[0003] The above-mentioned and existing technologies have the following defects: when using plastic molds to manufacture products, misalignment occurs when workers align the upper and lower modules, resulting in errors in the precision of the plastic mold.

[0004] Therefore, a precision plastic mold for optical fiber cable plastic boxes is proposed. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision plastic mold for an optical fiber cable plastic box, comprising a shell and a lower module, an upper module mounted on the surface of the shell, a connecting tube mounted on the surface of the lower module, a positioning device provided on the surface of the shell, the positioning device comprising four fixing plates, all of which are fixedly connected to the shell, a lead screw threadedly connected to the surface of the fixing plate, a positioning rod threadedly connected to the arc surface of the lead screw, four connecting plates fixedly connected to the surface of the lower module, a snap-fit ​​frame fixedly connected to the surface of each of the four connecting plates, a damping rod fixedly connected inside the snap-fit ​​frame, a protective block fixedly connected to one end of the damping rod, a spring sleeved on the arc surface of the damping rod, and both ends of the spring fixedly connected to the snap-fit ​​frame and the protective block respectively.

[0007] The effects achieved by the above components are as follows: By setting up a positioning device, and utilizing the cooperation between the fixed plate, lead screw, positioning rod, connecting plate, snap-fit ​​frame, damping rod, protective block, and spring, the position between the upper and lower modules can be positioned. This avoids misalignment when workers align the upper and lower modules during actual plastic mold manufacturing, which could lead to errors in the precision of the plastic mold.

[0008] Preferably, an auxiliary frame is fixedly connected to the surface of the snap-fit ​​frame, and the vertical cross-section of the auxiliary frame is trapezoidal.

[0009] The effect achieved by the above components is that the positioning rod will pass through the auxiliary frame on the snap-fit ​​frame and enter the snap-fit ​​frame. At this time, the auxiliary frame can increase the opening at the snap-fit ​​frame to facilitate the entry of the positioning rod.

[0010] Preferably, one end of the positioning rod is fixedly connected to a pointed cone, which is a stainless steel cone.

[0011] The effect achieved by the above components is that the positioning rod will drive the pointed cone to move, at which time the pointed cone can easily enter the positioning rod into the snap-fit ​​frame.

[0017] The effect achieved by the above components is that the lead screw will drive the anti-slip pad to move. At this time, the anti-slip pad can increase the friction between the lead screw and the contact surface of the fixed plate, and prevent the lead screw from slipping.

[0018] Preferably, one end of the lead screw is fixedly connected to an elastic rope, and the other end of the elastic rope is fixedly connected to a fixed plate.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1.

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figures 1-6 As shown, this utility model provides a precision plastic mold for optical fiber cable plastic boxes, including a housing 1 and a lower module 3. An upper module 2 is installed on the surface of the housing 1, a connecting tube 4 is installed on the surface of the lower module 3, and a positioning device 5 is provided on the surface of the housing 1.

[0032] The specific setup and function of its positioning device 5 will be explained in detail below.

