The liquid storage cylinder 501 is fixedly arranged at one end of the fixed cylinder frame 301, and the main piston 502 is slidably assembled inside the liquid storage cylinder 501. The traction disk 503 is arranged at one end of the liquid storage cylinder 501 and is assembled and connected with the main piston 502. One end of the liquid storage cylinder 501 is also connected with a front suction pipe 504 and a front discharge pipe 505, and the front suction pipe 504 and the front discharge pipe 505 are connected to the injection mold 202.

[0029] When this embodiment is actually used, during the process of automated production of the two-color injection molding machine, the mold frame 201 is fixedly rotated and assembled on the base 101, and one end of the mold frame 201 is fixedly connected to two groups of injection molds 202. The two-color injection molding machine has three working processes. The first working process includes the two groups of injection molds 202 performing injection molding operations at the same time, the second working process includes the two groups of injection molds 202 opening the molds at the same time and the mold frame 201 rotating 180° on the fixed axis, and the third working process includes the two groups of injection molds 202 closing the molds again. During the first working process, the two groups of injection molds 202 are in a heating state. Before the molds are opened, the cooling water in the cooling pipe in the mold continuously absorbs heat and heats up. At this time, by controlling the positive and negative pressure states inside the liquid storage cylinder 501, the high-temperature water pumps in the two groups of molds can be sucked into the liquid storage cylinder 501 for temporary storage. When the two groups of injection molds 202 are in the mold opening state, the high-temperature water pumps in the two groups of molds can be sucked into the liquid storage cylinder 501 for temporary storage. Before the state, the guide component 4 continuously outputs cooling water to the two groups of injection molds 202 through the connected external pipeline to quickly cool down the molds. During the second working process, the mold frame 201 rotates 180° and the two groups of molds are swapped. At this time, the sliding sleeve 303 arranged in the locking sleeve 302 slides out, and the two groups of molds are simultaneously jetted and cooled by the pressurized air source to accelerate the cooling of the parts in the molds. During the third working process, after the two groups of injection molds 202 are closed, the high-temperature water stored in the inner cavity of the liquid storage cylinder 501 is pumped into the two groups of injection molds 202 again through the pipeline, and the cooling water in the cooling pipe of the injection mold 202 is discharged, so that the high-temperature water with residual heat can preheat the mold, so that the injection mold 202 can quickly reach the mold temperature required for injection molding, thereby improving the efficiency of the injection molding operation, effectively utilizing the residual heat value, and achieving the purpose of energy conservation and emission reduction.

[0030] See also Figure 3 In a preferred embodiment of the present invention, the fixed frame assembly 3 also includes a sliding rod 307, a convex groove section 308 and a groove section 309. The sliding rod 307 is fixedly arranged at one end of the side ear piece 306. The outer diameter end of the locking sleeve 302 is also provided with a convex groove section 308 and a groove section 309. The sliding rod 307 slides against the convex groove section 308 and the groove section 309.

[0031] In actual application of this embodiment, the sliding bar member 307 is fixedly arranged on one side of the side ear member 306. When the mold frame 201 is rotating, since the guide rod 305 is fixedly arranged on one side of the mold frame 201, the guide rod 305 synchronously pulls the side ear member 306 to rotate in the yoz plane. During the rotation of the side ear member 306, since the sliding bar member 307 elastically slides against the convex groove section 308 and the groove section 309, when the sliding bar member 307 moves from the groove section 309 to the side of the convex groove section 308, the sliding sleeve 303 synchronously moves along the positive direction of the first direction x, so that when the sliding sleeve 303 slides to the extreme position, the two groups of injection holes 304 on the end side are respectively aligned toward the two groups of injection molds 202, so that the ejected gas directly acts on the parts of the mold.

[0032] See also Figure 6 In a preferred embodiment of the present invention, the fixed frame assembly 3 also includes a hole seat 310, an air guide rod 311, an air guide hole 312 and an elastic sealing head 313.

[0033] In actual application of this embodiment, the hole seat 310 is arranged at the end of the sliding sleeve 303, the air guide rod 311 is fixedly arranged in the locking sleeve 302, and the air guide hole 312 is also arranged on the air guide rod 311, so that the internal cavity of the air guide rod 311 is connected with the internal cavity of the locking sleeve 302 through the air guide hole 312, and when the sliding sleeve 303 moves in the positive direction of the first direction x, the hole seat 310 on the end side of the sliding sleeve 303 slides and abuts against the elastic plugging head 313, the elastic sealing head 313 overcomes the elastic force and moves in the positive direction of the first direction x, so that the air hole arranged at the end of the air guide rod 311 and close to the elastic sealing head 313 is opened, so that the inner cavity of the locking sleeve 302 is connected with the inner cavity of the sliding sleeve 303. At this time, the high-pressure gas in the locking sleeve 302 can be output to the sliding sleeve 303 through the air guide rod 311, and then sprayed onto the parts on the mold side through the injection hole 304 at the end of the sliding sleeve 303.

