Description

A battery cover injection mold Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically a battery cover injection mold. Background Technology

[0002] Plastic molds are tools used in the plastics processing industry in conjunction with plastic molding machines to give plastic products a complete shape and precise dimensions. Due to the wide variety of plastics and processing methods, as well as the varying complexity of plastic molding machines and plastic products, plastic molds also come in a wide variety of types and structures.

[0003] In the prior art, such as the new energy battery cover injection mold with good glue injection effect proposed in patent application number "CN202323010931.3", the upper mold base plate is provided with a second through hole connected to the positioning post mold closing groove and the first through hole. The lower mold is provided below the upper mold, and the base is provided below the lower mold. This structure is not only simple and convenient for glue injection, but also the glue injection method will not leave sprue, material head and ejector pin marks on the power battery cover, so that the appearance is neat and beautiful, and there is no glue residue.

[0004] However, in the aforementioned patent applications, battery cover plates are produced using injection molds. After cooling and molding, demolding is generally achieved by simply moving the upper mold upward with a single cylinder. This cannot ensure that all parts of the molded cover plate can be successfully demolded, thus affecting the production efficiency of battery cover plates. Summary of the Invention

[0005] The purpose of this invention is to provide a battery cover injection mold to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A battery cover injection mold includes an upper mold and a lower mold. A connecting plate is fixedly installed on the upper surface of the upper mold, a top plate is fixedly installed on the upper surface of the connecting plate, and a nozzle is fixedly installed on the upper surface of the top plate. Connecting frames are fixedly installed on both outer side walls of the upper mold. Two auxiliary mechanisms are provided on both outer side walls of the lower mold, and a straightening mechanism is provided on both outer side walls of the lower mold.

[0008] The auxiliary mechanism includes a fixed frame, which is fixedly installed on the outer side wall of the lower mold. A limit frame is fixedly installed on the inner wall of the fixed frame. A sliding plate is slidably connected inside the fixed frame. A vertical plate is inserted into the upper surface of the fixed frame. An inclined push rod is inserted into the limit frame.

[0009] Preferably, the bottom end of the vertical plate is fixedly connected to the connecting plate, and the outer wall of the inclined push rod is rotatably connected to a connecting shaft near the bottom surface of the limiting frame.

[0010] Preferably, the inclined push rod is fitted with a fixed sleeve, and the fixed sleeve is fixedly connected to the fixed frame.

[0011] Preferably, a sliding rod is fixedly installed on the upper surface of the inclined push rod, and the sliding rod fits into the interior of the connecting frame.

[0012] Preferably, a mounting plate is fixedly connected to the upper surface of the fixed frame, and a gear two is rotatably connected to the outer wall of the mounting plate via a shaft. A motor is installed on the other outer wall of the mounting plate, and the output end of the motor is connected to the gear two. Several toothed grooves are opened on the outer wall of the vertical plate, and the several toothed grooves are meshed with the gear two.

[0013] Preferably, the correction mechanism includes a base plate and a clamping plate, wherein the base plate is fixedly installed on the outer side wall of the lower mold, and the clamping plate is movably installed on one side of the upper mold;

[0014] Mounting plates are fixedly installed on the upper surface of the base plate near both ends. Gear 1 is rotatably connected to the outer wall of each mounting plate via a shaft. Movable rods are rotatably connected to the other outer wall of each mounting plate via a shaft, and the movable rods are fixedly connected to gear 1 via shafts.

[0015] Preferably, one end of each of the two movable rods is fixedly connected to the clamping plate, and an L-shaped connecting rod is fixedly connected to the outer wall of the slide plate. One end of the L-shaped connecting rod is fixedly connected to a rack, and the rack and gear are meshed with each other.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, during mold opening, the motor on the mounting plate drives the gear two to rotate simultaneously. This, in conjunction with the various toothed grooves, moves the vertical plate upwards, thereby moving the sliding plate upwards. The limiting frame and the fixed sleeve follow suit, allowing the inclined push rod to move upwards as a whole, assisting in pushing the connecting frame upwards. This pushes the upper mold at an angle. Simultaneously, the bottom end of the inclined push rod slides along the bottom of the sliding plate, moves along the inside of the limiting frame, and slides along the inside of the fixed sleeve. The upper end of the inclined push rod slides along the inside of the connecting frame via a sliding rod, allowing for upward pushing of the connecting frame while simultaneously moving laterally, changing the pushing contact position, and better pushing the upper mold. This makes demolding smoother. Auxiliary mechanisms are provided on both sides to assist in demolding from both sides of the injection mold. This bidirectional synchronous upward pushing ensures that the molding material is smoothly demolded from the injection mold, avoiding demolding failure caused by a single lifting method.

[0018] 2. In this utility model, during demolding, the vertical plate moves upward, and the L-shaped connecting rod moves upward with the vertical plate, which can drive the first gear and the rack to move upward, drive the first gear to rotate, thereby driving the movable rod to rotate, and drive the clamping plate away from the upper mold and the lower mold, releasing the clamping limit on the upper mold and the lower mold. Similarly, when the upper mold moves downward to reset, the rack moves downward, cooperating with the first gear, so that the clamping plate is close to the outer wall of the upper mold and the lower mold. Similarly, the other clamping plate rotates at the same time to be close to the other outer wall of the upper mold and the lower mold, clamping and limiting the position between the upper mold and the lower mold, further correcting the position between the upper mold and the lower mold, avoiding slack, and affecting the injection molding effect.

