[0006] As a further solution of the present invention, two limiting columns are fixed to the inner wall of the fixing frame, and the limiting columns penetrate through the two mold bases. The four limiting columns are respectively located at the four corners of one side of the mold base.

[0007] As a further solution of the present invention, the adjustment assembly includes a mounting frame, which is fixed to the top of the fixing frame, and a bidirectional electric hydraulic rod is installed at the bottom of the mounting frame, and both ends of the bidirectional electric hydraulic rod are fixed to two mold bases.

[0008] As a further solution of the present invention, the knocking assembly includes a connecting plate, and sliding rods slide through the four corners of the connecting plate respectively. A spring is connected to the outer sleeve of the sliding rod, one end of the spring is fixed to one side of the mold base, and the other end of the spring is fixed to the connecting plate.

[0009] As a further solution of the present invention, a plurality of knocking bars are fixed to one side of the connecting plate close to the mold base. The knocking bars are T-shaped and overlap the mold base. A plurality of through holes are formed on the knocking bars. The knocking bars are metal heat conducting plates.

[0010] As a further solution of the present invention, the deflection assembly includes a connecting shaft, bearing seats are respectively installed on both sides outside the connecting shaft, the bearing seats are fixed on one side of the mold base, a plurality of cams are clamped in the middle of the connecting shaft, the cams are located in the baffle cover, and gears are respectively fixedly connected to the two ends of the connecting shaft, and the gears are meshed with teeth.

[0011] As a further solution of the present invention, a drop hole is provided above the feeding assembly, and the drop hole is opened in the middle of the base. The feeding assembly includes two transmission rollers, and the transmission rollers are installed between two support frames, and the outer shells of the two transmission rollers are connected with the same transmission steel belt, and the outer walls of the transmission steel belt are respectively provided with baffle bars, and a motor is installed at one end of one of the transmission rollers, and the motor is fixed on the outside of the support frame.

[0012] A method for using a demoulding device for a metal casting mold that is convenient to transport, the method comprising the following steps: When demolding the metal casting mold, the two-way electric hydraulic rods on both sides of the mold base are controlled to work. The two-way electric hydraulic rods are extended to drive the two mold bases to move away from each other, so that the mold base can slide outside the limit column. The limit column supports and limits the mold base, thereby improving the movement stability of the mold base. During the movement of the mold base, the knocking assembly, the baffle and the deflection assembly can be driven to move synchronously. Because the gear at the end of the deflection assembly is meshed and connected with the teeth on the partition, the gear can rotate during the movement, and the gear drives multiple cams to rotate through the connecting shaft. During the rotation of the cam, the protruding end thereof can squeeze the baffle, so that the baffle pulls the connecting plate to move outside the sliding rod, and the connecting plate drives multiple knocking bars to separate from the mold base; When the protruding end of the cam is separated from the blocking cover, the tension of multiple springs can drive the connecting plate to approach the die base, and the connecting plate drives multiple knocking bars to contact the die base. Under the tension of the springs, the knocking bars can quickly return to their positions and knock on the die base, causing