本考案は、たとえばウレタンシートパツドを製

である。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a low-pressure injection machine used, for example, in manufacturing urethane sheet pads.

くしている。(Prior art) Conventionally, low-pressure injection machines for urethane sheet pads mix, react, and cure several types of raw materials, but each raw material has a different viscosity and a different discharge amount per unit time. , orifices of different sizes are used for each raw material.
In particular, for catalyst system raw materials that require a small flow rate, the orifice diameter is made small to 0.9 to 1.1 mm in order to prevent excessive flow.

調整するためのコントロールバルブの循環側への
設置およびコントロール作業を必要とする。(Problems to be solved by the invention) If the diameter of the orifice is small, the hardened material will clog near the orifice, resulting in poor injection and eventually stopping the operation of the process. Furthermore, when changing the required flow rate due to a large pressure increase at the orifice, the pressure during circulation when not in use and the pressure during discharge, which have been previously adjusted to the same value, will be inconsistent, causing fluctuations in the discharge flow rate. Therefore, it is necessary to install a control valve on the circulation side and perform control work to adjust the pressures of both to the same level when the flow rate fluctuates.

れるが、本実施例においては６ポートである。 The raw material supplied from the raw material tank to the injection head 1 via the pump flows into the injection head 1 through the outlet 2a of the nipple 2 attached to the inlet 1a. At this time, if the stem 3 is raised, the outlet 1b is closed by the stem 3 and the raw material is not circulated. Then, it enters the housing 5 through the orifice 4, is stirred by the mixer 7 attached to the mixer shaft 6, and is discharged from the nozzle 8 into the urethane mold. After the discharge is completed, the housing 5
Clean the inside with cleaning solution. If discharge and cleaning are repeated for a long period of time, the raw material may harden inside the housing 5 and small lumps may be generated, but since the orifice 4 is larger than the conventional one,
No clogging occurs in the orifice 4 due to the small lumps. When the raw material is not being supplied into the housing 5, the stem 3 is lowered, the orifice 4 is closed, and the raw material enters the injection head 1 through the inlet 1a, immediately exits through the outlet 1b, and is circulated. Ru. In this case, since there is no pressure increase in the orifice 4, a control valve for adjusting the circulation pressure and the discharge pressure to be equal when the flow rate fluctuates, which was conventionally installed in the circulation system, becomes unnecessary. In FIG. 1, a raw material different from the raw material supplied from nipple 2 is supplied from nipple 2', but in this embodiment, there are 6 ports.

が得られる。(Effects of the invention) As described above, according to the invention, a nipple having a discharge port at the tip, the diameter of which varies depending on the raw material, is attached to the inlet of the injection head, so the size of the orifice can be increased. This eliminates clogging on the circulation side and eliminates the need for a control valve and control work on the circulation side.
