Description

Technical Field

[0001] This utility model relates to the field of injection device technology, specifically to an injection device for molding connector components. Background Technology

[0002] The microchannel tooth pitch of the liquid-cooled plate is on the order of 0.1mm (compared to millimeters for air-cooled plates), requiring more precise design and manufacturing to consider flow channels and flow resistance. The water-cooled plate and mounting plate are integrated, ensuring no leakage. Each liquid-cooled server has one inlet and one outlet water pipe, and at least four connectors, making them high-precision quick-connect components. Strict control is required at every stage of the liquid-cooled connector manufacturing process. Further processing follows injection molding. In injection molding, granular materials are conveyed, heated to a molten state, and then formed.

[0003] In existing injection molding machines, the screw barrel is responsible for conveying and plasticizing the raw materials. It is equipped with an open hopper and a fixed feed pipe. The hopper is a single conical structure used only for storing raw materials, without any auxiliary mechanisms to prevent material from becoming brittle. The raw materials slide down the conical wall of the hopper under their own weight and enter the screw barrel through the fixed feed pipe. The hopper lacks any stirring or anti-bridging mechanisms. At the bottom of the hopper cone or the outlet, the raw materials are prone to bridging due to friction and adhesion between particles. Some devices incorporate stirring structures, but these affect the feeding from the top of the hopper, requiring improvement. To address these issues, an injection molding machine for connector component molding is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an injection device for molding connector components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An injection apparatus for molding connector components, including a base and an injection mechanism mounted on top of the base;

[0007] It also includes a feeding mechanism for feeding material into the injection mechanism, a stirring mechanism for stirring and breaking up the arches of the material in the feeding mechanism, a support frame mounted on the machine base, and a switching mechanism for adjusting the horizontal movement of the feeding mechanism.

[0008] The feeding mechanism includes a hopper and a sliding seat connected to the bottom of the hopper; the actuating mechanism includes three sets of actuating blades, each set of actuating blades is connected to a round rod on one side, and the tops of the three round rods are connected by a conical block. The bottom of the actuating blades extends to the inner wall of the discharge port at the bottom of the hopper, and the actuating blades slide in contact with the inner wall of the hopper. The top of the hopper is rotatably connected to a toothed ring, the bottom of the toothed ring is connected to the top of the actuating blades, and a driving component for driving the toothed ring to rotate is installed on one side of the hopper.

[0009] In one alternative embodiment: the injection mechanism includes a control seat mounted on the top of the base and a screw injection seat mounted on one side of the control seat. A guide strip is connected to the top feed port of the screw injection seat near the control seat. The guide strip has a feed port in the middle that communicates with the feed port of the screw injection seat. The sliding seat has a through hole that communicates with the feed port and the bottom discharge port of the hopper. The sliding seat is slidably engaged with the guide strip.

[0010] In one alternative: one end of the guide strip is connected to a drain pipe, and the guide strip has a circular hole communicating with the drain pipe, the circular hole being a through hole.

[0011] In one alternative embodiment: the drive unit includes a mounting bracket installed on one side of the hopper, a drive component is mounted on the mounting bracket, a gear that meshes with the outer ring of the gear ring is connected to the output shaft of the power output end of the drive component, and a protective cover for protecting the gear ring and the gear is connected to the top of the hopper.

[0013] In one alternative: the switching mechanism includes a hydraulic telescopic rod mounted on the frame, a fixed frame mounted on one side of the hopper, and a piston rod at the power output end of the hydraulic telescopic rod connected to the fixed frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the rotating stirring of the material-pushing plate in the stirring mechanism reduces the problem of material bridging in the hopper due to particle adhesion, static electricity, or differences in bulk density, ensuring that the material continuously and evenly enters the screw injection seat, and avoiding injection interruption or product defects caused by material shortage.

[0016] In this invention, the switching mechanism can switch the discharge state of the hopper, which facilitates quantitative feeding. When used in conjunction with the impurity discharge pipe, it can quickly switch to the impurity discharge state to discharge impurities, lumps, or residues in the hopper, thereby reducing the interference of impurities on the plasticizing process.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 In this embodiment, the injection device for molding connector components includes a base 1 and an injection mechanism 2 mounted on the top of the base 1; the injection mechanism 2 can heat and melt the material and inject it into the cavity of the molding equipment for molding.

[0025] It also includes a feeding mechanism 3 for feeding material into the injection mechanism 2, a stirring mechanism 4 for stirring and breaking up the arches of the material in the feeding mechanism 3, a support frame 5 mounted on the base 1, and a switching mechanism 6 for adjusting the horizontal movement of the feeding mechanism 3.

