Description

Technical Field

[0001] This utility model relates to the field of foam molding technology, specifically to a casting device for automotive seat components. Background Technology

[0002] Foamed headrests and cushions for car seats are made by pouring polyurethane into a mold. The mold includes an upper mold and a lower mold. The lower mold is usually fixed on a workbench, while the upper mold can be flipped open by manual operation or a drive device to remove the foamed components. Because the upper mold is not completely locked after opening, it may flip automatically, which poses a risk of injury to the operator during the process of removing the components. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automotive seat component casting device to address the shortcomings of the prior art.

A drive cylinder is mounted on the side of the base, connected to the shaft to drive the upper mold to rotate. A support seat is provided at the tail of the upper mold, connected to the base via a guide rail. A receiving groove is machined on the upper end of the support seat, a sealing plate is mounted on the side of the receiving groove away from the upper mold, a stop block is provided within the receiving groove, and a spring is installed between the stop block and the sealing plate. A protrusion that mates with the stop block is machined on the end face of the tail of the upper mold, and a first inclined surface is machined on the end face of the protrusion. A mounting plate is connected to the tail of the base, and a control cylinder is mounted on the mounting plate. The piston end of the control cylinder is connected to the back of the support seat via a connector.

[0005] Furthermore, guide strips are machined on both sides of the stop block, and a guide groove is machined on the side wall of both sides of the receiving groove, and the guide strip slides in the guide groove.

[0006] Furthermore, the surface of the sealing plate is provided with a positioning post one, and the back of the stop block is provided with a positioning post two, with the two ends of the spring respectively fitted onto positioning post one and positioning post two.

[0011] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0012] like Figures 1-4As shown, a casting device for automotive seat components includes a base 1, a lower mold 2 mounted on the base 1, and an upper mold 3 positioned above the lower mold 2. The upper mold 2 and the lower mold 3 are rotatably connected by a shaft 4. A drive cylinder 5 is mounted on the side of the base 1, and the drive cylinder 5 is connected to the shaft 4 to drive the upper mold 3 to rotate. In this embodiment, the base 1 includes a lower base plate 111 and an upper base plate 112, which are connected by a connecting column 113. The lower mold 2 has an installation edge around its perimeter, which is bolted to the upper base plate 112. A clamping block 6 is connected to the connecting column 113. Two identical strips are used, with both sides of the strips fixed to the connecting column 113 by screws. The side of the clamping block 6 is provided with a pin 7. The tail of the driving cylinder 5 is connected to the pin 7. The tail of the lower mold 2 is provided with a bearing seat 8 on both sides. The two ends of the shaft 4 are connected to the bearing seat 8 through the bearing seat. One end of the shaft 4 passes through the bearing seat and is connected to the clamping block 9. One end of the clamping block 9 is provided with a clamping opening, which is fitted onto the shaft 4 and locked by screws on the side. The other end of the clamping block 9 is connected to the pin 10. The piston end of the driving cylinder 5 is connected to the pin 10 through a fisheye connector. The upper mold 3 and the lower mold 2 are opened by the action of the driving cylinder 5.

[0013] The upper mold 3 is provided with a support base 11 at its tail end. The support base 4 is connected to the upper base plate 112 of the base 1 via a guide rail. The upper end of the support base 11 is machined with a receiving groove. A sealing plate 12 is installed on the side of the receiving groove away from the upper mold 3. A stop block 13 is provided in the receiving groove. The stop block 13 slides in the receiving groove. Guide strips 14 are machined on both sides of the stop block 13. A guide groove is machined on the side wall of both sides of the receiving groove. The stop block 13 slides in the receiving groove by sliding the guide strips 14 in the guide groove. A spring 15 is installed between the stop block 13 and the sealing plate 12. A positioning post 16 is provided on the surface of the sealing plate 12. A positioning post 27 is provided on the back of the stop block 13. The two ends of the spring 15 are respectively sleeved on the positioning post 16 and the positioning post 27.

[0014] The upper mold 3 has a protrusion at its tail end face that mates with the stop block 13, and the protrusion end face has a first inclined surface 18, such as... Figure 1 and Figure 3 As shown, when the upper mold 3 and the lower mold 2 are closed, the stop block 13 is pressed against the back of the upper mold 3. When the drive cylinder 5 drives the upper mold 3 to flip, the stop block 13 is first compressed into the receiving groove. In order to facilitate the flipping, the stop block 13 is machined with a second inclined surface 19 on the side near the upper mold 3. When the protrusion at the tail of the upper mold 3 flips over the second inclined surface 19, the stop block 13 is pushed out of the receiving groove and stuck on the first inclined surface 18 under the action of the spring 15, preventing the upper mold 3 from automatically flipping and closing with the lower mold 2.

[0015] The base 1 is connected to a mounting plate at its tail. A control cylinder 20 is mounted on the mounting plate. The piston end of the control cylinder 20 is connected to the back of the support base 11 through a connector. When recasting the component, before starting the drive cylinder 5, the control cylinder 20 controls the support base 11 to move backward, so that the stop block 13 is disengaged from the protrusion on the upper mold 3. Then, the drive cylinder 5 is started, so that the upper mold 3 flips and closes with the lower mold 2 to perform foaming.

[0016] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
