Description

Technical Field

[0001] This utility model relates to the field of hydraulic mold clamping technology, specifically a hydraulic mold clamping device for injection molds. Background Technology

[0002] Hydraulic mold clamping is a method used to fix molds on injection molding machines. It uses a hydraulic system to provide pressure to ensure the stability and precision of the mold during the injection process.

[0003] Existing mold clamping devices have pressure plates that are in direct contact with the injection mold. In high-temperature operating environments, the mold heat is easily conducted to the pressure plates and clamping devices, affecting the service life of the pressure plates and even causing deformation. Regular maintenance and replacement of the pressure plates are required to ensure stability. However, the existing clamping devices generally use bolts to directly lock the pressure plates. When the mold is working, the gap between the hydraulic cylinder and the pressure plate is often a problem, making bolt disassembly inconvenient and time-consuming. Therefore, a hydraulic mold clamping device for injection molds that facilitates the disassembly of the pressure plates is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic mold clamping device for injection molds, so as to solve the above-mentioned technical problems to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a clamping body, a clamping template disposed on the protruding part of the clamping body for rotation, a first limiting head and a second limiting head respectively inserted into the two protruding parts of the clamping body, a first connecting rod with one end inserted into the clamping template being horizontally fixedly disposed on the inner surface of the first limiting head, a second connecting rod with one end inserted into the clamping template being horizontally fixedly disposed on the inner surface of the second limiting head, a fixing head being fixedly disposed on the inner end of the first connecting rod, and two symmetrical locking blocks being disposed on the outer wall of the fixing head, one end of the fixing head being inserted into and constrained to be fixed inside the second connecting rod;

[0006] A disassembly head is fitted to the outer surface of the first limiting head. A moving rod with one end inserted into the inside of the first limiting head is fixedly arranged on the inner surface of the disassembly head. A reset component for pushing the disassembly head to reset is provided inside the first limiting head. Positioning plates inserted into the protruding part of the mold clamp body are respectively provided on the outer walls of the second limiting head and the disassembly head.

[0007] Preferably, the reset assembly includes a guide block slidably disposed inside the first limiting head and fixedly connected at one end to the outer wall of the moving rod, and a reset spring sleeved on the outer wall of the moving rod and in contact with the guide block at one end.

[0008] Preferably, the outer surface of the first limiting head is provided with a mounting hole for installing the moving rod, and the inner wall of the first limiting head is provided with two guide grooves, and one end of each of the two guide blocks is respectively inserted into the two guide grooves.

[0009] Preferably, the outer wall of the disassembly head is provided with a pull ring, and the two sides of the protruding part of the clamping body are respectively provided with positioning grooves that match the positioning plates, and one side of each of the multiple positioning plates is inserted into the multiple positioning grooves.

[0010] Preferably, the inner wall of the second connecting rod has two horizontally formed mounting grooves that match the locking block, and the lower part of the inner wall of the second connecting rod has an annular groove that communicates with the mounting grooves. One end of the locking block is rotated into the annular groove through the mounting groove.

[0011] Preferably, through holes are provided on both sides of the outer wall of the clamping template, and one end of the first connecting rod and the second connecting rod are respectively inserted into the interior of the clamping template through the through holes.

[0012] Preferably, when the positioning plate is located in the positioning groove, the locking block is disengaged from the mounting groove and located in the annular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, pulling the pull ring outward causes the two positioning plates on the outer wall of the disassembly head to disengage from the interior of the protruding part of the clamping body. Then, the disassembly head can be rotated, causing the connected moving rod to drive the first limiting head to rotate. This causes one end of the first connecting rod to rotate inside the second connecting rod. During rotation, it is pulled outward slightly. When the locking block rotates to the corresponding position of the mounting groove, the locking block disengages through the mounting groove, causing the fixing head to disengage from the interior of the second connecting rod, thus completing the disassembly and disassembly between the first connecting rod and the second connecting rod. This facilitates the removal, replacement, and maintenance of the clamping template from the clamping body. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a hydraulic mold clamping device for injection molds, including a clamping device body 1, a clamping template 2 that is rotated on the protrusion of the clamping device body 1, a first limiting head 3 and a second limiting head 4 respectively inserted into the two protrusions of the clamping device body 1, a first connecting rod 31 with one end inserted into the inside of the clamping template 2 is horizontally fixed on the inner surface of the first limiting head 3, a second connecting rod 41 with one end inserted into the inside of the clamping template 2 is horizontally fixed on the inner surface of the second limiting head 4, a fixing head 311 is fixedly fixed at the inner end of the first connecting rod 31, and two symmetrical locking blocks 312 are provided on the outer wall of the fixing head 311. One end of the fixing head 311 is inserted into and constrained to the locking block 312 respectively inside the second connecting rod 41.

[0025] The outer surface of the first limiting head 3 is fitted with a disassembly head 5. The inner surface of the disassembly head 5 is laterally fixed with a moving rod 52, one end of which is inserted into the first limiting head 3. The first limiting head 3 is equipped with a reset component 7 for pushing the disassembly head 5 to reset. The outer walls of the second limiting head 4 and the disassembly head 5 are respectively equipped with positioning plates 6 that are inserted into the protruding part of the clamping body 1.

