[0018] 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.

[0019] Please see Figures 1-8 The present invention provides the following technical solution: an oven-type lifting swing rotational molding machine, which is provided with a base 1 for support and a limiting column 2 installed on the inner surface of the base 1.

[0020] Example 1: As Figures 1-4 The technical solution shown is provided by this utility model as follows: A rotary molding machine for an oven with integrated lifting mechanism, comprising: a hydraulic cylinder 3 installed in the middle section of the inner surface of a base 1, with a movable seat 4 telescopically connected to the upper surface of the hydraulic cylinder 3, and positioning seats 5 and 6 respectively installed on the upper surface of the movable seat 4; a slider 7 installed on the outer surface of the movable seat 4, and a guide rail 8 nested on the inner surface of the slider 7, with the guide rail 8 installed on the side of a limiting post 2; the limiting post 2 is provided with a limiting locking mechanism; Figure 4 As shown, the base 1 forms a lifting structure with the moving seat 4 through the hydraulic cylinder 3, and the moving seat 4 forms an integrated structure with the positioning seat 1 5 and the positioning seat 2 6. The moving seat 4 forms a limiting sliding structure with the limiting post 2 through the slider 7 and the guide rail 8.

[0021] When feeding is required, the hydraulic cylinder 3 assembled on the control base 1 is extended and adjusted to lower the height of the moving seat 4. Simultaneously, the positioning seats 5 and 6 assembled on the moving seat 4 are moved downward, thereby driving the oven bottom shell 14 to move downward. When the moving seat 4 moves, the slider 7 installed on the moving seat 4, together with the limiting post 2 installed on the base 1 and the guide rail 8 assembled thereon, controls the moving seat 4 to move downward in a limited manner, thereby improving the stability of the oven bottom shell 14 as it moves downward.

[0022] Example 2: Figure 3 and Figure 4The technical solution shown, based on Embodiment 1, further discloses a locking mechanism for adjusting the height of the oven bottom shell 14 during lifting, preventing it from sagging during height adjustment, improving the stability of lifting and lowering, and solving the problems of inconvenient height adjustment and difficulty in locking and positioning. The specific details are as follows: The limiting locking mechanism includes a locking cylinder 9 disposed on the upper surface of the limiting post 2, and a rod 10 is telescopically connected to the inner surface of the locking cylinder 9. Both the outer surfaces of the locking cylinder 9 and the rod 10 are rotatably connected to connecting rods 11, which are rotated and positioned on the limiting post 2. Simultaneously, a locking element 12 is installed on the outer surface of the connecting rod 11, and the locking element 12 is fitted onto the outer surface of the movable seat 4. Figure 4 As shown, the limiting post 2 and the connecting rod 11 form a positioning and rotating structure, and the connecting rod 11 is symmetrically arranged about the middle section of the inner surface of the limiting post 2. The symmetrical connecting rods 11 are connected by a locking cylinder 9 and a rod 10 to form a telescopic structure. At the same time, the connecting rod 11 is connected by a locking member 12 to the moving seat 4 to form a locking structure.

[0023] Before the oven bottom shell 14 is lowered, the locking cylinder 9 and the air rod 10 are extended and retracted, and the connecting rod 11 is adjusted to extend and deflect on the limit post 2. The locking part 12 installed on the connecting rod 11 is disengaged from the pressing and locking of the edge of the moving seat 4, thereby controlling the oven bottom shell 14 to move downward. The required product is placed on the material rack 20, and the upper cover 18 assembled on the oven bottom shell 14 is closed. After the oven bottom shell 14 moves upward, the locking cylinder 9 and the air rod 10 can be opened, thereby pressing and locking the edge of the moving seat 4 by the locking part 12 assembled on the connecting rod 11, controlling the stability of the oven bottom shell 14 when it swings.

[0024] Example 3: Figures 5-8 The technical solution shown, based on Embodiment 2, further discloses the opening and closing of the upper cover 18 during the operation of the oven bottom shell 14, controlling the stability of automatic opening and closing, and controlling the stable placement and slight rotation of the product to promote complete material adhesion. This solves the problem that the upper cover 18 is inconvenient for automatic opening and closing for loading and unloading during the operation of the oven bottom shell 14. The specific details are as follows: Gear 13 is rotatably connected to the outer surface of the positioning seat 5, and the shaft of gear 13 is connected to the oven bottom shell 14. A mixing component 15 is nested on the side wall of the oven bottom shell 14, and the oven bottom shell 14 is equipped with a positioning and flipping mechanism; Figure 5 As shown, gear 13 and positioning seat 5 form a rotating structure, gear 13 and oven bottom shell 14 form a nested structure, and oven bottom shell 14 and mixing assembly 15 form an internal structure; as Figure 6 and Figure 7As shown, the positioning and flipping mechanism includes an opening and closing cylinder 16 rotatably connected to the outer surface of the oven bottom shell 14, and a second air rod 17 is telescopically connected to the inner surface of the opening and closing cylinder 16. A top cover 18 is rotatably connected to the outer end of the second air rod 17, positioning and rotating the top cover 18 at the top of the oven bottom shell 14. Simultaneously, a support base 19 is provided at the bottom of the oven bottom shell 14, and a material carrier 20 is rotatably connected to the inner surface of the oven bottom shell 14. A driver 21 is connected to the outer surface of the material carrier 20, and the driver 21 is positioned and mounted on the oven bottom shell 14. Figure 7 and Figure 8 As shown, the oven bottom shell 14 forms a telescopic and rotating structure with the top cover 18 through the opening and closing cylinder 16 and the second air rod 17, and the oven bottom shell 14 forms a supporting structure with the support base 19, and the oven bottom shell 14 forms a nested structure with the material rack 20, while the material rack 20 forms a rotating structure with the driver 21.

[0025] After the oven bottom shell 14 is lowered, it is supported by the support base 19 at the bottom. The support base 19 can also support the unused material carrier 20. The opening and closing cylinder 16 assembled in the oven bottom shell 14 can be controlled to extend and retract, and the control air rod 17 can be opened. The top cover 18 of the oven bottom shell 14 can be flipped open to place the product on the material carrier 20. After the top cover 18 is closed, the oven bottom shell 14 is adjusted to move up and lock. The drive device installed on the positioning seat 5 of the moving seat 4 is controlled to control the oven bottom shell 14 connected to the gear 13 to swing. In conjunction with the mixing component 15, the material is evenly spread during the swing, which is convenient for adhering to the product. The drive 21 assembled on the side of the oven bottom shell 14 is controlled to adjust the material carrier 20 to deflect at a small angle, thereby controlling the stability of the material adhering to the product and improving the lifting and swinging stability of the oven body used in the operation of the swing rotational molding machine.
