Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial equipment technology, specifically to a mold assembly device for injection molding machines. Background Art
[0002] Injection molding machines, as essential equipment in modern industrial production, inject molten plastic into a mold under high pressure, allowing it to cool and form the desired product. They are widely used in various manufacturing fields. Injection molding machines not only improve production efficiency and reduce costs but also ensure product quality, making them an indispensable part of modern industrial production. However, in current injection molding technology, mold installation typically relies on overhead cranes (or gantry cranes). This installation method is common in large injection molding workshops, where the mold is lifted by the overhead crane and transported to the injection molding machine, where workers then manually install it. However, small factories often have limited space, making it impossible to install large overhead cranes. Overhead cranes require not only sufficient space to operate but also a stable support structure to ensure safety during lifting. In small factories, the limited space often makes it difficult to provide enough space for installing and maintaining overhead cranes. This not only limits mold installation efficiency but also increases operational difficulty and safety hazards.
[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0026] like Figures 1 to 4As shown, an injection molding machine for easy mold replacement is used to assemble mold 11. It includes an injection molding machine housing 1 with an assembly plate 2, a positioning plate 3 with a limit block 8 at one end of the assembly plate 2, an upper limit post 32 and a lower limit post 31 between the assembly plate 2 and the positioning plate 3, a baffle 5 at the top of one side of the positioning plate 3, a first support plate 6 at the bottom of one side of the positioning plate 3, and a second support plate 7 on one side of the assembly plate 2. The baffle 5 has a rectangular cross-section, a gap exists between the upper limit post 32 and the lower limit post 31, the first support plate 6 and the second support plate 7 are symmetrically arranged, and one end of the baffle 5 has a limit block 8. The positioning hook 9 has an arc surface 10 on one side. In this utility model, the mold 11 enters the embodiment through the gap between the upper positioning post 32 and the lower positioning post 31 and is located between the assembly plate 2 and the positioning plate 3. One side of the mold 11 is limited and hooked by the positioning hook 9. The bottom end of the mold 11 abuts against the first support plate 6 and the second support plate 7 respectively. By setting the positioning hook 9 on the positioning plate 3, one end of the mold 11 can be limited by the positioning hook 9 to prevent the mold 11 from falling off between the assembly plate 2 and the positioning plate 3. Furthermore, by setting the baffle 5, the mold 11 is prevented from being pushed in excessively and from falling off from the other end.
[0027] The upper limit post 32 has a circular cross-sectional shape. The upper limit post 32 and the lower limit post 31 have the same shape and structure. Both the lower limit post 31 and the upper limit post 32 are fixedly connected to the positioning plate 3. The four corners of the assembly plate 2 are respectively provided with openings 21 for the lower limit post 31 and the upper limit post 32 to pass through. The openings 21 allow the upper limit post 32 and the lower limit post 31 to be movably connected to the positioning plate 3. It is worth noting that in this embodiment, there are at least two upper limit posts 32, at least two lower limit posts 31, and at least four openings 21 on the assembly plate 2. The positioning plate 3 changes the distance between itself and the assembly plate 2 through the upper limit post 32 and the lower limit post 31, which facilitates the clamping and assembly of the mold 11 between the assembly plate 2 and the positioning plate 3, and further prevents the mold 11 from falling off.
[0028] Furthermore, one end of the assembly plate 2 is mechanically connected to a first sub-support plate 22, one side of which is flush with one side of the assembly plate 2. One end of the first sub-support plate 22 has a first trapezoidal protrusion 23, and one side of the first sub-support plate 22 has a first inclined surface 36. One end of the positioning plate 3 has a second sub-support plate 33, one side of which is flush with one side of the positioning plate 3. The first sub-support plate 22 and the second sub-support plate 33 are arranged opposite to each other and parallel to each other. The cross-sectional shape of both the first sub-support plate 22 and the second sub-support plate 33 is L-shaped. One end of the second sub-support plate 33 has a... The positioning plate 3 has a second trapezoidal protrusion 34 and a second inclined surface 35 on one side. By setting the first sub-plate 22 and the second sub-plate 33, the user can abut the mold 11 against the first sub-plate 22 and the second sub-plate 33 and push it between the assembly plate 2 and the positioning plate 3. Due to the setting of the first inclined surface 36 and the second inclined surface 35, the distance between the first sub-plate 22 and the second sub-plate 33 is increased to a figure-eight shape. After the user adjusts the distance between the assembly plate 2 and the positioning plate 3, it is easy to push the mold 11 in.
[0029] It should be noted that the top surface of the first trapezoidal protrusion 23 and the top surface of the second trapezoidal protrusion 34 are located in the same plane, and the top surface of the first trapezoidal protrusion 23 and the top surface of the first support plate 6 are located in the same plane, and the top surface of the second trapezoidal protrusion 34 and the top surface of the second support plate 7 are located in the same plane. In this embodiment, the user needs to transport the mold 11 to the injection molding machine by means of a hydraulic pallet trolley, and after raising the mold 11 to the position of the first sub-support plate 22 and the second sub-support plate 33, push the mold 11 between the assembly plate 2 and the positioning plate 3. Through the first trapezoidal protrusion 23 and the second trapezoidal protrusion 34, there are inclined surfaces on the first sub-support plate 22 and the second sub-support plate 33, which further facilitates the user to push the mold 11 between the assembly plate 2 and the positioning plate 3. After the mold is assembled, the hydraulic pallet trolley is pushed away.
[0030] It should be further explained that one end of the assembly plate 2 is provided with a fixing plate 24, and one end of the fixing plate 24 is provided with a positioning hook groove 25; by setting the positioning hook groove 25, the mold 11 can be pushed into this embodiment through the positioning hook groove 25, which makes it convenient for the user to position the assembly position of the mold 11 and facilitates the installation of the mold 11.
[0031] In this embodiment, to further optimize the embodiment and facilitate the user to fix the mold 11 on the injection molding machine housing 1, both the assembly plate 2 and the positioning plate 3 are provided with several openings. The mold 11 is provided with screw holes that cooperate and communicate with the openings. After the user pushes the mold 11 onto the first support plate 6 and the second support plate 7, the openings are aligned with the screw holes. Screws are used to pass through the openings and screw into the screw holes, so that one side of the mold 11 is screwed to the assembly plate 2 and the other side of the mold 11 is screwed to the positioning plate 3.
[0032] Working principle: The hydraulic pallet trolley transports the mold 11 to the side of the injection molding machine where the assembly plate 2 is located. The hydraulic pallet trolley raises the mold 11 to the position of the first pallet 6. The user pushes the mold 11 horizontally along the positioning hook groove 25, so that the bottom end of the mold 11 abuts against the first pallet 6 and the second pallet 7 respectively, and the upper end face of the mold 11 is hooked by the limiting hook 9 until one side of the mold 11 abuts against the baffle 5. After the assembly is completed, the hydraulic pallet trolley is pushed away.
