Description

Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a cooling device in a blow molding mold. Background Technique

[0002] The blow molding mold can process tubular workpieces. During the processing, the cooling device inside the mold can cool the inside of the mold to improve the effect of quickly cooling the formed workpiece.

[0003] In order to cool the mold, a cooling cavity is formed inside the mold. A cooling pipe is installed inside the cooling cavity opened inside the mold, and one end of the cooling pipe is connected to an external coolant tank. The coolant tank provides coolant for the inside of the cooling pipe, and then the inside of the mold can be cooled through the cooling pipe to achieve the cooling effect on the formed workpiece.

[0004] In the actual use process, since the internal cooling pipes are usually distributed on one side of the inside of the mold, it is not convenient to distribute them according to the shape of the shaping cavity of the formed workpiece. As a result, the temperature of some positions of the shaping cavity inside the mold drops slowly. At the same time, only using the cooling pipes to cool the inside of the mold makes the cooling slower, thus reducing the cooling effect on the inside of the mold. In view of the deficiencies of the prior art, we propose a cooling device in a blow molding mold to solve the above problems. Content of the Utility Model

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] An embodiment of the present utility model discloses a cooling device in a blow molding mold.

[0024] According to the attached Figure 1-6 As shown, it includes a mold body 1, the mold body 1 is composed of a moving die 101 and a fixed die 102. The inner parts of the moving die 101 and the fixed die 102 are both provided with shaping cavities. Cooling units 2 are arranged inside the mold body 1. A water tank 202 is arranged outside the mold body 1. The cooling unit 2 includes cooling pipes installed inside the mold body 1. The cooling pipes are composed of a bow-shaped tube 205 and a bow-shaped side tube 207. The bow-shaped side tube 207 is located on one side of the bow-shaped tube 205. The bow-shaped side tube 207 is located outside the shaping cavity. The bow-shaped tube 205 is located on the outer walls of both sides of the shaping cavity. The bow-shaped side tube 207 and the bow-shaped tube 205 form a framework to wrap the shaping cavity. The heights of the bow-shaped side tube 207 and the bow-shaped tube 205 are the same as the height of the shaping cavity. Before use, the cooling unit 2 and the mold body 1 are installed through the mounting plate 3, so that the cooling pipes and the cooling fan 304 are installed inside the mold body 1 to quickly cool the formed workpiece.

[0025] The water inlet and outlet of the cooling pipe are connected to the water tank 202. A cooling fan 304 is provided on one side of the cooling pipe. The cooling fan 304 cools the inside of the mold body 1. The outer wall of the mold body 1 is provided with a mounting plate 3. The cooling fan 304 and the cooling pipe are installed with the mold body 1 through the mounting plate 3. When shaping the workpiece, the movable mold 101 fits with the fixed mold 102, so that the blow molding head of the blow molding machine is inserted into the inside of the shaping cavity at the top of the mold body 1 to blow the material, so that the mold body 1 is close to the workpiece. The workpiece is shaped, and then the water pump 203 is started to allow the coolant in the water tank 202 to enter from one end of the bow-shaped tube 205 through the water inlet pipe 204, and the coolant is transmitted to the inside of the bow-shaped side tube 207 in turn through the bottom end of the bow-shaped tube 205. The coolant in the bow-shaped tube 205 and the bow-shaped side tube 207 is used to cool the inside of the shaping cavity, thereby achieving rapid cooling of the workpiece. At the same time, the cooling fan 304 can be used to dissipate heat inside the mold body 1 to ensure the use of the cooling tube.

[0026] A cooling cavity 201 is formed on one side of the interior of the mold body 1, and a bow-shaped tube 205 is installed inside the cooling cavity 201. Side cooling cavities 1011 are opened on both sides of the interior of the mold body 1. Bow-shaped side tubes 207 are located inside the side cooling cavity 1011. By combining the bow-shaped tube 205 with the bow-shaped side tubes 207 on the side, the combined bow-shaped tube 205 and the bow-shaped side tubes 207 can form a frame form and be distributed around the molding cavity. The side and outer side of the molding cavity can be cooled, thereby improving the rapid cooling effect of the formed workpiece.

[0027] The two ends of the multiple groups of bow-shaped side tubes 207 are respectively connected to the top and bottom ends of the bow-shaped tube 205, and the two ends of the bow-shaped tube 205 are respectively fixedly connected with the water inlet pipe 204 and the water outlet pipe 206. The ends of the water inlet pipe 204 and the water outlet pipe 206 pass through the inner wall of the mold body 1 to be connected to the water tank 202. After long-term use, the internal cooling pipe and the cooling fan 304 need to be repaired and replaced. By removing the fixing bolts 302 from the mounting plate 3 and the inside of the mold body 1, the mounting plate 3 drives the internal cooling pipe and the cooling fan 304 to detach from the inside of the mold body 1, which facilitates the maintenance of the internal cooling unit 2.

[0028] A water pump 203 is provided on one side of the water tank 202, and the water outlet of the water pump 203 is connected to one end of the water inlet pipe 204. A plurality of sets of fixing bolts 302 are provided on the outer wall of the mounting plate 3, and the plurality of sets of fixing bolts 302 are all threadedly connected to the inside of the mounting plate 3 and the mold body 1. Water is introduced through the water inlet pipe 204, so that the coolant passes through various places of the bow-shaped tube 205 and the bow-shaped side tube 207 in turn, and then is discharged to the inside of the water tank 202 through the water outlet pipe 206 to achieve the purpose of circulation.

[0029] A dust-proof net 303 is provided in the middle of the mounting plate 3. The cooling fan 304 is installed on the inner wall of the mounting plate 3. The outer wall of the bow-shaped pipe 205 is fixedly installed with the mounting plate 3 through a fixing rod 301.
