Description

Technical Field

[0001] The utility model relates to the technical field of mold processing equipment, in particular to a cooling device for metal mold processing. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry".

[0003] In order to obtain higher hardness, metal molds are often treated by quenching. However, the existing quenching equipment generally adopts an immersion cooling method during the cooling process, which causes a large amount of cooling water to be vaporized and pollutes the coolant during the cooling process. Therefore, it needs to be replaced regularly, which increases the cost. In addition, in order to avoid mutual influence of molds when cooling in the same pool, the existing cooling equipment generally cools them separately one by one, which is time-consuming. Utility Model Content

[0004] Based on the above description, the utility model provides a cooling device for metal mold processing to solve the shortcomings of existing mold quenching cooling equipment in actual use, such as high coolant consumption cost and the need for separate cooling in sequence, resulting in relatively low cooling efficiency.

[0005] The utility model is realized through the following technical solutions:

[0006] A cooling device for metal mold processing comprises a box body, wherein a feed port and a discharge port are respectively arranged on both sides of the box body, and a cooling chamber is also arranged inside the box body, conveyor belts are arranged on both sides of the cooling chamber and extend to the outside of the box body along the feed port or the discharge port, and a lifting frame is also movably installed in the cooling chamber, and a storage platform is arranged on the lifting frame, and the storage platform is arranged in the middle of two groups of conveyor belts, and a spray assembly is also arranged on the inner wall of the cooling chamber, and the water inlet end of the spray assembly passes through the box body and is connected to a water tank.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, there are two cooling chambers arranged with an interval up and down, each cooling chamber is a rectangular space composed of a plurality of partitions connected to the interior of the box, and the spray assembly is arranged on the partition and toward the center of the cooling chamber.

[0009] Furthermore, through holes are arranged at the centers of opposite sides of the two cooling chambers, and the through holes are rectangular square holes. The lifting frame is a rectangular frame, and the top and bottom surfaces are just adapted to the size of the through holes.

[0010] Furthermore, the side walls of the through hole extend outward to the inner wall of the box body and form a slide groove, and plug plates are correspondingly arranged on both sides of the lifting frame and plugged into the slide groove.

[0011] Furthermore, a screw rod is arranged inside the slide groove, and the screw rod vertically penetrates the plug plate downward and has two ends rotatably connected to the inner wall of the slide groove respectively. The screw rod is threadedly assembled with the plug plate, and a servo motor is also provided on the top of the box body. The output end of the servo motor is arranged vertically downward and is transmission-connected to one end of the screw rod.

[0012] Furthermore, two storage platforms are provided, and mounting grooves are arranged at the center of the top surface and the inner bottom surface of the lifting frame. A hinge seat and an electric telescopic rod are arranged at both ends of the mounting groove, respectively. The storage platform is in the shape of a rectangular square plate and one end is movably connected to the hinge seat. The other end of the storage platform is placed on the top of the electric telescopic rod and the entire surface of the storage platform is arranged flush with the surface of the lifting frame.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] 1. In this application, spray cooling is used to replace the existing immersion cooling, which not only saves a lot of coolant, but also has a very small particle size after atomization. Therefore, the water droplets will evaporate quickly after contacting the mold surface, thereby absorbing a large amount of heat and discharging it. Compared with the existing immersion cooling equipment, the coolant can be used more efficiently, and there is no need to filter the cooling water due to repeated quenching;

[0017] 2. In the present application, two separate cooling chambers are used for alternating quenching, that is, when the upper cooling chamber is quenching, the lower cooling chamber takes out the quenched workpiece. This continuous alternating operation mode enables the device to work continuously and uninterruptedly, greatly improving the efficiency of mold processing and production.

Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] Combination Figure 1-4 As shown, a cooling device for metal mold processing includes:

[0026] The box body 1 is the main part of the whole device, and a feed port and a discharge port are arranged on both sides respectively. A conveyor belt 2 for transferring mold steel is also arranged at the feed port and the discharge port;

[0027] The cooling chamber 3 is arranged inside the box 1 and is mainly used to quickly cool the heated mold steel to achieve a quenching effect;

[0028] The spray assembly 4 is arranged inside the cooling chamber 3 and atomizes the coolant by spraying, so as to use the coolant more efficiently without the need to filter or replace the coolant repeatedly.

