Description

Technical Field

[0001] This utility model belongs to the technical field of injection molds, specifically relating to a split-type combined gantry mechanism for injection mold hydraulic cylinders. Background Technology

[0002] In injection mold design, the gantry serves as a support structure for the hydraulic cylinder. Its main function is to enhance the stability of the hydraulic cylinder, prevent excessive displacement or deformation of the hydraulic cylinder under thrust, and also to distribute the concentrated load of the hydraulic cylinder on the mold, protecting the mold structure from damage.

[0003] Existing gantry frames are monolithic structures, which have poor versatility and are difficult to install compatiblely with molds of different sizes. Furthermore, monolithic gantry frames have long processing cycles and require more materials, making it difficult to flexibly adapt them to different mold installation requirements and space constraints.

[0004] Therefore, in view of the above-mentioned defects of the existing integral gantry frame for injection molds, this utility model discloses a gantry frame mechanism with separate hydraulic cylinders for injection molds. Utility Model Content

[0005] This utility model discloses a split-type combined gantry mechanism for injection mold hydraulic cylinders. It adopts a split-type flexible assembly structure to form a stable gantry structure, which can be flexibly assembled and adapted to the installation needs and space requirements of different molds, further saving costs while improving the compatibility and convenience of the gantry.

[0006] This utility model is achieved through the following technical solution:

[0007] A split-type gantry mechanism for injection mold hydraulic cylinders includes a central support and side supports. The central support has symmetrically arranged engaging protrusions on its left and right sides. The top of each side support, near the central support, has a slot that engages with the engaging protrusions. Fasteners connect the slots and engaging protrusions. An adapter is mounted in the middle of the central support, and a hydraulic cylinder is located at the bottom of the adapter. The push rod end of the hydraulic cylinder is connected to the bottom of the adapter via an anti-rotation component.

[0008] The side supports can be easily installed on both sides of the central support through the engaging connection between the slot and the engaging protrusion, forming a split gantry structure. Fasteners further connect the central support and the side supports, ensuring the stability of the entire gantry structure. An adapter is fitted in the middle of the central support; the top of the adapter engages with the middle of the central support, and the bottom of the adapter connects to the end of the hydraulic cylinder's push rod via an anti-rotation component. The hydraulic cylinder push rod extends to lift the central support, which connects to the injection mold, thereby opening the mold.

[0009] To better realize this utility model, a horizontal connecting screw is further provided between the slot and the engaging protrusion. The horizontal connecting screw passes through the side bracket and is threadedly connected to one side of the engaging protrusion. A bracket screw passes through the top to the bottom of the side bracket.

[0010] To better realize this utility model, the adapter further includes an adapter block, an adapter hole is provided at the middle position of the central support, the adapter block is inserted into the adapter hole, and an anti-rotation component is provided between the top of the adapter block and the top surface of the central support.

[0011] To better realize this utility model, the anti-rotation component further includes an anti-rotation block, which is fixed to one side of the top surface of the adapter hole by connecting screws. An anti-rotation plane is provided on one side of the adapter block, and the anti-rotation plane abuts against one side of the anti-rotation block.

[0012] To better realize this utility model, the anti-rotation component further includes an L-shaped anti-rotation block and an anti-rotation screw. The vertical section of the L-shaped anti-rotation block is fixedly connected to one side of the bottom of the adapter through the anti-rotation screw, and the horizontal section of the L-shaped anti-rotation block is circumferentially engaged with one side of the push rod end of the oil cylinder.

[0013] To better realize this utility model, the push rod end of the oil cylinder is further provided with an anti-rotation groove on one side, and the horizontal section of the L-shaped anti-rotation block extends into the anti-rotation groove and is circumferentially engaged with the anti-rotation groove.

[0014] To better realize this utility model, furthermore, cylinder screws are symmetrically inserted on the left and right sides of the cylinder body.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] This utility model features a split gantry structure formed by the corresponding interlocking and splicing of the central support and side supports. This ensures stable support for the hydraulic cylinder while allowing for flexible installation to adapt to the different installation needs and space requirements of various molds. This makes the installation and use of the gantry more convenient, reduces operating costs, and enhances compatibility. Attached Figure Description

Detailed Implementation

[0023] Example 1:

[0024] This embodiment describes a split-type combined gantry mechanism for injection mold hydraulic cylinders, such as... Figures 1-4 As shown, the device includes a central support 1 and side supports 2. The central support 1 has symmetrically arranged engaging protrusions 11 on its left and right sides. The side supports 2 have a slot 21 on the top side near the central support 1. The slot 21 and the engaging protrusions 11 are engaged and connected by fasteners. An adapter is installed in the middle of the central support 1. A hydraulic cylinder 3 is installed at the bottom of the adapter. The push rod end of the hydraulic cylinder 3 is connected to the bottom of the adapter through an anti-rotation component.

