For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0059] Example:

[0060] like Figures 1-8 As shown in the figure, this application discloses a mixing tank injection mold for injection molding a mixing tank. Its specific structure includes: a top plate 1, an upper mold sleeve 2, an upper mold core 3, a lower mold sleeve 4, a molding column 5, a release mold 6, two side plates 7, a bottom plate 8, and a lifting mechanism 9.

[0061] The top surface of the top plate 1 is provided with an injection flow channel 101 for guiding molten plastic into the mold. The top plate 1 is preferably composed of two plates, upper and lower, which facilitates production, manufacturing and maintenance.

[0062] The upper mold sleeve 2 is located on the lower side of the top plate 1 and fits tightly with the top plate 1. A medium cavity 201 is opened on the bottom surface to form the barrel body of the mixing tank.

[0063] The upper mold core 3 is embedded on the top surface of the upper mold sleeve 2, and the bottom surface has an upper cavity 301 for forming the bottom part of the mixing tank. The upper cavity 301 is connected to the injection flow channel 101 to ensure that the injection material can flow in smoothly.

[0064] The lower mold sleeve 4 is located below the upper mold sleeve 2 and is used to provide support and positioning.

[0065] The forming column 5 is located on the top surface of the lower mold sleeve 4 and extends upward into the middle cavity 201 and the upper cavity 301 to shape the internal cavity of the mixing tank.

[0066] The template 6 is fitted outside the forming column 5 and arranged between the upper mold sleeve 2 and the lower mold sleeve 4, and the top surface has a lower cavity 601 for forming the top part of the mixing tank.

[0067] Two side plates 7 are installed on both sides of the bottom surface of the lower mold sleeve 4, which serve to support and fix the mold structure, and also serve as the installation base for the lifting mechanism 9.

[0068] The base plate 8 is installed on the bottom surface of the two side plates 7, providing a stable base for the entire mold.

[0069] The lifting mechanism 9 is arranged between the two side plates 7 and is in transmission connection with the stripping plate 6, and is used for driving the stripping plate 6 to move up and down during stripping, so as to assist the stirring barrel to be smoothly and safely stripped out of the mold.

[0070] When the mold is closed, the upper cavity 301, the middle cavity 201 and the lower cavity 601 are sequentially spliced and cooperated with the forming column 5 to jointly form a forming space.

[0071] The above technical scheme has the following working mode:

[0072] When the mold is closed, the upper mold sleeve 2, the stripping plate 6 and the lower mold sleeve 4 are kept in close contact with each other, so that the middle cavity 201 and the lower cavity 601 are spliced, and the forming column 5 extends into the middle cavity 201 and the upper cavity 301, so that the forming space is jointly formed; then, the molten injection material enters the upper cavity 301 through the injection runner 101, and then fills the entire forming space, thereby completing the injection molding of the stirring barrel.

[0073] When the mold is opened, the top plate 1, the upper mold sleeve 2 and the upper mold core 3 remain stationary, the bottom plate 8 drives the side plate 7, the lower mold sleeve 4, the stripping plate 6 and the forming column 5 to move away from the top plate 1, so that the upper mold sleeve 2 and the stripping plate 6 are gradually separated, and the forming column 5 withdraws from the middle cavity 201 and the upper cavity 301 with the formed stirring barrel.

[0074] When the mold is stripped, the lifting mechanism 9 drives the stripping plate 6 to move away from the bottom plate 8, so that the stripping plate 6 exerts a force on the stirring barrel through the lower cavity 601, so that the inner surface of the stirring barrel is separated from the forming column 5; then, the operator can easily take out the stirring barrel from the lower cavity 601.

[0075] It should be noted that, as shown in Figure 6 The reinforcing ring arranged at the outer periphery of the opening of the stirring barrel is formed in the spliced region of the middle cavity 201 and the lower cavity 601, so that the situation of being unable to strip is avoided, and the structural strength of the region is increased, so that deformation or damage does not occur when the lower cavity 601 exerts a force, thereby improving the product quality.

[0076] The utility model discloses a stripping plate 6 is set up, and the lower cavity 601 is set up on the top surface of stripping plate 6, so that the contact area with the stirring barrel is significantly enlarged, thereby reducing stress concentration and improving support stability, so that the stirring barrel can be easily and conveniently pushed under the premise of ensuring that the stirring barrel is not damaged, and the inner surface of the stirring barrel is separated from the forming column 5, which improves the stripping smoothness and improves the stripping efficiency.