[0026] The feeding mechanism 3 includes a hopper 31 and a sliding seat 32 connected to the bottom of the hopper 31;

[0027] The actuating mechanism 4 includes three sets of agitator plates 41. Each set of agitator plates 41 is connected to a round rod 42 on one side. The top ends of the three round rods 42 are connected by a conical block 43. The bottom end of the agitator plate 41 extends to the inner wall of the bottom outlet of the hopper 31, and the agitator plate 41 slides in contact with the inner wall of the hopper 31. The top of the hopper 31 is rotatably connected to a toothed ring 44. The bottom of the toothed ring 44 is connected to the top of the agitator plate 41. A driving component for driving the toothed ring 44 to rotate is installed on one side of the hopper 31. The driving component drives the toothed ring 44 to move. The agitator plate 41 and the round rod 42 can stir the material, reduce the problem of material bridging in the hopper 31 due to particle adhesion, static electricity or difference in bulk density, and ensure that the material continuously and evenly enters the screw injection seat 22, avoiding injection interruption or product defects caused by material shortage.

[0028] In another embodiment, the injection mechanism 2 includes a control seat 21 mounted on the top of the base 1 and a screw injection seat 22 mounted on one side of the control seat 21. The top feed port of the screw injection seat 22 near the control seat 21 is connected to a guide bar 23. The guide bar 23 has a feed port in the middle that communicates with the feed port of the screw injection seat 22. The sliding seat 32 has a through hole that communicates with the feed port and the bottom discharge port of the hopper 31. The sliding seat 32 is slidably engaged with the guide bar 23.

[0029] Specifically, when the hopper 31 moves to the top of the feed inlet, the screw injection seat 22 can be fed. When the hopper 31 moves and the through hole is misaligned with the feed inlet, the feeding can be stopped.

[0030] Furthermore, one end of the guide bar 23 is connected to the discharge pipe 24. The guide bar 23 is provided with a round hole that communicates with the discharge pipe 24. The round hole corresponds to the through hole. When the hopper 31 moves to the top of the discharge pipe 24, excess material in the hopper 31 can be discharged.

[0031] In another embodiment, the drive unit includes a mounting bracket 47 installed on one side of the hopper 31, on which a drive component 46 is mounted. A gear 45 that meshes with the outer ring of the gear ring 44 is connected to the output shaft of the power output end of the drive component 46. A protective cover for protecting the gear ring 44 and the gear 45 is connected to the top of the hopper 31. The drive component 46 can be a combination of an existing motor and a reducer, and the specific type can be selected according to actual needs. Specifically, the drive component 46 drives the gear 45 to rotate, which can drive the gear ring 44 to rotate stably on the top of the hopper 31.

[0032] In another embodiment, the support frame 5 includes a frame 51 mounted on the base 1, and the two sides of the hopper 31 are slidably engaged with the top crossbar of the frame 51; the frame 51 can support the horizontal movement of the hopper 31.

[0033] In another embodiment, the switching mechanism 6 includes a hydraulic telescopic rod 61 mounted on the frame 51, and a fixing frame 62 is mounted on one side of the hopper 31. The piston rod at the power output end of the hydraulic telescopic rod 61 is connected to the fixing frame 62. Specifically, by controlling the movement of the hydraulic telescopic rod 61, the fixing frame 62 drives the hopper 31 to move under the drive of the hydraulic telescopic rod 61, thereby switching the position of the hopper 31.

[0034] The working principle of this utility model is as follows: the guide strip 23 cooperates with the through hole of the sliding seat 32 to form a closed conveying channel for material from the hopper 31 to the screw injection seat 22 for material conveying. The screw inside the screw injection seat 22 conveys the material from the feeding mechanism 3 forward by rotating. At the same time, the material is melted and plasticized by the shearing and friction between the screw and the barrel. Finally, under pressure, the plasticized material is injected into the cavity of the molding equipment. The driving component 46 drives the gear 45 to rotate, which can drive the gear ring 44 to rotate stably at the top of the hopper 31. The material stirring plate 41 and the round rod 42 can stir the material, reduce the problem of material bridging in the hopper 31 due to particle adhesion, static electricity or difference in bulk density, and ensure that the material continuously and evenly enters the screw injection seat 22, avoiding injection interruption or product defects caused by material interruption. The material can be stirred before and after feeding.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
