Description

TECHNICAL FIELD

[0001] The application relates to the technical field of injection molding machines, in particular to a horizontal double-station injection molding machine. BACKGROUND

[0002] The working principle of an injection molding machine is similar to that of a syringe for injecting medicine, that is, the plastic in a molten state is injected into a closed mold cavity by the pushing force of a screw or plunger, and the product is obtained after solidification and setting. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding, plasticizing, pressure injection, mold filling and cooling, mold opening and part taking. After the plastic part is taken out, the mold is closed again for the next cycle.

[0003] Most of the time of the injection molding machine is spent on mold opening, core pulling, thread stripping and ejection. When the above actions are performed, the plasticized raw material is in a waiting state in the barrel, and the work efficiency is low.

[0004] The application number of the national invention patent application for a double-station injection molding machine for plastics is 202010282375.7: an injection molding device and a molding device, characterized in that: the molding device comprises a rack, two slide rails are arranged on the front side of the injection molding device, a sliding plate is installed on the slide rails, and the sliding plate can move left and right intermittently under the drive of the driving device; a plurality of through holes are arranged on the sliding plate, and a molding mold that can be separated from the sliding plate is installed on each through hole; a cross beam extends above the middle part of the rack, and an injection gate is arranged below the middle part of the cross beam; the left or right movement of the sliding plate allows a set of molding molds to be located below the injection gate for injection molding operation, and the other set of molding molds deviating from the injection gate simultaneously performs mold opening and discharging operation; a lifting platform is arranged below the injection gate, and the lifting platform is lifted to pass through the through hole on the sliding plate and drive the molding mold thereon to rise and combine with the injection gate for injection molding operation.

[0005] The patent application is provided with two sets of molding molds arranged at intervals on the sliding plate, and at each processing time point, the two molding molds correspond to two stations of injection molding and mold opening and discharging, respectively, and after each left or right movement of the sliding plate, the two sets of molding molds sequentially rotate the corresponding stations, thereby realizing the synchronous operation of injection molding and mold opening and discharging, avoiding the idle time in the processing process, effectively improving the utilization rate of the equipment and the processing efficiency of the product.

[0006] However, the structure precision of the patent application scheme is poor, which cannot meet the actual production needs, and specifically, the following defects exist:

[0007] 1. The bottom die plate below the forming die and the lifting platform directly below have no positioning mechanism parts, which cannot guarantee no displacement during the injection process from disengaging the slide plate to locking the upper die plate, and the precision is poor.

[0008] 2. Two support rods are arranged on both sides of the forming upper die plate for separating the mold. Firstly, it is impossible to drill holes on the mold for secondary processing except for the reserved locking position, and secondly, the dislocation is easy to occur after lifting and then putting down the two side brackets, so the failure rate is high.

[0009] 3. The double-station device has no product taking-out mechanism, and the injection-molded products are all attached to the mold, which is difficult to take down and has low efficiency.

[0010] 4. The synchronization mechanism for lifting the upper forming part is an oil cylinder driving a connecting plate, and the connecting plate is positioned by guide sleeves. The installation error of each guide sleeve causes inconsistent friction after a period of use, and the phenomenon of jamming and not smooth occurs, which cannot guarantee the synchronous lifting of the four rods for a long time, affecting the service life.
