Embodiment 1

[0043] The positioning tool for the coil 5 is mainly composed of a limiting component for limiting the position of the coil and a fixing component for fixing the end of the coil. combined with figure 2 , attached image 3 , attached Figure 4 And attached Figure 6 As shown, the limit assembly mainly consists of several first pin holes (not shown in the figure), several second pin holes (not shown in the figure), several first stop pins 6, and several second stop pins. 7 and several stop pin sleeves 8 constitute. In the present embodiment, the quantity of coil pipe 5 is 6, so 5 gaps are formed between 6 and coil pipe 5. Both the first pin hole and the second pin hole are opened on the fixed mold 1, and the first stop pin 6 is inserted in the first pin hole; the first pin hole is arranged on the edge of the fixed mold 1, so that the first stop pin 6 The front and rear sides of the coil pipe 5 can be limited. The second stop pin 7 is inserted into the second pin hole, and...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is: in this embodiment, in combination with the attached Figure 7 As shown, a connecting piece 12 is provided between the second retaining pins 7 of the same row, and a connecting piece 12 is also provided between the retaining pin sleeves 8 of the same row, and the connecting piece 12 is a flexible connecting piece 12, preferably with a diameter of 0.7 of wire. The thickness of the connecting piece 12 is small, which is 2-5mm. Using the connecting piece 12 with a small thickness can prevent the cross-section of the casting 14 from breaking due to the excessive thickness of the connection between the second stop pins 7, and improve the quality of die casting gradually. .

[0052] The connecting piece 12 arranged on the second stop pin 7 can support and further limit the bottom of the coil 5 on the one hand, so that the flatness of the six coils 5 arranged side by side is better, and the coil 5 is strengthened. O...

Embodiment 3

[0055] The difference between this embodiment and embodiment 1 is that: Figure 8 , attached Figure 9 , attached Figure 10 As shown, a platform 25 is formed between the two placing grooves, and a movable chamber 3 is provided in the platform 25, and a slide plate is horizontally slidably connected in the movable chamber 3, and a push rod 24 is welded to the front and rear parts of the right side of the slide plate. 24 is slidably connected in the platform 25, and the right side of the platform 25 offers a slide hole, and the right end of the push rod 24 passes through the slide hole and offsets against the left side of the fixed block 2. A first spring is also fixed on the right side of the slide plate, and the right end of the first spring is fixed on the right side wall of the movable chamber 3 .

[0056] The upper part of the positioning joint 4 is provided with a draw-in groove 27, and a vertical hole is offered on the top surface of the platform 25, and the stop bar 2...

Abstract

The invention relates to the technical field of die casting, and discloses a coiled pipe positioning tool. The coiled pipe positioning tool comprises a limiting assembly used for limiting coiled pipesand a fixing assembly, the limiting assembly comprises a plurality of first pin holes and a plurality of second pin holes, first blocking pins are detachably connected into the first pin holes, second blocking pins are detachably connected into the second pin holes and located in clearances formed among the adjacent coiled pipes, the plurality of second blocking pins are arranged into a pluralityof rows in the width direction of the coiled pipes, and every two adjacent rows of the second blocking pins are arranged in a staggered mode. According to the scheme, the coiled pipes can be prevented from deviating in the die casting process, it is guaranteed that the coiled pipes do not generate deformation exceeding machining allowance in the width direction and in the thickness direction to cause cutting machining pipe exposure, therefore, castings obtained after die casting are overall beautiful and good in consistency, casting scrap caused by cutting machining pipe exposure is reduced,and the completeness of the castings and the air tightness of the coiled pipes are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of die casting. Background technique [0002] The existing coil positioning tool is fixed by setting a clamp structure on the die-casting mold. With this positioning tool, there will be corresponding gaps in the casting after the die-casting is completed. Therefore, the gap in the casting needs to be repaired later. The rear casting is prone to large deformation, and the fixing of the clamp cannot control the movement of the coil in the thickness direction. A slight deformation or displacement of the coil during the die-casting process will cause the coil to be milled through during casting processing. It is difficult to guarantee the integrity of the casting and the airtightness of the coil. Contents of the invention [0003] The object of the present invention is to provide a coil positioning tool to solve the problem that the existing coil positioning tool in the background technology is difficult to e...