the die base to vibrate. As the cam continues to rotate, the connecting plate will drive multiple knocking bars to continuously knock on the die base, thereby shaking off the casting in the die base, achieving the purpose of automatic demoulding. After the casting is separated from the die base, it will fall into the feeding assembly through the drop hole; Control the feeding assembly to make the motor drive one of the transmission rollers to rotate, and the transmission roller drives the transmission steel belt to work. Since the casting falls on the transmission steel belt, the transmission steel belt can realize the purpose of automatic conveying of the casting. After the feeding is completed, the motor is controlled to stop working and the next casting work is carried out; By controlling the operation of the bidirectional electric hydraulic rod in the fixed frame, the bidirectional electric hydraulic rod is contracted and the two mold bases are pulled closer to each other. The mold base slides outside the limit column, and the mold base is limited by the limit column to improve the stability of the horizontal movement of the mold base and ensure the mold clamping accuracy. During the movement of the mold base, the connecting shaft and the gear are driven to move through the bearing seat. Because the gear is engaged with the teeth, the gear drives the cam to rotate through the connecting shaft. Similarly, the rotation of the cam can enable the connecting plate to drive the knocking bar to knock the mold base, which can shake off the residual material attached to the mold cavity in the mold base. After the opposite surfaces of the two mold bases contact, the protruding end of the cam is separated from the baffle, and the baffle and the connecting plate are no longer subjected to force. The knocking bar is tightly attached to the mold base through the tension of the spring. Because the knocking bar is a metal heat-conducting plate, the heat on the mold base can be transferred to multiple knocking bars. With the setting of the through holes on the knocking bar, the heat conduction area is expanded to improve the heat dissipation effect of the mold base. The two mold bases are combined into a complete metal casting mold, and the pouring holes on the metal casting mold are used for the injection of molten metal.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention drives the two mold bases to move away from each other by extending the bidirectional electric hydraulic rod. During the movement of the mold base, the knocking assembly, the baffle cover and the deflection assembly can be driven to move synchronously. The gear will mesh with the teeth during the movement, so that the gear drives multiple cams to rotate through the connecting shaft. During the rotation of the cam, the protruding end of the cam can squeeze the baffle cover, so that the baffle cover pulls the connecting plate to move outside the sliding rod, and the connecting plate drives the multiple knocking bars to separate from the mold base. When the protruding end of the cam separates from the baffle cover, the connecting plate can be driven to When the mold base approaches, the connecting plate drives multiple knocking bars to contact the mold base. Under the tension of the spring, the knocking bars can quickly return to their positions and knock on the mold base, causing the mold base to vibrate. As the cam continues to rotate, the connecting plate drives multiple knocking bars to continuously knock on the mold base, thereby shaking off the casting in the mold base and achieving the purpose of automatic demolding. In the process of the knocking bars knocking on the mold base, the vibration generated is transmitted to the entire mold cavity in the mold base, so that the casting in the mold cavity is evenly stressed, which is not easy to cause deformation or wear to the casting, thereby ensuring the quality of the casting product.

