Description

Technical Field

[0001] This utility model relates to the technical field of injection molding machines, specifically to an injection molding machine for insulating caps. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. Generally, an insulating cap is added between the lithium battery cell and the outer casing to facilitate the connection of the positive and negative electrodes, providing insulation and improving battery safety to some extent.

[0003] The current method of cooling injection molded parts is basically to allow them to cool naturally. While this natural cooling can meet certain usage requirements, it also has significant drawbacks: it is cumbersome to operate, inefficient, labor-intensive, and has high labor costs. The cooling speed is slow and the cycle is long. Furthermore, the ambient temperature changes during the cooling process, which can affect product quality, resulting in poor product quality that fails to meet usage requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an injection molding machine for insulating caps to solve the aforementioned defects caused by the prior art.

[0005] An injection molding machine for insulating caps includes a base, a molten material tank, and a cooling water tank. An upper mold is provided on the outer side of the base, and an electric cylinder output terminal is connected to the top of the upper mold. A lower mold is connected to the outer side of the base, and an electric cylinder is connected through the outer side of the base. An injection molding mechanism is provided on one side of the base. The injection molding mechanism heats and melts the injected material, and then injects the molten material into the upper and lower molds to form an injection cavity. A cooling mechanism is provided directly below the molten material tank. The cooling mechanism circulates and cools the material through a circulating liquid, thereby cooling the material during the feeding process.

[0006] Preferably, the injection molding mechanism includes a servo motor, a molten material tank, a mixing rod, and a solenoid valve. The servo motor is installed at the top of the molten material tank, and the output end of the servo motor is connected to the mixing rod, which is located inside the molten material tank. The bottom end of the molten material tank is connected to the output end of the solenoid valve, and the molten material tank is installed on one side of the base.

[0007] Preferably, the molten material tank is connected to the lower mold injection end via a solenoid valve located at the bottom.

[0008] Preferably, the cooling mechanism includes a cooling water tank, a liquid injection hose, a spiral blade, a conical tooth, a mold base, and a circulating water cavity. One end of the cooling water tank is connected to one end of the liquid injection hose. The interior of the cooling water tank is provided with a spiral blade. One side of the spiral blade is connected with a conical tooth. One set of the conical teeth is installed inside the cooling water tank, and another set of the conical teeth is installed at the bottom end of the mixing rod. The cooling water tank is located below the molten material tank body, and the mold base is installed below the lower mold. The interior of the lower mold has a circulating water cavity.

[0009] Preferably, the servo motor is connected to the outer side of the bevel gear via a mixing rod connected to its output end.

[0010] Preferably, the spiral blade is connected to another set of conical teeth via conical teeth connected on one side.

[0011] Preferably, the lower mold is connected to the other end of the injection hose through an internal circulating water cavity.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. During use, on the one hand, the mixing rod is driven by the servo motor to mix and heat-treat the material, so that cooling and molding and rapid material flow can be completed at the same time as injection molding, thereby improving the processing efficiency of the extruder. At the same time, the structure is simple, easy to maintain, convenient to control and operate, and has a good cost-effectiveness ratio. On the other hand, the bevel gear is used for transmission to control the flow speed of the material and to control the injection speed and liquid injection speed synchronously.

[0014] 2. The mixing rod and conical teeth are driven to rotate by a servo motor. The conical teeth drive the spiral blades on one side to rotate, and the spiral blades drive the liquid to rotate and be injected. The liquid is continuously injected into the interior of the circulating water chamber, thereby reducing the temperature of the lower mold and improving the stability of the temperature control at the bottom of the lower mold.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, the insulating cap injection molding machine includes a base 1, a molten material tank 7, and a cooling water tank 8. An upper mold 2 is provided on the outer side of the base 1, and the top of the upper mold 2 is connected to the output end of an electric cylinder 4. A lower mold 3 is connected to the outer side of the base 1, and the electric cylinder 4 is connected through the outer side of the base 1. An injection molding mechanism 5 is provided on one side of the base 1. The injection molding mechanism 5 heats and melts the injected material, and then injects the melted material into the upper mold 2 and the lower mold 3 to form an injection cavity. A cooling mechanism 10 is provided directly below the molten material tank 7. The cooling mechanism 10 circulates and cools the material through a circulating liquid, thereby cooling the material during the feeding process.

