[0002] Molds, as an indispensable and key tool in modern industrial production, are of self-evident importance. They are carefully designed and manufactured to shape raw materials (such as metals, plastics, rubber, etc.) into products or product components of the desired shape and size through pressure, temperature, or a combination of these under specific conditions. During the use of the mold, the raw materials are injected or placed into the mold cavity. Subsequently, through the action of equipment such as presses, injection molding machines, or die-casting machines, the raw materials undergo physical or chemical changes within the mold, and eventually cool and solidify to form the desired product. This process not only enables large-scale and efficient production, but also ensures product consistency and interchangeability. It is one of the important means for modern industrial production to achieve automation, standardization, and efficiency.

[0003] For example, the invention patent with application number CN202211444177.1, entitled "A Helmet Molding Mold," includes a first molding mold, a second molding mold, and a third molding mold. The first molding mold is provided with a first cavity for molding a first molding portion of a helmet shell, the second molding mold is provided with a second cavity for molding a second molding portion of a helmet shell, and the third molding mold is provided with a third cavity for molding a third molding portion of a helmet shell. The helmet shell is molded in sequence using the first molding mold, the second molding mold, and the third molding cavity to obtain an integrally molded first molding portion, a second molding portion, and a third molding portion. However, the molding of protruding portions such as the jaw guard by this mold is relatively rough, and burrs are easily formed on the surface, which can easily cause scratches on the hands.

[0009] Furthermore, the right module is provided with two driving grooves arranged opposite to each other, and the driving part of the external driving mechanism is embedded in the driving grooves.

[0010] Furthermore, the two driving grooves are respectively arranged on the two side surfaces connected to the parting surface of the right module.

[0011] Furthermore, the driving groove is a "T"-shaped groove.

[0012] Furthermore, at least two guide bosses are provided on the parting surface of the right module, and guide grooves corresponding to the guide bosses are provided on the parting surface of the left module, and the guide bosses are embedded in the guide grooves.

[0013] Furthermore, the number of the guide protrusions and the number of the guide grooves are both four, and the four guide protrusions and the four guide grooves are respectively distributed at the four corners of the parting surface.

[0014] Furthermore, a mounting channel is provided on the right module, one end of the guide boss is embedded in the mounting channel, a connecting rod is provided in the mounting channel, and the end of the connecting rod is fixedly connected to one end of the guide boss.

[0032] Example

[0033] Please refer to Figure 1-5 As shown, this embodiment provides a helmet shell edge inner-wrapped molding die, including an air bag (not shown in the accompanying drawings), a left module 1 and a right module 2. The left module 1 and the right module 2 are provided with molding grooves 11 on the opposite sides. The molding grooves 11 enclose a molding cavity 12. The air bag is fixed on a template (not shown in the accompanying drawings). The molding cavity 12 is provided with a top opening 121. The air bag is embedded in the molding cavity 12 through the top opening 121. The template cover is provided on the top of the left module 1 and the right module 2. The air bag is spaced apart from the inner side wall of the molding groove 11 to form a molding space for molding the helmet. Similarly, the air bag can correspond to other structures and mold other products. At least one outwardly protruding molding protrusion 3 is provided on the inner side surface of the left module 1 and the right module 2, and the molding protrusion 3 is spaced apart from the air bag.

[0034] The molding protrusion 3 protrudes from the inner side surfaces of the left module 1 and the right module 2, occupying the molding space. After the helmet is pressure-molded in the molding space, an inner packaging structure is formed on the outer side surface of the jaw guard structure or around the window, lower periphery and ventilation hole. This makes the edge of the jaw guard structure, the edge of the window, the lower periphery and the edge of the ventilation hole smoother and flatter, avoiding the formation of burrs, reducing the sharpness of other structures such as the edge of the jaw guard structure, and thus avoiding cuts to the hands.

