Description

Technical Field

[0001] This utility model relates to an injection mold for a filter nozzle of a high-pressure washer. Background Technology

[0002] A high-pressure washer is a machine that uses high-pressure water jets to clean stains. The filter nozzle is located in the main body of the high-pressure washer and is a key component connecting the high-pressure pump and the spray gun. It guides the high-pressure water jet generated by the high-pressure pump to the spray gun through a high-pressure pipeline to perform the cleaning operation. In order to facilitate processing and reduce costs, most filter nozzles are made of plastic. Therefore, the production of filter nozzles depends on matching injection molds and corresponding injection molding machines.

[0003] Because the filter nozzle has internal flow channels and multiple surrounding filter holes on its outer wall to filter impurities and dirt from the water, both the internal and external structures are quite complex. Existing filter nozzle injection molds can only form the internal structure, and demolding is difficult, requiring the addition of multiple auxiliary core-pulling cylinders, which also results in a high failure rate. Furthermore, the filter hole structure requires a secondary processing step after the main filter nozzle structure is formed, making the production process cumbersome and resulting in low production efficiency. Therefore, further improvements are needed. Utility Model Content

[0037] Two symmetrically distributed side forming mechanisms 10 are also provided between the first active module 2 and the second active module 1.

[0038] The first side forming block 101 in the two side forming mechanisms 10 is located between the two first semi-circular cavities 81, and the second side forming block 102 in the two side forming mechanisms 10 is located on the left and right sides of the second moving mold core 8, respectively.

[0039] Each of the three semi-circular concave 82 has a first positioning groove 85 and a second positioning groove 84 respectively opened on the left and right sides of the opening. Correspondingly, each of the first side molding blocks 101 has a first positioning strip 1011 formed outward on the outer wall of the side facing the three semi-circular concave 82, and each of the second side molding blocks 102 has a second positioning strip 1021 formed outward on the outer wall of the side facing the three semi-circular concave 82. Each first positioning strip 1011 and each second positioning strip 1021 are movably disposed in a corresponding first positioning groove 85 and a second positioning groove 84.

[0040] The end of the first positioning bar 1011 is formed with a first locking block 1012 in the direction of the third semi-circular cavity 82, and the end of the second positioning bar 1021 is formed with a second locking block 1022 in the direction of the third semi-circular cavity 82.

[0041] Working principle:

[0042] The first active module 2 and the second active module 1 in the molding module are both installed on the action mechanism of the injection molding machine. The base plate 5 is then installed on the body of the injection molding machine. A cylinder is then installed on the outer wall of the first active module 2, and the extension end of the cylinder is set vertically downward and fixed on the traction block 91.

[0043] When the mold is closed, the extension end of the drive cylinder first extends outward to drive the traction block 91 to move downward. Then, with the help of the seat block 92, the two inner cavity forming units move downward, so that the first core pillar 93 in the two inner cavity forming units extends concentrically into the two third semi-circular cavities 82, and at the same time, the two second core pillars 94 extend concentrically into the two first semi-circular cavities 81, and then the two discs 95 extend concentrically into the two fifth semi-circular cavities 83.

[0044] The operating mechanism first drives the first active module 2 to move backward until the rear outer wall of the first active module 2 and the front outer wall of the shaping module 4 are joined together (existing technology). During this process, the front end of each first insert 11 extends into a corresponding third semi-circular cavity 82 and is distributed around the second core post 94.

[0045] Next, the action mechanism is manipulated to move the second active module 1 and the feed plate 3 backward until the rear outer wall of the second active module 1 and the front outer wall of the first active module 2 are joined together, thereby driving the rear outer wall of the first moving mold core 7 and the front outer wall of the second moving mold core 8 to join together. During this process, the rear end of each second insert 12 extends into a corresponding fourth semi-circular cavity 72 and is distributed around the second core post 94.

[0046] While the second active module 1 moves, it also drives the two traction columns 103 in each side forming mechanism 10 to move synchronously, thereby forcing the first side forming block 101 and the second side forming block 102 to move toward the third semi-circular cavity 82 sandwiched between them. This causes each second positioning bar 1021 to move toward the third semi-circular cavity 82 along a corresponding first positioning groove 85 and a second positioning groove 84, until the first locking block 1012 on the first positioning bar 1011 and the second locking block 1022 on the second positioning bar 1021 extend into the interior of the corresponding third semi-circular cavity 82 and are located on the periphery of the first core column 93.

[0047] Subsequently, the molten material enters through the gate in the feed plate 3 and the runner in the second active module 1 between each first semicircular cavity 81 and a corresponding second semicircular cavity 71, between each third semicircular cavity 82 and a corresponding fourth semicircular cavity 72, and between each fifth semicircular cavity 83 and a corresponding sixth semicircular cavity 73, and after cooling, two filter nozzles are formed (prior art).

[0048] Then, the second active module 1 and the feed plate 3 are driven forward by the action mechanism to move away from the first active module 2. Similarly, each first side forming block 101 and each second side forming block 102 are reversed and reset. At the same time, the rear end of each second insert 12 is driven away from the corresponding fourth semi-circular cavity 72. Then, the first active module 2 is driven forward by the action mechanism to move away from the shaping module 4. This causes the first moving mold core 7 and the second moving mold core 8 to separate from each other. At the same time, the front end of each first insert 11 is driven away from the corresponding third semi-circular cavity 82. Then, the extension end of the drive cylinder is retracted inward to move the two inner cavity forming units upward and reset. Finally, the two formed filter nozzles are pushed forward by the pusher mechanism 6 (existing technology).

[0049] This invention optimizes the core-pulling method and the parting surface position. By using the two-stage mold-closing process of the first active module 2 and the second active module 1 in the molding module, and in conjunction with the inner core molding component 9, the internal and external structures of the filter tip are molded in one go. This reduces the difficulty of demolding and the failure rate, and simplifies the production process to improve production efficiency.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