[0014] 2. The present invention uses a bidirectional electric hydraulic rod to open two mold bases. After the casting is separated from the mold base, it will fall into the feeding assembly through the drop hole. To control the feeding assembly to work, the motor can drive one of the transmission rollers to rotate, and the transmission roller drives the transmission steel belt to work. Because the casting falls on the transmission steel belt, the transmission steel belt can achieve the purpose of automatic transportation of the casting, thereby facilitating the efficient transportation of the casting, without the need to lift the material and transport it, thereby improving the convenience of operation. During the contraction of the bidirectional electric hydraulic rod, the rotation of the cam can enable the connecting plate to drive the knocking bar to knock the mold base, which can shake off the residual material attached to the mold cavity in the mold base, thereby preventing the residue in the mold cavity from affecting the next casting accuracy. After the two mold bases are released, the knocking bar is tightly attached to the mold base through the tension of the spring. Because the knocking bar is a metal heat-conducting plate, the heat on the mold base can be transferred to multiple knocking bars. Combined with the setting of the through holes on the knocking bar, the heat conduction area is expanded, thereby improving the heat dissipation effect of the mold base.

[0026] A method for using a demoulding device for a metal casting mold that is convenient to transport, the method comprising the following steps: When demolding the metal casting mold, the two-way electric hydraulic rod 702 on both sides of the mold base 3 is controlled to work. The two-way electric hydraulic rod 702 is extended to drive the two mold bases 3 to move away from each other, so that the mold base 3 can slide outside the limit column 6. The limit column 6 supports and limits the mold base 3, improves the movement stability of the mold base 3, and can drive the knocking assembly 8, the baffle 9 and the deflection assembly 10 to move synchronously during the movement of the mold base 3. Because the gear 104 at the end of the deflection assembly 10 is meshed and connected with the teeth 12 on the partition 11, the gear 104 can rotate during the movement, and the gear 104 drives the multiple cams 103 to rotate through the connecting shaft 101. During the rotation of the cam 103, its protruding end can squeeze the baffle 9, so that the baffle 9 pulls the connecting plate 801 to move outside the sliding rod 802, and the connecting plate 801 drives the multiple knocking bars 804 to separate from the mold base 3; When the protruding end of the cam 103 is separated from the blocking cover 9, the tension of the multiple springs 803 can drive the connecting plate 801 to approach the mold base 3, and the connecting plate 801 drives the multiple knocking bars 804 to contact the mold base 3. Under the tension of the springs 803, the knocking bars 804 can quickly return to their positions and knock on the mold base 3, causing the mold base 3 to vibrate. As the cam 103 continues to rotate, the connecting plate 801 will drive the multiple knocking bars 804 to continuously knock on the mold base 3, thereby shaking off the casting in the mold base 3, achieving the purpose of automatic demoulding. After the casting is separated from the mold base 3, it will fall into the feeding assembly 13 through the drop hole 4; The feeding assembly 13 is controlled to work, so that the motor 134 can drive one of the transmission rollers 131 to rotate, and the transmission roller 131 drives the transmission steel belt 132 to work. Since the casting falls on the transmission steel belt 132, the transmission steel belt 132 can realize the purpose of automatic conveying of the casting. After the feeding is completed, the motor 134 is controlled to stop working and the next casting work is carried out; By controlling the operation of the bidirectional electric hydraulic rod 702 in the fixed frame 5, the bidirectional electric hydraulic rod 702 is contracted and the two mold bases 3 are pulled closer to each other. The mold base 3 slides outside the limiting column 6, and the mold base 3 is limited by the limiting column 6 to improve the horizontal movement stability of the mold base 3 and ensure the mold clamping accuracy. During the movement of the mold base 3, the connecting shaft 101 and the gear 104 are driven to move through the bearing seat 102. Because the gear 104 is engaged with the teeth 12, the gear 104 drives the cam 103 to rotate through the connecting shaft 101. Similarly, the rotation of the cam 103 can enable the connecting plate 801 to drive the knocking bar 804 to knock the mold base 3 , which can shake off the residual materials attached to the mold cavity in the mold base 3. After the opposite surfaces of the two mold bases 3 come into contact, the protruding end of the cam 103 is separated from the baffle 9, and the baffle 9 and the connecting plate 801 are no longer subjected to force. Through the pulling force of the spring 803, the knocking bar 804 is tightly attached to the mold base 3. Because the knocking bar 804 is a metal heat-conducting plate, the heat on the mold base 3 can be transferred to multiple knocking bars 804. With the setting of the through holes 805 on the knocking bars 804, the heat conduction area is expanded and the heat dissipation effect of the mold base 3 is improved. The two mold bases 3 are combined into a complete metal casting mold, and the pouring holes on the metal casting mold are used for injecting molten metal.

During the movement of the mold base (3), the bearing seat (102) drives the connecting shaft (101) and the gear (104) to move. Since the gear (104) is meshed with the teeth (12), the gear (104) drives the cam (103) to rotate through the connecting shaft (101). Similarly, the rotation of the cam (103) can cause the connecting plate (801) to drive the knocking bar (804) to knock. The striking mold base (3) can shake off the residual material attached to the mold cavity of the mold base (3). After the opposite surfaces of the two mold bases (3) come into contact, the protruding end of the cam (103) is separated from the blocking cover (9), and the blocking cover (9) and the connecting plate (801) are no longer subjected to force. Through the pulling force of the spring (803), the striking bar (804) and the mold base (3) are tightly attached. Because the striking bar (804) is a metal heat conducting plate, the heat on the mold base (3) can be transferred to the multiple striking bars (804). With the arrangement of the through holes (805) on the striking bars (804), the heat conduction area is expanded, thereby improving the heat dissipation effect of the mold base (3). The two mold bases (3) are combined into a complete metal casting mold, and the pouring holes on the metal casting mold are used for injecting metal melt.
