Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery casing shaping technology, and in particular to a shaping device for injection molding cooling of lead-acid battery casing. Background Technology

[0002] The battery casing plays multiple crucial roles in the battery. First, it secures and seals the internal electrochemical system, ensuring stable operation of the battery in various environments. Second, it protects the positive and negative electrodes, preventing external environmental and physical damage from affecting the battery, thus ensuring its normal operation. Therefore, lead-acid batteries are installed in their corresponding battery casings during use.

[0003] Most lead-acid battery casings are made of plastic. Therefore, the battery casings are produced by injection molding. The battery casings are taken out of the mold at a high temperature, so cooling is necessary. During the cooling process, the battery casings are prone to deformation due to shrinkage, which can lead to insufficient dimensional accuracy. This can hinder the subsequent installation of the battery body and affect the aesthetics and structural strength of the battery casing.

[0004] To address the aforementioned issues, a shaping device is proposed that can support and prevent deformation of the battery casing during the cooling process. Utility Model Content

[0005] The purpose of this utility model is to provide a shaping device for injection molding and cooling of lead-acid battery casings, so as to solve the problem mentioned in the background art that the existing lead-acid battery casings are prone to deformation due to cooling shrinkage after injection molding, resulting in insufficient dimensional accuracy of the battery casings, thereby affecting the aesthetics and structural strength of the battery casings.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaping device for injection molding cooling of lead-acid battery casing, comprising multiple support members and multiple support strips. A clamping groove is formed at the bottom of each support strip along its length. The support strip is sleeved onto the top of the side wall of the battery casing or the top of the battery casing partition wall via the clamping groove. The width of the clamping groove and the width of the side wall of the battery casing or the width of the battery casing partition wall are interference fit. A set of support members is connected between the adjacent sides of two support strips. Two pairs of support ribs are symmetrically provided on each support member. A set of support members is composed of several support members distributed along the length of the battery casing partition wall, connected sequentially. The foremost and last support members in a set of multiple support members have their farthest sides abutting against the front and rear inner sidewalls of the battery casing, respectively.

[0007] Preferably, the support member includes two pairs of fixed blocks arranged in a rectangular shape. Two pairs of longitudinal strips are symmetrically fixedly connected to the adjacent sides of the two pairs of fixed blocks, and two pairs of transverse strips are symmetrically fixedly connected to the adjacent sides of the two pairs of fixed blocks. Two guide rods are symmetrically and movably inserted between the adjacent sides of the two pairs of transverse strips and between the adjacent sides of the two pairs of longitudinal strips. The support member also includes two pairs of filler strips. Two slots are symmetrically formed on the adjacent sides of each pair of filler strips. The two pairs of filler strips are symmetrically engaged with the outer circumference of the two pairs of guide rods through the slots. The two pairs of filler strips are respectively located between the adjacent sides of the two pairs of longitudinal strips and between the adjacent sides of the two pairs of transverse strips. The sides of the filler strips near the two adjacent fixed blocks are respectively abutted against the sides of the adjacent longitudinal strips or the adjacent transverse strips. A longitudinal spacing adjustment component for adjusting the distance between the two pairs of longitudinal strips and a transverse spacing adjustment component for adjusting the distance between the two pairs of longitudinal strips are provided between them. The length of the filler strip can be cut according to the spacing between the adjacent sides of the two pairs of longitudinal strips or the adjacent sides of the two pairs of transverse strips after adjustment. The opposite sides of the two pairs of transverse strips are slidably connected to the two adjacent support strips through the connecting component. The advantage of this setting is that the spacing between the two pairs of transverse strips and the two pairs of longitudinal strips can be adjusted by the longitudinal spacing adjustment component and the transverse spacing adjustment component, respectively. In addition, with the two pairs of filler strips cut according to the spacing between the adjacent sides of the two pairs of longitudinal strips or the adjacent sides of the two pairs of transverse strips after adjustment, the support can adjust the spacing between the two pairs of longitudinal strips and the spacing between the two pairs of transverse strips according to the actual width of the battery case to be shaped and supported and the spacing between the two adjacent battery case partitions in the battery case. Thus, the shaping device can be used to shape and support battery cases of various sizes, improving the applicability and practicality of the shaping device.

[0008] Preferably, the longitudinal spacing adjustment assembly includes two symmetrically distributed connecting plates, with a bidirectional screw threaded between the two connecting plates. The left and right ends of the bidirectional screw pass through the opposite sides of the two connecting plates. Two round rods are symmetrically and movably inserted into the opposite sides of the two connecting plates, with the left and right ends of the two round rods passing through the opposite sides of the two connecting plates. A knob is fixedly sleeved at the middle position of the bidirectional screw.

