Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a combined metal pipe end one-time molding die. Background Technology

[0002] The ends of metal tubes typically need to be extruded using a mold to form protrusions, which serve as a limiting element when connecting rubber hoses later. The core principle of forming metal tube segments using molds is to use external force to cause plastic deformation of the metal material within the mold cavity, ultimately forming a tube segment of a specific shape.

[0003] When existing molds for forming the ends of metal pipes adopt a combined structure, the sliding restriction effect on the forming slider is not good, resulting in poor forming quality of the metal pipe ends. Utility Model Content

[0004] The purpose of this invention is to provide a combined metal pipe end forming mold to solve the problem of poor sliding restriction effect of existing metal pipe end forming molds on the forming slider.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a combined metal pipe end one-time forming mold, comprising:

[0006] The mold body includes two mold units arranged symmetrically facing each other. Each mold unit includes a mold body, a slider, a pressure plate, and a baffle. The mold body is provided with a cavity, and the end of the cavity is provided with a forming groove. A metal tube is placed in the cavity. The slider is slidably connected to the mold body and elastically connected to the end face of the mold body. The slider is provided with a clamping groove corresponding to the cavity. Symmetrically arranged protrusions are provided on both sides of the slider. The pressure plate is fixedly installed on the main mold body. The side wall of the pressure plate is provided with a guide groove corresponding to the protrusion. The baffle is fixedly installed on the mold body.

[0007] The punch has a positioning groove, and a positioning rod is provided on the bottom surface of the positioning groove.

[0008] As a further description of the above technical solution:

[0009] A spring is provided on the back of the slider. One end of the spring is inserted into the mold body, and the other end is inserted into the slider.

[0010] As a further description of the above technical solution:

[0011] Two springs are provided on the back of the slider, and the two springs are symmetrically arranged on both sides of the clamping groove.

[0012] As a further description of the above technical solution:

[0013] Symmetrically arranged protrusions are provided on both sides of the baffle. The protrusions abut against the side of the pressure plate. The baffle is fixedly installed on the pressure plate by bolts. The bolts pass through the protrusions and are threaded onto the pressure plate.

[0014] As a further description of the above technical solution:

[0015] A chamfered end is provided at one inner corner of the pressure plate, and a stepped surface corresponding to the chamfered end is provided on the mold body.

[0016] As a further description of the above technical solution:

[0017] The positioning rod is threaded onto the bottom surface of the positioning groove.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, during the metal tube forming process, the slider is pressed down by the slider to control the slider to slide smoothly. At the same time, the stroke of the slider is limited by the baffle to fully restrict the movement of the slider, thus solving the problem that the existing mold for forming the end of metal tube has poor sliding restriction effect on the forming slider.

[0020] 2. In this utility model, the baffle is not only fixed to the mold body, but also to the pressure plate, which improves the integrity of the combined molding mold, prevents loosening of the installation, and ensures the limiting effect on the slider. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-4 This utility model provides a technical solution: a combined metal pipe end one-time forming mold, comprising:

[0031] The mold body includes two mold units 1 arranged symmetrically facing each other. Each mold unit 1 includes a mold body 11, a slider 12, a pressure plate 13, and a baffle 14. The mold body 11 is provided with a cavity 111 and a forming groove 112 at the end of the cavity 111. A metal tube 9 is placed in the cavity 111. The slider 12 is slidably connected to the mold body 11 and elastically connected to the end face of the mold body 11. The slider 12 is provided with a clamping groove 121 corresponding to the cavity 111. The slider 12 is provided with symmetrically arranged protruding plates 122 on both sides. The pressure plate 13 is fixedly installed on the mold body 11. The side wall of the pressure plate 13 is provided with a guide groove 131 corresponding to the protruding plate 122. The baffle 14 is fixedly installed on the mold body 11.

[0032] Punch 2 has a positioning groove, and a positioning rod 21 is provided on the bottom surface of the positioning groove.

[0033] During the metal tube 9 forming process, the slider 12 is pressed down by the slider 12 to control the slider 12 to slide smoothly. At the same time, the stroke of the slider 12 is limited by the baffle 14, which fully restricts the movement of the slider 12 and solves the problem that the existing mold for forming the end of the metal tube has poor sliding restriction effect on the forming slider.

[0034] The positioning rod 21 is threaded onto the bottom surface of the positioning groove, making it easy to disassemble and replace the positioning rod 21 to accommodate metal pipes 9 with different wall thicknesses.

[0035] Working principle: During the metal tube end forming process, the metal tube 9 is placed in the cavity 111 of the mold body 11. Then, the two mold units 1 close the mold and position the metal tube 9. Then, the punch 2 is driven by the press to squeeze the end of the metal tube 9. The end of the metal tube 9 extends into the positioning groove, and the positioning rod 21 is inserted into the metal tube 9.

[0036] As the punch 2 presses against the slider 12, the slider 12 moves backward. The slider 12 holds and drives the front end of the metal tube 9 to move backward and compress the spring. The rear part of the metal tube 9 cannot move due to the holding effect of the mold body 11. The middle part of the metal tube 9 is compressed and deformed to fill the forming groove 112 at the end of the cavity 111, thus forming the tube end. After processing, the punch 2 retracts and the slider 12 returns to its original position.

[0037] Example 2

[0038] Based on the above embodiments, this embodiment further improves upon the following technical solution: a spring 123 is provided on the back of the slider 12, one end of the spring 123 is inserted into the mold body 11, and the other end is inserted into the slider 12.

[0039] Specifically, two springs 123 are provided on the back of the slider 12. The two springs 123 are symmetrically arranged on both sides of the clamping groove 121 to effectively ensure that the slider 12 slides smoothly when it is squeezed and reset.

[0040] Example 3

[0041] Based on the above embodiments, the following improved technical solutions are further made in this embodiment: symmetrically arranged protrusions 141 are provided on both sides of the baffle 14, the protrusions 141 abut against the side of the pressure plate 13, the baffle 14 is fixedly installed on the pressure plate 13 by bolts, and the bolts are threaded onto the pressure plate 13 after passing through the protrusions 141.

[0042] The baffle 14 is fixed not only to the mold body 11, but also to the pressure plate 13, which improves the integrity of the combined molding mold, prevents loosening of the installation, and ensures the restriction effect on the slider 12.

[0043] Example 4

[0044] Based on the above embodiments, this embodiment further improves upon the following technical solution: a chamfered end 132 is provided at one inner corner of the pressure plate 13, and a stepped surface 113 corresponding to the chamfered end 132 is provided on the mold body 11.

[0045] The mold body 11 positions the pressure plate 13 through the stepped surface 113. The chamfered end 132 of the pressure plate 13 is used to distinguish the direction, which makes it easier to confirm the position of the guide groove 131 below the pressure plate 13, and at the same time avoids collision damage between the pressure plate 13 and the mold body 11 during installation.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