[0034] See also Figure 7In a preferred embodiment of the present embodiment, the automatic production equipment of the two-color injection molding machine further includes a guide assembly 4, the guide assembly 4 includes a front guide ring 401, a rear guide ring 402, a first cavity 403, a second cavity 404, a front mold cooling pipe 405 and a rear mold cooling pipe 406, the front guide ring 401 is fixedly arranged at one end of the mold frame 201, the rear guide ring 402 is fixedly arranged at one end of the fixed cylinder frame 301, and the rear guide ring 402 is rotatably sleeved on the front guide ring 401, the front guide ring 401 and the rear guide ring 4 02, an independent first cavity 403 and a second cavity 404 are arranged between the front suction pipe 504 and the second cavity 404, the front exhaust pipe 505 is connected to the first cavity 403, one end of the front mold cooling pipe 405 and the rear mold cooling pipe 406 are both assembled on the injection mold 202, the ends of the front mold cooling pipe 405 and the rear mold cooling pipe 406 are fixedly assembled on the front guide ring 401, and the front mold cooling pipe 405 is connected to the first cavity 403, and the rear mold cooling pipe 406 is connected to the second cavity 404.

[0035] In actual application of this embodiment, the front guide ring 401 is fixedly arranged on one side of the mold frame 201, and the rear guide ring 402 is fixedly arranged on one side of the fixed cylinder frame 301, so that when the mold frame 201 rotates around the fixed axis, the front guide ring 401 rotates synchronously on the side of the rear guide ring 402, and a sliding sealing structure is adopted between the front guide ring 401 and the rear guide ring 402, so that the first cavity 403 and the second cavity 404 have independent cavity structures, and the front mold cooling pipe 405 and the rear mold cooling pipe 406 on the two groups of injection molds 202 are respectively connected to the two groups of cavities of the first cavity 403 and the second cavity 404, so that after the two groups of injection molds 202 rotate 180° in the yoz plane, the front mold cooling pipe 405 and the rear mold cooling pipe 406 on the two groups of injection molds 202 are always connected with the first cavity 403 and the second cavity 404, so as to facilitate the input of cooling water to cool the mold.

Several of the air cylinders 506 are fixedly arranged in the fixed cylinder frame 301. The air cylinder 506 is slidably equipped with an air rod 507, one end of the air rod 507 is connected to the secondary piston 508, and the other end of the air rod 507 is movably assembled on the traction disk 503. One side of the air cylinder 506 is also connected to the air inlet pipe 509 and the exhaust pipe 510, and the end of the exhaust pipe 510 is arranged in the locking sleeve 302.

[0037] In actual application of this embodiment, a plurality of the gas cylinders 506 are fixedly arranged in the fixed cylinder frame 301, and the gas cylinder 506 is slidably equipped with a gas rod 507 and a secondary piston 508. When the gas rod 507 moves toward the negative direction of the first direction x under the traction of the traction plate 503, the inner cavity of the gas cylinder 506 becomes a negative pressure state. At this time, the inner cavity of the gas cylinder 506 continuously inhales external air through the air inlet pipe 509, and when the gas rod 507 moves toward the positive direction of the first direction x under the push of the traction plate 503, the gas cylinder 506 is in a negative pressure state. During movement, the inner cavity of the air storage cylinder 506 becomes a positive pressure state, so that the air inside the air storage cylinder 506 flows along the exhaust pipe 510 to the locking sleeve 302, and at this time, the locking sleeve 302 and the sliding sleeve 303 are in a closed state, so that the gas pressure inside the locking sleeve 302 after the air is pumped in continues to increase. When the locking sleeve 302 and the sliding sleeve 303 are switched to a conducting state, the air released instantly can quickly flow along the injection hole 304 to the surface of the part, thereby achieving the purpose of air cooling.

[0038] See also Figure 8 In a preferred embodiment of the present invention, the automatic production equipment of the two-color injection molding machine further includes a driving assembly 6, which includes a spindle frame 601, a spindle disk 602, a traction arm 603, a second transmission shaft 604 and a residual tooth gear 605.

When the second transmission shaft 604 drives the residual tooth gear 605 to rotate, the transmission gear 105 can drive the first transmission shaft 104 to rotate with a delay, thereby making the spindle disk 602 rotate during the first stage of work, and the mold frame 2 01 remains stationary until the residual tooth gear 605 meshes with the transmission gear 105 and drives the mold frame 201 to rotate 180°, so that during the first working process of the two-color injection molding machine, the liquid storage cylinder 501 continuously pumps the high-temperature water in the second cavity 404 through the front suction pipe 504, and at the same time continuously presses air into the locking sleeve 302, until the second working process, the mold frame 201 makes the locking sleeve 302 and the sliding sleeve 303 conductive during the rotation process, so that the compressed gas can be quickly ejected and the parts can be cooled, until the third working process, the high-temperature water pumped inside the liquid storage cylinder 501 flows back to the first cavity 403 along the front discharge pipe 505, and enters the injection mold 202 along the first cavity 403, thereby completing the circulation of high-temperature water.

[0040] In one case of this embodiment, the front mold cooling pipe 405, the rear mold cooling pipe 406, the front suction pipe 504, the front exhaust pipe 505, the air inlet pipe 509 and the exhaust pipe 510 are all equipped with a one-way check valve to limit the fluid to flow in one direction along the first cavity 403 on the front mold cooling pipe 405 to the injection mold 202, to limit the fluid to flow in one direction along the injection mold 202 on the rear mold cooling pipe 406 to the second In the cavity 404, the fluid is limited to flow unidirectionally along the second cavity 404 on the front suction pipe 504 to the liquid storage cylinder 501, the fluid is limited to flow unidirectionally along the liquid storage cylinder 501 on the front discharge pipe 505 to the first cavity 403, the fluid is limited to flow unidirectionally along the air intake pipe 509 to the air storage cylinder 506 on the air intake pipe 509, and the fluid is limited to flow unidirectionally along the air storage cylinder 506 on the exhaust pipe 510 to the locking sleeve 302.
