Description

Technical Field

[0001] The present application relates to the technical field of spare parts production, and specifically discloses a production mold for a right upper bracket of a collecting pipe. Background Art

[0002] The manifold is a pipe used between two storage chambers to connect the two storage chambers. During the installation of the manifold, a bracket is required to support and protect the ends or the entire manifold. Specifically, a combined bracket is usually used to install and fix the manifold. The combined bracket can be divided into a left bracket and a right bracket, and each side bracket can be divided into an upper bracket and a lower bracket.

[0003] In the prior art, the production of the upper right bracket is usually performed by pressing the plate with a single-process mold, specifically, by pressing the plate with 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, the distance between adjacent chambers is too small during the pressing process, resulting in unstable dimensions of the upper right bracket and a high scrap rate.

[0004] Therefore, in view of this, the inventor provides a production mold for the upper right bracket of the collecting pipe to solve the above-mentioned problem. Utility Model Content

[0005] The utility model aims to solve the problem that the traditional production of the right upper bracket of the collecting pipe uses a V-shaped single-process mold for pressing and forming, and the distance between adjacent chambers is too small during the pressing process, resulting in unstable size of the pressed right upper bracket.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a production mold for the right upper bracket of the manifold, including:

[0007] An upper interlayer, the upper interlayer comprising 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 interlayer is arranged opposite to the upper interlayer, and the lower interlayer comprises a lower die base, a lower pad detachably connected to the inner side of the lower die base, and a lower template detachably connected to the inner side of the lower pad;

[0009] A moving cavity for accommodating the movement of the plate is provided between the lower template and the forming punch, and a shaping cavity for the forming punch to press into and shape the plate is also provided on the inner side of the lower template. The thickness of the shaping cavity gradually deepens along the moving direction of the plate and forms an L-shaped shaping cavity. Both ends of the L-shaped shaping cavity are horizontal, and the height of one end is higher than the height of the other end. An arc-shaped transition section opening inward is formed between the two ends of the L-shaped shaping cavity, and the height of the arc-shaped transition section is not higher than the height of the two end ends.

[0010] Furthermore, a gap is formed between the L-shaped shaping chamber and the outer wall of the lower template.

[0011] Furthermore, at least one set of positioning pins is provided between the forming punch and the upper clamping plate.

[0012] Furthermore, a supporting structure is provided at the bottom of the lower interlayer.

[0013] Furthermore, 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 mold base.

[0014] Furthermore, a plurality of fixing clamps for fixing the plate are provided circumferentially on the lower template on the outer side of the L-shaped shaping chamber.

[0015] The principle and effect of this scheme are:

[0016] 1. Compared with the prior art, the utility model replaces the V-shaped single-process mold with an L-shaped shaping chamber. After the plate is moved into the L-shaped shaping chamber and fixed, the plate is pressed and formed by a forming punch in cooperation with the L-shaped shaping chamber to produce the upper right bracket of the collecting pipe.

[0017] 2. Compared with the prior art, the L-shaped shaping chamber of the utility model can prevent the existence of connection at the corner during the molding process of the upper right bracket of the collecting pipe, because the turning angle of the L-shaped shaping chamber is greater than the turning angle of the V-shaped single-process mold. This can prevent the corner sizes of the upper right bracket of the collecting pipe from being different during the molding process, and solve the problem that the traditional production of the upper right bracket of the collecting pipe uses a V-shaped single-process mold for pressing and forming, and the size of the upper right bracket is unstable due to the small distance between adjacent chambers during the pressing process.

[0018] 3. Compared with the prior art, an arc-shaped transition section with an opening inward and a height lower than the height of the end portions of the two ends is formed between the two ends of the L-shaped shaping chamber of the utility model. When the collecting pipe is clamped, the outer wall of the collecting pipe can be directly adhered to through the arc-shaped transition section, and the collecting pipe can be directly pressed when the upper right bracket is closed, so that the installation is tighter.
