The present invention relates to a method and apparatus for forming a tube head for mass production so as to facilitate production.

In general, a molding apparatus for forming a tube head is a tube (T) which is sequentially supplied by a pusher operated by a cylinder as a reciprocating member to several stored tubes as the tube supply unit 110 as shown in Figure 10a and 10b. The head mold 132 connected to the core 122 of the rotating means 120 having a 90 ° interval and then rotated at a predetermined interval, and inserted into the core and connected to the injection molding machine 130 is in contact with the core. The molding operation is performed to integrally mold the head through a predetermined cooling time at one end of the tube by the molten resin supplied to the head mold while being reciprocated as much as possible.

As such, when the head is integrally formed through the cooling time with one end of the tube, the head mold is separated from the core again and at the same time, the core is rotated at a predetermined interval by the rotating means, and the head formed on the tube inserted into the rotated core is After passing through the discharge port cut formed in the discharge portion and the lead sealing process for fusing the silver foil to the cut discharge port is discharged from the core by a discharge means such as a normal air chuck, which is required at one end of the tube The molding work in which the head is integrally formed is completed.

The conventional tube head forming apparatus as described above has the advantage of shortening the working time and increasing productivity as the head forming and the head cutting and the lead sealing and the discharge of the head are made automatically.

However, in the conventional tube head forming apparatus, the molten resin extruded from the extruder is injected into the head mold after the head mold contacts the end of the tube inserted into the core in the process of forming the head at one end of the tube. Due to the cooling time, the cooling delay time of about 20-30 seconds during the time, mass production is difficult in a short time due to the cooling delay time.

In other words, due to the condition that the tube is inserted into the core to have a cooling delay time of about 20 to 30 seconds per head, the head molding operation is not performed continuously but instead of forming the head by the cooling delay time. As the continuous delay time occurs in the process, the overall molding operation time due to the molding of the tube head is delayed, so that mass production cannot be achieved within a short time.

As it is circulated in the cooling circuit formed with the shoulder and the core will have a condition that can be cooled more quickly.

In addition, an air chamber 85 is formed above the upper cooling chamber of the rotary shaft 15, and an air spraying hole 86 is formed in the core 32 of the core transfer member 30 to be supplied from the air chamber. By connecting an air tube (not shown) so that the air to be discharged is discharged, a conventional drawing means (not shown) is carried out by an air chuck, in which the above-mentioned head is formed and the tube inserted into the core lowered horizontally by the horizontal lowering part is inserted into the core. As the air is injected through the air injection hole when the extraction is carried out, it will also have a condition that the tube can be removed more smoothly from the core together with the extraction means.

As described above, the present invention allows continuous molding operation while simultaneously rotating the head mold without cooling delay time when the head is molded at one end of the tube, thereby allowing mass production of the tube in which the head is integrally formed in a short time. It will have an effect that can be made smoothly.
