[0001] This utility model relates to the field of automotive interior parts manufacturing, and in particular to an automatic sealing structure for a closed-mold foaming gating sleeve for automotive interior parts. Background Technology

[0002] In automotive interior parts, a material-blocking structure needs to be designed at the injection port of the foaming mold for closed-mold foaming. The commonly used structure is a manual clamp or a pneumatic clamp. However, this clamp structure occupies a lot of space when open and is prone to interference with the foaming gun head or overflow problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an automatic sealing structure for closed-mold foaming gate sleeves of automotive interior parts. It achieves automated production through pneumatic control, and ensures that it does not interfere with the nozzle and does not overflow.

[0004] The technical solution adopted by this utility model to solve its technical problem is: An automatic sealing structure for a closed-mold foaming sprue sleeve for automotive interior parts includes a cylinder 1, a sealing plate 2, a cylinder connector 3, a sprue sleeve 4, and guide strips 5; wherein, the cylinder connector 3 of the cylinder 1 is connected to the sealing plate 2; vertical guide strips 5 are respectively installed on both sides of the sprue sleeve 4, and the sealing plate 2 is installed inside the two guide strips 5.

[0005] This utility model also has the following additional technical features: As a further specific optimization of the technical solution of this utility model, the cylinder 1 is installed on the cylinder fixing bracket by bolts, and the cylinder fixing bracket is installed on the mold by bolts.

[0006] As a further specific optimization of the technical solution of this utility model, the cylinder connector 3 is provided with a connecting block with a convex structure, and the sealing plate 2 is provided with a connecting groove with a convex structure. The connecting block is engaged with the connecting groove for integrated connection.

[0007] As a further specific optimization of the technical solution of this utility model, the bottom of the sealing plate 2 is provided with a convex slider, and the inner side of the guide strip 5 is provided with a concave guide groove. The slider of the sealing plate 2 is locked and installed in the guide groove of the guide strip 5.

[0008] As a further specific optimization of the technical solution of this utility model, the movement of the cylinder 1 drives the cylinder connector 3 to move, and the movement of the cylinder connector 3 drives the sealing plate 2 to move. Due to the guiding effect of the guide strip 5, the sealing plate 2 moves linearly between the guide strips 5, which can be used to automatically seal the sprue sleeve 4.

[0009] Compared with the prior art, the advantages of this utility model are: This invention achieves automated production through pneumatic control, ensuring no interference with the nozzle and preventing material overflow. Attached Figure Description

[0012] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0013] An automatic sealing structure for a closed-mold foaming sprue sleeve of automotive interior parts includes a cylinder 1, a sealing plate 2, a cylinder connector 3, a sprue sleeve 4, and guide strips 5. The cylinder 1 is bolted to a cylinder mounting bracket, which is bolted to the mold. The cylinder connector 3 of the cylinder 1 is connected to the sealing plate 2, and the cylinder connector 3 has a convex connecting block. The sealing plate 2 has a convex connecting groove, and the connecting block engages with the connecting groove for an integrated connection. Vertical guide strips 5 are installed on both sides of the sprue sleeve 4. The sealing plate 2 is installed inside the two guide strips 5, and the bottom of the sealing plate 2 has an outwardly convex slider. The inner side of the guide strips 5 has an inwardly concave guide groove, and the slider of the sealing plate 2 engages with and is installed in the guide groove of the guide strip 5.

[0014] The working principle of an automatic sealing structure for a closed-mold foaming gate sleeve for automotive interior parts: When the mold is closed, the foaming gun head begins to inject material. At this time, cylinder 1 is in the retracted state, and sealing plate 2 is in the retracted state. After the injection is completed, the gun head is moved away, cylinder 1 is ejected, and sealing plate 2 is in the ejected state, which just blocks the injection port to prevent the foaming material from overflowing. After the pressure holding is completed, cylinder 1 retracts, sealing plate 2 retracts, and the foamed product and waste material in the injection port are removed.

[0015] The movement of cylinder 1 drives the movement of cylinder connector 3, which in turn drives the movement of sealing plate 2. Due to the guiding effect of guide strip 5, sealing plate 2 moves linearly between guide strip 5, which can be used to automatically seal the sprue sleeve 4.

[0016] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
