Description

Technical Field

[0001] This utility model relates to the field of injection molding head cleaning technology, specifically a cleaning device for injection molding heads. Background Technology

[0002] In the injection molding process, the injection head is a key component of the injection molding equipment, responsible for injecting molten injection material into the mold. However, after injection, the nozzle and internal cavity of the injection head often have residual injection material. If this residual material is not cleaned in time and thoroughly, it will gradually solidify over time. This will affect the flowability of the material during subsequent injections, leading to a decrease in injection precision and making it difficult to guarantee product quality. Therefore, it is necessary to clean the injection head regularly.

[0003] Currently, most methods for cleaning injection molding heads rely on manual brushing with chemical cleaning agents. This manual cleaning is not only inefficient, but also prone to incomplete cleaning due to the small diameter of the injection molding head's internal channels, resulting in inconsistent cleaning effects and other shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for injection molding heads to solve the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for injection molding heads, comprising a housing, a liquid outlet connector being installed through one side plate of the housing, a water pump being installed on the outer wall of one side of the housing, a housing cover being installed on the top of the housing, a connecting cylinder being fixedly installed through the housing cover, a nozzle mounting assembly being installed on the connecting cylinder, the nozzle mounting assembly comprising a cavity column and a threaded adapter, a liquid inlet connector communicating with the cavity of the cavity column being installed on one side, a threaded hole for threaded installation of the threaded adapter being provided at the bottom of the cavity column, the threaded adapter being threadedly connected in the threaded hole, a cover hole being provided at the center of the top surface of the cavity column, the cover hole and the threaded hole at the bottom of the cavity column being interconnected with the cavity of the cavity column, and the cover hole and the threaded hole at the bottom of the cavity column being coincident with the cavity axis of the cavity column, an internal thread being provided on the inner wall of the connecting cylinder, a threaded portion being provided on the outer wall at the bottom of the cavity column, and the cavity column being threadedly installed on the connecting cylinder.

[0006] Preferably, it also includes a brushing assembly, which includes a second cover, a rotating column, and a columnar brush. The rotating column is rotatably mounted through a bearing at the center of the top surface of the second cover. A columnar brush is installed at the bottom end of the rotating column. The columnar brush is composed of fine iron wire and bristles, with the bristles disposed on the outer wall of the fine iron wire.

[0007] Preferably, it also includes a first cap, which has the same dimensions as the rotating column and is adapted to the thread of the cap hole.

[0008] Preferably, a filter screen is installed at one end of the liquid outlet connector located inside the tank, the input end of the water pump is connected to one end of the liquid outlet connector through a pipe, and the output end of the water pump is connected to one end of the liquid inlet connector through a pipe.

[0009] Preferably, the lid is hinged with a liquid injection door, a sponge layer is provided at the bottom of the box, the box is transparent, and the lid is installed on the box with screws at the four corners.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model has a clever structure. By setting up a box, a nozzle mounting assembly, and a water pump, the injection head that needs to be cleaned is mounted on the nozzle mounting assembly. The water pump can introduce chemical cleaning agent into the nozzle mounting assembly and then spray it out from the nozzle of the injection head. The flowing chemical cleaning agent washes away the residue on the injection head, achieving cleaning. Compared with manual cleaning, it is more efficient, and the chemical cleaning agent can be recycled, reducing cleaning costs.

[0012] The device also includes a brush assembly. The brush assembly is installed on the nozzle mounting assembly, allowing the columnar brush to extend into the injection head cavity. Rotating the rotating column causes the columnar brush to rotate, brushing the cavity to further remove residue and improve the cleaning effect. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a cleaning device for injection molding heads, comprising a housing 1, a liquid outlet connector 5 installed through one side plate of the housing 1, a water pump 4 installed on the outer wall of one side of the housing 1, a housing cover 2 installed on the top of the housing 1, a connecting cylinder 21 fixedly installed through the housing cover 2, a nozzle mounting assembly 3 installed on the connecting cylinder 21, the nozzle mounting assembly 3 comprising a cavity column 31 and a threaded adapter 33, a liquid inlet connector 32 communicating with the cavity is installed on one side of the cavity column 31, and a thread is provided at the bottom of the cavity column 31 for threaded installation of the threaded adapter 33. The threaded adapter 33 is threaded into the threaded hole, which facilitates the replacement of the threaded adapter 33 with injection heads of different thread diameters. The top surface of the cavity column 31 has a cover hole 3101. The cover hole 3101 and the threaded hole at the bottom of the cavity column 31 are interconnected with the cavity of the cavity column 31, and the cover hole 3101 and the threaded hole at the bottom of the cavity column 31 coincide with the axis of the cavity of the cavity column 31. The inner wall of the connecting cylinder 21 has an internal thread, and the outer wall at the bottom of the cavity column 31 has a threaded part 3102. The cavity column 31 is threadedly installed on the connecting cylinder 21.

[0021] Furthermore, it also includes a brush assembly 7, which includes a second cover 71, a rotating column 72 and a columnar brush 73. The rotating column 72 is rotatably mounted through the center of the top surface of the second cover 71 via a bearing. The columnar brush 73 is installed at the bottom end of the rotating column 72. The columnar brush 73 is composed of fine iron wire and bristles, with the bristles arranged on the outer wall of the fine iron wire.

[0022] Furthermore, it also includes a first cover 6, which is the same size as the rotating column 72 and is threaded to fit the cover hole 3101; a filter screen is provided at one end of the liquid outlet connector 5 located inside the box 1; the input end of the water pump 4 is connected to one end of the liquid outlet connector 5 through a pipe, and the output end of the water pump 4 is connected to one end of the liquid inlet connector 32 through a pipe; a liquid injection door is hinged on the box cover 2; a sponge layer is provided at the bottom of the box 1, and the box 1 is a transparent box. The sponge layer inside the box 1 can buffer the force of the nozzle impacting the bottom of the box 1 when cleaning the injection nozzle, reducing the generation of noise. The transparent box 1 makes it easy to observe the amount of cleaning agent and the cleaning status inside the box.

[0023] The working process of this utility model is as follows:

[0024] like Figure 1 - Figure 4 As shown, when in use, open the injection door, add chemical cleaning agent for cleaning injection molding nozzles into the housing 1, thread the nozzle to be cleaned onto the adapter 33 of the nozzle mounting assembly 3, and then thread the entire nozzle mounting assembly 3 onto the connecting cylinder 21 through the threaded part 3102.

[0025] When only chemical cleaning agent is needed for rinsing, the first cap 6 is threaded onto the cap hole 3101 to seal the cap hole 3101. When the water pump 4 is working, the chemical cleaning agent filtered through the filter screen in the tank 1 is introduced through the liquid outlet connector 5, and then transported through the pipeline to the liquid inlet connector 32, and then enters the cavity of the cavity column 31, and is then sprayed out by the nozzle of the injection molding nozzle. During this process, the flowing chemical cleaning agent will wash away the residue adhering to the injection molding nozzle, and the washed cleaning agent falls back into the tank 1 for recycling.

[0026] When further brushing and cleaning is required, remove the first cover 6 and thread the second cover 71 of the brushing assembly 7 onto the cover hole 3101. At this time, the columnar brush 73 extends into the cavity of the injection nozzle. Rotating the rotating column 72 will cause the columnar brush 73 to rotate synchronously. The bristles of the columnar brush 73 brush the nozzle cavity to further remove the adhering residue.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
