Description

Technical Field

[0001] The utility model relates to the field of lead-acid battery casings, in particular to an injection molding device for lead-acid battery casings. Background Technique

[0002] The casing of a storage battery is mainly made of metal or plastic, and its design aims to protect the internal structure of the storage battery, including the plate group and the electrolyte, from the influence of the external environment. This protection includes preventing external factors such as moisture, dust, and chemical substances from eroding and damaging the inside of the storage battery. In addition, the casing can effectively prevent electrolyte leakage and ensure the safety and stability of the storage battery.

[0003] After retrieval, an injection molding device for a storage battery casing with a rapid cooling structure disclosed in a Chinese patent with the publication number CN213766862U includes a recycling box and a water inlet pipe.

In this injection molding device for a storage battery casing with a rapid cooling structure, ice water is introduced into the water storage tank through the water inlet pipe, the valve is started, and the ice water in the water storage tank enters the condensing pipe through a diversion pipe. The condensing pipe is fixedly connected in the cavity in a spiral shape, increasing the contact area, thereby taking away more heat, so as to achieve the purpose of rapid cooling. After the cold water passes through the condensing pipe, it enters the recycling box for recycling.

[0004] Although the above-mentioned patent can cool the injection-molded casing and rapidly cool the injection mold during use, in the actual use process, since the lead-acid battery casing after injection molding is in close contact with the mold, the lead-acid battery mold is prone to jamming inside the mold, resulting in a slow speed when taking out the injection-molded parts of the lead-acid battery casing.

[0005] Therefore, we propose an injection molding device for lead-acid battery casings to solve the above problems. Content of the Utility Model

The top end of the electric push rod 302 is fixedly connected to the bottom surface of the lower mold 2. By closing the upper mold 1, the feed pipe 101 and the lower mold 2, injection molding of the lead-acid battery shell can be carried out.

[0027] The pushing structure of the pushing assembly 3 includes a control board 305. The upper surface of the control board 305 is fixedly connected to the telescopic end of the electric push rod 302. Two groups of ejector rods 306 are fixedly connected to the upper surface of the control board 305. A conduit 303 is sleeved on the outer surface of each ejector rod 306. The top end of each conduit 303 penetrates through the lower mold 2 and is communicated with the inner bottom wall of the groove 201. The top end of each ejector rod 306 extends into the groove 201. The top end of each ejector rod 306 is fixedly connected to an ejector block 304. By using the electric push rod 302, the pushing structure can be controlled to move up and down, so that the pushing structure can push out the injection molded parts. A sealing ring 307 is sleeved on the outer surface of each ejector rod 306. The bottom surfaces of the two groups of sealing rings 307 are respectively fixedly connected to the inner bottom walls of the two groups of grooves 201. By providing the sealing ring 307, the sealing performance between the groove 201 and the ejector rod 306 can be increased.

[0028] Furthermore, in order to facilitate the staff to repair the inside of the device, as shown in the attached Figure 1 and the attached Figure 2 and the attached Figure 3 shown, mounting seats 308 are fixedly connected to the left and right side surfaces of the housing 301. Mounting holes are opened on the upper surface of each mounting seat 308. By means of the mounting seats 308, the staff can easily disassemble the device, so as to facilitate the repair of the inside of the housing 301. Two groups of through grooves 309 are opened on the front and back of the housing 301. Through the through grooves 309, air can flow inside the housing 301, so that the heat inside the housing 301 can be dissipated to the outside.

[0029] Second Embodiment

[0030] As shown in the attached Figure 1 and the attached Figure 2 and the attached Figure 3As shown, the guiding component 4 includes two guiding sleeves 401 installed on the left and right sides of the lower mold 2. A guiding rod 402 is slidably connected to the inner wall of each guiding sleeve 401. The tops of the mutually approaching sides of the two groups of guiding rods 402 are fixedly connected to the left and right sides of the upper mold 1 respectively. Through the cooperation of the guiding rod 402 and the guiding sleeve 401, the upper mold 1 and the lower mold 2 can be more accurately closed, avoiding misalignment between the upper mold 1 and the lower mold 2.

[0031] Third Embodiment

[0032] As shown in the attached Figure 1 - Figure 2 - Figure 3 - Figure 4 As shown, the cooling component 5 includes a water inlet pipe 501 and a water outlet pipe 502 arranged on the left and right sides of the lower mold 2, and a drain pipe 503 arranged on the right side of the lower mold 2. The right end of the water inlet pipe 501 penetrates through the lower mold 2 and extends into the interior of the cavity 202. The left end of the water outlet pipe 502 penetrates through the lower mold 2 and extends into the interior of the cavity 202. Water enters the interior of the cavity 202 through the water inlet pipe 501, and the water flows on the inner wall of the cavity 202, and the water is discharged through the water outlet pipe 502. During the flow of the water, the lower mold 2 is cooled, thereby reducing the temperature of the injection molded part.

[0033] Furthermore, in order to prevent water from remaining inside the lower mold 2, as shown in the attached Figure 1 - Figure 2 - Figure 3 -

[0034] Working principle: When in use, install the device at a designated position, connect the water inlet pipe 501 to a water source, and connect the feed pipe 101 to a feeding mechanism. After the upper mold 1 and the lower mold 2 are closed, raw materials can be injected into the mold through the feed pipe 101. After the injection molding is completed, turn on the water source to allow water to enter the cavity 202 through the water inlet pipe 501. After the water flows inside the cavity 202, the temperature of the water rises, and at the same time, the hot water can be discharged through the water outlet pipe 502 to cool the injection molded part. Start the electric push rod 302 to contract the electric push rod 302 and push the ejector rod 306 to slide inside the conduit 303, so that the ejector block 304 pushes the injection molded part out, enabling the operator to take the injection molded part. After stopping use, rotate the sealing head 504 to open the drain pipe 503 and drain the remaining water inside the cavity 202.
