Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to a waste-free flat plate structure for a vulcanizing machine. Background Technology

[0002] In the daily production of rubber products, vulcanization is required to improve their physical properties. Raw rubber undergoes a chemical reaction with a vulcanizing agent (such as sulfur) under specific temperature, pressure, and time conditions, transforming it into a three-dimensional network structure. Currently, flatbed hot press molding machines are commonly used. However, these machines generate a significant amount of waste material from the sprues of the raw parts, requiring frequent worker intervention to remove burrs, resulting in high labor intensity and low production efficiency. Furthermore, the cost of vulcanized rubber compounds is relatively high, and the resulting waste necessitates secondary processing, further increasing production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a waste-free structure for a vulcanizing machine flat plate, so as to solve the problems mentioned in the background art.

[0004] To solve the above technical problems, this utility model provides the following technical solution: a waste-free structure for a vulcanizing machine plate, including a top seat, an upper heating plate fixed to the bottom wall of the top seat, a cooling plate fixed to the bottom wall of the upper heating plate, and the bottom wall of the cooling plate being used to install an upper mold; The top seat has two opposite side walls with lifting plates. A cylinder is fixed on the upper surface of the lifting plate. The telescopic end of the cylinder slides through the lifting plate and is fixedly connected to a guide plate. Two fixed guide plates are laterally adjustable with brackets on their opposite side walls. A mold and a middle heating plate are mounted on the brackets. A material trough is provided on the mold. Uncured rubber material is placed in the material trough. Multiple small discharge holes are opened on the bottom wall of the material trough. An upper mold is also installed on the bottom wall of the middle heating plate. It also includes a lower mold, which is located below the bracket and is directly opposite the upper mold on the bottom wall of the cooling plate. A base is provided below the lower mold, and the bottom wall of the base is used to connect to an external cylinder. The bracket is adjusted laterally to move the mold and the middle heating plate alternately to directly below the cooling plate.

[0005] In a further embodiment, when the mold moves to directly below the cooling plate, the telescopic end of cylinder one retracts, causing the mold to rise and close with the upper mold on the bottom wall of the cooling plate, which can squeeze the unvulcanized rubber material out of the discharge hole. The lower mold is used to receive the unvulcanized rubber material squeezed out from the discharge hole, and the unvulcanized sprue is retained in the material tank for recycling.

[0006] In a further embodiment, when the middle heating plate moves directly below the cooling plate, the telescopic end of the external cylinder on the bottom wall of the base is stretched, causing the lower mold to rise and close with the upper mold on the bottom wall of the middle heating plate, thus enabling the vulcanized rubber material to be molded. The middle heating plate provides constant temperature for mold closing.

[0007] In a further embodiment, the two fixed guide plates are provided with grooves on their opposite sidewalls, and the bracket is provided with sliding strips on its two long sidewalls that are respectively slidably engaged with the two grooves.

[0008] In a further embodiment, an mounting plate is fixedly installed between the same end of the two fixed guide plates, and a second cylinder is fixedly installed on the outer wall of the mounting plate.

[0010] In a further embodiment, the outer wall of the guide rod is slidably fitted with a plurality of collars, and the rubber collars are located between the anti-detachment enlarged end and the hollow guide post.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model is a waste-free structure for a vulcanizing machine flat plate. When the mold moves directly below the cooling plate, the unvulcanized rubber material is first squeezed out from the discharge hole into the lower mold. The unvulcanized sprue is retained in the material trough for recycling and reuse, effectively reducing the generation of waste.

[0014] 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.

[0015] This embodiment provides a waste-free structure for a vulcanizing machine flat plate, such as... Figure 1 As shown, it includes a top seat 9, which is fixedly installed on the pre-installation position of the vulcanizing machine frame to ensure that its installation position is accurate and firm.

[0016] An upper heating plate 8 is fixed to the bottom wall of the top seat 9, and a cooling plate 5 is fixed to the bottom wall of the upper heating plate 8. The bottom wall of the cooling plate 5 is used to mount the upper mold. The upper heating plate 8 is used for heating, and the cooling plate 5 is used for cooling.

[0017] The top seat 9 has two opposite side walls equipped with lifting plates 3. A cylinder 10 is fixed to the upper surface of the lifting plate 3. The telescopic end of the cylinder 10 slides through the lifting plate 3 and is fixedly connected to a fixed guide plate 1. The telescopic end of the cylinder 10 can extend or retract, which can drive the fixed guide plate 1 to rise or fall.

[0018] Two fixed guide plates 1 are laterally adjustable with brackets 7 on their opposite side walls. A mold 6 and a middle heating plate 4 are installed on the brackets 7. A material trough is provided on the mold 6, which is used to place uncured rubber material. Multiple small discharge holes are opened on the bottom wall of the material trough. An upper mold is also installed on the bottom wall of the middle heating plate 4. When the fixed guide plates 1 are raised and lowered, they can drive the mold 6 and the middle heating plate 4 on the brackets 7 to raise and lower synchronously.

[0019] It also includes a lower mold 16, which is located below the bracket 7 and is directly opposite the upper mold on the bottom wall of the cooling plate 5. A base 17 is provided below the lower mold 16, and the bottom wall of the base 17 is used to connect to an external cylinder, which provides power for the lower mold 16 to rise and fall. This ensures that the lower mold 16 can accurately connect with the upper mold on the bottom wall of the cooling plate 5 when the mold is closed after it is raised.

