Multi-hole bottle blowing mold

Abstract

The utility model provides a blow molding mold for a porous bottle. A blow-molded bottle body is a porous bottle with multiple holes. The porous bottle is used for containing fishing bait and other occasions where materials needing to be contained can leak out. A hole cutter is mounted on the wall of a cavity of the blowing mold and protrudes out of the wall of the cavity. And when the heated and softened bottle material is blown in the cavity until the bottle blank is in contact with the hole cutter, under the pushing of air pressure, the bottle blank is cut into a hole with the same shape as the cutting edge of the hole cutter by the cutting edge of the hole cutter. At the moment, the air inlet and outlet channel behind the material pushing plug is in an air exhausting state, and the cut hole material is pushed to the rear cavity of the hole cutter along with the material pushing plug. Due to the fact that the outer surface of the cutting edge of the hole cutter is high in smoothness and has taper, sealing between the cutting edge and the edge of a cut bottle blank hole is good, the bottle blank is continuously blown to be large and tightly attached to the cavity wall, and a porous bottle is formed. And shaping the porous bottle after water cooling. At the moment, the air inlet and outlet passage behind the material pushing plug is switched into an air inlet state, and the material pushing plug pushes the cut hole materials into the porous bottle under the pushing of air pressure and is discharged from the mold to be recycled along with the porous bottle.

Description

Technical Field

[0001] The utility model relates to a porous bottle blow molding mold. Background Art

[0002] The existing bottle body blow molding mold is used to blow the bottle material into a closed container with a bottle mouth. Utility Model Content

[0003] The existing bottle blow molding mold blows a closed container with a bottle mouth. In order to make the blow-molded bottle body a porous bottle with multiple holes distributed on the bottle body, the utility model provides a porous bottle blow molding mold. A hole cutter that can cut multiple holes on the blow-molded bottle body is installed in the mold cavity of the blow molding mold, so that the blow-molded bottle body is a porous bottle with multiple holes distributed. When the bottle body is blow-molded, the bottle embryo expands and contacts the edge of the hole cutter protruding from the cavity wall, and multiple holes are cut by the edge of the hole cutter. After cooling and shaping, the blow-molded bottle body is formed into a porous bottle. The porous bottle is used for filling fishing bait and other materials that need to be loaded and can leak out.

[0004] The utility model solves the technical solution of blowing porous bottles with a porous bottle blow molding mold:

[0005] A hole cutter is installed on the cavity of the bottle blow molding mold, with one end of the hole cutter protruding from the cavity wall. When the heated and softened bottle material is blown up in the cavity until the bottle embryo contacts the hole cutter, the bottle embryo is cut out of a hole of the same shape as the hole cutter edge by the hole cutter blade under the push of air pressure. At this time, the air inlet and air outlet duct behind the push plug is in the exhaust state, and the cut hole material is pushed to the rear cavity of the hole cutter along with the push plug. Because the outer surface of the hole cutter blade is smooth and tapered, it is well sealed with the edge of the cut bottle embryo hole, and the bottle embryo is continued to be blown up, close to the cavity wall, and formed into a porous bottle. After water cooling, the porous bottle is shaped. At this time, the air inlet and air outlet duct behind the push plug is turned into the air intake state. Under the push of air pressure, the push plug pushes the cut hole material into the porous bottle and is recovered with the porous bottle out of the mold.

[0006] The utility model has the beneficial effects of blow-molding the porous bottle, making the hole edges smooth and clean, and having high production efficiency, and the residual materials after hole cutting can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0008] Figure 1 For along Figure 2 The cross-section of the BB line, Figure 2 For along Figure 1 Cross-section along line AA.

[0009] In the figure, 1 is a mold body. The mold body 1 has a mold cavity, an air inlet and outlet channel, and a cooling water channel. 2 is a hole cutter. The hole cutter 2 is installed on the mold cavity 11, perpendicular or approximately perpendicular to the mold cavity wall surface. The shape, size and density of the hole cutter 2 are set according to the shape, size and density of the holes designed for the porous bottle. A cutting edge is opened at one end of the hole cutter 2, and the cutting edge protrudes from the mold cavity wall surface. The other end of the hole cutter 2 limits the extent to which the push plug 13 protrudes from the mold cavity wall surface. 3 is a pressing plate. The pressing plate 3 is equipped with an air inlet and outlet port. The pressing plate 3 presses the air inlet and outlet groove 9 on the top surface of the mold body 1 to form an air inlet and outlet channel. 4 is a sealing gasket. 5 is an exhaust groove. The exhaust groove 5 exhausts the air from the bottleneck during blow molding. 6 is an upper neck mold. The upper neck mold 6 is used to form the bottle mouth thread. 7 is a cutting ring. The cutting ring 7 cuts off the excess bottle material above the bottle mouth during blow molding. 8 is an air inlet and outlet port. 9 is an air inlet and outlet groove. 10 is a water inlet. 11 is a mold cavity. 12 is an air inlet and air outlet. The air inlet and air outlet 12 is connected to the air inlet and air outlet groove 9 through the air inlet and air outlet channel 15 to form an air inlet and air outlet channel. 13 is a push plug. The push plug 13 retreats with the cut hole material during blow molding, and is pushed forward by compressed air after the porous bottle is cooled and shaped, pushing the cut hole material into the porous bottle. 14 is a cooling water channel. The cooling water entering from the water inlet 10 cools the mold body 1 through the cooling water channel 14 and then flows out from the water outlet 17. 15 is an air inlet and air outlet channel. The air inlet and air outlet 15 connects the air inlet and air outlet 12 with the air inlet and air outlet groove 9. 16 is a bottom mold. 17 is a water outlet. 18 is an exhaust groove. The exhaust groove 18 removes air from the middle and lower parts of the mold cavity during blow molding. 19 is a guide column. The guide column 19 is a mold closing guide to accurately position the two half molds when closing the molds. DETAILED DESCRIPTION

[0010] A plurality of hole cutters 2 are installed on the cavity wall of the blow molding mold 1 of the bottle body, and one end of the hole cutter 2 protrudes from the cavity wall of the blow molding mold 1. The end of the hole cutter 2 protruding from the cavity wall of the mold body 1 is cut with a cutting edge. When blow molding a porous bottle, the blow molding mold 1 is closed, and the bottle material enters the cavity. The heated and softened bottle material is blown up in the cavity until the bottle embryo contacts the hole cutter 2. Under the push of air pressure, the bottle embryo is cut out of a hole with the same shape as the cutting edge of the hole cutter 2 by the cutting edge of the hole cutter 2. At this time, the air inlet and outlet passage behind the push plug 13 is in an exhaust state, and the cut hole material is pushed to the rear cavity of the hole cutter 2 along with the push plug 13. Because the outer surface of the cutting edge of the hole cutter 2 is smooth and tapered, it is well sealed with the edge of the cut bottle embryo hole, and the bottle embryo is continued to be blown up, close to the cavity wall of the mold body 1, and formed into a porous bottle. After water cooling, the porous bottle is shaped. At this time, the air inlet and outlet passage behind the push plug 13 is turned into the air inlet state. Under the push of air pressure, the push plug 13 pushes the cut hole material into the porous bottle and is recovered with the porous bottle out of the mold.
