Description

Technical Field

[0001] The utility model belongs to the technical field of box manufacturing, and particularly relates to a flow channel changing box. Background Art

[0002] The main function of the box is to protect the internal environment and structure from the external environment. It is one of the important components of the vehicle. Casting is a method of pouring liquid metal into the mold cavity and obtaining a blank or part of a certain shape after it cools and solidifies. Most boxes are cast.

[0003] Since the box body is integrally formed and has a relatively complex structure, the corresponding box body molding mold is also complex in structure. During casting, air is easily trapped in the casting cavity of the mold, resulting in bubble holes on the molded box body and a low production qualification rate. Utility Model Content

[0004] The purpose of the utility model is to provide a flow channel changing box body in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a flow channel changing box, comprising a box body, wherein an input flange and an output flange are respectively arranged on the left and right sides of the box body, wherein the input flange and the output flange have the same structure and are arranged symmetrically with respect to the center, and taking the input flange as an example, a first sealing groove is opened on the input flange around the box port, and second sealing grooves are respectively opened at two diagonal positions on a certain diagonal line, and a plurality of flange connection holes are opened at the four corners of the input flange around the first sealing groove and the second sealing groove;

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 to Figure 2 As shown, the modified flow channel box includes a box body 100, and the left and right sides of the box body 100 are respectively provided with an input flange 110 and an output flange 120, the front side is provided with a mounting flange 130, and the back side is provided with a flow channel flange 140. The input flange 110, the output flange 120, the mounting flange 130 and the flow channel flange 140 are all integrally formed with the box body 100.

[0017] A positioning hole 150 is formed at the center of the top of the box body 100 to facilitate installation and positioning during box processing and use; a plurality of base bolt heads 160 are formed at the bottom of the box body 100, and the base bolt heads 160 are fixed to the bottom structure by bolt connections. The number of base bolt heads 160 should be 4 or more to ensure the stability of the box after it is fixed and prevent displacement.

[0018] like Figure 1As shown, the input flange 110 and the output flange 120 have the same structure and are centrally symmetrically arranged with each other, and a box port is opened at the center of the input flange 110 and the output flange 120. A box port is also opened at the center of the mounting flange 130, and mounting bolt heads 131 are formed at the four corners of the mounting flange 130 around the box port, respectively, and the mounting bolt heads 131 facilitate the mounting flange 130 to be fixedly connected to the corresponding structure by bolt connection.

[0019] Taking the input flange 110 as an example, a first annular sealing groove 111 is opened on the input flange 110 in the circumferential direction outwardly around the port of the box body, and annular second sealing grooves 112 are opened on a certain diagonal line of the input flange 110 and at two opposite corners of the input flange 110 respectively. The second sealing groove 112 has a smaller diameter. The first sealing groove 111 and the second sealing groove 112 are continuously arranged on the input flange 110 as a whole, and sealing rings are installed in the grooves to ensure the sealing of the connection between the input flange 110 and the input end structure.

[0020] The two opposite corners on the other diagonal line of the input flange 110 are cut, and a plurality of flange connection holes 113 are respectively opened at the four corners of the input flange 110 around the first sealing groove 111 and the second sealing groove 112, and the number of flange connection holes 113 on each corner is 2 to ensure the tightness of the connection between the input flange 110 and the input end structure. The structure on the output flange 120 is the same as that on the input flange 110.

[0021] like Figure 2 As shown, the flow channel flange 140 is provided with a central flow channel 143 in the center, and a flow channel cover 144 is integrally formed in the central flow channel 143; an annular third sealing groove 141 is provided circumferentially on the flow channel flange 140 outward from the central flow channel 143, and a sealing ring is provided in the third sealing groove 141 to ensure the sealing of the connection between the flow channel flange 140 and the pipeline. Flange fixing holes 142 are respectively provided at the four corners of the flow channel flange 140 around the third sealing groove 141, and the flange fixing holes 142 facilitate the connection of the flow channel flange 140 with the pipeline.

[0022] The structural principle of the utility model is as follows: the central flow channel 143 of the traditional box flow channel flange 140 is an open hole design, and the six sides of the box have relatively complex molding structures. Therefore, the corresponding structure of the box molding mold is also relatively complex, and the problem of air entrapment in the mold cavity is prone to occur during casting, resulting in a low qualified rate of box casting products.

[0023] The utility model adds an integrally formed flow channel cover 144 in the central flow channel 143 to close the central flow channel 143 during the casting process, which can simplify the box molding mold with minimal changes in the box structure, reduce the difficulty of box casting, and effectively avoid the problem of trapped air in the box molding. After the box casting is completed and cooled and demolded, the box flow channel flange 140 is processed and the flow channel cover 144 is cut and removed. The process is simple and ensures that the finished box structure is consistent with that of the traditional box casting. It greatly improves the qualified rate of box product production, improves box production efficiency, and reduces production costs.

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
