Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a casting mold for a bimetallic composite hammerhead for a crusher. Background Technology

[0002] Bimetallic composite hammers for crushers are generally manufactured by mold casting. Before casting, the upper and lower molds need to be assembled first, and then the molten casting is poured into the assembled mold and left to cool and solidify.

[0003] In the existing casting technology, due to the presence of residual air in the mold during the molten casting process, air bubbles are formed in the molten casting. As a result, the surface of the produced composite hammerheads often has cracks, leading to lower strength. Furthermore, after cooling and solidification, the composite hammerheads are prone to getting stuck in the mold and are difficult to remove.

[0004] To address the problems of existing casting technologies where residual air in the mold during the liquid injection process often causes cracks on the surface of the composite hammer and makes it difficult to remove the composite hammer after cooling and solidification, a casting mold is designed to prevent external air from entering the mold during the liquid injection process and to eject the hammer after cooling and solidification, thereby overcoming these problems. Utility Model Content

[0005] In order to overcome the problems of existing casting technology, such as the presence of residual air in the mold during the liquid injection process, which often causes cracks on the surface of the composite hammer head, and the composite hammer head being easily stuck in the mold and difficult to remove after cooling and solidification.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment: a casting mold for a bimetallic composite hammerhead for a crusher, including a main support frame 1, an upper mold 2, a lower mold 3, a lower support frame 5, and a positioning frame 10. The upper mold 2 and the lower mold 3 are housed within the main support frame 1, and together they form a mold for casting the composite hammerhead. The lower support frame 5 is fixedly installed at the upper bottom of the main support frame 1, and the positioning frame 10 is fixedly installed at the upper top of the upper mold 2. The surface of the main support frame 1 is provided with a positioning component for fixing the upper mold 2 and the lower mold 3, and the surface of the positioning frame 10 is provided with a liquid injection component for injecting casting liquid. The positioning component of this bimetallic composite hammerhead casting mold is automatically removed from the mold after the hammerhead has cooled and formed, avoiding the situation where the hammerhead is stuck in the mold and difficult to remove. During the vacuuming and liquid injection process, the liquid injection component prevents air from entering the mold, thereby avoiding the problem of cracks appearing on the surface of the hammerhead due to air bubbles.

[0023] Please see Figure 1 and Figure 2 In this embodiment, the positioning component includes a fixed support foot 4, which is fixedly installed at the top of the main support frame 1. The upper mold 2 is fixedly installed at the lower end of the fixed support foot 4. Cylinders 6 are fixedly installed at the four corners of the lower end of the lower support frame 5. The output end of the cylinder 6 passes through the lower support frame 5 and is fixedly connected to the upper support frame 7. The lower mold 3 is fixedly installed at the upper end of the upper support frame 7. A top block 8 is fixedly connected to the upper end of the lower support frame 5. A top block 9 is slidably connected to the lower end of the lower mold 3. The top block 8 is used to lift the top block 9, and the top block 9 is used to lift the formed composite hammer head.

[0024] Please see Figure 2 , Figure 3 and Figure 5In this embodiment, the injection assembly includes a quick connector 11, which is fixedly installed on the upper end of the positioning frame 10. A tube 12 is slidably connected inside the quick connector 11. An injection tube 13 is provided through the upper end of the upper mold 2. An annular locking block 14 is fixedly connected to the upper end of the injection tube 13. A sliding tube 15 is slidably connected to the center of the annular locking block 14. The upper end of the sliding tube 15 is located above the injection tube 13, and the lower end of the sliding tube 15 is located inside the injection tube 13. Both the upper and lower ends of the injection tube 13 are provided with annular protrusions. A spring 17 is fitted on the surface of the upper mold 3. The spring 17 is located below the annular protrusion at the upper end of the slide tube 15. The spring 17 is used to lift the slide tube 15 upward. The lower end surface of the slide tube 15 is provided with a liquid outlet 16. The liquid outlet 16 is located above the annular protrusion at the lower end of the slide tube 15. The annular locking block 14 is used to block the liquid outlet 16. Heat-conducting blocks 18 are fixedly connected to both sides of the upper mold 2 and the lower mold 3. The heat-conducting blocks 18 are provided with openings. Multiple sets of heat dissipation fins 19 are provided in the openings of the heat-conducting blocks 18. A shaping tube 20 is provided through the surface of the heat dissipation fins 19.

[0025] In use, first, the upper mold 2 is fixedly installed at the lower end of the fixed support foot 4, and then the lower mold 3 is fixedly installed at the upper end of the upper support frame 7. This completes the preparation work before casting. Then, the cylinder 6 is started, and the upper support frame 7 fixedly installed at the output end of the cylinder 6 moves upward, so that the lower mold 3 fixedly installed at the upper end of the upper support frame 7 is combined with the upper mold 2. After the upper mold 2 and the lower mold 3 are combined, the liquid injection process can be carried out. The casting liquid is injected from the liquid injection pipe 13 at the upper end of the upper mold 2, and then wait for the casting liquid to cool and solidify. After the casting is completed, the cylinder 6 is started in reverse. The cylinder 6 drives the upper support frame 7 to move downward. The top block 8 fixedly installed at the upper end of the lower support frame 5 lifts the top block 9 slidably installed at the lower end of the lower mold 3. In this way, the formed composite hammer head can be ejected from the mold, thereby quickly removing the hammer head.

[0026] In use, after the upper mold 2 and lower mold 3 are assembled, the connecting pipe of the vacuum pump is first inserted into the quick connector 11. During the insertion process, the insert 12 moves downwards, causing the slide tube 15 to move downwards. The upper end of the slide tube 15 protrudes and blocks the upper end of the injection tube 13. Under the action of the vacuum pump, the air inside the upper mold 2 and lower mold 3 is drawn out from the liquid outlet 16 on the surface of the slide tube 15. Then, the connecting pipe of the vacuum pump is pulled out. After the connecting pipe of the vacuum pump is pulled out, the slide tube 15 is bounced upwards under the action of the spring 17. The annular protrusion at the lower end of the tube 15 is blocked by the annular locking block 14 at the upper end of the injection tube 13, and the outlet 16 is also blocked by the annular locking block 14. In this way, after the connecting tube is pulled out, the outside air cannot enter the mold, ensuring that the upper mold 2 and the lower mold 3 are in a vacuum state. Then, the connecting tube of the casting liquid is inserted into the quick connector 11, and the injection liquid enters the upper mold 2 and the lower mold 3 through the outlet 16. This completes the injection process. During the vacuuming and injection process, air cannot enter the mold, thus ensuring the casting quality of the composite hammer.

[0027] During the cooling and molding process, the heat inside the mold is transferred to the outside air through the heat-conducting block 18. Multiple sets of heat sinks 19 are provided in the opening of the heat-conducting block 18. The heat sinks 19 increase the contact area with the air, thereby making the casting liquid inside the mold cool more quickly. A shaping tube 20 is provided through the surface of the heat sink 19. The shaping tube 20 is used to prevent the heat sink 19 from deforming when exposed to high temperature and to avoid the heat sinks 19 from contacting each other and affecting the heat dissipation effect.

[0028] Through the above steps, the casting mold of the bimetallic composite hammerhead of the crusher can quickly cool and solidify the molten metal. After the hammerhead is cooled and solidified, it will be automatically removed from the mold, avoiding the situation where the hammerhead is stuck in the mold and difficult to remove. During the vacuuming and liquid injection process, the liquid injection port of the mold can be automatically blocked, preventing air from entering the mold and thus avoiding the problem of cracks on the surface of the hammerhead caused by air bubbles.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 invention.
