[0015] Working principle: first start the hydraulic cylinder to drive the push rod to slide on the inner wall of the support plate, then the push rod drives the first rack and the second rack to drive the first gear and the second gear to rotate, and during use, the second gear and the first gear respectively drive the second connecting rod and the first connecting rod to rotate on the inner wall of the support plate, and during use, the second connecting rod drives the third connecting rod under the limit of the limit synchronization rod, and the first connecting rod directly drives the driving plate to expand and contract outward, and during use, the mold and the sleeve mold can be controlled to automatically close and open the mold, and then the plastic particles are poured into the injection conveying barrel. During use, the first motor drives the belt and the second rotating roller to drive the first driving rod to automatically move on the inner wall of the injection conveying barrel, and the particles are crushed by the crushing knife. During use, the plasticizing pretreatment can be further guaranteed to ensure the consistency of particle size, and the synchronization of melting time can be ensured during hot melt conveying. During injection molding, the motor drives the third gear to rotate, and the third gear drives the third rack and the gear ring to rotate inside the second connecting sleeve and the slide groove. During use, the third rack controls the opening and closing of the sealing plate on the inner wall of the mold, so that the injection molding chamber can be sealed during injection molding. During use, after the mold sleeve and the mold are molded together and the injection molding is cooled, the mold moves backward under the drive of the driving plate, and the motor drives the third gear and the gear ring to rotate and synchronously drives the other third gears to rotate, and then synchronously drives the third rack to drive the sealing plate to open and close, and move backward through the mold and limit it through the limit ejector rod. During use, the spring is compressed by the first connecting sleeve on the right side of the mold compression, and then the limit ejector rod slides into the inner wall of the mold and passes through the inner wall of the second connecting sleeve to be ejected forward, which has the effect of automatic demoulding during use. The removed injection molded product will fall down and be caught by the collection table at this time. Afterwards, the electric slider slides above the electric slide rail and drives the support seat to slide on the inner wall of the shell, and the second motor drives the second driving rod. At this time, the second driving rod drives the unloading rods on both sides to drive the collecting table to flip to one side under the limit of the support seat. During use, the adjusting rod is pushed to clamp one side and flip it to the other side. During use, the unloading angle can be adjusted according to the needs. During use, the device not only achieves the effect of automatic mold closing and opening, but also has the effect of automatic demoulding, and the unloading angle can be adjusted according to the needs during use.

[0016] The present invention provides an automatic control device for injection molding structure, which has the following beneficial effects:

[0017] 1. The present invention drives the push rod to slide on the inner wall of the support plate through a hydraulic cylinder, drives the first rack and the second rack to drive the first gear and the second gear to rotate, and drives the second connecting rod and the first connecting rod to rotate on the inner wall of the support plate through the second gear and the first gear respectively, and drives the third connecting rod under the limit of the limit synchronization rod through the second connecting rod, and the first connecting rod directly drives the driving plate to expand and contract outward, so that the mold and the sleeve mold can be controlled to automatically close and open the mold during use.

[0018] 2. The present invention compresses the spring by compressing the first connecting sleeve on the right side of the mold. At this time, the limiting ejector rod slides into the inner wall of the mold and passes through the inner wall of the second connecting sleeve to be ejected forward, which plays the role of automatic demolding during use. The removed injection molded product will fall downward and be caught by the collecting table to complete automatic unloading, and then move outward through the collecting table to prevent workers or operators from entering the mold opening area and causing mechanical injuries.

[0019] 3. The present invention drives the second driving rod through the second motor. At this time, the second driving rod drives the unloading rods on both sides to drive the collecting table to flip to one side under the limit of the support seat. During use, the adjusting rod can be pushed to lock one side to flip to the other side. During use, the unloading angle can be adjusted according to the needs of use.
