[0002] Car seat foam molds are used to produce car seat foam parts. After use, car seat foam molds need to be stored. There is surface contact between the foam mold and the mold frame. Moreover, the foam mold itself is very heavy and requires a lot of force to push the mold into the mold frame. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a mold frame for foaming automobile seats, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A mold frame for foaming automotive seats includes a bottom support, a mold frame platform connected to the periphery of the bottom support by support rods, an intermediate support connected to the support rods, a screw jack mounted on the intermediate support, a support plate connected to the screw jack, support frames evenly distributed on the support plate, and rollers connected to the upper ends of the support frames by shafts. The surface of the mold frame platform is provided with roller clearance holes, and the screw jack controls the rollers to extend out of the roller clearance holes. Positioning blocks are provided on three sides of the mold frame platform, and a retractable positioning pin is provided on the other side of the mold frame platform.

[0006] Furthermore, two screw jacks are installed on the intermediate support, and a drive shaft is provided between the two screw jacks. A hand crank is connected to the side of the screw jack near the positioning pin.

[0007] Furthermore, the drive shaft is connected to the rotating shaft on the screw jack via a coupling.

[0008] Furthermore, a positioning pin sleeve is provided inside the mold frame platform, the positioning pin is set inside the positioning pin sleeve, a positioning pin hole is opened at the upper end of the positioning pin sleeve, the positioning pin passes through the positioning pin hole, a flange is provided at the bottom of the positioning pin and is stuck below the positioning pin hole, and a spring is provided at the bottom of the flange.

[0009] Furthermore, the bottom bracket is equipped with swivel casters with brakes.

[0010] Compared with the prior art, the mold frame for foaming car seats of this utility model changes sliding friction to rolling friction through liftable rollers when the mold is stored, so that the foaming mold can be easily pushed into the mold frame, saving the operator's physical strength.

Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0016] like Figures 1-3 As shown, a mold frame for foaming automotive seats includes a bottom support 1. The bottom support 1 is equipped with swivel casters 2 with brakes, which facilitate movement of the mold frame. A mold frame platform 3 is connected to the bottom support 1 via support rods. An intermediate support 4 is connected to the support rods, and a screw jack 5 is mounted on the intermediate support 4. A support plate 6 is connected to the screw jack 5, and support frames 7 are evenly distributed on the support plate 6. Rollers 8 are connected to the upper ends of the support frames 7 via shafts. The surface of the mold frame platform 3 is provided with roller clearance holes 9. During the storage of the foaming mold, the screw jack 5 controls the rollers 8 to extend out of the roller clearance holes 9, and the foaming mold is pushed into the mold frame through the rollers 8. Rolling friction replaces sliding friction, saving the operator's physical effort.

[0017] The mold frame platform 3 is provided with positioning blocks 10 on three sides, and a retractable positioning pin 11 on the other side. After the foaming mold is pushed into the mold frame, it is positioned by the positioning blocks 10 and the positioning pin 11. The mold frame platform 3 is provided with a positioning pin sleeve 12, and the positioning pin 11 is located in the positioning pin sleeve 12. The upper end of the positioning pin sleeve 12 is provided with a positioning pin hole, and the positioning pin 11 passes through the positioning pin hole. The bottom of the positioning pin 11 is provided with a flange 13 that is stuck below the positioning pin hole. The bottom of the flange 13 is provided with a spring 14, and the spring 14 provides elastic force to make the positioning pin 11 extend out of the positioning pin hole.

[0018] In this embodiment, two screw jacks 5 are installed on the intermediate support 4, and a drive shaft 15 is provided between the two screw jacks 5. The drive shaft 15 is connected to the rotating shaft on the screw jack 5 through a coupling. A hand crank 16 is connected to the side of the screw jack 5 near the positioning pin 11. The hand crank 16 controls the lifting and lowering of the screw inside the screw jack 5. During the process of pushing the foaming mold into the mold frame, the hand crank 16 is rotated to make the roller 8 rise and protrude out of the roller clearance hole 9 to contact the bottom of the foaming mold.

[0019] 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.
