Description

Technical Field

[0001] This utility model relates to the field of plastic blow molding technology, specifically to a multi-sided cooling mechanism for blow molding double-sided plastic trays. Background Technology

[0002] Double-sided plastic pallets are a common type of pallet structure. As the name suggests, a double-sided pallet can be used on both sides. Compared to other pallet structures, the primary function of double-sided plastic pallets is for stacking goods. Double-sided pallets are most widely used in the chemical industry, and they are generally produced through blow molding.

[0003] However, in the production process of existing double-sided plastic pallets, the molds used are generally cooled by setting cooling plates on both sides of the mold, which results in low cooling efficiency.

[0004] Therefore, we propose a multi-sided cooling mechanism for blow molding double-sided plastic trays. Utility Model Content

[0005] The purpose of this invention is to provide a multi-sided cooling mechanism for blow molding double-sided plastic trays to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-sided cooling mechanism for blow-molded double-sided plastic trays, comprising a base, a fixed partition plate fixedly installed on the top of the base, a compressor fixedly installed inside the base, a cooling plate fixedly installed on the top of the fixed partition plate, an electric push rod fixedly installed on the top of the fixed partition plate, a lifting plate fixedly installed on the top of the electric push rod directly above the fixed partition plate, an upper cooling plate fixedly installed on the bottom of the lifting plate directly above the cooling plate, a rotating bracket rotatably connected to the opposite surfaces of the fixed partition plate and the lifting plate, a side cooling plate rotatably connected to the other end of the rotating bracket, a guide coil laid inside the upper cooling plate, the lower cooling plate and the side cooling plate, and elastic hoses fixedly installed at the inlet and outlet of the compressor. One end of the guide coil is connected to the elastic hose fixedly installed at the outlet of the compressor, and the other end of the guide coil is connected to the elastic hose fixedly installed at the inlet of the compressor.

[0007] Optionally, the base is equipped with a cooling device for the compressor, and the compressor's inlet and outlet are fixedly installed through the fixed partition.

[0008] Optionally, the rotating bracket includes a first support rod rotatably connected to the outer side of the side cooling plate. The other end of the first support rod is provided with a movable groove. A telescopic rod is slidably connected inside the movable groove. The other ends of the two telescopic rods are rotatably connected to the opposite surfaces of the fixed partition and the lifting plate, respectively.

[0009] Optionally, the two first support rods are rotatably connected to the middle of the outer side of the side cooling plate, and the two first support rods are symmetrically arranged on the outer side of the side cooling plate.

[0010] Optionally, a buffer spring is provided inside the movable groove. One end of the buffer spring is fixedly installed to the bottom of the movable groove, and the other end of the buffer spring is fixedly installed to one end of the telescopic rod located inside the movable groove.

[0011] Optionally, a limiting frame is fixedly installed on the top of the cooling plate. The size of the limiting frame is the same as that of the mold. The upper cooling plate, the lower cooling plate, the side cooling plate, and the guide coil are made of the same material. The two side cooling plates are symmetrically arranged on both sides of the limiting frame.

[0012] Optionally, the four electric push rods are fixedly installed at the four corners of the top of the fixed partition, and the tops of the four electric push rods are fixedly installed at the four corners of the bottom of the lifting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This multi-sided cooling mechanism for blow molding double-sided plastic trays uses an upper cooling plate, a lower cooling plate, side cooling plates, and a guide coil. The blow molding mold is placed in a limiting frame, and the electric push rod retracts, causing the lifting plate to descend. At the same time, it pushes the rotating bracket to deflect, pushing the side cooling plate to press against the side of the mold. The temperature of the upper cooling plate, lower cooling plate, and side cooling plate is reduced through the elastic hose and guide coil, thereby cooling multiple sides simultaneously and increasing the cooling efficiency of the mold.

[0015] 2. This multi-sided cooling mechanism for blow molding double-sided plastic pallets uses rotating brackets. When the lifting plate rises, the two symmetrically arranged rotating brackets deflect, pulling the side cooling plate away from the mold. When the lifting plate descends, after the side cooling plate is pressed against the mold, the telescopic rod retracts as the lifting plate descends, preventing the excessively long rotating brackets from breaking.

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.

