this hot flow path 20, the interval L between adjacent hot-runner nozzle 22 is defined as shown in the figure.
In addition, the structure of the hot flow path that the present invention applies is not limited to the structure shown in Fig. 1 or Fig. 2, also can use the hot flow path of more than 3 modes such as 3 modes.Further, also the hot flow path 20 such as shown in Fig. 2 can be configured to multiple column-shaped, more than 4 hot-runner nozzles are configured in 1 row.In addition, complicated in order to what prevent from illustrating below, be described for representative to use the situation of the hot flow path 20 shown in Fig. 2.
Fig. 3 is the top view of the example representing the hoop material 100 that can use in resin molding mold according to the present invention.Fig. 3 is the top view observed in the face vertical direction of hoop material 100.In addition, hoop material 100 is typically made up of metal material.
Hoop material 100 regularly sets ester moulding reservations along the hoop direction of feed production line corresponding with the direction of feed of hoop material 100 and column direction production line with chessboard trellis.In example as shown in Figure 3, column direction production line possesses 8 ester moulding reservations 101-108.
In addition, the structure of the hoop material that can use in resin molding mold according to the present invention is not limited to the structure shown in Fig. 3, as long as the column direction production line along the direction vertical with hoop direction of feed production line has the structure of more than 2 ester moulding reservations, then it can be arbitrary structure.
At this, the interval between the ester moulding reservations of the column direction production line along hoop material 100 is set to Lf.That is, the interval between the interval between ester moulding reservations 101,102, ester moulding reservations 102,103 and the interval etc. between ester moulding reservations 103,104 are set to identical with Lf.Interval Lf between ester moulding reservations is generally less than the interval L between above-mentioned hot-runner nozzle 22.This results from the progress of miniaturization of ester moulding reservations.And, result from as follows: from the viewpoint of raising throughput, it is favourable that 1 hoop material 100 sets multiple ester moulding reservations as far as possible, in contrast, due to the structural restriction (restriction that the pass of particularly carrying heater is fastened) of hot-runner nozzle 22, the interval L reduced between hot-runner nozzle 22 is limited.
At this, as an example, the interval L between hot-runner nozzle 22 is set to 4 times of the interval Lf between ester moulding reservations.I.e. L=4Lf.In addition, when 1 row (row along column direction production line) configure more than 2 hot-runner nozzles, the interval L between hot-runner nozzle is preferably 2 times, the 3 times this integral multiples of the interval Lf between ester moulding reservations.
