Technical Field

[0001] This utility model belongs to the field of mold equipment and relates to a mold with adjustable cavity depth. Background Technology

[0002] Existing PU sheet molding molds typically have a cavity in the lower mold where liquid material is injected for foaming to obtain PU parts. To mold PU parts of different thicknesses, the current method is to add a gasket in the mold cavity when a thinner PU part is required. However, the gasket is relatively heavy, inconvenient to assemble, and also expensive. Summary of the Invention

[0003] In order to overcome at least one deficiency of the prior art, this utility model provides a mold with adjustable cavity depth.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a mold with adjustable cavity depth, comprising an upper mold, a lower mold, and a depth adjustment structure located between the two, wherein the depth adjustment structure is disposed on the lower mold, and the depth adjustment structure includes at least a set of depth components, the depth components forming a mold cavity with the upper mold and the lower mold.

[0005] Furthermore, the depth component has a through cavity, with the upper mold and lower mold located on both sides of the through cavity, and the through cavity, together with the upper surface of the lower mold and the lower surface of the upper mold, forms a mold cavity.

[0006] Furthermore, the thickness of the depth adjustment structure is the thickness of a group of depth components or the thickness of a stack of several depth components, and the thickness of the depth adjustment structure is the thickness of the PU part.

[0007] Furthermore, the depth component is designed as a split structure, comprising at least two sets of pads, with several pads connected end to end to form the depth component.

[0008] Furthermore, the depth adjustment structure also includes several limiting members, which are fixed on the surface of the lower mold and located outside the depth assembly.

[0009] Furthermore, the thickness of the limiting member matches the thickness of the PU part.

[0010] Furthermore, the two sets of limiting members are located on the outer sides of both ends of a set of pads.

[0011] Furthermore, the depth component is designed as a single, integrated structure.

[0012] Furthermore, the depth component is made of metal.

[0013] In summary, the advantages of this utility model are as follows:

[0014] 1) This utility model obtains mold cavities of different depths by using components of different thicknesses or by stacking components of different depths, thereby obtaining PU parts of different thicknesses. Compared with conventional solutions, the pads are easy to assemble and can freely obtain different thicknesses.

[0015] 2) The split-type depth component of this utility model can be assembled to obtain PU parts of different thicknesses, and the depth component is made of metal, which can effectively save materials and reduce costs.

[0016] 3) This utility model restricts the depth component on the outside by using several limiting members, thereby ensuring the accuracy of the installation position of the depth adjustment structure and further reducing the gap between adjacent pads. Attached Figure Description

Detailed Implementation

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0021] Example 1:

[0022] like Figures 1-3 As shown, a mold with adjustable cavity depth includes an upper mold 1, a lower mold 2, and a depth adjustment structure 3 located between the two. The depth adjustment structure 3 is disposed on the lower mold 2 and includes at least a set of depth components 32. The depth components 32 are configured to be connected end to end, and the depth components 32, the upper mold 1, and the lower mold 2 form a mold cavity.

[0023] The depth component 32 is fixedly connected to the lower mold 2. The connection between the two can be achieved by conventional fastening methods such as screws or bolts, which will not be elaborated here.

[0024] The depth component 32 is designed as a ring structure with a through cavity 320 running vertically through it. The shape of the through cavity 320 matches the shape of the PU part. When the depth adjustment structure 3 includes a set of depth components 32, the upper mold 1 and the lower mold 2 are located on both sides of the through cavity 320. The through cavity 320, the upper surface of the lower mold 2, and the lower surface of the upper mold 1 form a mold cavity. When molding is required, liquid material is injected into the mold cavity for foaming to obtain the PU part. At this time, the thickness of the depth adjustment structure 3 is the thickness of the depth component 32, and the thickness of the depth component 32 is the thickness of the PU part. When it is necessary to mold PU parts of different thicknesses, the depth components 32 of different thicknesses can be replaced. When the depth adjustment structure 3 includes several sets of depth components 32, along the thickness direction ( Figure 1 As shown by the arrow, the stacked arrangement of the depth adjustment structures 3 and the adjacent depth adjustment structures 3 are fixedly connected and the through cavities 320 are interconnected. The upper depth adjustment structure 3 is in contact with the upper mold 1, and the lower depth adjustment structure 3 is fixedly connected with the lower mold 2. The through cavities 320, the upper surface of the lower mold 2, and the lower surface of the upper mold 1 form a mold cavity. At this time, the thickness of the depth adjustment structure 3 is the thickness of the stacked depth components 32. The thickness of the depth adjustment structure 3 is the thickness of the PU part. The thickness of the depth components 32 included in the depth adjustment structure 3 can be the same or different, and can be selected according to actual needs.

[0025] This embodiment obtains mold cavities of different depths by using components 32 of different thicknesses or by stacking components 32, thereby obtaining PU parts of different thicknesses. Compared with conventional solutions, the pads are easy to assemble and can freely obtain different thicknesses.

[0026] The depth component 32 is designed as a split structure, including at least two sets of pads 321, such as... Figure 1 As shown, the depth component 32 includes four sets of pads 321. The pads 321 are designed as straight rods, and the four sets of pads 321 are connected end to end to form a square ring structure. In other embodiments, the pads 321 can also be designed as bent structures, and the two sets of pads 321 are connected end to end to form a square ring structure. Or the number of pads 321 can be more or less to form the depth component 32. Or the depth component 32 can also be designed as a circular ring or other regular or irregular shapes. The technical solution of this embodiment is also applicable.

[0027] The depth component 32 is made of metal, preferably aluminum.

[0028] In this embodiment, the pad strip 321 forms a depth component 32 with an annular structure. During processing, the pad strip 321 is subjected to conventional annealing to relieve stress, prevent stress concentration, and avoid deformation.

[0029] In this embodiment, the split depth component 32 is assembled to obtain PU parts of different thicknesses, and the depth component 32 is made of metal, which can effectively save materials and reduce costs.

[0030] In this embodiment, the metal strips 321 are tightly connected, which can reduce the gap between adjacent strips 321 and effectively prevent material leakage. Further spraying of release agent fills the gap to prevent material leakage.

[0031] Furthermore, to ensure the accuracy of the stacked installation of several depth components 32 and the installation position of the split depth components 32, the depth adjustment structure 3 also includes several limiting members 31. The limiting members 31 are fixed to the surface of the lower mold 2 and located outside the depth components 32. The thickness of the limiting members 31 is consistent with the thickness of the PU part. These limiting members 31 restrict the depth components 32 on the outside, thereby ensuring the accuracy of the installation position of the depth adjustment structure 3 and further reducing the gap between adjacent pads 321. To ensure the stability of the limiting of the depth components 32, such as... Figures 2-3 As shown, the two sets of limiting members 31 are located on the outer sides of both ends of a set of pads 321, that is, the set of pads 321 is limited by the two sets of limiting members 31 at both ends.

[0032] The limiting component 31 limits the depth component 32 on the outside of the periphery to prevent the depth component 32 from shifting in the horizontal direction. The depth component 32 will not shift in the vertical direction due to the action of the upper mold 1 and the lower mold 2.

[0033] The shape of the limiting member 31 can be a straight rod structure, a bent structure, etc.

[0034] This embodiment does not make any improvements to the structure of the upper mold 1 and the lower mold 2. Other structures not mentioned in either mold adopt the existing design. The depth adjustment structure 3 is also applicable to the existing upper mold 1 and lower mold 2.

[0035] Example 2:

[0036] The difference between this embodiment and the above embodiments is that in embodiment one, the depth component 32 is a split structure, while in this embodiment, the depth component 32 is a one-piece structure.

[0037] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
