Description

Technical Field

[0001] This utility model relates to the field of connector manufacturing technology, and in particular to a connector float plate mold. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] The molded product is then ejected through an ejector structure. However, the connectors ejected by the ejector structure vary depending on the usage environment and the manufacturer. For example, connectors used for wire-to-wire connections have multiple equally spaced small openings, which can easily cause damage to the connector due to uneven force when ejecting it using a traditional ejector structure. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a connector float plate mold, which solves the problem that connectors used for wire-to-wire connections have multiple equally spaced small openings, which can easily cause damage to the connector due to uneven force when ejecting the connector using traditional ejection structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a connector float plate mold, comprising an upper mold base and a lower mold base, and a concave mold and a convex mold disposed between the upper mold base and the lower mold base. The inner cavity of the concave mold is provided with a boss, and the upper end of the boss is provided with two adjacent convex strips. The upper ends of the two convex strips are provided with a plurality of equally spaced notches. The upper end of the boss is provided with a first ejector pin located between the two convex strips and a second ejector pin located beside the opposite end walls of the two convex strips.

[0006] Furthermore, there are no fewer than four first pins, which are evenly distributed between the two protruding strips.

[0007] Furthermore, there are no fewer than four second pins, distributed in pairs on the left and right sides of the two protrusions.

[0008] Furthermore, the inner cavity of the die is also provided with four protrusions, and the four protrusions are located next to the four corners of the boss.

[0009] Furthermore, the inner cavity of the die is also equipped with multiple third ejector pins arranged around the boss.

[0010] Furthermore, there are no fewer than six third pins, and the third pins located at the four corners of the boss are located between the protruding column and the boss.

[0011] Furthermore, ejector bars are provided on both sides of the opposite side wall of the die, with the ejector bars located between the two protrusions, and one ejector bar located next to the feed cavity that communicates with the die.

[0012] Furthermore, the lower end face of the punch is provided with a first recess corresponding to the boss, and a second recess is provided inside the first recess to receive the protrusion.

[0013] Furthermore, a protrusion that abuts against the upper end face of the protrusion is provided in the second concave opening.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, when it is necessary to eject the workpiece in the lower mold base, the first ejector pin and the second ejector pin push the workpiece to move in the cavity mold. Since the first ejector pin is located between the two protrusions and the second ejector pin is located on the side of the two protrusions, the uniformity of the separation of the workpiece and the cavity mold is ensured, so as to avoid the workpiece from being damaged when separating from the cavity mold.

[0025] Please refer to Figure 1-4As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a connector float mold, including an upper mold base 10 and a lower mold base 20, and a concave mold 31 and a convex mold 32 disposed between the upper mold base 10 and the lower mold base 20. The inner cavity of the concave mold 31 is provided with a boss 311, and the upper end of the boss 311 is provided with two adjacent convex strips 312. The upper ends of the two convex strips 312 are provided with a plurality of equally spaced notches 313. The upper end of the boss 311 is provided with a first ejector pin 33 located between the two convex strips 312 and a second ejector pin 34 located beside the opposite end walls of the two convex strips 312. When the workpiece 1 needs to be ejected from the lower mold base 20, the first ejector pin 33 and the second ejector pin 34 push the workpiece 1 to move in the cavity mold 31. Since the first ejector pin 33 is located between the two protrusions 312 and the second ejector pin 34 is located on the side of the two protrusions 312, the uniformity of the separation of the workpiece 1 and the cavity mold 31 is ensured, so as to avoid the workpiece 1 from being damaged when separating from the cavity mold 31.

[0026] For example, there are no fewer than four first ejector pins 33, which are evenly distributed between the two protrusions 312. The length of the four first ejector pins 33 arranged together is the same as the length of the two protrusions 312, so as to ensure the uniformity of the movement of the workpiece 1 when the first ejector pins 33 push it.

[0027] For example, there are no fewer than four second ejector pins 34, distributed in pairs on the left and right sides of the two protrusions 312. Two of the four ejector pins 34 are located on the left side of the protrusions 312 and two are located on the right side of the protrusions 312 to further enhance the smoothness of separation between the workpiece 1 and the die 31.

[0028] Specifically, with the cooperation of the first ejector pin 33 and the second ejector pin 34, the stability of the separation of the workpiece 1 and the boss 311 can be guaranteed.

[0029] For example, the inner cavity of the die 31 is also provided with four protrusions 35, and the four protrusions 35 are located next to the four corners of the boss 311. The four protrusions 25 are used to open holes in the workpiece 1 to meet the subsequent application requirements of the workpiece 1.

[0030] For example, the inner cavity of the die 31 is also provided with a plurality of third ejector pins 36 arranged around the boss 311. The third ejector pins 36 are used to push the workpiece 1 and the die 31 apart, specifically located at the connection between the boss 311 and the die 31, so as to enhance the stability of the separation of the workpiece 1 and the die 31.

[0031] Specifically, there are no fewer than six third ejector pins 36, and the third ejector pins 36 located at the four corners of the boss 311 are situated between the protruding post 35 and the boss 311. Figure 2 For example, three of the six third ejector pins 36 are located in the upper part of the inner cavity of the die 31, and three are located in the lower part of the inner cavity of the die 31.

[0032] For example, each of the two opposite side walls of the die 31 is provided with a top strip 37, the top strip 37 is located between the two protrusions 35, and one top strip 37 is located next to the feed cavity 21 communicating with the die 31. Figure 2 As shown, there are at least two ejector bars 37, with one ejector bar 37 located between two protrusions 35 and the other ejector bar 37 located between two other protrusions 35, in order to cooperate with the first ejector pin 33, the second ejector pin 34 and the third ejector pin 36 to enhance the smoothness of separation between the workpiece 1 and the die 31.

[0033] The lower end face of the punch 32 is provided in the first recess 321 of the corresponding boss 311, and the first recess 321 is provided with a second recess 322 for receiving the protrusion 312.

[0034] The second recess 322 is provided with a protrusion 323 that abuts against the upper surface of the protrusion 312.
