Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing equipment, in particular to a foam sleeve mold rapid manufacturing device. Background Art

[0002] A foam sleeve mold is a mold made of foam material, mainly used in casting, shaping, and forming processes. This mold is light, easy to process, and low in cost, so it has been widely used in industrial production. The material used to make the foam sleeve mold is usually lightweight foam materials such as polystyrene foam (EPS) or polyurethane foam (PU). These materials have good plasticity and stability and can be cut, carved, bonded, and processed into molds of various shapes as needed. At the same time, the foam mold also has good thermal insulation and heat preservation properties, which can effectively reduce energy consumption and production costs.

[0003] Among them, numerical control (CNC) engraving machines can accurately engrave and process foam materials to create complex molds or products. This equipment is usually equipped with computer-aided design (CAD) software, which can quickly convert design drawings into processing instructions. However, since foam materials are relatively light, they are easily offset when placed directly on the processing table of the CNC engraving machine, thus affecting the engraving accuracy. In addition, if the debris is not cleaned up in time during the engraving process, it will also affect the engraving processing operation.

[0004] In view of the above problems, the utility model document proposes a foam sleeve mold rapid manufacturing device. Utility Model Content

[0005] The utility model provides a foam sleeve mold rapid manufacturing device, which solves the shortcomings of the prior art that the foam material is relatively light and is directly placed on the processing table of a CNC engraving machine, which is prone to deviation, thereby affecting the engraving accuracy, and that during the engraving process, debris is not cleaned up in time, which also affects the engraving processing operation.

[0006] The utility model provides the following technical solutions:

[0007] A foam sleeve mold rapid manufacturing device, comprising:

[0008] A CNC engraving machine body, on which an engraving table for placing an original workpiece to be processed and an engraving tool head for engraving the original workpiece are installed;

[0021] Engraving process: Start the CNC engraving machine body, and the engraving head starts working according to the preset engraving program. During the engraving process, the engraving head engraves according to the set path and depth under the control of the CNC engraving machine body. At the same time, a small booster water pump starts working, drawing water from an external water source and transporting it to the inside of the water pump through a pumping pipe. The pressurized water enters the annular water supply pipe through a delivery hose and is sprayed out from multiple high-pressure nozzles.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0035] Embodiment 1:

[0036] Please refer to Figure 1-4 , a foam sleeve mold rapid manufacturing equipment, aimed at improving the manufacturing efficiency and processing accuracy of the foam sleeve mold, the equipment is mainly composed of a CNC engraving machine body 1, a fixing component and a cooling and chip cleaning component:

[0037] The CNC engraving machine body 1 is the main part of the equipment, the model is 60130CNC, and an engraving table 2 and an engraving tool head 3 are installed on it. The engraving table 2 is used to place the foam original to be processed, and the engraving tool head 3 is used to engrave the foam original according to a preset program;

[0038] The fixing assembly is used to clamp and fix the original to be processed to ensure that it will not deviate during the engraving process, thereby improving the processing accuracy. The fixing assembly includes two rotating plates 4 symmetrically installed on the top of the engraving table 2. A cylinder 5 is fixedly installed at the center of the inner wall of each rotating plate 4. The output end of the cylinder 5 is connected to the clamping plate 6. When it is necessary to fix the foam original to be processed on the engraving table 2, it is only necessary to place the foam original between the two clamping plates 6, and then start the cylinder 5 to move the two clamping plates 6 toward each other until the foam original is firmly clamped;

[0039] In order to ensure the stability of the clamping plate 6 during the movement, two guide rods 7 are symmetrically arranged between the two rotating plates 4. The two ends of the clamping plate 6 are slidably mounted on the corresponding guide rods 7. In this way, when the cylinder 5 drives the clamping plate 6 to move, the guide rods 7 can provide a stable guiding effect for the clamping plate 6 to prevent it from shaking or deflecting.

[0040] The cooling and chip cleaning component is mainly used to wash away the debris generated during the engraving process and reduce the temperature of the engraving tool head 3. The cooling and chip cleaning component includes a hollow cylinder 8 installed on the outer wall of the engraving tool head 3. An annular water supply pipe 9 is fixedly arranged at the bottom of the hollow cylinder 8. The bottom of the annular water supply pipe 9 is connected to a plurality of high-pressure nozzles 10 in an annular array. When the engraving tool head 3 is engraving, the high-pressure nozzle 10 will spray high-pressure water flow, which can not only wash away the debris generated during the engraving process, but also cool the engraving tool head 3 to prevent it from overheating.

[0041] In order to provide a stable water source with a certain pressure, a small booster water pump 11 is fixedly installed on the outer wall of the mounting frame of the engraving head 3. The input end of the small booster water pump 11 is connected to the external water source through a pumping pipe 13, and the output end is connected to the input end of the annular water supply pipe 9 through a delivery hose 12. In this way, the small booster water pump 11 can extract water from the external water source, and after pressurization, it is delivered to the annular water supply pipe 9, and then sprayed out by the high-pressure nozzle 10.

[0042] Embodiment 2:

[0043] Improvements based on Example 1:

[0044] Please refer to Figure 3-4 In order to improve the chip flushing and cooling effects, multiple high-pressure nozzles 10 are tilted and converged toward the engraving head 3. In this way, when the high-pressure water flow is ejected from the high-pressure nozzle 10, a water flow beam converging toward the engraving head 3 can be formed, thereby more effectively flushing away the debris and reducing the temperature of the engraving head 3.

[0045] Please refer to Figure 4 The inner wall of the hollow cylinder 8 is provided with an internal thread, and the outer wall of the engraving tool head 3 is provided with an external thread matching the internal thread, so that the inner wall of the hollow cylinder 8 and the outer wall of the engraving tool head 3 are threadedly connected to each other for replacement and maintenance.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the CNC engraving machine body 1, the cylinder 5 and the small booster water pump 11 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0047] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