[0033] like Figures 2-6As shown, the positioning device 5 includes four fixing plates 501, all of which are fixedly connected to the housing 1. A lead screw 502 is threaded onto the surface of each fixing plate 501, and a positioning rod 503 is threaded onto the arc surface of the lead screw 502. Four connecting plates 504 are fixedly connected to the surface of the lower module 3, and a snap-fit ​​frame 505 is fixedly connected to the surface of each of the four connecting plates 504. A damping rod 506 is fixedly connected inside the snap-fit ​​frame 505, and a protective block 507 is fixedly connected to one end of the damping rod 506. A spring 508 is fitted onto the arc surface of the damping rod 506, and both ends of the spring 508 are respectively connected to the snap-fit ​​frame 506. The retaining frame 505 and the protective block 507 are fixedly connected. An auxiliary frame 509 is fixedly connected to the surface of the retaining frame 505. The vertical cross-section of the auxiliary frame 509 is trapezoidal. The positioning rod 503 passes through the auxiliary frame 509 on the retaining frame 505 to enter the interior of the retaining frame 505. At this time, the auxiliary frame 509 can increase the opening at the retaining frame 505 to facilitate the entry of the positioning rod 503. One end of the positioning rod 503 is fixedly connected to a pointed cone 510, which is a stainless steel cone. The positioning rod 503 will drive the pointed cone 510 to move. At this time, the pointed cone 510 can facilitate the entry of the positioning rod 503 into the retaining frame 505. Inside the 5th section, a plurality of ball bearings 511 are rotatably connected to the surface of the positioning rod 503. These ball bearings 511 are slidably connected to the inner wall of the locking frame 505. The positioning rod 503 drives the ball bearings 511 to slide along the inner wall of the locking frame 505. At this time, the ball bearings 511 reduce the friction between the positioning rod 503 and the locking frame 505. A protective pad 512 is fixedly connected to the surface of the protective block 507. The protective pad 512 is a rubber pad. When the pointed cone 510 abuts against the protective pad 512, the rubber protective pad 512 protects the protective block 507. The lead screw 50... An anti-slip pad 513 is fixedly connected to the arc surface of plate 2. The anti-slip pad 513 is slidably connected to the fixing plate 501. The lead screw 502 will drive the anti-slip pad 513 to move. At this time, the anti-slip pad 513 can increase the friction between the contact surface of the lead screw 502 and the fixing plate 501, preventing the lead screw 502 from slipping. One end of the lead screw 502 is fixedly connected to an elastic rope 514. The other end of the elastic rope 514 is fixedly connected to the fixing plate 501. The lead screw 502 will drive one end of the elastic rope 514 to move. At this time, the elastic rope 514 can prevent the lead screw 502 from being lost when it is separated from the fixing plate 501.

[0034] The overall working principle is as follows: When the upper module 2 needs to be docked with the lower module 3, the outer shell is first moved closer to the lower module 3. Then, the outer shell will drive the upper module 2 to move, and at the same time, the outer shell will drive the fixing plate 501 to move in the same direction. Next, the fixing plate 501 will drive the positioning rod 503 to move closer to the snap-fit ​​frame 505 at the connecting plate 504 on the lower module 3. Then, the positioning rod 503 will drive the cone 510 to move. At this time, the cone 510 can facilitate the positioning rod 503 to enter the snap-fit ​​frame 505. At the same time, the positioning rod 503 will pass through the auxiliary frame 509 on the snap-fit ​​frame 505 to enter the snap-fit ​​frame 505. At this time, the auxiliary frame 509 can increase the size of the snap-fit ​​frame 505. The opening facilitates the entry of the positioning rod 503. The positioning rod 503 then drives the ball bearing 511 to slide along the inner wall of the locking frame 505. At this time, the ball bearing 511 reduces the friction between the positioning rod 503 and the locking frame 505. Then, when the cone 510 abuts against the protective pad 512, the rubber protective pad 512 protects the protective block 507. Simultaneously, the protective pad 512 transfers the compressive force of the cone 510 to the protective block 507. The protective block 507 then compresses the spring 508, and simultaneously, the protective block 507 causes the damping rod 506 to retract. At this time, the damping rod 506 prevents the spring 508 from repeatedly bouncing. Finally, the protective block 507, the spring 508, and the damping rod... Rod 506 can buffer the positioning rod 503. When the positioning rod 503 needs to be disassembled, the lead screw 502 can be rotated. The lead screw 502 will then disengage from the fixing plate 501 and the positioning rod 503 through its own threads. At the same time, the lead screw 502 will drive one end of the elastic rope 514 to move. The elastic rope 514 can prevent the lead screw 502 from being lost when it is disengaged from the fixing plate 501. When the positioning rod 503 needs to be installed, the lead screw 502 is rotated in the opposite direction. The lead screw 502 will then fix the fixing plate 501 and the positioning rod 503 through its own threads. At the same time, the lead screw 502 will drive the anti-slip pad 513 to move. The anti-slip pad 513 can increase the slip resistance of the lead screw 503. The friction between the contact surface of the 02 and the fixed plate 501 prevents the lead screw 502 from slipping. By setting up the positioning device 5, the position between the upper module 2 and the lower module 3 can be positioned by the cooperation between the fixed plate 501, the lead screw 502, the positioning rod 503, the connecting plate 504, the snap-fit ​​frame 505, the damping rod 506, the protective block 507 and the spring 508. This avoids misalignment when the workers align the upper module 2 and the lower module 3 during the actual use of plastic mold manufacturing, which would cause errors in the precision of the plastic mold. This reduces various product defects caused by mold misalignment, improves the precision between the upper module 2 and the lower module 3, and further improves the quality of the product.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
