Therefore, in the above-described conventional product, as shown in FIG. 11B, the core is mounted on the mounting plate in a state where the entire core is exposed. The core is apt to swing due to vibrations sometimes occurring, and under such a condition, the movable side mold plate moves toward the above-mentioned mounting plate to close the mold. Therefore, when the conventional device of this kind is used, for example, at the time of mold closing, the core is not accurately and smoothly inserted into the pores, and there is an adverse effect that the ultrafine and expensive core is easily broken. However, there is a problem that the maintenance cost of the device is high because the life of the core is short and the replacement of the core requires a lot of labor and time.

Further, in the case of the conventional product, the resin is injected with the tip of the core being supported by the above-mentioned pores. Therefore, when the conventional product is used, the core is deformed by the injection pressure of the resin. However, there is a problem in that it is difficult to obtain a molded product with high accuracy.

Further, in the conventional product, since the resin is injected into the cavity prepared in advance, there is a trouble that a gap or the like for removing the cavity gas (air) must be formed in the mold. The injection pressure of the resin was also relatively high.

By the way, in the case of this type of molded product, due to its nature, it is not possible to form a draft for facilitating the die cutting. However, in the conventional device, as shown in the figure, the pins for ejecting the molded product are arranged at the places such as runners, and the runners are projected to release the molded product. When used, there is a problem that the molded product is difficult to release from the mold, and as a result, the molded product is easily damaged during the die cutting operation.

The present invention is intended to solve the problems of the conventional products. Therefore, the technical problem of the present invention is to prevent a situation in which the core is broken during the molding operation and to keep the maintenance cost of the device at a low cost, and to prevent a situation in which the core is deformed by the injection pressure of the resin, which is highly accurate. A molded product can be obtained, and the process of venting the cavity gas (air) can be omitted, and the injection pressure can be low, and further, the mold release can be facilitated and the yield can be improved. The object is to provide a molding device for the formed ferrule.

Next, the operation of this embodiment will be described. First,
When the mold is closed, the movable mold plate 4 is moved from the state shown in FIG. 2 to the mounting plate 3 side by being guided by the support pins 13. The tip of the cavity forming rod 15 abuts on the fixed-side mold plate 10, and the core support hole 15a and the insertion hole 11 are inserted.
When the two communicate with each other (see FIG. 3), the cavity forming rod 15
As described above, since is slidably fitted in the cavity 7, it is retracted until the tip of the movable side mold plate 4 is flush with the vertical surface. Therefore, the movable side mold plate 4 and the fixed side mold plate 10 are brought into close contact with each other and integrated (see FIG. 4). Next, in this state, the movable side mold plate 4 moves to the mounting plate 3 side together with the fixed side mold plate 10, and as a result, the core 1 moves according to the moving distance between the movable side mold plate 4 and the fixed side mold plate 10. , Is inserted into the core support hole 15a of the cavity forming rod 15. Then, the movable side mold plate 4 is closed by the mounting plate 3 with the fixed side mold plate 10 interposed therebetween (see FIG. 5).

When the mold closing operation is completed, the injection of resin is started via the sprue 2 (see FIG. 6). The injected resin, after flowing through the runner, pushes back the cavity forming rod 15 with its injection pressure and moves it backward (see FIG. 7). When the resin corresponding to the injection amount enters the cavity 7, the cavity forming rod 15 is completely returned (see FIG. 8). In this case, the cavity forming rod 15 has the core supporting hole 1
The core 5 is supported by 5a, and the cavity 7 is formed while moving backward.

As described above, in the device of the present invention,
The fixed-side mold plate with the core insertion hole is mounted between the fixed-side mounting plate and the movable-side mold plate with a gap from the mounting plate for the length of the core inserted into the cavity. The core is provided so that it can be moved in and out of contact with the plate, and in this case, the core has a length set such that the tip is arranged at the outlet of the insertion hole. Therefore, in the case of the present invention, the core is protected by the fixed-side template and is less susceptible to vibrations,
Moreover, since the core can be inserted in a state of being extremely close to the core supporting hole, the core can be inserted with high accuracy, and when the mold is opened, the movable side mold plate and the fixed side mold plate are in close contact with each other. Since the core can be pulled out by pulling it away from the mounting plate, it is possible to reduce vibrations and the like that occur during mold release. As a result, by using the device of the present invention, it is possible to prevent the situation where the core is broken at the time of mold closing or mold opening, so that the life of the core can be extended and the time and effort required for replacing the core can be reduced. It has an excellent effect that the maintenance cost can be reduced.

1. A fixed side mounting plate on which a core is mounted orthogonally on a side surface and a sprue, and a movable side which is formed so as to be movable toward and away from the mounting plate so that a mold closing mold opening operation is possible. A mold plate and a mold release mechanism provided on the movable mold plate and provided with pins for projecting the molded product, and the cavity into which the core is inserted at the axial center position when the mold is closed is In a ferrule molding apparatus formed on a movable side mold plate, a fixed side mold plate having a through hole for the core and a tapered through hole communicating with the sprue is formed on the mounting plate and the movable side. Formed on the movable side mold plate so that it can be moved toward and away from the mounting plate with a gap of the length of the core inserted into the cavity from the mounting plate. The cavity is formed in the shape of a through hole, Further, the above-mentioned molded product release mechanism includes a cavity forming rod in which a core supporting hole for supporting the core is formed, and the core has a length set such that a tip end thereof is arranged at an outlet portion of the insertion hole, In addition, the cavity forming rod slidably fitted in the cavity is retracted by the injection pressure of the resin while supporting the core in the core supporting hole at the time of injection,
A ferrule molding device that allows the molded product to be projected together with the above pins when released from the mold.
