Technical Field

[0001] This utility model relates to the field of inner sleeve molds, specifically an inner sleeve mold for a curling iron. Background Technology

[0002] A curling iron inner sleeve typically refers to a heat-insulating sleeve for curling irons, usually made of heat-insulating material. It covers the heating element after use to prevent burns from accidental contact with the hot rod. When not in use, it also protects the curling iron from dust. Some inner sleeves are even designed for portability and easy storage.

[0003] The inner sleeve of a curling iron is usually made of silicone and needs to be molded using a processing mold. However, the current curling iron inner sleeve mold usually ejects the molded product after molding. Since the product is attached to the molding mold, it is difficult to eject the product and it is not convenient to demold the molded product.

[0004] Therefore, a curling iron inner sleeve mold is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an inner sleeve mold for curling irons.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A curling iron inner mold of this utility model includes a first lower mold; a second lower mold is installed on the top of the first lower mold, a third lower mold is installed on the top of the second lower mold, a first upper mold is installed on the top of the third lower mold, a first electric push rod is installed on the top of the second lower mold, a second upper mold is installed on the top of the first electric push rod, a third upper mold is installed on the bottom of the second upper mold, an injection mold is installed inside the third upper mold, a second electric push rod is installed on the bottom of the second upper mold, and the bottom of the second electric push rod is connected to the first upper mold. A molding base is installed on the top of the lower mold, and a molding mold is installed on the top of the third lower mold. A guide block is installed on the inner side of the first upper mold, and the guide block is slidably connected to the molding mold. A molded product is disposed on the inner side of the guide block. An ejector rod is installed inside the third lower mold, and the ejector rod passes through the molding base. In this step, the material is molded by injection molding into the inside of the molding mold through the up-and-down moving injection mold. By driving the first upper mold to move up and down, the inner molding mold can be driven to close and open when the first upper mold moves, thus molding the injection material and separating it from the molded product. With the help of the ejector rod at the bottom, the molded product is easily ejected.

[0007] Preferably, the third lower mold has a guide groove inside, and the bottom of the forming mold is equipped with a positioning rod, which is located inside the guide groove; this step allows the forming mold to move along the direction of the guide groove, increasing the stability of the forming mold when it moves around.

[0008] Preferably, a first connecting block is installed on the top of the third lower mold, and a second connecting block is installed on the bottom of the first upper mold; in this step, when the first connecting block is attached to the first upper mold, the first connecting block is connected to the second connecting block, which increases the stability when the first upper mold and the third lower mold are attached.

[0009] Preferably, a limiting block is installed on the top of the third lower mold, and the side of the limiting block is in contact with the forming mold; this step can limit the movement trajectory of the forming mold by the limiting block, thereby increasing the stability of the forming mold when it moves on the top of the third lower mold.

[0010] Preferably, both the third lower mold and the first upper mold have several heat dissipation pipes on their sides; this step can reduce the temperature of the third lower mold and the first upper mold after injection molding, so that the molded product can be formed faster.

[0011] Preferably, the top of the first upper mold is provided with a connecting groove, and the side of the connecting groove is provided with a bevel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7As shown, a curling iron inner mold includes a first lower mold 1; a second lower mold 12 is mounted on the top of the first lower mold 1; a third lower mold 13 is mounted on the top of the second lower mold 12; a first upper mold 14 is mounted on the top of the third lower mold 13; a first electric push rod 15 is mounted on the top of the second lower mold 12; a second upper mold 16 is mounted on the top of the first electric push rod 15; a third upper mold 17 is mounted on the bottom of the second upper mold 16; an injection mold 18 is installed inside the third upper mold 17; and a second electric push rod 19 is mounted on the bottom of the second upper mold 16. The bottom of mold 19 is connected to the first upper mold 14. A molding base 110 is installed on the top of the third lower mold 13, and a molding mold 111 is installed on the top of the third lower mold 13. A guide block 112 is installed on the inner side of the first upper mold 14, and the guide block 112 is slidably connected to the molding mold 111. A molded product 113 is provided on the inner side of the guide block 112. A push rod 114 is installed inside the third lower mold 13, and the push rod 114 passes through the molding base 110. During operation, raw material is injected into the injection mold 18 through the injection port at the top of the second upper mold 16, and the raw material enters the molding mold 111. The material is then deposited on the side and solidified. The first electric push rod 15 pushes the second upper mold 16 upwards, which in turn moves the third upper mold 17 and the second electric push rod 19. The third upper mold 17 then moves the injection mold 18, causing its bottom to separate from the inner side of the forming mold 111. The second electric push rod 19 then moves the first upper mold 14, which in turn moves the guide block 112. When the guide block 112 moves upwards, the connecting slide rail between the guide block 112 and the forming mold 111 causes multiple forming molds 111 to move simultaneously outwards, thus... The inner side of the molding mold 111 separates from the molded product. Then, the ejector rod 114 moves upward, pushing the top of the molding base 110 upward to separate it from the molding mold 111. This step involves injection molding of the inside of the molding mold 111 by the injection mold 18, which moves up and down, to mold the material. By driving the first upper mold 14 to move up and down, the first upper mold 14 can drive the inner molding mold 111 to close and open, molding the injected material and separating it from the molded product. With the help of the ejector rod 114 at the bottom, the molded product 113 is easily ejected.