[0077] In some embodiments, as shown in Figure 7 and Figure 8As shown, the lifting mechanism 9 comprises a plurality of guide rods 901, a push plate 902 and a plurality of drive rods 903, which are arranged as follows:

[0078] The plurality of guide rods 901 are arranged between the lower die sleeve 4 and the bottom plate 8, which play a guiding and supporting role, ensuring that the push plate 902 moves smoothly and without deviation along the predetermined direction;

[0079] The push plate 902 is slidably sleeved on the guide rod 901, which is used to transmit driving force to the drive rod 903, so as to lift or lower the stripper plate 6, and the push plate 902 is preferably composed of two plates, so as to facilitate the assembly and fixation of each component and subsequent maintenance;

[0080] The plurality of drive rods 903 are arranged on the top surface of the push plate 902 and pass through the lower die sleeve 4 upwards, and are fixedly connected with the stripper plate 6, which play a role of transmitting driving force and displacement, and are used to drive the stripper plate 6 to lift or lower;

[0081] Among them, the bottom surface of the bottom plate 8 is provided with a plurality of drive through holes 801, which allow the piston rod of the driving mechanism to pass through the bottom plate 8, so as to be connected with the push plate 902, so that when the driving mechanism works, the extension and retraction of the piston rod will drive the push plate 902 to slide on the guide rod 901, thereby realizing the lifting and lowering of the stripper plate 6.

[0082] Through the above design of the lifting mechanism 9, the precise lifting and lowering control of the stripper plate 6 is realized by the cooperation between each component and the cooperation of the drive through holes 801 on the bottom plate 8, which has the advantages of simple and compact structure, smooth operation and stability of the mold stripping.

[0083] In some embodiments, as shown in Figure 4 , Figure 5 and Figure 10 , the top surface of the forming column 5 is provided with a hole forming groove 501, and the top surface of the bottom plate 8 is provided with a hole forming rod 10, which passes through the lower die sleeve 4 upwards and is inserted into the hole forming groove 501.

[0084] During the injection molding process, the injection molding material will flow into the space formed by the hole forming groove 501 and the side wall of the hole forming rod 10. When the injection molding material cools and solidifies, the mold performs the opening action, and the lifting mechanism 9 drives the stripper plate 6 to move upwards, thereby ejecting the molded part from the mold; at this time, the bottom of the stirring barrel will form a jack.

[0085] Through the cooperation of the hole forming groove 501 and the hole forming rod 10, the key components for forming a specific shaped hole in the mold are formed, which improves the flexibility and adaptability of the mold and also ensures the use effect of the molded part.

[0086] On the basis of the above embodiments, as shown in Figure 4 and Figure 5As shown, the lifting mechanism 9 comprises a lifting pipe 904 mounted on the push plate 902 and sleeved on the hole forming rod 10, and the top end is flush with the bottom of the hole forming groove 501.

[0087] When the mold is closed, the top end of the lifting pipe 904 is flush with the bottom of the hole forming groove 501, thereby closely cooperating with the stripping plate 6 and the forming column 5 to form a complete hole forming space.

[0088] When the mold is stripped, the push plate 902 will drive the lifting pipe 904 to slide along the hole forming rod 10, thereby exerting a force on the jack to facilitate the jack to be stripped from the hole forming groove 501.

[0089] By providing the lifting pipe 904, the jack can be subjected to a force during stripping to facilitate stripping of the jack, thereby improving the opening and stripping efficiency of the mold and ensuring high precision and high quality of the molded part.

[0090] In some embodiments, as shown in Figure 4 and Figure 7 The bottom surface of the upper die sleeve 2 has a convex ring 202 coaxially arranged with the middle cavity 201, and the top surface of the stripping plate 6 is provided with a ring groove 602 matched with the convex ring 202.

[0091] During the closing of the mold, the convex ring 202 of the upper die sleeve 2 is accurately inserted into the ring groove 602 of the stripping plate 6 and closely fitted.

[0092] Through the above arrangement, the middle cavity 201 and the lower cavity 601 can be accurately matched, thereby ensuring the consistency and stability of the molding space and improving the quality and precision of the molded part.

