[0062] The square package type terminal includes an enclosed square cavity. Before forming, the square package type terminal is a whole sheet of material, and the sheet of material can be divided into a bottom plate, a first side plate and a second side plate connected to opposite sides of the bottom plate, a first top plate connected to one side of the first side plate away from the second side plate, and a second top plate connected to one side of the second side plate away from the first side plate according to the shape after forming. The forming steps of forming the square package type terminal from the sheet of material include:

[0063] The first step: the first side plate together with the first top plate and the second side plate together with the second top plate are bent relative to the bottom plate, and the bending angle can be adjusted according to actual needs;

[0064] The second step: the forming punch sizes the bent square package type terminal, that is, the forming punch forms a forming cavity of a rectangular cavity, and makes the square package type terminal form within the forming cavity. Each plate of the square package type terminal corresponds to the peripheral wall forming the rectangular cavity. Specifically, the first top plate and the second top plate together form a top plate, which can be opposite and spaced apart, or partially overlapped. The bottom plate, the first side plate, the second side plate and the top plate respectively correspond to the peripheral wall of the rectangular cavity.

[0065] Among them, there are different models of the square package type terminal. Among them, there are square package type terminals with the same width but different heights. When manufacturing such square package type terminals, different molds need to be replaced, which is inconvenient to use; moreover, the size of the finally formed square cavity of the square package type terminal is related to the size of the sheet of material. When the sheet of material is too thick, the size of the square cavity is too small, resulting in inconvenient installation. When the sheet of material is too thin, the size of the square cavity is too large, resulting in the square package type terminal being prone to looseness.

[0066] Refer to Figures 1 to 6As shown in the figure, an embodiment of the first aspect of the present utility model provides a mold assembly, including: a stamping seat 100, a stop member 200, a forming member 300, and an adjusting member 400. The stop member 200 is used to stop a forming punch 500. A forming cavity for forming a square-shaped terminal is formed between the forming punch 500 and the forming member 300. When the position of the stop member 200 along the stamping direction where it stops the forming punch 500 changes, the size of the forming cavity along the stamping direction also changes accordingly. By adjusting the position of the stop member 200 along the stamping direction through the adjusting member 400, the size of the forming cavity along the stamping direction can be adjusted. Only by adjusting the adjusting member 400, square-shaped terminals with the same width but different heights can be manufactured, which is more convenient to use; it can also improve the precision of the square-shaped terminals formed by the sheet metal, thereby improving the product quality.

[0067] Among them, the stamping direction refers to: in a stamping die, the direction in which the mold assembly moves towards the closed die state is the stamping direction. The head of the forming punch 500 has a deep "U" groove with a square-shaped frame opening. The top surface of the forming member 300 is a plane, and the forming member 300 and the head of the forming punch 500 cooperate to form a forming cavity in the shape of a rectangular cavity. The forming member 300 partially extends into the groove of the head of the forming punch 500 and forms a forming cavity in the groove. There is no abutting relationship between the forming punch 500 and the forming member 300. The forming punch 500 controls the relative position between the forming punch 500 and the forming member 300 through the stop member 200.

[0068] Specifically, the stamping seat 100 includes a plurality of templates stacked along the stamping direction. Other components are installed through the templates. For example, two adjacent templates are clamped and fixed, or are fixedly locked to the templates by bolts; among them, the stamping seat 100 includes a bottom template 110 and a stamping body 120. The bottom template 110 has a first end surface 111 along the stamping direction. The stamping body 120 is connected to the first end surface 111. The stamping body 120 includes a plurality of templates stacked along the stamping direction. Through holes are provided at the same position of all the templates in the stamping body 120. All the through holes form an installation hole. One end of the installation hole is blocked by the bottom template 110 to form an installation groove. The stop member 200 and the forming member 300 are passed through the installation groove. One end of the stop member 200 located at the notch of the installation groove is the first end 210, and one end of it located at the bottom of the installation groove is the second end 220. One end of the forming member 300 located at the notch of the installation groove is the third end 310, and one end of it located at the bottom of the installation groove is the fourth end 320.

[0069] The stopper 200 is inserted through the stamping base 100 along the stamping direction, and the first end 210 of the stopper 200 is used to abut against the forming punch 500; the forming member 300 is arranged along the stamping direction and connected to the stamping base 100, and the third end 310 of the forming member 300 is used to cooperate with the forming punch 500 to form a forming cavity; wherein, when the whole stamping die is in the closed die state, the forming punch 500 abuts against the stopper 200, and the forming punch 500 cooperates with the forming member 300 to form a forming cavity, and the forming cavity forms a square-shaped terminal.

