Description

Technical Field

[0001] The invention relates to the technical field of pipe casting, and in particular to a pipe connector casting device. Background Art

[0002] Pipe connectors are pipe system components used for connection, branching, diversion or sealing. Pipe connectors can be classified according to structure and material according to their functions and uses. Connectors are usually standard parts suitable for mass production by casting. During casting, it is necessary to pay attention to controlling the thickness of the parts to ensure that the parts can meet the required load. They can also be automated to speed up casting production. The casting devices of pipe connectors in the prior art are usually unable to achieve large-scale fully automatic continuous casting production of pipe connectors, and the degree of automation is low, which cannot meet the requirements of mass automatic production. Summary of the invention

[0003] In response to the above technical problems, the technical solution adopted by the present invention is: a pipe connector casting device, including a casting mechanism for casting, the casting mechanism including a base, the casting mechanism is provided with a cooling mechanism for cooling the cast pipe connector and a discharging mechanism for pouring out the pipe connector, the cooling mechanism includes a cleaning tank, the cleaning tank is fixedly mounted on the base, and the discharging mechanism includes a flip rack, which is fixedly mounted on the base.

[0004] Furthermore, the casting mechanism includes a top frame fixedly installed on the base, a center rotating column is rotatably installed on the base, the center rotating column is rotatably installed with the top frame, a center gear and a top cam are fixedly installed on the center rotating column, four extending columns are fixedly installed on the center rotating column, an inner groove column is rotatably installed in the extending column, a lower mold is fixedly installed on the inner groove column, a rotating mold gear is fixedly installed on the lower mold, a lifting frame is slidably installed on the extending column, an upper mold is fixedly installed on the lifting frame, a liquid inlet is provided on the upper mold, and a discharge slope is fixedly installed on the base.

[0005] Furthermore, four grooves are arranged on the inner groove column, four limit blocks are slidably installed in the extended column, a limit spring is arranged between the limit block and the extended column, and the limit block cooperates with the groove of the inner groove column.

[0006] Furthermore, a motor is fixedly mounted on the top frame, a toothless gear is fixedly mounted on the motor shaft of the motor, an intermittent wheel is rotatably mounted on the top frame, a transmission belt is wound around the intermittent wheel and the central gear, and the toothless gear is meshed with the intermittent wheel.

[0007] Furthermore, four grooves are arranged on the central rotating column, four central clamping blocks are slidably installed in the base, a clamping block spring is arranged between the central clamping block and the base, and the central clamping block cooperates with the grooves of the central rotating column.

[0008] Furthermore, a melting furnace is fixedly installed on the top frame. A feed hopper is fixedly installed on the melting furnace. A baffle plate is slidably installed in the feed hopper. A baffle spring is arranged between the baffle plate and the melting furnace. A partition plate is fixedly installed in the melting furnace.

[0009] Furthermore, a discharge block is slidably installed at the bottom of the melting furnace. A liquid outlet is arranged on the discharge block. A discharge spring is arranged between the discharge block and the melting furnace. In the initial state, the discharge port of the melting furnace is offset from the liquid outlet. When the discharge block is pushed open by the liquid inlet, the liquid inlet, the liquid outlet and the discharge port of the melting furnace are docked.

