Description

Technical Field

[0001] This utility model relates to a preparation mold for a leveling component, and more particularly to a preparation mold for a leveling component used in hinge assemblies. Background Technology

[0002] Existing hinges mainly consist of a hinge head, a hinge arm, and a base. During installation, the hinge head and base are installed sequentially onto the cabinet door and cabinet body, respectively. Because the hinge's structure for adjusting the installation position is simple, it is difficult to meet usage requirements. Therefore, most existing hinges require high installation and positional accuracy. When the installation position deviates, the cabinet door and cabinet body cannot be installed in the intended position, increasing installation difficulty, extending the work cycle, and reducing work efficiency. To address this, some hinges are equipped with adjustment devices. The hinge arm can be adjusted relative to the base via these devices to achieve vertical, horizontal, or lateral adjustments, thereby reducing the requirements for installation and positional accuracy. However, the existing hinges' vertical and horizontal height adjustments relative to the base are mutually dependent. For example, the height adjustment screw can only adjust the front end of the base upwards or downwards. When the front end of the base is adjusted upwards to the designated position, it tilts backwards, forming an angle with the hinge arm. This can be understood as the angle between the base and the hinge arm changing during adjustment. Consequently, the cabinet door may not close completely or smoothly relative to the cabinet body, resulting in a gap between the closed side of the door and the cabinet body. Therefore, adjusting the front and rear adjustment screws of the base and hinge arm is necessary to ensure the cabinet door is installed in the intended position. This leads to frequent errors in height and front / rear adjustments of the base and hinge arm, making adjustment difficult.

[0003] To address this challenge, Chinese Patent Publication No. CN220909428U discloses a hinge assembly for furniture, comprising a first body, a hinge head, and a base device. The base device includes at least one first adjustment component and at least one second adjustment component. The first adjustment component has at least one first adjustment part. When the first adjustment part is adjusted alone, the first body can move vertically relative to the first adjustment component only in the vertical direction, thus enabling the first body to move vertically relative to at least a portion of the base device only in the vertical direction. The second adjustment component has a second adjustment part. When the second adjustment part is adjusted alone, the first body can move vertically relative to at least a portion of the base device only in the forward and backward direction. Specifically, the first adjustment component includes a fourth body (i.e., a leveling member). The fourth body has an adjustment hole for connecting to the first adjustment part. In some embodiments, to ensure the strength of the adjustment hole, the fourth body also has a recessed reinforcing part at the position corresponding to the adjustment hole. Furthermore, referring to Figures 56 and 60 of this patent document, when the distance between the first left side plate and the first right side plate is closer to the width distance of the reinforcing part, the less material is used in the fourth body and the lower the cost. However, when the fourth body has the structure shown in Figures 56 and 60 of this patent document (i.e., a portion of the reinforcing part is formed on the first left side plate and the first right side plate), the reinforcing part... During the stamping process, the structure of the first left and right side plates is affected, causing deformation of the first left and right side plates. This necessitates an additional cutting process for the first left and right side plates to make their lower ends flush, increasing processing difficulty and reducing the production efficiency of the fourth main body. Furthermore, as shown in Figure 6, when holes need to be drilled in the first left and right side plates of the fourth main body, to ensure precise alignment of the holes, the holes can only be drilled after the first left and right side plates have been bent and formed. This results in high processing difficulty and low processing efficiency for the fourth main body.

[0004] Therefore, it is necessary to provide a technical solution to this problem. Utility Model Content

[0005] To address the issues that the reinforcing part of existing leveling parts affects the structure of the first left side plate and the first right side plate during the forming process, thus requiring the addition of a final cutting process for the first left side plate and the first right side plate, and that the holes on the first left side plate and the first right side plate can only be processed after the first left side plate and the first right side plate are bent and formed, resulting in high processing difficulty and low processing efficiency for the leveling parts, this utility model provides a preparation mold for leveling parts.

[0006] The objective of this application is achieved through the following technical solution:

[0007] A mold for preparing a leveling component includes an upper mold assembly and a lower mold assembly, wherein a first forming module, a second forming module, and a third forming module are formed on the upper mold assembly and the lower mold assembly, respectively, and they cooperate with each other.

