Abstract
Description
Technical Field
[0001] The present application relates to the technical field of component production, and specifically discloses a production mold for the upper left 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 upper left bracket, it is usually pressed from a plate by a single-process mold. Specifically, an existing press is used to drive a V-shaped single-process mold installed on the tabletop of a fixed table to press the plate to obtain a finished product of the lower left bracket. 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 during the pressing process, the dimensions of the upper left bracket pressed out are unstable and the rejection rate is high. Therefore, in view of this, the inventor provides a production mold for the upper left bracket of a manifold pipe to solve the above problems. Summary of the Utility Model
[0004] The purpose of the present utility model is to solve the problem that the traditional production of the upper left bracket of a manifold pipe uses a V-shaped single-process mold for pressing, and due to the too small distance between adjacent chambers during the pressing process, the dimensions of the finished product of the upper left bracket obtained by pressing are unstable, affecting the product quality.
[0005] To achieve the above object, the basic solution of the present utility model provides a production mold for the upper left bracket of a manifold pipe, including an upper die base and a lower die base arranged opposite to each other. The upper die base is fixedly installed at the bottom end of the slider of a press. An upper clamping plate is provided on the bottom side of the upper die base, and a forming punch for pressing a plate is detachably installed on the bottom side of the upper clamping plate. An installation frame is provided at the bottom of the lower die base, and the installation frame is detachably connected to the tabletop of a fixed table. A lower backing plate is provided on the top of the lower die base, and a lower template opposite to the upper clamping plate is provided on the top of the lower backing plate. A moving cavity for accommodating the movement of the plate is provided on the surface of the lower template close to the forming punch. A shaping cavity for allowing the forming punch to press in and for accommodating the plate for shaping processing is also provided on the side of the lower template close to the forming punch. One side of the top of the shaping cavity is communicated with one side of the moving cavity. The shaping cavity is an L-shaped cavity, and arc transition sections are provided at both internal corner ends of the shaping cavity. The arc transition sections extend upward and outward from both ends of the shaping cavity, and the surface of the shaping cavity is horizontally arranged on both sides.
[0006] The principle and effect of this basic solution are as follows:
[0007] 1. Compared with the prior art, the utility model is provided with a moving cavity, which is convenient for providing sufficient operating space for placing the plate into the mold for workpiece production and processing. By providing a shaping cavity and using a forming punch to press and shape the plate into a structure with the same outer shape as the shaping cavity, it is convenient to form the plate into the required outer shape structure.
[0008] 2. Compared with the prior art, the utility model sets the shaping cavity as an L-shaped cavity. Since the corner angle of the L-shaped cavity is greater than the corner angle of the V-shaped single-process mold, it can prevent the connection at the corner during the forming process of the upper left bracket of the manifold, thereby avoiding inconsistent dimensions at the corner of the finished product of the upper left bracket of the manifold. It solves the problem that the traditional production of the upper left bracket of the manifold uses a V-shaped single-process mold for pressing and forming, and due to the too small distance between adjacent cavities during the pressing process, the size of the finished upper left bracket obtained by pressing is unstable, affecting the product quality.
[0009] 3. Compared with the prior art, the utility model is formed with an arc transition section with an opening inward and a height lower than the heights of both ends between the two ends of the shaping cavity. When clamping the manifold, the arc transition section can directly fit the outer wall of the manifold, and can directly press the manifold tightly when closing the upper left bracket, making the installation more firm.
[0010] Furthermore, the mounting frame includes a lower support plate detachably connected to the tabletop of the fixed table and a plurality of lower foot pad columns evenly arranged between the bottom of the lower die base and the lower support plate. The lower support plate is located directly below the lower die base. By providing the lower support plate and the lower foot pad columns, it is convenient to provide structural support for the lower die base, and at the same time, it is convenient for the installation and fixation of the lower die base on the fixed table.
[0011] Furthermore, a plurality of positioning pins are symmetrically installed and connected between the forming punch and the upper clamping plate. By providing the positioning pins to connect and fix the forming punch and the upper clamping plate, the structure is simple, the disassembly and assembly are convenient, and the connection between the structures is more compact.