[0009] Preferably, the lateral spacing adjustment assembly includes two pairs of mounting cavities symmetrically opened on the opposite sides of the two connecting plates. The bottom of the two pairs of supporting ribs at their adjacent ends are symmetrically rotatably connected to the bottom wall of the mounting cavity via two pairs of first rotating shafts and two pairs of torsion springs. The lateral spacing adjustment assembly also includes two pairs of T-shaped grooves symmetrically opened on the opposite sides of the two pairs of longitudinal bars. Two pairs of T-shaped blocks are symmetrically slidably connected in the two pairs of T-shaped grooves. The opposite ends of the two pairs of supporting ribs are symmetrically hinged to the opposite sides of the two pairs of T-shaped blocks. The lateral spacing adjustment assembly also includes two clamping mechanisms symmetrically connected to the two connecting plates. The clamping mechanisms are used to clamp the two pairs of supporting ribs.

[0010] Preferably, the pressing mechanism includes two rectangular cavities symmetrically opened on the top of the two connecting plates. Two pairs of insert rods are symmetrically and movably inserted into the bottom walls of the two rectangular cavities. The bottom ends of the two pairs of insert rods penetrate the inner bottom walls of the two rectangular cavities and extend into the interior of the two pairs of mounting cavities. Two pairs of pressure plates are symmetrically and fixedly connected to the bottom ends of the two pairs of insert rods. The two pairs of pressure plates are located directly above the two pairs of support ribs and can press tightly against the top surface of the support ribs. Two rectangular plates are symmetrically and fixedly connected between the top ends of the two pairs of insert rods. Two pairs of elastic elements are symmetrically and fixedly connected between the bottom of the two rectangular plates and the inner bottom walls of the two rectangular cavities. The pressing mechanism also includes two limiting units symmetrically connected to the two connecting plates. The limiting units are used to limit and press the rectangular plates into the two rectangular cavities.

[0011] Preferably, the limiting unit includes two pairs of limiting blocks symmetrically fixedly connected to the top of the two connecting plates. Two pairs of limiting grooves are symmetrically opened on the opposite sides of the two pairs of limiting blocks. Two limiting plates are symmetrically slidably connected to the top of the two connecting plates. The two limiting plates can slide towards each other along the length of the longitudinal strip. The opposite ends of the two limiting plates can be slidably inserted into the two pairs of limiting grooves respectively. The advantage of this design is that the operator only needs to press down on the two limiting plates with both thumbs until the two rectangular plates are inserted into the two rectangular cavities respectively. Then, push the two limiting plates in opposite directions until the two limiting plates are moved out of the two pairs of limiting grooves. At this time, the limiting plates are released, and the pressure plate moves upward under the elastic force of the elastic element and separates from the top surface of the support rib. The limiting contact operation of the support rib can be completed conveniently, which improves the convenience and practicality of the shaping device.

[0012] Preferably, the connecting component includes two pairs of rectangular slots symmetrically opened on the top of the two support bars. The connecting component also includes two L-shaped plates symmetrically fixedly connected to the top of the connecting plate. The bottom of each of the two L-shaped plates can be inserted into and slidably connected in an adjacent rectangular slot. The advantage of this arrangement is that the support bars only need to be sleeved on the top of the side wall of the battery case and the top of the partition wall of the battery case through the clamping slots, and then the two pairs of L-shaped plates on the adjusted support member can be directly inserted into the two rectangular slots to complete the connection operation between the support member and the support bar, which further improves the convenience and practicality of the shaping device.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, the supporting members, supporting ribs and supporting strips can support the left and right side walls and front and rear side walls of the battery shell, and can also support and limit the partition walls of the battery shell. This can effectively prevent the battery shell from denting and deforming due to cooling contraction during the cooling process, ensuring the dimensional accuracy and quality of the battery shell after molding, and effectively improving the quality of the battery shell.

