Description

Technical Field

[0001] The utility model belongs to the technical field of plug injection molding, and in particular relates to a multi-station plug injection molding tool. Background Art

[0002] The plug injection molding tool is an indispensable tool for producing plugs. It is mainly composed of a movable mold, a fixed mold, and a device that drives the movable mold and the fixed mold to precisely match. Injection molding technology is particularly suitable for manufacturing parts with complex shapes and high precision requirements. During the manufacturing process, the plastic raw material is heated to a molten state and then injected into the cavity formed by the movable mold and the fixed mold under high pressure. After cooling and solidification, the finished plug can be obtained.

[0003] However, there are still some links in the current plug injection molding production process that need to be improved. For example, the placement of electronic components usually relies on manual operation, which not only increases the complexity of the operation, but also easily causes excessive colloid to adhere to the surface of the pins of the electronic components, causing inconvenience for subsequent processing. More importantly, after the plug is formed, it needs to be manually removed from the mold, which not only increases the labor intensity, but also may lead to a decrease in production efficiency.

[0004] Therefore, it is very necessary to invent a multi-station plug injection molding tool. Utility Model Content

[0006] The plug-in pop-up mechanism includes a pop-up plate, a socket, a limit pin, a pop-up spring, a plug-in plate, a slot, a return spring and a pull rod. The pop-up plate is provided with the socket corresponding to the lower injection mold, the limit pin is fixedly installed below the pop-up plate, and the pop-up plate is elastically installed in the installation slot by sliding through the pop-up spring; the plug-in plate is elastically installed in the lower part of the installation slot by sliding through the return spring, the slot is opened on the plug-in plate, and the pull rod fixedly installed on the plug-in plate slides out of the injection molding base to the outside.

[0007] Preferably, the pop-up plate is a rectangular structure, the socket provided on the pop-up plate matches the pin of the plug, and the pop-up plate is located above the plug board.

[0008] Preferably, the limit pin fixedly installed on the pop-up plate is an "L"-shaped structure, and the limit pin is located above the card slot set on the plug-in board. The card slot is an "L"-shaped slot with a beveled edge, and the card slot allows the limit pin to be limited and fixed.

[0009] Preferably, the pull rod is located outside the return spring, the pull rod is a "U"-shaped structure, and a slot hole allowing the pull rod to pass through is provided on the injection molding base.

[0010] Preferably, the pop-up plate is located on one side of the lower injection mold, and the lower injection mold, the upper injection mold and the pop-up plate form a complete plug injection cavity.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model abandons the operation mode in the traditional technology. By introducing a unique plug-in ejection mechanism, the function of automatically ejecting the formed plug without manual operation is realized, which greatly improves the convenience of operation, significantly reduces the labor intensity of the staff, and significantly shortens the operation time.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a multi-station plug injection molding tool, which includes an injection molding base 1, a plug-in pop-up mechanism 2, a mounting groove 3, a lower injection mold 4 and a positioning hole 5. The plug-in pop-up mechanism 2 is installed in the mounting groove 3 opened on the injection molding base 1, and a plurality of the lower injection molds 4 are fixedly installed on the injection molding base 1, and the positioning holes 5 are opened at the four corners of the injection molding base 1.

[0022] The plug-in pop-up mechanism 2 includes a pop-up plate 21, a socket 22, a limit pin 23, a pop-up spring 24, a plug-in plate 25, a slot 26, a reset spring 27 and a pull rod 28. The pop-up plate 21 is provided with the socket 22 corresponding to the lower injection mold 4, the limit pin 23 is fixedly installed below the pop-up plate 21, and the pop-up plate 21 is elastically installed in the installation slot 3 by sliding through the pop-up spring 24; the plug-in plate 25 is elastically installed in the lower part of the installation slot 3 by sliding through the reset spring 27, the plug-in plate 25 is provided with the slot 26, and the pull rod 28 fixedly installed on the plug-in plate 25 slides out of the injection molding base 1. The plug-in pop-up mechanism 2 not only realizes fast and accurate positioning, avoids the problem of excessive colloid attached to the surface of the pin in the subsequent injection molding process, but also realizes the function of automatically popping out the formed plug without manual operation, which greatly improves the convenience of operation, significantly reduces the labor intensity of the staff, and significantly shortens the operation time.