[0010] The motor drives the toothed gear to rotate, drives the intermittent wheel to rotate intermittently, drives the central gear, the central rotating column and the top cam to rotate intermittently through the transmission belt. Each time, the central rotating column and the top cam are driven to rotate by 90 degrees. When the central rotating column rotates, it will drive the lower die and the upper die to rotate together through four protruding columns. Whenever the central rotating column does not rotate, the central clamping block is inserted into the groove of the central rotating column, so that the central rotating column will not rotate under the action of external force. When the lower die moves below the melting furnace, the liquid inlet pushes the discharge block to slide outwards, and the discharge spring is stretched, so that the molten metal in the melting furnace enters between the lower die and the upper die through the liquid outlet and the liquid inlet to complete casting. When the central rotating column rotates next time, the liquid inlet leaves below the melting furnace, and the discharge spring rebounds, so that the discharge block closes the bottom of the melting furnace again. Through the intermittent rotation of the central rotating column, the pouring time each time is kept consistent. Metal blocks are placed on the baffle plate. Every time the top cam rotates four times, it will push the baffle plate to slide, so that the through-hole part of the baffle plate reaches below the feed hopper. At this time, the metal blocks on the baffle plate enter the melting furnace for heating and melting. The molten metal after melting drips to the bottom of the melting furnace through the partition plate. When the convex part of the top cam turns away, the baffle spring rebounds, so that the baffle plate closes the feed hopper again. At this time, the next batch of metal blocks can be placed on the baffle plate.

[0011] Furthermore, the cooling mechanism includes a cleaning pool filled with cooling water. A number of water pumps are fixedly installed on the cleaning pool. An upper water pipe is fixedly installed on the water pump. A lower water pipe is fixedly installed on the inner water pump. An upper spray head is fixedly installed on the upper water pipe. A lower spray head is fixedly installed on the lower water pipe.

[0012] When the central rotating column drives the lower die and the upper die after casting to reach between the upper spray head and the lower spray head, the water pump pumps water and sprays the water from the upper spray head and the lower spray head onto the lower die and the upper die to cool the lower die, the upper die and the pipe connectors therein.

[0013] Furthermore, the discharging mechanism includes a jacking arc block fixedly installed in the base. When the rotating die gear moves above the discharging slope, the rotating die gear meshes with the turning-over rack.

[0014] When the central rotating column drives the lower die and the upper die to reach the lifting arc block, the lifting arc block lifts the lifting frame, causing the lifting frame and the upper die to rise, separating the upper die from the lower die. The formed pipe connector is located in the lower die. Under the action of the turning-over rack, the lower die, the inner groove column and the turning die gear are driven to rotate 360 degrees. During the rotation process, the formed pipe connector is poured onto the discharging slope for discharging.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The casting mechanism, cooling mechanism and discharging mechanism provided by the present invention can realize intermittent feeding of raw materials for pipe connectors, intermittent discharging of molten metal, automatic casting, automatic cooling and automatic demoulding and discharging, with high automation degree and good continuity; (2) When the lower die and the upper die of the present invention move to the discharging mechanism, the upper die is lifted by the lifting arc block, and at the same time, the lower die is turned over by the turning-over rack, so that the metal block in the lower die can be smoothly poured out to realize discharging, and the discharging is convenient; (3) The top cam provided by the present invention will push the baffle to move once every four rotations, realizing that the metal block on the baffle falls into the melting furnace for automatic feeding. And the molten metal after melting will be stored in the melting furnace. After the upper die reaches below it, automatic casting will be carried out. And because the intermittent rotation time of the central rotating column is fixed, the casting amount is kept constant and the casting accuracy is high. Description of the Drawings

[0026] As Figures 2-5 shown, the casting mechanism includes a top frame 103 fixedly installed on the base 101. A central rotating column 108 is rotatably installed on the base 101. The central rotating column 108 is rotatably installed with the top frame 103. A central gear 109 and a top cam 110 are fixedly installed on the central rotating column 108. Four protruding columns 111 are fixedly installed on the central rotating column 108. An inner groove column 113 is rotatably installed in the protruding column 111. A lower mold 112 is fixedly installed on the inner groove column 113. A mold rotating gear 116 is fixedly installed on the lower mold 112. A lifting frame 121 is slidably installed on the protruding column 111. An upper mold 114 is fixedly installed on the lifting frame 121. A liquid inlet 115 is provided on the upper mold 114. A discharge slope 102 is fixedly installed on the base 101.

[0027] As Figures 2-5 shown, four grooves are provided on the inner groove column 113. Four limit clamping blocks 119 are slidably installed in the protruding column 111. A limit spring 120 is provided between the limit clamping block 119 and the protruding column 111. The limit clamping block 119 cooperates with the groove of the inner groove column 113.

