[0047] When the shaping mold 6 needs to be replaced, the clamping drive motor 11 is electrically connected to the external power supply, and the clamping drive motor 11 is powered to drive the transmission gear 10 to rotate. The rotation of the transmission gear 10 drives the meshing transmission rack 9 to move. The movement of the transmission rack 9 drives the connecting rod 8 to move. The movement of the connecting rod 8 drives the splint 7 to move. The splint 7 is connected to the fixed table 1 and the shaping mold 6 through a sliding connection, so that the splint 7 is separated from the shaping mold 6 after moving, and the shaping mold 6 can be replaced.

[0048] Preferably, the four end corners of the top of the fixed platform 1 are fixed with support columns 2, the outer side of the top of the support column 2 is slidably connected with a guide sleeve 3, and the inside of the guide sleeve 3 is provided with a through groove, the top of the guide sleeve 3 is fixed with a fixed shell 4, and the fixed shell 4 is installed with an adjustment mechanism for driving the support column 2 to rise and fall;

[0049] Specifically, the adjustment mechanism includes a rotating shaft 18, a limit plate 19, a first bevel gear 20, a second bevel gear 21, a transmission shaft 22 and a lifting threaded rod 23.

The bottom end of the lifting threaded rod 23 is threadedly connected to the support column 2, so that the support column 2 can be lifted and lowered by the rotation of the lifting threaded rod 23. A driving component for driving the rotating shaft 18 to rotate is also installed inside the fixed shell 4;

[0051] When it is necessary to adjust the height of the support column 2, the rotation of the rotating shaft 18 drives the first bevel gears 20 on both sides to rotate, and the rotation of the first bevel gear 20 drives the second bevel gear 21 to rotate, so that the second bevel gears 21 on both sides rotate in the opposite direction, and the rotation of the second bevel gear 21 drives the transmission shaft 22 to rotate, and the rotation of the transmission shaft 22 drives the rotation of the lifting threaded rod 23, and the lifting threaded rod 23 on one side and the lifting threaded rod 23 on the other side have opposite thread rotation directions, so that when the lifting threaded rod 23 rotates, it can simultaneously drive the threaded support column 2 to be lifted and lowered, thereby adjusting the height of the fixed shell 4.

[0052] Further, the driving assembly includes a lifting drive motor 12, a first connecting gear 13, a second connecting gear 14, a connecting shaft 15, a transmission worm 16 and a transmission worm wheel 17. The lifting drive motor 12 is fixed to the fixed shell 4, and the output end of the lifting drive motor 12 is connected to the first connecting gear 13, and the top end of the first connecting gear 13 is meshedly connected to the second connecting gear 14, so that the second connecting gear 14 can be driven to rotate by the rotation of the first connecting gear 13. A connecting shaft 15 is fixed inside the second connecting gear 14, and the connecting shaft 15 is rotationally connected to the fixed shell 4, so that the rotation of the connecting shaft 15 can be more stable;

[0053] A transmission worm 16 is arranged on the outer sides of both ends of the connecting shaft 15, and the two transmission worms 16 have the same spiral rotation direction, so that the two transmission worms 16 with the same spiral rotation direction can be driven to rotate simultaneously by the rotation of the connecting shaft 15, and a transmission worm wheel 17 is meshedly connected to the top of the transmission worm 16, and the transmission worm wheel 17 is fixed on the outer side of the rotating shaft 18, so that the rotating shaft 18 can be driven to rotate by the rotation of the connecting shaft 15;

[0054] When the rotating shaft 18 needs to rotate, the lifting drive motor 12 is electrically connected to the external power supply, so that the lifting drive motor 12 is energized and drives the first connecting gear 13 to rotate, the first connecting gear 13 rotates to drive the second connecting gear 14 to rotate, the second connecting gear 14 rotates to drive the connecting shaft 15 to rotate, the connecting shaft 15 rotates to drive the transmission worm 16 to rotate, the transmission worm 16 rotates to drive the meshing transmission worm wheel 17 to rotate, and then can drive the rotating shaft 18 to rotate.

