[0002] In the mold industry, various molds and tools are used to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material, and is known as the "mother of industry".

[0003] When using a mold for casting and molding, the molten metal solution will be poured into the mold cavity in the mold. However, the mold cavity size of the existing mold is fixed and the space size of the injection mold cavity in the mold cannot be adjusted at will. This will lead to greater limitations when the mold is used in different situations. If the same object of different heights needs to be injection molded, many molds need to be replaced to complete the injection molding of the object, which increases financial expenditure and is more troublesome to replace the mold.

[0004] Therefore, it is particularly important to improve the existing mold cavity height adjustment device and mold, design a new mold cavity height adjustment device and mold to solve the above-mentioned technical defects, and improve the practicability of the overall mold cavity height adjustment device and mold.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A mold cavity height adjustment device comprises a mold cavity 1 and an inner mold 2. A height adjustment component 3 is installed outside the mold cavity 1.

[0025] The height adjustment assembly 3 is used for adjusting the height of the inner mold 2 .

[0026] For further information, see Figure 1 and Figure 2 In this embodiment, the height adjustment component 3 includes an upper connecting plate 301, a lower connecting plate 302, a first connecting rod 303, a second connecting rod 304 and a moving block 305. The upper connecting plate 301 and the lower connecting plate 302 are both located on the outside of the mold cavity 1, the first connecting rod 303 and the second connecting rod 304 are both located between the upper connecting plate 301 and the lower connecting plate 302, and the moving block 305 is located inside the first connecting rod 303. By unfolding the first connecting rod 303 and the second connecting rod 304, the first connecting rod 303 and the second connecting rod 304 are moved away from each other, so that the moving block 305 at one end of the first connecting rod 303 and the second connecting rod 304 is close to each other.

[0027] Among them, see Figure 1 and Figure 2 In this embodiment, a thread groove is provided inside the moving block 305, a screw rod 306 is installed inside the thread groove, and the moving block 305 is threadedly connected to the outside of the screw rod 306. By rotating the screw rod 306, the moving block 305 can move away from and closer to each other outside the screw rod 306.

[0028] Second, see Figure 1 and Figure 2 In the present embodiment, one end of the first connecting rod 303 is rotationally connected to the lower connecting plate 302, the end of the first connecting rod 303 away from the lower connecting plate 302 is rotationally connected to the moving block 305, one end of the second connecting rod 304 is rotationally connected to the upper connecting plate 301, and the end of the second connecting rod 304 away from the upper connecting plate 301 is rotationally connected to the outside of the second connecting rod 304. Through the rotational connection between the first connecting rod 303 and the second connecting rod 304, when the moving block 305 moves away from and towards each other, the first connecting rod 303 and the second connecting rod 304 drive the upper connecting plate 301 away from the lower connecting plate 302.

[0029] Furthermore, please see Figure 1 and Figure 2 In this embodiment, a fixing rod 307 is installed on the outside of the upper connecting plate 301, a connecting rod is installed between the fixing rod 307 and the upper connecting plate 301, and a fixing plate 308 is installed on the bottom of the lower connecting plate 302. When the upper connecting plate 301 rises, the fixing rod 307 is driven to rise through the connecting rod, and the stability of the lower connecting plate 302 is improved through the fixing plate 308.

[0030] For further information, see Figure 1 and Figure 4 In this embodiment, a fixed seat 4 is symmetrically installed on the front and rear sides of the mold cavity 1, and a sliding rod 5 is installed inside the fixed seat 4. A limiting sleeve 6 is installed on the top and bottom of the sliding rod 5. The upper connecting plate 301 rises, thereby driving the sliding rod 5 to gradually rise inside the fixed seat 4, and the sliding rod 5 is separated from the inside of the fixed seat 4 by the limiting sleeve 6.

[0031] The utility model also provides a mold, which is applied to the mold cavity height adjustment device in the above embodiment, and also includes:

[0032] The upper mold 7 and the lower mold 8, the height adjustment component 3 is located between the upper mold 7 and the lower mold 8, the inner mold 2 is located inside the upper mold 7 and inside the mold cavity 1, and a feed port 9 is opened on the top of the upper mold 7. By entering the plastic from the feed port 9, the plastic flows into the mold cavity 1 through the inner mold 2, thereby performing injection molding.

[0033] In this embodiment, the implementation scenario is specifically as follows: by allowing plastic to enter from the feed port 9, the plastic flows into the interior of the mold cavity 1 through the inner mold 2, thereby performing injection molding, and by rotating the screw rod 306, the movable block 305 moves away from each other outside the screw rod 306, so that the first connecting rod 303 and the second connecting rod 304 move away from each other, so that the upper connecting plate 301 completes the rising work, and the fixing rod 307 is driven to rise by the connecting rod, so that the sliding rod 5 can slide on the fixed seat 4, and the height adjustment between the upper mold 7 and the lower mold 8 can be achieved, so that the inner mold 2 rises inside the mold cavity 1, thereby achieving the purpose of adjusting the height of the mold cavity 1 and the inner mold 2, so that the same mold can be used to inject the same type of objects of different heights, which greatly reduces financial expenditures, and does not require the replacement of different molds, making it more convenient to use.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