[0024] In this embodiment, the injection molding mechanism 5 includes a servo motor 6, a molten material tank 7, a mixing rod 13, and a solenoid valve 14. The servo motor 6 is installed at the top of the molten material tank 7, and the output end of the servo motor 6 is connected to the mixing rod 13. The mixing rod 13 is disposed inside the molten material tank 7, and the bottom end of the molten material tank 7 is connected to the output end of the solenoid valve 14. The molten material tank 7 is installed on one side of the base 1.

[0025] In this embodiment, the molten material tank 7 is connected to the injection end of the lower mold 3 through a solenoid valve 14 at the bottom. The molten material is directly injected into the upper mold 2 and the lower mold 3 through the solenoid valve 14 to form the injection cavity, and the insulating cover is cooled and formed.

[0026] In this embodiment, the cooling mechanism 10 includes a cooling water tank 8, a liquid injection hose 9, a spiral blade 11, a conical tooth 12, a mold base 15, and a circulating water chamber 16. One end of the cooling water tank 8 is connected to one end of the liquid injection hose 9. The spiral blade 11 is provided inside the cooling water tank 8. One side of the spiral blade 11 is connected to a conical tooth 12. One set of the conical teeth 12 is installed inside the cooling water tank 8, and another set of the conical teeth 12 is installed at the bottom end of the mixing rod 13. The cooling water tank 8 is located below the molten material tank 7. The mold base 15 is installed below the lower mold 3. The lower mold 3 has a circulating water chamber 16 inside.

[0027] In this embodiment, the servo motor 6 is connected to the outside of the bevel gear 12 via the mixing rod 13 connected to the output end. The servo motor 6 drives the mixing rod 13 to rotate, thereby heating and melting the material.

[0028] In this embodiment, the spiral blade 11 is connected to another set of conical teeth 12 via a conical tooth 12 connected on one side, and the liquid injection speed is controlled by the transmission through the conical teeth 12.

[0029] In this embodiment, the lower mold 3 is connected to the other end of the injection hose 9 through an internally provided circulating water chamber 16. The injection and circulation of the liquid are carried out through the injection hose 9 to control the flow rate of the liquid.

[0030] In practical applications, this type of insulating cap injection molding machine includes the following tasks:

[0031] Step 1: The operator injects the material into the melting tank 7, heats the material by turning on the internal electric heating wire of the melting tank 7, and drives the mixing rod 13 to rotate by turning on the servo motor 6 to stir the material. After the material is heated, the solenoid valve 14 at the bottom is connected to the injection cavity of the lower mold 3. The electric cylinder 4 is turned on to drive the upper mold 2 to move vertically downward, so that the top of the upper mold 2 and the lower mold 3 are sealed.

[0032] Step 2: Then, cool water is injected into the interior of the cooling water tank 8. The injection hose 9 on one side of the cooling water tank 8 is connected to one side of the mold base 15. When the servo motor 6 drives the mixing rod 13 to rotate, the mixing rod 13 drives the bevel gear 12 to rotate, and the bevel gear 12 on one side and the spiral blade 11 to rotate, thereby accelerating the flow of liquid.

[0033] Step 3: When the solenoid valve 14 continuously injects material into the upper mold 2 and the lower mold 3, cooling water is injected into the circulating water chamber 16. The circulating water chamber 16 removes the heat from the bottom of the lower mold 3, and the liquid is returned to the cooling water tank 8 through the outlet on one side of the circulating water chamber 16, thereby completing the cooling water circulation and cooling.

[0034] Step 4: After the material is injected to the last part, the rotation speed of the servo motor 6 is controlled to control the rotation speed of the mixing rod 13 and the bevel gear 12. The rotation speed of the spiral blade 11 driven by the bevel gear 12 is reduced, thereby reducing the flow speed of the liquid. After the injection is completed, new material is added. After the cooling water is circulated by the spiral blade 11 for a period of time, the electric cylinder 4 is opened. The electric cylinder 4 drives the upper mold 2 to move upward, completing the separation of the upper mold 2 and the lower mold 3.

[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