[0012] Furthermore, a plurality of fixing clamp blocks for fixing the plate are circumferentially and detachably installed on the lower template outside the shaping cavity. By providing the fixing clamp blocks, it is convenient to clamp and fix the plate, and avoid the plate moving in the shaping cavity and the moving cavity during the pressing and shaping process, which affects the size of the shaped finished product of the upper left bracket of the manifold.
[0013] Furthermore, the fixing clamp blocks and the lower template are detachably connected by fasteners. By installing the fixing clamp blocks on the lower module with fasteners, the disassembly is convenient, and at the same time, it is convenient for the fixing clamp blocks to limit and fix the plate.
[0014] Furthermore, a gap is formed between the shaping cavity and the side wall of the lower template. By forming a gap between the shaping cavity and the lower template, it is not only convenient for the installation of the fixing clamp blocks, but also can provide sufficient operating space for the installation and processing of the plate.

[0020] A production mold for the left upper bracket of a manifold, as shown in the embodiments Figure 1 is as follows: It includes an upper die base 1 and a lower die base 2 arranged opposite to each other. The upper die base 1 is fixedly installed at the bottom end of the slider of a press. A upper clamping plate 3 is provided on the bottom side of the upper die base 1. A forming punch 4 for pressing a plate is detachably installed on the bottom side of the upper clamping plate 3. An mounting bracket 5 is provided at the bottom of the lower die base 2. The mounting bracket 5 is detachably connected to the tabletop of a fixed table. A lower backing plate 6 is provided on the top of the lower die base 2. A lower template 7 opposite to the upper clamping plate 3 is provided on the top of the lower backing plate 6. As shown in Figure 2 it is shown that a moving cavity 8 for accommodating the movement of the plate is provided on the surface of the lower template 7 close to the forming punch 4. A shaping cavity 9 that can accommodate the pressing of the forming punch 4 and is used for shaping and processing the plate is also provided on the side of the lower template 7 close to the forming punch 4. The front side of the top of the shaping cavity 9 communicates with the rear side of the moving cavity 8. As shown in Figure 1 it is shown that the shaping cavity 9 is an L-shaped cavity. Arc transition sections 10 are provided at the internal corner ends of the shaping cavity 9. The arc transition sections 10 extend upward and outward from the left and right ends of the shaping cavity 9. The surface of the shaping cavity 9 is horizontally arranged on the front and rear sides.
[0021] Among them, as shown in Figure 1As shown, the mounting bracket 5 includes a lower support plate 11 detachably connected to the tabletop of the fixed table and four lower foot pads 12 evenly arranged between the bottom of the lower die base 2 and the lower support plate 11. The lower support plate 11 is located directly below the lower die base 2. Among them, two positioning pins 13 are symmetrically installed and connected between the forming punch 4 and the upper clamping plate 3. As Figure 1 and Figure 2 shown, among them, four fixing clamps 14 for fixing the plate member are circumferentially and detachably installed on the lower template 7 outside the shaping cavity 9. Among them, the fixing clamps 14 and the lower template 7 are detachably connected by fasteners. Among them, as Figure 1 shown, a gap is formed between the shaping cavity 9 and the side wall of the lower template 7.
[0022] In the specific implementation process of the present invention, the plate member is placed into the moving cavity 8 and horizontally moved into the shaping cavity 9 communicating with the moving cavity 8, and the plate member is clamped and fixed by the fixing clamps 14.

The upper left bracket formed by the arc transition section 10 plays a supporting role for the manifold.
[0023] Compared with the prior art, in the present invention, by setting the shaping cavity 9 as an L-shaped cavity, since the corner angle of the L-shaped cavity 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 upper left bracket of the manifold, thus avoiding the inconsistent dimensions of the finished product of the upper left bracket of the manifold at the corner, and solving the problem that the traditional production of the upper left bracket of the manifold uses a V-shaped single-process die for pressing and forming, and during the pressing process, due to the too small distance between adjacent cavities, the size of the finished product of the upper left bracket obtained by pressing is unstable, affecting the product quality;
[0024] Compared with the prior art, in the present invention, an arc transition section 10 with an opening inward and a height lower than the heights of both ends is formed between the two ends of the shaping cavity 9. When clamping the manifold, the arc transition section 10 can directly fit the outer wall of the manifold, and can directly press the manifold tightly when closing the upper left bracket, making the installation more firm.
[0025] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the above-disclosed technical content.
