[0031] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0032] 1. This utility model, by setting an adjustment mechanism, uses a motor to drive the positive and negative threaded rods to rotate. The positive and negative threaded rods can drive the transmission block on the outer surface to move inward. The transmission block then drives the second fixing member, so that the second fixing member drives the first fixing member through the connecting rod. The first fixing member drives the baffle, causing the left baffle to move downward and the right baffle to move upward until the two baffles are in contact, thereby achieving the adjustment of the feeding port and realizing the effect of quantitative injection molding.

[0033] 2. This utility model, by setting up an impact component, a rebound component, a transmission component, and a fixing plate, allows a motor to drive a pulley to rotate, which in turn drives a transmission rod to rotate. The transmission rod then drives a notched gear on the outer surface to rotate. The rotating notched gear meshes with a toothed plate, causing the toothed plate to move outward. This movement of the toothed plate causes the impact component to move to the opposite side. The impact component compresses a telescopic spring, which generates elastic force. When the notched gear is not meshing with the toothed plate, the telescopic spring releases its elastic force, pushing the impact component to move back quickly. This causes the impact component to strike the outer surface of the feed port, thereby accelerating the entry of raw materials from the feed port into the injection molding mechanism.

[0072] The working principle of this utility model:

[0073] In operation, the raw material is poured into the feeding port 3. Once a certain amount of raw material has entered the injection molding mechanism 2, the motor 453 drives the positive and negative threaded rod 452 to rotate. The positive and negative threaded rod 452 drives the transmission block 451 on the outer surface to move inward.

The first fixing member 420 drives the baffle 410, causing the left baffle 410 to move downward and the right baffle 410 to move upward until the two baffles 410 are in contact. At the same time, the motor 453 drives the pulley 701 to rotate, which in turn drives the transmission rod 702 to rotate. The transmission rod 702 drives the missing gear 503 on the outer surface to rotate. The rotating missing gear 503 meshes with the toothed plate 502, causing the toothed plate 502 to move outward. The movement of the toothed plate 502 can drive the impact member 501 to move to the opposite side. The impact member 501 can squeeze the telescopic column 601 and the telescopic spring 602. The telescopic spring 602 can generate elastic force. When the missing gear 503 is not meshed with the toothed plate 502, the telescopic spring 602 can release the elastic force, pushing the impact member 501 to move back quickly, so that the impact member 501 impacts the outer surface of the feed port 3, accelerating the entry of the raw material inside the feed port 3 into the injection molding mechanism 2. Finally, the injection molding mechanism is started to complete the injection molding.

[0074] It should be noted that the motor 453 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 453 are clear to those skilled in the art, so they will not be described in detail.

[0075] In summary, this easily adjustable extrusion injection molding device for plastic production, through its body 1, injection mechanism 2, feeding port 3, adjustment mechanism 4, impact component 5, springback component 6, transmission component 7, fixed plate 8, and fixed sleeve 9, solves the problem that the lack of an adjustable structure inside the feeding port prevents quantitative injection of the extrusion injection molding device, causing all the raw materials to enter the injection mechanism, resulting in over-injection and waste of a large amount of raw materials.
