DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a heat dissipation component for mold processing of a blow molding machine. Figure 1-3A heat dissipation component for blow molding machine mold processing includes a blow molding machine die head 2, a blow molding mold 1 is sleeved on the outer side of the blow molding machine die head 2, and a plurality of air flow channels 103 are opened on the blow molding mold 1. The blow molding machine die head 2 includes a die head tube 201 with a partition installed in the middle, and the two sides of the partition on the die head tube 201 are respectively connected with the corresponding cavity 102. The blow molding machine blows air to the blow molding machine die head 2, so that the blowing airflow passes through the air flow channel 103 and flows around the inside of the blow molding mold 1 and then returns to the die head tube 201. The heat exchange between the blowing airflow and the mold realizes air cooling of the mold while preheating the airflow, so that the plastic parison is better formed. A plurality of water cooling components 3 are installed on one side of the blow molding mold 1. The water cooling components 3 are connected with an external coolant supply device to realize the circulation supply of coolant, and the blow molding mold 1 is water-cooled, which cooperates with air cooling to improve the heat dissipation effect.

[0023] Reference Figure 3 A water-cooling cavity 104 is also provided on the outer side of the air flow channel 103 on the mold body 101, and the water-cooling cavity 104 is connected to the water-cooling component 3. A cavity 102 is preset in the middle of the blow mold 1, and the blow mold 1 consists of two cavities 102, wherein a group of air flow channels 103 is located at the connection of the two mold bodies 101, so that the two mold bodies 101 are combined to form a complete air flow channel 103, and two semi-arc grooves are formed by splitting the mold. The air flow channel 103 consists of an inner flow channel and an outer flow channel, and a connecting hole is provided between the inner flow channel and the outer flow channel, and the connecting hole is located at one end of the mold body 101 away from the die head tube 201.

[0024] Reference Figure 2 A partition 202 is installed in the middle of the die head tube 201, and two air pipes 203 are installed at both ends of the partition 202 on the die head tube 201. The air pipe 203 located on one side of the blow molding machine is connected with the corresponding outer flow channel, and the two adjacent outer flow channels are connected with each other. The air pipe 203 located on one side of the mold body 101 is connected with the corresponding inner flow channel, and the two adjacent inner flow channels are connected with each other. Air is blown into the die head tube 201 through the blow molding machine. Due to the blocking of the partition 202, the air enters the outer flow channel, reaches the inner flow channel through the connecting hole and then returns to the die head tube 201, and is blown into the parison from the die head tube 201 to form a plastic blow-molded part. In the middle, the mold body 101 is used to exchange heat with the air to achieve preheating of the air while accelerating the heat dissipation of the blow molding mold 1.

[0025] Reference Figure 1The two water-cooling components 3 each include a three-way pipe 301 installed on the mold body 101, and connecting pipes 302 are installed at both ends of the three-way pipe 301. The ends of the four connecting pipes 302 are installed with guide pipes 303. The four guide pipes 303 are respectively connected to the corresponding two water-cooling chambers 104, and the ends of the two three-way pipes 301 are respectively connected to the coolant outlet and the coolant inlet of the external coolant supply device, so as to realize the circulation supply of coolant to the inside of the water-cooling chamber 104 and liquid cooling of the blow mold 1.

[0026] Reference Figure 3 The connecting pipe 302 is a high-pressure telescopic hose, and the two guide pipes 303 in a water-cooling cavity 104 are respectively located on both sides of the cavity 102.

[0027] The implementation principle of a blow molding machine mold processing heat dissipation component in the embodiment of the present application is:

[0028] The blow molding machine die head 2 starts working and blows air into the die head tube 201. Since a partition 202 is provided in the middle of the die head tube 201, the air is directed to the flow channels on both sides of the partition 202. After flowing through the inside of the mold, the preheated air returns to the die head tube 201 again, and then the air enters the parison through the die head tube 201. During the blow molding process, the air and the mold wall exchange heat. The heat exchange between the air and the mold not only realizes the air cooling and heat dissipation of the mold, but also preheats the airflow, so that the temperature of the air blown into the parison is more suitable, which helps to better mold the plastic parison. At the same time, the water cooling component 3 also plays an important role. The coolant enters the connecting pipe 302 through the three-way pipe 301, and then flows to the guide pipe 303 through the high-pressure telescopic hose, and finally enters the water cooling chamber 104 on the blow molding mold 1. The coolant in the water cooling chamber 104 exchanges heat with the mold wall, absorbs the heat of the mold, and thus realizes liquid cooling and heat dissipation. After absorbing heat, the coolant returns to the coolant supply equipment through the circulation system, where it is cooled and then recycled.
