Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum alloy handle production, in particular to a mold release agent spraying device for die-casting of aluminum alloy handles. Background Art
[0002] Aluminum alloy handles are widely used in home decoration, electrical appliances and other fields. Due to their uniform size and complex decorative patterns on the surface, aluminum alloy handles are generally produced by die-casting. Before die-casting, a release agent needs to be sprayed into the mold cavity.
[0003] The existing release agent spraying equipment cannot judge the distance from the mold cavity by itself, resulting in uneven release agent spraying. In addition, the spraying equipment has a fixed length, making it difficult to spray the release agent on the inner walls of the mold cavities on both sides at the same time. If simultaneous spraying on both sides is required, sufficient pipe length must be reserved. If the pipe is too long, the pipes will be entangled with each other, which will cause the pipes to be pulled during the control of the expansion and contraction process, resulting in knots or even breaks. Therefore, the pipes need to be effectively organized. Utility Model Content

DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.
[0025] like Figure 1-7 The mold release agent spraying device for die-casting of an aluminum alloy handle shown in the figure comprises a control box 1, a connecting frame 2, a double-headed oil cylinder 3, a fixing frame 4, a mounting plate 5, a distance sensor 6, a nozzle 7, a connecting plate 8, a clamping claw 9, a sorting component 10 and a guide tube 11. The connecting frame 2 is fixedly arranged inside the control box 1, a mounting hole is opened in the middle of the connecting frame 2, the double-headed oil cylinder 3 is installed in the mounting hole in the middle of the connecting frame 2, the fixing frame 4 is sleeved and fixed to the telescopic end of the double-headed oil cylinder 3, the mounting plate 5 is fixedly arranged on the outside of the fixing frame 4, the distance sensor 6 and the nozzle 7 are arranged on the outside of the mounting plate 5, the connecting plate 8 It is fixedly arranged on the inner side of the control box 1, the claw 9 is fixedly arranged on the upper surface of the connecting plate 8, the sorting component 10 is arranged on the inner side of the claw 9, one end of the guide tube 11 is arranged at the tail end of the nozzle 7, and the other end thereof is clamped into the inside of the sorting component 10, and the sorting component 10 includes a shell 101, a guide rod 102, a spring 103, a sliding block 104 and a clamping shaft 105. The shell 101 is clamped and fixed on the inner side of the claw 9, the guide rod 102 is fixedly arranged on the inner side of the shell 101, the spring 103 and the sliding block 104 are sleeved on the outer side of the guide rod 102, and the clamping shaft 105 is arranged on the top of the sliding block 104.
[0026] Specifically, a circular arc groove cooperating with the guide tube 11 is provided on the surface of the card shaft 105, guide strips are provided on the top of the card shaft 105 and the bottom of the sliding block 104, and guide grooves cooperating with the guide strips are provided on the inner side of the top and the inner side of the bottom of the shell 101. The guide tube 11 is sleeved on the outside of the card shaft 105, and is located in the sorting component 10 in an S shape. One end of the guide tube 11 passes through the sorting component 10 and extends to the outside of the control box 1. The distance sensor 6 is arranged in the middle and around the mounting plate 5, and the nozzle 7 is located on the outside of the mounting plate 5, distributed in a matrix, an operating lever is provided on the top of the control box 1, and the vertical section of the connecting frame 2 is an I-shaped structure.
[0027] In this embodiment, the device controls the movement of the entire release agent spraying device through the operating lever on the top of the control box 1. After the mold is separated and the internal die-cast handle is taken out, the control device moves the release agent spraying device between the concave and convex molds, and then detects the distance between the nozzle and the mold cavity through the distance sensor 6. The mounting plate 5 is adjusted forward and backward through the extension and retraction of the telescopic end of the double-headed oil cylinder 3 to change the spraying distance and ensure the spraying effect. Subsequently, the high-pressure release agent is sprayed out from the nozzle 7 after passing through the guide tube 11 and sprayed on the surface of the mold cavity, thereby spraying at the rated distance to ensure the spraying effect.
[0028] Furthermore, the mounting plate 5 is effectively fixed by the fixing frame 4 at the telescopic end of the double-headed oil cylinder 3. When the double-headed oil cylinder 3 is telescoped and drives the mounting plate 5 to move forward and backward, the guide tube 11 on the back of the mounting plate 5 and connected to the tail end of the nozzle 7 needs to freely telescope with the forward and backward movement of the mounting plate 5. In order to avoid the intertwining of the guide tubes 11 and to avoid the guide tubes 11 being pulled too much during the telescopic process so as to cause the pipes to fall off or break, each guide tube 11 needs to be arranged. A single guide tube 11 can be arranged by an arrangement component 10. The arrangement component 10 is installed by a connecting plate 8 fixed to the inner side of the control box 1. The connecting plate 8 The claw 9 at the top clamps the sorting component 10 to fix it. When the guide tube 11 needs to be pulled out, the sliding block 104 is subjected to tension to squeeze the spring 103, causing the spring 103 to shrink under pressure. The sliding block 104 slides on the surface of the guide rod 102, thereby reducing the guide tubes 11 stored inside the sorting component 10. When the double-headed cylinder 3 shrinks, the sorting component 10 needs to store the excess guide tubes 11 inside it. At this time, the spring 103 relaxes and pushes the sliding block 104 to reset, and the clamping shaft 105 stores the excess guide tubes 11 into the sorting component 10, thereby effectively avoiding the problem of too many guide tubes 11 being exposed and entangled with each other.
[0029] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
