Description

Technical Field

[0001] This utility model belongs to the technical field of fixed impeller processing, and in particular relates to a fixed impeller injection mold. Background Technology

[0002] A fixed impeller is a type of power machinery that uses continuously rotating blades as its main body to convert energy between a fluid working medium and shaft power. Unlike reciprocating piston machinery, which confines the working medium in a variable-volume space, fixed impellers are open to the environment, thus possessing a stronger flow capacity and providing an effective way to significantly increase the power of the machinery. Therefore, in the processing of fixed impellers, corresponding fixed impeller molds are required.

[0003] However, existing fixed impeller molds lack the ability to heat the injection molding process, leading to rapid cooling and potential blockage of the flow channels. Furthermore, the absence of a positioning and limiting function for the molded structure during injection molding compromises stability. Therefore, we provide a fixed impeller injection mold to address these issues. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1 to 10 This utility model is a fixed impeller injection mold. The injection process is heated by heating plate 705 to ensure injection efficiency and avoid blockage caused by rapid cooling. At the same time, the first molding block 702 and the second molding block are respectively set inside the second positioning hole 804 and the first positioning hole 803 to ensure the stability of injection molding.

[0033] Specifically, the base plate 1 has support blocks 2 on the front and rear of the upper surface of the base plate 1, and a processing block 3 that abuts against the upper surfaces of the two support blocks 2 is provided on the top of the base plate 1. A linkage block 4 is provided on the upper surface of the processing block 3, a connecting plate 5 is provided on the upper surface of the linkage block 4, and a top plate 6 is provided on the upper surface of the connecting plate 5.

[0034] Among them, the upper end face of the processing block 3 is provided with an assembly port 301, the lower end face of the linkage block 4 is provided with an installation port 401 with the same shape and size as the assembly port 301, the upper end face of the processing block 3 is provided with a module 1 8 located inside the installation port 401, the lower end face of the module 1 8 is provided with a module 2 801 located inside the assembly port 301, the upper end face of the module 2 801 is provided with a square opening 802, the bottom of the square opening 802 is provided with a plurality of positioning holes 1 803 arranged in an array, the upper end face of the module 1 8 is provided with positioning holes 2 804 at the positions corresponding to the positioning holes 1 803, and an injection cylinder 7 is provided directly above the module 1 8.

[0035] The lower end face of the injection molding cylinder 7 is provided with a special-shaped block 701 that connects to the upper end face of module 8. A heating element 705 is fixed at the lower end face of the special-shaped block 701 corresponding to the position of the positioning hole 804. A plastic block 702 is fixed at the lower end face of the heating element 705 and is inserted into the position of the positioning hole 804. A plastic block 703 is provided at the lower end face of the plastic block 702 and is inserted into the position of the corresponding positioning hole 803.

[0036] The operation process of this embodiment is as follows: Using the above-described structure, molten liquid is injected into the corresponding molding blocks 702 and 703 through the injection molding cylinder 7. The molding blocks 702 and 703 work together to mold them into a fixed impeller shape. During the molding process, the heating element 705 is controlled to heat the injection process, preventing cooling and potential blockage of the injection tube 706. Simultaneously, molding block 702 is installed inside the positioning hole 804, and molding block 703 is installed inside the positioning hole 803. Therefore, positioning holes 804 and 803 position molding blocks 702 and 703, ensuring stable assembly and thus achieving stable injection molding.

[0037] Example 2

[0038] Please see Figure 3 , Figure 9 and Figure 10 Based on Example 1, the assembly rod 201 and the locking screw 202 are used together to facilitate disassembly, thereby improving the demolding efficiency.

[0039] Specifically, the front and rear ends of the support block 2 are fixed with assembly rods 201. The processing block 3 is fitted onto the assembly rod 201 through the insertion hole 302 opened through the end corner. The linkage block 4 is fitted onto the assembly rod 201 through the assembly hole 403 opened through the end corner. The connecting plate 5 is fitted onto the assembly rod 201 through the abutment hole 502 opened through the end frame. The top plate 6 has a locking hole 602 at the end corner that is smaller than the diameter of the assembly rod 201. The lower end face of the top plate 6 abuts against the upper end face of the assembly rod 201. The locking hole 602 is provided with a locking screw 202 that is spirally connected to the upper end face of the assembly rod 201.

[0040] The operation process of this embodiment is as follows: by rotating the locking screw 202 on the upper end face of the assembly rod 201, the top plate 6 and the connecting plate 5 are no longer in an assembly relationship, and the top plate 6 can be disassembled. This makes it easy to slide the connecting plate 5, the linkage block 4 and the processing block 3 upward along the assembly rod 201 to carry out the disassembly work. At the same time, after the linkage block 4 and the processing block 3 are separated from the assembly relationship, the first module 8 and the second module 801 will be separated, and the first molding block 702 and the second molding block 703 will be separated, thereby improving the demolding efficiency.

[0041] Example 3

[0042] Please see Figure 4 , Figure 5 , Figure 9 and Figure 10 Based on Example 1, multi-station molding is performed by using the converging cylinder 601, the injection cylinder 7, and the injection tube 706 in combination.

[0043] Specifically, a positioning plate 704 is located directly below the irregular block 701 and inside the square opening 802. The middle part of the second molding block 703 is fixedly connected to the positioning plate 704. The upper end face of the linkage block 4 has an irregular opening 402 that communicates with the inside of the mounting opening 401. The irregular block 701 is inserted into the irregular opening 402. The injection cylinder 7 is connected to the inside of the first molding block 702 through the injection tube 706 fixedly connected to the lower end face. The upper end face of the connecting plate 5 has a groove 501 that communicates with the irregular opening 402. The injection cylinder 7 is located inside the groove 501. The upper end face of the top plate 6 is fixed with a converging cylinder 601 that is aligned with the vertical position of the injection cylinder 7.

[0044] The operation process of this embodiment is as follows: After the use of the collecting cylinder 601, the melt can be poured from the inside of the collecting cylinder 601 and then flows directly into the injection cylinder 7. Furthermore, the connection between the injection tube 706 and the molding block 702 allows the melt to be diverted from the injection tube 706 to the corresponding molding block 702, thereby performing multi-station molding processing.

[0045] Example 4

[0046] Please see Figure 3 , Figure 8 , Figure 9 and Figure 10 Based on Example 1, the processing block 3 and the assembly block can be quickly assembled and disassembled by using the elastic spiral plate 101 and the elastic rod 102 together.

[0047] Specifically, multiple elastic spiral plates 101 arranged in an array are fixed on the upper surface of the base plate 1 located between the two support blocks 2, and the elastic spiral plates 101 abut against the bottom of the processing block 3. Two symmetrically arranged through holes 203 are opened on the upper surface of the support block 2 located between the two assembly rods 201. An elastic rod 102 passing through the inside of the through hole 203 is fixed on the upper surface of the base plate 1. A movable hole 303 is opened on the processing block 3 at the position corresponding to the elastic rod 102. The end of the elastic rod 102 passing through the movable hole 303 abuts against the bottom of the linkage block 4.

[0048] The operation process of this embodiment is as follows: when the top plate 6 is disassembled, the elastic rod 102 will directly push the linkage block 4 to slide upward, so that the linkage block 4 is disengaged from the processing block 3, and the elastic spiral plate 101 will push the processing block 3 to disengage from the support bar, thereby realizing the rapid disassembly work.
