[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 4 shown, the present utility model provides a technical solution: a die-casting mold for the retractable slider of the intake valve, including a die-casting mold assembly 1 for the retractable slider of the intake valve. A preheating assembly 3 is arranged inside the die-casting mold assembly 1 for the retractable slider of the intake valve. A mounting assembly 2 is arranged on the side of the die-casting mold assembly 1 for the retractable slider of the intake valve. The die-casting mold assembly 1 for the retractable slider of the intake valve includes an upper mold 101 and a lower mold 102. The mounting assembly 2 includes a mounting piece 201. A connecting block 107 is installed inside the mounting piece 201. A fixed plate 202 is installed at the bottom of the mounting piece 201. Tension springs 203 are symmetrically installed at the top of the fixed plate 202. A limiting piece 204 is connected to the top of the tension spring 203. A limiting block 205 is installed inside the inner side of the limiting piece 204. A clamping groove is formed at the top of the connecting block 107. The limiting block 205 is installed inside the clamping groove. A limiting rod 206 penetrates through the inside of the mounting piece 201. A limiting groove 207 is formed inside one end of the limiting rod 206. A fixed rod 208 is installed inside the limiting groove 207. One end of the limiting groove 207 penetrates through the inside of the connecting block 107, the limiting piece 204, and the limiting block 205. A threaded rod 106 penetrates through the inside of the connecting block 107. A lifting motor 105 is installed at the bottom of the threaded rod 106.

[0024] In this embodiment, the lifting motor 105 is used to electrically drive the threaded rod 106 to rotate, so that the connecting block 107 drives the upper mold 101 to lift, which is beneficial to die-casting the retracted slider of the intake valve. The guide rod 104 is beneficial to improve the guiding effect and ensure the stability of the lifting of the upper mold 101. When maintenance and repair of the upper mold 101 are required, the upper mold 101 is driven by the lifting motor 105 to disengage from the inside of the guide rod 104, and then the fixing rod 208 is taken out from the inside of the limit groove 207. Subsequently, the limit rod 206 is pulled out to move the limit member 204 upward, so that the limit block 205 disengages from the clamping groove at the top of the connecting block 107. Finally, the mounting member 201 is moved downward, which facilitates the disassembly of the upper mold 101. The operation is fast and the steps are simple, which is convenient for maintaining and repairing the upper mold 101 at any time, shortening the installation and disassembly time, and thus improving the work efficiency. When installation is required, the mounting member 201 is clamped on the outside of the connecting block 107. Using the elastic tension of the tension spring 203, the limit member 204 is driven to descend to cause the limit block 205 to limit the connecting block 107. Finally, the limit rod 206 is used to limit the mounting member 201. The fixing rod 208 is beneficial to limit the limit rod 206.

[0025] Embodiment 2: As Figures 1 - 4 shown, the preheating assembly 3 includes a heater 301. Heating wires 302 are installed at both ends of the heater 301. An installation groove 303 is formed inside the lower mold 102. One end of the heating wire 302 penetrates through the installation groove 303. Guide grooves 109 are formed at the four corners inside the upper mold 101. Guide rods 104 are installed inside the guide grooves 109. A feed port 103 is installed at the top of the upper mold 101. One end of the guide rod 104 is connected to the top of the lower mold 102. A sealing ring 108 is installed at the top of the lower mold 102.

[0026] In this embodiment, it is convenient to add molten metal into the upper mold 101 through the feed port 103. The sealing ring 108 is beneficial to provide a sealing effect for the overlap of the upper mold 101 and the lower mold 102. Before die-casting the retracted slider of the intake valve, heating is carried out through the heater 301, so that the heating wires 302 uniformly release heat, which is beneficial to heating the lower mold 102, facilitating preheating the lower mold 102 in advance, reducing the temperature difference with the high-temperature molten metal, reducing the occurrence of cracks, deformation, etc. in the lower mold 102 due to thermal shock, extending the service life of the lower mold 102, reducing the maintenance cost, and at the same time facilitating the uniform filling of the molten metal inside the lower mold 102, reducing the probability of producing defective products.

[0027] Working principle of this embodiment: During use, first, the heater 301 heats up, and then the heating wire 302 evenly releases heat, which is beneficial to heating the lower mold 102 and facilitating preheating the lower mold 102 in advance. Subsequently, the lifting motor 105 electrically drives the threaded rod 106 to rotate, causing the connecting block 107 to drive the upper mold 101 to descend, so that the upper mold 101 overlaps with the lower mold 102. Then, the molten metal is conveniently added into the upper mold 101 through the feed port 103. The sealing ring 108 is beneficial to providing a sealing effect for the overlap of the upper mold 101 and the lower mold 102, and die-casting the in-contraction slider of the air inlet valve. When maintenance and repair of the upper mold 101 are required, the lifting motor 105 drives the upper mold 101 to disengage from the inside of the guide rod 104, then the fixing rod 208 is taken out from the inside of the limit groove 207. Subsequently, the limit rod 206 is pulled out and the limiting member 204 is moved upward, so that the limiting block 205 disengages from the clamping groove at the top of the connecting block 107. Finally, the mounting member 201 is moved out downward, which facilitates the disassembly of the upper mold 101. The operation is fast and the steps are simple, which is convenient for maintaining and repairing the upper mold 101 at any time.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
