Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and in particular to a die casting mold steering extrusion device. Background Technology

[0002] In die casting, shrinkage cavities or gas pores easily form during the solidification of molten metal. The conventional solution is to use an extrusion pin to apply continuous pressure to a localized area during the solidification stage, pushing the molten metal to fill the shrinkage gaps, significantly reducing internal porosity and improving the density of the casting. However, for some long and slender parts that require tubular features at their ends, the hydraulic cylinder of the extrusion mechanism is located inside the mold frame when the extrusion pin is used to extrude the end of the die. This occupies a large mold thickness, resulting in a heavy and bulky mold that is difficult to match with the die casting machine, making processing difficult. Utility Model Content

[0030] Reference Figure 1 According to an embodiment of the present invention, a die-casting mold steering extrusion device includes a mold frame 100 and a template 120. The template 120 is mounted on the mold frame 100 and has a forming cavity 124 for forming a workpiece 121. The mold frame 100 is provided with a transmission mechanism 110, which includes a first slider 111 and a second slider 112. The first slider 111 is slidably connected to the mold frame 100, and the side wall of the first slider 111 has a protruding guide rail 115. The side wall of the second slider 112 has a recessed first guide groove 116. The end of the second slider 112 is provided with a pressure pin 117. The guide rail 115 is embedded in the first guide groove 116. On the one hand, the sliding connection between the outer side of the first slider 111 and the second slider 112 facilitates installation and disassembly; on the other hand, the depth of the first guide groove 116 is equal to half the thickness of the second slider 112, which enables the first slider 111 and the second slider 112 to cooperate stably and ensure good transmission stability. Furthermore, when the first slider 111 moves toward the second slider 112 along the length direction of the mold frame 100, it can cause the pressure pin 117 to move along the thickness direction of the mold frame 100 and press against the workpiece 121. That is, the moving direction of the first slider 111 is perpendicular to the moving direction of the second slider 112. The first slider 111 and the second slider 112 can be moved in different directions through the transmission mechanism 110, thereby reducing the space occupied by the mold thickness, reducing the mold volume, and improving the adaptability of the die casting machine.

[0031] Reference Figure 2It is understandable that when the pressure pin 117 is inserted into the forming cavity 124, the outer peripheral wall of the pressure pin 117 and the inner peripheral wall of the forming cavity 124 can form the tube portion 123 of the workpiece 121. Furthermore, the mold frame 100 is provided with a first guide sleeve 107, and the template 120 is provided with a second guide sleeve 122. The first guide sleeve 107 and the second guide sleeve 122 cover the outer periphery of the pressure pin 117, and the pressure pin 117 is slidably connected to the first guide sleeve 107 and the second guide sleeve 122 to ensure that the pressure pin 117 can move stably along a preset trajectory, ensuring casting accuracy.

[0032] It is understood that the transmission mechanism 110 also includes a hydraulic cylinder 113 and a drive rod 114, with the two ends of the drive rod 114 detachably connected to the first slider 111 and the piston rod of the hydraulic cylinder 113, respectively. It is understood that the mold frame 100 has a mounting groove 105, within which the first slider 111 and the drive rod 114 are located, allowing the transmission mechanism 110 to be compactly arranged on the mold frame 100, thus saving space. It is understood that the mold frame 100 has a mounting seat 109 at one end along its length, and the hydraulic cylinder 113 is mounted on the end of the mounting seat 109 opposite to the mold frame 100. It is understandable that the length direction of the guide rail 115 is inclined to the moving direction of the first slider 111, and along the length direction of the mold frame 100, the guide rail 115 extends from the oil cylinder 113 toward the first slider 111 in a direction away from the mold plate 120, so that when the piston rod of the oil cylinder 113 extends, the guide rail 115 can guide the second slider 112 to move and drive the pressure pin 117 to move into the mold cavity to realize the extrusion process.

[0033] Reference Figure 2 It is understood that the mold frame 100 is provided with a guide block 101 and a pressure plate 102. The guide block 101 is fixedly installed in the mounting groove 105. The pressure plate 102 is detachably installed and covers the guide block 101. There is a connecting cavity 104 between the pressure plate 102 and the guide block 101. The connecting cavity 104 passes through the guide block 101 along the length direction of the template 120. The first slider 111 slides in the connecting cavity 104.

[0034] Reference Figure 3 The outer peripheral wall of the first slider 111 is provided with a plurality of recessed oil grooves 119. The oil grooves 119 are provided on the outer wall of the slide rail for contacting the inner wall of the guide block 101 and the outer wall of the first slider 111 for contacting the pressure plate 102. The oil grooves 119 can store lubricating oil, thereby providing good lubrication between the first slider 111 and the guide block 101, and between the first slider 111 and the pressure plate 102, thereby reducing the moving resistance and improving the transmission efficiency.

[0035] It is understood that the connecting cavity 104 has a second guide groove 118, and the second slider 112 slides within the second guide groove 118. Specifically, the second guide groove 118 is recessed into the inner wall of the connecting cavity 104, which ensures the stable movement of the second slider 112 and improves transmission stability. Furthermore, the second slider 112 is cylindrical, making it easy to process both the second slider 112 and the second guide groove 118. Further, the pressure plate 102 has a clearance groove 103, which communicates with the second guide groove 118 and extends through the pressure plate 102 along the thickness direction of the mold frame 100, so that when the second slider 112 is withdrawn from the mold cavity, it can be embedded in the clearance groove 103, avoiding interference.

[0036] Furthermore, a limiting platform 106 is provided in the mounting groove 105. The limiting platform 106 is located at the end of the first slider 111 away from the oil cylinder 113. The limiting platform 106 can limit the movement range of the first slider 111, prevent the first slider 111 from exceeding the preset stroke when it moves, and avoid collision or interference.

[0037] Understandably, during installation, the second slider 112, with the pressure pin 117 already installed, is first placed in the second guide groove 118. Then, the first slider 111 is inserted into the connecting cavity 104, and the guide rail 115 is inserted into the first guide groove 116, causing the first slider 111 and the second slider 112 to move together. The pressure plate 102 is then installed on the guide block 101. Furthermore, a drive rod 114 is installed at the end of the first slider 111, and the drive rod 114 is connected to the hydraulic cylinder 113.

[0038] It is understood that the top of the second slider 112 has a connecting hole 108, and the inner circumferential wall of the connecting hole 108 has threads. During disassembly, an auxiliary tool is used to connect the second slider 112 through the connecting hole 108. When the first slider 111 is pulled out of the connecting cavity 104 and the guide rail 115 disengages from the first guide groove 116, the second slider 112 can be restrained by the auxiliary tool to prevent it from falling. The second slider 112 can also be pulled out by the auxiliary tool to complete the disassembly process. It is understood that since the pressure plate 102 has a clearance groove 103, the second slider 112 can be pulled out from the clearance groove 103 during disassembly. Therefore, when replacing the pressure pin 117 or performing maintenance, it is not necessary to remove the pressure plate 102, which simplifies the operation steps and improves the operation efficiency.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
