[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] Reference Figs. 1-3 An oven for processing softened surfaces of automotive dashboards includes a hot oven 1 located above a mold frame 7. The hot oven 1 moves up and down above the mold frame 7 via a lifting mechanism. An inner moving frame 12 is slidably connected to the inner wall of the hot oven 1. A sliding mechanism is installed on the top of the inner moving frame 12, extending through to the top of the hot oven 1 and connected to the lifting mechanism. A downwardly protruding cutting blade 14 is fixedly connected to the bottom of the inner moving frame 12. The end of the cutting blade 14 near the inner wall of the hot oven 1 is a vertical plane, and the vertical plane of the cutting blade 14 is flush with the inner wall of the mold frame 7 in the vertical direction. The lifting mechanism includes a square plate 8 welded to the outer wall of the mold frame 7. Two cylinders 6 are symmetrically fixedly installed on the top of the square plate 8. A fixing plate 5 is fixedly connected to the top of the two cylinders 6. An electric heating tube 13 is installed on the top of the inner wall of the inner moving frame 12.

[0026] First, the continuous plastic sheet is conveyed to the top of the mold frame 7. Then, the cylinder 6 is activated, and the cylinder 6 moves downward, causing the fixed plate 5 to move downward. The downward movement of the fixed plate 5 causes the sliding mechanism and the hot oven 1 to move downward synchronously until the bottom of the hot oven 1 contacts the top surface of the plastic sheet. At this time, the cylinder 6 stops running, and the electric heating tube 13 is activated. The electric heating tube 13 converts electrical energy into heat energy, which acts on the plastic sheet, softening it. Then, the vacuum forming mold located in the mold frame 7 is activated, and the vacuum forming mold extracts the air from the bottom of the plastic sheet, creating a negative pressure. Under the negative pressure, the softened plastic sheet is adsorbed and adheres to the surface of the vacuum forming mold. After forming, the cylinder 6 is controlled to move downward again. At this time, the hot oven 1 cannot move downward, but the sliding mechanism drives the inner moving frame 12 to move downward. The downward-moving cutting blade 14 cuts off the top of the formed part of the sheet, thus facilitating the separation of the formed part from the rigid plastic sheet, making it easier to remove the formed product and facilitate the subsequent conveying of the continuous sheet.

[0027] The sliding mechanism comprises a connecting column 4 fixedly connected to the center of the bottom end of the fixed plate 5, the bottom end of the connecting column 4 is formed with a hollow annular part, the top end of the hollow annular part is fixedly connected with an upper sliding plate 3, the inner wall of the upper sliding plate 3 is slidingly connected with an extension rod 11 fixedly connected to the top center of the heat oven 1, the bottom end of the upper sliding plate 3 is fixedly connected with downward extending guide columns 2 at the four corners, the guide columns 2 penetrate into the inner cavity of the heat oven 1 and are fixedly connected to the top end of the inner moving frame 12, and four guide holes for the upward and downward sliding of the guide columns 2 are formed in the heat oven 1.

[0028] When the cylinder 6 is operated downward for the second time, the downward moving cylinder 6 drives the connecting column 4 to move downward through the fixed plate 5, the downward moving connecting column 4 drives the upper sliding plate 3 to move downward, the upper sliding plate 3 drives the guide columns 2 at the four corners of the bottom to slide downward along the guide holes, thereby driving the inner moving frame 12 to move downward, and the inner moving frame 12 drives the cutting blade 14 to cut the plastic plate material of the formed part, thereby separating the formed part from the continuous plate material.

[0029] It should be noted that since the edge of the cut part is located in the interior of the heat oven 1, the cut part is essentially in a heated environment, and is therefore heated and softened at the same time, so that the cutting blade 14 can achieve a quick and effective cutting effect.

[0030] The inner wall of the connecting column 4 is formed with a sliding groove 9, the vertical section of the sliding groove 9 is in a "convex" shape structure which is turned by one hundred and eighty degrees, the top of the extension rod 11 is formed with a protruding part, the protruding part of the extension rod 11 is slidingly connected in the wide part of the sliding groove 9, and the extension rod 11 is slidingly connected in the narrow part of the sliding groove 9.

[0031] When the cylinder 6 is operated downward for the second time, at this time the extension rod 11 remains stationary under the support of the heat oven 1, and the connecting column 4 moves downward, at this time the extension rod 11 moves upward relative to the connecting column 4, and the sliding groove 9 in the "convex" shape structure can prevent the extension rod 11 from separating from the connecting column 4.

[0032] The spring 10 is fixedly connected between the top end of the protruding part of the extension rod 11 and the inner wall top end of the sliding groove 9, and the diameter of the protruding part of the extension rod 11 is greater than the diameter of the extension rod 11.

[0033] When the connecting column 4 and the extension rod 11 slide relative to each other, at this time the spring 10 is compressed, and when the cylinder 6 is operated upward, at this time the spring 10 in the compressed state can be reset upward.

[0034] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model.
