Description

Technical Field

[0001] The utility model relates to the field of bending moulds, in particular to a movable bending mould for a podium enclosure. Background Art

[0002] During the processing of the podium enclosure, the upper and lower ends of the enclosure need to be bent so that the edges are in a "U" shape, so that there are no sharp transition corners on the edge of the podium, avoiding scratches in later use and effectively reducing safety hazards in use.

[0003] However, the existing "U"-shaped corners generally adopt a direct bending structure, and then the product is directly pulled out from the side of the mold. For products with shorter lengths, the pulling out is relatively simple. For the podium enclosure, its length is longer. Therefore, during the pulling out process, it is easy to cause stress deformation of the enclosure and scratches on the product, which seriously affects the processing efficiency and quality. Summary of the invention

[0004] The main purpose of the utility model is to provide a movable bending mold for a podium enclosure, aiming to improve the structure of the mold, facilitate the demoulding of the enclosure, reduce the stress problem of the product after processing, and effectively improve the processing quality.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a movable bending mold for a podium enclosure, comprising a bottom mold and a bending mold.

[0006] The bottom mold comprises a base, a fixed mold installed on the base, and a swing seat swingably installed on the base, wherein the fixed mold and the swing seat are respectively provided with a first molding groove and a second molding groove.

[0007] The bending die is cylindrical;

[0008] When the bending die and the bottom die are closed, the bending die fits the enclosure plate and drives the first forming groove and the second forming groove to approach each other, so that the first forming die and the second forming die are surrounded into a "U" shape.

[0009] The technical solution of the utility model forces the first molding die and the second molding die to be close to each other through the fitting pressure of the bending die, thereby realizing the mold closing of the enclosure plate. When demolding is required, when the bending die moves up, the swing seat swings to a position away from the product, thereby avoiding the problem of product jamming. The demolding is fast, and the linear demolding effectively reduces the bending stress, that is, the swing seat can absorb part of the excess fitting pressure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0015] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0016] like Figure 1 to Figure 2 As shown, a movable bending mold for a podium enclosure comprises a bottom mold 1 and a bending mold 2.

[0017] The bottom mold 1 includes a base 10, a fixed mold 11 installed on the base 10, and a swing seat 12 swingably installed on the base 10. The fixed mold 11 and the swing seat 12 are respectively provided with a first molding groove 31 and a second molding groove 32.

[0018] The bending die 2 is cylindrical;

[0019] When the bending die 2 and the bottom die 1 are closed, the bending die 2 fits the enclosure plate and drives the first forming groove 31 and the second forming groove 32 to approach each other, so that the first forming die and the second forming die are surrounded into a "U" shape.

[0020] Through the fitting pressure of the bending die 2, the first molding die and the second molding die are forced to be close to each other, thereby realizing the mold closing of the enclosure. When demolding is required, when the bending die 2 moves up, the swing seat 12 swings to a position away from the product, thereby avoiding the problem of product jamming. The demolding is fast, and the linear demolding effectively reduces the bending stress (that is, the swing seat 12 can absorb part of the excess fitting pressure).

[0021] Specifically, the base 10 and the fixed mold 11 are integrally formed, which can make the mold more durable.

[0022] More specifically, the base 10 is provided with a notch 4 , an end of the notch 4 is provided with a swing shaft (not shown), and the fixed mold 11 is pivotally mounted on the notch 4 via the swing shaft, thereby achieving relative movement between the fixed mold 11 and the swing seat 12 .

[0023] In the embodiment of the utility model, the notch 4 is in the shape of an inclined surface, so that the swing axis can swing as a supporting surface.

[0024] Furthermore, an elastic member 5 is provided between the inner wall surface of the notch 4 and the rear wall of the swing seat 12 , and the elastic member 5 can apply an elastic force to the swing seat 12 away from the fixed mold 11 .

[0025] Furthermore, the elastic member 5 is a tension spring or a spring bolt, which can realize the rapid reset of the pendulum seat 12 and is easier to install.

[0026] In an embodiment of the utility model, the notch 4 is provided with a right-angle groove 61, and the swing shaft is provided with a right-angle portion 61 matching the right-angle groove 61, and the right-angle portion swings with the right-angle groove 61 as a fulcrum. In another embodiment, the swing shaft uses a spring bolt as a pull rod (the base of which is provided with a swing hole larger than other bolts), thereby realizing the swinging and resetting of the swing shaft.

[0027] Specifically, the bending die 2 is connected to the bending device through a clamping portion, and the bending device is provided with a clamping groove. An avoidance position (i.e., a gap) is provided between the clamping groove 71 and the clamping portion 72. The setting of the avoidance position can prevent the bending die 2 from being stuck, thereby facilitating demoulding.

[0028] More specifically, at least two spring bolts are provided.

[0029] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
