Description

Technical Field

[0001] This utility model relates to the field of heating technology, specifically to a simple heating box structure. Background Technology

[0002] An injection molding machine is a device used to process plastic products. It injects heated plastic raw materials into an injection mold through an injection port. The raw materials flow naturally and fill the injection mold completely. After that, the raw materials are cooled, and the cooled plastic raw materials form the product shape, thus completing the injection molding process.

[0003] During the injection molding process, because plastic products have a certain degree of stickiness, some raw materials of the plastic product may remain inside the mold. If the raw materials are not cleaned in time, they will affect the subsequent processing of the product, such as affecting the integrity of the product or making the appearance uneven.

[0004] The existing method is to use a high-pressure air gun to forcefully blow away residual adhesive on the mold. However, the high-pressure air gun blows out cold or room-temperature air, which lowers the temperature of the residual adhesive, resulting in poor flowability and making it difficult to remove the adhesive quickly and effectively, especially for stubborn adhesive. It also lowers the mold temperature, which may affect the quality and molding effect of the injection molded product. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a simple heating box structure with a reasonable structural design that can heat gas and improve the effect of blowing away residual adhesive from molds.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A simple heating box structure includes a box body, a bakelite board, a partition, an air inlet pipe, an air outlet pipe, and a gas storage heating tank. The partition is disposed in the box body such that the upper part of the box body forms a heating chamber and the lower part forms a control chamber. The opening of the heating chamber faces upward, and the bakelite board is used to seal the opening. The gas storage heating tank is disposed in the heating chamber. The air inlet pipe and the air outlet pipe both extend into the heating chamber and are connected to the gas storage heating tank.

[0008] In a preferred embodiment of this utility model, the gas storage heating tank includes a tank body, an air-drying electric heating tube, a through-plate connector, and a bend connector. The opening of the tank body faces upward, and the opening of the tank body is provided with a mounting flange. The mounting flange is tightly attached to the lower surface of the bakelite board and locked with screws, so that the entire tank body can be stably installed in the heating chamber and ensures airtightness. The interface end of the air-drying electric heating tube is located on the bakelite board, and the heating end extends into the tank body. The through-plate connector is installed on the bakelite board corresponding to the opening position of the tank body, and the lower end of the through-plate connector is connected to the tank body. One end of the bend connector is located at the lower part of the tank body, and the other end faces the bakelite board. The air-drying electric heating tube can quickly heat the gas flowing through the tank body.

[0009] In a preferred embodiment of this invention, two air-drying electric heating tubes are located on either side of the through-plate connector. This ensures that the gas is heated evenly within the tank, improving heating efficiency.

[0010] In a preferred embodiment of this invention, one end of the air inlet pipe is connected to the upper end of the through-plate connector. This allows external gas to smoothly enter the heating tank and undergo heating treatment.

[0011] As a preferred embodiment of this utility model, one end of the air outlet pipe is connected to the other end of the bent pipe joint, and the other end of the air outlet pipe passes vertically upward through the bakelite board, so as to facilitate the delivery of heated gas to the high-pressure air gun.

[0012] As a preferred embodiment of this utility model, a sealing gasket is provided between the mounting flange and the lower surface of the bakelite board to ensure that the gas inside the tank will not leak, thus maintaining heating efficiency and safety.

[0013] As a preferred embodiment of this utility model, the heating cavity is filled with heat-insulating material, which has a good heat-insulating effect and can reduce heat loss.

[0014] As a preferred embodiment of this utility model, the bottom surface of the box is provided with foot plates at each of the four corners, and the foot plates are provided with mounting holes. This facilitates the stable installation of the entire heating box structure in the required position, while ensuring the stability and safety of the structure.

