Description

Technical Field

[0001] The invention relates to the technical field of mold processing, and in particular to a vertical surface drawing groove mold used for seat foaming. Background Art

[0002] As the mileage of automobiles continues to increase, the functions and shapes of automobile accessories are becoming more and more complex. However, some functions and shapes are not conducive to the manufacture of automobile foam products. For example, adding style grooves to the vertical surface of the seat foam is a typical structure.

[0003] Since the style groove is formed on the vertical side wall of the product, a core is usually set in the mold at the position corresponding to the style groove during the foaming process. However, the setting of the core not only hinders the foam from rising upward, but also causes air to be trapped on the upper and lower sides of the style groove, causing product defects. Repairing defective products is very time-consuming and labor-intensive. Summary of the invention

[0004] In view of this, the present invention provides a vertical drawing groove mold for seat foaming, aiming to improve the yield rate of foam products with style grooves.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A vertical drawing groove mold for seat foaming, comprising an upper mold and a lower mold arranged vertically opposite to each other, characterized in that: a first core that can move up and down is installed on the lower side of one end of the upper mold, and a second core that can flip outward is installed on the lower side of the first core. The upper mold is equipped with a first driving mechanism and a second driving mechanism. The first driving mechanism is used to drive the first core to move up and down, and the second driving mechanism is used to drive the second core to flip inward or outward on the lower side of the first core; when the first core moves up to fit with the lower side of the upper mold, and the second core flips inward to fit with the lower side of the first core, the inner sides of the first core and the second core can be combined to form a molding surface, and the molding surface is used to form a vertical style groove of the molded product.

[0007] By adopting the above structure, through the combined design of the first core and the second core, while ensuring that the style groove can be formed, the microscopic gap between the first core and the second core can also facilitate the ventilation of the foam during the foaming process, thereby avoiding defects after foaming. The first core and the second core are both movably installed, and through the combination of linear motion and rotation, the finished product after foaming can be easily demolded.

[0008] Preferably, the inner side of the lower end of the first core is configured as an arc structure, and the lower end of the second core has an arc-shaped mounting protrusion, and after the inner sides of the first core and the second core are combined, the arc-shaped protrusion can protrude inwardly beyond the first core. With the above structure, the arc-shaped protrusion can facilitate the formation of the style groove.

[0009] Preferably, the first driving mechanism comprises a first telescopic cylinder, the cylinder seat of the first telescopic cylinder is fixedly arranged at one end of the upper mold in the vertical direction, and the middle part of the upper end of the first core is fixedly connected to the cylinder rod of the first telescopic cylinder. With the above structure, the first core can be stably moved up and down.

[0010] Preferably, the second driving mechanism comprises a second telescopic cylinder, the cylinder seat of the second telescopic cylinder is fixedly arranged on the first core, the end of the cylinder rod of the second telescopic cylinder is rotatably connected to a connecting rod, the other end of the connecting rod is rotatably connected to the second core, and the outer end of the second core is rotatably connected to the first core. With the above structure, the rotation of the second core can be realized, and the connecting rod makes the second core rotate at a larger angle relative to the first core.

[0011] Preferably, two groups of the second telescopic cylinders are provided, and the two groups of the second telescopic cylinders are symmetrically arranged at the two ends of the first core, and the two ends of the second core are respectively hinged on the corresponding connecting rods. The above structure can make the rotation of the second core more stable.

[0012] Preferably, the upper mold is symmetrically provided with movable holes on both sides, and the second telescopic cylinder is inserted into the movable holes. The above structure can avoid interference between the telescopic cylinder and the upper mold to affect the up and down movement of the first core.

[0013] Preferably, the first core and the second core are rotatably connected via a hinge. With the above structure, the second core can be rotatably mounted on the first core.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The vertical drawing groove mold for seat foaming provided by the present invention is designed through the combination of the first core and the second core. While ensuring that the style groove can be formed, the microscopic gap between the first core and the second core can also facilitate the ventilation of the foam during the foaming process, thereby avoiding defects after foaming, and ensuring the yield rate of foam products with style grooves. The first core and the second core are both movably installed, and through the combination of linear motion and rotation, the finished product after foaming can be easily demolded.

[0020] The present invention is further described below in conjunction with embodiments and drawings.

