Description

Technical Field

[0001] This utility model relates to the field of crusher hammer casting technology, specifically a casting mold for preparing bimetallic composite hammers. Background Technology

[0002] To meet current needs, crusher hammers are generally bimetallic composite hammers. A patent document, CN216502292U, entitled "A Casting Mold for a Bimetallic Composite Hammer for Crusher," describes a method where a second movable mold is brought closer to a first mold to connect them. A first molten metal is then injected into the cavities of both molds through an inclined gating system. After cooling for a certain period, a binder is injected into the cavities again through the gating system. After further cooling, a second molten metal is injected into the cavities through an inclined gating system (higher than the first gating system). After holding at a certain temperature for a period, the casting of the bimetallic composite hammer is completed. Finally, moving the second mold allows separation of the mold and mold, enabling the hammer to be removed. This technical solution is applicable to the casting of bimetallic composite hammers for crushers and facilitates the movement of the second mold, improving the ease of separation.

[0003] The technical solution also feeds the molten metal into the first sprue, the third sprue, and the second sprue at the top through a detachable feed pipe and a feed hopper. However, in actual use, it was found that the first and third sprues, which are inclined on both sides, have no sealing structure. When the liquid level of the molten metal is higher than the first and third sprues, it will enter the first and third sprues respectively, resulting in protruding structures on both sides after the hammer head is formed, which in turn affects the forming of the hammer head.

[0004] A search revealed a patent document with publication number CN221983876U, entitled "A Casting Mold for a Bimetallic Composite Hammerhead of a Mining Crusher." This patent improves upon the technical solution in CN216502292U, solving the problems of inconvenience in limiting the mold after mold closing and low product forming efficiency under natural cooling. However, it still does not solve the problem that there is no sealing structure for the inclined sprue 1 and sprue 3 on both sides. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a casting mold for preparing bimetallic composite hammerheads, thus solving the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a casting mold for preparing bimetallic composite hammerheads, comprising a base, a fixed mold and a lead screw provided on the top of the base, and a slide frame slidably connected to the top of the base in the front-back direction, the slide frame being screwed onto the lead screw, the slide frame being connected to a movable mold, and cavities provided on opposite sides of the fixed mold and the movable mold.

[0007] Both the fixed mold and the movable mold have inclined flow channels that communicate with the cavity on both sides, and the right inclined flow channel is higher than the left inclined flow channel. Both the fixed mold and the movable mold have slots that communicate with the inclined flow channels on both sides.

[0008] Both sides of the slot are provided with a feed pipe, and the top of the feed pipe is connected to a connecting pipe. A sealing rod is attached to the feed pipe and connected to a limiting component on the feed pipe.

[0009] Both the fixed mold and the movable mold have vertical flow channels at their tops, and the vertical flow channels are inserted into feed hoppers that are in contact with the tops of both the fixed mold and the movable mold.

[0010] Preferably, the limiting component includes insertion holes on both sides of the top of the sealing rod, and the feed tube is provided with a protrusion, through which an insertion rod is inserted into one of the insertion holes.

[0011] Preferably, a spring connects the insertion rod and the protrusion.

[0012] Preferably, the end of the sealing rod is provided with a handle, and when the sealing rod blocks the oblique flow channel, the handle contacts the protrusion.

[0013] Preferably, the bottom of the sealing rod is integrally formed with a protrusion, and the protrusion is slidably connected to the feed pipe, and the bottom of the inclined channel is provided with a groove that matches the protrusion.

[0014] Preferably, the base has a drawer at its bottom, and the drawer has a support at its bottom.

[0015] This invention provides a casting mold for manufacturing bimetallic composite hammerheads. Compared with the prior art, it has the following advantages:

[0016] 1. The casting mold used to prepare the bimetallic composite hammerhead has a feed pipe that is stably inserted through a slot. Molten metal is injected through a connecting pipe. After flowing through the feed pipe, the molten metal flows into the cavity through an inclined channel. When the inclined channel is not needed for injection, the sealing rod moves along the feed pipe into the inclined channel and aligns with the cavity to seal the inclined channel. This ensures that the molten metal level is higher than the inclined channels on both sides, preventing it from entering the inclined channels and avoiding protruding structures on both sides of the hammerhead after molding, thus ensuring the hammerhead is formed.

