Description
TECHNICAL FIELD
[0001] The utility model relates to shoe material processing technical field especially a sole mould with exhaust hole adjusting mechanism. BACKGROUND
[0002] In some shoe sole material injection processing needs to set up exhaust hole, to facilitate the air discharge between shoe material and mould gap, thereby further improving the forming precision. For example, a kind of sole forming mould with exhaust function is disclosed in Chinese patent, patent No.202220596150.3, wherein it is recorded: including forming module, cavity structure and exhaust pipeline, the forming module is equipped with accommodating cavity, the cavity structure is located in the accommodating cavity, the inner wall of the accommodating cavity and the cavity structure are left with interval, the exhaust hole is opened in the forming module, the exhaust pipeline is located in the interval, and is connected with the exhaust hole, the cavity structure is made of breathable steel material, the utility model has the advantages of simple structure, reasonable design, when using, it can be installed in injection mould base and used, in the injection process, the cavity structure made of breathable steel has breathability, through the external assembly, the air in the cavity structure is extracted through exhaust hole and exhaust pipeline, to better complete sole forming.
[0003] The deficiency of prior art is that: exhaust hole and exhaust pipeline are directly opened on forming module, it is easy to understand that shoe material glue under high pressure will flow along exhaust hole or exhaust pipeline, and will solidify in exhaust hole or exhaust pipeline after cooling, seriously affecting the next use of mould. SUMMARY
[0004] In view of the deficiency of prior art, the utility model provides a kind of sole mould with exhaust hole adjusting mechanism.
[0005] The technical scheme of the utility model is:
[0006] A kind of sole mould with exhaust hole adjusting mechanism, including lower mould, upper mould and gas outlet groove, the lower mould and upper mould form cavity jointly, the upper mould is provided with injection mechanism corresponding cavity, the upper mould side is formed with multiple gas outlet grooves, the gas outlet groove is provided with movable plate by guide column, the upper mould is provided with screw rod, the lower end of the screw rod is rotatably connected movable plate upper part, the lower mould is provided with fixed plate corresponding movable plate, and exhaust passage is formed between the movable plate and fixed plate.
[0007] In one preferred embodiment of the present disclosure, the top of the screw rod is provided with a hand wheel, which facilitates the rotation of the screw rod, thereby playing the role of adjusting the height of the movable plate.
[0008] In one preferred embodiment of the present disclosure, the exhaust passage formed by the movable plate and the fixed plate is V-shaped.
[0009] In a preferred embodiment of the present disclosure, the exhaust channel formed by the movable plate and the fixed plate is W-shaped.
[0010] In a preferred embodiment of the present disclosure, the movable plate and the fixed plate are made of aluminum alloy, which is easy to clean and wear-resistant.
[0011] Beneficial effects of the utility model
[0012] According to the present disclosure, a plurality of exhaust channels for exhaust are constructed by using a movable plate following the upper mold and a fixed plate following the lower mold to discharge excess air during injection molding. After the injection molding is completed, the exhaust channels are opened by separating the upper and lower molds. At this time, the exhaust channels can be cleaned with tools such as scrapers to facilitate the next round of operations. In addition, the aperture of the exhaust channels can be adjusted by adjusting the movable plate. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural diagram of the present utility model.
[0014] In the figure, 1. lower mold; 2. cavity; 3. fixed plate; 4. upper mold; 5. injection mechanism; 6. air outlet groove; 7. guide column; 8. movable plate; 9. screw; 10. handwheel. DETAILED DESCRIPTION
[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:
[0016] Example 1
[0017] like Figure 1 As shown, a sole mold with a vent hole adjustment mechanism includes a lower mold 1, an upper mold 4, and an air outlet groove 6. The lower mold 1 and the upper mold 4 together form a cavity 2. The upper mold 4 is provided with an injection mechanism 5 corresponding to the cavity 2. A plurality of air outlet grooves 6 are formed on the side of the upper mold 4. A movable plate 8 is provided in the air outlet groove 6 through a guide column 7. The upper mold 4 is provided with a screw 9. The lower end of the screw 9 is rotatably connected to the upper part of the movable plate 8. The lower mold 1 is provided with a fixed plate 8 corresponding to the movable plate 8. An exhaust channel is formed between the movable plate 8 and the fixed plate 3. A handwheel 10 is provided on the top of the screw 9. The exhaust channel formed by the movable plate 8 and the fixed plate 3 is V-shaped.
[0018] In this embodiment, the mold cavity formed by the upper and lower molds is any conventional mold suitable for injection molding, and the injection mechanism is any conventional glue injection mechanism used for shoe sole injection molding. Furthermore, it is obvious that this utility model cannot be used independently and must be used in conjunction with conventional shoe material injection molding machines, glue supply equipment, etc. to complete the shoe sole injection molding process. The aforementioned methods are all conventional means in the art and will not be elaborated on in detail.
[0019] Embodiment 2
[0020] The difference between this embodiment and Embodiment 1 is that the exhaust passage formed by the movable plate and the fixed plate is in a W shape. The movable plate and the fixed plate are made of aluminum alloy.
[0021] The more winding exhaust passage can reduce the probability of the adhesive solution separating from the mold (i.e., prevent overflow), but the wear during cleaning will inevitably increase, so aluminum alloy is used to improve the wear resistance.
[0022] Although the mold according to the embodiments of the present disclosure has been described above, aspects of the present disclosure are not limited to the above-described embodiments, and the present disclosure can be implemented in various ways within the scope of the spirit of the present disclosure.
