Description

Technical Field

[0001] The present application relates to the technical field of molding injection molds, and in particular to a stack mold support structure and a molding stack mold. Background Art

[0002] The stack mold (i.e., stack mold) is a cutting-edge technology in the development of plastic molds today. Its cavities are distributed on two or more levels and are arranged in an overlapping manner. The stack mold can mold multiple products at the same time. It is a new type of injection mold that is efficient, fast, and energy-saving. It is most suitable for molding large flat parts, shallow cavity shell parts, small multi-cavity thin-walled parts, and parts that need to be produced in large quantities.

[0003] Among them, the two-layer stacked mold with one mold and two cavities is the most common stacked mold. Its basic components include three independent parts: a fixed core template, a movable core template and an intermediate movable template. The fixed core template is fixed to the fixed template of the injection molding machine by a locking module, and the movable core template is fixed to the movable template of the injection molding machine by a locking module. The intermediate movable template is located between the fixed core template and the movable core template. Therefore, the intermediate movable template needs to be supported with sufficient strength to bear its entire weight, and at the same time, the support is required to have high precision to keep the mold accurately positioned.

[0004] Most of the existing stacking molds support the weight of the middle movable template by adding support devices on both sides of the mold, or directly hang the two sides of the middle movable template on the two sides of the Green column under the machine to support the middle movable module. During the production process, the fixed core template, the movable core template and the middle movable template are operated at the same time. There is a risk of the middle movable module falling and unstable product grasping when it is operated for a long time.

[0005] Therefore, how to provide a stack mold support structure that can effectively support the middle movable module of the stack mold and prevent it from falling is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the present application provides a stack mold support structure and a molding stack mold, which can effectively support the middle movable module of the stack mold to prevent it from falling, thereby improving the operating stability of the molding stack mold.

[0007] The technical solutions provided by this application are as follows:

[0008] A stack mold support structure includes a base plate, and sliding feet are respectively provided on both sides of the bottom of the base plate. The sliding feet on both sides are respectively slidably set on corresponding slide rails.

[0030] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the effects and purposes that can be achieved by this application.

[0031] For the convenience of description, in this application, the direction perpendicular to the slide rail 10 is taken as the length direction of the base plate 1, the positioning plate 2, and the support plate 7, and the direction extending along the slide rail 10 is taken as the width direction of the base plate 1, the positioning plate 2, and the support plate 7.

[0032] like Figure 1 and 2 As shown, an embodiment of the present application provides a stack mold support structure, including a base plate 1, wherein sliding feet 9 are respectively provided on both sides of the bottom of the base plate 1, and the sliding feet 9 on both sides are respectively slidably set on corresponding slide rails 10, and a positioning plate 2 is fixedly provided on the base plate 1, and the positioning plate 2 is used to support the middle movable module 11 of the forming stack mold, and a positioning groove 4 is provided on the positioning plate 2, and the positioning groove 4 is used to cooperate with the boss on the middle movable module 11 for positioning.

[0033] The stack mold support structure provided in this embodiment has a sliding foot 9 fixed to the bottom of the base plate 1 by a plurality of screws 6, and the base plate 1 and the support plate 7 are fixed by a plurality of countersunk screws 6. When in use, the support structure is placed on the slide rail 10 of the injection molding machine, and the sliding feet 9 on both sides of the bottom of the base plate 1 are respectively slidably set on the corresponding slide rails 10. The positioning plate 2 on the base plate 1 supports and connects to the bottom of the intermediate movable module 11 of the molding stack mold to support the bottom of the intermediate movable module 11. The boss at the bottom of the intermediate movable module 11 is stuck in the positioning groove 4 on the positioning plate 2, so that the intermediate movable module 11 is positioned with the positioning plate 2. The base plate 1 moves along the slide rail 10 to drive the intermediate movable module 11 to move. The base plate 1 and the positioning plate 2 thereon can effectively support the intermediate movable module 11, and can prevent the intermediate movable module 11 from falling during long-term movement. Moreover, through the sliding foot 9 and the slide rail 10 sliding in coordination, the positioning effect of the intermediate movable module 11 is good, and the equipment runs stably and reliably.

[0034] The slide foot 9 has a slide groove, which is mounted on the slide rail 10. Preferably, the slide rail 10 is in an inverted dovetail shape, an inverted L shape or a T shape, and the slide groove is adapted to the shape of the slide rail 10 so that the slide groove is stably mounted on the slide rail 10 to prevent the slide groove from falling off the slide rail 10.

[0035] In this embodiment, the stacking mold support structure also includes an oil injection pipe, which is used to introduce lubricating oil and lubricate the slide foot 9 and the slide rail 10. Specifically, the oil injection pipe can be externally connected to a lubricating oil supply device. In this embodiment, the oil injection pipe is connected to the lubrication system of the injection molding machine, and oil is supplied to the oil injection pipe in a regular and quantitative manner through the lubrication system, and then injected into the slide foot 9 and the slide rail 10 for lubrication. In this embodiment, the oil is automatically injected for three minutes every 2000 molds, so that the lubricating oil is fully lubricated by injecting oil to the slide foot 9 and the slide rail 10, ensuring that lubricating oil is supplied each time lubrication is performed, thereby ensuring that the slide rail 10 of the injection molding machine is not bitten or strained each time the mold is opened and closed, thereby increasing the service life of the equipment.

