Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to a molding mold for a side guard plate of an automobile seat. Background Art

[0002] Some automotive parts with complex structures need to be processed and formed by injection molds, but the molded products often have mold sticking phenomenon. Simply put, the product is tightly connected to the internal structure of the mold, making it difficult to demold the product.

[0003] Figure 1 The figure shows the structure of the side guard plate of an automobile seat. Generally, a traditional mold will use a straight-top mechanism to push the product (side guard plate) out of the mold cavity. However, since a buckle 111 is provided on the side guard plate, the demolding direction of the buckle 111 is inconsistent with the mold opening direction of the mold. The side guard plate cannot be demolded by using an ordinary straight-top structure. Therefore, mold engineers are required to design a new and reasonable demolding structure to solve the demolding problem of the side guard plate of the automobile seat. Summary of the invention

[0004] The utility model aims to provide a molding die for a side guard plate of an automobile seat, so as to solve the problems mentioned in the background technology.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a molding die for a side guard plate of an automobile seat, comprising a straight ejector assembly, an inclined ejector assembly and a top plate assembly movable in a vertical direction; the straight ejector assembly comprises a first insert, a push block and a straight ejector rod, the inclined ejector assembly comprises a second insert, a guide assembly and an inclined ejector rod; the first insert is provided with a convex column molding structure, the second insert is provided with a buckle molding portion, and the first insert is plug-connected with the second insert; the push block is movably connected with the first insert, one end of the straight ejector rod passes through the push block and is connected with the first insert, and the other end of the straight ejector rod is connected with the top plate assembly; one end of the inclined ejector rod is connected with the second insert, and the other end of the inclined ejector rod is connected with the guide mechanism on the top plate assembly; the straight ejector rod is erected on the top plate assembly in a vertical direction, the inclined ejector rod is arranged obliquely, and an angle α is formed between the straight ejector rod and the inclined ejector rod, 0°<α<90°.

[0006] Compared with the prior art, the utility model has the advantages that the traditional straight top structure cannot be demoulded smoothly because the demoulding direction of the buckle on the side guard plate is inconsistent with the mold opening direction of the mold. By introducing the inclined top assembly and the straight top assembly, the inclined arrangement of the inclined top rod and the ejection effect of the straight top rod enable the side guard plate to be smoothly separated from the mold, ensuring the smooth progress of the production process; the buckle part on the side guard plate is a key part in the demoulding process of the mold. The traditional straight top structure may cause the buckle to be blocked or damaged. The design of the mold takes into account the existence of the buckle. Through the plug-in connection of the first insert and the second insert and the setting of the buckle forming part, it is ensured that the buckle can be demoulded smoothly without being damaged or deformed, thereby protecting the integrity and quality of the side guard plate. The design of the mold adopts the synergistic effect of the straight top rod and the inclined top rod, and a specific angle is formed between the straight top rod and the inclined top rod. Such a design enables the demoulding process to be controlled more accurately, ensuring the accuracy of the position and angle of the side guard plate during the demoulding process.

[0007] Demolding process: the mold is separated, the driving device drives the top plate assembly to move upward, and the inclined ejector rod moves sideways while moving upward, so that the second insert is smoothly separated from the buckle part of the side guard plate. At the same time, the straight ejector assembly comes into play. One end of the straight ejector rod passes through the push block and is connected to the first insert, and the other end is connected to the ejector rod assembly on the top plate assembly. When the top plate assembly moves upward, the straight ejector rod extends upward in the vertical direction and acts on the convex column forming structure on the first insert through the push block. This makes the first insert and the side guard plate move upward as a whole, thereby ejecting the mold cavity, and the demolding is completed.

[0008] In some embodiments of the utility model, the convex column forming structure includes a notch and a forming channel, the notch is located at the top of the first insert, the forming channel is located in the first insert, and one end of the forming channel leads to the notch. Such a design allows the mold to be guided by the convex column forming structure during the demolding process, ensuring that the buckle part of the side guard plate can be smoothly separated from the mold, thereby protecting the integrity and quality of the buckle.

[0009] In some embodiments of the present invention, a socket is provided on the second insert, a molded end is provided on one side of the socket, the molded end cooperates with the recess, and a side of the first insert adjacent to the recess cooperates with the socket.

[0010] In some embodiments of the utility model, an ejector pin is further provided in the first insert, the ejector pin is movably fitted in the forming channel, and one end of the ejector pin is connected to the forming end.

[0011] In some embodiments of the present invention, an elastic member is provided in the molding channel, and the elastic member is sleeved with the ejector pin.

[0012] In some embodiments of the present invention, the first insert block and the push block are connected in a "T" shape.

[0013] In some embodiments of the utility model, the guide mechanism includes a guide seat and a guide block, the guide seat is fixedly connected to the top plate assembly, a guide groove is provided in the guide seat, the guide block is movably fitted in the guide groove, and the inclined ejector rod is connected to the guide block. The guide block is matched with the guide groove. The inclined ejector rod is connected to the guide block. The existence of the guide mechanism ensures the accurate positioning and guiding effect of the inclined ejector rod during the demoulding process, so that the side guard plate can be smoothly separated from the mold, and the accuracy and stability of demoulding are guaranteed.

[0027] In the above structure: the traditional straight top structure cannot be demoulded smoothly because the demoulding direction of the buckle on the side guard plate is inconsistent with the mold opening direction of the mold. By introducing the inclined top assembly and the straight top assembly, the inclined arrangement of the inclined top rod 5 and the ejection effect of the straight top rod 3 enable the side guard plate to be smoothly separated from the mold, ensuring the smooth progress of the production process; the buckle part on the side guard plate is a key part in the mold demoulding process.

Through the plug-in connection of the first insert 1 and the second insert 4 and the setting of the buckle forming part 7, it is ensured that the buckle can be demoulded smoothly without being damaged or deformed, thereby protecting the integrity and quality of the side guard plate. The design of the mold adopts the synergistic effect of the straight top rod 3 and the inclined top rod 5, and a specific angle is formed between the straight top rod 3 and the inclined top rod 5.

Such a design allows the mold to be guided by the convex column forming structure 6 during the demoulding process, ensuring that the buckle part of the side guard plate can be smoothly separated from the mold, thereby protecting the integrity and quality of the buckle.

[0030] Specifically, the second insert 4 is provided with a socket 8 , one side of the socket 8 is provided with a molded end 9 , the molded end 9 matches with the notch 601 , and the side of the first insert 1 adjacent to the notch 601 matches with the socket 8 .