[0028] As shown Figures 2-5 in Figure [not provided], a motor 104 is fixedly installed on the top frame 103. A toothless gear 105 is fixedly installed on the motor shaft of the motor 104. An intermittent wheel 106 is rotatably installed on the top frame 103. A transmission belt 107 is wound around the intermittent wheel 106 and the central gear 109. The toothless gear 105 meshes with the intermittent wheel 106.

[0029] As shown Figures 2-5 in Figure [not provided], four grooves are provided on the central rotating column 108. Four central clamping blocks 117 are slidably installed in the base 101. A clamping block spring 118 is provided between the central clamping block 117 and the base 101. The central clamping block 117 cooperates with the grooves of the central rotating column 108.

[0030] As shown Figures 2-5 in Figure [not provided], a melting furnace 124 is fixedly installed on the top frame 103. A feed hopper 122 is fixedly installed on the melting furnace 124. A baffle plate 123 is slidably installed in the feed hopper 122. A baffle spring 125 is provided between the baffle plate 123 and the melting furnace 124. A partition plate 126 is fixedly installed in the melting furnace 124.

[0031] As shown Figures 2-5 in Figure [not provided], a discharge block 127 is slidably installed at the bottom of the melting furnace 124. A liquid outlet 129 is provided on the discharge block 127. A discharge spring 128 is provided between the discharge block 127 and the melting furnace 124. In the initial state, the discharge port of the melting furnace 124 is offset from the liquid outlet 129. When the discharge block 127 is pushed open by the liquid inlet 115, the liquid inlet 115, the liquid outlet 129 and the discharge port of the melting furnace 124 are docked.

[0032] The motor 104 drives the toothless gear 105 to rotate, driving the intermittent wheel 106 to rotate intermittently. Through the transmission belt 107, it drives the central gear 109, the central rotating column 108, and the top cam 110 to rotate intermittently. Each time, the central rotating column 108 and the top cam 110 are driven to rotate by ninety degrees. The rotation of the central rotating column 108 will drive the lower die 112 and the upper die 114 to rotate together through four protruding columns 111. Whenever the central rotating column 108 does not rotate, the central latch 117 is inserted into the groove of the central rotating column 108, preventing the central rotating column 108 from rotating under external force. When the lower die 112 moves below the melting furnace 124, the liquid inlet 115 pushes the discharge block 127 to slide outwards, stretching the discharge spring 128. Then, the molten metal in the melting furnace 124 enters between the lower die 112 and the upper die 114 through the liquid outlet 129 and the liquid inlet 115, completing the casting. When the central rotating column 108 rotates next time, the liquid inlet 115 moves away from below the melting furnace 124, and the discharge spring 128 rebounds, causing the discharge block 127 to seal the area below the melting furnace 124 again. Through the intermittent rotation of the central rotating column 108, the pouring time for each time is kept consistent. There are metal blocks placed on the baffle 123. Every time the top cam 110 rotates four times, it pushes the baffle 123 to slide, making the through-hole part of the baffle 123 reach below the feed hopper 122. At this time, the metal blocks on the baffle 123 enter the melting furnace 124 for heating and melting. The molten metal after melting drips onto the bottom of the melting furnace 124 through the partition 126. When the protruding part of the top cam 110 turns away, the baffle spring 125 rebounds, causing the baffle 123 to seal the feed hopper 122 again. At this time, the next batch of metal blocks can be placed on the baffle 123.

[0033] As Figure 6 shown, the cooling mechanism includes a cleaning pool 201 filled with cooling water. A number of water pumps 202 are fixedly installed on the cleaning pool 201. An upper water pipe 203 is fixedly installed on the water pump 202. A lower water pipe 205 is fixedly installed on the inner water pump 202. An upper spray head 204 is fixedly installed on the upper water pipe 203. A lower spray head 206 is fixedly installed on the lower water pipe 205.