[0055] Preferably, a hydraulic push rod 5 is fixed to the inner side of the fixed shell 4, and a fixed plate 24 is fixed to the push rod of the hydraulic push rod 5. A lifting sleeve 25 is fixed to the bottom of the fixed plate 24. A connecting column 27 is slidably connected to the bottom of the lifting sleeve 25, so that the connecting column 27 can be lifted and lowered. A positioning threaded rod 26 is also fixed to the inside of the lifting sleeve 25. The outer side of the bottom end of the positioning threaded rod 26 is threadedly connected to the connecting column 27, so that the connecting column 27 can be replaced through the threaded connection. The bottom end of the connecting column 27 is bolted to a die-casting mold 28, so that the die-casting mold 28 can be easily replaced.

[0056] When the die-casting mold 28 needs to be replaced, the die-casting mold 28 can be rotated to drive the threaded connecting column 27 to rotate. The connecting column 27 rotates to lower the positioning threaded rod 26 connected through the thread, so that the connecting column 27 is separated from the positioning threaded rod 26, and then the bolts are rotated by corresponding tools to separate the connecting column 27 from the die-casting mold 28, so that the die-casting mold 28 can be replaced.

[0057] Furthermore, a positioning plate 29 is fixed to one end of the lifting sleeve 25, and a limiting mechanism for positioning the die-casting mold 28 is installed at the bottom of the positioning plate 29. The limiting mechanism includes a limiting shell 30, a lifting column 31 and a positioning block 34. The top of the limiting shell 30 is fixed to the positioning plate 29, and the lifting column 31 is slidably connected to the bottom of the limiting shell 30, so that the lifting column 31 can be lifted and slid. A pulling plate 33 is fixed to one end of the bottom of the lifting column 31, so that the lifting column 31 can be driven to rise by pulling the pulling plate 33. An elastic member is fixed to the top of the lifting column 31 and located inside the limiting shell 30. The elastic member is a reset spring 32 or a rubber block, so that the movement of the lifting column 31 can be reset by compression and rebound of the elastic member. A positioning block 34 is fixed to the bottom of the lifting column 31, and the positioning block 34 is slidably connected to the die-casting mold 28, so that when the positioning block 34 enters the interior of the die-casting mold 28 through the sliding connection, the die-casting mold 28 can be prevented from rotating.

[0058] When the die-casting mold 28 is being replaced, the pull plate 33 can be pulled so that the pull plate 33 drives the lifting column 31 to rise, and the lifting column 31 drives the positioning block 34 to rise, and the positioning block 34 is detached from the die-casting mold 28 through the sliding connection between the positioning block 34 and the die-casting mold 28. At the same time, the rising lifting column 31 squeezes the reset spring 32 under the limit of the limit shell 30. When the die-casting mold 28 is replaced, the pull plate 33 can be released, and then the rebound of the reset spring 32 allows the positioning block 34 to enter the replaced die-casting mold 28 through the sliding connection, thereby preventing the die-casting mold 28 from rotating by itself.

[0059] When the mold is working, first, when the shaping mold 6 needs to be replaced, the clamping drive motor 11 is electrically connected to the external power supply, and the clamping drive motor 11 is powered to drive the transmission gear 10 to rotate, and the transmission gear 10 rotates to drive the meshing transmission rack 9 to move, and the movement of the transmission rack 9 drives the connecting rod 8 to move, and the movement of the connecting rod 8 drives the clamping plate 7 to move, and the clamping plate 7 is connected to the fixed table 1 and the shaping mold 6 through a sliding connection, so that the clamping plate 7 is separated from the shaping mold 6 after moving, and the shaping mold 6 can be replaced;

[0060] When the height of the support column 2 needs to be adjusted and the rotating shaft 18 needs to be rotated, the lifting drive motor 12 is electrically connected to the external power supply so that the lifting drive motor 12 is energized and drives the first connecting gear 13 to rotate. The first connecting gear 13 rotates to drive the second connecting gear 14 to rotate. The second connecting gear 14 rotates to drive the connecting shaft 15 to rotate. The connecting shaft 15 rotates to drive the transmission worm 16 to rotate. The transmission worm 16 rotates to drive the meshing transmission worm gear 17 to rotate, thereby driving the rotating shaft 18 to rotate. The first bevel gears 20 on both sides are driven to rotate by the rotation of the rotating shaft 18. The first bevel gear 20 rotates to drive the second bevel gear 21 to rotate, so that the second bevel gears 21 on both sides rotate in the opposite direction. The rotation of the second bevel gear 21 drives the transmission shaft 22 to rotate. The transmission shaft 22 rotates to drive the rotation of the lifting threaded rod 23. The lifting threaded rod 23 on one side has an opposite thread rotation direction to the lifting threaded rod 23 on the other side. When the lifting threaded rod 23 rotates, it can simultaneously drive the threaded support column 2 to be lifted and lowered, thereby adjusting the height of the fixed shell 4.