[0008] The first forming module is used to stamp a recessed reinforcing part on the strip when the upper mold assembly and the lower mold assembly are closed;

[0009] The second forming module is used to stamp at least two mounting holes on the strip when the upper mold assembly and the lower mold assembly are closed, and the at least two mounting holes are distributed on both sides of the reinforcing part;

[0010] The first forming module and the second forming module are both located before the third forming module. The third forming module is used to punch and bend a left side plate and a right side plate that are in contact with both sides of the reinforcing part on the strip when the upper mold assembly and the lower mold assembly are closed. At least two mounting holes are formed on the left side plate and the right side plate respectively.

[0011] In some embodiments, the third forming module includes a support portion formed on the lower mold assembly and two stamping portions formed on the upper mold assembly; when the mold is closed, the two stamping portions are located on both sides of the support portion.

[0012] In some embodiments, the lower mold assembly forms clearance portions on both sides of the support portion, and the clearance portions extend through the lower mold assembly on the side away from the first molding module.

[0013] In some embodiments, the leveling part preparation mold further includes a fourth forming module, which is located after the first forming module and the second forming module and before the third forming module. The third forming module is used to punch out material distribution parts on both sides of the material strip when the upper mold assembly and the lower mold assembly are closed.

[0014] In some embodiments, the width of both the front and rear sides of the material distribution section corresponding to the position of the left side plate is not less than the width of the left side plate.

[0015] In some embodiments, the width of both the front and rear sides of the material distribution section corresponding to the position of the right side plate is not less than the width of the right side plate.

[0016] In some embodiments, the mounting hole includes a first hole and a second hole that are connected to each other, and the second forming module includes a first punch for forming the first hole on the strip and a second punch for forming the second hole on the strip.

[0017] In some embodiments, the leveling part preparation mold further includes a positioning module, the positioning module including a third punch for stamping a positioning hole on the strip when the upper mold assembly and the lower mold assembly are closed, and a positioning punch for being placed in the positioning hole when the upper mold assembly and the lower mold assembly are closed.

[0018] Compared with the prior art, the advantages of the leveling component preparation mold of this utility model are as follows:

[0019] The stamping and bending process of the left and right side plates is set after the stamping and forming process of the reinforcing part and mounting holes. This ensures that the structure of the formed left and right side plates is not affected by the structure of the reinforcing part, allowing the leveling part to be directly stamped on the leveling part preparation mold. That is, the lower end faces of the stamped left and right side plates are flush or nearly flush, and the positions of the mounting holes on the left and right side plates are also corresponding. After the leveling part is removed from the mold, no additional processing steps are required for the leveling part, reducing the difficulty of leveling part preparation and improving the production efficiency of leveling part.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In the description of the embodiments of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the embodiments of this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0034] The existing leveling parts suffer from several drawbacks. The reinforcing portion affects the structure of the first left and right side plates during molding, necessitating additional cutting of these plates at the end. Furthermore, the holes on the first left and right side plates can only be processed after bending and shaping, leading to high processing difficulty and low efficiency. This invention provides a mold for preparing a leveling part. (Refer to...) Figures 1-4 The mold for preparing the leveling component includes an upper mold assembly and a lower mold assembly, on which a first molding module 1, a second molding module 2 and a third molding module 3 are formed to cooperate with each other;

[0035] The first forming module 1 is used to stamp out a recessed reinforcing part 101 on the strip 100 when the upper mold assembly and the lower mold assembly are closed;

[0036] The second forming module 2 is used to stamp at least two mounting holes 102 on the strip 100 when the upper mold assembly and the lower mold assembly are closed. The at least two mounting holes 102 are distributed on both sides of the reinforcing part 101.

[0037] The first forming module 1 and the second forming module 2 are both located before the third forming module 3. The third forming module 3 is used to punch and bend the left side plate 103 and the right side plate 104 that are in contact with both sides of the reinforcing part 101 when the upper mold assembly and the lower mold assembly are closed. At least two mounting holes 102 are formed on the left side plate 103 and the right side plate 104 respectively.

[0038] The difference between the leveling component preparation mold of this utility model and the prior art is that the order of each forming module in the leveling component preparation mold is adjusted so that the stamping and bending process of the left side plate 103 and the right side plate 104 is set after the stamping and forming process of the reinforcing part 101 and the mounting hole 102. As a result, the structure of the left side plate 103 and the right side plate 104 after forming is not affected by the structure of the reinforcing part 101. The leveling component can be directly stamped and formed on the leveling component preparation mold. That is, the lower end surfaces of the left side plate 103 and the right side plate 104 after stamping and forming are flush or nearly flush, and the positions of the mounting holes 102 on the left side plate 103 and the right side plate 104 can also correspond. After the leveling component is taken out of the mold, there is no need to add other processing steps to the leveling component, which reduces the difficulty of preparing the leveling component and improves the production efficiency of the leveling component.

