Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, in particular to a temperature control mechanism for an injection molding machine and the injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is a key equipment that processes thermoplastics or thermosetting plastics into plastic products of various shapes through plastic molding molds. Its types mainly include vertical, horizontal and all-electric types. The functions of the injection molding machine include heating the plastic material, applying high pressure to the molten plastic, and causing it to be injected into and fill the mold cavity.

[0003] In the structure of the injection molding machine, the components configured with a fixed mold include a static mold plate, a movable mold plate, a coring column, and an injection unit. Among them, one end of the coring column is fixed to the static mold plate, and the movable mold plate is designed to be movably mounted on the coring column. The injection unit is located on the side of the static mold plate away from the movable mold plate. Usually, the static mold plate is used to fix the fixed mold part of the mold, while the movable mold plate is used to fix the movable mold part of the mold. When the movable mold plate moves along the coring column, it will drive the movable mold part toward or away from the fixed mold part to complete the opening and closing action of the mold. The function of the injection unit is to guide the molten plastic from the fixed mold part into the mold cavity formed between the movable mold part and the fixed mold part.

[0004] During operation, the injection unit is close to the static mold plate and far away from the dynamic mold plate, which may cause uneven heat transfer to the two mold plates, and then cause the difference in the expansion degree of the static mold plate and the dynamic mold plate. After long-term operation, this uneven thermal expansion and contraction may cause the coring column to bend. Once the coring column bends significantly, it will hinder the smooth movement of the dynamic mold plate on the coring column, seriously restricting the production efficiency and quality of the product.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 to Figure 2 As shown, in this scheme, the application of the temperature control mechanism in the injection molding machine and the specific structure of the temperature control mechanism are mainly described in detail.

[0020] The utility model discloses a temperature control mechanism for an injection molding machine, wherein the injection molding machine comprises a static mold plate 2 and a dynamic mold plate 1, cooling water channels are arranged on the static mold plate 2 and the dynamic mold plate 1, and the cooling water channels are constructed to be laid flat on the dynamic mold plate 1 and the static mold plate 2, and when cooling water flows in the cooling water channels, the temperatures of the dynamic mold plate 1 and the static mold plate are kept consistent.

[0021] During operation, the cooling water system supplies cooling water to these cooling water channels to absorb and take away the heat generated by the static template 2 and the dynamic template 1, thereby not only keeping the temperatures of the two consistent, but also significantly reducing the unbalanced pressure exerted on the guide column due to thermal expansion, effectively preventing the guide column from deforming.

[0022] When the injection molding machine has three templates, namely, a static template 2, a dynamic template 1 and a crankshaft support plate 7, cooling water channels are provided on the static template 2, the dynamic template 1 and the crankshaft support plate 7. The cooling water channels are constructed to be laid flat on the dynamic template 1, the static template 2 and the crankshaft support plate 7. When cooling water flows in the cooling water channels, the temperatures of the dynamic template 1, the static template 2 and the crankshaft support plate 7 are kept consistent.

[0023] Furthermore, the injection molding machine has an injection unit, the static mold plate 2 has a feed portion 3 facing the injection unit, and the cooling water channel on the static mold plate 2 is arranged around the feed portion 3 .

[0024] Feeding area 3 is responsible for guiding the injection unit to accurately dock with the feeding port of the mold. This area receives the most heat and has the most prominent thermal expansion problem, so the annular layout of the cooling water channel can dissipate heat efficiently.

[0025] Preferably, the cooling water channel is formed by a pipe 4 embedded in the static template 2 and the dynamic template 1.

[0026] More specifically, the pipe 4 is embedded in the end faces of the static mold plate 2 and the dynamic mold plate 1 in a winding manner, one side of the pipe 4 along the radial direction is exposed to the outside, and the end face of the side of the pipe 4 exposed to the outside is not higher than the end faces of the static mold plate 2 and the dynamic mold plate 1.

[0027] The pipe 4 is embedded in the end faces of the static template 2 and the dynamic template 1 in a winding manner, aiming to improve the heat dissipation effect by extending the length of the pipe 4 and increasing the contact area. One side edge of the pipe 4 is exposed to facilitate installation operations, while ensuring that its exposed end face is flush with the template end face to prevent interference with other components and protect the pipe from damage.

[0028] A mounting plate 5 is provided on a side of the static template 2 away from the dynamic template 1 , and the pipe 4 is embedded in the mounting plate 5 to realize the installation of the pipe 4 on the static template 2 .

[0029] The mounting plate 5 has a C-shaped shape, with a notch of the mounting plate 5 facing the horizontal direction. The mounting plate 5 is provided with a mounting groove 6 matching the mounting shape, and the pipe 4 is connected in the mounting groove 6 .

[0030] The mounting plate 5 is specially provided with a notch facing the horizontal direction to avoid hindering the operator from observing the matching of the injection unit and the mold through the feeding area 3. The mounting plate 5 is also provided with a mounting groove 6 matching the shape thereof, which is used to stabilize the pipeline 4 and ensure the stability of its installation.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
