澆口部13時，沒有因爲澆道部17的變形而不能進行透鏡14 的定位的現象。因此’實現射出成型機41的冷卻時間的縮 短（例如，從以往的30秒縮短爲17秒），可提高透鏡14的 製造效率。 另外’在上述實施方式中，將冷卻用氣體（空氣）流 動到透過移動機構22移動的承受夹具20的搬運路徑，也可 以冷卻沿著搬運路徑移動的射出成型件12。具體地，如圖8 所示’將風道61設在承受夾具20的搬運路徑，透過供氣機 構24將冷卻用氣體向風道61内流入。由此，流入風道61内 的氣體冷卻將風道61内透過承受夾具20搬運的射出成型件 12。 而且，如圖9所示，也可在承受夾具20的嵌合槽29内 形成噴出冷卻用氣體（空氣）的喷嘴。具體地，如圖9所示， 在嵌合槽29的側面形成喷嘴71，在底座20a的外周面形成引 入從供氣機構24供給的空氣的供氣口 72。從供氣口 72引入 的氣體透過流路73引導至喷嘴71，並從喷嘴71喷出。另外， 因圖面的情況省略了定位銷27的圖示。 【圖式簡單說明】 201031517 表示用承受夾具保持射出成型件的狀態的冷卻 裝置的主視圓。 圖2是表示用承受夾具保持射出成型件的狀態的冷卻 裝置的俯視囷。 圖3是說明承受夾具的移動範圍的冷卻裝置的俯視圖。 圖4是表示保持射出成型件時的承受夾具的立體圖。

[Prior Art] A lens made of a plastic such as a camera is produced by injection molding using an injection molding machine for a mold. In the injection molding, the molten plastic material ejected from the nozzle of the injection molding machine passes through the sprue bush and the runner of the mold, and flows into the space (cavity) for molding the lens. From the viewpoint of preventing backflow or separation of the lens, the inflow port (gate) toward the cavity becomes a restricted gate having a width smaller than that of the runner. The injection-molded molded article is composed of a sprue bushing portion, a sprue portion, a gate portion, and a lens corresponding to the sprue bush, the runner, and the washing port (see, for example, Patent Document 1). After the molded product is solidified so as not to be deformed, it is taken out from the injection molding machine, and conveyed to the gate cutting device in order to cut the gate portion and separate the lens.

However, the demand for plastic lenses is increasing due to the spread of optical devices such as small cameras or portable telephones with cameras. Therefore, there is an urgent need to improve the manufacturing efficiency of plastic lenses. In order to sufficiently cool the molded article inside the injection molding machine, it takes a large amount of time (about 30 seconds). Therefore, if this time is shortened, it is expected that the manufacturing efficiency is greatly improved. However, if it is sufficiently cooled and solidified, it is emitted from the shot 3 201031517. The removal of the molding machine results in deformation of the sprue. If the sprue portion is deformed, the positioning of the lens cannot be performed when the gate portion is cut, and the lens is broken or the operation of the gate cutting device is stopped. In addition, this is not limited to lenses and is a problem that applies to all plastic products.