[0061] When the die-casting mold 28 needs to be replaced, the die-casting mold 28 can be rotated to drive the threaded connection column 27 to rotate, and the connection column 27 rotates to lower the positioning threaded rod 26 connected by the thread, so that the connection column 27 is separated from the positioning threaded rod 26, and then the corresponding tool is used to rotate the bolt to separate the connection column 27 from the die-casting mold 28, so that the die-casting mold 28 can be replaced;

[0062] Then, the workpiece to be die-cast is placed on the top of the shaping mold 6 , and then the workpiece / die-casting to be processed is die-casted by the cooperation of the die-casting mold 28 and the shaping mold 6 .

[0063] The present invention also discloses a main body die casting forming mold forming process, comprising the following steps:

[0064] S101, placing the die-casting to be processed into the die-casting die hole 35 reserved on the shaping die 6;

[0065] S102, start the hydraulic push rod 5, drive the fixed plate 24 through the hydraulic push rod 5, and drive the die casting mold 28 through the connecting column 27, so that the die casting mold 28 extends into the die casting mold hole 35, and the die casting part located in the die casting mold hole 35 is die-casted;

[0066] S103, when the die casting is completed, the die casting mold 28 is withdrawn from the die casting mold hole 35;

[0067] S104, then driving the ejector rod 36 downward until the pull rod 40 is limited by the ejector plate 37, at which time the top of the ejector rod 36 is offset from the input hole 41, and air is blown toward the jack 42 through one end of the input hole 41 to assist in demoulding the die casting;

[0068] S105 , the ejector rod 36 is then driven upward again, so that the die casting is ejected through the ejector plate 37 , and demolding is achieved between the die and the molding die 6 .

[0069] Specifically, Figure 1 and Figure 8 As shown, the ejection mechanism includes an ejector rod 36 and an ejector plate 37, wherein the ejector plate 37 is located in an ejector plate groove 38 on the bottom wall of the die-casting mold hole 35, the upper end of the ejector rod 36 penetrates the top of the ejector plate 37 and is connected to the bottom of the ejector plate 37, the lower end of the ejector rod 36 extends outside the shaping mold 6, and is driven by the driving mechanism to eject the ejector plate 37 out of the ejector plate groove 38 or pull it back into the ejector plate groove 38. The ejector plate 37 is provided with a socket 42 for the ejector rod 36 to be inserted and a slot 43 for the pull rod 40 to be inserted, the ejector rod 36 is provided with a ring body 39, the pull rod 40 is connected to the ring body 39, and the socket 42 is provided with an input hole 41 near the top.

[0070] In the present invention, after the die-casting mold 28 extends into the die-casting mold hole 35 of the shaping mold 6, the die-casting mold 28 is matched to perform die-casting on the workpiece / die-casting to be processed. In this process, the push rod 36 is driven by a driving mechanism (such as an electric or hydraulic push rod), so that the top of the push rod 36 is flush with the top of the socket 42, that is, it is in contact with the bottom of the die-casting in the die-casting mold hole 35. At this time, the top of the L-shaped pull rod 40 is in contact with the top of the groove body 43. Due to the limitation of the groove body 43, the top of the push rod 36 is restricted and cannot move further upward, that is, it can only be moved to be flush with the top of the socket 42. In this way, it will not extend out of the top plate 37, thereby affecting the processing / die-casting of the die-casting by the die-casting mold 28. When the top of the push rod 36 is flush with the top of the socket 42, the input hole 41 will be blocked at this time. After the die-casting of the die-casting is completed, the push rod 36 is first pulled downward to make the pull rod 40 abut against the bottom of the groove body 43, so that the top of the push rod 36 will be offset from the input hole 41 and be located below the input hole 41, and then through an external air source (or other substances as required, such as coolant, etc.), the bottom of the die-casting can be blown. The gas enters from one end of the input hole 41, and then is used to blow toward the die-casting in the upper jack 42, and then blown out from the other end of the input hole 41, so as to achieve the purpose of rapid cooling, thereby making the demolding of the die-casting molding mold smoother and improving the quality of the molded die-casting.