[0039] In some embodiments, the third forming module 3 includes a support portion 31 formed on the lower die assembly and two stamping portions 32 formed on the upper die assembly; when the die is closed, the two stamping portions 32 are located on both sides of the support portion 31. When the die is closed, the support portion 31 abuts against the middle of the strip 100, and the support portion 31 can support at least the front and rear ends of the strip 100 at the bend. Thus, when the two stamping portions 32 move down to both sides of the support portion 31, the left side plate 103 and the right side plate 104 can be smoothly stamped and bent on both sides of the strip 100.

[0040] In some embodiments, the lower mold assembly forms clearance portions 6 on both sides of the support portion 31. The clearance portion 6 extends through the lower mold assembly on the side away from the first forming module 1, so that the left side plate 103 and the right side plate 104 can be smoothly moved out of the mold after being formed on the strip 100.

[0041] In some embodiments, the leveling part preparation mold further includes a fourth forming module 4, which is located after the first forming module 1 and the second forming module 2, and before the third forming module 3. The third forming module 3 is used to stamp out material distribution portions 106 on both sides of the strip 100 when the upper mold assembly and the lower mold assembly are closed. The material distribution portions 106 are notches formed on the strip 100. Thus, when the left side plate 103 and the right side plate 104 are subsequently stamped and bent, it is not necessary to cut the left side plate 103 and the right side plate 104 off the front end of the strip 100, which reduces the difficulty of stamping and bending, improves the yield of the leveling part, and also prevents the left side plate 103 and the right side plate 104 from undergoing tensile deformation in the front-back direction during the bending process, making the position of the mounting holes 102 more controllable and ensuring that the positions of the mounting holes 102 on the left side plate 103 and the right side plate 104 correspond after bending.

[0042] In some embodiments, the width of the front and rear sides of the material distribution section 106 corresponding to the position of the left side plate 103 is not less than the width of the left side plate 103, thereby ensuring that no cutting process occurs between the left side plate 103 and the material strip 100 during the bending and forming process.

[0043] In some embodiments, the width of the front and rear sides of the material distribution section 106 corresponding to the position of the right side plate 104 is not less than the width of the right side plate 104, thereby ensuring that the right side plate 104 does not undergo any cutting process with the strip 100 during the bending and forming process.

[0044] In some embodiments, the mounting hole 102 includes a first hole portion 1021 and a second hole portion 1022 that are connected to each other. The second forming module 2 includes a first punch 21 for forming the first hole portion 1021 on the strip 100 and a second punch 22 for forming the second hole portion 1022 on the strip 100. By forming the mounting hole 102 in two parts using the first punch 21 and the second punch 22, the quality of the formed mounting hole 102 can be improved, so that the rod can be better riveted into the mounting hole 102. It should be noted that the first punch 21 and the second punch 22 are both provided on the upper die assembly, while the lower die assembly has corresponding matching first and second recesses.

[0045] In some embodiments, the leveling part preparation mold further includes a positioning module 5. The positioning module 5 includes a third punch 51 for stamping a positioning hole 105 on the strip 100 when the upper mold assembly and the lower mold assembly are closed, and a positioning punch 52 for being placed in the positioning hole 105 when the upper mold assembly and the lower mold assembly are closed. During the travel of the strip 100, the positioning of the strip 100 is achieved by the cooperation of the positioning punch 52 with the positioning hole 105, thereby ensuring that each forming module can be stamped at a specific position on the strip 100. It should be noted that the third punch 51 and the positioning punch 52 are both provided on the upper mold assembly, while the lower mold assembly has corresponding matching third and fourth recesses.

[0046] A method for preparing a leveling component includes the following steps:

[0047] S1. A recessed reinforcing portion 101 and at least two mounting holes 102 are stamped and formed on the strip 100. The at least two mounting holes 102 are distributed on both sides of the reinforcing portion 101. The forming order of the reinforcing portion 101 and the mounting holes 102 is not limited.

[0048] S2. The material distribution section 106 is formed by stamping on both sides of the strip 100;

[0049] S3. A left side plate 103 and a right side plate 104 are punched and bent on the strip 100, and at least two mounting holes 102 are formed on the left side plate 103 and the right side plate 104 respectively.

[0050] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