[0070] The adjusting member 400 is inserted through the stamping base 100 along the adjusting direction, the adjusting direction is perpendicular to the stamping direction, the adjusting member 400 includes at least a first adjusting portion 410 and a second adjusting portion 420 along the adjusting direction, the first adjusting portion 410 is higher than the second adjusting portion 420 along the stamping direction, and the first adjusting portion 410 abuts against the second end 220 opposite to the first end 210. In this embodiment, an adjusting groove 112 is defined on the surface 111 of the first end 210 of the bottom template 110, the adjusting member 400 is inserted through the adjusting groove 112, the adjusting member 400 is integrally in the shape of a square rod, the adjusting member 400 further includes a main rod portion, the main rod portion is inserted through the adjusting groove 112, and both the first adjusting portion 410 and the second adjusting portion 420 are connected to one surface of the main rod portion away from the bottom of the adjusting groove 112. The fact that the first adjusting portion 410 is higher than the second adjusting portion 420 along the stamping direction means that: the surface of the first adjusting portion 410 away from the bottom of the adjusting groove 112 is higher than the surface of the second adjusting portion 420 away from the bottom of the adjusting groove 112.

[0071] It should be noted that the adjusting member 400 including the first adjusting portion 410 and the second adjusting portion 420 means that: the adjusting member 400 includes at least two adjusting portions, and the heights of the two adjusting portions are different. The adjusting member 400 may further include three or more adjusting portions, which are sequentially named as the first adjusting portion 410, the second adjusting portion 420... the Nth adjusting portion along the adjusting direction, where N≥3 and is a positive integer. Among them, along the increasing direction of N, the height of the adjusting portion increases, or decreases, or is randomly set with different heights and there is no obvious difference relationship. In this embodiment, N = 7, and the heights of the first adjusting portion 410, the second adjusting portion 420... the Nth adjusting portion decrease sequentially along the adjusting direction.

[0072] Among them, the adjusting member 400 is configured to adjust the second adjusting portion 420 to abut against the second end 220 along the adjusting direction, so as to relatively reduce the height of the first end 210 of the forming member 300 along the stamping direction and reduce the height of the forming cavity along the stamping direction. The height of the first adjusting portion 410 along the stamping direction is higher than that of the second adjusting portion 420. When the stopper 200 abuts against the first adjusting portion 410 and switches to abut against the second adjusting portion 420, the height of the stopper 200 itself remains unchanged, and the height of the stopper 200 in the mold assembly is reduced under the influence of the second adjusting portion 420, so that the height of the forming punch 500 is reduced, while the height of the forming member 300 in the mold assembly remains unchanged. The reduction of the height of the forming punch 500 reduces the size of the forming cavity in the height direction.

[0073] It should be understood that by adjusting the first adjusting portion 410 or the second adjusting portion 420 of the adjusting member 400 to abut against the second end 220 of the stopper 200, the height of the first end 210 of the stopper 200 is adjusted, the abutting position of the forming punch 500 and the stopper 200 is changed, and at the same time the height of the forming cavity along the stamping direction is changed, so as to realize the adjustment of the size of the forming cavity along the stamping direction. There is no need to replace the mold, which is more convenient to use, and the size of the forming cavity can be adjusted accordingly according to the size of the sheet material, improving the accuracy of the product and the quality of the product is higher.

[0075] It should be understood that the limiting member 600 is in limiting cooperation with the adjusting member 400 to limit the movement of the adjusting member 400 along the adjusting direction. So that the adjusting member 400 cannot move along the adjusting direction during stamping, and the mold assembly is more stable during stamping. When the limiting member 600 is subjected to an external force, the limiting member 600 moves relative to the stamping seat 100 and separates from the adjusting member 400, so that the adjusting member 400 can move along the adjusting direction to switch the first adjusting portion 410 or the second adjusting portion 420 or other adjusting portions to abut against the second end 220 of the stopper 200.

[0089] It should be understood that when the limiting member 600 is separated from the adjusting member 400 under the action of an external force, the limiting elastic member 140 has a greater second elastic potential energy. When the external force is removed, the limiting elastic member 140 drives the limiting member 600 to move along the direction away from the bottom of the limiting groove 131 until the end of the limiting member 600 away from the bottom of the limiting groove 131 abuts against the notch position of the limiting groove 131, that is, the limiting member 600 is reset to the first position.

[0090] In this embodiment, the limiting groove 131 can be integrally formed on the bottom template 110, or the bottom template 110 is provided with a limiting through hole, and a bolt or a pin is disposed on one side of the bottom template 110 opposite to the surface 111 of the first end 210 to block one end of the limiting through hole to form the limiting groove 131. Wherein, the stamping seat 100 further includes a limiting abutting member 150 connected to the bottom template 110, the limiting abutting member 150 is disposed at the notch position of the limiting groove 131, and the limiting abutting member 150 has a pressing opening, the diameter of the pressing opening is smaller than the diameter of the notch, the limiting member 600 includes a first stepped shaft 610, a second stepped shaft 620 and a third stepped shaft, the first stepped shaft 610 extends out from the pressing opening, the second stepped shaft 620 is disposed through the pressing opening and is in limit cooperation with the through groove of the adjusting member 400 through the missing section of the limiting groove 131, and the third stepped shaft is located within the limiting groove 131 and abuts against the limiting abutting member 150. In use, the user can press the extending end of the first stepped shaft 610 to drive the second stepped shaft 620 to move towards the bottom of the limiting groove 131, the second stepped shaft 620 is separated from the through groove, the diameter of the first stepped shaft 610 is smaller than that of the second stepped shaft 620 and does not interfere with the through groove, the limiting member 600 is completely separated from the adjusting member 400, and the adjusting member 400 can move along the adjusting direction. Wherein, the limiting abutting member 150 is connected to the die base 114 in the bottom template 110.