[0029] Specifically, there are two cooling chambers 3 arranged with an interval up and down, and the two cooling chambers 3 are rectangular spaces formed by the partition and the inner wall of the box body 1, and a through hole 31 is also arranged at the center of the opposite sides of the two cooling chambers 3. The through hole 31 extends outward to the inner wall of the box body 1 and forms a slide groove. A lifting frame 5 is arranged inside the slide groove, and plug plates 51 are arranged on both sides of the lifting frame 5. The plug plates 51 are slidably inserted into the slide groove, so that the entire lifting frame 5 can move in the vertical direction.

[0030] Based on the above lifting and lowering adjustment structure, a screw rod 11 should also be vertically arranged inside the slide groove. The screw rod 11 is movably assembled with the plug plate 51 through a threaded structure, and both ends are rotatably connected to the inner top surface and the inner bottom surface of the slide groove respectively. In addition, a servo motor 12 should be provided on the top surface of the box body 1. The output shaft of the servo motor 12 is arranged vertically downward and is transmission-connected to one end of the screw rod 11, thereby controlling the lifting distance of the lifting frame 5.

[0031] The main body of the lifting frame 5 is a rectangular frame structure composed of four rectangular plates and four pillars, so the two side surfaces are opened and respectively close to the two groups of conveyor belts 2, so that the conveyor belts 2 can be used for loading and unloading processing to realize automatic operation.

[0032] In order to further improve the processing efficiency of mold quenching, in this embodiment, a storage platform 52 is respectively arranged at the center of the two horizontally arranged rectangular plates on the upper and lower parts of the lifting frame 5, so as to cooperate with the two cooling chambers 3 arranged at intervals from top to bottom to perform continuous quenching work, that is, the rectangular plates arranged horizontally on the lifting frame 5 are adapted to the size of the through holes 31 of the cooling chambers 3, and the height of the lifting frame 5 is set to be the same height as the cooling chamber 3, so when the surface of the rectangular plate on the top of the lifting frame 5 is flush with the bottom surface of the cooling chamber 3 above, the surface of the rectangular plate at the bottom of the lifting frame 5 is just flush with the top surface of the cooling chamber 3 below. When the lifting frame 5 is fully retracted to the cooling chamber 3 below, its top surface of the lifting frame 5 is flush with the top surface of the cooling chamber 3 below. Figure 2 and Figure 3 As shown, the lifting frame 5 can cooperate with the conveyor belt 2 to continuously transport the upper and lower cooling chambers 3 during the reciprocating movement, that is, when the upper cooling chamber 3 is loaded with materials, the lower cooling chamber 3 is also unloaded with materials at the same time, which greatly saves the time spent on changing materials, and the whole operation process is very streamlined, simple in structure, and very convenient to use.

[0033] In the actual production process, the mold is a metal part and therefore has a certain weight. In order to facilitate stable material discharge after quenching, an installation groove 53 should be arranged at the center of the two horizontally arranged rectangular blocks above and below the lifting platform. An electric telescopic rod 54 is embedded in the end of the installation groove 53 facing the feed port, and a hinge seat 55 is arranged at the end of the installation groove 53 facing the discharge port. The two ends of the storage platform 52 are respectively movably connected to the hinge seat 55 and the electric telescopic rod 54, so that the surface of the storage platform 52 is arranged flush with the surface of the lifting platform, and the lifting platform can rely on the electric telescopic rod 54 to lift it into an inclined surface, and the mold will smoothly slide onto the conveyor belt 2 along its inclined surface and be discharged along the discharge port.

[0034] During the conveying process, in order to prevent the mold from deviating when being conveyed to the storage table 52 on the lifting frame 5, the heated mold needs to be guided to the center to avoid collision with the pillars on the lifting frame 5. Therefore, it is necessary to arrange guide blocks 21 on both sides of the conveyor belt 2 arranged near one end of the feed port in advance. The opposite sides of the two guide blocks 21 are inclined and extend toward the center of the conveyor belt 2, and finally form a V-shaped guide groove above the conveyor belt 2. When the mold is transported by the conveyor belt 2, it automatically moves along its inclined surface to the center of the conveyor belt 2.

[0035] The spray assembly 4 is composed of a plurality of atomizing nozzles 41 fixedly mounted on the inner wall of the cooling chamber 3 and a water pipe. The plurality of atomizing nozzles 41 are interconnected by means of the water pipe, and a water pump is provided on the water pipe. The water pump passes through the water pipe to the outside of the box body 1 and is connected to an external water source. In addition, for the consideration of water mist refinement, the atomizing nozzle 41 of this embodiment can also be set as a two-fluid atomizing nozzle to improve the atomization efficiency and enhance the cooling effect.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