[0025] The central support 1, serving as the main load-bearing component, is installed between the side supports 2 on both the left and right sides. The bottom of the side supports 2 is connected to the mold pin plate, and the top of the side supports 2, near the central support 1, is engaged with the engaging protrusions 11 on both sides of the central support 1 via a slot 21. The central support 1 and the side supports 2, configured in a split-type engaging manner, form a combined gantry structure. An adapter is installed in the middle of the central support 1, which is connected to the push rod end of the hydraulic cylinder 3. The push rod of the hydraulic cylinder 3 pushes the central support 1, thereby moving the injection mold connected to the central support 1 to achieve mold closing or opening.

[0026] Depending on the spatial dimensions required by different molds, the central support 1 of different specifications can be flexibly replaced to meet the installation requirements of different molds. At the same time, the split-type snap-fit ​​connection between the central support 1 and the side support 2 is easier to process and saves more materials compared to the existing integral gantry frame.

[0027] Example 2:

[0028] This embodiment is a further optimization based on Embodiment 1, such as... Figure 1 , Figure 3 As shown, a horizontal connecting screw 4 is provided between the slot 21 and the engaging protrusion 11. The horizontal connecting screw 4 passes through the side bracket 2 and is threadedly connected to one side of the engaging protrusion 11. A bracket screw 5 is provided between the top and bottom of the side bracket 2.

[0029] To further ensure the stability of the connection between the central support 1 and the side support 2, a stepped hole is provided horizontally through the side support 2, and a horizontal threaded hole is provided on the engaging protrusion 11. The horizontal connecting screw 4 is passed through the stepped hole, and the threaded section of the horizontal connecting screw 4 is engaged with the threaded hole, thereby ensuring a stable engagement between the slot 21 and the engaging protrusion 11, thus ensuring the stability of the entire gantry frame. At the same time, a vertical hole is provided between the top and bottom of the side support 2, and a support screw 5 is installed in the vertical hole. The support screw 5 passes through the vertical hole and connects to the mold pin plate to achieve the installation and fixation of the side support 2.

[0030] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0031] Example 3:

[0032] This embodiment is a further optimization based on the above embodiment 1 or 2, such as... Figure 1 and Figure 5 As shown, the adapter includes an adapter block 6, and an adapter hole is provided at the middle position of the central support 1. The adapter block 6 is inserted into the adapter hole, and an anti-rotation component is provided between the top of the adapter block 6 and the top surface of the central support 1.

[0033] The adapter block 6 has flanges at both its top and bottom ends. These flanges engage with the top or bottom face of the adapter hole, allowing the adapter block 6 to move the central support 1. By setting an anti-rotation component to circumferentially engage and limit the adapter block 6, its circumferential rotation is restricted, ensuring that the adapter block 6 can only be lifted or lowered vertically under the drive of the hydraulic cylinder 3, and cannot rotate circumferentially.

[0034] Furthermore, the anti-rotation component includes an anti-rotation block 7, which is fixed to one side of the top surface of the adapter hole by connecting screws. One side of the adapter block 6 is provided with an anti-rotation plane, which abuts against one side of the anti-rotation block 7. Through the abutment between one side of the anti-rotation block 7 and the anti-rotation plane of the adapter block 6, the circumferential rotation of the adapter block 6 is restricted.

[0035] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.

[0036] Example 4:

[0037] This embodiment is a further optimization based on any one of embodiments 1-3 above, such as... Figure 1 , Figure 5 As shown, the anti-rotation component includes an L-shaped anti-rotation block 8 and an anti-rotation screw 9. The vertical section of the L-shaped anti-rotation block 8 is fixedly connected to the bottom side of the adapter through the anti-rotation screw 9, and the horizontal section of the L-shaped anti-rotation block 8 is circumferentially engaged with one side of the push rod end of the oil cylinder 3.

[0038] A threaded hole is provided on one side of the bottom of the adapter. The anti-rotation screw 9 passes through the vertical section of the L-shaped anti-rotation block 8 and connects to the threaded hole to fix the L-shaped anti-rotation block 8 to the bottom of the adapter. The horizontal section of the L-shaped anti-rotation block 8 is engaged with one side of the push rod end of the hydraulic cylinder 3 to restrict the circumferential rotation of the push rod of the hydraulic cylinder 3 and ensure that the push rod of the hydraulic cylinder 3 moves axially.

[0039] Furthermore, an anti-rotation groove is provided on one side of the push rod end of the hydraulic cylinder 3, and the horizontal section of the L-shaped anti-rotation block 8 extends into the anti-rotation groove and engages circumferentially with it. By engaging the horizontal section of the L-shaped anti-rotation block 8 with the anti-rotation groove, the circumferential rotation of the push rod of the hydraulic cylinder 3 is limited, restricting the circumferential rotation of the push rod without affecting its axial movement.

[0040] Furthermore, cylinder screws 10 are symmetrically installed on the left and right sides of the cylinder body of the cylinder 3. The cylinder screws 10 pass through the mounting holes on the left and right sides of the cylinder body of the cylinder 3 and are connected to the mold pin plate to realize the installation and fixation of the cylinder 3.

[0041] The other parts of this embodiment are the same as any one of the embodiments 1-3 above, so they will not be described again.

[0042] 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 way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