[0023] Embodiment 1:

[0024] Specifically, the pop-up plate 21 is a rectangular structure, and the socket 22 provided on the pop-up plate 21 perfectly matches the pin of the plug, ensuring that the pin can be accurately and quickly inserted into the socket 22, providing a solid foundation for subsequent operations. At the same time, the pop-up plate 21 is cleverly arranged above the plug board 25. Not only is it conducive to the docking of the pin and the socket, but also after the injection molding of the plug is completed, the pop-up plate 21 can quickly eject the plug without manual operation, greatly improving production efficiency and reducing the labor intensity of the staff.

[0025] Specifically, the limit pin 23 fixedly installed on the pop-up plate 21 is an "L"-shaped structure, which not only ensures the stability and reliability of the limit pin 23, but also enables it to work accurately with the card slot 26 on the plug-in board 25. The limit pin 23 is located above the card slot 26 provided on the plug-in board 25, and the card slot 26 is designed as an "L"-shaped slot with a bevel. This design allows the limit pin 23 to slide smoothly along the bevel of the card slot 26 when the pop-up plate 21 slides downward, and is finally fixed by the bottom of the card slot 26. This limiting and fixing method not only ensures the stability of the pop-up plate 21 during the injection molding process, but also enables the limit pin 23 to slide out of the card slot 26 through operation after the injection molding is completed, thereby driving the pop-up plate 21 to rise and automatically ejecting the plug.

[0026] Specifically, the pull rod 28 is located outside the return spring 27, and the pull rod 28 is a "U"-shaped structure. The injection molding base 1 is provided with a slot hole allowing the pull rod 28 to pass through, ensuring that the pull rod can move smoothly during operation without any obstruction.

[0027] Specifically, the pop-up plate 21 is located on one side of the lower injection mold 4, and the lower injection mold 4, the upper injection mold and the pop-up plate 21 form a complete plug injection cavity. During the injection molding process, the lower injection mold 4 and the upper injection mold are tightly closed to form a closed injection cavity. The plastic raw material is injected into this cavity under high pressure, and a plug is formed after cooling and solidification. When the injection molding is completed, the molded plug can be quickly ejected from the injection molding cavity by operating the pull rod 28, without manual operation, which greatly improves the production efficiency.

[0028] Specifically, the lower injection mold 4 and the upper injection mold are a fixed mold and a movable mold respectively, and the upper injection mold is connected to the driving module.

[0029] Embodiment 2:

[0030] First, insert each pin into the socket 22 of the plug-in pop-up mechanism 2, turn on the drive module to drive the upper injection mold to descend, and during the descent of the upper injection mold, the upper injection mold first presses the pop-up plate 21, and the pop-up plate 21 descends and compresses the pop-up spring 24. During this process, the limit pin 23 slides smoothly along the oblique edge of the slot 26 set in the plug-in board 25, and the plug-in board 25 slides to one side under the pressure of the inclined surface and compresses the reset spring 27. When the limit pin 23 reaches the bottom of the slot 26, the reset spring 27 is reset and finally fixed by the bottom of the slot 26. The plastic raw material is injected into this cavity under high pressure, and a plug is formed after cooling and solidification.

[0031] After the plug is injection molded, the drive module drives the upper injection mold to reset, and the plug-in board 25 is manually pulled to slide by the pull rod 28, and the reset spring 27 is compressed. At this time, the limit pin 23 is disengaged from the card slot 26 with the help of the elastic force of the pop-up spring 24, and the pop-up plate 21 pops up upward, driving the injection molded plug to disengage from the lower injection mold 4, and it is manually pulled out, and the pins of the electronic components of the plug to be injection molded are re-inserted into the plug-in pop-up mechanism 2.

[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
