Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] As shown in the attached Figure 1 to the attached Figure 3 figure.

[0021] A canned injection mold provided by the present utility model includes a supporting bottom plate 1, a lifting push rod 2, a lifting plate 3, a lower mold assembly 4, an upper mold assembly 5 and a canned finished product 6, wherein: the lifting push rod 2 is fixedly installed on the surface of the supporting bottom plate 1, and the lifting plate 3 is fixedly installed at the top of the lifting push rod 2, and the lower mold assembly 4 is fixedly installed on the surface of the lifting plate 3; the upper mold assembly 5 is fixedly installed outside the supporting bottom plate 1 and is located above the lower mold assembly 4; the canned finished product 6 is formed between the lower mold assembly 4 and the upper mold assembly 5.

[0022] The lower mold assembly 4 includes a slide bar support frame 41, slide bars 42, a split lower mold 43, a push rod support 44, and push rods 45. The slide bar support frame 41 is fixedly installed on the surface of the lifting plate 3, and the slide bars 42 are fixedly installed between the slide bar support frames 41. The split lower mold 43 is slidably installed on the slide bars 42, and the push rod support 44 is fixedly installed on the surface of the lifting plate 3, outside the slide bar support frame 41. The push rods 45 are fixedly installed between the split lower mold 43 and the push rod support 44.

[0023] The upper mold assembly 5 includes a support framework 51, an upper mold support plate 52, an upper mold 53, and an injection hole 54. The support framework 51 is fixedly installed outside the support base plate 1. The upper mold support plate 52 is fixedly installed in the middle of the support framework 51, and the upper mold 53 is fixedly installed below the upper mold support plate 52. The injection hole 54 is formed inside the upper mold support plate 52 and the upper mold 53.

[0024] Two sets of split lower molds 43 are used inside the lower mold assembly 4, and the split lower molds 43 are mirror images of each other. The split lower molds 43 can be driven by the push rods 45 to approach and move away from each other. A complete mold can be formed between the split lower molds 43. The split lower molds 43 can move vertically through the movement of the lifting plate 3 and can wrap the upper mold 53 when moving upward.

[0025] The entire upper mold assembly 5 cannot move, and the upper mold 53 can form a complete can-shaped mold when the split lower molds 43 move to its outside.

[0026] The can body injection mold is a device that heats, injects plastic materials, and cools them in the mold to form can-shaped products. The working principle of this injection mold mainly includes the following steps:

[0027] 1. Mold preparation

[0028] The upper and lower mold assemblies of the mold need to be fixed and debugged in advance. The lower mold assembly 4 is installed on the lifting plate 3 and is adjusted in height through the lifting push rod 2. The upper mold assembly 5 is fixedly installed outside the support base plate 1 to ensure its stability during the entire molding process. The injection material is injected through the injection hole 54 of the upper mold assembly 5 and gradually fills the mold cavity.

[0029] 2. Adjustment of the lifting plate

[0030] Before injection molding starts, the lifting push rod 2 pushes the lifting plate 3 downward so that the lower mold assembly 4 is in a lower position, facilitating the removal of the finished product from the mold or the installation of a new mold structure. According to the size requirements of the mold and the product, the height of the lifting plate 3 can be freely adjusted to ensure the tight fit between the upper and lower mold assemblies.

[0031] 3. Molding process

[0032] During the injection molding process, the molten plastic material is injected into the upper mold assembly 5 through the injection hole 54, and the injection material fills the cavity between the lower mold assembly 4 and the upper mold assembly 5 through the injection hole. The split lower mold 43 can slide on the slide rod 42 through the action of the push rod 45, thereby adjusting the closing state of the mold to ensure that the plastic material evenly fills the mold.

[0033] 4. Mould closing and pressurization

[0034] After the injection molding material is injected into the mold cavity, the split lower mold 43 approaches each other and completely wraps the upper mold 53 to form a complete mold cavity. The closure of the mold ensures that the injection molding material is forced to fill every corner of the mold under high pressure, thereby forming the shape of the can body.

[0035] 5. Cooling and solidification

[0036] After the plastic material fills the mold, the cooling process begins. Cooling channels in the mold or an external cooling system help quickly cool and solidify the molten plastic. This process determines the shape and mechanical properties of the finished product. As the temperature drops, the can-shaped finished product 6 gradually takes shape in the mold.

[0037] 6. Demolding and removal

[0038] When the can body is formed and completely solidified, the lifting push rod 2 is started again, pushing the lifting plate 3 and the lower mold assembly 4 on it upward, and the split lower mold 43 is opened by the action of the push rod 45, so that the finished product is separated from the mold, and the operator or automatic device takes the can-shaped finished product 6 out of the mold.

[0039] 7. Mold reset

[0040] After the finished product is taken out, the mold automatically resets, and the lower mold assembly 4 is closed again under the push of the push rod 45, ready for the next injection cycle. The upper mold assembly 5 remains in a fixed position and continues to cooperate with the lower mold for the next round of molding.

[0041] Summarize

[0042] The tank body injection mold achieves a precise tank body molding process through the flexible adjustment of the lifting system and the split lower mold. The injection material is injected from the upper mold and formed into a can-shaped product under pressure and cooling conditions through the cooperation of the upper and lower molds. The lifting and separation mechanism of the mold ensures that the finished product can be removed smoothly, improving production efficiency and ensuring the quality of the finished product.

[0043] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
