Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 , a mold mounting seat for an injection molding machine to prevent mold offset, including a fixed mold mounting seat 1. An injection pipe mounting port 2 is provided at the center of the fixed mold mounting seat 1. Four adjustment grooves 3 are provided on one side of the fixed mold mounting seat 1. The four adjustment grooves 3 are arranged horizontally and in a rectangular arrangement. A positioning part 4 for clamping the fixed mold 5 is detachably connected in the adjustment groove 3. Positioning rods 6 are provided on the upper and lower sides of the injection pipe mounting port 2 on the fixed mold mounting seat 1. The positioning rods 6 and the adjustment grooves 3 are on the same side of the fixed mold mounting seat 1. An infrared emitter is provided on the end face of the positioning rod 6. The centers of the two positioning rods 6 coincide with the center of the injection pipe mounting port. One end of the fixed mold 5 is provided with a feeding port 7 matching the injection pipe mounting port 2. Positioning grooves 8 are provided on the upper and lower sides of the fixed mold 5 at the feeding port. The positioning grooves 8 correspond to the positioning rods 6 one by one, and infrared receivers are provided in the positioning grooves 8. The infrared emitter is used to emit infrared rays, and the infrared receiver is used to receive the emitted infrared rays to achieve quick alignment. By providing positioning rods 6 on the upper and lower sides of the injection pipe mounting port 2, infrared emitters are provided on the positioning rods 6, and the centers of the positioning rods 6 and the injection pipe mounting port 2 are on the same straight line, that is, three points are on a straight line. At the same time, positioning grooves 8 matching the positioning rods 6 are provided on one side of the fixed mold 5, and infrared receivers are provided in the positioning grooves 8. When the fixed mold 5 is installed by a manipulator, the fixed mold 5 can be quickly aligned with the fixed mold mounting seat 1, and during the process of the fixed mold 5 approaching the fixed mold mounting seat 1, due to the action of the upper and lower infrared sensors, the fixed mold can be in a vertical state without tilting, so that the fixed mold can be accurately and quickly installed on the fixed mold mounting seat 1.

[0023] In this embodiment, the adjusting groove 3 includes a strip-shaped groove 301 and a circular groove 302 communicating with the strip-shaped groove. The upper and lower sides in the strip-shaped groove 301 are respectively provided with sliding grooves 303 extending upward and downward, and the sliding grooves 303 communicate with the circular groove 302. The positioning portion 4 includes an arcuate pressing plate 401. A strip-shaped hole 402 is provided on the arcuate pressing plate 401. A screw rod 403 is slidably arranged in the strip-shaped hole 402. One end of the screw rod 403 is connected with a sliding plate 404. The sliding plate 404 can enter from the circular groove 302, and the sliding plate 404 can slide in the sliding groove 303. The outer end of the screw rod 403 is connected with a first nut 405. By screwing the first nut 405, it can be pressed against both sides of the strip-shaped hole 402. One end of the arcuate pressing plate 401 is provided with a pressing portion 406, and the pressing portion 406 presses on the side edge of the fixed mold 5. The other end of the arcuate pressing plate 401 is provided with a round hole, and an auxiliary screw rod 407 is inserted in the round hole. The outer end of the auxiliary screw rod 407 is threadedly connected with a second nut 408. When installing the positioning portion 4, the sliding plate 404 at the end of the screw rod 403 is inserted from the circular groove 302, and then pushed towards the strip-shaped groove 301 side, so that the sliding plate 404 slides in the sliding groove 303. Through the action of the sliding groove 303 and the sliding plate 404, it can prevent the screw rod 403 from falling off from the adjusting groove 3. When installing the fixed mold 5, since the diameters of the fixed molds 5 are different, therefore, according to the fixed molds with different diameters, the first nut 405 is loosened, the position of the screw rod 403 is adjusted, and then the fixed mold 5 is installed on the fixed mold mounting seat 1 by a manipulator, so that the pressing portion 406 presses on the edge of the fixed mold 5, and then the first nut 405 is tightened to make the pressing portion 406 tightly press on the fixed mold 5. Then the auxiliary screw rod 407 is inserted and the second nut 408 is tightened. That is, through the dual action of the screw rod 403 and the auxiliary screw rod 407, it can prevent the positioning portion 4 from rotating in the adjusting groove 3 and improve the stability.

[0024] In this embodiment, the injection pipe installation port 2 is conical, and a first sealing ring 9 is provided on its inner wall. Correspondingly, the end face of the injection pipe is also conical to increase the contact area with the fixed mold mounting seat. The first sealing ring 9 can play a sealing role to prevent the raw material from leaking from the injection pipe installation port 2.

[0025] In this embodiment, a molding cavity 10 is provided in the fixed mold 5. A second sealing ring 11 is provided on the fixed mold 5 around the periphery of the molding cavity. A plurality of positioning holes 12 are provided on the fixed mold 5 around the periphery of the second sealing ring. Opposite to the fixed mold, there is also a moving mold. Through a driving device, such as a hydraulic cylinder, etc., the moving mold is driven to move towards the fixed mold 5, and the moving mold and the fixed mold 5 are closed. At this time, the moving mold and the fixed mold can be connected through the positioning holes 12, and the second sealing ring 11 can keep the moving mold and the fixed mold sealed. After the raw material enters the fixed mold and the moving mold from the feed port 7, it is molded in the molding cavity.

[0026] Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 lies in that a fixing base 13 is connected to the bottom of the fixed mold mounting base 1, and a screw hole is formed in the fixing base 13. The fixed mold mounting base 1 can be mounted on an injection molding machine through the fixing base 13 to keep it fixed.
