The third cavity 16 and (4) respectively connect the first cavity m cavity 16 and the first hole 200938356 flow channel 18 of the through hole 12. The first cavity 14 and the third cavity 16 are different in shape, and the two first cavity 14 lines and the two third cavity 16 are perpendicular to each other. The shape of the four first branching passages 18 can be designed as needed, and in the embodiment, they are all semi-cylindrical. The second mold core 20 has a second surface 202 and an opposite fourth surface 204. The second surface 202 faces the first mold core 10 as a parting surface. The second surface 202 is open inwardly with two oppositely shaped second cavities 24, two oppositely shaped fourth halves 26, and four second diverging channels 28. Wherein, the second cavity 24 and the fourth cavity 26 are different in shape, and the two second flow channels 28 connected to the second cavity 24 are connected to each other, and the two connection holes are opposite to the fourth cavity 26 The two split channels 28 are in communication with each other. The four second split channels 28 are also all semi-cylindrical. The second mold core 20 can also be provided with a plurality of ejector holes (not shown) for ejector pins for ejector molding products. The nozzle bushing 30 is assembled in the through hole 12 of the first mold core 10, and its outer shape is matched with the through hole 12. In the embodiment, the nozzle bushing 30 and the through hole 12 are both It is a round step shape. The nozzle bushing 30 also protrudes from the first mold core 10 and is coupled to a mold base and an injection machine (not shown). The nozzle bushing 30 includes a spout 32 and a sprue wall 34 therethrough. The surface of the nozzle wall 34 is provided with four diverting grooves 38 which are separated from the nozzle 32 inwardly. The four splitter grooves 38 are respectively connected to the four first split channels 18 of the first mold core 10, and are also all semi-cylindrical. The four splitter grooves 38 are each open inwardly with a hole 36. Each of the apertures 36 is stepped and includes a cylindrical portion of the splitter groove 38 where the connection is located and a square portion of the 200938356 which is coupled to the cylindrical portion. The diameter of the cylindrical portion of each of the cavities 36 is equal to the diameter of the diverting grooves 38. - Referring to FIG. 4 and FIG. 5 together, the two first cavities 14 and the two third die cavities 24 can be combined to form two first cavities 64, the two second cavities 16 Two second cavities 66 can be formed in combination with the two fourth cavities 26. The first cavity 64 and the second cavity 66 are different in shape and can be used to form different products. The four second split passages 28 are combined with the four first split passages 18 and the four splitter passages 38 to form four complete cylindrical flow passages 68, which are respectively connected to each other. The nozzle 32 is combined with two first cavities 64 and two second cavities 66. The two first inserts 40 respectively include a first cylindrical body 42 , a first protrusion 44 protruding from the first end of the first cylindrical body 42 , and a protrusion protruding from the first cylindrical body 42 . A second protrusion 46 at one end. The first cylindrical body 42 mates with the cylindrical portion of the aperture 36 and one of the first cylindrical bodies 42 projects partially from the aperture ❹ 36 in which it is located. The cross-sectional shape of the first protrusion 44 is the same as the cross-sectional shape of the second shunt channel 68. In this embodiment, the first protrusion 44 is hemispherical and has a radius equal to the radius of the second shunt channel 28. . The second projection 46 is square and fits into the square portion of the aperture 36. One portion of the first cylindrical body 42 and the first protrusion 44 form a stop portion that protrudes from the hole 36 and blocks the flow path 68 where it is located, thus blocking the nozzle 32 and the first one The cavity 64 or a second cavity 66 is in communication. The second projection 46 acts to prevent rotation, thereby helping to position the entire first insert 40 in the corresponding aperture 36. 11 200938356 The two second inserts 50 respectively comprise a second cylindrical body 52, a compensation groove 54 formed at the end of the second cylindrical body 52, and a protrusion protruding from the second cylindrical body 52. The second protrusion at the other end. 56. The first cylindrical body 42 mates with the cylindrical portion of the aperture 36 and is fully embedded in the aperture 36. The shape of the compensation groove 54 is the same as the shape of the opening of the hole 36 in the splitter groove 38. The second projection 56 is square and fits into the square portion of the aperture 36. The compensation groove 54 can compensate for the portion of the diverting groove 54 in the cavity 36 to communicate with the nozzle 32 and the first cavity 64 or the second cavity 66. The second projection 56 acts to prevent rotation, thereby helping to position the entire first «inlay 50 in the corresponding aperture 36. The mold apparatus 1 can be formed in accordance with the following steps: (1) selecting a desired first mold cavity 64 or a second mold cavity 66 to be ready for molding, for example, simultaneously selecting two second mold cavities 66 for preparation Forming; (2) using two first inserts 40 to be embedded in the two holes 36 of the two split grooves 38 corresponding to the two unselected first first die cavities 64 to block the nozzle 32 from the The connection of the two first cavities 64 selected by the dish, that is, the two first inserts 40 block the flow path 68; (3) embedding the selected two second modes using the two second inserts 50 The two cavities 36 of the two splitting grooves 38 corresponding to the cavity 66 communicate with the nozzle 32 and the selected two second cavities 66, that is, the two second inserts 50 compensate for the flow path 68. (4) Combining the first mold core 10 and the second mold core 20, and molding the selected two second mold cavities 66 through the nozzle 32 and the cylindrical flow passage 68 to form the injection 12 200938356. When the molding is completed, the two first inserts 40 and the two second inserts 50 can be pulled out. It can be understood that the two first cavities 64 and the two second cavities 66 in the mold device 100 can be designed to be the same, so that the four cavities can be simultaneously selected for molding. The four second inserts 50 can be used directly to compensate for the laying of the flow channels without the use of the first insert 40. Of course, when a cavity is damaged, a first insert 40 can also be used to block the flow path. The mold apparatus 100 may also have only one first mold cavity 64 and one second mold cavity 66. In addition, the stop portion of the first insert 40 is not limited to the above-mentioned one portion including the first cylindrical body 42 and the first protrusion 44, and the stop portion only needs to be connected with the flow path. 68 can be combined. The mold device 1 〇〇 utilizes the design of the nozzle bushing 30 and the use of the first β insert 40 and the second insert 50 to conveniently realize selective molding of each cavity, and increase the use of the entire mold device 100. flexibility. The first insert 40 and the second insert 50 are occluded or compensated for the flow passage 68 at the sprue bushing 30, so that the molding can be quickly flowed to the selected cavity during molding.
