Description

Technical Field

[0001] The utility model relates to the field of blow molding molds, and particularly relates to a blow molding mold for medicine bottles. Background Art

[0002] Compared with products such as stacking barrels and laundry detergent bottles, the volume of medicine bottles is relatively small. And the cost of making a blow molding mold that exactly matches the volume of medicine bottles is relatively high. If multiple medicine bottles can be blow molded simultaneously, it can not only reduce costs but also improve processing efficiency. Therefore, there is a need for a blow molding mold for medicine bottles with a simple structure, relatively low cost, capable of blow molding multiple medicine bottles simultaneously and cutting multiple medicine bottles simultaneously. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a blow molding mold for medicine bottles with a simple structure, relatively low cost, capable of blow molding multiple medicine bottles simultaneously and cutting multiple medicine bottles simultaneously.

[0004] The utility model provides a blow molding mold for medicine bottles, which includes a front back plate, a rear back plate, a main mold, a sub - mold and a flash trimming device. The main mold includes a first main mold and a second main mold, and the sub - mold includes a first sub - mold and a second sub - mold.

[0005] The first main mold and the first sub - mold are fixedly connected to the front back plate, the second main mold and the second sub - mold are fixedly connected to the rear back plate, and the flash trimming device is arranged on the rear side of the second sub - mold and fixedly connected to the rear back plate.

[0006] At least one forming cavity is respectively arranged in the first main mold and the second main mold. The forming cavity includes an inlet cavity communicated with the outside at the top, a flow - dividing cavity arranged at the bottom of the inlet cavity, and a bottle body generating cavity arranged at the bottom of the flow - dividing cavity.

[0007] Preferably, a baffle is arranged at the position where the flow - dividing cavity faces the inlet cavity. By arranging the baffle, the qualified rate of processing can be higher.

[0008] Preferably, the forming cavity further includes a lower generating cavity arranged at the bottom of the bottle body generating cavity.

[0009] Preferably, the flash trimming device includes a first pushing plate, a second pushing plate, a pushing cylinder, a connecting rod, a trimming knife and a connecting piece.

[0010] The pushing cylinder is arranged outside the back plate and fixedly connected to the back plate. The connecting piece is arranged around the pushing cylinder and fixedly connected to the back plate. A connecting rod through hole through which the connecting rod can pass is arranged in the middle of the connecting piece. Both ends of the connecting rod are respectively connected to the first pushing plate and the second pushing plate. The first pushing plate is arranged outside the back plate and connected to the output shaft of the pushing cylinder. The second pushing plate is arranged inside the back plate, and a cutting knife is arranged on the second pushing plate.

[0011] The pushing cylinder drives the first pushing plate to move, thereby driving the second pushing plate to move and cutting off the sprue material through the cutting knife.

[0012] The beneficial effects of the blow molding die for medicine bottles of the present utility model are as follows:

[0013] 1. Compared with the forming cavity of a conventional blow molding die, by providing a flow splitting cavity, the wall thickness of the medicine bottles blown out from each individual bottle body forming cavity can be ensured to be consistent.

[0014] 2. By providing a baffle at the position of the flow splitting cavity facing the inlet cavity, the processing yield can be made higher by setting the baffle. Description of the Drawings
