[0029] Schematic die positioning mechanism for sealing the terminal module of a resin product
[0030] Reference Figures 1 to 6 , according to a preferred embodiment of the present invention, a die positioning mechanism for sealing the terminal module of a resin product, wherein it should be noted that the structure of the die positioning mechanism for sealing the terminal module of the resin product is as Figure 1 shown, specifically as Figure 1 and 2 shown in the application scenario of the present invention, which includes a connector molding part 10, a gating system 20, two die cavity terminal positioning pins 30, and two connector terminals 40. Specifically, the above-mentioned connector molding part 10 is molded through the gating system 20. At the same time, the two connector terminals 40 are synchronously placed in the connector molding part 10. Additionally, the two die cavity terminal positioning pins 30 are used to define the front ends and middle sections of the two connector terminals 40. However, it should be noted that since the module docking cavity of the connector molding part 10 at the indicated part A needs to be sealed and a traditional in-cavity terminal positioning pin cannot be used, the connector terminal 40 at this location cannot be effectively fixed, resulting in the connector terminal 40 being subjected to the impact force of the flowing resin, causing the positional accuracy of the connector terminal 40 to be unstable, affecting the production yield of the product, and resulting in unstable manufacturing costs. Therefore, in response to this problem, our company provides a positioning mechanism to solve the above problems. It should be noted that the terminal module is the above two connector terminals.
[0031] Specifically, the die positioning mechanism for sealing the terminal module of the resin product includes a moving component 50, and the moving component 50 is movably disposed above the indicated part A.
[0032] Further, the moving component 50 includes a first connection block 51 and a second connection block 52. The bottom of the first connection block 51 contacts the top of the second connection block 52, and two oppositely arranged mounting grooves 5101 are provided on one side of the first connection block 51 close to the second connection block 52. Additionally, the two mounting grooves 5101 together form an 8 - shaped configuration. Specifically, two oppositely arranged insertion holes 5201 are provided on the top of the second connection block 52. The two insertion holes 5201 penetrate through the second connection block 52 and are spaced apart by a predetermined distance. Among them, the two insertion holes 5201 also correspond to the two mounting grooves 5101 one by one.
[0033] It is worth mentioning that the connection method of the above - mentioned first connection block 51 and second connection block 52 can be implemented as a bolt connection, thereby defining the positions of the first connection block 51 and the second connection block 52.
[0034] Further, the mold positioning mechanism for sealing the resin product terminal module further includes two telescopic components 60. When one ends of the two telescopic components 60 are respectively placed in the two mounting grooves 5101, the other ends respectively pass through the two insertion holes 5201 and respectively abut against the two connector terminals 40 at the indicating part A, thereby defining the positions of the two connector terminals 40 at this place. Specifically, each telescopic component 60 includes an elastic member (not shown in the figure) and a moving rod 61. One end of the elastic member is placed in the mounting groove 5101. At the same time, one end of the moving rod 61 abuts against the elastic member, and the other end passes through the corresponding insertion hole 5201 and contacts one of the connector terminals 40. Additionally, it should be noted that the end of the moving rod 61 cooperating with the elastic member is placed in the mounting groove 5101, and at the same time, the dimension of its cross - section is larger than the dimension of the insertion hole 5201, thereby limiting this end in the mounting groove 5101.
[0035] Further, a rhomboid groove 5102 is also provided on one side of the first connection block 51, and its structure is as Figure 1 shown, and this groove is a through - groove. Additionally, the mold positioning mechanism for sealing the resin product terminal module further includes a pin 70. When the pin 70 is movably arranged in the rhomboid groove 5102, specifically as Figure 5As shown in the cross-sectional view, the end of the pin 70 facing away from the first connecting block 51 also cooperates with the external cylinder, that is, when the pin 70 moves to the left by a predetermined distance, the end of the pin 70 placed in the oblique groove 5102 will be squeezed to form the wall of the oblique groove 5102, so that the above-mentioned first connecting block 51 moves upward by a predetermined distance, thereby ensuring that the above-mentioned moving rod 61 can be withdrawn, conversely, when the pin 70 moves to the right by a predetermined distance, the end of the pin 70 placed in the oblique groove 5102 will be squeezed to form the wall of the oblique groove 5102, so that the above-mentioned first connecting block 51 moves downward by a predetermined distance, so that the ends of the two moving rods 61 will contact the two connector terminals 40.
[0036] It should be noted that the moving rod 61 is referred to as the positioning pin 61 below. Specifically, the elastic member is implemented as a round spring with an elastic force of F0. In addition, the cavity area of the positioning pin 61 is S=S1+S2+S3+S4. Figure 7 As shown, and the injection pressure is P, that is, the injection pressure F of the positioning pin 61 is F=P*S, so we need to ensure that F*85%≥F0. That is, before the injection molding flow resin is filled around the connector terminal 40 at the indicated part A, the connector terminal 40 is fixed by the pressure of the positioning pin 61 to prevent the injection pressure from distorting the connector terminal 40. When the injection molding flow resin is filled to the end face of the positioning pin 61 at the end of the connector terminal 40, the injection pressure acts on the positioning pin 61 and F*85%≥F0, ensuring that the positioning pin 61 exits the cavity. During the pressure holding stage, the molten resin fills the cavity space of the positioning pin to achieve a sealing effect.
[0037] In summary, the mold positioning mechanism for sealing the terminal module of the resin product based on the embodiment of the present application is explained, which provides the advantages of convenient limiting, effective avoidance of connector terminal displacement, simple structure, and high practicality for the mold positioning mechanism for sealing the terminal module of the resin product.
[0038] It is worth mentioning that in the embodiment of the present application, the mold positioning mechanism of the resin product terminal module seal is simple in structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the mold positioning mechanism of the resin product terminal module seal provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
