[0030] See attached Figure 1-4 , a foaming mold for a rear seat of an automobile, comprising:

[0031] The upper mold 1 is provided with a water inlet pipe 2 and a water outlet pipe 3 on one side, and two symmetrical square steels are provided on both sides of the top; two sets of mutually colliding steel ball springs 4 are provided inside the upper mold 1; and two symmetrical error-proofing limit holes 13 are opened on the upper mold 1;

[0032] The steel wire skeleton 5 is fixed in the upper mold 1; the steel wire skeleton 5 is provided with an upward locking hook 6, which corresponds to the collision area of ​​the steel ball spring 4 and passes through the anti-mistake limit hole 13 at the corresponding position for positioning and locking;

[0033] Exhaust pins 7 are provided in plurality on the top of the upper mold 1, and their main function is to exhaust air so as to reduce defects such as product shortage;

[0034] The lower mold 8 has a water inlet pipe 9 and a water outlet pipe 10 on one side; a foaming groove is provided inside the lower mold 8, and a foaming steel wire 11 is arranged in the foaming groove, which cooperates with the steel wire skeleton 5 or felt cloth, Velcro and other accessories to play a positioning role;

[0035] The coiled water pipe 12 is provided in each of the upper mold 1 and the lower mold 8, and is respectively connected to the water inlet pipe 2 and the water outlet pipe 3 as well as the water inlet pipe 9 and the water outlet pipe 10 at the corresponding positions; the coiled water pipe 12 is made of stainless steel water pipe, and the water is heated by the mold temperature controller. The hot water circulates continuously in the stainless steel water pipe to conduct heat so that the mold is heated to between 55-65°C, meeting the necessary conditions for producing products.

[0036] In this embodiment, the production process is: install the mold frame → connect the air source and water source → open the upper mold 1 → evenly spray the release agent on the upper mold 1 and the lower mold 8 → turn off the square cylinder switch → weld the steel wire skeleton 5 and put the locking hook 6 into the anti-error limit hole 13 → foam steel wire → set the pouring parameters → automatic pouring by the machine → close the mold → open the mold after 4 minutes → take out the product → open the foam with a vacuum machine → trim and repair → check according to the inspection guidance → put on the shelf as required → put into storage.

[0037] Working principle: Connect the water inlet and outlet of the foaming mold to the disc line water pipe 12, and control the mold temperature between 55℃-65℃ through the mold temperature controller; connect the air source to the air inlet of the air valve component and open the mold frame; push the "double-axis cylinder switch" insert downward and return it, put in the steel wire skeleton 5 and the foam steel wire, push the "double-axis cylinder switch" insert upward and push it in to seal with the connecting sheet on the angle adjuster, and after pouring according to the trajectory in the operation instructions, press the upper mold closing switch to close the mold and the air bag to rise and lock the mold; after 2 minutes of curing, open the mold, push the "double-axis cylinder switch" insert downward and return it, open the Fanggang switch to eject the foam, and complete the removal.

[0038] The upper mold 1 and the lower mold 8 are made of sand casting aluminum, play a role in product molding, and are installed on the mold frame. The water inlet pipe 1 2, the water outlet pipe 1 3, the water inlet pipe 2 9 and the water outlet pipe 2 10 are located on the same side, which is convenient for connecting the mold temperature controller to heat water to heat the mold.

[0039] In addition, a plurality of clamps 14 are arranged around the interior of the upper mold 1; the steel wire skeleton 5 includes an upper skeleton and a lower skeleton, wherein the upper skeleton is provided with a plurality of reinforcing rods 15, and the lower skeleton is clamped on the clamps 14. A plurality of protruding modules are arranged inside the upper mold 1, and a spacing groove is reserved between the protruding modules and the inner wall of the upper mold 1 for the outer ring of the steel wire skeleton 5 to be placed, which is conducive to the foaming material wrapping the steel wire skeleton 5.

[0040] When installing the steel wire skeleton 5, turn the upper mold 1 over so that its inside faces upward, and then press the lock hook 6 of the steel wire skeleton 5 into the anti-error limit hole 13; during the advancement process, the lock hook 6 will pass through the two steel ball springs 4 that collide with each other, and there will be a feeling of being locked, and it is not easy to pull out, which is convenient for employees to identify unqualified skeletons. The steel wire skeleton 5 that is easily pulled out after being locked is unqualified. By screening out unqualified steel wire skeletons 5, it is helpful to reduce the scrapping of foam tooling due to unqualified or falling steel wire skeletons 5, and reduce losses while ensuring the size, relative position, installation surface, hole, and position of the foam skeleton.

[0041] The automobile rear seat foaming mold of the utility model can achieve accurate positioning through the collision of steel ball springs 4, and the steel wire frame 5 is installed firmly without looseness, and has an error-proofing function during positioning, which can avoid the steel wire frame 5 from falling off or unqualified frames from causing foam scrapping and labor costs, and is beneficial to improving product quality, avoiding unqualified products from being left to the next process and customers, and meeting customer expectations. It is very practical and has good market application prospects.

[0042] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes. The scope of the utility model is intended to be defined by the claims and their equivalents.
