Description

[Detailed description of the invention] <Technical field to which the invention pertains> This invention is designed to prevent purged resin material (hereinafter simply referred to as purged resin) from scattering around the machine body during purging when changing materials or colors in an injection molding machine. This invention relates to an automatic purging receiving device that prevents purging from accumulating inside the machine.

<Prior art and its problems> As shown in Fig. 5, in the conventional purging process, the purge resin is processed on an extended line connecting the resin material injection nozzle 1 and the material injection port 3 communicating with the mold cavity 2. The purge receiver 4 is protruded almost perpendicularly to the extension line, and a receiver box 6 for receiving the purge resin 5 is provided below the purge receiver 4, and when a certain amount of the purge resin 5 accumulates in the receiver box 6, the operator can move to another place. It was being transported to.

In addition, the purge resin scattered around the aircraft body is currently disposed of by operators each time.

With the recent automation of machinery and equipment, traditional manual work is not only inconvenient, but also the purge receiver and receiver box repeatedly come into contact with high-temperature molten material, resulting in high temperatures, and purge resin adheres to the purge receiver and receiver box. However, it also has the disadvantage that it is impossible to discharge or remove it.

<Purpose of the present invention> The purpose of the present invention is to eliminate the above-mentioned drawbacks, prevent the purge resin from scattering, save labor, and provide an automatic purging receiving device that can perform purging automatically. .

<Summary of the present invention> In order to achieve the above-mentioned purpose, during purging, a purge plate is provided to block the material injection port and the injection nozzle communicating with the mold cavity in an extended line, and a purge plate is provided to surround the periphery of the purge plate. a purge receiver for receiving purge resin; a swash plate forming a part of the purge receiver for changing the direction of the purged resin material and discharging the purged resin material in a direction away from the center of the machine; Facing the purge board,
A purge receiver includes a scattering prevention plate that cooperates with the purge receiver to form a box to prevent the purge resin from scattering; one end is fixed to the purge receiver, and the other end is connected to a piston rod such as a cylinder. The automatic parsing receiving device is formed by arms that are movably connected and whose intermediate portions are swingably supported.

In addition, the automatic purge receiver is equipped with a nozzle for blowing out the purge resin such as air inside the box of the purge receiver to the outside of the aircraft and cooling the purge receiver.

<Embodiment> Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3. Reference numeral 11 denotes a fixed die plate to which a fixed mold 13 having a cavity 12 is attached. Reference numeral 14 denotes an injection device which injects material from an injection nozzle 15 at its tip. Reference numeral 16 denotes a purge receiving device and a material injection port 1 communicating with the cavity 12.
7 and the injection nozzle 15; a purge receiver 19 provided to surround the purge plate 18 and receiving the purge resin;
Purge receiver 1 that receives purge resin and discharges it to the outside of the aircraft
a swash plate 20 forming a part of the purge plate 1;
8 and is formed by a scattering prevention plate 21 that cooperates with the purge receiver 19 to form a box-like body to prevent the purge resin from scattering. 22 is an arm whose one end is fixed to the purge receiving device 16, and the other end is a bracket 2 fixed to the fixed die plate 11.
The air cylinder 23 is swingably supported by the air cylinder 23.
It is rotatably connected to a piston rod 26, and its intermediate portion is swingably supported by a bracket 24 fixed to the stationary die plate 11.

<Effects> Since the structure is as explained above,
During purging, when air is applied to the air cylinder 23 as shown in Figure 3, the piston rod 26
moves forward, and the other end of the arm 22 is pushed upward in the figure, so that the purge receiving device 16 at the one end blocks the extension line connecting the injection nozzle 15 and the material inlet 17, and the purge resin is transferred to the purge receiving device 16. The swash plate 20 causes the liquid to be injected into the box-shaped body of the fuselage, and is ejected from the fuselage by the swash plate 20.

Since the actions described above are performed,
Not only can the purge resin be discharged out of the aircraft without manual intervention, but the purge resin is also injected into the casing of the purge receiver, eliminating the possibility of material scattering.

In the above embodiment, an example was explained in which an air cylinder was used to drive the arm, but it is needless to say that the invention is not limited to this.

In addition, as shown in Fig. 4, when purging the purge receiving device 16, the purge resin is blown out from the enclosure to make it easier to discharge outside the aircraft, and the purge resin prevents the purge resin from becoming high temperature due to repeated purging of the purge receiving device 16. It is more effective if nozzles 27 and 28 are provided to blow out air.