[0036] In this embodiment, the side wall of the bottom plate 1 is provided with an oil groove along the extending direction of the slide rail 10, and the oil filling pipe is connected with the oil groove. The lubricating oil of the oil filling pipe is first injected into the oil groove, and the excess lubricating oil in the oil groove emerges from the oil groove and flows downward to the slide foot 9 and the slide rail 10, thereby lubricating the slide foot 9 and the slide rail 10.

[0037] In order to accurately position the intermediate movable module 11 on the support structure, in this embodiment, the positioning grooves 4 are respectively provided on the two opposite sides of the positioning plate 2. Preferably, the positioning grooves 4 are located on the two opposite sides of the slide rail 10. When working, the intermediate movable module 11 and the stacking mold support structure move along the slide rail 10 at the same time. The bosses provided on the bottom side of the intermediate movable module 11 cooperate with the positioning grooves 4 to prevent the intermediate movable module 11 from moving in a direction perpendicular to the slide rail 10 and causing inaccurate positioning, thereby improving the positioning accuracy of the intermediate movable module 11.

[0038] In this embodiment, specifically, Figure 2 As shown, a support block 3 is provided between the base plate 1 and the positioning plate 2, and the positioning plate 2 is fixed on the support block 3. In order to make the positioning plate 2 have a sufficient height so that the positioning plate 2 can be supported on the bottom of the intermediate movable module 11, a support block 3 is provided between the positioning plate 2 and the base plate 1. Preferably, at least two support blocks 3 are provided in parallel along the extension direction of the slide rail 10. The width of the support block 3 is smaller than the width of the base plate 1 or the positioning plate 2, and a plurality of support blocks 3 are provided at intervals along the width direction of the base plate 1, which can greatly reduce the weight of the stacking mold support structure, so as to push the stacking mold support mechanism to move along the slide rail 10, and at the same time, it can save materials for manufacturing the support block 3, which helps to reduce costs. Specifically, the positioning plate 2 and the support block 3 are fixed by countersunk screws 6, which is convenient for disassembly and partial replacement when the positioning plate 2 is partially damaged, thereby reducing the use cost.

[0039] In order to further increase the height of the stack mold support structure, in this embodiment, a support plate 7 is provided between the bottom plate 1 and the support block 3, and the support block 3 is fixed on the support plate 7. By cooperating and stacking the support plate 7 and the support block 3, the stack mold support structure can have a suitable height, and at the same time, the weight of the stack mold support structure as a whole can be reduced.

[0040] In order to make the stack mold support structure have a sufficient height and to further reduce the weight of the stack mold support structure, in this embodiment, Figure 3 and Figure 4 As shown, a cushion block 8 is arranged between the bottom plate 1 and the support plate 7, at least two cushion blocks 8 are arranged in parallel along the extension direction of the slide rail 10, and the support plate 7 is fixed on the cushion blocks 8. The width of the cushion block 8 is smaller than the width of the bottom plate 1, and multiple cushion blocks 8 can be arranged according to actual needs. Under the premise of supporting the intermediate movable module, the weight of the entire stack mold support structure can be reduced, the material for manufacturing the support plate 7 can be saved, and the cost can be reduced.

[0041] More preferably, the length of the lower portion of the support block 3 is greater than the length of the upper portion. When the required height and length of the support are met, the upper portion of the support block 3 is less than the lower portion, forming a "convex"-shaped structure or a trapezoidal structure with a short upper portion and a long lower portion, which can save manufacturing materials, reduce weight, and reduce costs.

[0042] In this embodiment, a pad 5 is provided between the bottom plate 1 and the slide foot 9. Specifically, a groove is provided at the bottom of the bottom plate 1, the pad 5 is installed in the groove, and the top of the slide foot 9 is fixed to the pad 5 and the bottom plate 1 by screws 6. The pad 5 can protect the bottom plate 1 and make the fixation between the slide foot 9 and the bottom plate 1 more stable.

[0043] like Figure 5 As shown, this embodiment also provides a molding stack mold, including a first module and a second module, at least one intermediate movable module 11 is arranged between the first module and the second module, and the two sides of the intermediate movable module 11 are respectively formed in cooperation with the first module and the second module, and also includes the above-mentioned stack mold support structure, and the intermediate movable module is fixed on the stack mold support structure.

[0044] When in use, the first module is fixed on the movable platen of the injection molding machine, the second module is fixed on the fixed platen of the injection molding machine, the stacking mold support structure is placed on the slide rail 10 of the injection molding machine, and the horizontal balance is adjusted. There are two groups of oil injection pipes, which are respectively arranged on both sides of the bottom plate 1. The two groups of oil injection pipes are connected to the lubrication system of the injection molding machine, which are used to respectively supply lubricating oil to the corresponding slide feet 9 and slide rails 10 to ensure that the slide feet 9 and the injection molding machine slide rails 10 are fully lubricated. The middle movable module is placed on the support plate 7 of the stacking mold support structure, and the boss on the bottom side of the middle movable module is stuck in the positioning groove 4. The injection molding machine is molded, the injection molding mobile platen and the middle movable module 11 are moved to stick to the fixed platen, the injection molding machine brake is high pressure, the first module and the second module are locked, and the hydraulic clamp is tightened to supplement the pressure. The first module and the second module are respectively formed with the two sides of the middle movable module 11. After the molding is completed, the mold is opened and the stacking mold support structure follows the injection molding mobile platen to open the mold. During the operation of the molding stack mold, the stack mold support structure always supports the middle movable module 11, which can effectively prevent the middle movable module 11 from falling, and at the same time improve the operation stability of the middle movable module 11. The molding stack mold includes the above-mentioned stack mold support structure and also has the beneficial effects of the above-mentioned stack mold support structure.
