As can be seen from the side cross-sectional view of FIG. 4C, the height of the main body of the male mold 10 is hi, and the height of the first welding chamber 31 (first recess 14) is h2, which is the height of the main body of the male mold 10. In other words, theoretically, the height h2 of the first bonding chamber 31 is greater than 0 and less than hi. However, the difference between the hi and h2 is actually the thickness of the feeding window 11 and the bridge portion 11a, so H2 is not too close to the hi. As shown in Fig. 4C, the height of the first bonding chamber 31 of the present invention is 1/2 of the height of the main body of the male mold 10. In addition, the inner wall of the bonding chamber 30 (the connecting portion 12) The distance d between the wall surface and the first protruding portion 14a and the second protruding portion 22a is not too wide to affect the pressing effect, and the distance d is preferably less than 1 / 2 of the height of the main body of the male mold 10. Figure 5 is a side view showing a first embodiment of the present invention for a non-weld aluminum alloy slotted extrusion die. As shown in Fig. 5, a cylindrical alloy 7,000 series key : Material A, after the extrusion die, is output as an aluminum alloy square tube B. Please refer to FIGS. 6A to 6E, which are cross-sectional views of the cross-sectional positions of FIG. 5, thereby illustrating the ingot A in the mold. Internal shunting, splicing and forming. Please refer to Figure 6A, before the ingot A has entered the mold, 11 201136678 shows that the ingot A has a circular cross section. Referring to FIG. 6B, when the ingot A is pushed into the four feeding windows 11 by the pressure, the infusion window 11 is divided into four ingots A, and each ingot A is presented with the infusion. The section of the material window 11 has the same sector shape. Referring to FIG. 6C, when the ingot A enters the first welding chamber 31 of the welding chamber 30, the four ingots A are press-bonded into one ingot A, and the outer shape of the ingot A It is approximately circular like the wall surface of the first recess 14 of the high-mold 10 and the second recess 22 of the master 20, and the inner circumference of the ingot is square in the same shape as the connecting portion 12 of the male mold 10. Referring to FIG. 6D, when the ingot A enters the second bonding chamber 32 of the bonding chamber 30, its shape is equivalent to that of FIG. 6C. The four broken lines indicate the welding position of the welding chamber 30, which is located between the projections 14a, 22a and the connecting portion 12 of the male mold 10. In the first embodiment of the invention, the welding position is also between the corners of the projections 14a, 22a and the connecting portion 12 of the male mold 10. Referring to FIG. 6E, when the ingot A enters the guiding chamber 40, the peripheral shape of the ingot A is the same as the wall surface of the forming outer mold portion 23 of the female mold 20, and the ingot A The inner circumference shape is the same as the square shape of the molded inner mold portion 13 of the male mold 10. Therefore, after passing through the guide chamber 40, the material A has been further formed into one of the tubes B, and is outputted outward from the bottom of the mold. As described above, FIGS. 6A to 6E disclose the molding process of the present invention for the 12 201136678 non-weldable aluminum alloy slotted pipe extrusion die, and particularly described herein are: (for example, the seven thousand series) The design of the extruded tube extrusion die is different from the general aluminum alloy (for example, the six thousand series) extrusion die design direction. Compared with the conventional extrusion die, the design direction is toward increasing the extrusion speed. The increase in production capacity, but also the inability to produce a large press pressure, is therefore not suitable for the extrusion of alloy materials that are not easily soldered. However, the design direction of the extrusion die of the present invention does not focus on the speed of production, but it is desirable to produce a large pressing pressure at the welding position so that the non-weldable aluminum alloy can be pressed. The so-called press-bonding, so-called metal diffusion bonding, is to jump and join atoms between metal and metal (homogeneous metal or heterogeneous metal) between two layers of metal under high pressure and high temperature. With solder, you can accept contracted or heterogeneous metals. Referring to FIG. 4C again, the welding chamber 30 of the mold is composed of the first welding chamber 31 of the male mold 10 and the second welding chamber 32 of the female mold 20. The height of the main body of the male mold 10 For hi, the height of the first welding chamber 31 is h2. In conventional aluminum extrusion dies, generally only the welding chamber 30 is provided on the master mold 20 to meet the needs of the mold. However, in the first embodiment of the present invention, the extrusion die increases the first welding chamber 31' located in the male mold 10 so that the height of the integral welding chamber 30 is greatly increased, and the ingot A is in the extrusion mold. The internal resistance also increases, which in turn increases the overall pressure in the mold and greatly increases the pressing pressure at the welding position in the welding chamber 30, so that the aluminum alloy which is difficult to weld can be pressed. 201136678 - meeting ΐ γ refers to the 7A to 7B drawings, which discloses the first alloy of the first embodiment of the present invention, which is not easy to weld aluminum alloy, and the mold is similar to the present invention. - the embodiment, and has the same ^ = the difference is that in the second actual pass, the extrusion die can be designed into various different types of welding chambers, 5 main: "/: The first tan junction chamber 31 height h2 is: 1/4 of the body dimension; and the first weld of the 7B diagram: the material mold, the body height. Among them, the ratio of the different C σ to 31 degree h2 to the height h of the main body of the male mold 10 is different for the welding to 30 pressure. Persons ~ For example, according to the second embodiment of the present invention, the material having the first welds 2 to 31 does increase the maximum pressure 2 generated by the extrusion die, and with the height h2 of the first weld chamber 31 The addition of the ® force is also added, and in the case of h2=3/4hl, the result is that the result is that the alloy is not bonded, and the crucible can be applied to the extrusion process by increasing the pressing pressure. Another grain: taking into account the actual demand pressure of the mold, too much pressure will only cause the negative effect of the 31 Gu Mo, and the first welding chamber still h2 too high will lead to the feeding window丨丨And the thickness of the bridge portion n = foot affects the overall strength of the extrusion die. Therefore, the height h2 of the = coupling chamber 31 of the present invention is preferably the height h y 1 Λ 4 to 3/4 of the main body 10 of the male mold 10, in particular, the height h2 of the first welding chamber 31 is 1/1 of the height of the main body 2 is the best. 201136678 shows: not the first embodiment and the second embodiment of the joint 10 of the joint 12 ^ alloy with a seam extrusion die 'where the male mold material is extruded into a square == two 13 It is a square shape, and four round ingots are used, and the feeding window with the human square ~= shape is considered to be an embodiment in the welding position of the square tube: the square tube:: The invention is not limited to Here's the next two
