DETAILED DESCRIPTION

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0023] The present application discloses a method for assembling and welding mold parts. By using welding tools to limit and fix the pipe fittings and the base of the mold during welding, the welding deformation can be reduced, thus solving the problems of welding deformation and poor size control in the prior art.

[0024] The mold welding tool is used to fix the mold pipe 5 and base 4 during mold welding. The welding position of the base 4 is provided with a positioning boss 41. During welding, the pipe 5 is sleeved on the positioning boss 41, and the pipe 5 and the positioning boss 41 are clearance-fitted or transition-fitted.

[0025] like Figure 1 and 2 The mold welding tool shown includes: a support member 1, a first connecting component 2 and a second connecting component 3.

[0026] One end of the support member 1 is provided with a hole 13, and the other end is provided with a groove 12. The first connecting component 2 is connected to the end of the support member 1 provided with the hole 13, and the second connecting component 3 is connected to the end of the support member 1 provided with the groove 12. Figure 1 and 2 The groove portion 12 shown is a U-shaped groove that penetrates two opposite side walls of the support member 1.

[0027] The hole 13 of the support member 1 is used for sleeve-mounting the pipe 5 of the mold, and the hole 13 of the support member 1 and the pipe 5 are clearance-matched.

[0028] The first connecting component 2 cooperates with the pipe fitting 5 of the mold at one end of the hole 13, and the second connecting component 3 cooperates with the base 4 of the mold. The first connecting component 2 and the second connecting component 3 are used to fix the pipe fitting 5 and the base 4 of the mold.

[0029] The position of the groove 12 of the support member 1 matches the position of the welding part of the pipe 5 and the base 4 of the mold. When welding, the welding equipment is extended into the groove 12 to weld the welding part of the pipe 5 and the base 4 of the mold. Figure 2 The outer and inner edges of the support member 1 shown are provided with weight-reducing chamfers.

[0030] The inner diameter of the hole portion 13 of the support member 1 is clearance-matched with the outer diameter of the tube 5 of the mold, and the outer diameter of the positioning boss 41 of the base 4 is clearance-matched or transition-matched with the inner diameter of the tube 5, so as to radially limit one end of the tube 5. The second connecting component 3 realizes radial and axial limitation of the base 4, and the axial limitation of the tube 5 and the base 4 is realized by the first connecting component 2 and the second connecting component 3.

[0031] The first connecting component 2 and the second connecting component 3 fix the pipe fitting 5 and the base 4 of the mold, and after applying a predetermined pressure toward the welding parts of the pipe fitting 5 and the base 4 of the mold, the groove 12 corresponds to the welding parts of the pipe fitting 5 and the base 4 of the mold, and the groove 12 of the support member 1 connects the welding parts of the pipe fitting 5 and the base 4 of the mold with the outside world, so that the welding parts of the pipe fitting 5 and the base 4 of the mold are exposed to the outside world, which can facilitate external welding equipment to weld the welding parts of the pipe fitting 5 and the base 4 of the mold.

[0032] In this embodiment, the side wall of the support member 1 is provided with a lifting screw hole 11, which is used to connect an external lifting device.

[0033] like Figure 1 As shown, a lifting screw hole 11 is respectively provided on the two side walls on the opposite sides of the support member 1 .

[0034] By connecting an external lifting tool through the lifting screw hole 11, the welding tool and the pipe fittings 5 ​​and the base 4 of the mold can be lifted and moved, which is convenient for moving the welding tool and the pipe fittings 5 ​​and the base 4 of the mold between the assembly station, the heating station and the welding station.

[0035] In this embodiment, the first connecting assembly 2 includes: a pressing block 21 , a gasket 23 and a first screw 22 .

[0036] The clamping block 21 is connected to the support member 1, the first screw 22 is screwed to the clamping block 21, the gasket 23 is connected to the first screw 22, and the shape of the gasket 23 matches the shape of one end of the pipe 5 provided in the hole 13, as shown in FIG. Figure 1 The clamping block 21 is arranged in the end of the pipe 5 , which can apply an axial force to the pipe 5 toward the base 4 and can also limit the end of the pipe 5 in the radial direction.

