The specific contents are as follows:

[0017] 1. When demoulding is required, the support plate is driven to rise by the support rod, so that the support plate lifts the top column and allows the top column to lift the sole. When the photosensitive probe senses the first light source, the motor stops and the top column stops rising. At this time, by blowing cold air into the ventilation slot, the mold itself is cooled down, which indirectly promotes the cooling and hardening of the plastic. The cold air is allowed to contact the plastic through the gap between the top column and the mounting block through the ventilation pipe, directly accelerating the cooling of the plastic. Then the motor is started again to make the top column rise and further lift the plastic until the photosensitive probe senses the second light source. At this time, the motor stops, the plastic further hardens and can be taken out, and the cold air will continue to cool the mold, accelerating the hardening of the plastic during the next injection. Lifting the plastic in batches and continuous air cooling can avoid the problem of deformation of the plastic due to incomplete hardening and continuous lifting and demoulding.

[0018] 2. By inserting the insertion rod into the limit sleeve, and then pulling the pull rod outward to disengage the hook rod from the engagement block, and then starting the motor to raise the lifting plate, the insertion rod is inserted into the through hole and the mold is lifted up to achieve rapid disassembly of the mold, avoiding the problem of it being too tightly fitted with the mounting block, making it difficult to disassemble and replace.

[0030] The top surface of the lifting plate 205 is fixedly connected to a plurality of limiting sleeves 209, and a through hole 211 is provided on the bottom surface of the mounting block 102 and below the mold 103, and an insert rod 210 can be inserted between the through hole 211 and the limiting sleeve 209; a reversal window is provided on the front side of the shell 101, and by opening the reversal window of the shell 101 and inserting the insert rod 210 into the limiting sleeve 209, the lifting plate 205 pushes the insert rod 210 into the through hole 211 when rising, thereby lifting the mold 103.

[0031] The bottom surface of the mold 103 is provided with a top column 216 overlapping the mounting block 102, and a first spring 215 is fixedly connected between the bottom of the top column 216 and the bottom surface of the mounting block 102. Ventilation slots 217 located inside the mounting block 102 are opened on both sides of the mold 103, and a ventilation pipe 214 is fixedly connected to the middle of the ventilation slot 217. The ventilation slot 217 passes through the shell 101 and can be connected to an external fan, and the ventilation pipe 214 passes through the bottom surface of the mounting block 102; one end of the ventilation slot 217 is fixedly connected with a connecting pipe, which can be connected to the hose of the external fan, so that the external fan blows cold air into the ventilation slot 217, and the ventilation slot 217 fits with both sides of the mold 103. The first spring 215 can push the top column 216 to reset.

[0032] The support rod 204 is penetrated by a horizontal plate 212 fixedly connected to the shell 101, and the two sides of the horizontal plate 212 are penetrated by second support columns 213, the top end of the second support column 213 is fixedly connected to the mounting block 102, and the bottom end of the second support column 213 is fixedly connected to the shell 101; the second support column 213 can increase the stability of the lifting plate 205 when it is raised or lowered.

[0036] Working principle: Before using this kind of double sole mold material synchronous ejection structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, when demoulding is required, the motor is first started to rotate the screw rod 201, so that the screw sleeve 202 drives the lifting plate 205 to rise through the support rod 204, so that the lifting plate 205 lifts the top column 216 to rise and the top column 216 lifts the sole, and when the light-sensitive probe 207 senses the first light source 208, the motor stops and the top column 216 stops rising;

[0037] At this time, by blowing cold air into the ventilation slot 217, the mold itself is cooled down, which indirectly promotes the cooling and hardening of the plastic. The cold air is allowed to contact the plastic through the gap between the top column 216 and the mounting block 102 through the ventilation pipe 214, which directly accelerates the cooling of the plastic. Then, the motor is started again to make the top column 216 rise, further lifting the plastic until the photosensitive probe 207 senses the second light source 208. At this time, the motor stops, the plastic further hardens and can be taken out, and the cold air will continue to cool the mold 103, accelerating the hardening of the plastic during the next injection molding.

[0038] If the mold 103 needs to be removed, first insert the insertion rod 210 into the limiting sleeve 209, then pull the pull rod 305 outward to disengage the hook rod 304 from the engagement with the locking block 301, and then start the motor to raise the lifting plate 205, so that the insertion rod 210 is inserted into the through hole 211 and the mold 103 is lifted up.