[0021] Please see Figures 1 to 3 This utility model provides a multi-sided cooling mechanism for blow-molded double-sided plastic trays, including a base 1, a fixed partition 2 fixedly installed on the top of the base 1, a compressor 3 fixedly installed inside the base 1, a cooling plate 4 fixedly installed on the top of the fixed partition 2, an electric push rod 5 fixedly installed on the top of the fixed partition 2, a lifting plate 6 fixedly installed on the top of the electric push rod 5 directly above the fixed partition 2, an upper cooling plate 9 fixedly installed on the bottom of the lifting plate 6 directly above the cooling plate 4, a rotating bracket 7 rotatably connected to the opposite surfaces of the fixed partition 2 and the lifting plate 6, and a side cooling plate 8 rotatably connected to the other end of the rotating bracket 7. A guide coil 11 is laid inside the upper cooling plate 9, the lower cooling plate 4, and the side cooling plate 8. The compressor 3 has a flexible hose 10 fixedly installed at its inlet and outlet. One end of the guide coil 11 is connected to the flexible hose 10 fixedly installed at the outlet of the compressor 3, and the other end of the guide coil 11 is connected to the flexible hose 10 fixedly installed at the inlet of the compressor 3. By setting up the upper cooling plate 9, the lower cooling plate 4, the side cooling plate 8 and the guide coil 11, the blow molding mold is placed into the limiting frame 12. The electric push rod 5 retracts, causing the lifting plate 6 to descend. At the same time, it pushes the rotating bracket 7 to deflect, pushing the side cooling plate 8 to stick tightly to the side of the mold. The temperature of the upper cooling plate 9, the lower cooling plate 4 and the side cooling plate 8 is reduced through the flexible hose 10 and the guide coil 11, thereby cooling multiple sides at the same time and increasing the cooling efficiency of the mold.

[0022] The base 1 is equipped with a cooling device for the compressor 3. The inlet and outlet of the compressor 3 are fixedly installed through the fixed partition 2. The rotating bracket 7 includes a first support rod 71 rotatably connected to the outer side of the side cooling plate 8. The other end of the first support rod 71 has a movable groove 72. The movable groove 72 is slidably connected to a telescopic rod 73. The other ends of the two telescopic rods 73 are rotatably connected to the opposite surfaces of the fixed partition 2 and the lifting plate 6, respectively. The two first support rods 71 ​​are rotatably connected to the middle of the outer side of the side cooling plate 8. The two first support rods 71 ​​are symmetrically arranged on the outer side of the side cooling plate 8. The movable groove 72 is equipped with a buffer spring 74. One end of the buffer spring 74 is fixedly installed to the bottom of the movable groove 72. The other end of the buffer spring 74 is located at the telescopic rod 73. One end of the movable groove 72 is fixedly installed. By setting a rotating bracket 7, when the lifting plate 6 rises, the two symmetrically arranged rotating brackets 7 deflect, pulling the side cooling plate 8 to separate from the mold. When the lifting plate 6 falls, after the side cooling plate 8 is pressed against the mold, the telescopic rod 73 of the lifting plate 6 retracts as it falls, preventing the excessively long rotating bracket 7 from breaking. A limit frame 12 is fixedly installed on the top of the cooling plate 4. The size of the limit frame 12 is the same as the size of the mold. The upper cooling plate 9, the cooling plate 4, the side cooling plate 8 and the guide coil 11 are made of the same material. The two side cooling plates 8 are symmetrically arranged on both sides of the limit frame 12. Four electric push rods 5 are fixedly installed at the four corners of the top of the fixed partition plate 2, and the tops of the four electric push rods 5 are fixedly installed at the four corners of the bottom of the lifting plate 6.

[0023] Working principle:

[0024] When the blow molding mold is placed in the limiting frame 12, the electric push rod 5 retracts, causing the lifting plate 6 to descend. At the same time, it pushes the rotating bracket 7 to deflect, pushing the side cooling plate 8 to press against the side of the mold. The temperature of the upper cooling plate 9, the lower cooling plate 4, and the side cooling plate 8 is reduced through the elastic hose 10 and the guide coil 11, thereby cooling multiple sides simultaneously and increasing the cooling efficiency of the mold. By setting the rotating bracket 7, when the lifting plate 6 rises, the two symmetrically set rotating brackets 7 deflect, pulling the side cooling plate 8 to separate from the mold. When the lifting plate 6 descends, after the side cooling plate 8 presses against the mold, the telescopic rod 73 retracts as the lifting plate 6 descends, preventing the excessively long rotating bracket 7 from breaking.
