[0019] In the utility model, except another explicit provision and limitation, if there is term "assembling", "connecting", "connection" term, it should be understood as broad sense, for example, it can be fixed connection, can be detachable connection, or integrally connected;It can be mechanical connection;It can be directly connected, can be connected through intermediate medium, can be two elements internal intercommunication.For ordinary skilled person in the art, the specific meaning of above-mentioned term in the utility model can be understood according to specific situation.
[0020] The technical scheme of the utility model and its beneficial effects are more clear and explicit by further describing the specific embodiment of the utility model in combination with the drawings of the specification below.The embodiment is exemplary, and is intended to explain the utility model, and can not be understood as the limitation of the utility model.
[0021] The preferred embodiment provided by the utility model is as follows: Figures 1-4As shown in the drawings, an aluminum extrusion mold opener includes a base 1, a pull rod 2, an opener upper seat 3, an opener lower seat 4, a jack 5, which is a hydraulic jack; the jack 5 is provided with a pressing rod 51 to push the movable end of the jack 5 to move upward and contact the opener lower seat 4; the opener upper seat 3 and the base 1 are respectively provided with a jack 11 for the pull rod 2 to be inserted; the opener upper seat 3, the base 1 and the pull rod 2 are fixed by pin connection.
[0022] The base 1 and the opener upper seat 3 are respectively installed at both ends of the pull rod 2, and the opener lower seat 4 is sleeved on the pull rod 2 to slide along the pull rod 2; the pull rod 2 is sleeved with a limiting rod 6, which is a hollow structure to facilitate the pull rod 2 to pass through the limiting rod 6; the limiting rod 6 is arranged between the opener lower seat 4 and the base 1, and the diameter of the limiting rod 6 is greater than the diameter of the hole of the opener lower seat 4, so as to limit the movement position of the opener lower seat 4.
[0023] The opener upper seat 3 is provided with a first wedge block 31, the opener lower seat 4 is provided with a second wedge block 41, and the jack 5 is installed on the base 1 and located below the opener lower seat 4; the opener lower seat 4 is pushed by the movable end of the jack 5 to separate the mold placed between the opener upper seat 3 and the opener lower seat 4 through the clamping of the first wedge block 31 and the second wedge block 41.
[0024] The opener upper seat 3 is provided with a first recess 32, and the opener lower seat 4 is provided with a second recess 42; the opener upper seat 3 and the opener lower seat 4 are movably connected to make the first recess 32 and the second recess 42 engage to form an opening position 12, and the mold to be opened is placed in the opening position 12. The first wedge block 31 is arranged in the first recess 32, the second wedge block 41 is arranged in the second recess 42, and the first wedge block 31 and the second wedge block 41 are oppositely arranged.
[0025] As shown in the drawings, Figure 4 The aluminum extrusion mold 7 is composed of a front mold 71 and a rear mold 72; during production, the aluminum rod material is extruded into the three holes of the front mold 71 by the extruder, and then flows out of the rear mold 72; the cross section of the extruded profile is formed by the combination of the front and rear molds. After production is completed, the aluminum material that has not been extruded will fill the empty mold of the front and rear molds and cannot be separated. After production, the front and rear molds need to be separated in order to produce next time. The current production can only manually separate the front and rear molds with a hammer and a wedge, which is very low in efficiency and unsafe.
[0026] Therefore, the aluminum extrusion die opener provided by the structural scheme is specially used to separate the front die and the rear die of the extrusion die, and can realize the effect of quickly and efficiently separating the front die and the rear die. The operation process of the structure is as follows: the extrusion die is placed in the die opening position 12, the die separating position 73 of the front die and the rear die is clamped into the first wedge block 31 of the first recess position 32. The first wedge block 31 and the second wedge block 41 are located on the same horizontal plane, the movable end of the jack 5 is in contact with the die opener lower seat 4 by reciprocating downward driving, and the die opener lower seat 4 is pushed to rise, so that the second wedge block 41 is clamped into the die separating position 73. With the gradual force of the jack 5, the first wedge block 31 and the second wedge block 41 gradually enter the die separating position, so as to separate the front die 71 and the rear die 72.
[0027] The structure changes the artificial knocking into hydraulic pressure, the force is greatly improved and stable, the front die and the rear die can be quickly separated, and it takes two or three hours to separate several sets of dies manually, and now it can be completed in ten or twelve minutes. At the same time, the structure reduces the damage to the surface of the die caused by knocking, and the die is pushed out by oil pressure, so that the damage to the die is small, thereby greatly prolonging the service life of the die.
