Description

Technical Field

[0001] The present invention relates to a taper profiling support device for on-line rapid adjustment of double-cavity extrusion of automotive seals, and belongs to the field. Background Art

[0002] In current double-cavity extrusion dies for automotive seals, the support device uses a structure composed of the protruding parts of the T-shaped process ribs 1 on both sides of the extrusion outlet 5 of the formed seal product (as shown in Figure 1 、 Figure 2 ), and the support block 4 (as shown in Figure 3 ). It is installed at the die protruding plate part of the extrusion outlet 3 of the formed seal product. After the die-extruded part is initially formed, the two-sided T-shaped process ribs 1 are pasted at the corresponding positions of the product, and the T-shaped support tooling adjusts the product opening.

[0003] Among them, the support block 4 includes a top rod 41, a connecting rod 42, and a clamping plate 44. The top rod 41 is connected to the clamping plate 44 through the connecting rod 42. A clamping groove 43 is provided at the bottom of the clamping plate 44 for clamping on the positioning pin 2. The clamping plate 44 is arranged in the T-shaped straight groove 3, and the top rod 41 is arranged at a position slightly lower than the middle of the two extrusion outlets 5 of the formed seal products.

[0004] In the original design of the support block 4, the position can be adjusted in the Y direction to control the opening. The T-shaped process rib 1 needs to be adjusted with an auxiliary regulating wheel. For a single product, multiple adjustments are required to meet the requirements, and the machine adjustment scrapping cost is relatively high. The two cavities are separated, making it difficult to receive parts and perform on-line adjustment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: how to rapidly and simultaneously adjust the fitting degree of double-cavity products on-line.

[0006] To solve the above technical problem, the technical solution of the present invention is to provide a taper profiling support device for on-line rapid adjustment of double-cavity extrusion of automotive seals, which is characterized in that it includes an extrusion outlet die protruding plate arranged between the bottom surface of the T-shaped straight groove and the positioning pin, and a taper support positioning adjustment device through which the positioning pin can pass. The extrusion outlet die protruding plate is fixedly connected to the taper support positioning adjustment device. The upper end of the taper support positioning adjustment device is a profiling structure, and the profiling structure matches the product structure coming out of the extrusion outlet of the formed seal product.

[0007] Preferably, the upper end of the taper support positioning adjustment device is flush with the upper end of the extrusion outlet die protruding plate.

[0008] Preferably, the extrusion outlet die protruding plate has an inverted U-shaped structure, and the opening of the inverted U-shaped structure is a downward-opening limiting groove.

[0009] Preferably, a lower groove through which a positioning pin can pass is provided at the lower end of the taper support positioning adjustment device. The profiling structure includes an upper groove, a platform is provided at the top of the upper groove, and a tapered transition structure is provided between the upper groove and the platform.

[0010] Preferably, the shape of the tapered transition structure matches the contact part of the product structure coming out of the extrusion outlet of the formed seal product.

[0011] Preferably, the extrusion die forming plate is arranged below the extrusion outlet of the formed seal product, and the taper support positioning adjustment device is arranged close to the extrusion outlet of the formed seal product.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The present invention realizes the functions of online rapid adjustment of the one - mold two - cavity opening and the adhesion of the two cavities. The adjustment is convenient. The opening can be controlled by adjusting the height in the Y - direction. And after designing a product once, the fitting degree of the two - cavity product can be limited by adjusting the height of the taper support tooling. The process rib is cancelled, avoiding multiple designs and modifications, and saving the design and production processing costs. Description of the Drawings
