Description

Technical Field

[0001] This utility model specifically relates to the technical field of mold devices, and more specifically to a swing-type production mold device. Background Technology

[0002] Molds are tools used in industrial production to shape articles. Through specific structural shapes, raw materials (such as metals, plastics, rubber, etc.) are formed into products with certain shapes and sizes under pressure, temperature, or other external forces. Rotational molding molds are one type of mold used in rotational molding processes. By adding powdered or paste-like plastic materials into the mold, and through processes such as heating, rolling, and cooling, the material is evenly distributed in the inner cavity of the mold and melted. Finally, it is cooled and demolded to obtain hollow plastic products. Rotational molding molds require the use of mold devices.

[0003] Existing rotational molding equipment typically uses a combination of oscillation and rotation to distribute the material evenly inside the mold. During processing, the inside of the mold is usually sealed, and an external heating source is usually required to continuously heat the mold. However, existing rotational molding molds are completely exposed to an open environment during heating, resulting in significant heat loss. Furthermore, manual assistance is usually required to remove the product from the mold during demolding, leading to low production efficiency. Therefore, these equipment have drawbacks in use. Utility Model Content

[0004] The purpose of this invention is to provide a swing-type production mold device to solve the problems mentioned in the background art, such as the existing rotational molding mold being completely exposed to an open environment during heating, resulting in large heat loss, and the need for manual assistance to remove the product from the mold during demolding, leading to low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A swing-type production mold device includes a main frame and a rotational molding mold.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 In this embodiment of the present invention, a swing-type production mold device includes a main frame 1 and a rotational molding mold 12. A secondary frame 2 is installed at the rear of the main frame 1, and a second motor 16 is installed at the top of the secondary frame 2. The output shaft of the second motor 16 is connected to a movable plate 17, and a connecting rod 18 is installed at the other end of the movable plate 17. The end of the connecting rod 18 is rotatably connected to the bottom of one side of the movable frame 3. Two rotating shafts 5 are symmetrically distributed at both ends of the movable frame 3, and a hanger 4 is installed at the bottom of the movable frame 3. Meanwhile, the two rotating shafts 5 are rotatably connected to the top ends of the main frame 1 respectively; the top of the movable frame 3 is symmetrically equipped with two bearing seats 19; the upper front end of the movable frame 3 is equipped with an upper heat insulation cover 9, and the lower front end of the movable frame 3 is equipped with a lower heat insulation cover 10; one end of the rotational molding mold 12 is connected to one end of the main shaft 11, and the main shaft 11 is rotatably connected to both bearing seats 19, while the end of the main shaft 11 is connected to a pneumatic slip ring 13; the pneumatic slip ring 13 is fixed to the top rear end of the movable frame 3.

[0025] More specifically, the pneumatic slip ring 13 is fixed to the top of the movable frame 3 by bolts.

[0026] As a further explanation of this embodiment, the hanger 4 moves synchronously with the movable frame 3.

[0027] In this embodiment, the movable frame 3, connecting rod 18, movable plate 17 and rotational molding mold 12 form a rotating structure, and the axis of rotational molding mold 12 is on the same straight line as the axis of main shaft 11.

[0028] More specifically, the connection between the second motor 16 and the drive movable plate 17 is equipped with a speed reduction mechanism.

[0029] As a further explanation of this embodiment, when the second motor 16 is started, the movable plate 17 is driven to rotate slowly. At the same time, the connecting rod 18 drives the movable frame 3 to swing up and down continuously, thereby driving the rotational molding mold 12 to swing up and down synchronously. The rotational molding mold 12 allows the raw material to be evenly distributed on the inner wall of the rotational molding mold 12.

[0030] In this embodiment, a first motor 15 is installed on one side of the top of the hanger 4, and the output shaft of the first motor 15 is connected to the main shaft 11 by chain drive. At the same time, the main shaft 11 and the rotational molding mold 12 form a rotating structure.

[0031] To be more specific, the first motor 15 is started to drive the main shaft 11 to rotate.

[0032] As a further explanation of this embodiment, the rotation of the spindle 11 drives the rotational molding die 12 to rotate synchronously.

[0033] In this embodiment, a pulse air pump 14 is installed on one side of the top of the hanger 4, and the pulse air pump 14 is connected to the pneumatic slip ring 13 via a pipe; the pneumatic slip ring 13 is connected to the interior of the main shaft 11, and the main shaft 11 is connected to the interior of the rotational molding mold 12.

[0034] More specifically, the pneumatic slip ring 13 connects the pulse air pump 14, the main shaft 11 and the rotational molding die 12 without affecting the rotation of the main shaft 11. The interior of the main shaft 11 is a hollow structure.

[0035] As a further explanation of this embodiment, during demolding, air is injected into the interior of the rotational molding mold 12 by the pulse air pump 14 to help push the product out of the rotational molding mold 12.

[0036] In this embodiment, each of the rotating shafts 5 is equipped with an adapter 6 at its end, and each adapter 6 is equipped with a gas pipe 7; each of the gas pipes 7 is equipped with three sets of flame pipes 8 at equal intervals, and each set of flame pipes 8 has four flame pipes at equal intervals.

[0037] More specifically, adapter 6 needs to be connected to the gas supply pipeline during use, and a valve is provided at the connection between adapter 6 and gas pipe 7.

[0038] As a further explanation of this embodiment, the end of the flamethrower tube 8 is in the gap between the upper heat insulation cover 9 and the lower heat insulation cover 10.

[0039] In this embodiment, the upper heat insulation cover 9 and the lower heat insulation cover 10 are respectively disposed on both sides of the rotational molding mold 12, and the inner walls of the upper heat insulation cover 9 and the lower heat insulation cover 10 are both arc-shaped.

[0040] More specifically, the inner walls of both the upper insulation cover 9 and the lower insulation cover 10 are mirror-polished to facilitate heat reflection.

[0041] As a further explanation of this embodiment, the upper insulation cover 9 and the lower insulation cover 10 swing synchronously with the movable frame 3.

[0042] The working principle of this utility model is as follows: In use, the raw material is first placed inside the rotational molding mold 12, then the rotational molding mold 12 is closed, and the two adapters 6 are simultaneously connected to the gas supply pipe. After the gas passes through the gas pipe 7, it is sprayed out through the flame pipe 8. At this time, all the flame pipes 8 are ignited. Then, the external power supply is connected, the first motor 15 is started, and the main shaft 11 is driven to rotate, which in turn drives the rotational molding mold 12 to rotate synchronously. Then, the second motor 16 is started, and the movable plate 17 is driven to rotate slowly. At the same time, the connecting rod 18 drives the movable frame 3 to swing up and down continuously, which in turn drives the rotational molding mold 12 to swing up and down synchronously. With the rotation of the rotational molding mold 12, the raw material can be evenly distributed on the inner wall of the rotational molding mold 12. Then, the gas supply is turned off, and the raw material is allowed to solidify naturally. After the rotational molding mold 12 cools down, the rotational molding mold 12 is opened, the pulse air pump 14 is started, and air is injected into the interior of the rotational molding mold 12 in conjunction with the pneumatic slip ring 13 and the main shaft 11, pushing the product out of the rotational molding mold 12.
