Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 1 and 7, the machining device for the storage battery tray assembly in the technical scheme of the invention comprises an injection mold for injection molding of a storage battery bottom box, wherein the injection mold comprises a cavity 3 and a core, and the core comprises a uncovered rectangular frame 1 and a frame cover 2. The rectangular frame 1 includes a bottom plate and side plates integrally connected to four sides of the bottom plate, the bottom plate includes a plurality of moving portions 10, and the moving portions 10 are connected to a telescopic mechanism 100. The telescopic mechanism 100 drives the moving part 10 to move towards the inner side of the rectangular frame 1, so that the outer side of the mold core is separated from the inner side of the storage battery bottom box, and demolding is realized. The mold core adopting the technical scheme has a novel demolding mode, and when demolding is carried out, the outer side and the surface of the mold core are separated from the inner side surface of the storage battery bottom box, so that the condition that the mold core collides or scratches and the like are caused to the inner side of the storage battery box when demolding is avoided, and the quality of the storage battery box is ensured.

As shown in fig. 1 and 2, the moving section 10 includes a first moving plate 11 having an inverted trapezoidal shape with a rectangular bottom surface, second moving plates 12 are respectively disposed on the outer sides of the four side surfaces of the first moving plate 11, and a third moving plate 13 is disposed between the first moving plate 11 and the second moving plate 12. The first moving plate 11, the four second moving plates 12 and the four third moving plates 13 form a rectangular bottom plate. The contact surface between two adjacent moving plates 11 has high smoothness, and the requirements of the shape and the smoothness of the inner cavity of the storage battery box after splicing are met. The side of the rectangular frame 1 is integrally and fixedly connected with the bottom plate, and when the four second moving plates 12 and the four third moving plates 13 move, the side moves along with the bottom plate connected with the side.

As shown in fig. 5 to 7, the telescopic mechanism 100 includes a lifting column 111 connected to the first moving plate 11, and the lifting column 111 drives the first moving plate 11, the four second moving plates 12, and the four third moving plates 13 to move toward the inside of the rectangular frame 1 under the action of mold opening of the press.

As shown in fig. 6, the second moving chute 121 and the third moving chute 131 are respectively disposed on the second moving plate 12 and the third moving plate 13 toward the axis of the moving column. The second and third

sliding chutes

121 and 131 are respectively provided therein with a second slider 122 and a third slider 132. The second slider 122 and the third slider 132 are respectively hinged with a second lifting rod 123 and a third lifting rod 133, and the other ends of the second lifting rod 123 and the third lifting rod 133 are hinged with the lifting column 111. The second lifting rod 123 and the third lifting rod 133 drive the four second moving plates 12 and the four third moving plates 13 to move towards the inner side of the rectangular frame 1 along with the movement of the lifting column 111. The third moving chute 131 is longer than the second moving chute 121. The lifting column 111 passes through the frame cover 2, and the fixing plate 112 is sleeved on the part of the lifting column 111, which is positioned at the bottom of the frame cover 2.

As shown in fig. 5 and 7, the steps and the tracks of the telescopic mechanism 100 driving the moving part 10 are as follows:

first, the lifting column 111 drives the first moving plate 11 to move upward, and the first moving plate 11 is drawn out from the bottom plate. During the upward movement of the first moving plate 11 along with the lifting column 111, the second lifting rod 123 and the third lifting rod 133 respectively drive the second slider 122 and the third slider 132 to slide. When the second sliding block 122 and the third sliding block 132 slide to the ends of the second moving chute 121 and the third moving chute 131 close to the lifting column 111, respectively, the lifting column 111 continues to move upwards, and at this time, the sliding blocks cannot move in the moving chutes any more; therefore, the lifting column 111 moves upward with the moving part connected to the lifting rod. Since the length of the third moving chute 131 is greater than that of the second moving chute 121. The second moving plate 12 moves upward earlier than the third moving plate 13.

Since the first moving plate 11 is in the shape of an inverted trapezoid with a rectangular bottom surface, after the first moving plate 11 ascends, and the ascending distance is not more than the thickness of the first moving plate 11, the second moving plate 12 also ascends, the contact surfaces between the second moving plate 12 and the first moving plate 11 and the third moving plate 13 are also inclined surfaces, after the second moving plate 12 and the first moving plate 11 ascend, the third moving plate 13 can move inward for a certain distance, and the moving parts move in sequence without interference. The first moving plate 11 ascends to provide a space for the second moving plate 12 to move inward, and the second moving plate 12 ascends to provide a space for the third moving plate 13 to move inward.

For the convenience of demolding, the second moving plate 12 and the third moving plate 13 do not need to move and displace excessively inwards, and when the moving plates move, contact parts are still arranged between the moving plates, so that the moving plates can move oppositely to the moving plates when the mold is opened and the moving track is fixed when the mold is closed.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art and related arts based on the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