[0093] In some embodiments, as shown in Figure 4 The inside of the upper die sleeve 2 is provided with a plurality of outer cooling channels 203 arranged around the middle cavity 201, which are preferably uniformly distributed to ensure the consistency and uniformity of the cooling effect; the outer cooling channel 203 is in a U-shaped structure, and the inlet and outlet are arranged on the side surface of the upper die sleeve 2, which helps to make the flow path of the cooling liquid close to the middle cavity 201, thereby improving the cooling efficiency, and facilitating the connection with the pipeline of the cooling system, so that the cooling medium can enter and exit the outer cooling channel 203 through the inlet and outlet, realizing the cooling effect of the mold.

[0094] Through the above arrangement, the heat inside the middle cavity 201 can be absorbed and taken away by the circulating cooling liquid, thereby externally promoting the cooling and solidification speed of the stirring barrel, thereby improving the production efficiency.

[0095] In some embodiments, as shown in Figure 4As shown, the forming column 5 is internally provided with a plurality of circumferentially spaced internal cooling channels 502, which are in U-shaped structure, thereby having a curved shape, which can adapt to the layout and size limitation inside the forming column 5, and increase the flow path and contact area of the cooling liquid, improve the cooling efficiency, and the inlet and outlet are arranged at the bottom surface of the forming column 5, so that the cooling liquid can conveniently enter and exit the internal cooling channel 502, realize effective cooling of the forming column 5, and avoid interference with the forming space;

[0096] The lower die sleeve 4 is provided with a plurality of groups of delivery channels 401 corresponding to the internal cooling channels 502 on the side surface, each group of delivery channels 401 has two, and is respectively communicated with the inlet and outlet of the corresponding internal cooling channel 502, for providing an input and output channel for the internal cooling channel 502.

[0097] When the injection molding machine starts to work, the cooling liquid can enter the internal cooling channel 502 through one delivery channel 401. In the internal cooling channel 502, the cooling liquid absorbs the heat inside the forming column 5, and is discharged outside the mold through another delivery channel 401.

[0098] Through the above setting, the cooling of the forming column 5 can be realized by circulating cooling liquid, and the cooling and solidification speed of the stirring barrel is promoted from the inside, so as to improve the production efficiency.

[0099] In some embodiments, as shown in the drawings, Figure 7 The lifting mechanism 9 comprises:

[0100] A plurality of stop blocks 905 are installed on the top surface of the push plate 902, for limiting the displacement of the push plate 902, preventing it from contacting the lower die sleeve 4, and avoiding damage to the mold;

[0101] A plurality of supporting springs 906 are correspondingly sleeved on the driving rod 903 and constrained between the stripping plate 6 and the bottom plate 8, which play a role in buffering and damping, and can reduce the impact and vibration of the mold parts during the up and down movement.

[0102] Through the above setting, the stability of the mold during long-term operation is improved, and the quality of the molded parts is ensured.

[0103] In some embodiments, as shown in the drawings, Figures 1-3 The locking block 11 and the plurality of locking strips 12 are arranged as follows:

[0104] The locking block 11 is vertically arranged, and the upper end is detachably connected with the upper die sleeve 2, and the lower end is detachably connected with the stripping plate 6, and the two ends are preferably threadedly connected through locking bolts, which ensures the stability of the connection and facilitates disassembly and assembly;

[0105] The plurality of locking strips 12 are arranged vertically, and the upper ends are detachably connected with the upper die sleeve 2, and the lower ends are detachably connected with the lower die sleeve 4, preferably through threaded connection by locking bolts, which guarantees the stability of the connection and facilitates disassembly and assembly.

[0106] Through the above arrangement, uniform locking force can be provided, and it is ensured that each part can be tightly combined together when the mold is closed, thereby preventing leakage or flash of the injection molding material during the injection molding process, so as to improve the quality of the molded part and the stability of the production process.

[0107] In some embodiments, as shown in Figure 8 The plurality of guide columns 13 are installed on the top surface of the side plate 7 and pass through the lower die sleeve 4, the stripper plate 6 and the upper die sleeve 2 upwards.

[0108] Preferably, the stripper plate 6 and the upper die sleeve 2 are both provided with sliding sleeves matched with the guide columns 13, so as to improve the sliding smoothness.

[0109] Through the above arrangement, positioning and guiding effects are provided, and it is ensured that the stripper plate 6 and the upper die sleeve 2 can be accurately aligned and moved during the opening and closing of the mold, thereby avoiding misalignment or deviation, so as to ensure the precision and quality of the molded part; and the mold structure is also supported and stabilized, which helps to prevent the mold from being deformed or damaged during the injection molding process, thereby prolonging the service life of the mold.
