Description

Technical Field

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

[0002] Industrial connector injection molding equipment is the core equipment in industrial connector production. It mainly consists of injection, mold closing, heating and cooling, hydraulic lubrication, and electrical safety systems. The injection system uses components such as a hopper and screw to plasticize the plastic and inject it into the mold cavity. The mold closing system ensures precise mold opening and closing and product molding. The heating and cooling system controls the process temperature. The hydraulic lubrication system provides power and component protection. The electrical safety system ensures stable equipment operation and personnel safety. Its workflow covers raw material drying and mixing pretreatment, plastic heating and plasticizing, injection, pressure holding and cooling molding, and demolding and part removal. Combining electric servo motors, intelligent monitoring, and new mold technologies, it can achieve high-precision and high-efficiency production, meeting the performance requirements of connectors in the industrial field. It is a key molding and processing equipment in intelligent manufacturing systems.

[0003] However, existing technologies mostly use fixed-position air blowing or natural cooling to cool the mold. Fixed air blowing can cause localized rapid cooling of the mold while other areas cool slowly, resulting in uneven heating of the mold. This not only prolongs the cooling and setting time of the product, but also the traditional ejection mechanism is a simple cylinder ejection, which is prone to impact and vibration during the ejection process, which may cause damage to the product or displacement within the mold, resulting in defective products. Those skilled in the art provide an industrial connector injection molding device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an industrial connector injection molding device to solve the problems in the prior art.

[0005] This utility model provides the following technical solution: an industrial connector injection molding device, including a bearing structure for supporting the internal structure, a lifting structure for lifting the connector mold inside the bearing structure, and a blowing structure for cooling the mold on the top of the bearing structure;

[0006] The blower structure includes a top plate, a horizontal frame fixedly connected to the top of the top plate, a sliding groove inside the horizontal frame, a support frame fixedly connected to the top of the top plate, a second motor fixedly installed on the top of the support frame, a first rotating rod fixedly connected to the output end of the second motor, a second rotating rod rotatably connected to one end of the first rotating rod, a slider rotatably connected to one end of the second rotating rod, the slider slidingly connected inside the sliding groove, an air outlet fixedly connected to the bottom end of the slider, a blower fixedly installed on the top of the top plate, an air outlet pipe fixedly connected to the output end of the blower, and one end of the air outlet pipe fixedly connected to one side of the air outlet.

[0007] As a preferred embodiment of the above technical solution, the lifting structure includes a base frame, a support plate fixedly connected to the inner wall of the base frame, a first motor fixedly mounted on the top of the support plate, a first rotating column fixedly connected to the output end of the first motor, a rotating disk fixedly connected to the bottom end of the first rotating column, a ball fixedly connected to the top of the rotating disk, a second rotating column fixedly connected to the top of the ball, a top plate fixedly connected to the top of the second rotating column, a plurality of ejector pins fixedly connected to the top of the top plate, a spring fixedly connected to the bottom of the top plate, one end of the spring fixedly connected to the top of the support plate, the spring being sleeved outside the second rotating column, a base plate fixedly connected to the inner wall of the base frame, and a mold box disposed inside the base plate.

[0008] As a preferred embodiment of the above technical solution, the load-bearing structure includes two side plates, the top plate is fixedly connected to the top of the two side plates, and the two side plates are fixedly connected to the top sides of the bottom frame.

[0009] As a preferred embodiment of the above technical solution, the air outlet pipe runs through the interior of the top plate and is located at the bottom of the top plate.

[0010] As a preferred embodiment of the above technical solution, the rotating disk is rotatably connected to the bottom end of the inner wall of the base frame, and the rolling ball is slidably connected to the top of the rotating disk.

[0011] As a preferred embodiment of the above technical solution, the first rotating column end penetrates through the inner wall of the support plate, and the second rotating column is slidably connected inside the support plate.

[0012] As a preferred embodiment of the above technical solution, a plurality of ejector pins penetrate the bottom of the base plate, and the air outlet is located at the top of the mold box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model is equipped with a blower mechanism. Through the reciprocating blower structure driven by a motor, the blower head can perform scanning blower on the mold surface, which completely changes the traditional fixed-point cooling mode. This dynamic cooling method greatly improves the heat exchange efficiency between the airflow and the mold, shortens the cooling time, and effectively avoids product deformation caused by uneven cooling.

[0015] Based on the above-mentioned beneficial effects, this utility model is equipped with a lifting mechanism. Through the unique design of the lifting structure using a motor drive combined with a rotating disk and a ball, the rotational motion is transformed into a smooth linear lifting motion. The ejection force is gentle and uniform, reducing the impact on the product and mold during the ejection process and reducing the risk of product damage. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-5 As shown, this utility model provides a technical solution: an industrial connector injection molding device, including a support structure 1 for supporting the internal structure, a lifting structure 2 for lifting the connector mold inside the support structure 1, and a blowing structure 3 for cooling the mold on the top of the support structure 1.

[0024] The load-bearing structure 1 serves as the overall frame, ensuring the rigidity and stability of the equipment during operation; the internal lifting structure 2 is responsible for the precise ejection and demolding of the product; and the top blowing structure 3 is responsible for the efficient and uniform forced cooling of the high-temperature mold.

[0025] The blower structure 3 includes a top plate 12, a horizontal frame 31 fixedly connected to the top of the top plate 12, a sliding groove 37 opened inside the horizontal frame 31, a support frame 33 fixedly connected to the top of the top plate 12, a second motor 34 fixedly installed on the top of the support frame 33, a first rotating rod 35 fixedly connected to the output end of the second motor 34, a second rotating rod 310 rotatably connected to one end of the first rotating rod 35, a slider 32 rotatably connected to one end of the second rotating rod 310, the slider 32 slidably connected inside the sliding groove 37, an air outlet 39 fixedly connected to the bottom end of the slider 32, a blower 36 fixedly installed on the top of the top plate 12, an air outlet pipe 38 fixedly connected to the output end of the blower 36, and one end of the air outlet pipe 38 fixedly connected to one side of the air outlet 39.

