Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a hydraulic mold clamping mechanism. Background Art

[0002] In the molding process, the mold is an important molding component. Generally, for each product, different molds need to be designed, which brings a certain cost to the design, development and production of the product. Therefore, there are molds with replaceable templates on the market. When changing the production plan, by removing and replacing the templates on the mold, different products can be produced on the same set of molds. Currently, for the above-mentioned molds with replaceable templates on the market, screw-type rotary fixing clamps are mostly used to fix the templates. Although the installation is firm, there are problems of inconvenient disassembly and assembly and slow disassembly and assembly speed. Therefore, the utility model provides a hydraulic mold clamping structure to solve the above technical problems. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model proposes a structure for quickly disassembling and assembling templates.

[0004] A hydraulic mold clamping mechanism includes a hydraulic lock. One end of the hydraulic lock is provided with a quick installation seat matching a T-shaped groove, and the other end is provided with a pressing member movably installed. The distance between the pressing end of the pressing member and the quick installation seat is the clamping distance for clamping the template. In order to provide a stable and reliable clamping force, a hydraulic method is adopted. Specifically, a hydraulic cylinder structure communicating with an external hydraulic pump is arranged in the hydraulic lock, including a floating hydraulic cavity and a piston rod. The floating hydraulic cavity is filled with oil through an external hydraulic pump. The piston rod moves under the action of the oil pressure and drives the pressing end of the pressing member to move towards the quick installation seat, thereby controlling the shortening of the clamping distance and forming a clamping force.

[0005] The hydraulic mold clamping mechanism provided by the utility model adopts a hydraulic lock with a hydraulic cylinder structure. When hydraulic pressure is input, it can actively control its pressing member to clamp the template. When the template needs to be removed, only the hydraulic pressure needs to be released, which can improve the convenience and speed of the template disassembly and assembly process, improve production efficiency, and reduce the operation difficulty and work burden of operators.

[0006] Preferably, the hydraulic mold clamping mechanism further includes a mold base and a template. The mold base is provided with the T-shaped groove. The hydraulic lock is quickly installed into the mold base through the end of the T-shaped groove, and the template is pressed on the mold base by the pressing member.

[0007] Preferably, the mold base includes an upper mold base and a lower mold base, and both the upper mold base and the lower mold base are provided with the T-shaped groove.

[0008] Preferably, the pressing member is telescopically installed, and the piston rod of the hydraulic cylinder structure can be directly utilized to streamline the mechanism.

[0009] Preferably, the floating hydraulic chamber is arranged inside the pressing member. The piston rod is a telescopic piston rod, one end of which is fixedly connected to the quick-loading seat, and the other end telescopically inserts into the floating hydraulic chamber of the pressing member. A through hole communicating with the floating hydraulic chamber is provided at one end of the pressing member close to the quick-loading seat. When an external hydraulic pump adds hydraulic oil into the floating hydraulic chamber through the through hole, the hydraulic oil pushes the piston head of the telescopic piston rod, so that the telescopic piston rod further enters the pressing member. At this time, the exposed part of the telescopic piston rod is shortened, and at the same time, the clamping distance is also shortened, and the pressing of the template can be realized.

[0010] Preferably, strip-shaped holes are provided on the periphery of the template, and the strip-shaped holes are aligned with the T-shaped grooves. After the quick-loading seat of the hydraulic lock is inserted into the T-shaped groove, the piston rod enters the strip-shaped holes, so that the contact area between the pressing member and the template is larger and the pressing state is more stable.

[0011] Preferably, the pressing member is installed in a lever manner, and the lever can be used to increase the clamping force.

[0012] Preferably, the floating hydraulic chamber is arranged inside the quick-loading seat, and mounting ears are provided at the end of the quick-loading seat. The pressing member is swingably installed at the mounting ears, one end is the pressing end, and the other end is the pushing end. The piston rod is a pushing piston rod, one end of which is arranged in the floating hydraulic chamber of the quick-loading seat, and the other end points to and abuts against the pushing end of the pressing member. A through hole communicating with the floating hydraulic chamber is provided at one end of the quick-loading seat far from the pressing member.

[0013] Preferably, a T-shaped guide block is provided at one end of the quick-loading seat far from the pressing member, and it can slide in the T-shaped groove.

