[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Reference Figure 1-5 , please refer to Figure 1-Figure 5 ,in, Figure 1 This is a three-dimensional structural schematic diagram of a positioning device for steel pin compression molding proposed by the utility model; Figure 2 This is a schematic diagram of a cutaway three-dimensional structure of a positioning device for steel pin compression molding proposed by the utility model; Figure 3 This is a schematic diagram of the three-dimensional structure of the internal components of a positioning device for steel pin compression molding proposed by the utility model; Figure 4 The three-dimensional structure of the positioning assembly of the positioning device for steel pin molding proposed by the utility model is disassembled Figure 1 ; Figure 5 The three-dimensional structure of the positioning assembly of the positioning device for steel pin molding proposed by the utility model is disassembled Figure 2A positioning device for steel pin die pressing comprises: a steel pin die pressing platform 1, a leg 2 is fixedly installed at the bottom of the steel pin die pressing platform 1, a support 3 is fixedly installed on the steel pin die pressing platform 1, a hydraulic press 5 is fixedly installed at the bottom of the support 3, a forming cylinder 7 is arranged at the bottom of the hydraulic press 5, a side connecting piece 71 is fixedly connected to the side of the forming cylinder 7, an electric telescopic rod 6 is fixedly installed on the upper side of the steel pin die pressing platform 1, an output end of the electric telescopic rod 6 is fixedly connected to the side connecting piece 71, positioning holes 73 are evenly distributed on the side wall of the forming cylinder 7, a fixing column 8 is arranged on the inner side of the forming cylinder 7, a control switch 4 is installed on the side of the support 3, the control switch 4 is electrically connected to the electric telescopic rod 6 and the hydraulic press 5 respectively, and a positioning component 10 is installed inside the steel pin die pressing platform 1.

[0024] In this method, the positioning assembly 10 includes a mounting slide 101, which is fixedly mounted on the inner side of the steel pin molding platform 1, a nut 102 is threadedly mounted on the outer end of the mounting slide 101, a movable slide column 106 is slidably mounted on the inner side of the mounting slide 101, a permanent magnet 107 is fixedly mounted on the outer end of the movable slide column 106, and an electromagnetic coil 105 is fixedly mounted on the inner side of the nut 102.

[0025] By the arrangement in the above manner, by energizing the electromagnetic coil 105 in the forward and reverse directions, the magnetic poles between the electromagnetic coil 105 and the permanent magnet 107 can be reversed. When the magnetic poles of the electromagnetic coil 105 and the permanent magnet 107 are the same, the permanent magnet 107 is subjected to the magnetic repulsion force, and under the action of the magnetic repulsion force, the movable slide column 106 can be pushed to be inserted into the positioning hole 73 on the side wall of the forming tube 7, thereby achieving the fixed positioning effect on the forming tube 7. When the magnetic poles of the electromagnetic coil 105 and the permanent magnet 107 are opposite, the movable slide column 106 is driven to retract and exit the positioning hole 73 under the action of the magnetic attraction force, thereby releasing the limit on the forming tube 7. At this time, the height of the upper side of the forming tube 7 can be adjusted by starting the electric telescopic rod 6.

[0026] In this embodiment, the outer diameter of the movable sliding column 106 is matched with the inner diameter of the positioning hole 73 .

[0027] In this embodiment, the forming tube 7 is slidably connected to the steel pin molding platform 1 and the forming tube 7 slides through the lower side of the steel pin molding platform 1 , and the upper end of the forming tube 7 is fixedly connected with a flared port 72 .

[0028] By means of the above-mentioned arrangement, the expansion opening 72 is arranged to facilitate the feeding of materials into the forming tube 7 .

[0029] In this embodiment, the fixed column 8 is in sliding contact with the inner wall of the forming tube 7, and a plurality of fixed connecting rods 9 are fixedly connected between the bottom of the fixed column 8 and the bottom of the steel pin molding platform 1.

[0030] By configuring in the above manner, the plurality of fixed connecting rods 9 are configured to enhance the fixed connection strength of the fixed column 8, so that the fixed column 8 has sufficient pressure bearing capacity, thereby enabling the fixed column 8 to withstand pressure during the die-casting process of the hydraulic press 5.

[0031] In this embodiment, a lead wire 103 is disposed outside the nut 102 , the lead wire 103 is electrically connected to the electromagnetic coil 105 , and a series loop wire 104 is connected in series outside the lead wire 103 .

[0033] The working principle of a positioning device for steel pin die pressing provided by the utility model is as follows:

[0034] When in use, the upper side height of the forming cylinder 7 is determined according to the height of the steel pin mold to be produced. After the height is determined, the electromagnetic coil 105 is energized in the reverse direction, and the magnetic attraction force is used to drive the movable sliding column 106 to withdraw from the limit range of the positioning hole 73 on the side wall of the forming cylinder 7. After the electric telescopic rod 6 is subsequently started to adjust the top height of the forming cylinder 7 to the corresponding height, the electromagnetic coil 105 is energized in the forward direction, and the magnetic repulsion force is used to push the movable sliding column 106 to be inserted into the positioning hole 73, thereby achieving the fixed positioning effect on the forming cylinder 7. Subsequently, the production raw materials are added to the forming cylinder 7 through the expansion mouth 72, and the hydraulic press 5 is started. Pressure is applied to the forming cylinder 7 at the output end of the hydraulic press 5 to squeeze the production raw materials into shape to generate a steel pin mold. Subsequently, the electromagnetic coil 105 is energized in the reverse direction to contact the limit of the forming cylinder 7. At this time, the electric telescopic rod 6 contracts, driving the end of the forming cylinder 7 to descend, so that the formed steel pin mold protrudes from the end of the forming cylinder 7, and the generated steel pin mold can be taken out at this time.

[0035] Compared with the related art, the positioning device for steel pin die pressing provided by the utility model has the following beneficial effects:

[0036] The utility model provides a positioning device for steel pin die pressing. In the utility model, the hydraulic press 5, the forming cylinder 7 and the fixed column 8 are arranged on the same vertical axis. During the steel pin die pressing process, the forces are all applied to the axis position, the forces are balanced, and the structure is stable. At the same time, the forming cylinder 7 is adjusted to move up and down through the cooperation of the positioning component 10 and the electric telescopic rod 6, which is suitable for processing steel pin molds of different heights.
