Description

Technical Field

[0001] The utility model belongs to the technical field of manual molds, and particularly relates to a mold with a controllable mold opening sequence. Background Art

[0002] Lead parts are important components of lead-acid batteries. Since the lead parts have a simple structure and most of their production processes are manual, most of the lead part molds are manual casting molds without the assistance of mechanical equipment. Just because it is a manual casting mold, for some slightly complex lead parts, there are requirements for the sequence of mold opening actions to ensure the quality of the products.

[0003] The mold insert can adjust the size or shape of the mold to meet different production requirements. However, when the driving rod insert disengages from the product, the insert will move with the driving rod and rub against the surface of the lead part, damaging it and affecting the product quality. Summary of the Utility Model

[0004] In view of the problem that in the prior art, the insert moves with the driving rod and rubs against the surface of the lead part, damaging it, the utility model proposes the following technical solutions:

[0005] A mold with a controllable mold opening sequence, comprising: a first moving plate, a third fixed plate, and a third moving plate. A first insert is movably inserted into the third fixed plate, and a second insert is fixedly arranged inside the third moving plate. Multiple molding cavities for product molding are formed among the first insert, the second insert, the first moving plate, the third fixed plate, and the third moving plate. A limiting mechanism is movably inserted into the third fixed plate, one end of the limiting mechanism is movably inserted into the first moving plate, and the end of the limiting mechanism is fixedly connected to the first moving plate.

[0006] Preferably, the limiting mechanism is L-shaped, and one side of the limiting mechanism is attached to one side edge of the insert.

[0007] Preferably, the bottom of the third moving plate is fixedly connected to a second moving plate through a fixing screw, and the second moving plate is connected to the first moving plate through a limiting screw.

[0008] Preferably, the bottom of the third fixed plate is fixedly connected to a second fixed plate through a fixing screw, and the second fixed plate is connected to the first moving plate through a limiting screw.

[0009] Preferably, it further includes a first fixed plate. A driving rod inclinedly arranged is fixedly connected to the middle of the first fixed plate. One end of the driving rod penetrates through the middle of the second fixed plate, one side of the third fixed plate, and extends into the first moving plate, and a section in the middle of the driving rod is movably inserted into the limiting mechanism and the first insert.

[0010] The beneficial effects of the utility model are as follows:

[0011] When the driving rod drives the insert 1 to disengage from the lead part, the limiting mechanism is fixed on the movable plate 1 and presses against the insert 1 at the same time, forcing the insert 1 to move upward. The left component force will not drive the fixed plate 2 and the movable plate 1 to open until the insert 1 is separated from the lead part and the limiting mechanism upward. Only then can the fixed plate 2 and the movable plate 1 be opened, avoiding sliding friction between the product surface and the insert 1 and damaging each other, thereby controlling the product quality and making the product size more precise.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.

[0018] Example

[0019] Figures 1-4 In the present invention, a mold with controllable mold opening sequence comprises: a movable plate 10, a fixed plate 21 and a movable plate 31, wherein an insert 41 is movably inserted inside the fixed plate 31, and an insert 2 42 is fixedly arranged inside the movable plate 31, and a plurality of molding cavities for molding products 70 are formed between the insert 1 41, the insert 2 42, the movable plate 10, the fixed plate 3 21 and the movable plate 3 31, and a limiting mechanism 50 is movably inserted inside the fixed plate 3 21, and one end of the limiting mechanism 50 is movably inserted in the movable plate 10, and the end of the limiting mechanism 50 is fixedly connected to the movable plate 10.

[0020] The limiting mechanism 50 is L-shaped, one side of the limiting mechanism 50 is in contact with the side of the insert 41 , the middle of the limiting mechanism 50 is groove-shaped, and the driving rod 62 is movably inserted in the middle groove of the limiting mechanism 50 .

[0021] Figures 3-4 In it, a second moving plate 32 is fixedly connected to the bottom of the third moving plate 31 through a fixing screw, and the second moving plate 32 is connected to the first moving plate 10 through a limit screw.

[0022] A second fixed plate 22 is fixedly connected to the bottom of the third fixed plate 21 through a fixing screw, and the second fixed plate 22 is connected to the first moving plate 10 through a limit screw.

[0023] Figures 3-4 In it, a first fixed plate 61 is further included. A driving rod 62 which is obliquely arranged is fixedly connected to the middle of the first fixed plate 61. One end of the driving rod 62 penetrates through the middle of the second fixed plate 22, one side of the third fixed plate 21 and extends into the first moving plate 10, and a section in the middle of the driving rod 62 is movably inserted into the limiting mechanism 50 and the first insert 41.

[0024] Working principle: First, an external power drives the first fixed plate 61 and the driving rod 62 to move in the A direction. A distance L1 for opening is formed between the second fixed plate 22 and the third fixed plate 21 and the first moving plate 10, which is convenient for taking out the first insert 41 from the lead part. Then, it continues to move to drive the second fixed plate 22 and the third fixed plate 21 to move away from the first moving plate 10 by a distance L2. Since the limiting mechanism 50 is fixed on the first moving plate 10 and one side of the limiting mechanism 50 abuts against the first insert 41, while the driving rod 62 drives the first insert 41 to take out the product 70, it forces the first insert 41 to move only upward, and the component force acting on it to the left will not drive the second fixed plate 22 and the first moving plate 10 to open by L2 until the first insert 41 is separated from the lead part and the limiting mechanism 50 upward, then the second fixed plate 22 and the first moving plate 10 can be opened. At this time, the movement of the first half of the mechanism is completed. When it continues to move to pull the first moving plate 10 and the second moving plate 32 to open by a distance L3, there is no obstruction in the demolding direction of the product 70 at this time, and the demolding can be completed by using the ejecting device. Thus, the mold opening is completed. Due to the change of force, there may be a situation where the distance L3 between the first moving plate 10 and the second moving plate 32 opens first, but this will not affect the quality of the product 70. (Among them, the first fixed plate 61 and the second fixed plate 22 are connected through a limit screw, the second fixed plate 22 and the third fixed plate 21 are fixed through a screw, the second moving plate 32 and the third moving plate 31 are also fixed through a screw, the first moving plate 10 and the second fixed plate 22 and the second moving plate 32 are connected through a limit screw, the second insert 42 is fixed on the third moving plate 31, and the components fixed through screws can be regarded as a whole during the movement process).

[0025] While the driving rod 62 drives the insert 41 to disengage from the lead part, since the limiting mechanism 50 is fixed on the movable plate 10 and at the same time presses against the insert 41, the insert 41 is forced to move upward only. The left component force will not drive the fixed plate 22 and the movable plate 10 to open until the insert 41 is separated from the lead part and the limiting mechanism 50 upward. Only then can the fixed plate 22 and the movable plate 10 be opened, avoiding sliding friction between the surface of the product 70 and the insert 41 and damaging each other, thereby controlling the quality of the product 70 and making the product 70 more precise and of higher quality.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
