Description

Technical Field

[0001] The utility model relates to the technical field of automobile moulds, in particular to a foaming mould capable of preventing a skeleton hook from being crushed. Background Art

[0002] The foaming mold is to fill the foaming material directly into the mold, so that the AB raw materials react chemically to form foam plastic parts. In the foaming mold of the car seat, the seat frame is fixed by a wire hook embedded in the foaming mold. The hook product design is mainly to avoid the installation of the upper and lower molds on one side, but there are instabilities due to individual differences and transportation deformation, which leads to frequent mold crushing and product scrapping. There is often overflow of foaming material at the installation of the wire hook, which causes material waste and easily affects the appearance of the product, reducing the quality of the product. Utility Model Content

[0003] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a foaming mold which can avoid frequent mold crushing and reduce the overflow of foaming material and can prevent the skeleton hook from being crushed.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a foaming mold that can prevent the skeleton hook from being crushed, comprising an upper mold, a lower mold and a wire hook, the upper mold is provided with a mounting boss for installing the wire hook, the lower mold is provided with a pit corresponding to the mounting boss, the top surface of the mounting boss is a horizontal penetration surface, a U-shaped wire groove is provided on the penetration surface through a material blocking assembly, the depth of the wire groove is greater than the diameter of the wire hook, and the wire hook is pressed against the bottom of the wire groove when hooking the skeleton assembly.

[0005] Preferably, at least one support frame for holding up and fixing the skeleton assembly is provided inside the upper die of the mold to further limit and fix the skeleton assembly.

[0006] Preferably, the material stop assembly is composed of an inner material stop rib and inner material stop rib side wings, and the inner material stop rib is embedded in the top of the mounting boss to form a U-shaped wire groove on the top of the mounting boss.

[0007] Preferably, the wire hook is installed in the wire groove, leaving a gap of 0.8 to 1.2 mm from the side wings of the inner stop rib and the installation boss.

[0008] Preferably, two mounting bosses are symmetrically provided.

[0009] The beneficial effects of the utility model are as follows: by only setting a wire groove with a depth greater than the wire hook on the upper mold of the mold, the wire hook is fixed to the upper mold of the mold during installation and transportation, reducing the damage caused by extrusion of the mold and errors when closing the mold, and can better play a positioning role when installing and fixing the skeleton assembly, and at the same time can avoid the situation where the mold is crushed due to deformation of the skeleton assembly and the product is scrapped; compared with the traditional inclined surface, the horizontal penetration surface can better reduce the overflow of the foaming material, save materials, avoid thermal cracking of the product, and improve the compressive strength of the product.

[0016] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figure 1 As shown in FIG. 5 , a foaming mold capable of preventing injuries caused by a skeleton hook is mainly composed of an upper mold A, a lower mold B and a wire hook 6. The skeleton assembly C is fixedly installed in the foaming mold through the wire hook 6.

[0018] The upper mold A of the mold is provided with a mounting boss for mounting the wire hook 6. In order to make the wire hook 6 more stable when hooking the fixed frame assembly C, two mounting bosses are symmetrically provided. The top surface of the mounting boss is a horizontal penetration surface 5, which can better reduce the overflow of the foaming material, and a U-shaped wire groove 1 is provided on the penetration surface 5 through a material blocking component. The depth of the wire groove 1 is greater than the diameter of the wire hook 6. When the wire hook 6 hooks the frame assembly C, it is pressed against the bottom 4 of the wire groove. The material blocking component is composed of an inner material blocking rib 2 and an inner material blocking rib wing 3. The inner material blocking rib 2 is embedded in the top of the mounting boss, forming a U-shaped wire groove 1 at the top of the mounting boss. In order to avoid the instability of individual frame welding deformation, transportation deformation and other factors with a difference of 5-10mm, which leads to frequent mold crushing and product scrapping, when the wire hook 6 is installed in the wire groove 1, a gap of 0.8-1.2mm is left between the inner material blocking rib wing 3 and the mounting boss.

[0019] The lower die B of the mold is provided with a pit corresponding to the mounting boss, and the bottom of the pit is a plane. When the mold is closed, the bottom of the pit fits with the penetration surface 5, and at least one support frame for holding up and fixing the skeleton assembly C is provided inside the lower die B of the mold.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