In the fourth aspect of the invention, the accommodating portion is a fitting groove into which the sprue portion is fitted. In the fifth aspect of the invention, the cooling jig is formed with a v-shaped groove at a portion where the sprue portion is lost between the portion and the accommodating portion. According to a sixth aspect of the invention, in the cooling jig, a flow path for guiding the gas to the v-shaped groove is formed. In the invention according to the seventh aspect of the invention, the cooling jig sandwiches the intervening portion other than the both end portions of the sprue portion between the portion and the accommodating portion, and blows the gas to the intermediate portion. In the eighth aspect of the invention, the gas is air having a temperature of 1 〇 t > c or more and 3 Å or less. Φ The method of cooling the injection molded article according to the present invention is characterized in that the injection molding machine extracts the injection molding of the product portion at the tip end of the runner portion from the injection molding machine, and sprays the cooling gas outside the injection molding machine. The invention according to the tenth aspect of the invention, characterized in that the injection molded article taken out from the injection molding machine is cooled to remove the injection molded article, includes: a step of taking out the injection molded article from the injection molding machine; a step of holding the injection molded product taken out by the injection molding machine; and blowing the gas onto the injection molding step of the injection molding held by the receiving jig. According to a tenth aspect of the invention, in the holding step, the washing portion is housed in the accommodating portion of the receiving jig, and the venting portion and the gas are sprayed to the pouring portion before the blowing step In the step of sandwiching the sprue portion between the cooling implements of the duct portion, air is blown from the cooling jig to the sprue portion in the blowing step. According to the method and apparatus for cooling an injection molded article according to the present invention, both the deformation and the injection molding taken out from the injection molding machine can be prevented, and as of 201031517, the cooling time of the injection molding in the injection molding machine can be shortened, and The manufacturing efficiency of the lens can be improved. [Embodiment] The cooling device η shown in Figs. 1, 2, and 3 has a function of transporting the injection molded product 2 to the next step in addition to the function of cooling the injection molded product 12 taken out from the injection molding machine 41. . In the present embodiment, the gate cutting step is carried out based on the gate cutting device 51. Further, in the gate cutting step by the gate cutting device 51, the mouthpiece 13 is cut and the lens (product portion) 14 is separated from the injection molding 12. The injection molding 12 is made of a transparent plastic molded by the injection molding machine 41 of the mold 41, and a cylindrical rim having a diameter larger than that of the sprue bushing portion 15 is formed in the middle of the cylindrical bead bushing portion 15. Part 16. The lens 14 is formed through the gate portion 13 at the tip end of the four runner portions 17 extending radially at a 90° pitch centering on the rim portion 16. Each of the lenses 14 has a main body portion 18, a flange portion 19 formed on the outer peripheral edge of the main body portion 18, and a gate portion 13 formed on the outer peripheral surface of the flange portion 19. In the cooling device 11 of the present invention, the injection molding material 12 in a deformable state before being sufficiently cooled and solidified is taken out from the injection molding machine 41, and is cooled outside the injection molding machine 41 to have a required state for the next step. The sufficient hardness 'is a means for efficiently cooling the injection molding 12 before cooling solidification by blowing the cooling gas (air) to the injection molding machine 12 taken out from the injection molding machine 41. The cooling device 11 has a receiving jig 20 that holds the injection molding 12 taken out from the injection molding machine 41 and conveys the held injection molding 12 to the mouthpiece cutting device $ 1 201031517; in the cooling position L2 of the cooling injection molding 12 The elevating mechanism 21 that receives the lifting and lowering of the jig 20 moves the moving mechanism 22 of the receiving jig 20 within a predetermined movable range. The receiving jig 20 is moved between the take-out position L1 of the injection molding material 12 from the injection molding machine 41, the above-described cooling position L2, and the cutting position L3 where the gate cutting device 51 is provided, by the moving mechanism 22. The moving mechanism 22 moves the receiving jig 20 to the cutting position L3 from the take-out position L1 through the cooling position L2, and conveys the injection molding 12 held by the receiving jig 20 to the pouring port cutting device 51. That is, the moving mechanism 22 constitutes a transport mechanism together with the receiving jig 20. The cooling