Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a positioning structure for quick installation of mother and child molds. Background Technology
[0002] In the field of mold manufacturing and production, the application of mother-and-child molds is extremely widespread. However, the existing methods of installing mother-and-child molds mostly rely on manual operation, requiring workers to manually align various parts of the mold. This is not only cumbersome but also time-consuming. During the installation process, workers have to repeatedly adjust the mold position to ensure accurate positioning. This process is prone to human error, which further prolongs the installation time and reduces production efficiency. In addition, due to the lack of effective guiding and positioning devices, the mold is prone to displacement and shaking during installation, resulting in inaccurate positioning and affecting the molding quality of the mold. Therefore, we have introduced a positioning structure for quick installation of mother-and-child molds. Utility Model Content
[0003] The main purpose of this utility model is to provide a positioning structure for quick installation of mother and child molds, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] The positioning structure for quick installation of mother-daughter molds includes a U-shaped mounting base. A U-shaped mounting plate is fixedly connected to the middle of the right end of the U-shaped mounting base. A control mechanism is fixedly installed on the right inner wall of the U-shaped mounting plate. Two through-hole upper guide grooves are opened on the upper part of the right end of the U-shaped mounting base, and two through-hole lower guide grooves are opened on the lower part of the right end of the U-shaped mounting base. An upper mounting component is threadedly connected to the upper part of the outer surface of the control mechanism, and a lower mounting component is threadedly connected to the lower part of the outer surface of the control mechanism. Fixing blocks are fixedly connected to the lower front end and the lower rear end of the U-shaped mounting base, and fixing holes that pass through the upper end of the two fixing blocks are opened.
[0006] Preferably, the control mechanism includes a servo motor, with a main bevel gear fixedly mounted on the output end of the servo motor. An upper auxiliary bevel gear is meshed with the upper surface of the main bevel gear, and an upper lead screw is fixedly connected to the upper end of the upper auxiliary bevel gear. A lower auxiliary bevel gear is meshed with the lower surface of the main bevel gear, and a lower lead screw is fixedly connected to the lower end of the lower auxiliary bevel gear. The right end of the servo motor is fixedly connected to the right inner wall of the U-shaped mounting plate, and the left end of the servo motor is fixedly connected to the right end of the U-shaped mounting base. The output end of the servo motor passes through the right end of the U-shaped mounting base and extends into the U-shaped mounting base.
[0007] By adopting the above technical solution, the meshing transmission between the main bevel gear and the upper and lower auxiliary bevel gears can simultaneously drive the upper and lower lead screws to rotate, thereby enabling the upper and lower mounting components to move quickly and achieving rapid positioning and installation of the mother mold body and the child mold body.
[0008] Preferably, the upper lead screw and the lower lead screw are arranged in a mirror image, the upper end of the upper lead screw is movably connected to the upper inner wall of the U-shaped mounting base via a rotating shaft, and the lower end of the lower lead screw is movably connected to the lower inner wall of the U-shaped mounting base via a rotating shaft.
[0009] By adopting the above technical solution: the upper lead screw and the lower lead screw are distributed in a mirror image. Under the drive of the control mechanism, the main bevel gear drives the upper and lower auxiliary bevel gears to rotate, thereby making the upper lead screw and the lower lead screw rotate synchronously. This synchronous rotation enables the upper mounting component and the lower mounting component to move towards or away from each other at the same speed, so that the sub-mold body and the mother mold body can be accurately docked.
[0010] Preferably, the upper mounting assembly includes an upper transmission plate, two upper guide plates are fixedly connected to the right end of the upper transmission plate, an upper limit plate is fixedly connected to the right end of each of the two upper guide plates, a sub-mold body is fixedly connected to the left end of the upper transmission plate, a sealing sleeve is fixedly connected to the lower middle part of the sub-mold body, positioning pins are fixedly connected to the four corners of the lower end of the sub-mold body, and the inner wall surface of the upper transmission plate is threadedly connected to the outer surface of the upper lead screw.
[0011] Preferably, the lower mounting assembly includes a lower transmission plate, two lower guide plates are fixedly connected to the right end of the lower transmission plate, and a lower limit plate is fixedly connected to the right end of each of the two lower guide plates. A female mold body is fixedly connected to the left end of the lower transmission plate, and positioning holes are opened at the four corners of the upper end of the female mold body. The inner wall surface of the lower transmission plate is threadedly connected to the outer surface of the lower lead screw.
[0012] Preferably, the two upper guide plates are movably sleeved in the corresponding two upper guide grooves, the sealing sleeve is movably sleeved in the mother mold body, and the four positioning pins are movably sleeved in the corresponding four positioning holes.
[0013] By adopting the above technical solution, four positioning pins are movably connected with the corresponding four positioning holes, forming the core positioning structure for the installation and positioning of the mother mold body and the child mold body. During the process of the positioning pins being inserted into the positioning holes, the two work closely together to simultaneously constrain the relative positions of the child mold body and the mother mold body in both horizontal and vertical directions, thereby realizing the positioning between the mother mold body and the child mold body.
[0014] Preferably, the two lower guide plates are respectively movably sleeved in the corresponding two lower guide grooves.
[0015] By adopting the above technical solution: during the process of the lower lead screw driving the lower transmission plate to move, the lower guide plate slides along the lower guide groove, which strictly limits the movement trajectory of the lower transmission plate, so that it can only move in the preset direction, thus avoiding installation errors caused by offset.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. In this utility model, automated installation is achieved through a control mechanism. After the servo motor is turned on, its output end drives the main bevel gear to rotate. The main bevel gear meshes with the upper and lower auxiliary bevel gears, which respectively drive the upper and lower lead screws to rotate synchronously. The rotation of the upper lead screw causes the upper transmission plate to move downward along the upper lead screw, and the rotation of the lower lead screw causes the lower transmission plate to move upward along the lower lead screw, thereby achieving rapid docking of the mother mold body and the daughter mold body. The entire installation process is highly automated, requiring no repeated manual adjustments, greatly shortening the installation time and improving production efficiency.
[0018] 2. In this utility model, the upper guide plate slides in the corresponding upper guide groove, and the lower guide plate slides in the corresponding lower guide groove, providing precise guidance for the movement of the mother mold body and the child mold body. At the same time, the positioning pin at the lower end of the child mold body is accurately inserted into the positioning hole at the upper end of the mother mold body, and the sealing sleeve is movably fitted into the mother mold body, further ensuring the positioning accuracy of the mother mold body and the child mold body. This precise positioning method can effectively prevent the mold from shifting and shaking during installation, ensure the precise docking of the mother mold body and the child mold body, improve the molding quality of the mold, reduce the defect rate, and provide a strong guarantee for the production of high-precision products.

