An auxiliary motor 144 is fixedly mounted on the auxiliary support seat 110, and the output shaft of the auxiliary motor 144 is fixedly connected to the auxiliary gear 143.

[0040] An arc-shaped groove is provided on the arc-shaped rack 145, and a transmission short rod 152 is fixedly provided on the side of the arc-shaped friction plate 146.

An auxiliary push rod 147 is fixedly provided on the upper end of the arc-shaped rack 145, and an auxiliary rotating plate 148 is rotatably installed on the arc-shaped friction plate 146. One end of the auxiliary rotating plate 148 contacts the auxiliary pressing plate 149, and the other end of the auxiliary rotating plate 148 contacts the auxiliary push rod 147.

[0041] The switching motor 112 is started to drive the switching turret 102 to rotate, so that one of the two switching round seats 103 moves to the bottom of the pouring funnel 105, and the limit block 128 on the fan-shaped adjustment plate 126 disengages from the contact with the fan-shaped limit strip 106, and the limit strip 127 on the fan-shaped adjustment plate 126 moves to the position between the two limit blocks 2 142. The auxiliary gear ring 125 on the fan-shaped adjustment plate 126 is meshed with the adjustment gear 151 to form a gear pair, and then the auxiliary motor 144 is started to drive the auxiliary gear 143 to rotate and then drive the arc rack 145 to move upward. Under the action of the friction force between the arc friction plate 146 and the auxiliary support seat 110, the transmission short rod 152 moves on the arc groove on the arc rack 145, that is, the arc rack 145 moves upward relative to the arc friction plate 146, and the auxiliary push rod 147 moves upward synchronously, that is, the auxiliary rotating plate 148 rotates, which in turn causes the auxiliary pressing plate 149 to move downward, the spring between the auxiliary pressing plate 149 and the arc friction plate 146 is compressed, the auxiliary ring plate 140 and the annular support plate 139 move downward synchronously, the limiting long rod 141 and the slot on the auxiliary gear ring 125 that cooperates with the limiting long rod 141 are engaged, and the lower end of the pouring funnel 105 is engaged with the pouring hole on the upper mold 107. At this time, the transmission short rod 152 moves to the lowest end of the arc slide groove of the arc rack 145, and the auxiliary gear 143 continues to rotate. Under the action of the transmission short rod 152, the arc rack 145 and the arc friction plate 146 rotate synchronously, and under the action of the limiting strip plate 127 and the two limiting blocks 142, the fan-shaped adjustment plate 126 rotates, that is, the upper mold 107 and the lower mold 108 are tilted.

[0042] By injecting pouring liquid into the auxiliary funnel 104, the pouring liquid enters the pouring funnel 105 along the auxiliary funnel 104, and then pours into the cavity between the upper mold 107 and the lower mold 108 through the pouring hole of the upper mold 107. At the same time of pouring, the positioning motor 150 is started to drive the positioning gear 151 to rotate, that is, the auxiliary gear ring 125 rotates, and then the upper mold 107 and the lower mold 108 rotate. Under the action of the limiting long rod 141, the auxiliary ring plate 140 rotates on the annular support plate 139 , the pouring funnel 105 rotates synchronously, and then the auxiliary motor 144 is started to drive the auxiliary gear 143 to rotate, so that the upper mold 107 and the lower mold 108 are tilted. Under the action of the positioning gear 151, the tilt position of the upper mold 107 and the lower mold 108 continues to change, and the lower end of the auxiliary funnel 104 is always on the inner side of the pouring funnel 105, so that the upper mold 107 and the lower mold 108 are tilted and rotated during pouring, thereby ensuring that the internal cavity can be fully filled, thereby ensuring the quality of the product after pouring.

[0043] A transfer assembly is provided on the base 101, and the transfer assembly includes a transfer base 120, an L-shaped slide 123 is symmetrically slidably installed on the transfer base 120, a fan-shaped rotating plate 109 is rotatably installed on the base 101, a transfer motor 114 is fixedly installed on the base 101, the output shaft of the transfer motor 114 is fixedly connected to the fan-shaped rotating plate 109, a trapezoidal push plate 117 and a transfer strip plate 118 are fixedly provided on the fan-shaped rotating plate 109, an arc-shaped rotating plate 116 is rotatably installed on the fan-shaped rotating plate 109, and a splitting motor 115 is fixedly installed on the fan-shaped rotating plate 109. The arc-shaped rotating plate 116 is fixedly connected to the output shaft of the splitting motor 115, and the transmission round block 133 is provided with an arc-shaped sliding groove that cooperates with the arc-shaped rotating plate 116. The transfer electric cylinder 119 is fixedly installed on the transfer strip 118, and the transfer base 120 is fixedly installed on the piston rod end of the transfer electric cylinder 119. A bidirectional screw rod 121 is rotatably installed on the transfer base 120, and the L-shaped slide 123 forms a spiral pair with the bidirectional screw rod 121. A clamping motor 122 is fixedly installed on the transfer base 120, and the output shaft of the clamping motor 122 is fixedly connected to the bidirectional screw rod 121.