device 11 has a cooling jig 23 that sandwiches the injection molding 12 between the receiving jig 20 and the receiving jig 20 that rises at the cooling position L2, and cools the injected injection molding 12; and supplies the cooling air to the cooling jig The air supply mechanism 24 of 23; the control unit 25 that controls the driving of each of the mechanisms 21, 22, and 24. Further, the elevating mechanism 22 may move the cooling jig 23 up and down instead of the elevating movement receiving jig 21. As shown in Figs. 1 and 4, the receiving jig 20 has a cylindrical base 20a, and a base portion 20b which is provided at a lower portion of the base 20a and has a smaller diameter than the cylindrical shape of the base 20a. The receiving jig 20 is formed with a cylindrical hole 28 from the center of the upper surface of the base 20a to the base portion 20b, four radial fitting grooves 29 and four positioning pins 27 which are 90° pitched around the hole 28. The washing portion 17 of the injection molding 12 taken out from the injection molding machine 41 is fitted to each of the fitting grooves 29. That is, the fitting groove 29 constitutes an accommodating portion that accommodates the sprue portion 17. The edge portion 30 corresponding to the opening of the upper portion of the fitting groove 29 is formed with 7 201031517 having an inclined surface. The inclined surface of the both edge portions 30 is guided and fitted to the runner portion 17 of the fitting groove 29, and the distortion in the horizontal direction of the sprue portion 17 bent when being taken out from the injection molding machine 41 is corrected. When the respective runner portions 17 of the injection molding 12 are fitted into the fitting grooves 29, the holes 28 prevent the rim portion 16 and the sprue bushing portion 15 located below from interfering with the phenomenon of receiving the jig 20. The positioning pin 27 is fitted in the positioning hole 38 formed in the cooling jig 23 (refer to 圊5), thereby positioning the receiving jig 20 with respect to the cooling jig 23. As shown in Figs. 1 and 5, the cooling jig 23 has a cylindrical base portion 23a, and a projecting portion 23b provided on the upper portion of the base portion 23a and having a diameter smaller than that of the base portion 23a. The cooling jig 23 is formed with a cylindrical hole 31 and a center 90 centered on the hole 31 from the center of the lower surface of the base portion 23a to the projection portion 23b. The four nozzles 32 that are radially inclined are four positioning holes 38 corresponding to the positioning pins 27 formed in the receiving jig 20. Further, an air supply port 36 that introduces air supplied from the air supply mechanism 24 is formed on the outer peripheral surface of the base portion 23b. The air introduced from the air supply port 36 is guided to the hole 31 and each of the nozzles 32 through the flow path 37. The air ejected from the holes 31 and the respective nozzles 32 is used to cool the injection molded article 12, and the temperature thereof is preferably 1 Torr. 〇 above and below 30 °C. In addition, since there is a problem such as dew condensation due to rapid cooling, liquid nitrogen (boiling point _丨96〇c) cannot be used instead of air. Each of the nozzles 32 is provided with a pair of flat plates 33 projecting from both ends in the longitudinal direction. The pair of flat plates 33 provided in the respective nozzles 32 constitute a flow path of the air ejected from the nozzles 32. A slope 34 is provided on the side of the flat plate 33 which is paired at the front end of each of the flat plates 33. Each of the slopes 34 forms a v-shaped groove 35 together with the slope 34 of the pair of flat plates 33. As shown in Figs. 6 and 7, the runner portion 17 of the injection molding 12 held by the receiving jig 201031517 20 is fitted to each of the v-shaped grooves 35. Further, the longitudinal length of the flat plate 33 is substantially the same as the length of the fitting groove 29' corresponding to the intermediate portion except the both end portions of the runner portion 17. The hole 31 prevents the sprue bushing portion 15 located above the rim portion 16 from interfering with the phenomenon of cooling the jig 23 when the molded piece 12 is incident between the receiving jig 20 and the receiving jig 20. Next, the processing procedure of the cooling device 所示 shown in Figs. 1 and 2 will be described. The injection molded product 12 that has been injection molded is taken out from the injection molding machine 41 through a transfer arm (not shown), and held at the take-out position L1 to withstand the loss 2 (see Fig. 4). At this time, the control unit 25 controls the moving mechanism 22 so that the receiving jig 20 is located at the take-out position L1. When the injection molding 12 is taken out from the injection molding machine 41 and is in a deformable state before being sufficiently cooled and solidified, it is prevented from being deformed by the holding and cooling by the receiving receiving jig 20 (for example, about 70 ° C or less). Become a necessary condition. When the injection molding 12 is held by the receiving jig 20, the control unit 25 controls the moving mechanism 22 to move the receiving jig 20 to the