Description

Technical Field

[0001] This utility model relates to the field of plastic bottle technology, and in particular to a plastic bottle ejection mold. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperature and then molded into plastic containers through blow molding, extrusion blow molding and or injection molding. They are mainly used as disposable plastic packaging containers for liquids or solids such as beverages, food, pickles, honey, dried fruit, edible oil and agricultural and veterinary drugs. Plastic bottles have the characteristics of being not easily broken, low cost, high transparency and food-grade raw materials.

[0003] Plastic bottles, as a common packaging material in daily life, are widely used in beverages, food, cosmetics and many other fields. The production of plastic bottles usually adopts the injection molding process, which includes steps such as heating, injection, cooling and demolding of plastic materials. However, it has been found in the use of existing plastic bottle ejection molds that mostly use mechanical ejection. The ejection force is often insufficient to cope with thick-walled plastic bottles, resulting in demolding difficulties and even damage to the plastic bottles. To address this issue, we propose a plastic bottle ejection mold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a plastic bottle ejection mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plastic bottle ejection mold includes a fixed plate, two support seats fixedly connected to the bottom surface of the fixed plate, a positioning frame fixedly connected to the upper surface of the fixed plate, an electric push rod fixedly mounted on the upper surface of the positioning frame, an adjusting plate fixedly connected to the telescopic ends of the two electric push rods, a fixing block fixedly connected to the upper surface of the fixed plate, an injection tube connected to the bottom surface of the fixing block and the bottom surface of the fixed plate, a positioning mold fixedly connected to the upper surface of the adjusting plate, an annular arrangement of ejection holes on the upper surface of the positioning mold, a connecting seat fixedly connected to the inner top wall of the positioning frame, an annular arrangement of ejection rods fixedly connected to the bottom surface of the connecting seat, two guide grooves on the inner side wall of the positioning frame, a guide block slidably connected inside each guide groove, and the sides of the two guide blocks that are close to each other fixedly connected to the left and right sides of the adjusting plate, respectively.

[0007] In a further embodiment, a reinforcing ring is fixedly connected to the outer surface of each of the electric push rods, and the bottom end of each reinforcing ring is fixedly connected to the upper surface of the positioning frame.

[0008] In a further embodiment, two sets of stabilizing plates are fixedly connected to the upper surface of the fixing plate, and the sides of the two sets of stabilizing plates that are close to each other are fixedly connected to the left and right sides of the positioning frame, respectively.

[0009] In a further embodiment, a stabilizing frame is fixedly connected to the outer surface of the positioning mold, and the bottom surface of the stabilizing frame is fixedly connected to the upper surface of the adjusting plate.

[0010] In a further embodiment, the upper surface of the adjusting plate is provided with two sets of sliding holes, and a sliding rod is slidably connected inside each sliding hole. The top end of each sliding rod is fixedly connected to the inner bottom wall of the positioning frame, and the bottom end of each sliding rod is fixedly connected to the upper surface of the fixing plate.

[0011] In a further embodiment, two reinforcing wedges are fixedly connected to the bottom surface of the fixing plate, and the two reinforcing wedges are fixedly connected to the sides of the support base that are close to each other on opposite sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses the cooperation of an electric push rod, an adjusting plate, a guide block, and a guide groove to position the adjusting plate. It also utilizes the cooperation of a sliding hole and a sliding rod to achieve the same positioning, ensuring the ejector rod is inserted into the ejector hole. Because the ejector rods are arranged in a circular pattern, they effectively eject thick-walled plastic bottles, preventing damage during ejection. This effectively solves the problem that mechanical ejection often lacks sufficient ejection force for thick-walled plastic bottles, leading to demolding difficulties or even damage.