[0015] 2. In this utility model, by setting the transverse spacing adjustment component, the longitudinal spacing adjustment component and the connecting component, the support can adjust the spacing between the two pairs of longitudinal strips and the spacing between the two pairs of transverse strips according to the actual width of the battery case to be shaped and supported and the spacing between the two adjacent battery case partitions inside the battery case. This allows the shaping device to be used to shape and support battery cases of various sizes, improving the applicability and practicality of the shaping device. Attached Figure Description

[0027] Example 2

[0028] According to Example 1, please refer to Figures 2-5The support member 1 includes two pairs of fixed blocks 11 arranged in a rectangle. Two pairs of longitudinal bars 12 are symmetrically fixed to the adjacent sides of the two pairs of fixed blocks 11. Two pairs of transverse bars 13 are symmetrically fixed to the adjacent sides of the two pairs of fixed blocks 11. Two guide rods 14 are symmetrically and movably inserted between the adjacent sides of the two pairs of transverse bars 13 and between the adjacent sides of the two pairs of longitudinal bars 12. The support member 1 also includes two pairs of filler strips 15. Two slots are symmetrically formed on the adjacent sides of each pair of filler strips 15. The two pairs of filler strips 15 are symmetrically engaged with the outer circumference of the two pairs of guide rods 14 through the slots. The two pairs of filler strips 15 are respectively located between the adjacent sides of the two pairs of longitudinal bars 12 and... Between the adjacent sides of the two pairs of horizontal bars 13, the side of the filler strip 15 near the two adjacent fixing blocks 11 is tightly pressed against the side of the adjacent vertical bar 12 or the side of the adjacent horizontal bar 13. Between the two pairs of vertical bars 12, there is a longitudinal spacing adjustment component 5 for adjusting the distance between the two horizontal bars 13 and a transverse spacing adjustment component 6 for adjusting the distance between the two vertical bars 12. The length of the filler strip 15 can be cut according to the distance between the adjacent sides of the two pairs of vertical bars 12 or the distance between the adjacent sides of the two pairs of horizontal bars 13 after adjustment. The distant sides of the two pairs of horizontal bars 13 are slidably connected to the two adjacent support bars 3 through the connecting component 7.

[0029] Specifically, the longitudinal spacing adjustment component 5 and the transverse spacing adjustment component 6 can respectively adjust the spacing between the two pairs of horizontal strips 13 and the two pairs of longitudinal strips 12. In addition, with the two pairs of filler strips 15 cut according to the spacing between the two pairs of longitudinal strips 12 and the two pairs of horizontal strips 13 on the side after adjustment, the support member 1 can adjust the spacing between the two pairs of longitudinal strips 12 and the spacing between the two pairs of horizontal strips 13 according to the actual width of the battery case to be shaped and supported and the spacing between the two adjacent battery case partitions inside the battery case. Thus, the shaping device can be used to shape and support battery cases of various sizes, improving the applicability and practicality of the shaping device.

[0030] refer to Figures 2-4 The longitudinal spacing adjustment component 5 includes two symmetrically distributed connecting plates 51. A bidirectional screw 52 is threaded between the two connecting plates 51. The left and right ends of the bidirectional screw 52 pass through the far sides of the two connecting plates 51 respectively. Two round rods 53 are symmetrically and movably inserted on the near sides of the two connecting plates 51. The left and right ends of the two round rods 53 pass through the far sides of the two connecting plates 51 respectively. A knob is fixedly sleeved at the middle position of the bidirectional screw 52.

[0031] refer to Figures 4-6The lateral spacing adjustment assembly 6 includes two pairs of mounting cavities 61 symmetrically opened on the opposite sides of the two connecting plates 51. The bottom of the two pairs of support ribs 2 is symmetrically rotatably connected to the bottom wall of the mounting cavity 61 by two pairs of first rotating shafts and two pairs of torsion springs. The lateral spacing adjustment assembly 6 also includes two pairs of T-shaped grooves symmetrically opened on the opposite sides of the two pairs of longitudinal bars 12. Two pairs of T-shaped blocks 62 are symmetrically slidably connected in the two pairs of T-shaped grooves. The opposite ends of the two pairs of support ribs 2 are symmetrically hinged to the opposite sides of the two pairs of T-shaped blocks 62. The lateral spacing adjustment assembly 6 also includes two clamping mechanisms 63 symmetrically connected on the two connecting plates 51. The clamping mechanisms 63 are used to clamp the two pairs of support ribs 2.

[0032] refer to Figure 5 and Figure 6 The pressing mechanism 63 includes two rectangular cavities 631 symmetrically opened on the top of the two connecting plates 51. Two pairs of insert rods 632 are symmetrically and movably inserted into the bottom wall of the two rectangular cavities 631. The bottom ends of the two pairs of insert rods 632 pass through the bottom wall of the two rectangular cavities 631 and extend into the two pairs of mounting cavities 61. Two pairs of pressure plates 633 are symmetrically and fixedly connected to the bottom ends of the two pairs of insert rods 632. The two pairs of pressure plates 633 are located directly above the two pairs of support ribs 2 and can press tightly against the top surface of the support ribs 2. Two rectangular plates 634 are symmetrically and fixedly connected between the top ends of the two pairs of insert rods 632. Two pairs of elastic elements 635 are symmetrically and fixedly connected between the bottom of the two rectangular plates 634 and the bottom wall of the two rectangular cavities 631. The pressing mechanism 63 also includes two limiting units 636 symmetrically connected on the two connecting plates 51. The limiting units 636 are used to limit and press the rectangular plates 634 into the two rectangular cavities 631.

