Description

Technical Field

[0001] This utility model relates to the field of mold cooling machine technology, specifically to a die casting mold cooling machine. Background Technology

[0002] Excessive die-casting mold temperature can cause premature mold cracking, severe wear of moving mechanisms such as slides and ejector pins, and casting quality problems such as hot cracking, warping, surface porosity, blistering, flash, and carbon buildup. Conversely, insufficient die-casting mold temperature can cause casting quality problems such as incomplete filling, excessive shrinkage, and cold cracks. Die-casting mold temperature is a crucial process parameter in die-casting, affecting casting quality, production efficiency, and casting costs.

[0003] According to a published specification (Publication No.: CN104057056B), a die-casting mold cooling machine includes a filter, a water tank, a constant pressure water pump, a flow sensor, a timer, and a ball valve. The filter and water tank are connected sequentially. The outlet of the constant pressure water pump is connected to multiple water pipelines. A flow sensor and a timer are installed on each water pipeline. The constant pressure water tank is controlled by a frequency converter to achieve constant and adjustable water pressure. A ball valve is installed at the end of each water pipeline. However, the above device, through the cooperation of components such as the flow sensor, timer, and ball valve, is difficult to achieve the effect of fixing the mold, making it difficult to stably fix it in a suitable position, and making it difficult to ensure the mold accuracy and consistency during the die-casting process. It needs to be improved. Utility Model Content

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the force of the bidirectional reciprocating screw driven by the motor to rotate cooperates with the threaded block, fixed block and pressure plate in the fixing device. This achieves the effect of fixing the mold by displacing the threaded block to drive the rotating rod to rotate, then driving the fixed block to move upward, and finally driving the pressure plate to move. This achieves the effect of fixing the mold, which can be stably fixed in a suitable position to ensure the mold accuracy and consistency in the die casting process.

[0016] 2. In this utility model, the force of the rotating rod driven by the bidirectional reciprocating screw rotation cooperates with the mounting plate, support rod, and spring pump in the fixing device to achieve the effect of displacement through the support block displacement telescopic tube, which in turn drives the connecting pipe displacement, and the connecting pipe displacement drives the nozzle displacement. This expands the cooling range for cooling the mold and ensures that the coolant can flow precisely to specific parts of the mold for cooling, thereby improving the cooling efficiency and uniformity.

[0028] Example 1

[0029] Reference Figures 1-5The first embodiment of this utility model proposes a die-casting mold cooling machine, including a protective plate 101, and a fixing plate 102 fixedly connected to the side of the protective plate 101.

[0030] A fixing device 2 is provided on the side of the protective plate 101. The fixing device 2 includes a motor 201, which is fixedly connected to the side of the fixing plate 102. The output shaft of the motor 201 is fixedly connected to a bidirectional reciprocating lead screw 202. A threaded block 203 is threadedly connected to the circumferential surface of the bidirectional reciprocating lead screw 202. A rotating rod 204 is rotatably connected to the side of the threaded block 203. A fixing block 205 is rotatably connected to the end of the rotating rod 204 away from the threaded block 203. A pressure plate 206 is fixedly connected to the bottom of the fixing block 205.

[0031] A limit rod 207 passes through the side of the threaded block 203. One end of the limit rod 207 is fixedly connected to the side of the fixing plate 102. By limiting the threaded block 203 through the limit rod 207, the range of motion can be restricted, thus avoiding damage to the mechanical parts due to operational errors or abnormal conditions.

[0032] In this embodiment, the application uses a motor 201 to drive a bidirectional reciprocating screw 202 to rotate. The rotation of the bidirectional reciprocating screw 202 then causes two threaded blocks 203 to move towards each other. The threaded blocks 203 are limited by a limiting rod 207 on their side. The displacement of the threaded blocks 203 causes the rotating rod 204 to rotate. The rotation of the rotating rod 204 then causes the fixed block 205 to move upward. The displacement of the fixed block 205 causes the pressure plate 206 to move, thus achieving the function of fixing the mold.

