[0026] Feed port 103 and bottom mould 101 constitute the communication structure, and bottom mould 101 and support leg 104 are integrally arranged, and hydraulic rod 105 is arranged at equal intervals about the inside of bottom mould 101.

[0027] Please refer to Figure 3 In the embodiment, inner layer mould assembly 2 includes cover plate 201, buckle 202, card box 203, sliding block 204, spring 205 and internal mould 206. The side of cover plate 201 is fixedly connected with buckle 202, the outer wall of buckle 202 is clampedly connected with card box 203, the bottom of cover plate 201 is fixedly connected with spring 205, the bottom end of spring 205 is fixedly connected with internal mould 206, and the side of internal mould 206 is provided with sliding block 204.

[0028] The inner mold 206 is elastically connected with the cover plate 201 through the spring 205, and the inner mold 206 is integrally arranged with the sliding block 204.

[0029] Please refer to Figure 4 As shown in the figure, in the embodiment, the cooling assembly 3 comprises a feeding pipe 301, a micro water pump 302, a heat conduction pipe 303 and a water outlet pipe 304.

[0030] The end of the feeding pipe 301 is fixedly connected with the micro water pump 302, the side of the micro water pump 302 is fixedly connected with the heat conduction pipe 303, and the end of the heat conduction pipe 303 is fixedly connected with the water outlet pipe 304; the feeding pipe 301 is in communication with the heat conduction pipe 303 through the micro water pump 302, and the heat conduction pipe 303 is in communication with the water outlet pipe 304.

[0031] The working principle of the present embodiment is as follows: first, the cover plate 201 of the inner mold assembly 2 is moved downward by an external driving device such as a mechanical arm or a transmission mechanism, so that it is close to the top of the outer mold assembly 1. In this process, the buckles 202 on the side of the cover plate 201 gradually engage with the card boxes 203, achieving preliminary positioning and connection. As the cover plate 201 continues to press down, the spring 205 fixedly connected to the bottom of the cover plate 201 begins to be compressed, and the inner mold 206 slowly descends accordingly. Since the inner mold 206 and the sliding block 204 are integrally arranged, the sliding block 204 slides in the corresponding guide rail or groove inside the bottom mold 101, guiding the inner mold 206 to accurately enter the predetermined position inside the bottom mold 101, ensuring that the gap between the inner and outer mold assemblies is uniform and meets the design requirements, and preparing for subsequent injection molding. The raw material is injected into the mold cavity through the feed inlet 103 which is fixedly connected to the side of the bottom mold 101 and forms a communication structure. The position and size of the feed inlet 103 are carefully designed to control the inflow speed and direction of the raw material, so that the raw material first fills the gap between the outer mold assembly 1 and the inner mold assembly 2. During the injection process, the spring 205 plays an important role in the elastic structure formed by the spring 205 and the cover plate 201. The spring 205 can buffer the pressure fluctuations caused by the injection of raw materials, allowing the inner mold 206 to adaptively adjust its position within a certain range, ensuring that the raw material is evenly distributed between the inner and outer mold assemblies, thereby facilitating the formation of an electronic cigarette oil storage product with uniform wall thickness. When the injection of raw materials is completed, the cooling assembly 3 begins to work. The micro water pump 302 is started, causing the cooling liquid to flow into the feed pipe 301, and after being pressurized by the micro water pump 302, the cooling liquid flows into the heat pipe 303. The heat pipe 303 is tightly attached to the inner wall of the outer mold assembly 1 or other critical parts, and transfers heat from the inside of the mold to the cooling liquid through heat conduction. The cooling liquid flows in the heat pipe 303, absorbs heat and flows out from the water outlet pipe 304, forming a complete cooling circulation loop. By adjusting the flow rate and speed of the micro water pump 302, the flow rate and flow of the cooling liquid can be accurately controlled, thereby achieving precise control of the mold temperature and ensuring uniform cooling of the product, reducing product defects caused by uneven cooling. When demolding, the hydraulic rods 105 arranged at equal intervals on the bottom of the bottom mold 101 are simultaneously lifted upward. Due to the uniform distribution and strong pushing force of the hydraulic rods 105, the formed electronic cigarette oil storage product can be smoothly pushed out of the bottom mold 101, completing the demolding process of the outer mold. Then, as the cover plate 201 moves upward, the spring 205 gradually recovers its original length, generating an upward pulling force on the inner mold 206. Under the guidance of the sliding block 204, the inner mold 206 separates from the inner wall of the product along the predetermined path, thus completing the entire demolding process and obtaining a complete electronic cigarette oil storage product.

[0032] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
