Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to an adjustable mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. The mold generally consists of two parts: the movable mold and the fixed mold (or the male mold and the female mold), which can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming.

[0003] However, existing molds all have a fixed cavity. In order to improve the efficiency of injection molding or reduce costs, multiple cavities are designed to achieve one-out-of-many injection molding. Therefore, for products that only differ in size, multiple corresponding models of molds need to be made and used, resulting in increased production costs. Utility Model Content

[0034] Example

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides an adjustable mold, including a lower mold 10 and an upper mold 20, the lower mold 10 includes a cavity plate 101 and an ejector plate 102 for ejecting the product in the cavity plate 101, the cavity plate 101 is provided with a lower mold core cavity 1011 and a lower mold core 1012 assembled and arranged in the lower mold core cavity 1011; the lower mold core 1012 includes a left module 1013 and a right module 1014 assembled in half, and at least one adjustment block 1015 arranged between the left module 1013 and the right module 1014 or on the side opposite to the assembled surface; the left module 1013 and the right module 1014 are assembled to form a lower cavity, or the left module 1013, the right module 1014 and the adjustment block 1015 are assembled to form the lower cavity. The upper mold 20 is provided with an upper mold core cavity 201, an upper mold core 202 arranged in the upper mold core cavity 201, and a limit block 203 placed or removed between the upper mold core cavity 201 and the upper mold core 202; the upper mold core 202 and the lower mold core 1012 are assembled to form an injection cavity; the width of the limit block 203 is set to be the same as the width of the adjustment block 1015, and the number of the limit blocks 203 is set to be the same as the number of the adjustment blocks 1015.

[0036] Specifically, the lower mold core 1012 can be assembled and placed in the lower mold core cavity 1011, and the size can be adjusted by the adjustment block 1015. That is, the lower mold core 1012 assembled by the left module 1013 and the right module 1014 is the smallest lower mold cavity; if the adjustment block 1015 is placed between the left module 1013 and the right module 1014, the length or width of the lower mold cavity can be increased, thereby forming an adjustment of the size specification, so different sizes can be adjusted by setting different numbers of adjustment blocks 1015. For example, two adjustment blocks 1015 are set, and the lower mold core 1012 formed by the left module 1013 and the right module 1014 is the smallest mold core; the left module 1013, the right module 1014 and the two adjustment blocks 1015 are combined to form the largest mold core; and after the left module 1013, the right module 1014 and one adjustment block 1015 are combined, the other adjustment block 1015 is located between the left module 1013 and the lower mold core cavity 1011 for limiting, thereby achieving the purpose of adjustment and limiting.

[0037] The upper mold 20 can be matched with the lower mold core 1012 by replacing the upper mold core 202, and then installed and fixed by the limit block 203. If the upper mold core 202 is completely engaged with the upper mold core cavity 201, the limit block 203 can be removed to form the injection cavity of the product, thereby achieving the effect of injection molding production.

[0038] This embodiment can be used for injection molding rectangular door panels, or other products that only need to change the length or width without affecting the design of the outer contour, such as columnar products or rectangular products. The adjustment block 1015 and the limit block 203 can be strip plates for adjustment.

[0039] Furthermore, if Figure 2 As shown, in this embodiment, the left module 1013 is provided with a vertex module 1016 assembled with itself, and there are multiple vertex modules 1016, and the first dimension of one vertex module 1016 is larger than the first dimension of another vertex module 1016; the first dimension is the length dimension corresponding to the assembled surface of the left module 1013 and the right module 1014; the right module 1014 has the same structural arrangement as the left module 1013.

[0040] For ease of explanation and understanding, the width dimension of the door panel is adjusted by the adjustment block 1015 and the limit block 203, while the top angle module 1016 adjusts the length dimension of the door panel.

[0041] Specifically, by replacing different vertex modules 1016, the length dimension of the left module 1013 can be changed. Taking two sizes as an example, one vertex module 1016 has a cavity for injection molding a door panel, while the other vertex module 1016 does not have a cavity. In this way, cavities of different length dimensions are formed by replacement. The right module 1014 is replaced in the same way. The adjustment block 1015 can be designed as a multi-section splicing structure according to the length of the vertex module 1016, so as to adapt to the splicing of the corresponding mold core cavity, and form a variety of different sizes of splicing for use, so as to adapt to door panels of different sizes and models.

[0042] Furthermore, if Figure 3 As shown, in this embodiment, the upper mold core 202 is provided with a top module 2021 assembled with itself, and multiple top modules 2021 are provided, and the second dimension of one top module 2021 is larger than the second dimension of another top module 2021; the second dimension and the first dimension are dimensions in the same direction.

[0043] The structure of the upper mold core 202 can also be designed in a splicing manner, so that the number of upper mold cores 202 can be reduced, and the cavity structure adapted to the cavity of the lower mold 10 can be spliced ​​in the length direction through the top module 2021, so that the desired size can be spliced. The design principle of the top module 2021 is the same as that of the top corner module 1016.

[0044] like Figure 1 As shown, in this embodiment, a top plate 204 is arranged on the top surface of the upper mold 20, and the top plate 204 is provided with a plurality of first injection molding pipelines 205 extending to the cavity of the upper mold core 202, and the interface of the first injection molding pipeline 205 is arranged on the side or top surface of the upper mold 20. There are a plurality of first injection molding pipelines 205, each of which is independently designed, so that injection molding materials can be independently provided to different areas. That is, there are different injection molding pipelines for the size adjustment parts, so that after the size is adjusted, the injection molding pipeline of the interface can be stopped, so as to form the effect of injection molding of different areas, so as to adapt to the injection molding method of size adjustment, and have good practicality.

[0045] like Figure 1 As shown, in this embodiment, the lower mold 10 is provided with a second injection molding pipeline 106 and an air circuit 107 extending to the cavity of the lower mold core 1012. Similarly, a corresponding injection molding pipeline and an air circuit 107 can be provided in the lower mold 10, and the air in the cavity can be discharged through the air circuit 107 to avoid bubbles. At the same time, multiple injection molding pipelines are used for injection molding, which can ensure uniform distribution of the injection molding material, reduce stress concentration, and improve practicality.

[0046] like Figure 1As shown, in this embodiment, the ejector plate 102 is provided with a cylinder 103 that drives itself to move back and forth, and the cylinder 103 is arranged on the cavity plate 101. By driving the ejector plate 102 to move by the cylinder 103, the injection molded product can be ejected from the lower mold 10, achieving the effect of automatic demolding.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, at least one lifting ring 104 is provided on the outer side surface of the lower mold 10. Since the mold is heavy as a whole, the design of the lifting ring 104 is convenient for lifting, carrying or disassembly, etc., which is convenient for operation and improves practicality.

[0048] like Figure 1 As shown, in this embodiment, the bottom surface of the lower mold 10 is provided with a bottom plate 105. The design of the bottom plate 105 of the lower mold 10 and the top plate 204 of the upper mold 20 are both used to protect the upper and lower surfaces of the mold, and at the same time, they are slightly protruding from the cavity plate 101 or the ejector plate 102 to avoid wear of the injection port or other structures, providing a protective effect.

[0049] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
