Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an alternating injection mold. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size.

A nut 12 is threadedly connected to the surface of the bolt 11, and the nut 12 is clamped on one side of the mounting seat 8.

[0026] The effect achieved by the above components is: by setting the bolts 11 and the nuts 12 to cooperate with each other to clamp the mounting block 9 into the inside of the mounting seat 8, it is convenient to replace the rotating plate 4, and then it is convenient to replace different types of mold mechanisms 3 for processing.

[0027] like Figure 3As shown, a track 13 is fixedly installed at the bottom of the rotating plate 4 , and two positioning support rods 14 are fixedly installed on the right side of the top of the base 1 , and the top of the positioning support rods 14 is located inside the track 13 .

[0029] like Figure 4 As shown in FIG. 5 , the mold mechanism 3 includes a fixed mold 301, which is fixedly mounted on the top of the rotating plate 4. A movable mold 302 is arranged above the fixed mold 301. Grooves are provided on both sides of the top of the fixed mold 301, and a compression spring 305 is fixedly installed inside the groove. The top of the compression spring 305 is fixedly connected to the bottom of the movable mold 302. An empty groove 306 is provided on the top of the fixed mold 301. A clamping plate 307 is fixedly installed on the bottom of the movable mold 302 and located just above the empty groove 306. The inner part of the empty groove 306 is fixedly connected to the bottom of the movable mold 302. The movable plate 308 is rotatably connected to the part, and a clamping block 309 is fixedly installed on the top of the movable plate 308.

[0030] The effects achieved by the above components are as follows: when the cylinder 6 drives the extrusion plate 7 to move downward, the extrusion plate 7 squeezes the movable mold 302 downward, and then the movable mold 302 moves downward to close the mold with the fixed mold 301, and the compression spring 305 is compressed to the inside of the groove, and the clamping plate 307 enters the inside of the empty groove 306 and squeezes the clamping block 309, so that the clamping block 309 rotates under the action of the extrusion force, and drives the movable plate 308 to rotate, and the movable plate 308 stretches the tension spring 310. When the bottom of the clamping plate 307 moves to the bottom of the clamping block 309, the stretched tension spring 310 pulls the movable plate 308 back to rotate, and the movable plate 308 is pulled back to rotate. The clamping block 309 is rotated and clamped on the clamping plate 307, so that the fixed mold 301 and the movable mold 302 are molded together, and then the raw material is injected into the cavity inside the fixed mold 301 and the movable mold 302 through the injection port. When the mold needs to be opened, the worker only needs to squeeze the extrusion rod 311 so that the extrusion rod 311 squeezes the movable plate 308, so that the movable plate 308 rotates, and the movable plate 308 drives the clamping block 309 to rotate and gradually separate from the clamping plate 307. When the clamping block 309 is completely separated from the clamping plate 307, the movable mold 302 is bounced upward under the elastic force of the compression spring 305, completing the mold opening of the fixed mold 301 and the movable mold 302.

[0032] The effects achieved by the above components are: by setting the positioning rod 304 and the positioning hole to cooperate with each other to position the movable mold 302, the mold clamping accuracy of the movable mold 302 and the fixed mold 301 is ensured, and the top of the movable mold 302 is protected under the action of the protective pad 303 to prevent the extrusion plate 7 from causing damage to the surface of the movable mold 302 when squeezing the movable mold 302.

[0033] The working principle of this alternating injection mold:

[0034] The motor 201 drives the driving gear 202 to rotate, and then the driving gear 202 drives the driven gear 204 to rotate, and the driven gear 204 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the rotating plate 4 to rotate, so that the rotating plate 4 drives the mold mechanism 3 to rotate, so that the cylinder 6 drives the extrusion plate 7 to extrude and close the mold mechanisms 3 on the rotating plate 4 one by one. When the cylinder 6 drives the extrusion plate 7 to move downward, the extrusion plate 7 squeezes the movable mold 302 downward, and then the movable mold 302 moves downward to close the mold with the fixed mold 301, and the compression spring 305 is compressed to the inside of the groove, and the clamping plate 307 enters the inside of the empty groove 306 and squeezes the clamping block 309, so that the clamping block 309 rotates under the action of the extrusion force, and drives the movable plate 308 to rotate, and the movable plate 308 squeezes the tension spring When the bottom of the card plate 307 moves to the bottom of the card block 309, the stretched tension spring 310 will pull the movable plate 308 back and rotate, and then rotate the card block 309 and clamp it on the card plate 307, so that the fixed mold 301 and the movable mold 302 are molded together, and then the raw material is injected into the cavity inside the fixed mold 301 and the movable mold 302 through the injection port. When the mold needs to be opened, the worker only needs to squeeze the extrusion rod 311 so that the extrusion rod 311 squeezes the movable plate 308, so that the movable plate 308 rotates, and the movable plate 308 drives the card block 309 to rotate and gradually separate from the card plate 307. When the card block 309 is completely separated from the card plate 307, the movable mold 302 is bounced upward under the elastic force of the compression spring 305, completing the mold opening of the fixed mold 301 and the movable mold 302.
