Technical Field

[0001] This utility model relates to the field of PVA mop head technology, specifically a PVA mop head forming mold. Background Technology

[0002] A PVA mop is a cleaning tool with a polyvinyl alcohol (PVA) sponge as the mop head material. It is mainly used for cleaning smooth surfaces such as floors, windows, and kitchen walls in the home. The material has strong water absorption and can quickly absorb water, oil, hair and other stains. It supports both wet and dry use and comes with a replaceable sponge head.

[0003] The molding mold for the PVA mop head is a plastic mold. After pouring the mixture into the mold, it is placed in a steamer and steamed to form the head. However, the mold has a certain depth, and after pouring the mixture into the mold, air bubbles are easily generated inside and cannot be discharged, which affects the quality of the PVA mop head after molding. Therefore, we propose a molding mold for PVA mop heads to solve this defect of the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a molding die for forming a plywood mop head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for forming a cotton mop head, comprising a mold base, a plurality of feeding holes evenly distributed on the mold base, and a plurality of mold forming cylinders respectively connected to the feeding holes at the lower end of the mold base. The lower end of the mold base is provided with a plurality of straight tubes evenly distributed in annular rings outside the mold forming cylinders. A plurality of sealing outer cylinders are evenly connected to the side of the straight tubes facing the mold forming cylinders. An elastic element is provided inside the sealing outer cylinder. The other end of the elastic element is provided with a movable sealing rod that slides and penetrates inside the sealing outer cylinder. The other end of the movable sealing rod is provided with a striking ball.

[0006] A connecting component is provided between the lower ends of the straight pipes to connect them to each other. A pressurizing gas supply component is provided on the connecting component. The pressurizing gas supply component discharges gas into the sealed outer cylinder and pushes the movable sealing rod to move, so that the striking ball strikes the outside of the mold forming cylinder.

[0007] Using the above technical solution, the gas is supplied through the connecting component to the sealed outer cylinder connected to the straight pipe by the pressurized gas supply component. Under the action of air pressure, the moving sealing rod moves and seals inside the sealed outer cylinder. The elastic element extends synchronously, driving the striking ball to move synchronously, and uniformly striking the surface of the mold forming cylinder. This achieves the removal of air bubbles in the mixture poured into the mold forming cylinder. Through the repeated inflation and deflation of the pressurized gas supply component, as well as the extension and contraction of the elastic element, the striking ball repeatedly strikes the outside of the mold forming cylinder.

[0008] As a preferred embodiment of this utility model, the elastic element is a stainless steel spring, but is not limited to stainless steel springs.

[0009] In a preferred embodiment of this invention, when the elastic element is in an extended state, the striking ball contacts the outside of the mold forming cylinder; when the elastic element is in a contracted state, the striking ball separates from the outside of the mold forming cylinder.

[0010] By adopting the above technical solution, it is ensured that the striking ball has a moving striking stroke.

[0011] As a preferred embodiment of this invention, the striking ball is a rubber ball, but is not limited to rubber balls.

[0012] As a preferred technical solution of this utility model, the connecting component includes an annular tube connecting the lower ends of the straight tubes outside each mold forming cylinder, a connecting tube connecting the lower ends of the longitudinal annular tubes, and a rigid hollow tube connecting the connecting tubes.

[0013] By adopting the above technical solution, the interconnection between the connecting pipe, the ring pipe, the rigid hollow pipe and the straight pipe is achieved, thus realizing the interconnection between the various straight pipes.

[0014] In a preferred embodiment of this invention, the pressurized air supply assembly includes a pressurized air pump, with an air pipe connecting the air inlet of the pressurized air pump to the rigid hollow tube, and an automatic exhaust valve connected to the outside of the air pipe.

[0015] Using the above technical solution, the booster pump operates, and by utilizing the interconnection between the booster pump, air pipe, connecting pipe, rigid hollow pipe, automatic exhaust valve, annular pipe, straight pipe and sealing outer cylinder, gas is filled into the sealing outer cylinder, and the automatic exhaust valve opens to discharge the gas inside the sealing outer cylinder.

[0016] As a preferred embodiment of this utility model, the air tube and the connecting tube are detachably connected.

[0017] The above technical solution facilitates the disconnection of the air pipe from the connecting pipe, thereby enabling the separation of the overall pressurized air supply assembly.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] This PVA mop head forming mold uses a pressurized air supply component to discharge gas through a connecting component into a sealed outer cylinder connected to a straight pipe. Under the action of air pressure, the moving sealing rod moves within the sealed outer cylinder, and the elastic element extends synchronously, driving the striking ball to move and evenly strike the surface of the forming cylinder. Through the repeated inflation and deflation of the pressurized air supply component, as well as the extension and contraction of the elastic element, the striking ball repeatedly strikes the outside of the forming cylinder. Compared with existing technologies, this method removes air bubbles from the mixture injected into the forming cylinder through striking, ensuring the quality of the formed PVA mop head.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 6 The molding die for a PVC mop head in this embodiment mainly comprises a mold base 1, a feeding hole 2, a molding cylinder 3, a straight tube 4, a sealing outer cylinder 5, an elastic element 6, a movable sealing rod 7, a striking ball 8, a connecting component, and a pressurized air supply component.