[0029] In this embodiment, the control mechanism 3 includes a servo motor 31. A main bevel gear 32 is fixedly mounted on the output end of the servo motor 31. An upper auxiliary bevel gear 33 is meshed with the upper part of the outer surface of the main bevel gear 32.

The right end of the servo motor 31 is fixedly connected to the right inner wall of the U-shaped mounting plate 2, and the left end of the servo motor 31 is fixedly connected to the right inner wall of the U-shaped mounting plate 2.

The four corners of the lower end of the sub-mold body 64 are fixedly connected to positioning pins 66. The inner wall of the upper drive plate 61 is threadedly connected to the outer surface of the upper lead screw 35. The lower mounting assembly 7 includes a lower drive plate 71. The right end of the lower drive plate 71 is fixedly connected to two lower guide plates 72. The right end of each of the two lower guide plates 72 is fixedly connected to a lower limit plate 7. 3. The left end of the lower transmission plate 71 is fixedly connected to the female mold body 74. The four corners of the upper end of the female mold body 74 are provided with positioning holes 75.

The lower transmission plate 71 moves upward along the lower lead screw 36, and the two lower guide plates 72 slide and guide within the corresponding lower guide grooves 5, allowing the lower transmission plate 71 to move smoothly upward until the mother mold body 74 approaches the sub-mold body 64. As the mother mold body 74 and the sub-mold body 64 move relative to each other, the positioning pin 66 at the lower end of the sub-mold body 64 is accurately inserted into the positioning hole 75 at the upper end of the mother mold body 74. At the same time, the sealing sleeve 65 is movably fitted inside the mother mold body 74, realizing the installation and positioning of the mother mold body 74 and the sub-mold body 64.