[0015] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design. It is connected to the blowing air circuit through the air inlet pipe and the air outlet pipe. The gas is first heated in the gas storage and heating tank, and then transmitted to the high-pressure air gun through the air outlet pipe. The high-pressure air gun can blow out hot gas, which can cause the residual glue to expand due to heat and improve the fluidity of the residual glue, which helps to separate the residual glue from the mold surface, making it easier to blow away. The blowing effect is good, and it is also conducive to maintaining the mold temperature, ensuring the quality and molding effect of the injection molded product. In addition, the overall structure is simple and compact, easy to manufacture, low in cost, and the gas heating speed is fast, which is conducive to its widespread use.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] Figure 3 This is an exploded structural diagram of the present invention. Detailed Implementation

[0020] See Figure 1 , Figure 2 and Figure 3 This embodiment provides a simple heating box structure, which includes a box body 1, a bakelite board 2, a partition 3, an air inlet pipe 4, an air outlet pipe 5, and a gas storage heating tank 6.

[0021] The partition 3 is set inside the box 1 so that the upper part of the inner cavity of the box 1 forms a heating cavity 11 and the lower part forms a control cavity 12. The control cavity 12 is used to install electronic components such as controllers and thermometers to avoid the influence of high temperature.

[0022] Foot plates 13 are provided at the four corners of the bottom surface of the housing 1, and mounting holes are provided on the foot plates 13. This facilitates the stable installation of the entire heating box structure in the required position, while ensuring the stability and safety of the structure. Handles 7 are symmetrically provided on both sides of the bakelite board 2 for easy movement.

[0023] The opening of the heating chamber 11 faces upward, and the bakelite board 2 seals the opening. The gas storage heating tank 6 is disposed inside the heating chamber 11, and both the inlet pipe 4 and the outlet pipe 5 extend into the heating chamber 11 and are connected to the gas storage heating tank 6. Specifically, the gas storage heating tank 6 includes a tank body 61, an air dry-burning electric heating tube 62, a through-plate connector 63, and a bend connector 64. The opening of the tank body 61 faces upward, and the opening of the tank body 61 is provided with a mounting flange 611. The mounting flange 611 is tightly attached to the lower surface of the bakelite board 2 and locked with screws 65, so that the entire tank body 61 can be stably installed in the heating chamber 11 and ensure airtightness. To ensure that the gas inside the tank body 61 does not leak, a sealing gasket 66 can be provided between the mounting flange 611 and the lower surface of the bakelite board 2. The interface end of the air-drying electric heating tube 62 is disposed on the bakelite board 2, and the heating end extends into the tank 61. The air-drying electric heating tube 62 can quickly heat the gas flowing through the tank 61. Preferably, there are two air-drying electric heating tubes 62, located on both sides of the through-plate connector 63, which can ensure that the gas is heated evenly in the tank 61 and improve heating efficiency. In other embodiments, the number of air-drying electric heating tubes 62 can also be set according to the required heating speed and power. Insulation material can also be filled in the heating chamber 11, which has a good insulation effect and can reduce heat loss.

[0024] The through-plate connector 63 is installed on the bakelite board 2 corresponding to the opening of the tank 61, and the lower end of the through-plate connector 63 is connected to the tank 61. One end of the air inlet pipe 4 is connected to the upper end of the through-plate connector 63. This allows external gas to smoothly enter the heating tank and be heated. One end of the bent pipe connector 64 is located at the lower part of the tank 61, and the other end faces the bakelite board 2. One end of the air outlet pipe 5 is connected to the other end of the bent pipe connector 64, and the other end of the air outlet pipe 5 passes vertically upward through the bakelite board 2, facilitating the delivery of heated gas to the high-pressure air gun.

[0025] Before use, the air inlet pipe 4 is connected to the air outlet of the air supply pump, and the air outlet pipe 5 is connected to the high-pressure air gun through a pipeline. During operation, the gas blown out by the air supply pump enters the air storage heating tank 6 for heating, and then is transmitted to the high-pressure air gun through the air outlet pipe 5, so that the high-pressure air gun can blow out hot air. The hot air can cause the residual glue to expand due to heat and improve the fluidity of the residual glue, which helps to separate the residual glue from the mold surface, making it easier to blow away. The blowing effect is good, and it also helps to maintain the mold temperature, ensuring the quality and molding effect of the injection molded products.