[0029] The mold base 1 is made of plastic material. Multiple feeding holes 2 are evenly distributed on the mold base 1. The feeding holes 2 are processed with high precision to ensure dimensional accuracy and surface roughness. Multiple mold forming cylinders 3 are fixed on the lower surface of the mold base 1. The mold forming cylinders 3 are made of high-strength plastic material and have good high temperature resistance and corrosion resistance. Each mold forming cylinder 3 is connected to the feeding hole 2.

[0030] Multiple straight tubes 4 are fixed to the lower end of the mold base 1. The straight tubes 4 are made of plastic and are divided into multiple groups. Each group consists of several annularly distributed tubes on the outside of the mold forming cylinder 3. Multiple vertically distributed sealing outer cylinders 5 are connected at equal intervals on the side facing the mold forming cylinder 3. The sealing outer cylinder 5 is made of high-strength plastic and has an elastic element 6 fixed inside. The elastic element 6 is made of stainless steel spring, which has good elasticity and corrosion resistance. It is not limited to stainless steel springs and can be other alternative elastic telescopic structures. The other end of the elastic element 6 is fixed with a movable sealing rod 7. The movable sealing rod 7 slides and seals inside the sealing outer cylinder 5 and passes through to the outside of the sealing outer cylinder 5. The movable sealing rod 7 is made of high-strength plastic with a smooth surface to reduce friction. The other end of the movable sealing rod 7 is fixed with a striking ball 8. The striking ball 8 is a rubber ball with good elasticity and wear resistance. It is not limited to rubber balls and the material can be selected and replaced according to the actual use.

[0031] It should be added that: when the elastic element 6 is in the extended state, the striking ball 8 is in contact with the outside of the mold forming cylinder 3; when the elastic element 6 is in the contracted state, the striking ball 8 is separated from the outside of the mold forming cylinder 3.

[0032] A connecting assembly is provided between the lower ends of the straight pipes 4 to connect the straight pipes 4 to each other. The connecting assembly includes an annular pipe 9, a connecting pipe 10, and a rigid hollow pipe 11. The annular pipe 9 is made of plastic and connects the lower ends of the straight pipes 4 on the outside of each mold forming cylinder 3. The lower ends of the annular pipes 9 are connected by the connecting pipe 10, which is made of high-strength plastic. The connecting pipes 10 are connected by the rigid hollow pipe 11, which is also made of high-strength plastic, to ensure stable gas delivery.

[0033] The connecting component is equipped with a pressurized air supply component, which discharges gas into the sealed outer cylinder 5 and pushes the movable sealing rod 7 to move, so that the striking ball 8 strikes the outside of the mold forming cylinder 3. The pressurized air supply component includes a pressurized air pump 12, an air pipe 13, and an automatic exhaust valve 14. The pressurized air pump 12 is a high-efficiency piston air pump with good inflation efficiency and stability. The air pipe 13 is connected between the air inlet of the pressurized air pump 12 and the rigid hollow tube 11. The air pipe 13 is made of high-pressure resistant rubber material to ensure the reliability of gas delivery. The outside of the air pipe 13 is connected to the automatic exhaust valve 14. The automatic exhaust valve 14 is a high-precision solenoid valve to ensure the timeliness and accuracy of exhaust. The air pipe 13 is detachably connected to the connecting pipe 10. After the mixture is filled, the pressurized air supply component is detached.

[0034] The preparation of the mold involves pouring the mixture into the mold forming cylinder 3 through the feeding hole 2, and the mixture is initially formed in the mold forming cylinder 3.

[0035] During the pressurization and striking process, the pressurization pump 12 operates, discharging gas through the air pipe 13 and the rigid hollow pipe 11 into the annular pipe 9 and the connecting pipe 10, and finally into the straight pipe 4 and the sealing outer cylinder 5. Under the action of air pressure, the moving sealing rod 7 slides and seals inside the sealing outer cylinder 5, and the elastic element 6 extends synchronously, driving the striking ball 8 to move towards the outside of the mold forming cylinder 3 and strike it.

[0036] Exhaust and reset: When it is necessary to stop the tapping, the automatic exhaust valve 14 opens, the gas in the sealed outer cylinder 5 is discharged, the elastic element 6 contracts under its own elastic force, and drives the tapping ball 8 to separate from the outside of the mold forming cylinder 3, completing one tapping cycle. Through the repeated filling and exhaust of the pressurized air supply component, the tapping ball 8 repeatedly taps the outside of the mold forming cylinder 3, and the air bubbles in the mixture inside the mold forming cylinder 3 are discharged.

[0037] Technical advantages and efficient air exhaust: Through the synergistic effect of the pressurized air supply component and the striking ball 8, air bubbles in the mixture inside the mold forming cylinder 3 are effectively expelled, improving the quality of the molded cotton mop head.

[0038] Evenly distributed impact: The impact balls 8 are evenly distributed on the outside of the mold forming cylinder 3 to ensure that the mold forming cylinder 3 is fully impacted and to avoid local air bubbles.

[0039] Automatic control: The combination of the booster air supply component and the automatic exhaust valve 14 enables the automated knocking and exhaust process, thereby improving production efficiency.

[0040] Intelligent control system, controller: adopts PLC programmable logic controller or single-chip microcomputer as the core controller, with high reliability and powerful control functions.

[0041] In summary, the plywood mop head forming mold effectively removes air bubbles from the mixture inside the forming cylinder 3 through the synergistic effect of the pressurized air supply component and the striking ball 8, significantly improving the quality of the formed plywood mop head. This equipment has broad application prospects in the field of plywood mop head forming.
