Description

Technical Field

[0001] This utility model belongs to the technical field of injection mold processing equipment, specifically an injection mold material guiding mechanism. Background Technology

[0002] A combined injection mold for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding mainly includes a cavity mold with a variable cavity, consisting of a cavity mold assembly base plate, a cavity mold assembly, and a cavity mold assembly clamping plate; and a punch with a variable core, consisting of a punch assembly base plate, a punch assembly, a punch assembly clamping plate, a cavity cut-off assembly, and a side cut-off assembly plate. The coordinated changes of the punch, cavity mold, and auxiliary molding system can process a series of plastic parts of different shapes and sizes.

[0003] A search revealed that Chinese patent CN212194020U discloses an injection mold with a slurry guiding mechanism. This mold includes a material guiding component. After the material enters the guide cylinder, it passes through the discharge hole and corresponding holes to enter the lower mold, thus guiding the material more evenly and facilitating injection. This also prevents material splashing during injection, avoiding waste. After injection, the guide cylinder can be quickly closed to prevent excessive material injection and waste, while also facilitating subsequent injection into the lower mold, improving injection efficiency and overall work efficiency. However, because the material is guided downwards through the guide cylinder, in low ambient temperatures, the material inside the cylinder loses its fluidity and gradually solidifies, causing material accumulation at the injection port and affecting injection into the mold.

By setting the baffle 24, when it is necessary to introduce material into the connecting shell 4, the drive motor 23 is started first to flip the baffle 24, so that the feed frame 20 is opened. Then, the material is introduced into the connecting shell 4 through the feed frame 20. While the material is being squeezed and injected into the injection mold body 1, the drive motor 23 can be started again to rotate and close the baffle 24, so as to prevent excess material from entering the interior of the connecting shell 4 through the feed frame 20.

[0027] Example 3

[0028] Based on Embodiment 1 or 2, refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 A rubber block 12 is fixedly installed on one side of the push plate 11.

[0029] Working principle: Please refer to Figures 1-6When it is necessary to introduce material into the connecting shell 4, first start the drive motor 23 to flip the baffle 24, so that the feed frame 20 opens. Then, introduce the material into the connecting shell 4 through the feed frame 20. After the material is introduced into the connecting shell 4, the drive motor 23 can be started again to rotate and close the baffle 24, preventing excess material from entering the interior of the connecting shell 4 through the feed frame 20. By starting the electric push rod 8, the telescopic shaft of the electric push rod 8 drives the connecting cylinder 9 and the mounting column 10 to retract. At the same time as the mounting column 10 retracts, the push plate 11 will push the material in the connecting shell 4. During the extrusion process, the rubber block 12 on the push plate 11 can fit against the inner wall of the connecting shell 4.