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A battery cover injection mold, as shown in Figures 1-4, includes an upper mold 3 and a lower mold 4. A connecting plate 2 is fixedly installed on the upper surface of the upper mold 3, a top plate 1 is fixedly installed on the upper surface of the connecting plate 2, and a nozzle 5 is fixedly installed on the upper surface of the top plate 1. Connecting frames 7 are fixedly installed on both outer walls of the upper mold 3. Two auxiliary mechanisms are provided on both outer walls of the lower mold 4, and a straightening mechanism is provided on both outer walls of the lower mold 4. The auxiliary mechanisms include a fixed frame 6, which is fixedly installed on the outer wall of the lower mold 4. A limit frame 13 is fixedly installed on the inner wall of the fixed frame 6. A sliding plate 12 is slidably connected inside the fixed frame 6. A vertical plate 11 is inserted into the upper surface of the fixed frame 6, and a slanted push rod 14 is inserted into the limit frame 13.

[0028] The bottom end of the vertical plate 11 is fixedly connected to the connecting plate 2. The outer wall of the inclined push rod 14 is rotatably connected to the connecting shaft 17 near the bottom surface of the limiting frame 13. The inclined push rod 14 is fitted with a fixed sleeve 16, which is fixedly connected to the fixed frame 6. The upper surface of the inclined push rod 14 is fixedly installed with a slide rod 15, which fits into the inside of the connecting frame 7. The connecting shaft 17 moves with the inclined push rod 14 and moves along the bottom surface of the limiting frame 13, which can limit the movement position of the inclined push rod 14.

[0029] A mounting plate is fixedly connected to the upper surface of the fixed frame 6. Gear 21 is rotatably connected to the outer wall of the mounting plate via a shaft. A motor is installed on the other outer wall of the mounting plate, and the output end of the motor is connected to gear 21. Several toothed grooves are opened on the outer wall of the vertical plate 11, and several toothed grooves are meshed with gear 21. The motor model is MDM-DE40DN0H.

[0030] In use, raw material is injected into the nozzle 5 and added to the injection mold, so that the raw material cools and solidifies in the upper mold 3 and lower mold 4 to produce a battery cover. After molding, when the mold needs to be opened, the top plate 1 and the connecting plate 2 can be moved upward, which will drive the upper mold 3 to move upward. The top plate 1 is connected to an external cylinder, and the upper mold 3 can be moved upward by the external cylinder to demold. This is existing technology and will not be described in detail here.

[0031] During mold opening, the motor on the mounting plate drives gear 21 to rotate, which, in conjunction with the various tooth grooves, moves the vertical plate 11 upward, thereby moving the slide plate 12 upward. The limiting frame 13 and the fixed sleeve 16 follow suit, allowing the inclined push rod 14 to move upward as a whole, assisting in pushing the connecting frame 7 upward, thus pushing the upper mold 3 at an angle. At the same time, the bottom end of the inclined push rod 14 slides along the bottom end of the slide plate 12, and the bottom of the inclined push rod 14 moves along the inside of the limiting frame 13 and slides along the inside of the fixed sleeve 16. The upper end of the inclined push rod 14 slides along the inside of the connecting frame 7 through the slide rod 15, which can push the connecting frame 7 upward while moving laterally, changing the pushing contact position, and better pushing the upper mold 3, making demolding smoother and ensuring that all parts of the molded cover can be demolded smoothly. Auxiliary mechanisms are set on both sides to assist demolding on both sides of the injection mold, pushing upward in both directions simultaneously to ensure that the molding material is demolded smoothly from the injection mold, avoiding demolding failure caused by a single lifting method.

[0032] As shown in Figures 1-4, the correction mechanism includes a base plate 9 and a clamping plate 8. The base plate 9 is fixedly installed on the outer wall of the lower mold 4, and the clamping plate 8 is movably installed on one side of the upper mold 3. Mounting plates are fixedly installed on the upper surface of the base plate 9 near both ends. Gear 18 is rotatably connected to the outer wall of both mounting plates through a shaft. Movable rod 10 is rotatably connected to the other outer wall of both mounting plates through a shaft, and the movable rod 10 is fixedly connected to gear 18 through a shaft.

[0033] One end of each of the two movable rods 10 is fixedly connected to the clamping plate 8. An L-shaped connecting rod 20 is fixedly connected to the outer wall of the slide plate 12. One end of the L-shaped connecting rod 20 is fixedly connected to a rack 19, and the rack 19 and the gear 18 are meshed with each other.

[0034] Specifically, during demolding, the vertical plate 11 moves upward, and the L-shaped connecting rod 20 moves upward with the vertical plate 11. This can drive the gear 18 and rack 19 to move upward, causing the gear 18 to rotate, which in turn drives the movable rod 10 to rotate. This causes the clamping plate 8 to move away from the upper mold 3 and lower mold 4, releasing the clamping and limiting effect on the upper mold 3 and lower mold 4. Similarly, when the upper mold 3 moves downward to reset, the rack 19 moves downward, which can drive the gear 18 to rotate in the opposite direction, thereby driving the movable rod 10 to rotate. This makes the clamping plate 8 tightly adhere to the outer wall of the upper mold 3 and lower mold 4. Similarly, the other clamping plate 8 rotates at the same time to tightly adhere to the other outer wall of the upper mold 3 and lower mold 4, clamping and limiting the position between the upper mold 3 and lower mold 4, further correcting the position between the upper mold 3 and lower mold 4, avoiding caking, and affecting the injection molding effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