cooling position L2. When the receiving jig 20 is moved to the cooling position L2, the control unit 25 controls the elevating mechanism 21 to be held by the washing portion 17 of the receiving jig 20 of the receiving jig 20 so that the receiving jig 20 is raised to the nozzle 32 provided in the cooling jig 23. The position at which the flat plate 33 abuts (refer to FIG. 5). The sprue portion 17 is clamped by the fitting groove 29 of the receiving jig 20 and the V-shaped groove 35 of the cooling jig 23 to correct the vertical bending of the sprue portion 17 which is bent when taken out from the injection molding machine 41. When the receiving jig 20 is raised and the injection molding 12 is fixed between the receiving jig 20 and the cooling jig 23 (see Figs. 6 and 7), the control unit 25 controls the air supply mechanism 24 to eject air from the holes 31 and the nozzles 32. 9 201031517, which is ejected from the hole 31, air is blown to the sprue bushing portion 15 and the rim portion 16, and is discharged to the outside along the fitting groove 29 or the like. The sprue bushing portion 15 and the rim portion 16 are surrounded by the hole 28 formed in the receiving jig 20 and the hole 31 formed in the cooling jig 23, and the two gases that are blown through can be efficiently cooled. Further, the air ejected from the nozzles 32 is ejected to the runner portion 17 along the flow path formed between the flat plates 33, and is discharged from the gap formed on both end sides in the longitudinal direction of the flat plate 33. Further, the scrubbing portion 17 in the cooling is clamped by the fitting groove 29 of the receiving jig 20 and the V-shaped groove 35 of the cooling jig 23 to prevent the phenomenon of bending. When the injection molding 12 is sufficiently cooled and solidified, the control unit 25 controls the air supply mechanism 24 to stop the supply of air. Further, the control unit 25 controls the elevating mechanism 21 to lower the receiving jig 2〇. When the receiving jig 2 is lowered to a predetermined position, the control unit 25 controls the moving mechanism 22' to move the receiving jig 20 to the cutting position L3. When the receiving jig 20 is moved to the cutting device L3, the injection molded article 12 is taken out from the receiving jig 20 through the transfer arm (not shown). When the injection molding 12 is taken out, the control unit 25 controls the moving mechanism 22 to move the receiving jig 20 to the take-out position L1' to return the cooling device 11 to the initial state. Further, the injection molding material 12 taken out from the receiving jig 20 is fixed to the mouthpiece cutting device 51 by the conveyance arm, and the predetermined processing is performed.] The control unit 25 controls the driving of each of the mechanisms 21, 22, and 24, and outputs the same. The injection molding 12 taken out by the molding machine 41 repeats a series of processes: transportation to the cooling device 23 - cooling by the cooling jig 23 - transportation to the cleaning device 5 - the cooling device 11 returns to the initial state. By performing the series of processes in a repeated manner, it is possible to convey the injection molded article 12 to the gate cutting device 51 without deforming the 201031517 before the solidification is sufficiently solidified. As described above, the step of cutting the gate portion 13 is provided. Since the step of cooling while preventing the deformation of the molded article 12 is performed, even if the injection molding member 12 before the solidification is sufficiently cooled by the injection molding machine 41, the deformation of the injection molding member 12 (especially, the runner portion 17) can be prevented. When the gate portion 13 is cut, the phenomenon in which the lens 14 cannot be positioned due to the deformation of the runner portion 17 is not obtained. Therefore, the reduction in the cooling time of the injection molding machine 41 (for example, from the conventional 30 seconds to 17 seconds) can improve the manufacturing efficiency of the lens 14. Further, in the above embodiment, the cooling gas (air) flows to the conveyance path of the receiving jig 20 that has passed through the moving mechanism 22, and the injection molding 12 that moves along the conveyance path can be cooled. Specifically, as shown in Fig. 8, the air passage 61 is provided in the conveyance path of the receiving jig 20, and the cooling gas flows into the duct 61 through the air supply mechanism 24. Thereby, the gas that has flowed into the air passage 61 cools the injection molded product 12 that is conveyed through the receiving jig 20 in the air passage 61. Further, as shown in Fig. 9, a nozzle for discharging a cooling gas (air) may be formed in the fitting groove 29 of the receiving jig 20. Specifically, as shown in Fig. 9, a nozzle 71 is formed on the side surface of the fitting groove 29, and an air supply port 72 for introducing air supplied from the air supply mechanism 24 is formed on the outer peripheral surface of the base 20a. The gas introduced from the air supply port 72 is guided to the nozzle 71 through the flow path 73, and is ejected from the nozzle 71. In addition, the illustration of the positioning pin 27 is abbreviate|omitted by the figure.
