Description

Technical Field

[0001] The utility model relates to a mould, in particular to a cloth pressing mould. Background Art

[0002] The beverage filling valve is a mechanical device used to fill beverages into containers. In the beverage filling valve, the sealing film plays a very important role. It can ensure the sealing of the filling process, prevent contamination, and maintain the sanitary quality of the beverage. At present, most of the beverage filling valve sealing films on the market are composed of cloth and rubber materials. This combination gives the sealing film excellent wear resistance, high temperature resistance and chemical corrosion resistance. In the beverage filling valve, the sealing film can fit tightly on the filling valve to form an effective seal, thereby ensuring the hygiene and sealing of the beverage during the filling process. In addition, by adding a base cloth, the wear resistance of the sealing film can be further improved. Through the processing of the cloth sandwiching process, the cloth and the rubber material support each other, so that the sealing film can reduce friction and wear during use, thereby extending the service life of the sealing film.

[0003] When processing the sealing membrane for beverage filling valves, first prepare the required cloth and rubber materials and ensure good adhesion between them. Then, use scissors or laser cutting machines to process and cut the cloth into appropriate shapes and sizes according to the design requirements. Next, paste or apply the rubber material on the surface of the cloth to ensure that it is firmly pasted. Next, clamp the processed cloth and rubber materials together and put them into the cloth clamping machine, and pressurize and heat them to make them tightly combined. Finally, take out the material after the cloth is clamped, cool it to room temperature, and then use scissors or laser cutting machines to cut it into the required shape and size.

[0004] However, the existing cloth-inserted sealing membrane is usually not pre-pressed and molded, but directly put into the mold for production, followed by the vulcanization process. However, the products produced in this way are prone to uneven distribution of cloth and uneven thickness of the rubber layer. This not only affects the quality of the product, but also leads to a high rate of product defects. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of well-known functions and well-known components.

[0027] like Figures 1 to 5 As shown, the utility model provides a cloth pressing mold, including a lower mold 1, an upper mold 2 is arranged above the lower mold 1, a pressing groove 3 is arranged at the upper end of the lower mold 1, a core groove 4 is arranged in the upper mold 2, a core 5 is arranged in the core groove 4, an ejection device 6 is arranged at the lower end of the pressing groove 3, a lower ring blade 7 is arranged at the upper end of the pressing groove 3, and an upper ring blade 8 is arranged at the lower end of the upper mold 2. By setting the core 5 and the pressing groove 3, the cut base cloth can be pre-pressed and formed. Further, as Figure 1, the lower mold 1 can be set as a cylindrical structure, and the outer diameter of the upper mold 2 is equal to the outer diameter of the lower mold 1. By setting the lower mold 1 and the upper mold 2 as cylindrical structures with the same outer diameter, on the one hand, it is convenient for production and processing, and on the other hand, the same outer diameter allows the lower mold 1 and the upper mold 2 to be used as a mold set and arranged in an array, which increases the possibility of expanding the production scale. In addition, if Figure 3 The pressing groove 3 can be matched with the lower end of the core 5, and the core 5 is movably arranged in the core groove 4. The shape is conveniently controlled by the mutual cooperation between the pressing groove 3 and the core 5, and then the core 5 is movably arranged in the core groove 4. During processing, the cut base cloth is first pressed around by the core groove 4, and then the core 5 is pressed down to pre-press the base cloth.

[0028] However, the base fabric after extrusion molding is easily stuck in the groove of the pressing groove 3, and needs to be taken out manually with tweezers, which is troublesome, and the tweezers made of metal material are easy to scratch the surface of the mold. Figure 5 , the ejection device 6 may include an active cavity 9, the active cavity 9 is set as a cylindrical groove, a fixed block 91 is set in the active cavity 9, and the fixed block 91 is set as a columnar structure. A spring 10 is movably set in the active cavity 9, the outer diameter of the spring 10 is smaller than the inner diameter of the active cavity 9, the inner diameter of the spring 10 is larger than the outer diameter of the fixed block 91, and the spring 10 is set to a high temperature resistant material. The position of the spring 10 is limited by the set fixed block 91, and the spring 10 can be freely moved in the active cavity 9 by the set active cavity 9, and the spring 10 is set to a high temperature resistant material to prevent the elasticity of the spring 10 from being affected at high temperature. Furthermore, an ejection block 11 is set above the spring 10, and the height of the ejection block 11 is higher than the lowest point of the pressure groove 3 when it is not squeezed, and the top height of the ejection block 11 is lower than the highest point of the pressure groove 3 when it is not squeezed. By setting the ejection block 11, when the base cloth is pre-pressed, the ejection block 11 is squeezed and the spring 10 is compressed. After the pre-pressing is completed, the spring 10 is no longer squeezed, and the stored elastic potential energy is released to lift the ejection block 11. In order to limit the movement range of the ejection block 11, a limit block 111 can be set at the lower ends of both sides of the ejection block 11, and a limit groove 112 is set at the lower end of the ejection block 11 corresponding to the spring 10. By setting the limit block 111 in conjunction with the active cavity 9, the movement range of the ejection block 11 can be limited to prevent the spring 10 from quickly bouncing up and bouncing the ejection block 11 away, thereby causing damage to the mold. The set limit groove 112 can better cooperate with the fixed block 91 to limit the position of the spring 10. In addition, by setting the top height of the ejection block 11 to be lower than the highest point of the pressing groove 3 and higher than the lowest point of the pressing groove 3, on the one hand, it will not affect the placement of the base cloth, and on the other hand, it is also convenient to take out the pre-pressed base cloth after the ejection block 11 is bounced. In fact, when the cut base fabric is pre-pressed, the edge of the base fabric may be squeezed and pulled by the middle of the base fabric, causing the edge to deform. Figure 4The lower ring blade 7 can be set as a ring structure with a triangular cross section, the outer side of the upper ring blade 8 cooperates with the inner side of the lower ring blade 7, and the upper ring blade 8 is set as a ring structure with a triangular cross section. The lower ring blade 7 is set to cooperate with the upper ring blade 8 to further cut the edge of the base fabric.

[0029] like Figures 1 to 5 When the mold is in use, first use a screw to pass through the screw hole in the middle of the core 5, install the upper mold 2 and the core 5 together on the cloth pressing mold machine, then fix the lower mold 1 under the machine, and then close the cloth pressing mold for heating treatment. After the mold is heated, place the cut base cloth in the pressing groove 3 for pre-pressing and forming. Multiple base cloths can be pressed each time, and each time it takes 10-15 seconds. At this time, open the cloth pressing mold, and then use tweezers to take out the pre-pressed base cloth, and repeat this process.

[0030] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