[0034] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

A spring pump 211 is fixedly connected to the top of the protective plate 101. A positioning plate 213 is fixedly connected to the inner wall of the spring pump 211. A partition 214 is provided on the side of the positioning plate 213. A fixing rod 217 is fixedly connected to the top of the partition 214. A positioning rod 218 passes through the side of the spring pump 211. A telescopic tube 220 passes through the side of the spring pump 211. A connecting tube 221 passes through the end of the telescopic tube 220 away from the spring pump 211. A nozzle 222 passes through the end of the connecting tube 221 away from the telescopic tube 220.

[0036] The cooling structure includes a moving structure, which includes a gear 224. The gear 224 is fixedly connected to the circumferential surface of the rotating rod 208. A mounting plate 225 is fixedly connected to the side of the protective plate 101. A reciprocating screw 227 passes through the side of the mounting plate 225. A threaded sleeve 228 is threadedly connected to the circumferential surface of the reciprocating screw 227. A support block 223 is fixedly connected to the side of the threaded sleeve 228. A gear disk 226 is fixedly connected to the circumferential surface of the reciprocating screw 227. A feed pipe 212 passes through the top of the spring pump 211.

[0037] The end of the support block 223 away from the threaded sleeve 228 is fixedly connected to the telescopic end of the telescopic tube 220. The side of the gear 224 meshes with the side of the gear disk 226. One end of the positioning rod 218 is set as an inclined surface. The top of the fixing rod 217 is set as an inclined surface. The top of the partition 214 passes through the limit post 215. The two ends of the limit post 215 are fixedly connected to the inner wall of the spring pump 211.

[0038] The bottom of the threaded sleeve 228 is fixedly connected to a slide rod 229. The end of the slide rod 229 away from the threaded sleeve 228 is slidably connected to the top of the protective plate 101. The fixed rod 217 is located on the movement trajectory of the positioning rod 218, and the positioning rod 218 is located on the movement trajectory of the roller 210. The design of the roller 210 allows the spring pump 211 to automatically spray water to cool the mold.

[0039] A compression spring 219 is fixedly connected to the side of the spring pump 211. The end of the compression spring 219 away from the spring pump 211 is fixedly connected to the outer surface of the positioning rod 218. The initial state of the compression spring 219 is a relaxed state. The design of the compression spring 219 can make the positioning rod 218 automatically reset, reducing manual intervention.

[0040] A reset spring 216 is fixedly connected to the bottom of the partition 214. The end of the reset spring 216 away from the partition 214 is fixedly connected to the inner wall of the spring pump 211. The initial state of the reset spring 216 is a relaxed state. The design of the reset spring 216 enables the partition 214 to automatically reset, thereby improving the efficiency and uniformity of cooling.

[0041] Compared to Embodiment 1, further, the bidirectional reciprocating screw 202 rotates, driving the rotating rod 208 to rotate. The rotating rod 208 then drives the support rod 209 to rotate, which in turn drives the roller 210 to rotate. The roller 210 then presses the inclined surface of the positioning rod 218, causing the positioning rod 218 to displace and press the inclined surface of the fixing rod 217. This causes the fixing rod 217 to move the partition plate 214. At this point, a notch appears on the side of the positioning plate 213, allowing the coolant at the top of the spring pump 211 to flow through the notch to the bottom of the spring pump 211. The coolant is then sprayed out from the nozzle 222 through the telescopic pipe 220 and the connecting pipe 221, thus applying pressure to the mold. Cooling is achieved by rotating the lever 208, which in turn drives the gear 224 to rotate. The gear 224 then drives the gear disk 226 to rotate, which in turn drives the reciprocating screw 227 to rotate. The reciprocating screw 227 then drives the threaded sleeve 228 to move. The threaded sleeve 228 is limited by the sliding rod 229 at its bottom. The displacement of the threaded sleeve 228 then drives the support block 223 to move. The displacement of the support block 223 then drives the telescopic tube 220 to move. The displacement of the telescopic tube 220 then drives the connecting tube 221 to move. The displacement of the connecting tube 221 then drives the nozzle 222 to move, thus expanding the cooling range.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