[0017] 2. The casting mold for preparing the bimetallic composite hammerhead has a drawer, which allows the removed feed pipe and feed hopper to be temporarily placed in the drawer after the mold is opened. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: A casting mold for preparing a bimetallic composite hammerhead includes a base 1, a fixed mold 2 and a lead screw 3 are provided on the top of the base 1, and a slide 4 is slidably connected to the top of the base 1 in the front-back direction. The slide 4 is screwed onto the lead screw 3. The slide 4 is connected to a movable mold 5, and cavities 6 are provided on opposite sides of the fixed mold 2 and the movable mold 5.

[0026] Both sides of the fixed mold 2 and the movable mold 5 are provided with inclined flow channels 7 that communicate with the cavity 6, and the right inclined flow channel 7 is higher than the left inclined flow channel 7, for injecting different molten metals respectively. Both sides of the fixed mold 2 and the movable mold 5 are provided with slots 8 that communicate with the inclined flow channels 7, so as to facilitate the stable placement of the feed pipe 11.

[0027] Both sides of the slot 8 are provided with feed pipes 11, and the top of the feed pipe 11 is connected to a connecting pipe 12. A sealing rod 13 is attached to the feed pipe 11, and the sealing rod 13 is connected to the limiting component provided on the feed pipe 11.

[0028] Both the fixed mold 2 and the movable mold 5 have vertical flow channels 9 at their tops, and the vertical flow channels 9 are inserted into feed hoppers 10 that are in contact with the tops of both the fixed mold 2 and the movable mold 5.

[0029] The limiting component includes insertion holes 14 on both sides of the top of the sealing rod 13. A protrusion 15 is provided on the feed pipe 11. An insertion rod 16 is inserted through the protrusion 15 and inserted into one of the insertion holes 14. When inserted into the lower insertion hole 14, it blocks the inclined flow channel 7. When inserted into the upper insertion hole 14, it does not affect the injection of molten metal and is still located in the feed pipe 11.

[0030] A spring 17 connects the insertion rod 16 and the protrusion 15, which serves as a connection to prevent the insertion rod 16 from being lost.

[0031] The end of the sealing rod 13 is provided with a handle 18, which makes it easy to pull the sealing rod 13. When the sealing rod 13 blocks the inclined flow channel 7, the handle 18 contacts the protrusion 15, which helps the user to position the sealing rod 13.

[0032] The bottom of the sealing rod 13 is integrally formed with a protrusion 19, and the protrusion 19 is slidably connected to the feed pipe 11. The bottom of the inclined channel 7 is provided with a groove that matches the protrusion 19, so that the sealing rod 13 can be guided when it moves, thereby ensuring that its insertion hole 14 is always on the upper side, further helping the user to insert the rod 16 into the insertion hole 14.

[0033] The second embodiment differs from the first embodiment in that: a drawer 20 is provided at the bottom of the base 1, and a support 21 is provided at the bottom of the drawer 20, which facilitates temporary storage of the removed feed pipe 11 and feed hopper 10 after the mold is opened.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] By rotating the lead screw 3, the slide 4 drives the movable mold 5 to move and fit against the fixed mold 2. Then, the feed pipes 11 on both sides are inserted through the slot 8, and the feed hopper 10 is inserted through the vertical flow channel 9. Next, the first molten metal is injected through the left connecting pipe 12, which enters the cavity 6 along the left feed pipe 11 and the inclined flow channel 7. After cooling for a certain period of time, the binder is injected through the left connecting pipe 12. After injection, the liquid level is about to touch the left inclined flow channel 7, which allows the sealing rod 13 to move down and block the left inclined flow channel 7. After cooling for a period of time, the second molten metal is injected through the right connecting pipe 12, which enters the cavity 6 along the right feed pipe 11 and the inclined flow channel 7. The sealing rod 13 prevents the second molten metal from entering the left inclined channel 7. After a certain amount is injected, the liquid level will be about to contact the right inclined channel 7. At this point, the sealing rod 13 can be moved down to block the right inclined channel 7. Finally, the second molten metal is injected through the feed hopper 10 and the vertical channel 9. After a certain amount is injected, the cavity 6 is filled. At this point, the right sealing rod 13 prevents the second molten metal from entering the right inclined channel 7. After a period of heat preservation, the casting of the bimetallic composite hammer head is completed. When the mold is opened, the feed pipe 11 and the feed hopper 10 are removed and temporarily placed in the drawer 20. Then the movable mold 5 can be moved to separate the movable mold 5 from the fixed mold 2 and the hammer head can be removed.
