Description

Technical Field

[0001] This invention belongs to the technical field of thermoforming equipment, and particularly relates to a thermoforming equipment with a side push rod. Background Technology

[0002] The working principle of thermoforming equipment is to perform heat processing on parts in a mold within a closed furnace. The specific operation process is as follows: First, open the front and rear furnace doors, fix the mold and parts to be processed on the heating platform, and close the furnace doors; then, heat the inside of the thermoforming furnace until the predetermined temperature is reached, and perform heat processing on the parts; finally, open the front and rear furnace doors, remove the parts, and the processing is completed.

[0003] During the processing, it may be necessary to move or turn the parts and molds. Conventional thermoforming equipment cannot meet this process requirement. Often, the equipment needs to be stopped after processing in one direction, and after cooling, the parts and molds need to be removed, the direction or movement reversed, and the equipment restarted for processing, resulting in a significant waste of time and resources. Summary of the Invention

[0004] The technical problem solved by the present invention is to overcome the shortcomings of the prior art and provide a thermoforming device with a side ejector pin, which aims to solve the problem of applying horizontal force to heated parts and molds during the processing due to process requirements.

[0005] To address the aforementioned technical problems, this invention discloses a thermoforming device with side push rods, comprising: a main frame, a hydraulic system, an upper heating platform, a furnace door assembly, a side push rod assembly, a lower heating platform, and a hydraulic slider; wherein, the hydraulic system is installed on the upper end of the main frame, and the hydraulic master cylinder of the hydraulic system extends through a through hole at the upper end of the main frame to the middle of the main frame and connects to the hydraulic slider; the upper heating platform is screwed to the hydraulic slider; the lower heating platform is screwed to the lower end of the main frame; the furnace door assembly is screwed to the four columns of the main frame; and the side push rod assembly is installed on the furnace door assembly.

[0006] In the aforementioned thermoforming equipment with side push rods, the hydraulic system operates by driving the hydraulic slide block up and down through the hydraulic master cylinder, which in turn drives the upper heating platform to move up and down, cooperating with the lower heating platform to achieve thermoforming of the parts.

[0007] In the aforementioned thermoforming equipment with side top rods, the furnace door assembly includes: a furnace door frame, an insulated outer cover plate, and a high-temperature resistant metal inner cover plate; wherein, the space between the insulated outer cover plate and the high-temperature resistant metal inner cover plate is filled with insulation material to form the furnace door; the furnace door is screwed onto the furnace door frame; after the furnace door frame is connected to the opening and closing cylinder, it is then bolted to the four columns of the main frame, closely attached to the upper heating platform and the lower heating platform, to achieve the insulation function.

[0008] In the aforementioned thermoforming equipment with side push rods, the side push rod assembly includes: a side push rod hydraulic cylinder, a cylinder mounting block, a side push rod, and a push rod mounting structure. The side push rod hydraulic cylinder is mounted on the cylinder mounting block via bolts and a flange, providing driving force for the extension and retraction of the side push rod. One end of the side push rod has a groove, which is directly connected to the side push rod hydraulic cylinder through a threaded hole in the center of the groove. The cylinder mounting block is mounted on the push rod mounting structure via a flange. The push rod mounting structure is bolted to the furnace door frame to install the entire side push rod assembly onto the furnace door assembly.

[0009] In the aforementioned thermoforming equipment with side push rods, there are reserved holes on both sides of the furnace door. The side push rods are installed by passing through the reserved holes to realize the push-in function.

[0010] In the aforementioned thermoforming equipment with side ejector pins, a guide structure is provided at the other end of the side ejector pin to guide the side ejector pin through the pre-drilled hole during the extension and retraction process, ensuring that the side ejector pin does not interfere with or collide with the pre-drilled hole during the heating process.

[0011] In the aforementioned thermoforming equipment with side push rods, heat insulation and sealing treatment are applied between the guide structure and the reserved hole to ensure that heat will not dissipate through the reserved hole and affect the heating efficiency.

[0012] In the aforementioned thermoforming equipment with a side ejector pin, a limiting structure is provided at the other end of the side ejector pin to limit the extension length of the side ejector pin.

[0013] The present invention has the following advantages: This invention discloses a thermoforming equipment with a side ejector rod. Based on the commonly used thermoforming equipment with upper and lower ejector rod structures, a side ejector rod is designed, which enables the thermoforming equipment to meet more process requirements. During the heating and forming process, the processed parts and molds can be moved and positioned not only in the vertical direction but also in the horizontal direction, ensuring the functionality of the thermoforming equipment and greatly improving the process versatility of the thermoforming equipment without stopping the heating operation.
