Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a female mold forming mold. Background Art

[0002] During the thermoforming process, only one side of the heated material contacts the forming mold, so that the surface of the material in contact with the mold has the same surface profile as the forming mold. According to the difference in the contact surface between the forming material and the forming mold, the forming mold can be divided into a male mold and a female mold. For the male mold, the inner surface of the forming material contacts the mold, while for the female mold, the outer surface of the forming material contacts the mold.

[0003] When processing C-frame parts, the assembly surface is the outer surface of the part. When using a male mold to make C-frame parts, the assembly surface needs to be processed twice to ensure the subsequent assembly accuracy. However, it is easy to cause the surface fiber of the part to break during the processing, which reduces the service life of the part. Therefore, most C-frame parts are processed using a female mold. However, whether it is a female mold or a male mold, it is easy to damage the part during demoulding. Utility Model Content

[0036] See also Figure 1 and Figure 2, the female mold forming mold provided in this embodiment is specifically used by first placing the embedded body 3 in the margin area of ​​the mold body 1, and then laying the molding material 100 on the mold body 1, and performing a curing treatment to make the molding material 100 fit with the mold body 1. After the curing is completed, the adjusting rod 2 is moved so that the end of the adjusting rod 2 passes through the embedded body 3 and abuts against the mold body 1, so that the mold body 1 is subjected to force and detaches from the embedded body 3 to achieve demolding; finally, the material at the position of the molding material 100 corresponding to the margin area is cut off, so as to obtain a part with the same shape as the molding cavity 11.

Demolding can be achieved by moving the adjusting rod 2, and the operation is very convenient. The embedded body 3 is arranged in the margin area, and the force-bearing area during demolding is located in the margin area, which will not cause damage to the parts and ensure the molding quality of the parts.

[0037] It should be noted that the female mold provided in this embodiment is not limited to the hot forming processing of C-shaped frame parts, but can also be applied to the hot forming processing of parts of other shapes, and it is only necessary to change the shape of the molding cavity 11. Furthermore, in order to facilitate demoulding, the molding cavity 11 needs to be set with a certain draft angle. The setting of the draft angle belongs to the prior art and is not described in detail in this embodiment.

By moving the adjusting rod 2, the end of the adjusting rod 2 away from the connecting plate 41 can be inserted into the embedded body 3 and abut against the mold body 1, so that the mold body 1 is separated from the embedded body 3 and demoulding is achieved. The setting of a plurality of spaced connecting rods 42 ensures the stability of the connection between the connecting plate 41 and the embedded body 3, and ensures the uniformity of the force on the mold body 1 during demoulding.

[0039] Preferably, a threaded hole is provided on the connecting plate 41, and the adjusting rod 2 is screwed to the connecting plate 41 through the threaded hole. The threaded connection method can drive the adjusting rod 2 to move by screwing the adjusting rod 2, which is very convenient. In this embodiment, the threaded hole is provided at the center of the connecting plate 41, and 4 connecting rods 42 are provided, which are respectively located at the four corners of the connecting plate 41. Furthermore, a mounting hole is provided on the connecting plate 41, and the mounting hole includes a large diameter section and a small diameter section that are connected. A hexagonal nut is embedded in the large diameter section, so that the hexagonal nut is limited to the connecting plate 41, and the screw hole of the hexagonal nut is the above-mentioned threaded hole. Preferably, a screwing portion 21 is provided at one end of the adjusting rod 2 away from the embedded body 3, and the screwing portion 21 can be convenient for the user to hold, so that the adjusting rod 2 can be screwed through the screwing portion 21, which is convenient for operation.

Furthermore, a stopper 421 is provided at one end of the connecting rod 42 away from the connecting plate 41, and the stopper 421 can limit the connecting rod 42 in the first through hole 31. The provision of the stopper 421 can prevent the connecting rod 42 from being separated from the embedded body 3.

[0043] Furthermore, the stopper 421 and the first through hole 31 are both configured as strips. When the stopper 421 is parallel to the first through hole 31, the connecting rod 42 can pass through the first through hole 31. When the stopper 421 is perpendicular to the second through hole 31, the connecting rod 42 can be limited in the first through hole 31. When connecting, firstly, the stopper 421 is parallel to the first through hole 31 to insert the connecting rod 42 into the first through hole 31. Then, the connecting rod 42 is rotated to make the stopper 421 perpendicular to the first through hole 31 to limit the connecting rod 42 in the first through hole 31. The installation is very convenient. After demoulding is completed, the connecting rod 42 is rotated again to make the stopper 421 parallel to the first through hole 31. Then, the connecting rod 42 can be removed from the embedded body 3, thereby removing the molding material 100 after curing. Then, part of the residual area is cut off to obtain a molded part.
