Description

Technical Field

[0001] This utility model relates to the field of compression molding technology for engine lower guard plates, and specifically to a compression molding device for engine lower guard plates. Background Technology

[0002] An engine underbody shield is a plate installed inside the car body to protect the engine. It is usually installed at the bottom of the engine, hence the name engine underbody shield. Engine underbody shields are often made of composite materials such as PP, and are manufactured into the required size and shape using injection molding and hot pressing processes. However, residual material in the mold cavity during the mold closing and opening process cannot be cleaned in time, which affects the next mold closing and also affects the production efficiency of the entire production line.

[0003] The existing engine underbody protection plate molds cannot clean the residue inside the mold cavity after molding and opening. For example, a high-efficiency hot pressing mold disclosed in CN218803534U has electric heating block assemblies in both the upper and lower mold head cavities. The electric heating block assemblies are used to keep the mold head at a high temperature. The electric heating block assembly includes symmetrically arranged heating blocks, which are the main heat-conducting components in the electric heating block assembly. Heating fins are arranged between the symmetrical heating blocks in the vertical direction. When energized, the heating fins convert electrical energy into heat energy and conduct it to the heating blocks. The heating block continuously dissipates heat within the mold cavity, causing the mold itself to heat up. A heat dissipation groove is provided on the upper heating block, with the upper end of the heating fins extending through it. This heat dissipation groove further increases the heat transfer efficiency between the heating fins and the heating block. The electric heating block assembly in this mold conducts and dissipates the heat emitted by the heating fins through the heating block. Under the same energy consumption, it can efficiently conduct heat, resulting in high overall thermal efficiency for the mold. However, if material residue within the mold cavity cannot be resolved, or the mold cannot be cleaned, it will affect the mold's subsequent or repeated use.

[0004] Therefore, it is necessary to invent a molding device for engine underbody protection plates to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a molding device for engine lower guard plates, so as to solve the problem that residual material in the mold cavity cannot be cleaned during the molding operation of engine lower guard plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A molding device for an engine underbody shield includes a molding device body, a material storage box, a feeding port, an upper template, and a lower template. The molding device body is provided with a material storage box, which is connected to the feeding port via a pipe. The feeding port is located on the side of the upper template. The upper template is connected to and driven by a cylinder. The lower template is driven by a cylinder. The lower template and the upper template can fit together completely. A fixing frame is fixedly connected to the molding device body. An electric fan and a cylinder are installed on the fixing frame. A high-pressure nozzle is connected to the cylinder via a push rod.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] 1. This utility model uses a fixed mounting bracket that extends from the side of the main body of the device to install an electric fan, which dissipates the large amount of steam generated during mold opening. Dissipating the steam makes it easier for operators to pick up parts, thereby improving the overall manufacturing and part retrieval efficiency.

[0010] 2. This utility model uses a cylinder three installed on a fixed frame to push the push rod back and forth. Under the action of the sleeve, the high-pressure nozzle moves back and forth. Each back and forth movement can clean the residual material in the inner cavity of the upper and lower molds after the mold is opened, which facilitates the reuse of the upper and lower mold plates and extends their service life.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figures 1-3 The device shown is a molding apparatus for an engine underbody plate, comprising a molding apparatus body 1, a material storage box 2, a feeding port 3, an upper template 4, and a lower template 6. The material storage box 2 is provided on the molding apparatus body 1, and the material storage box 2 is connected to the feeding port 3 through a pipe. The feeding port 3 is opened on the side of the upper template 4. The upper template 4 is connected to and driven by a cylinder 5. The lower template 6 is driven by a cylinder 7. The lower template 6 and the upper template 4 can fit together completely. A fixing frame 8 is fixedly connected to the molding apparatus body 1. A fan 9 and a cylinder 10 are installed on the fixing frame 8. A high-pressure nozzle 13 is connected to the cylinder 10 through a push rod 11.

[0019] The upper mold 4 and the lower mold 6 are brought close together to form the internally filled raw material by hot pressing, thus creating the lower guard plate workpiece. The electric fan 9 is used to dissipate the large amount of steam when the mold is opened, making it easier for the operator to remove the part.

[0020] A sleeve 12 is fitted onto the high-pressure nozzle 13. One end of the high-pressure nozzle 13 is connected to a high-pressure air source connecting pipe 14, which is connected to an external air source. The high-pressure nozzle 13 is arranged in an inclined L-shape, and the length of the high-pressure nozzle 13 is adapted to the inner dimensions of the upper template 4 and the lower template 6. The length of the high-pressure nozzle 13 is less than the distance between the two guide rails on the same side, and the range in which the high-pressure nozzle 13 is pushed by the push rod 11 is adapted to the maximum dimensions of the upper template 4 and the lower template 6.

[0021] By using the high-pressure nozzle 13 to move laterally back and forth at the closing and opening heights of the upper mold plate 4 and the lower mold plate 6, the material residue inside the upper mold plate 4 and the lower mold plate 6 after the mold is opened is cleaned, making it easy for the upper mold plate 4 and the lower mold plate 6 to be reused.

[0022] The fixing frame 8 extends out of the main body 1 of the molding device, and the height of the fan 9 is flush with the closing height of the upper template 4 and the lower template 6. The closing and opening of the upper template 4 and the lower template 6 are both moved up and down by four guide rails. The four guide rails are fixedly connected inside the main body 1 of the molding device. The relative movement of the upper template 4 and the lower template 6 is synchronous, and their relative distance is also synchronous.

[0023] The electric fan 9 and cylinder 3 10 are both positioned outside the main body 1 of the molding device, and the length of the high-pressure nozzle 13 is less than that between the two guide rails on the same side. This does not affect the ejection and resetting of the high-pressure nozzle 13, ensuring the complete operating path of the high-pressure nozzle 13, and also enabling a complete cleaning of the inner surfaces of the upper template 4 and the lower template 6.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual appendix Figure 1-3 When using this utility model, first fill the material storage box 2 with semi-fluid molding material (a mixture of PP raw materials and other composite materials), and connect it to the feed port 3 through a hose or elastic hose and seal it. Then, the cylinder 1 5 and cylinder 2 7 can be started to start the injection molding and molding operation.

[0026] Refer to the instruction manual appendix Figure 3-5 When using this utility model, as the upper template 4 and the lower template 6 move closer and closer until they are completely sealed, the raw material filled inside is pressed into the shape of the lower protective plate.

[0027] After pressing is completed, the upper mold 4 and the lower mold 6 need to be separated and kept relatively far apart. During the mold opening process, a large amount of steam will be generated due to high temperature hot pressing and internal condensation, which will affect the removal of parts. Therefore, the electric fan 9 needs to be used to disperse the steam to facilitate the removal of parts. After the parts are removed, there will be material residue between the upper mold 4 and the lower mold 6, which will not be convenient for the next molding operation. Therefore, the inside needs to be cleaned.

[0028] The cylinder 10 needs to be activated to push the push rod 11 to push the high-pressure nozzle 13 to the outermost part of the upper template 4 and the lower template 6 (the limit length of the push rod 11). One back-and-forth movement will clean the residue inside the upper template 4 and the lower template 6 by using the high-pressure jet operation, so that the upper template 4 and the lower template 6 can be reused.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