[0035] Please refer to Figure 2-4 As shown, in this embodiment, a first clearance groove 13 and a second clearance groove 21 are respectively provided on the inner side surfaces of the left module 1 and the right module 2. The sides of the first clearance groove 13 and the second clearance groove 21 are connected to each other. The first clearance groove 13 and the second clearance groove 21 correspond to the position of the jaw guard. A jaw guard insert 31 is embedded in the first clearance groove 13 and the second clearance groove 21. The jaw guard insert 31 protrudes from the first clearance groove 13 and the second clearance groove 21 to form a molding protrusion 3. The jaw guard insert 31 is spaced apart from the airbag. Since the jaw guard insert 31 is a protruding structure, it is easy to cause wear during the molding process, affecting the molding accuracy of the helmet jaw guard structure. The jaw guard insert 31 is independent of the left module 1 and the right module 2, which facilitates the disassembly and replacement of the jaw guard insert 31, thereby improving the molding accuracy of the helmet jaw guard mechanism. Similarly, the inner surfaces of the left and right modules 1 and 2 can also be provided with recessed clearance grooves based on the positions of the lower perimeter structure, the top vent structure, and other structures of the helmet. Inserts of corresponding structures can be placed within the recesses. After molding, these recesses can be formed into inner-enclosed structures at each location, further reducing the sharpness of the helmet as a whole, saving costs, reducing the difficulty of polishing, and improving production efficiency. That is, in this embodiment, the molded protrusions also include a window protrusion (not shown in the drawings), a lower perimeter protrusion (not shown in the drawings), and a vent protrusion (not shown in the drawings). Inner-enclosed structures can be formed at the window, lower perimeter, and vent locations, further reducing the sharpness of the helmet as a whole, saving costs, reducing the difficulty of polishing, and improving production efficiency.

[0036] Please refer to Figure 1 and Figure 2 As shown, the right module 2 is provided with two drive grooves 22 arranged opposite to each other, and the drive portion of the external drive mechanism is embedded in the drive grooves 22. The external drive mechanism drives the right module 2 to move toward or away from the left module 1, thereby achieving mold closing and mold opening. In this embodiment, the two drive grooves 22 are respectively arranged on the two side surfaces connected to the parting surface 14 of the right module 2. The drive portion of the external drive mechanism is in contact with the side opposite to the parting surface 14 of the right module 2 and extends forward to the drive grooves 22, effectively increasing the contact area between the external drive mechanism and the right module 2, ensuring stability when the external drive mechanism drives the right module 2 forward or backward. Similarly, the drive groove 22 can be arranged on the side of the right module 2 opposite to the parting surface 14. In this embodiment, the drive groove 22 is a "T"-shaped groove. The "T"-shaped groove effectively improves the stability of the connection between the right module 2 and the external drive mechanism, preventing the right module 2 from falling off from the external drive mechanism during the driving process, which would affect the mold closing or mold opening process.

[0037] Please refer to Figure 5As shown, in this embodiment, at least two guide bosses 23 are provided on the parting surface 14 of the right module 2, and guide grooves 15 corresponding to the guide bosses 23 are provided on the parting surface 14 of the left module 1, and the guide bosses 23 are embedded in the guide grooves 15. The guide bosses 23 guide and position the mold closing position of the right module 2 and the left module 1, ensuring the accuracy of the mold closing position between the right module 2 and the left module 1, thereby ensuring the accuracy of the fitting position between the end of the jaw guard insert 31 and the second clearance groove 21. In this embodiment, the number of the guide bosses 23 and the guide grooves 15 are both four, and the four guide bosses 23 and the guide grooves 15 are respectively distributed at the four corners of the parting surface 14. The right module 2 and the left module 1 are guided in multiple directions to further ensure the accuracy of the mold closing position of the two.

[0038] In this embodiment, the right module 2 is provided with a mounting channel 24, into which one end of the guide boss 23 is embedded. A connecting rod 25 is disposed within the mounting channel 24, the end of which is fixedly connected to one end of the guide boss 23. The use of the connecting rod 25 to mount the guide boss 23 makes the guide boss 23 independent of the right module 2, facilitating the individual replacement of severely worn guide bosses 23 and reducing maintenance costs. In this embodiment, the end of the connecting rod 25 is provided with an outwardly extending threaded section 251, and one end of the guide boss 23 is provided with an inwardly recessed internal thread groove 233. The guide boss 23 and the connecting rod 25 are threadedly connected via the internal thread groove 233 and the threaded section 251.

[0039] Furthermore, the guide boss 23 includes a guide section 231 and a mounting section 232. The diameter of the guide section 231 is larger than that of the mounting section 232. The larger diameter of the guide section 231 allows the side of the guide section 231 facing the mounting section 232 to mate with the parting surface 14 of the right module 2, thereby increasing the contact area between the parting surface 14 and the guide section 231. The parting surface 14 provides forward support for the guide section 231, ensuring the stability of the guide section 231 and the accuracy of its extension direction. The mounting section 232 is embedded in the mounting channel 24 and fixedly connected to the connecting rod 25. Specifically, the internal thread groove 233 is defined at the end of the mounting section 232; the guide section 231 is embedded in the guide groove 15.

[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