[0037] When in use, the gasket 23 abuts against one end of the pipe 5 disposed in the hole 13 , and the first screw 22 applies a force to the pipe 5 through the gasket 23 .

[0038] The gasket 23 is made of a metal material with a hardness lower than that of the pipe 5 .

[0039] The pressing block 21 can be an integrated structure with the support member 1, or it can be Figure 1 and 2 The pressing block 21 is mounted on the supporting member 1 by screws.

[0040] The first screw 22 is used to apply a force to the pipe 5 toward the welding position between the pipe 5 and the base 4 .

[0041] The gasket 23 is matched with the shape of the end of the pipe fitting 5 to make the end of the pipe fitting 5 evenly stressed, and then the position of the first screw 22 on the clamping block 21 is adjusted by the threaded connection between the first screw 22 and the clamping block 21, so that the force of the first screw 22 is transmitted to the pipe fitting 5 through the gasket 23, and the magnitude of the force on the pipe fitting 5 can also be adjusted by rotating the first screw 22, so that the welding deformation can be reduced by fixing the pipe fitting 5 and the base 4 of the mold during welding.

[0042] In this embodiment, the gasket 23 is made of copper.

[0043] The gasket 23 made of a relatively soft copper material abuts against the pipe fitting 5 of the mold, thereby preventing the pipe fitting 5 of the mold from being damaged.

[0044] In this embodiment, the second connecting assembly 3 is a plurality of second screws, and the second screws pass through the supporting member 1 and are screwed to the base 4 of the mold.

[0045] like Figure 2 As shown, the second screw, the base 4 of the mold and the support member 1 are connected, and the base 4 of the mold and the support member 1 are abutted against each other. A avoidance groove that cooperates with the base 4 of the mold is also provided at the end of the support member 1, so that the base 4 of the mold and the support member 1 can be stably connected.

[0046] In this embodiment, a relief cavity 14 is provided at a position of the groove 12 close to the welding portion between the pipe 5 and the base 4 of the mold, and the distance between the two side walls of the relief cavity 14 is greater than the distance between the two side walls of the "U"-shaped groove.

[0047] The distances between the two side walls of the avoidance cavity 14 and the side walls of the welding position of the pipe 5 and the base 4 of the mold are equal.

[0048] The avoidance cavity 14 is used to avoid the welding part of the pipe fitting 5 and the base 4 of the mold, thereby increasing the distance between the side wall of the groove 12 and the welding part of the pipe fitting 5 and the base 4 of the mold, which can further facilitate external welding equipment to weld the welding part of the pipe fitting 5 and the base 4 of the mold.

[0049] Working principle: Before welding, first, one end of the pipe fitting 5 is sleeved on the positioning boss 41 of the base 4, and then the hole 13 of the support 1 is sleeved on the other end of the pipe fitting 5, and the second connecting component 3 is used to fix the base 4 and the support 1, and then the first connecting component 2 is used to fix the other end of the pipe fitting 5 and apply an axial force toward the base 4, and then the external lifting tool is connected through the lifting screw hole 11 of the support 1, and the welding tool and mold are moved to the welding station using the external lifting tool.

[0050] During welding, since the groove 12 and the avoidance cavity 14 of the support member 1 expose the welding parts of the pipe fitting 5 and the base 4 of the mold to the outside, the welding parts of the pipe fitting 5 and the base 4 of the mold can be welded by extending the external welding equipment into the groove 12 and the avoidance cavity 14 of the support member 1. During the welding process, the positioning boss 41 of the base 4 radially limits one end of the pipe fitting 5, the first connecting component 2 fixes the other end of the pipe fitting 5 and applies an axial force toward the base 4, and the second connecting component 3 fixes the base 4 and the support member 1, thereby greatly reducing the welding deformation.

[0051] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
