Problems solved by technology

[0003] When the existing blow molding mold is in use, during the blow molding process of the blank, due to the excessive pressure of the blown air flow, the hollow is easy to fit closely with the blow molding cavity, resulting in the phenomenon that the formed hollow container is inconvenient to take out. However, the existing blow molds for blow molding hollow containers do not have the function of automatic mold ejection. In view of this, we provide a blow mold for blow molding hollow containers

Embodiment 1

[0025] see Figure 1-5 , a blow mold for blow molding a hollow container, comprising a base 1 and two symmetrical molds 2 that cooperate with each other, the top surface of the base 1 is fixedly connected with a first slide rail 3, and one of the molds 2 is fixed Connected to the base 1, the other mold 2 is slidably connected to the first slide rail 3 through a moving mechanism, the two molds cooperate to form a blow molding cavity 4, and the adjacent surfaces of the two molds 2 are provided with mutual cooperation The connecting rod 12 and the connecting hole 13, the blow molding cavity 4 is provided with a mold ejection mechanism, the tops of the two molds 2 cooperate to form a blowing port 5, and the bottoms of the two molds 2 cooperate to form a blowing port 6, The air blowing port 5 communicates with the blow molding cavity 4 through the air inlet pipe 7, the blow molding port 6 communicates with the blow molding pipe 8 provided in the base 1, and the air inlet pipe 7 is ...

Embodiment 2

[0031] This embodiment describes the stabilization mechanism in detail on the basis of Embodiment 1, specifically:

[0032] Described stabilizing mechanism comprises movable block 21, and described movable block 21 is sealed and slidably connected in the intake duct 7, and the top of movable block 21 is connected with intake duct 7 by tension spring 22, and there are many A vent hole 23, the side of the air inlet pipe 7 is provided with a plurality of air outlet pipes 24 communicating with it, by setting a stabilizing mechanism, the airflow blowing into the blow molding cavity 4 plays a role in stabilizing the airflow, so that the blowing The wall thickness of the molded hollow container is uniform without flash, which further improves the quality of the molded hollow container. When the air flow rate is too high, the tension spring 22 is stretched downward, so that the air inlet pipe 7 is connected with the air outlet pipe 24 Through, thereby reducing the effect of the airflo...

Abstract

The invention relates to the technical field of plastic product processing, in particular to a blowing mold for blow molding of a hollow container. The blowing mold comprises a base and two symmetrical molds matched with each other, the two molds are matched to form a blow molding cavity, a mold stripping mechanism is arranged in the blow molding cavity and connected with a reset mechanism; the tops of the two molds are matched to form an air blowing opening, the air blowing opening communicates with a blow molding pipeline arranged in the base, a stabilizing mechanism is arranged in the air inlet pipeline, and by arranging the mold stripping mechanism and the reset mechanism, the automatic mold stripping effect is achieved, in addition, fluid transmission is adopted in the reset mechanism, and therefore reset stability is guaranteed, and the mold stripping effect of the hollow container is further improved; and by arranging the stabilizing mechanism, the effect of stabilizing airflow blown into the blow molding cavity is achieved, so that the wall thickness of the blow-molded hollow container is uniform, no flash exists, and the quality of the molded hollow container is further improved.

Description

technical field [0001] The invention relates to the technical field of plastic product processing, in particular to a blow mold for blow molding hollow containers. Background technique [0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of the hollow container can reach thousands of liters, and some production has adopted computer control. [0003] When the existing blow molding mold is in use, during the blow molding process of the blank, due to the excessive pressure of the blown air flow, the hollow is easy to fit closely with the blow molding cavity, resulting in the phenomenon that the formed hollow container is inconvenient to take out. However...