[0026] like Figure 5 and Figure 6 As shown, the third lower mold 13 has a guide groove 21 inside, and the bottom of the forming mold 111 is equipped with a positioning rod 22, which is located inside the guide groove 21. During operation, when the forming mold 111 moves, it drives the positioning rod 22 to slide inside the guide groove 21. This step allows the forming mold 111 to move along the direction of the guide groove 21, increasing the stability of the forming mold 111 when it moves around.

[0027] like Figures 1 to 4 As shown, a first connecting block 31 is installed on the top of the third lower mold 13, and a second connecting block 32 is installed on the bottom of the first upper mold 14. During operation, when the first upper mold 14 moves, it drives the second connecting block 32 to move. When the first upper mold 14 and the third lower mold 13 are in contact, the first connecting block 31 and the second connecting block 32 are connected. This step, where the first connecting block 31 and the first upper mold 14 are in contact, increases the stability when the first upper mold 14 and the third lower mold 13 are in contact.

[0028] like Figure 6 As shown, a limiting block 41 is installed on the top of the third lower mold 13, and the side of the limiting block 41 is in contact with the forming mold 111. During operation, when the forming mold 111 moves, it slides along the limiting blocks 41 on both sides of the forming mold 111. This step can limit the movement trajectory of the forming mold 111 through the limiting block 41, increasing the stability of the forming mold 111 when it moves on the top of the third lower mold 13.

[0029] like Figure 1 As shown, several heat dissipation pipes 51 are provided on the sides of the third lower mold 13 and the first upper mold 14. During operation, after the injection mold 18 injects the inner side of the molding mold 111, the external water source can be connected to the heat dissipation pipes 51 to dissipate heat to the inner side of the third lower mold 13 and the first upper mold 14. This step can reduce the temperature of the third lower mold 13 and the first upper mold 14 after injection molding, so that the molded product 113 can be molded faster.

[0030] like Figure 4 As shown, the top of the first upper mold 14 is provided with a connecting groove 61, and the side of the connecting groove 61 is provided with a bevel. During operation, after the injection mold 18 enters the connecting groove 61, it can perform injection molding on the inside of the molding mold 111. This step can limit the injection mold 18 through the connecting groove 61, increasing the stability of the injection mold 18 when injecting into the inside of the molding mold 111. The bevel can reduce the friction when the injection mold 18 enters the connecting groove 61.

[0031] Working principle: Raw material is injected into the injection mold 18 through the injection port at the top of the second upper mold 16. The raw material enters the inner side of the molding mold 111 and then solidifies. The first electric push rod 15 pushes the second upper mold 16 upward, which in turn moves the third upper mold 17 and the second electric push rod 19. The third upper mold 17 then moves the injection mold 18, causing the bottom of the injection mold 18 to separate from the inner side of the molding mold 111. When the molding mold 111 moves, it causes the positioning rod 22 to slide inside the guide groove 21. The second electric push rod 19 then moves the second upper mold 18. When the upper mold 14 moves, the guide block 112 and the second connecting block 32 move through the upper mold 14. When the guide block 112 moves upward, the connecting slide rail between the guide block 112 and the forming mold 111 drives multiple forming molds 111 to move outward at the same time, so that the inner side of the forming mold 111 separates from the formed product. Then the ejector rod 114 moves upward and pushes the top of the forming base 110 upward, so that it separates from the forming mold 111. When the second connecting block 32 moves, when the upper mold 14 and the lower mold 13 are in contact, the first connecting block 31 connects with the second connecting block 32.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
