Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a core-pulling mold for the top block of an infusion set. Background Technology

[0002] Core-pulling molds are molds that achieve lateral parting and core pulling through a core-pulling mechanism. Their core structure includes a core and a core-pulling device (such as a guide post or hydraulic cylinder), which allows the core to retract during mold opening, facilitating the removal of plastic parts with side recesses or side holes. They offer advantages such as high production efficiency and stable molding quality, and are widely used in the molding of complex parts in the automotive, electronics, and home appliance industries.

[0003] In the existing technology, the core-pulling mold for the top block of the infusion set mostly relies on manual demolding. Operators need to manually intervene in the resetting of the top block and the extraction of the core, which is time-consuming, labor-intensive, and has low production efficiency. Furthermore, manual operation makes it difficult to accurately control the demolding sequence and force, which can easily lead to defects such as deformation and tearing of the plastic parts due to uneven stress.

[0004] To address the above problems, a core-pulling mold for the top block of an infusion set is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a core-pulling mold for the top block of an infusion set, which aims to improve the existing technology where the core-pulling mold for the top block of an infusion set mostly relies on manual assistance for demolding. It requires operators to manually intervene in the resetting of the top block and the extraction of the core, which is time-consuming, labor-intensive, and has low production efficiency. Furthermore, manual operation makes it difficult to accurately control the demolding sequence and force, which can easily lead to defects such as deformation and tearing of the plastic parts due to uneven stress.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an infusion set top block core-pulling mold, comprising a lower mold, a plurality of sliding rods fixedly connected to the top of the lower mold, a sliding plate slidably connected to the outer side of the sliding rods, an injection port and an injection channel inside the sliding plate, a plurality of upper molds for the infusion set fixedly connected to the bottom of the sliding plate, a plurality of cavities inside the lower mold, a heat dissipation component inside the cavity, and an ejection component inside the lower mold;

[0007] The ejection assembly includes a motor, an ejection frame, and two connecting rods. The ejection frame is slidably connected to the inside of the lower mold on its outer side, and the connecting rods are rotatably connected to the inside of the lower mold on their outer side. The motor is fixedly connected to the inner wall of the lower mold on its outer side. A rotating rod is fixedly connected to the output end of the motor. Two bevel gears are fixedly connected to the outer side of the rotating rod, and two bevel gears are fixedly connected to the outer side of the connecting rod. Multiple cams are fixedly connected to the outer side of the connecting rod. The two bevel gears mesh with the first bevel gears. Multiple springs are fixedly connected to the top of the ejection frame, and multiple ejector blocks are fixedly connected to the top of the ejection frame.

[0008] As a further description of the above technical solution:

[0009] The heat dissipation assembly includes a water tank, which is fixedly connected to the outside of the lower mold. Heat dissipation fins are fixedly connected to the outside of the water tank, and a circulating water pipe is fixedly connected to the outside of the water tank. A circulating pump is installed on the outside of the circulating water pipe.

[0010] As a further description of the above technical solution:

[0011] The outer side of the top block is slidably connected to the inside of the lower mold.

[0012] As a further description of the above technical solution:

[0013] The end of the spring away from the ejector is fixedly connected to the inner wall of the lower mold, and the outer side of the rotating rod is rotatably connected to the inside of the lower mold.

[0014] As a further description of the above technical solution:

[0015] A water inlet is fixedly connected to the top of the water tank.

[0016] As a further description of the above technical solution:

[0017] The circulating water pipe is fixedly connected to the inside of the lower mold on the outside.

[0018] As a further description of the above technical solution:

[0019] The injection port, the injection channel, and the mold on the infusion set are connected.

[0020] As a further description of the above technical solution:

[0021] The cam and the ejector frame are always in contact with each other.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a motor drives a rotating rod to rotate, and a bevel gear one on the rotating rod meshes with a bevel gear two on the connecting rod to drive the connecting rod to rotate. The cam on the outside of the connecting rod rotates accordingly. The cam and the ejector frame are always in contact with each other. As the cam rotates, the ejector frame slides up and down along the inside of the lower mold with the assistance of a spring. The top block at the top of the ejector frame pushes the molded infusion set out of the cavity, realizing automatic and efficient demolding. Compared with the traditional manual demolding method, it greatly improves production efficiency and shortens the production cycle.