[0034] When the central rotating column 108 drives the cast lower die 112 and upper die 114 to reach between the upper spray head 204 and the lower spray head 206, the water pump 202 pumps water, spraying water from the upper spray head 204 and the lower spray head 206 onto the lower die 112 and the upper die 114 to cool the lower die 112, the upper die 114, and the pipe connectors inside them.

[0035] As Figure 7 shown, the discharging mechanism includes a jacking arc block 302 fixedly installed in the base 101. When the rotating die gear 116 moves above the discharging slope 102, the rotating die gear 116 meshes with the turning face rack 301.

[0036] When the central rotating column 108 drives the lower die 112 and the upper die 114 to reach the jacking arc block 302, the jacking arc block 302 jacks up the lifting frame 121, causing the lifting frame 121 and the upper die 114 to rise, separating the upper die 114 from the lower die 112. The formed pipe connector is located in the lower die 112. Under the action of the turning rack 301, the lower die 112, the inner groove column 113 and the turning die gear 116 are driven to rotate 360 degrees. During the rotation, the formed pipe connector is poured onto the discharge slope 102 for discharging.

[0037] The working principle of a pipe fitting casting device disclosed by the present invention is as follows: The motor 104 drives the toothless gear 105 to rotate, driving the intermittent wheel 106 to rotate intermittently. Through the transmission belt 107, the central gear 109, the central rotating column 108, and the top cam 110 are driven to rotate intermittently. Each time, the central rotating column 108 and the top cam 110 are driven to rotate by 90 degrees. When the central rotating column 108 rotates, it will drive the lower mold 112 and the upper mold 114 to rotate together through four protruding columns 111. Whenever the central rotating column 108 does not rotate, the central block 117 is inserted into the groove of the central rotating column 108, so that the central rotating column 108 will not rotate under the action of external force. When the lower mold 112 moves below the melting furnace 124, the liquid inlet 115 pushes the discharging block 127 to slide outwards, and the discharging spring 128 is stretched. Then, the molten metal in the melting furnace 124 enters between the lower mold 112 and the upper mold 114 through the liquid outlet 129 and the liquid inlet 115 to complete the casting. When the central rotating column 108 rotates next time, the liquid inlet 115 leaves below the melting furnace 124, and the discharging spring 128 rebounds, so that the discharging block 127 closes the lower part of the melting furnace 124 again. Through the intermittent rotation of the central rotating column 108, the pouring time for each time is kept consistent. Metal blocks are placed on the baffle plate 123. Every time the top cam 110 rotates four times, it will push the baffle plate 123 to slide, so that the through-hole part of the baffle plate 123 reaches below the feed hopper 122. At this time, the metal blocks on the baffle plate 123 enter the melting furnace 124 for heating and melting. The molten metal after melting drips to the bottom of the melting furnace 124 through the partition plate 126. When the convex part of the top cam 110 turns away, the baffle spring 125 rebounds, so that the baffle plate 123 closes the feed hopper 122 again. At this time, the next batch of metal blocks can be placed on the baffle plate 123. When the central rotating column 108 drives the lower mold 112 and the upper mold 114 that have completed casting to reach between the upper spray head 204 and the lower spray head 206, the water pump 202 pumps water, and the water is sprayed out from the upper spray head 204 and the lower spray head 206 onto the lower mold 112 and the upper mold 114 to cool the lower mold 112, the upper mold 114, and the pipe fittings therein. When the central rotating column 108 drives the lower mold 112 and the upper mold 114 to reach the jacking arc block 302, the jacking arc block 302 jacks up the lifting frame 121, so that the lifting frame 121 and the upper mold 114 rise, separating the upper mold 114 from the lower mold 112. The formed pipe fittings are located in the lower mold 112. Under the action of the turning-over rack 301, the lower mold 112, the inner groove column 113, and the rotating mold gear 116 are driven to rotate 360 degrees. During the rotation, the formed pipe fittings are poured onto the discharging slope 102 for discharging.