[0020] The bracket 7 can be adjusted laterally, such as... Figure 2 As shown, each of the two fixed guide plates 1 has a groove 15 on its opposite sidewall. The two long sidewalls of the bracket 7 are each provided with a sliding strip 14 that slides and engages with the two grooves 15. A mounting plate is fixedly installed between the two fixed guide plates 1 at the same end. A cylinder 13 is fixedly installed on the outer wall of the mounting plate. The telescopic end of the cylinder 13 slides through the mounting plate and is fixedly connected to the end sidewall of the bracket 7. The telescopic end of the cylinder 13 alternates between stretching and contracting, which can drive the mold 6 and the middle heating plate 4 to alternately move directly below the cooling plate 5.

[0021] Traditional flatbed hot press molding machines generate a large amount of waste sprue marks during production, which not only wastes raw materials but also increases production costs due to the need for secondary processing of the waste. Therefore, when the mold 6 moves directly below the cooling plate 5, the telescopic end of cylinder 10 retracts, causing the mold 6 to rise and close with the upper mold on the bottom wall of the cooling plate 5. This allows the unvulcanized rubber to be extruded from the discharge hole. The lower mold 16 receives the unvulcanized rubber extruded from the discharge hole, and the unvulcanized sprue marks remain in the material trough for recycling. In this structure, the unvulcanized sprue marks remaining in the material trough can be recycled, greatly reducing waste generation and lowering the cost of rubber usage and secondary processing.

[0022] Then, the cylinder 13 retracts, and the sliding bar 14 of the bracket 7 slides in the opposite direction along the groove 15, moving the middle heating plate 4 directly below the cooling plate 5. The telescopic end of the external cylinder on the bottom wall of the base 17 is stretched, causing the lower mold 16 to rise and close with the upper mold on the bottom wall of the middle heating plate 4, thus enabling the vulcanized rubber material to be molded.

[0023] Specifically, initial preparation: Before starting the equipment, check that all components are securely installed and that the cylinders, heating plates, and other equipment are functioning properly. Place the uncured rubber compound into the material trough of mold 6, ensuring that the rubber compound is evenly distributed.

[0024] Mold 6 Closure and Extrusion: Activate cylinder 13 to extend its telescopic end, causing the bracket 7 to move laterally, bringing mold 6 directly below cooling plate 5. Then activate cylinder 10 to retract its telescopic end, causing mold 6 to rise and close with the upper mold on the bottom wall of cooling plate 5. During mold closure, unvulcanized rubber is extruded from the discharge hole under pressure. Lower mold 16 receives the extruded unvulcanized rubber, while the unvulcanized sprue remains in the trough for recycling.

[0025] Mold Closure and Vulcanization of the Middle Heating Plate 4: After mold closure and extrusion are completed, cylinder 13 is activated again to move the bracket 7 laterally, causing the middle heating plate 4 to move directly below the cooling plate 5. At this time, the external cylinder is activated to extend its telescopic end, causing the lower mold 16 to rise and close with the upper mold on the bottom wall of the middle heating plate 4. Simultaneously, during this process, the middle heating plate 4 provides constant temperature for mold closure. The heating temperature of the middle heating plate 4 is set according to the required temperature of different rubber compounds, ensuring stable temperature conditions for the rubber compound during vulcanization. This facilitates full vulcanization of the rubber compound, thereby guaranteeing the quality and performance stability of the rubber products and reducing the product defect rate caused by temperature fluctuations.

[0026] Demolding and cyclic production: After vulcanization, the telescopic ends of cylinder 10 and the external cylinder extend and retract respectively, separating mold 6 and lower mold 16, thus completing demolding. The above steps are then repeated cyclically to achieve continuous production. During production, the cylinder motion parameters, heating plate temperature parameters, and the amount of rubber material can be adjusted according to actual production needs to ensure production efficiency and product quality.

[0027] Meanwhile, traditional equipment requires frequent worker intervention for operations such as waste removal, leading to production interruptions and low efficiency. This structure uses a cylinder-driven bracket to alternately move the mold and the middle heating plate to directly below the cooling plate for mold closing, achieving continuous production, reducing manual intervention and downtime, and significantly improving production efficiency.

[0028] In this embodiment, further, such as Figure 1 As shown, hollow guide columns 12 are provided at the four corners of the top seat 9. Guide rods 2 are axially inserted into the hollow guide columns 12. The top wall of the guide rods 2 is provided with an anti-detachment enlarged end to prevent the guide rods 2 from coming out of the hollow guide columns 12. The bottom walls of the two guide rods 2 on the same side wall are fixedly connected to the upper end face of the fixed guide plate 1 to ensure the movement stability of the fixed guide plate 1.

[0029] Meanwhile, multiple collars 11 are slidably sleeved on the outer wall of the guide rod 2, with the rubber collars 11 located between the anti-detachment enlarged end and the hollow guide post 12. The purpose of adding collars 11 to the outer wall of the guide rod 2 is to adjust the vertical height between the upper mold of the bottom wall of the cooling plate 5 and the middle heating plate 4 according to the size of the mold, thereby shortening or lengthening the extension stroke of the cylinder 10.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