[0026] The combination of forced convection and scanning air supply greatly enhances the heat exchange efficiency between the mold and the cooling air, thereby effectively shortening the cooling time. On the other hand, uniform heat dissipation avoids local overcooling or insufficient cooling of the mold, fundamentally reducing quality defects such as warping and deformation of injection molded products caused by uneven thermal stress.

[0027] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the lifting structure 2 includes a base frame 13, a support plate 28 fixedly connected to the inner wall of the base frame 13, a first motor 24 fixedly installed on the top of the support plate 28, a first rotating column 25 fixedly connected to the output end of the first motor 24, a rotating disk 26 fixedly connected to the bottom end of the first rotating column 25, a ball 27 fixedly connected to the top of the rotating disk 26, a second rotating column 29 fixedly connected to the top of the ball 27, a top plate 211 fixedly connected to the top of the second rotating column 29, a plurality of ejector pins 23 fixedly connected to the top of the top plate 211, a spring 210 fixedly connected to the bottom of the top plate 211, one end of the spring 210 fixedly connected to the top of the support plate 28, and the spring 210 sleeved on the outside of the second rotating column 29. A base plate 21 is fixedly connected to the inner wall of the base frame 13, and a mold box 22 is provided inside the base plate 21.

[0028] The ejection force is gentler and more uniform, effectively reducing the impact on the precision connector product and its mold during ejection. This greatly reduces the risk of surface scratches, whitening, or deformation. Simultaneously, spring 210 not only provides the necessary preload for the ejection system, but also, when the first motor 24 reverses, the elastic potential energy stored in spring 210 can quickly and reliably assist the entire ejection mechanism in resetting. This ensures accurate return to the initial position after each ejection cycle, avoiding the risk of reset jamming, thus guaranteeing the continuous stability of equipment operation and a long service life.

[0029] As one implementation method in this embodiment, please refer to Figures 1-5 As shown, the load-bearing structure 1 includes two side plates 11, a top plate 12 is fixedly connected to the top of the two side plates 11, and the two side plates 11 are fixedly connected to the top sides of the bottom frame 13.

[0030] The beneficial effect of this structure is that it provides a stable mounting platform for the internal precision lifting structure 2 and the top blowing structure 3, effectively absorbing the vibration generated during equipment operation, ensuring the accuracy of the relative positions between the ejector pin 23 and the mold, as well as between the air outlet 39 and the mold box 22, laying a solid foundation for the high-precision and high-stability operation of the entire device.

[0031] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the air outlet 39 extends through the interior of the top plate 12, and the air outlet duct 38 is located at the bottom of the top plate 12.

[0032] It minimizes the distance between the air outlet 39 and the mold surface, reduces the pressure and air volume loss of the airflow during the delivery process, and ensures that the cooling airflow can act directly on the mold surface with the highest efficiency.

[0033] As one implementation method in this embodiment, please refer to Figure 1 and Figures 4-5 As shown, the rotating disk 26 is rotatably connected to the bottom end of the inner wall of the base frame 13, and the rolling ball 27 is slidably connected to the top of the rotating disk 26.

[0034] As a highly efficient intermediate transmission component, the ball 27 can smoothly convert the rotational motion of the rotating disk 26 into the linear motion of the second rotating column 29 with extremely low frictional resistance. It not only has high transmission efficiency but also low wear, ensuring the reliability and durability of the lifting structure 2 during long-term operation.

[0035] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the first rotating column 25 extends through the inner wall of the support plate 28, and the second rotating column 29 is slidably connected inside the support plate 28.

[0036] The support plate 28 provides additional radial support for the first rotating column 25 to prevent it from bending under high torque; at the same time, it precisely constrains the movement trajectory of the second rotating column 29.

[0037] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, multiple ejector pins 23 extend through the bottom of the base plate 21, and the air outlet 39 is located at the top of the mold box 22.

[0038] The mold features a highly efficient dynamic cooling zone above and a stable ejection zone below. Together, they form a complete, efficient, and automated injection molding post-processing solution.

[0039] Working principle: The operator or control system starts the blower 36 and the second motor 34. The blower 36 generates cooling airflow, which is delivered to the air outlet 39 through the air outlet pipe 38. The second motor 34 starts, driving the first rotating rod 35 to rotate. The first rotating rod 35 pushes the slider 32 through the second rotating rod 310. The slider 32 moves horizontally and reciprocally in the groove 37 of the horizontal frame 31. The air outlet 39, which is fixedly connected to the bottom of the slider 32, also moves left and right along with it. During the movement, the air outlet 39 continuously blows air to cool the entire surface of the mold in the mold box 22 below.

[0040] The first motor 24 is started, causing the first rotating column 25 and the rotating disk 26 to rotate together. The ball 27 is fixed on the rotating disk 26, but it does not roll on top of the rotating disk 26; instead, it rotates with the rotating disk 26. Since the ball 27 is a sphere, its rotation drives the second rotating column 29, which is fixed to it, to move upward. The second rotating column 29 pushes the top plate 211 upward, and the top plate 211 drives multiple ejector pins 23 to move upward synchronously. The ejector pins 23 pass through the base plate 21 and precisely press against the bottom of the mold, thereby pushing the formed product out of the mold cavity.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