[0024] 2. In this utility model, the water in the tank is driven to flow in the circulating water pipe by the start of the circulating pump. The circulating water pipe is arranged inside the lower mold. During the flow of water, the heat in the mold is carried away. At the same time, the heat dissipation fins on the outside of the water tank increase the heat dissipation area and accelerate the heat dissipation. This achieves continuous and stable heat dissipation of the mold and avoids problems such as poor raw material molding and product deformation caused by excessive mold temperature. This ensures the stability and consistency of the infusion set product quality. Attached Figure Description

[0035] Reference Figures 1-3 The heat dissipation component includes a water tank 8, which is fixedly connected to the outside of the lower mold 6. Heat dissipation fins 10 are fixedly connected to the outside of the water tank 8, and a circulating water pipe 11 is fixedly connected to the outside of the water tank 8. A circulating pump 12 is installed on the outside of the circulating water pipe 11.

[0036] Specifically, the water tank 8 is used to store coolant; the heat dissipation fins 10 are used to increase the heat dissipation area and accelerate the heat dissipation of the coolant in the water tank 8; the circulating water pipe 11 is used to form a coolant circulation channel, connecting the water tank 8 with the interior of the lower mold 6; the circulating pump 12 is used to drive the coolant to flow in the circulating water pipe 11, carrying away the heat generated in the cavity 7 of the lower mold 6 during the injection molding process, thereby achieving effective cooling of the mold.

[0037] Reference Figures 1-4The top block 20 is slidably connected to the inside of the lower mold 6 on the outside. The end of the spring 21 away from the ejector 19 is fixedly connected to the inner wall of the lower mold 6. The outer side of the rotating rod 14 is rotatably connected to the inside of the lower mold 6. The top of the water tank 8 is fixedly connected to the water inlet 9. The outer side of the circulating water pipe 11 is fixedly connected to the inside of the lower mold 6. The injection port 3, the injection channel 4 and the upper mold 5 of the infusion set are connected. The cam 18 and the ejector 19 are always in contact with each other.

[0038] Specifically, the top block 20 is used to eject the molded infusion set from the cavity 7 of the lower mold 6 under the drive of the ejector frame 19; the spring 21 is used to provide a restoring force after the ejector frame 19 completes the ejection action; the rotating rod 14 is used to drive the connecting rod 16 to rotate through the bevel gear 15 and bevel gear 17 under the drive of the motor 13; the water inlet 9 is used to add coolant to the water tank 8; the circulating water pipe 11 is used to make the coolant circulate between the water tank 8 and the lower mold 6 to achieve heat dissipation; the injection port 3, the injection channel 4 and the upper mold 5 of the infusion set are connected to allow the raw material to flow smoothly into the cavity 7 to complete the injection molding; the cam 18 is used to push the ejector frame 19 to achieve the ejection action by abutting against it.

[0039] Working principle: When using the core-pulling mold for the top block of the infusion set, first place the slide plate 2 in a suitable position through the slide rod 1, inject the raw material through the injection port 3, and the raw material enters the upper mold 5 of the infusion set through the injection channel 4. Then the slide plate 2 slides down, so that the upper mold 5 of the infusion set and the cavity 7 of the lower mold 6 cooperate to complete the mold closing.

[0040] After the mold is closed, the circulation pump 12 starts, which drives the water in the water tank 8 to flow in the circulation water pipe 11. The water carries away the heat through the interior of the lower mold 6. At the same time, the heat dissipation fins 10 on the outside of the water tank 8 accelerate the heat dissipation, achieve effective heat dissipation of the mold, and ensure the mold temperature is stable during the injection molding process.

[0041] After injection molding is completed, motor 13 starts, and the rotating rod 14 at its output end drives bevel gear 15 to rotate. Through the meshing bevel gear 17, connecting rod 16 rotates, and cam 18 on connecting rod 16 rotates accordingly. Since cam 18 and ejector 19 are always in contact with each other, as cam 18 rotates, ejector 19 slides up and down inside the lower mold 6 with the assistance of spring 21. The top block 20 at the top of ejector 19 pushes the molded infusion set out of cavity 7, completing demolding.
