AI Technical Summary
During the air-cooling and heat dissipation, the existing mold inserts have poor cooling effect in the hot spot area due to the short heat exchange channel.
Design a mold insert circulating air cooling device, the insert is installed on the lower template, and is equipped with a first blind hole and a second blind hole, and a gas spacer is provided in the first blind hole, and the air intake joint and the air outlet joint are respectively located at the partitions. On both sides of the air flap, air exchanges heat through complex paths, increasing the heat exchange distance.
By increasing the heat exchange path of air, the cooling efficiency of the mold insert is significantly improved, especially in hot spot areas.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cooling equipment, and in particular relates to a circulating air cooling device for mold inserts. Background Art
[0002] In the prior art, in order to improve the cooling efficiency of the mold insert, it is usually necessary to form a cooling channel, for example, an air cooling passage, in the injection mold insert. When the mold insert is air-cooled, the heat exchange channel in the insert is short and the heat exchange effect is poor, resulting in poor cooling effect in the hot spot area. Utility Model Content
[0003] The utility model aims to solve the above technical problems at least to a certain extent. To this end, the utility model aims to provide a mold insert circulating air cooling device.
[0004] The technical solution adopted by the utility model is:
[0005] A mold insert circulating air cooling device, the insert is installed on a lower template, a first blind hole is opened at the lower end of the insert, a second blind hole is opened at the top of the first blind hole, a plug is provided at the opening of the first blind hole, an air baffle is provided in the first blind hole to separate the first blind hole to the left and right, the lower end of the air baffle is in sealing contact with the plug, the upper end of the air baffle is located in the middle of the opening of the second blind hole, an air inlet connector and an air outlet connector are provided on the insert, and the air inlet connector and the air outlet connector are respectively located on both sides of the air baffle.
[0006] Preferably, the top of the insert is located in the mold cavity of the mold. The diameter of the second blind hole is smaller than the diameter of the first blind hole. Both the air inlet connector and the air outlet connector are pagoda connectors.
[0007] The beneficial effects of the utility model are:
[0008] The utility model provides a mold insert circulating air cooling device, in which the air entering from the air inlet joint enters the left channel of the first blind hole, then enters the right channel of the first blind hole after passing through the second blind hole, and is finally discharged from the air outlet joint. The stroke is much longer than that of the channel directly radially penetrating the insert, and heat exchange can be performed more effectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the accompanying drawings herein can be arranged and designed in a variety of different configurations.
[0013] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.
[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] like Figure 1 and Figure 2 As shown, a mold insert circulating air cooling device of this embodiment, the insert 1 is installed on the lower template 2, and the insert 1 roughly includes two cylindrical sections, wherein the lower cylindrical section (hereinafter referred to as the large cylindrical section) has a larger diameter, and the upper cylindrical section (hereinafter referred to as the small cylindrical section) has a smaller diameter.
[0016] A first blind hole 3 is opened on the small cylindrical section of the insert 1, a second blind hole 4 is opened on the top of the first blind hole 3, most of the second blind hole 4 is located in the small cylindrical section, the small cylindrical section of the insert 1 is located in the cavity 9 of the mold, and the diameter of the second blind hole 4 is smaller than the diameter of the first blind hole 3.
[0017] A plug 5 for sealing is provided at the opening of the first blind hole 3, and an air baffle 6 is provided inside the first blind hole 3. The air baffle 6 separates the first blind hole 3 into a left channel and a right channel. The lower end of the air baffle 6 is in sealing contact with the plug 5, and the upper end of the air baffle 6 is located at the middle position of the opening of the second blind hole 4, so that the top of the left channel and the top of the right channel are both connected to the second blind hole 4. An air inlet joint 7 and an air outlet joint 8 are provided on the insert 1, and the air inlet joint 7 and the air outlet joint 8 are respectively located on both sides of the air baffle 6. The air inlet joint 7 and the air outlet joint 8 are both pagoda joints, which are convenient for connecting with pipelines.
[0018] The air entering from the air inlet joint 7 enters the left channel, then enters the right channel after passing through the second blind hole 4, and finally is discharged from the air outlet joint 8. Its travel is much longer than the channel that directly radially penetrates the insert 1. Therefore, heat exchange can be more effectively carried out to achieve the purpose of cooling the thick and large positions of the product area, so that the shrinkage holes at the corresponding parts of the product are reduced.
[0019] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
