Description

Technical Field

[0001] The utility model relates to the technical field of bottle blowing machines, in particular to a heat preservation structure for a bottle blowing machine mould. Background Art

[0002] A bottle blowing machine refers to a machine that blows bottles. The simplest explanation is that it is a machine that can blow plastic particles (softened into liquid) or finished bottle embryos into bottles through certain process means.

[0003] At present, most of the blow molding machines are still two-step blow molding machines, that is, the plastic raw materials must be made into bottle embryos first, and then blown. Nowadays, environmentally friendly plastics made of PET are generally used. Blow molding machine: After the liquid plastic is sprayed out, the wind blown out by the machine is used to blow the plastic body into a mold cavity of a certain shape to make a product. This machine is called a blow molding machine. It is also a type of blow molding machine, namely a hydraulic blow molding machine.

[0004] The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the parison to inflate the plastic parison and make it adhere tightly to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0005] At present, the bottle blowing machine will first heat the material through a heating box before it enters the mold, and then blow the heated material into shape after entering the mold cavity with high-pressure air. After blow-molding, it needs to be cooled and shaped. The current cooling device uses a water chiller to cool the mold cavity support. The mold cavity is set on the mold cavity support. As long as the temperature on the mold cavity support is low, the temperature in the mold cavity will be low. In this way, the material in the mold cavity can be cooled. The water chiller cools the entire mold cavity support frame through a water channel opened on the mold cavity support frame. The mold cavity temperature must always be kept at a low temperature. Because the temperature of the material blown by high-pressure air is relatively high, and the mold cavity support frame must continue to maintain a low temperature, the water chiller will be restarted every few productions to cool the mold cavity support frame, which will result in considerable energy consumption.

[0006] In order to keep the mold cavity support frame at a low temperature for a long time, a new device is needed to solve the above problems. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] Embodiment 1:

[0026] See also Figures 1 to 3 The utility model provides a heat preservation structure for a blow molding machine mold, comprising: materials and a blow molding machine, the blow molding machine comprising a frame 4, a material heating device, a cooling pool, a water chiller installed in the cooling pool, a transport device for transporting heated materials, a blow molding device installed on the frame 4, a cavity support 1 installed on the support, a water chiller cooling channel 5 provided on the cavity support 1, and a cavity 2 provided on the cavity support 1, the water chiller cooling channel 5 is connected to the cooling pool, and an insulation component for blocking the temperature on the cavity support 1 is provided on the frame 4 or the cavity support 1.

[0027] In this embodiment, the cold air can be effectively retained on the frame 4 or the mold cavity support 1 through the insulation component, so that the temperature of the equipment around the mold cavity 2 can be quickly cooled through the ice water machine cooling channel 5, and the cold air of the frame 4 or the mold cavity support 1 can be effectively prevented from diffusing.

[0028] The heat preservation component comprises a heat insulation plate 3 arranged on a frame 4 or a mold cavity support 1 .

[0029] In this embodiment, a milling cutter can be used to cut the frame 4 or the mold cavity support 1. After cutting, an insulation component is installed at the cut portion of the frame 4 or the mold cavity support 1. The insulation component is an insulation board 3. The insulation board 3 can block the temperature on the frame 4 or the mold cavity support 1, thereby effectively preventing the cold air of the frame 4 or the mold cavity support 1 from diffusing.

[0030] There are two thermal insulation boards 3 which are symmetrical to each other.

[0031] In this embodiment, because the mold cavity support 1 needs to be insulated, generally at least two insulation plates 3 are required to install the insulation plates 3 on both sides of the mold cavity support 1. This installation method will have better insulation and heat preservation effects.

[0032] The number of the thermal insulation board 3 is at least one.

[0033] In this embodiment, when installing the insulation board 3 , a single-layer insulation board 3 or a multi-layer insulation board 3 can be installed to insulate the frame 4 or the mold cavity support 1 .

[0034] The material of the thermal insulation board 3 is a polystyrene board, the material of the thermal insulation board 3 is a bakelite board, and the thermal insulation board 3 is a combination of a polystyrene board and a bakelite board.

[0035] In this embodiment, the insulation board 3 can be made of different materials for heat insulation, and the insulation board 3 can also be made of different combinations of materials to achieve the heat insulation effect.

[0036] Embodiment 2:

[0037] See also Figure 4 As shown, the insulation board 3 is in a U-shape.

[0038] In this embodiment, not only a single insulation board 3 or two symmetrical insulation boards 3 can be used for heat insulation, but the insulation board 3 can also be designed into different shapes, such as a U-shape, with the mold cavity support 1 and the mold cavity 2 inside the U-shape. This can also effectively prevent the cold air from the frame 4 or the mold cavity support 1 from diffusing.

[0039] The specific use of the device is to use a milling cutter to cut the mold cavity bracket 1 or the frame 4, and then place the insulation board 3 at the cutting position;

[0040] When manufacturing the frame 4 and the mold cavity support 1, an insulation component, such as a wooden board, a plastic board, etc., can be set on the contact surface of the frame 4 and the mold cavity support 1, which can save the manufacturing cost of the frame 4 and also insulate the mold cavity support 1.

[0041] Comparison between placing the insulation board 3 and not placing the insulation board 3, the bottle blowing machine without the insulation board 3 needs to cool the mold cavity support 1 by circulating water, and the cooling pool needs to cool twenty times in one hour, so the ice water machine needs to be turned on twenty times;

[0042] With the addition of the insulation board 3, the bottle blowing machine can, under the same conditions, reduce the temperature of the cavity support 1 more quickly when cooling the cavity support 1, because the insulation board 3 can effectively prevent the diffusion of cold air and avoid transmitting excess cold air to the frame 4. Without the insulation board 3, the frame 4 will be cooled together with the cavity support 1. The frame 4 is generally larger, and the air in the factory is generally higher. At this time, the frame 4 will emit cold air. Adding the insulation board 3 can effectively block the cold air and cool down the entire frame 4.

[0043] The specific principle is that the chiller is installed in the cooling pool, and the cooling pool is connected to the chiller cooling channel 5. The entire chiller cooling channel 5 forms a water cycle, so that the mold cavity bracket 1 can be cooled. Because the bottle blowing machine needs to blow the high-calorie material into the corresponding shape, the mold cavity bracket 1 can cool the blown material. The heat of the mold cavity bracket 1 can be brought back to the cooling pool through the water circulation. After a period of time, the circulating water temperature in the cooling pool will increase. At this time, the chiller needs to be turned on to cool the circulating water in the cooling pool. Because the mold cavity bracket 1 is installed on the frame 4, the general frame 4 and the mold cavity bracket 1 They are all metal brackets. At this time, the circulating water cools the cavity bracket 1. Because of the conduction of the metal, the rack 4 will also be cooled. The rack 4 is generally larger, and a large amount of cooling resources will be conducted through the rack 4. In this way, an insulation board 3 is installed on the rack 4 or the cavity bracket 1. This can prevent the cold air from being conducted to the rack 4 and reduce the evaporation of a large amount of cold air from the rack 4. This can extend the time for the circulating water temperature to rise in the cooling pool, so that the opening of the chiller can be reduced. For example, the number of times the chiller is turned on is reduced from twenty times an hour to ten times an hour, which can reduce energy consumption.

[0044] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
