Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding device for an amusement boat shell with a circulation cooling function. Background Art

[0002] Injection molding equipment is a general term for various equipment required in the injection molding process. They occupy a pivotal position in the manufacturing industry and are widely used in many fields such as automobiles, home appliances, packaging, 3C consumer electronics, and building materials. The injection molding machine is an important molding equipment used to melt plastic by heating and applying a certain pressure to fill the high-temperature melt into the mold, and then cool and solidify it to make plastic products with certain geometric shapes and dimensional accuracy. The working principle of the injection molding machine is similar to that of a syringe. Under the push of the screw, plastic is injected into the closed mold cavity, and solidified and shaped in the closed mold cavity to obtain the product. This process mainly includes four stages: filling, pressure holding, cooling, and demolding. It is a complete and continuous process.

[0003] Injection molding is a common plastic molding process, but many defects may occur during the production process. When there are residual impurity particles on the injection mold, it will cause internal defects in the injection molded plastic parts. During injection molding, the molten raw material filled is insufficient, resulting in missing and incomplete plastic parts. The plastic parts are cooled unevenly, and there will be stratification between the areas that cool too fast and the areas that cool too slowly, which will cause defects inside the molded plastic parts and greatly reduce the structural strength.

The outer frame contacts the mold back plate first, and the slide mechanism pushes to contact the mold back plate. The molten plastic is injected into the space between the mold mechanism and the mold back plate through the injection port.

[0045] Before injection molding, the external air source passes through the air inlet valve 665 through the third through hole 66242 and the one-way valve 6634 to clean the residual particles and dust on the mold groove plate 6633. During injection molding, the first inclined groove 66243 contacts the second inclined groove 66331, and the inner slide 6624 is sealed with the slide cylinder 6632 and the mold groove plate 6633. The external air source passes through the air inlet valve 665 through the third through hole 66242 to ventilate the mold groove plate 6633 to cool the injection molded part as a whole. The local cooling condition on the mold groove plate 6633 is identified by the temperature sensor 6635, and an electrical signal is generated to the ventilation mechanism 664. During demolding, the third cylinder 6631 pulls the slide cylinder 6632 to slide in the cylinder cavity 66244 toward the third cylinder 6631. The redundant part of the injection molded part is restricted by the inner slide 6624, and the injection molded part is separated from the mold groove plate 6633.

[0046] like Figure 7 , Figure 8 As shown, the ventilation mechanism 664 includes a third motor 6641, a first gear 6642, a ring platform 6643, a ring frame 6644 and a two-way valve 6645. The third motor 6641 and the ring frame 6644 are fixedly connected to the inner slide 6624. The output end of the third motor 6641 is fixedly connected to the first gear 6642. The ring platform 6643 is provided with a pressure relief hole 66431, a square hole 66432 and a gear pair 66433. The pressure relief hole 66431 is provided with a plurality of groups of , several groups of pressure relief holes 66431 are evenly distributed along the circumference of the ring platform 6643, the first gear 6642 is meshed with the tooth surface of the gear pair 66433, the ring platform 6643 is rotatably connected to the ring frame 6644, the square hole 66432 is arranged between two adjacent groups of pressure relief holes 66431 on the ring platform 6643, several groups of two-way valves 6645 are arranged, the two-way valves 6645 are fixedly connected to the ventilation holes 66245, and the third motor 6641 is connected to the temperature sensor 6635 through electrical signals.

[0047] During injection molding, the pressure relief hole 66431 is aligned with the ventilation hole 66245, and the sealed air between the inner slide 6624 and the slide cylinder 6632 and the mold groove plate 6633 expands due to temperature rise and is discharged through the two-way valve 6645 and the ventilation hole 66245. When the local temperature on the mold groove plate 6633 is uneven, the temperature sensor 6635 identifies the local temperature drop on the mold groove plate 6633, and generates an electrical signal to the third motor 6641. The third motor 6641 outputs a fixed shaft torque to the first gear 6642. The first gear 6642 meshes with the tooth surface of the gear pair 66433, and the ring table 6643 rotates along the ring frame 6644. The square hole 66432 is aligned with the ventilation hole 66245 corresponding to the uneven temperature drop area, and the external wind source cools the uneven temperature drop area through the air intake valve 665 through the ventilation hole 66245 and the two-way valve 6645 corresponding to the uneven temperature drop area.

[0048] Working principle of the present invention: The present invention is a device for making plastic parts of the outer shell of an amusement boat by injection molding and demolding. The first cylinder 2 pulls the outer cylinder 451, the tapered mouth 4511 contacts the outer cylinder 451, and the raw material falls onto the feeding worm 453 through the discharge port 4512. The first motor 43 outputs torque to the feeding worm 453, the heating coil 452 heats the plastic raw material to a molten state, the feeding worm 453 rotates to feed the plastic raw material into the injection port 651, the second cylinder 62 pushes the outer frame 661 to contact the mold back plate 65, and the second motor 6621 outputs torque to the feeding worm 453. The torque is output to the first worm 6622, and the inner slide 6624 is pushed to contact the mold back plate 65 through the threaded connection between the first worm 6622 and the internal threaded hole 66231. The water source continuously inputs flowing liquid to the cooling pipe 6625 through the first water pipe hole 6612 through the hose. The circulating liquid takes away the heat on the inner slide 6624 and flows out through the hose through the second water pipe hole 6613. The molten plastic between the mold mechanism 663 and the mold back plate 65 is redundant to the groove 66246, so as to avoid the injection molded parts from being molded incompletely due to insufficient feeding. Before injection molding, the air source passes through the air inlet valve 665 through the third through hole 66242 and the one-way valve 6634 to clean the residual particles and dust on the mold slot plate 6633. During injection molding, the air source passes through the air inlet valve 665 through the third through hole 66242 to ventilate the mold slot plate 6633 to cool the injection molded part as a whole. The temperature sensor 6635 identifies the local cooling condition on the mold slot plate 6633 and generates an electrical signal to the third motor 6641. The third motor 6641 outputs torque to the first gear 6642. The first gear 66 42 meshes with the tooth surface of the gear pair 66433, the ring table 6643 rotates along the ring frame 6644, the square hole 66432 is aligned with the ventilation hole 66245 corresponding to the uneven cooling area, and the air source cools the uneven cooling area through the ventilation hole 66245 and the two-way valve 6645 via the air intake valve 665. During demoulding, the third cylinder 6631 pulls the slide 6632 to slide in the cylinder cavity 66244 toward the third cylinder 6631, and the redundant part of the injection molded part is restricted by the inner slide table 6624, and the injection molded part is separated from the mold groove plate 6633.