[0033] refer to Figure 5 and Figure 6 The limiting unit 636 includes two pairs of limiting blocks 6361 symmetrically fixedly connected to the top of the two connecting plates 51. Two pairs of limiting grooves are symmetrically opened on the side surfaces of the two pairs of limiting blocks 6361 that are far apart. Two limiting plates 6362 are symmetrically slidably connected to the top of the two connecting plates 51. The two limiting plates 6362 can slide towards each other along the length direction of the longitudinal strip 12. The ends of the two limiting plates 6362 that are far apart can be slidably inserted into the two pairs of limiting grooves respectively.

[0034] Specifically, the operator only needs to press down on the two limiting plates 6362 with both thumbs until the two rectangular plates 634 are inserted into the two rectangular cavities 631 respectively. Then, push the two limiting plates 6362 in opposite directions until they move out of the two pairs of limiting grooves. At this point, release the limiting plates 6362, and the pressure plate 633 will move upward under the elastic force of the elastic element 635 and separate from the top surface of the support rib 2. This conveniently completes the limiting release operation of the support rib 2, improving the convenience and practicality of the shaping device.

[0035] refer to Figures 2-4 The connecting component 7 includes two pairs of rectangular slots 71 symmetrically opened on the top of the two support bars 3. The connecting component 7 also includes two L-shaped plates 72 symmetrically fixedly connected to the top of the connecting plate 51. The bottom of each L-shaped plate 72 can be inserted into and slidably connected to an adjacent rectangular slot 71.

[0036] Specifically, the support bar 3 is simply fitted onto the top of the side wall of the battery case and the top of the partition wall of the battery case through the clamping groove 4, and then the two pairs of L-shaped plates 72 on the adjusted support member 1 are directly inserted into the two rectangular grooves 71. This conveniently completes the connection operation between the support member 1 and the support bar 3, further improving the convenience and practicality of the shaping device.

[0037] Working principle: The support strips 3 are cut to the same length according to the width of the battery casing partition. Then, multiple support strips 3 are respectively fitted onto the top of the battery casing side wall and the top of the battery casing partition through the clamping grooves 4.

[0038] Then, based on the width of the inner cavity of the battery casing, determine the number of support members 1 between two adjacent battery casing partitions. Subsequently, determine the width of each support member 1. Next, the worker uses two thumbs to press down on the two limiting plates 6362 until the two rectangular plates 634 are inserted into the two rectangular cavities 631 respectively. Then, push the two limiting plates 6362 in opposite directions until they move out of the two pairs of limiting grooves. At this point, release the limiting plates 6362, allowing the pressure plate 633 to move upward under the elastic force of the elastic member 635 and separate from the top surface of the support rib 2. This conveniently completes the limiting release operation of the support rib 2. Then, push the two pairs of longitudinal bars 12 towards each other until the width of the support member 1 is equal to the required width. Next, press the two rectangular plates 634 back into the two rectangular cavities 631 through the two limiting plates 6362. Then, push the two limiting plates 6362 in opposite directions until they are inserted into the two pairs of limiting grooves. This completes the width adjustment of the support member 1.

[0039] Next, based on the distance between the two support bars 3 at the top of the adjacent battery casing partition, turn the knob to drive the bidirectional screw 52 to rotate. The bidirectional screw 52, ​​together with the round rod 53, drives the two connecting plates 51 to move towards each other so that the distance between the two pairs of horizontal bars 13 on opposite sides is equal to the distance between the two adjacent support bars 3. In this way, the length of the support 1 can be adjusted.

[0040] Subsequently, by fitting the support bar 3 onto the top of the side wall and the top of the partition wall of the battery case through the clamping groove 4, and then directly inserting the two pairs of L-shaped plates 72 on the adjusted support member 1 into the two rectangular grooves 71, the connection between the support member 1 and the support bar 3 can be easily completed. This allows the entire shaping device to be assembled and installed inside the battery case, so that the shaping device can play a supporting role during the cooling process of the battery case and prevent the battery case from denting and deforming due to cooling and shrinkage.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