[0091] Refer to Figure 1 、 Figure 3 And Figure 6As shown, in some embodiments of the present utility model, the stopper 200 includes a first main body portion, a stopper portion and an abutting adjustment portion both connected to the first main body portion. The stopper portion is located at the first end 210 and is used to stop the forming punch 500. The abutting adjustment portion is located at the second end 220 and abuts against the first adjustment portion 410 in the adjustment groove 112.

[0092] In this embodiment, the adjusting member 400 is completely located within the adjusting groove 112. The abutting adjustment portion extends into the adjusting groove 112 and abuts against the adjustment portion. The first main body portion is spaced apart from the first end surface 111 of the bottom template 110, and the forming member 300 directly abuts against the first end surface 111 of the bottom template 110. Thus, the size of the stopper 200 in the stamping direction can be adjusted through the adjustment portion of the adjusting member 400, improving the convenience of use.

[0093] In addition, as shown in Figure 6 the mold assembly includes a fixing member 700 connected to the stamping seat 100 and a balancing elastic member 800. The fixing member 700 is opposite and spaced apart from the first end 210 of the stopper 200 in the stamping direction. The balancing elastic member 800 is disposed between the fixing member 700 and the stopper 200. It should be noted that when the stopper 200 moves in the stamping direction, a moving space is required. The moving space is formed by the interval between the fixing member 700 and the first end 210 of the stopper 200. When there is only the moving space, only the second end 220 of the stopper 200 abuts against the adjustment portion, and the first end 210 of the stopper 200 is in a relaxed state. The stopper 200 is prone to looseness and collision wear during the stamping process, resulting in a reduced service life. A balancing elastic member 800 in the stamping direction is disposed in the moving space to apply an external force to the first end 210 of the stopper 200, so that the stopper 200 is in a static equilibrium state of clamping force in the stamping direction. The vibration force received by the stopper 200 needs to break the static equilibrium to make the stopper 200 vibrate. The stopper 200 is less likely to vibrate, effectively increasing the service life. Among them, an avoidance hole is provided on the end surface of the first end 210 of the stopper 200, and a part of the balancing elastic member 800 is accommodated in the avoidance hole, so that the balancing elastic member 800 has a longer deformation stroke and the control of the elastic force of the balancing elastic member 800 is more convenient.

The first mold assembly is the mold assembly of the first aspect embodiment; the second mold assembly is closed to the first mold assembly in the stamping direction. The second mold assembly includes a forming punch 500. The forming punch 500 abuts against the stopper 200 and cooperates with the forming member 300 to form a forming cavity.

[0095] It should be understood that the stamping die directly adjusts the size of the forming cavity through the first die assembly in the first aspect embodiment, which is convenient for adapting to square package terminals with different heights but the same width, is more convenient to use, and can improve the dimensional accuracy of the square cavity formed by the square package terminals, thereby improving the product quality.

[0096] Referring to Figure 1 As shown, in some embodiments of the present invention, the first die assembly includes a first adjusting member and a second adjusting member both arranged along the adjusting direction, and a first stopping member and a second stopping member both arranged along the stamping direction;

[0097] The forming punch 500 includes a first stamping sub-member 510 and a second stamping sub-member 520 both arranged along the stamping direction. The first stamping sub-member 510 includes a first forming surface for forming the first top plate, and the second stamping sub-member 520 includes a second forming surface for forming the second top plate; wherein, the first adjusting member, the first stopping member and the first stamping sub-member 510 are sequentially abutted along the stamping direction, and the first adjusting member can adjust the forming position of the first forming surface along the stamping direction; the second adjusting member, the second stopping member and the second stamping sub-member 520 are sequentially abutted along the stamping direction, and the second adjusting member can adjust the forming position of the second forming surface along the stamping direction. Moreover, the first adjusting member is fitted with a first limiting member capable of limiting cooperation and separation, and the second adjusting member is fitted with a second limiting member capable of limiting cooperation and separation.

[0098] It should be understood that the square package terminal has a first top plate and a second top plate. By respectively controlling the forming of the first top plate and the second top plate through the first stamping sub-member 510 and the second stamping sub-member 520, the forming of the first top plate and the second top plate is more controllable and the forming accuracy is higher. And the first top plate and the second top plate can be arranged flush or staggered along the stamping direction. For example, when there is partial overlap after the first top plate and the second top plate form the square package terminal, the first top plate needs to be staggered, and when there is no overlap between the first top plate and the second top plate, the first top plate and the second top plate can be arranged flush.