[0014] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0015] The hydraulic mold locking mechanism provided by the present invention adopts a hydraulic lock with a hydraulic cylinder structure. When hydraulic pressure is input, it can actively control its pressing member to clamp the template. When the template needs to be removed, only the hydraulic pressure needs to be released, which can improve the convenience and speed of the template disassembly and assembly process, improve production efficiency, and reduce the operation difficulty and work burden of operators;

[0016] The pressing member is telescopically installed, and the piston rod of the hydraulic cylinder structure can be directly used, which simplifies the mechanism;

[0017] Strip-shaped holes are provided on the periphery of the template, and the strip-shaped holes are aligned with the T-shaped grooves. After the quick-loading seat of the hydraulic lock is inserted into the T-shaped groove, the piston rod enters the strip-shaped holes, so that the contact area between the pressing member and the template is larger and the pressing state is more stable;

[0018] The pressing member is installed in a lever manner, and the lever can be used to increase the clamping force to cope with templates of relatively large weight. Brief Description of the Drawings

Detailed implementation manners

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] Please refer to Figures 1 to 10 , a hydraulic locking die mechanism, including a hydraulic lock 1. One end of the hydraulic lock 1 is provided with a quick-mounting seat 11 matching a T-shaped groove 21, and the other end is provided with a pressing member 12 movably installed. The distance between the pressing end 121 of the pressing member 12 and the quick-mounting seat 11 is the clamping distance for clamping a template 3. In order to provide a stable and reliable clamping force, a hydraulic method is adopted. Specifically, a hydraulic cylinder structure communicating with an external hydraulic pump is provided in the hydraulic lock 1, including a floating hydraulic cavity and a piston rod. The floating hydraulic cavity is filled with oil through an external hydraulic pump. The piston rod moves under the action of oil pressure and drives the pressing end 121 of the pressing member 12 to move towards the quick-mounting seat 11, thereby controlling the shortening of the clamping distance and forming a clamping force.

[0034] It should be noted that the hydraulic cylinder structure is a mature existing technology, and the installation method between the floating hydraulic cavity and the piston rod will not be elaborated here.

[0035] In one embodiment, the hydraulic locking die mechanism further includes a die base 2 and a template 3. The die base 2 is provided with the T-shaped groove 21.

Preferably, the floating hydraulic cavity is arranged in the pressing member 12, the piston rod is a telescopic piston rod 13, one end is fixedly connected to the quick-mounting seat 11, and the other end telescopically inserts into the floating hydraulic cavity of the pressing member 12. A through hole communicating with the floating hydraulic cavity is provided at one end of the pressing member 12 close to the quick-mounting seat 11. When the external hydraulic pump adds oil into the floating hydraulic cavity through the through hole, the oil pushes the piston head of the telescopic piston rod 13, so that the telescopic piston rod 13 further enters the pressing member 12. At this time, the exposed part of the telescopic piston rod 13 shortens, and at the same time, the clamping distance also shortens, and the pressing of the template 3 can be realized.

[0037] In addition, strip-shaped holes 31 are provided in the peripheral part of the template 3, and the strip-shaped holes 31 are aligned with the T-shaped grooves 21. After the quick-installation seat 11 of the hydraulic lock 1 is inserted into the T-shaped grooves 21, the piston rod enters the strip-shaped holes 31, so that the contact area between the pressing member 12 and the template 3 is larger and the pressing state is more stable.

[0038] In another embodiment, the pressing member 12 is installed in a lever manner, and a lever can be used to increase the clamping force.

[0039] Preferably, the floating hydraulic chamber is arranged in the quick-installation seat 11, and installation ears 112 are provided at the end of the quick-installation seat 11. The pressing member 12 is swingably installed at the installation ears 112, with one end being the pressing end 121 and the other end being the pushing end 122.

[0040] The hydraulic lock 1 die mechanism provided by the present utility model adopts a hydraulic lock 1 with a hydraulic cylinder structure.

When the template 3 needs to be removed, only the hydraulic pressure needs to be released, which can improve the convenience and speed of the disassembly and assembly process of the template 3, improve production efficiency, and reduce the operation difficulty and work burden of the operator.
