Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to a water circulation cooling injection type injection mold device. Background Art

[0002] An injection mold is a tool used to produce plastic products and to give them a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into the mold cavity under high pressure through an injection molding machine, and then cooling and solidifying it to obtain a molded product.

[0003] Although water cooling is also used for cooling injection molds nowadays, most of them are done by drilling holes in the mold to allow water to flow through. This method is not only cumbersome to use, but may also cause water to remain in the mold, thereby reducing the service life of the mold. Drilling holes in the mold may cause the mold core to shift, requiring re-positioning and calibration. In order to solve the above problems, a water circulation cooling injection mold device is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem that although water cooling is also used for cooling injection molds nowadays, most of them are cooled by drilling holes in the mold to allow water to flow through. This method is not only cumbersome to use, but may also cause water to remain in the mold, thereby reducing the service life of the mold. Drilling holes in the mold may cause the mold core to shift, thereby requiring re-positioning and calibration. A water circulation cooling injection mold device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a water circulation cooling injection mold device, comprising a mounting base, a concave mold is fixedly installed on the top surface of the mounting base, a cooling assembly is arranged inside the mounting base, a positioning assembly is arranged on the top of the mounting base, the positioning assembly includes a support frame, and a support frame is fixedly installed on the top surface of the mounting base.

[0006] As a further description of the above technical solution:

[0007] A top plate is fixedly mounted on the top of the support frame, a cylinder is fixedly mounted on the top surface of the top plate, and a cover mold is fixedly mounted on the bottom end of the cylinder.

[0008] As a further description of the above technical solution:

[0009] A positioning rod is fixedly installed on the bottom surface of the cover mold, and the support frame is slidably connected to the cover mold through a sliding groove arranged inside the support frame.

[0010] As a further description of the above technical solution:

[0011] The die is slidably connected to a positioning rod via a through hole provided inside the die, and the die is slidably connected to a limiting frame via a sliding groove provided inside the die.

[0012] As a further description of the above technical solution:

[0013] The cooling assembly includes a heat conducting plate, the bottom of the die is fixedly mounted with the heat conducting plate, and a cooling pipe is fixedly mounted inside the heat conducting plate.

[0014] As a further description of the above technical solution:

[0015] A water tank is fixedly installed at one end of the cooling pipe, a water pump is fixedly installed on one side surface of the water tank, a water pump is fixedly installed at one end of the water pump, and a water pump is fixedly installed at the other end of the cooling pipe.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In the utility model, a positioning component is provided. When the equipment is applied, before the equipment is used, the limit frame is first replaced according to the style of the mold so that the limit frame can adapt to the mold and fix it. Since the mold here is detachable, after the injection molding is cooled, it is only necessary to take out the limit frame and separate the mold to take out the finished product. Then, the cylinder is started to move the cover mold and position it by whether the positioning rod can be inserted. Then, the cover mold is moved up a suitable distance and then moved down, so as to ensure the sealing of the mold during injection molding. After the injection molding is completed, the cylinder is started to cover the top of the mold. Through this design, not only the function of facilitating the fixing of the mold and the removal of the material after injection molding and cooling is realized, but also the function of positioning the mold and the mold core can be achieved. It is simple and convenient to use and has strong practicality.

[0018] 2. In the utility model, a cooling component is provided. During the use of the device, and after the injection molding is completed, the water pump is started to draw cooling water from the water tank through the pumping pipe and transport it to the cooling pipe. Since the heat generated by the injection molding material after injection molding is transmitted to the heat conduction plate, when the cooling water flows through the cooling pipe, the cooling water takes away the heat on the heat conduction plate and finally flows back to the water tank, thereby completing the water recycling and realizing the function of water circulating cooling of the injection molding material in the mold after injection molding. It is simple and convenient to use and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 The utility model provides a technical solution: a water circulation cooling injection mold device, comprising a mounting base 1, a die 2 is fixedly mounted on the top surface of the mounting base 1, a cooling assembly 4 is arranged inside the mounting base 1, a positioning assembly 3 is arranged on the top of the mounting base 1, the positioning assembly 3 includes a support frame 33, and a support frame 33 is fixedly mounted on the top surface of the mounting base 1;

[0027] A top plate 31 is fixedly mounted on the top of the support frame 33, a cylinder 32 is fixedly mounted on the top surface of the top plate 31, a cover mold 34 is fixedly mounted on the bottom end of the cylinder 32, a positioning rod 35 is fixedly mounted on the bottom surface of the cover mold 34, the support frame 33 is slidably connected to the cover mold 34 via a sliding groove provided therein, the die 2 is slidably connected to the positioning rod 35 via a through hole provided therein, and the die 2 is slidably connected to the limiting frame 36 via a sliding groove provided therein;

[0028] The specific implementation method is as follows: when the device is used, before using the device, the limiting frame 36 is replaced according to the style of the mold so that the limiting frame 36 can adapt to the mold and fix it. Since the mold here is detachable, after the injection molding is cooled, it is only necessary to remove the limiting frame 36 and separate the mold to remove the finished product. Then, the cylinder 32 is started to move the cover mold 34 and position it by whether the positioning rod 35 can be inserted. Then, the cover mold 34 is moved upward by a suitable distance and then moved downward to ensure the sealing of the mold during injection molding. After the injection molding is completed, the cylinder 32 is started to make the cover mold 34 cover the top of the mold.

[0029] The cooling assembly 4 includes a heat conducting plate 41, the heat conducting plate 41 is fixedly installed on the bottom of the die 2, a cooling pipe 42 is fixedly installed inside the heat conducting plate 41, a water tank 45 is fixedly installed at one end of the cooling pipe 42, a water pump 44 is fixedly installed on one side of the water tank 45, a water pump 43 is fixedly installed at one end of the water pump 44, and a water pump 43 is fixedly installed at the other end of the cooling pipe 42.

[0030] The specific implementation method is as follows: during the use of the device, and after the injection molding is completed, the water pump 43 is started to pump cooling water from the water tank 45 through the pumping pipe 44 and transport it to the cooling pipe 42. Since the heat generated by the injection molding material after the injection molding is transferred to the heat conducting plate 41, when the cooling water flows through the cooling pipe 42, the cooling water takes away the heat on the heat conducting plate 41 and finally flows back to the water tank 45, thereby completing the water recycling.

[0031] Working principle: Before using the equipment, replace the limit frame 36 according to the style of the mold so that the limit frame 36 can adapt to the mold and fix it. Since the mold here is detachable, after the injection molding and cooling, you only need to remove the limit frame 36 and separate the mold to take out the finished product. Then start the cylinder 32 to move the cover mold 34 and position it by whether the positioning rod 35 can be inserted. Then move the cover mold 34 up a suitable distance and then move it down to ensure the sealing of the mold during injection molding. When the injection molding is completed, start the cylinder 32 to make the cover mold 34 cover the top of the mold, and start the water pump 43 after the injection molding is completed, so that the cooling water is pumped out from the water tank 45 through the pumping pipe 44 and transported to the cooling pipe 42. Since the heat generated by the injection molding material after injection molding is transferred to the heat conducting plate 41, when the cooling water flows through the cooling pipe 42, the cooling water takes away the heat on the heat conducting plate 41, and finally flows back to the water tank 45, thereby completing the water recycling.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
