Definitions
- the present invention relates to an improvement in an injection molding machine, and more particularly to an improvement in a pre-bra type injection molding machine suitable for rubber injection molding.
- Examples of the pre-bra type injection molding machine include the one shown in FIG. This comprises an extruder 3 having a screw 2 and a plasticizing and metering function in a metal case 1, an injection port 6 connected to the extruder 3 by a passage 5 having a check valve 4, and A plunger 7 that slides in the injection port 6, a portion serving as an injection passage at the tip of the port 6 (hereinafter referred to as an injection port tip portion) 8, and an injection mounted on the tip of the injection port tip portion 8.
- the metal case 1 is supported by the upper die 11 of the mold 10 near the lower end of the metal case 1.
- Numeral 12 denotes a lower die plate connected to the upper die plate 11 by a tie bar 13
- 14 denotes a heat insulating plate
- 15 denotes a lower die also serving as a hot plate.
- the raw rubber is put into the extruder 3 as shown by the arrow in FIG. 14, and is plasticized while being sent to the left in FIG. 14 by the screw 2.
- the plasticized rubber is fed into the injection port 6 through the check valve 4 through the passage 5 and the plunger 7 is raised by the input pressure of the plasticized rubber.
- the plunger 7 is pushed down, and the plasticized rubber in the injection pot 6 is fed into the mold 10 through the injection port tip portion 8 and the injection nozzle 9, and the sprue 16 and the runner 17 are delivered.
- the gold through the gate 18 It is pressed into the cavities 19 and 20 in the mold 10 and vulcanized.
- the extruded material is metered and plasticized in the extruder as shown in Fig. 14.
- the one that is fed into the pot 6 from the side of the extruder 3 is convenient because the rubber temperature after heat generated by plasticization in the extruder 3 and the heat retention temperature in the injection pot 6 can be managed separately. .
- the screw extruder is built in the plunger.
- the temperature set in the extruder affects each other, and it is difficult to control both temperatures separately.
- the diameter of the nozzle is reduced in order to reduce the vulcanization time by introducing the molding material from the extruder into the nozzle orifice at the tip of the injection pot. If the injection heat is used with a small size, it takes a lot of time to put the molding material into the injection pot.
- the generation of the scorched rubber is more likely to occur when the rubber adhered to the inner wall surface of the injection pot 6 or the like remains in the place for a long time.
- the number of injections required to minimize the It is good to shorten the residence time. In other words, it is desirable that the rubber at the remaining portion be completely injected with the least possible number of injections and switch to a new plasticized rubber.
- the tip 8 of the injection pot has its entire length! : Since the flow velocity of the plasticized rubber at the time of injection is extremely small on the inner wall compared to its center, the plasticized rubber tends to remain in the form of cholesterol when the injection is completed. In order to remove the residual rubber from the injection port tip portion 8 in preparation for switching to a new plasticized rubber, it is necessary to repeat the injection a number of times (at least six times).
- the tip of the injection port is gradually reduced toward the nozzle, and the axis of the injection port is changed.
- the inclination angle of the inner wall surface of the tip of the injection port with respect to the axis is 0.2 ° or less in the section including the tip.
- the flow velocity distribution of the plasticized rubber at the time of injection is changed to change the tip of the injection port.
- the present inventor has previously made the invention according to Japanese Patent Application No. 2001-123771. That is, the present invention has as its main object to reduce the number of times of injection as much as possible while effectively removing the residual rubber without cleaning or disassembling the machine.
- An injection port provided with an injection nozzle and an injection port for supplying a plasticized molding material into the port are formed, and a plunger is slidably disposed in the injection port.
- the tip of the plunger is formed so as to fill at least the tip of the injection pot when the molding material is injected.
- the tip end 22 of the ejection port of the metal case 21 is formed into a tapered cross section directly from the lower end of the ejection port 24 main body.
- the inner surface of the injection nozzle 23 is also a tapered inner wall 23 a continuous with the tip portion 22 of the injection port, and the tip 27 of the plunger 26 is set at the tip portion of the injection port. 22 and formed according to the shape of the inner wall 23a of the injection nozzle 23.
- the taper angle 0 depends on the diameter of the injection port 24 determined by the size of the injection molding machine, the thickness of the upper plate 11 and the position of the extruder 3 attached to the metal case 21. In the example shown in the figure, the taper angle ⁇ was set to 30 degrees.
- the plasticized rubber injected into the injection port 25 through the extruder 3 through the passage 5 flows into the injection port 24 when the plunger 26 descends. Is pressed into the cavities 19 and 20 in the mold 10 through the injection nozzle 23 and vulcanized, but after the plunger 26 has been lowered by a predetermined amount, the tip 27 of the plunger 26 has an injection port.
- the rubber enters the tip portion 22 and descends while continuously pushing out the rubber from the injection nozzle 23.
- the flow velocity on the wall surface is large, and the rubber on the wall surface flows down without any interruption.
- the tip portion 22 of the injection pot forms a tapered portion, the connecting point K between the tip portion 22 of the injection port and the injection port 24 becomes closer to a straight line and becomes an obtuse angle. And the risk of scorching is reduced.
- the boundary between the injection port main portion and the tip portion is required. It is important that the boundary between the plunger main body and the front end portion closely adheres to the (the K-point pot diameter reducing portion) to form a close contact portion that pushes the molding material in the plasticized state. If such a contact portion can be formed, the tip 27 of the plunger 26 is completely fitted into the tip portion 22 of the injection port, and the tip 27 a is brought into contact with the inner wall 23 a of the injection nozzle 23. At least, the tip of the injection pot 22 and the inner wall 23 of the injection nozzle 23 It has been found that even if there is a gap between them as described later, the rubber can be sufficiently prevented from remaining.
- the inventor facilitates the rise of the plunger 26 by providing this gap, and also allows the plunger 26 to be moved only by supplying the molding material from the inlet 7 for supplying the molding material formed in the metal case 1. They also found it possible to rise.
- the “switching property” of the passage c between the injection port a and the nozzle b in FIG. 5 is closely related to the angle ⁇ of the passage (see FIG. 6). For example, when the angle ⁇ is 3 °, the number of injections required for switching is 10 times, but when the angle 0 is 10 °, it is 3 times, and when the angle is 60 °, it is 1 time. A cholesterol-like scorch can be prevented from occurring in 10 minutes if it is 10 ° or more.
- the tip angle of the injection port is ideally 10 ° to 40 °.
- thermal management can be performed reliably, plasticizing rubber can be reliably pressed and released in the injection port, and injection can be performed in a very precise manner.
- the number of injections can be reduced as much as possible while removing residual rubber in the injection port.
- the purpose of the present invention is to provide an injection molding machine capable of effectively performing the injection molding.
- Another object of the present invention is to provide an injection molding machine that can easily raise a plunger, has good production efficiency, and is excellent in strength. Disclosure of the invention
