Abstract
Description
Technical Field
[0001] The present application relates to the technical field of spare part production, and specifically discloses a production mold for the right lower bracket of a manifold pipe. Background Art
[0002] A manifold pipe is a pipe applied between two storage chambers and used to connect the two storage chambers. During the installation process of the manifold pipe, a bracket is required to support and protect the end or the whole of the manifold pipe. Specifically, a combined bracket is usually used for the installation and fixation of the manifold pipe. The combined bracket can be divided into a left bracket and a right bracket, and each side bracket can be further divided into an upper bracket and a lower bracket.
[0003] In the prior art, for the production of the right lower bracket, it is usually pressed from a plate by a single-process mold, specifically, by a V-shaped single-process mold. During the pressing process of the V-shaped single-process mold, since the internal pressing chamber is V-shaped and the distance between adjacent chambers is too small, the size of the right lower bracket pressed out is unstable and the rejection rate is high.
[0004] Therefore, in view of this, the inventor provides a production mold for the right lower bracket of a manifold pipe to solve the above problems. Summary of the Utility Model
[0005] The purpose of the present utility model is to solve the problem that the traditional production of the right lower bracket of a manifold pipe is formed by pressing with a V-shaped single-process mold, and the size of the right lower bracket pressed out is unstable due to the too small distance between adjacent chambers during the pressing process.
[0006] To achieve the above purpose, the basic scheme of the present utility model provides a production mold for the right lower bracket of a manifold pipe, including:
[0007] An upper sandwich layer, which includes an upper die base, an upper clamping plate detachably connected to the inner side of the upper die base, and a forming punch detachably connected to the inner side of the upper clamping plate;
[0008] A lower sandwich layer, which is arranged opposite to the upper sandwich layer. The lower sandwich layer includes a lower die base, a lower backing plate detachably connected to the inner side of the lower die base, and a lower template detachably connected to the inner side of the lower backing plate;
[0009] A moving cavity for accommodating the movement of the plate is provided between the lower template and the forming punch. An shaping cavity for the forming punch to press into and shape the plate is also provided inside the lower template. The shaping cavity is an L-shaped shaping cavity. The two ends of the L-shaped shaping cavity are horizontal, and the height of one end is higher than that of the other end. An arc transition section with an opening inward is also formed between the two ends of the L-shaped shaping cavity, and the height of the top of the arc transition section is higher than the heights of the two ends.
[0010] Further, both ends of the L-shaped shaping chamber are horizontal, and the height of one end is higher than that of the other end. An arc-shaped transition section with an inward opening is formed between the two ends of the L-shaped shaping chamber.
[0011] Further, a gap is formed between the L-shaped shaping chamber and the outer wall of the lower template.
[0012] Further, at least one set of positioning pins is provided between the forming punch and the upper clamping plate.
[0013] Further, a support structure is provided at the bottom of the lower sandwich layer.
[0014] Further, the support structure includes a lower support plate and a plurality of lower foot pads detachably connected to the inner side of the lower support plate, and the tops of the lower foot pads are detachably connected to the bottom of the lower die base.
[0015] Further, a plurality of fixing clamp blocks for fixing the plate member are circumferentially arranged on the lower template outside the L-shaped shaping chamber.
[0016] The principle and effect of this solution are as follows:
[0017] 1. Compared with the prior art, the present utility model replaces the V-shaped single-process die with an L-shaped shaping chamber. After moving the plate member into the L-shaped shaping chamber and fixing it, the forming punch cooperates with the L-shaped shaping chamber to press and form the plate member to produce the right lower bracket of the manifold.
[0018] 2. Compared with the prior art, in the L-shaped shaping chamber of the present utility model, during the forming process, since the corner angle of the L-shaped shaping chamber is greater than the corner angle of the V-shaped single-process die, it can prevent the connection at the corner during the forming process of the right lower bracket of the manifold, prevent the inconsistent dimensions at the corner of the produced right lower bracket of the manifold, and solve the problem that the traditional right lower bracket of the manifold is pressed and formed by using a V-shaped single-process die, and the dimensions of the right lower bracket are unstable due to the too small distance between adjacent chambers during the pressing process.
[0019] 3. Compared with the prior art, an arc-shaped transition section with an inward opening and a height higher than the heights of both ends is formed between the two ends of the L-shaped shaping chamber of the present utility model, and the outer wall of the manifold can be completely wrapped by the arc-shaped transition section, providing better support for the manifold.

[0025] A production mold for the right lower bracket of a manifold tube, as shown in the embodiment Figure 1 as follows:
[0026] Includes an upper sandwich layer and a lower sandwich layer. During use, the upper sandwich layer and the lower sandwich layer are respectively installed on the slider and the table surface of a press.
[0027] Specifically, the upper sandwich layer includes an upper die base 1 installed inside the slider of the press, an upper clamping plate 2 installed inside the upper die base 1, and a forming punch 3 installed inside the upper clamping plate 2.
[0028] The lower sandwich layer is disposed opposite to the upper sandwich layer. The lower sandwich layer includes a lower die base 6 installed on the table surface, a lower backing plate 5 installed inside the lower die base 6, and a lower template 4 installed inside the lower backing plate 5.
[0029] A moving cavity for accommodating the movement of the plate is formed between the lower template 4 and the forming punch 3. Moreover, a shaping cavity for the forming punch 3 to press into and shape the plate into the right lower bracket of the manifold tube during stamping is opened inside the lower template 4. In this embodiment, the shaping cavity is an L-shaped shaping cavity 11. Correspondingly, the bottom end face of the forming punch 3 also varies with the L-shaped shaping cavity 11.
[0030] As Figure 2 shown, both ends of the L-shaped shaping cavity 11 are kept horizontal, and the height of the left end is higher than that of the right end. An arc-shaped transition section with an opening inward is formed between the left end and the right end of the L-shaped shaping cavity 11, and the topmost point of the arc-shaped transition section is flush with the height of the left end. The plate formed by the arc-shaped transition section plays a role in wrapping the manifold tube. A plurality of fixed clamping blocks 9 for fixing the plate are also circumferentially installed on the lower template 4 outside the L-shaped shaping cavity 11.
[0031] A gap is also formed between the L-shaped shaping chamber 11 and the outer wall of the lower template 4.
[0032] In this embodiment, two groups of positioning pins 10 are arranged between the forming punch 3 and the upper clamping plate 2.
[0033] Moreover, a fixed support structure is installed at the bottom of the lower sandwich layer. The fixed support structure includes a lower support plate 8 and a number of lower foot pads 7 respectively installed inside the lower support plate 8. The tops of the lower foot pads 7 are all installed at the bottom of the lower die base 6.
[0034] When the utility model is in use, the plate member is placed in the L-shaped shaping chamber 11, the slider of the press is started, and the plate member fixed by the fixed clamping block 9 is pressed into the L-shaped shaping chamber 11 to prepare the lower right bracket. The lower right bracket formed by the arc portion plays a supporting role for the manifold.

Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.
