Description

Technical Field

[0001] The utility model relates to the technical field of split hot runner, in particular to a split hot runner disassembly and assembly structure and a split hot runner system. Background Art

[0002] The hot runner system is widely used in the production of injection molds. The split hot runner system is more widely used due to its convenient installation and modification, simple modification, convenient maintenance and relatively low price. The manifold plate and the main body of the split hot runner system are separated. During assembly, it is installed in the installation groove on the hot runner plate through the main body. The existing operation position on the structure is that there are 2 process threads machined on the top surface provided with the runner. The machining of the threads is more cumbersome than that of the card slot, and the assembly and disassembly are also more cumbersome. It is necessary to screw the fixture with threads onto the main body and then lift it by hoisting. The operation of the staff is troublesome. When the system needs to be repaired due to reasons such as glue leakage, after the molten plastic enters the process thread and solidifies, it is inconvenient to clean and cannot be completely cleaned, which affects injection molding, the repair efficiency is low, and it is not conducive to production.

[0003] Therefore, there is an urgent need for a split hot runner disassembly and assembly structure and a split hot runner system to solve the problem of complex operation during assembly and disassembly. Summary of the Utility Model

[0008] A second main body, which is connected to one side of the first main body along the axial direction, and the second main body can be inserted into the installation hole of the base.

[0009] Preferably, at least two hoisting holes are arranged.

[0010] Preferably, at least two of the hoisting holes are evenly and spaced along the circumferential direction of the first main body.

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0031] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above the", and "on the" second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below the", and "under the" second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature has a lower horizontal height than the second feature.

[0033] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] In this embodiment, a split hot runner disassembly and assembly structure is provided. As Figure 1 and Figure 2 shown, a runner group 30 is arranged along the axial direction of the structure, and the colloid can flow into the runner group 30 to complete the injection of the colloid. The structure includes a first main body 10 and a second main body 20. The runner plate can abut against the top end of the first main body 10. A hoisting hole 11 is arranged radially on the side wall of the first main body 10, and a hoisting tool can be connected to the hoisting hole 11 to hoist the first main body 10; the second main body 20 is connected to one side of the first main body 10 along the axial direction, and the second main body 20 can be inserted into the installation hole 41 of the base 40.

[0035] In this structure, the hoisting hole 11 is arranged on the side wall of the first main body 10 instead of on the top surface of the first main body 10. This not only facilitates hoisting with a hoisting tool, but also can conveniently place the second main body 20 in the installation hole 41. At the same time, it can also separate the hoisting hole 11 from the runner group 30, facilitating the docking of the hot runner hole of the runner plate with the runner group 30, and avoiding the situation where the hot runner hole is communicated with the hoisting hole 11, resulting in the problem that the colloid cannot be injected smoothly; in addition, setting the hoisting hole 11 on the side wall instead of the top surface can also prevent the colloid from flowing into the hoisting hole 11 after overflowing from the connection between the runner plate and the runner group 30, thereby avoiding the problem that the hoisting tool cannot smoothly extend into the hoisting hole 11. In addition, when disassembly is required, only the runner plate needs to be removed, the hoisting tool is connected to the hoisting hole 11 again, and it can be taken out from the installation hole 41, and the operation is simple and convenient.

[0036] To ensure the stability of hoisting, at least two hoisting holes 11 are arranged on the first main body 10. By setting more than two hoisting holes 11, it can be ensured that the structure will not fall during the hoisting process, effectively avoiding the problems of injuring the staff and the structure being damaged.

[0037] In addition, at least two hoisting holes 11 are evenly and spaced along the axial direction of the first main body 10. This setting can ensure that the main body of the structure will not tilt to one side during the hoisting and handling process, thereby further ensuring the stability during the handling process and facilitating installation. It should be noted here that the hoisting tool can be any one of a claw jig and a hook, and no specific limitation is made in this embodiment.

[0038] As Figure 1and Figure 2 As shown, the hoisting hole 11 is an elongated hole. The elongated hole can not only improve the structural strength, facilitate assembly and maintenance, but also has no threads inside. Even if the colloid leaks out from the connection between the manifold plate and the runner group 30 and flows along the side wall of the first body 10 into the elongated hole, it can be quickly removed from the elongated hole, and there will be no situation where the colloid adheres to the thread gaps, which is convenient for cleaning. And to further ensure that the colloid does not easily enter the elongated hole, the hoisting hole 11 is not radially connected to the runner group 30 along the first body 10; this setting can ensure that the colloid only flows within the runner group 30, thus ensuring a good glue discharging effect.