[0026] When it is necessary to remove the clamping template 2 from the clamping body 1, pull the pull ring 51 outward. The pull ring 51 drives the connected disassembly head 5 and the moving rod 52 located inside the first limiting head 3 to move outward. The guide block 71 on the outer wall of the moving rod 52 pushes the return spring 72 to press together, so that the two positioning plates 6 on the outer wall of the disassembly head 5 disengage from the inside of the protruding part of the clamping body 1. Then, the disassembly head 5 can be rotated so that the connected moving rod 52 drives the first limiting head 3 to rotate, so that the first connecting rod connected to the first limiting head 3 can rotate. One end of rod 31 rotates inside the second connecting rod 41, and is pulled slightly outward during rotation. When the locking block 312 inside the second connecting rod 41 rotates to face the inner end of the mounting groove 411, the locking block 312 disengages through the transverse mounting groove 411, allowing the fixing head 311 to disengage from the inside of the second connecting rod 41, thus completing the disengagement and disassembly of the first connecting rod 31 and the second connecting rod 41. This allows the first connecting rod 31 and the second connecting rod 41 to be disengaged from the clamping template 2, making it easier to remove the clamping template 2 from the clamping device body 1 for replacement and maintenance.

[0027] More preferably, the reset assembly 7 includes a guide block 71 that is slidably disposed inside the first limiting head 3 and fixedly connected at one end to the outer wall of the moving rod 52, and a reset spring 72 that is sleeved on the outer wall of the moving rod 52 and at one end contacts the guide block 71.

[0028] By sliding a guide block 71 with one end fixedly connected to the moving rod 52 inside the first limiting head 3, when the moving rod 52 moves outward, the guide block 71 pushes the reset spring 72 to press together. When the installation is completed, the release pull is pushed by the reset spring 72 to reset the disassembly head 5, so that the positioning plate 6 is inserted into the edge of the protruding part of the mold clamp body 1 to limit the first limiting head 3.

[0029] More preferably, the outer surface of the first limiting head 3 is provided with a mounting hole for mounting the moving rod 52, and the inner wall of the first limiting head 3 is provided with two guide grooves, and one end of each of the two guide blocks 71 is inserted into the two guide grooves respectively;

[0030] The mounting hole on the outer surface of the first limiting head 3 is used to insert one end of the moving rod 52 into its interior, and the two guide grooves on the inner wall of the first limiting head 3 are used to insert the guide block 71 into its interior for limiting movement.

[0031] In a further preferred embodiment, the outer wall of the disassembly head 5 is provided with a pull ring 51, and the two sides of the protruding part of the clamping body 1 are respectively provided with positioning grooves that match the positioning plates 6, and one side of each of the multiple positioning plates 6 is inserted into the multiple positioning grooves.

[0032] The pull ring 51 on the outer wall of the disassembly head 5 makes it easy to pull the disassembly head 5. The positioning groove opened on the protruding part of the mold clamping body 1 matches the positioning plate 6, so that the positioning plate 6 can be inserted into the inside of the protruding part of the mold clamping body 1 when it is reset.

[0033] More preferably, the inner wall of the second connecting rod 41 has two horizontally formed mounting grooves 411 that match the locking block 312, and the lower part of the inner wall of the second connecting rod 41 has an annular groove 412 that communicates with the mounting grooves 411. One end of the locking block 312 rotates into the annular groove 412 through the mounting grooves 411.

[0034] The second connecting rod 41 has an installation groove 411 on its inner wall that matches the locking block 312. When the moving rod 52 is installed into the second connecting rod 41, the locking block 312 moves through the installation groove 411 into the annular groove 412 on the inside. Then, the locking block 312 is rotated so that it is located in the annular groove 412, thus constraining and fixing the locking block 312 inside the second connecting rod 41.

[0035] More preferably, through holes 21 are provided on both sides of the outer wall of the clamping template 2, and one end of the first connecting rod 31 and the second connecting rod 41 are respectively inserted into the interior of the clamping template 2 through the through holes 21;

[0036] The clamping template 2 is rotated on the outer wall of the first connecting rod 31 and the second connecting rod 41 through the through hole 21 on the outer wall.

[0037] More preferably, when the positioning plate 6 is located in the positioning groove, the locking block 312 is disengaged from the mounting groove 411 and located in the annular groove 412.

[0038] A specific application of this embodiment is as follows: When installing the clamping template 2, first place the clamping template 2 in the middle of the protruding part of the clamping body 1, align the through hole 21 of the clamping template 2 with the hole of the protruding part, insert one end of the second connecting rod 41 through the hole of the protruding part of the clamping body 1 and into the clamping template 2, insert the second limiting head 4 and the positioning plate 6 into the interior of the protruding part of the clamping body 1 and prevent them from rotating, when installing the first connecting rod 31, pull the pull ring 51 to expose a gap between the disassembly head 5 and the first limiting head 3, use a tool to insert into the gap, insert one end of the first connecting rod 31 into the clamping template 2, and set a mark on the protruding part of the clamping body 1 on the disassembly head 5 respectively. When the two marks are aligned, the locking block 312 is aligned with the mounting groove 411. At this time, the positioning plate 6 on the disassembly head 5 is not aligned with the positioning groove. Part of the first limiting head 3 is exposed from the protrusion of the clamping body 1. One hand pulls the pull ring 51 and uses a tool inserted into the gap, such as a screwdriver, a thin iron roller, or a thin, hard tool, to push the first limiting head 3 inward, so that the fixing head 311 and the locking block 312 are inserted into the second connecting rod 41. When the first limiting head 3 moves to the point where it cannot be pushed, the other hand rotates the pull ring 51 to make the locking block 312 disengage from the mounting groove 411 and move into the annular groove 412, thus completing the fixation between the first connecting rod 31 and the second connecting rod 41.
