By adopting the above technical scheme, the ring arrangement of a plurality of small injection modules is equivalent to a plurality of small injection modules working in parallel. In this way, compared with disassembling the traditional large multi-cavity mold into a single-cavity mold ring arrangement, the injection amount of each injection module is small, the flow channel is short, the required injection pressure and injection speed are low, the requirements for the mold are reduced, the mold structure is simple, the design and production cycle is short, the opening and closing of the mold, the cooling cycle, etc. are greatly shortened, the injection efficiency is improved, the injection energy consumption is reduced, and the equipment cost is correspondingly reduced.

[0004] The above-mentioned equipment has certain shortcomings when performing injection molding operations. When performing injection molding operations, the above-mentioned equipment needs to perform multiple steps such as mold closing, injection molding, cooling, shaping and demolding. The injection molding operation of subsequent products can only be carried out after one group of products has been processed. It does not have a high-speed injection molding structure, and cannot fully utilize the time of material cooling and demolding to perform continuous injection molding operations, which reduces its processing efficiency; secondly, the above-mentioned equipment does not have an auxiliary demolding structure. When performing high-speed injection molding operations, the cooled material is easily stuck inside the mold, making it impossible for the injection molding equipment to complete the demolding operation normally, affecting the stability of the injection molding equipment during use; secondly, when performing high-speed injection molding operations, the equipment continuously performs injection molding operations on multiple groups of molds, and after injection molding, it needs to complete material recovery operations for multiple groups of molds. It does not have an auxiliary material collection structure, and cannot complete the recovery of multiple groups of materials at the same time, which reduces its use effect. Summary of the invention

The rotation of the rotating plate can drive one end of the discharge plate to tilt up, so that the discharge plate can reciprocate, which is convenient for the discharge operation of the discharge plate.

[0016] A method for using a high-speed injection molding device comprises the following steps: Step 1: Use a motor and a gear to drive the sliding caster to rotate, so that the sliding caster drives the sliding seat to move along the limiting slide groove, move the injection nozzle to the top of a group of injection molds, insert the injection nozzle, and allow the extruder to introduce the molten plastic raw material into the interior of the injection mold through the injection nozzle; Step 2: Use the cooler to transport the coolant through the circulation pump, so that the coolant is transported to the infusion pipe through the connecting pipe, and then input into the cooling grooves of the front mold and the rear mold, and the coolant is discharged outward through the infusion pipe on the other side, and the used coolant is recovered by the connecting pipe, so that the material in the injection mold is cooled and shaped; Step three, use the lateral push rod to drive the front mold to separate the front mold and the rear mold, and complete the demoulding operation through the elastic frame and the demoulding top cap.

The motor cooperates with the gear to drive the sliding caster to rotate, so that the sliding caster drives the sliding card seat to move along the limiting slide groove. Because several groups of injection molds are provided, the use position of the injection nozzle can be adjusted arbitrarily by moving the sliding card seat, and the injection nozzle is moved to the top of a group of injection molds. During injection molding, the horizontal push rod is used to drive the moving slider, so that the moving slider drives the front mold to move along the sliding guide rod, so that the front mold and the rear mold are molded together, and the hydraulic rod is used to drive the lifting plate.

The horizontal push rod is used to drive the moving slider, so that the moving slider drives the front mold to move along the sliding guide rod, so that the front mold and the rear mold are separated. At this time, the top head loses the squeeze on the elastic top plate. Secondly, when the mold is closed, the elastic top plate can be driven by the top head, so that the elastic top plate drives the elastic frame to reset. The elastic frame is driven by the spring, and when the front mold and the rear mold are demolded and separated, the elastic frame can be used to drive the demolding top cap, so that the demolding top cap can eject the material stuck in the rear mold to complete its discharge operation. When the elastic frame moves on the inner side of the rear mold, a number of groups of rollers can be used to reduce the friction between the elastic frame and the rear mold.

[0019] 3. By setting a discharge plate and a rotating plate, when the high-speed injection molding equipment is used, it has an auxiliary discharge structure, and can perform discharge operations simultaneously when several groups of injection molds are used, thereby improving its discharge efficiency; During operation, when the front mold and the rear mold are separated, the elastic frame is used to drive the demoulding top cap to eject the formed material from the mold, so that the material falls downward to the upper end of the discharge plate.