[0039] It should be noted here that in this embodiment, the depth of the elongated hole along the radial direction of the first body 10 is 2 mm - 4 mm, the width between the two elongated parts is 3 mm - 5 mm, and the height between the two arc-shaped parts of the elongated hole is 6 mm - 8 mm, so as to facilitate hoisting. In other embodiments, the size of the elongated hole can be changed according to actual requirements and the types of lifting tools. In this embodiment, the size of the elongated hole is not specifically limited, as long as it is convenient to use and not connected to the runner group 30.

[0040] As Figure 1 and Figure 2 shown, the first body 10 and the second body 20 are coaxially arranged. This structure is not only convenient for processing, but also convenient for installation, ensuring the convenience of disassembly and assembly.

[0041] This embodiment also provides a split type hot runner system, which includes a manifold plate, a base 40 and a split type hot runner disassembly and assembly structure. The manifold plate abuts against the first body 10 and is connected to the runner group 30. The second body 20 is inserted into the installation hole 41 of the base 40, and the bottom end of the first body 10 can abut against the base 40. Applying the above split type hot runner disassembly and assembly structure, this split type hot runner system can ensure good injection molding efficiency while being convenient for assembly.

[0042] As Figure 1 and Figure 2As shown, the base 40 is provided with 43 placement grooves and positioning grooves 42 connected in sequence along the vertical direction, and the positioning grooves 42 are connected to the mounting hole 41. When the second body 20 is plugged into the mounting hole 41, the positioning grooves 42 can accommodate the first body 10. This arrangement can ensure the radial stability of the first body 10, so that the colloid can flow smoothly into the runner group 30, ensuring a good injection molding effect. It should be noted here that the diameter of the placement groove 43 is larger than the diameter of the positioning groove 42, so that the first body 10 can be placed and removed conveniently. The diameter of the positioning groove 42 is equivalent to the diameter of the first body 10, that is, the first body 10 can be just accommodated in the positioning groove 42, and the outer wall of the first body 10 and the inner wall of the positioning groove 42 are mutually fitted and abutted, thereby ensuring the radial stability of the first body 10, and will not limit the sling to assemble the first body 10 in the positioning groove 42 through the lifting hole 11, or take it out of the positioning groove 42, thereby ensuring the convenience of assembly and disassembly.

[0043] In addition, the diameter of the second body 20 is smaller than the inner diameter of the mounting hole 41, and the diameter of the mounting hole 41 is smaller than the diameter of the first body 10. This arrangement can ensure that a reserved gap is formed between the second body 20 and the inner wall of the mounting hole 41, which can effectively prevent the rapid loss of heat, thereby producing a good thermal insulation effect and preventing the colloid from solidifying; the diameter of the first body 10 is larger than the diameter of the mounting hole 41, which can ensure that the bottom end surface of the first body 10 abuts against the top end surface of the base 40, and the first body 10 will not enter the mounting hole 41, thereby facilitating the connection of the sling to the hoisting hole 11, thereby facilitating the removal of the structural body, and ensuring the convenience of use.

[0044] like Figure 1 As shown, a positioning piece (not shown in the figure) is also provided in the positioning groove 42, and a positioning hole 12 is radially provided on the side wall of the first body 10, and the positioning piece can be snapped into the positioning hole 12 so that the split hot runner assembly and disassembly structure cannot rotate around its axis. When the split hot runner assembly and disassembly structure of the sling is hoisted into the mounting hole 41, the positioning piece can be aligned with the positioning hole 12, so that the split hot runner assembly and disassembly structure can be installed in a preset position, and after the positioning piece is inserted into the positioning hole 12, the split hot runner assembly and disassembly structure cannot rotate around its axis (it will not be separated from the positioning groove 42 and the mounting hole 41 along its axial direction), thereby ensuring that the hot runner hole on the manifold plate is aligned with the manifold group 30, so that the glue can be discharged normally and injection molding can be performed.

[0045] In summary, the use of the split hot runner disassembly and assembly structure and the split hot runner system in this embodiment can not only solve the problem of inconvenient assembly and disassembly, but also ensure a good injection molding effect.

[0046] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
