[0001] The utility model belongs to the technical field of plastic molds, and in particular relates to a cooling device for processing plastic molds. Background Art

[0002] A plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection, blow molding and low-foaming molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes. After the processing is completed, the plastic mold needs to be cooled by a cooling device to facilitate the staff to take the injection molded parts.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-5 The utility model provides a cooling device for plastic mold processing, including an operating table 1, a control panel 101 is fixedly installed on the front side of the operating table 1, support columns 2 are fixedly connected to the top of the operating table 1 near the four corners, a mounting plate 3 is fixedly connected to the upper end of the support column 2, an upper mold device 4 is arranged on the upper part of the mounting plate 3, a lower mold cavity 5 is arranged on the operating table 1 corresponding to the upper mold device 4, an ejection mechanism 7 is arranged in the lower mold cavity 5, and a cooling mechanism 6 is installed on the rear side of the operating table 1.

[0024] The cooling mechanism 6 includes a self-circulating water cooler 601, the model of which is DWS (Dio Machinery). The self-circulating water cooler 601 is fixedly installed on the rear surface of the operating table 1. The self-circulating water cooler 601 is fixedly connected with a side wall circulation pipe 602 and a bottom circulation pipe 603. The side wall circulation pipe 602 and the bottom circulation pipe 603 are connected. The side wall circulation pipe 602 is arranged around the lower mold cavity 5 and is arranged in the operating table 1. The bottom circulation pipe 603 is arranged at the bottom of the lower mold cavity 5 and is arranged in the operating table 1.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the control panel 101 is electrically connected to the self-circulating water cooler 601, the side wall circulation pipe 602 is arranged in a spiral shape, and the bottom circulation pipe 603 is arranged in an S shape.

[0026] The self-circulating water cooler 601 is controlled by the control panel 101 to circulate cooling water around and at the bottom of the lower mold cavity 5 through the side wall circulation pipe 602 and the bottom circulation pipe 603, thereby cooling the interior of the lower mold cavity 5 to facilitate molding of plastic products and improve cooling efficiency.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the upper mold device 4 includes a fixed frame 401, which is fixedly installed on the upper part of the mounting plate 3, and an upper mold 404 is slidably arranged in the fixed frame 401 and matched with the lower mold cavity 5. The upper mold 404 is fixedly connected to the left and right sides of the top of the limit blocks 405, and a connecting plate 402 is fixedly connected between the limit blocks 405 at the top of the fixed frame 401. An electric telescopic rod 403 is fixedly installed between the bottom of the connecting plate 402 and the upper mold 404, and the bottom end of the electric telescopic rod 403 is fixedly connected to the upper mold 404.

[0028] According to the above working process, it can be known that the cooling mechanism 6 can quickly cool the interior of the lower mold cavity 5 and improve the cooling efficiency, so as to facilitate the molding of the plastic product inside, thereby improving the processing efficiency of the plastic mold.

[0029] Further as Figure 3 , Figure 4 and Figure 5As shown, it is worth explaining in detail that the ejection mechanism 7 includes a lower template 701, which is slidably arranged at the bottom of the lower mold cavity 5, and a matching block 702 is provided at the bottom of the lower template 701 to match the lower mold cavity 5. The lower template 701 is fixedly connected with four connecting rods 703 near the four corners, and the top of the connecting rod 703 is fixedly connected with a limiting plate 704, and a fixing rod 705 is slidably arranged at the bottom end of the connecting rod 703 and fixedly connected to the lower mold cavity 5. A spring 706 is sleeved on the outer side of the fixing rod 705 and is arranged at the bottom of the connecting rod 703. The connecting rod 703 slides through the operating table 1, and the limiting plate 704 is arranged on the outside of the operating table 1.

[0030] The upper mold 404 is lifted by the electric telescopic rod 403. At the same time, the connecting rod 703 is located at the bottom under the extrusion of the upper mold 404 by the limiting plate 704, and the spring 706 is squeezed. When the upper mold 404 is lifted, the elastic force of the spring 706 causes the connecting rod 703 to slide upward, thereby driving the lower mold plate 701 to slide upward. The setting of the matching block 702 is combined to improve the stability of the sliding process of the lower mold plate 701, and then the molded plastic product is ejected to facilitate the unloading work, thereby improving the processing efficiency.

[0031] This solution has the following working process: when this device is used, the upper mold 404 is pushed into the lower mold cavity 5 by the operation of the electric telescopic rod 403, and injection molding is performed in the lower mold cavity 5 to form the plastic product. At this time, the self-circulating water cooler 601 is controlled by the control panel 101 to circulate the cooling water around and at the bottom of the lower mold cavity 5 through the side wall circulation pipe 602 and the bottom circulation pipe 603, thereby cooling the inside of the lower mold cavity 5 to facilitate the molding of the plastic product and improve the cooling efficiency. When the cooling is completed, the self-circulating water cooler 601 is turned off. At the same time, the upper mold 404 is lifted by the electric telescopic rod 403. At the same time, since the connecting rod 703 is squeezed by the limit plate 704 and is located at the bottom of the upper mold 404, and squeezes the spring 706, when the upper mold 404 is lifted, the elastic force of the spring 706 causes the connecting rod 703 to slide upward, thereby driving the lower mold plate 701 to slide upward. The setting of the matching block 702 is used to improve the stability of the sliding process of the lower mold plate 701, and then the molded plastic product is ejected, so as to facilitate the unloading work, thereby improving the processing efficiency.

[0032] In summary: by setting up the cooling mechanism 6, the temperature around the inside of the lower mold cavity 5 can be quickly cooled, and the cooling efficiency can be improved, so as to facilitate the molding of the plastic products inside it, thereby improving the processing efficiency of the plastic mold; by setting up the ejection mechanism 7, after the plastic product molded in the lower mold cavity 5 is cooled, the upper mold device 4 is lifted to facilitate the ejection of the molded product synchronously in the lower mold cavity 5, so as to facilitate its removal, thereby improving the processing efficiency.