[0044] In the initial position, the split motor 115 is located at the farthest position from the switching rotary frame 102, that is, the fan-shaped rotating plate 109 is located outside the switching rotary frame 102, and a conveyor belt is provided below the L-shaped slide 123 in this position.

[0045] After the upper mold 107 and the lower mold 108 are finished pouring, the switching turret 102 is driven to rotate 180 degrees, so that the upper mold 107 and the lower mold 108 move to the position farthest from the auxiliary support seat 110, and then the transfer motor 114 is started to drive the fan-shaped rotating plate 109 to rotate 180 degrees, and the arc rotating plate 116 and the trapezoidal push plate 117 move to the bottom of the lower mold 108, and the arc sliding groove on the arc rotating plate 116 and the transmission round block 133 corresponding to the lower mold 108 are engaged. Under the action of the trapezoidal push plate 117, the pressing ring plate 130 corresponding to the lower mold 108 moves upward, and the spring between the pressing ring plate 130 and the supporting strip plate 134 is compressed, and the inner ratchet ring 131 is pressed. The movement occurs synchronously, the inner ratchet ring 131 disengages and engages with the outer ratchet 132. Under the dead weight of the upper mold 107 and the lower mold 108, the auxiliary gear ring 125 will not rotate relative to the fan-shaped adjustment plate 126. Then the splitting motor 115 is started to drive the arc-shaped rotating plate 116 to rotate, and the outer ratchet 132 disengages from the contact with the inner ratchet ring 131. The outer ratchet 132 can rotate freely, that is, the transmission block 133 rotates under the action of the arc-shaped rotating plate 116, and then the splitting gear 129 rotates, that is, the driven gear 138 rotates, and the two fan-shaped limit rotating plates 137 rotate synchronously, and finally the fan-shaped limit rotating plate 137 is disengaged from the contact with the lower mold 108.

[0046] At this time, the transfer base 120 is located just above the upper mold 107. The transfer electric cylinder 119 is started to drive the transfer base 120 to move downward, so that the lower end of the L-shaped slide 123 moves to the bottom of the lower mold 108. The clamping motor 122 is then started to drive the bidirectional screw rod 121 to rotate, so that the two L-shaped slides 123 move in the direction close to the axis of the transfer electric cylinder 119, and finally the L-shaped slide 123 contacts the side of the lower mold 108. The transfer electric cylinder 119 is then started to drive the transfer base 120 to move upward. Under the action of the L-shaped slide 123, the upper mold 107 and the lower mold 108 move upward synchronously, and then the fan-shaped rotating plate 109 is driven to rotate 180 degrees, so that the upper mold 107 and the lower mold 108 are moved upward synchronously. 7 and the lower mold 108 are rotated 180 degrees, and the upper mold 107 and the lower mold 108 are placed on the conveyor belt below for transportation, so as to facilitate the subsequent demoulding of the upper mold 107 and the lower mold 108, and then the uncast upper mold 107 and the lower mold 108 are moved to the bottom of the transfer base 120 by the conveyor belt, and then the new upper mold 107 and the lower mold 108 are placed on the supporting base 135 by the L-shaped slide 123. The upper mold 107 and the lower mold 108 are always in a fixed state under the action of the bolts 124. After the casting is completed and they are transported to the next demoulding process by the conveyor belt, the upper mold 107 and the lower mold 108 are separated by the bolts 124.

[0047] Working principle: Start the switching motor 112 to drive the switching rotating frame 102 to rotate, so that the uncast upper mold 107 and the lower mold 108 move to the right below the casting funnel 105, and the cast upper mold 107 and the lower mold 108 move to the position farthest from the auxiliary support seat 110, and then start the auxiliary motor 144 to drive the arc rack 145 to rotate, and the transmission short rod 152 moves in the arc chute on the arc rack 145, so that the lower end of the casting funnel 105 is engaged with the casting hole on the upper mold 107, and the limiting long rod 141 is engaged with the slot on the auxiliary gear ring 125, and then the casting funnel 104 and the casting funnel 105 are upwardly Pouring is carried out in the cavity between the mold 107 and the lower mold 108, and then the positioning motor 150 is started to drive the auxiliary gear ring 125 to rotate, and continue to drive the auxiliary gear 143 to rotate, so that the arc rack 145 and the arc friction plate 146 move synchronously, and under the action of the limit block 2 142 and the limit strip 127, the upper mold 107 and the lower mold 108 are in a tilted state, that is, the upper mold 107 and the lower mold 108 are rotated in a tilted state, so that the chambers inside the upper mold 107 and the lower mold 108 can be fully filled during pouring, thereby avoiding bubbles and cavities inside the upper mold 107 and the lower mold 108.

[0048] While the upper mold 107 and the lower mold 108 are being poured, the transfer motor 114, the splitting motor 115, the transfer electric cylinder 119, and the clamping motor 122 are started so that the upper mold 107 and the lower mold 108 farthest from the auxiliary support seat 110 are removed and transported to the next process, that is, the upper mold 107 and the lower mold 108 after pouring are transported to the next process, and the new upper mold 107 and the lower mold 108 are placed on the support base 135.

[0049] Repeat the above steps to achieve continuous pouring.

[0050] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