[0021] like Figure 1 and Figure 4 As shown, a vertical drawing groove mold for seat foaming includes an upper mold 1 and a lower mold 2 arranged opposite to each other in the upper and lower sides, a first core 3 that can move up and down is installed on the lower side of one end of the upper mold 1, and a second core 6 that can be turned outward is installed on the lower side of the first core 3. The upper mold 1 is equipped with a first driving mechanism and a second driving mechanism. The first driving mechanism is used to drive the first core 3 to move up and down, and the second driving mechanism is used to drive the second core 6 to turn inward or outward at the lower side of the first core 3.

[0022] In this embodiment, the upper end of the lower mold 2 has a concave mold cavity 2a for molding products, and the lower end of the upper mold 1 has a convex mold 1b. When the mold produces the foam product 9, first, the first driving mechanism drives the first core 3 to move up to the lower side of the upper mold 1 and the second driving mechanism drives the second core 6 to flip inward to be in close contact with the lower side of the first core 3, and then the upper mold 1 is closed downward at the upper end of the lower mold 2. At this time, the convex mold 1b, the concave mold cavity 2a, and the first core 3 and the second core 6 form a foaming cavity similar to the foam product 9, wherein the inner side of the combined first core 3 and the second core 6 is similar to the vertical style groove of the side wall of the foam product 9. Therefore, by filling the foaming material into the mold, the foam product 9 with the style groove 9a can be formed.

[0023] During the product molding process, after the first core 3 and the second core 6 are assembled up and down, there must be a microscopic gap between the two, which can play the role of exhausting air during the foaming process, thereby avoiding defects in the vertical groove area of ​​the foamed product, thereby improving the foaming yield of the foam product 9 with the style groove 9a. In addition, the first core 3 and the second core 6 are both movably installed, and the combination of linear motion and rotation is more conducive to the demoulding of the foam product 9.

[0024] Further, combined with Figure 1 , Figure 2 and Figure 4The first core 3 is constructed into an arc structure adapted to the cross section of the style groove 9a. The lower end of the second core 6 has an arc-shaped protrusion 6a. After the first core 3 and the inner side of the second core 6 are combined, the arc-shaped protrusion 6a can protrude inwardly beyond the first core 3. At this time, the arc-shaped protrusion 6a can be used to form the style groove 9a, and the microscopic gap between the first core 3 and the second core 6 is conducive to the ventilation of the foam during foaming.

[0025] like Figure 1 As shown, the first driving mechanism includes a first telescopic cylinder 4, a cylinder base of the first telescopic cylinder 4 is fixedly installed in the middle of the position corresponding to the style groove 9a of the upper mold 1 in the vertical direction, and the middle of the upper end of the first core 3 is fixedly connected to the cylinder rod of the first telescopic cylinder 4. Such a design can make the first core 3 move up and down in the vertical direction more stably.

[0026] For example Figure 1 As shown, the second driving mechanism includes a second telescopic cylinder 5, the cylinder seat of the second telescopic cylinder 5 is fixedly mounted on the first core 3, the cylinder rod end of the second telescopic cylinder 5 is rotatably connected to a connecting rod 7, the other end of the connecting rod 7 is rotatably connected to the second core 6, and the outer end of the second core 6 is rotatably connected to the first core 3. With such a design, the rotation of the second core 6 can be realized, and the connecting rod 7 can increase the rotation angle of the second core 6 relative to the first core 3, thereby further facilitating the demoulding of the foam product 9.

[0027] In this embodiment, two groups of second telescopic cylinders 5 are provided, and the two groups of second telescopic cylinders 5 are symmetrically installed at both ends of the first core 3. The two ends of the second core 6 are respectively hinged on the corresponding connecting rods 7. Such a design can ensure a more stable rotation of the second core 6.

[0028] like Figure 1 As shown, movable holes 1a are symmetrically arranged on the left and right sides of the upper mold 1, and the second telescopic cylinder 5 is penetrated in the movable holes 1a. Such a design can avoid motion interference between the second telescopic cylinder 5 and the upper mold 1, thereby ensuring that the first core 3 can move up and down in the vertical direction.

[0029] like Figure 3 As shown, the first core 3 and the second core 6 are connected via a hinge 8 , and the hinge 8 enables the second core 6 to be rotatably installed relative to the first core 3 .

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
