Description
A mold for a protective cover for a ventilator tubing interface Technical Field
[0001] This utility model relates to the field of ventilator manufacturing technology, specifically to a mold for a protective cover for a ventilator tubing interface. Background Technology
[0002] A ventilator is a device that can replace, control, or alter a person's normal physiological breathing, increase ventilation, improve respiratory function, reduce respiratory effort, and conserve cardiac reserve. A typical ventilator generally consists of a main unit and a tubing system. The main unit houses the control system, air supply system, and other components. The main unit has a housing to accommodate the control system, air supply system, and other components. Different ventilator models have different shapes and structures for their components. When different appearance designs, tubing designs, control panels, or additional functions are adopted, the ventilator's housing structure needs to be modified accordingly. When the tubing interface has exposed parts, protective measures are needed to extend its service life and prevent impact damage. This is usually achieved by installing a protective cover at the tubing interface. If the tubing interface has a curved structure, a protective cover as shown in Figure 8 is required. This protective cover is designed with a corresponding curved structure to effectively protect the curved tubing interface. However, the curved structure of this type of protective cover makes it inconvenient to open the mold after injection molding. Traditional molds are difficult to handle the production of the protective cover, and a special injection molding mold needs to be designed for this type of protective cover. Summary of the Invention

[0026] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0027] Referring to Figures 1-8, this utility model provides a mold for a protective cover for a ventilator tubing interface, including a base 1, a first mold base 2 disposed on the base 1, a second mold base 3 disposed on the first mold base 2, a top plate 4 disposed on the second mold base 3, and a sliding forming mechanism 5. A first mold core 6 is disposed on the first mold base 2, and a second mold core 7 that mates with the first mold core 6 is disposed at the bottom of the second mold base 3. The first mold core 6, the second mold core 7, and the sliding forming mechanism 5 together constitute the forming cavity of the protective cover 9.
[0028] The sliding forming mechanism 5 includes a movable seat 51 movably connected to the second mold base 3, an inclined pull member 52 inserted into the movable seat 51, and a sliding forming member 53 movably connected to the movable seat 51. The sliding forming member 53 is inserted into the second mold core 7, and the sliding forming member 53 and the second mold core 7 are movably connected. The lower end of the inclined pull member 52 is bent outward toward the second mold base 3 to form an inclined portion. The movable seat 51 is provided with an insertion hole that matches the inclined portion. The inclined portion is inserted into the insertion hole. During the mold opening process, when the inclined pull member 52 moves upward, it can push the movable seat 51 to move outward, thereby driving the sliding forming member 53 to move in an obliquely upward direction (with the base 1 as a reference). The bottom surface of the second mold core 7 is provided with a forming recess 71 that matches the protective cover 9. The second mold core 7 is provided with a through-hole 72 for connecting the sliding forming member 53. One end of the through-hole 72 passes through the forming recess 71, and the axis of the through-hole 72 is inclined relative to the base 1. Specifically, during mold closing, the sliding molded part is fully inserted into the second mold core, so that the sliding molded part, the molding recess, and the first mold core together constitute the molding cavity of the product. At this time, the injection molding material is injected into the molding cavity to realize the molding of the product. During mold opening, the sliding molded part moves obliquely upward and separates from the molded product, thereby facilitating demolding.
[0029] As shown in Figure 7, the lower end of the sliding molding part 53 is provided with a first molding surface 54, which together with the molding recess 71 forms a molding area. In addition, the sliding molding part 53 is provided with an injection hole, one end of which is connected to the flow channel of the second mold core 7, and the other end passes through the first molding surface 54, thereby facilitating the injection of injection molding material into the molding cavity.
[0030] As shown in Figure 5, the top surface of the first mold core 6 is provided with a molding protrusion 61 that mates with the molding area. The upper end of the molding protrusion 61 is provided with a second molding surface 62 that mates with the first molding surface 54. Specifically, the shape of the molding protrusion 61 corresponds to the inner contour of the protective cover 9, and its upper end is inclined outwards. That is, the second molding surface 62 is inclined relative to the base 1. During the mold closing process, the sliding molding component 53 is inserted obliquely into the second mold core 7 until the first molding surface 54 reaches the position corresponding to the second molding surface 62. The top surface of the first mold core 6 is also provided with a molding groove 65, which surrounds the bottom edge of the molding protrusion 61. A slag discharge groove 66 is also provided on the outer side of the molding groove 65. The molding groove 65 is used for molding the lower end of the protective cover 9, and the slag discharge groove 66 surrounds the molding groove 65 to ensure that excess injection molding material can quickly flow into the slag discharge groove 66 from all directions.
[0031] The first molding surface 54 is provided with a first groove 55 and a first molding protrusion 56. The upper end face of the protective cover 9 has two through holes, one large and one small, wherein the first molding protrusion 56 is used for molding the smaller through hole.
[0032] The second molding surface 62 is provided with a stepped platform 63, and a boss 64 that mates with the first groove 55 is provided on the stepped platform 63. The stepped platform 63 is used to protect the molding of the larger through hole in the cover 9. During mold closing, the boss 64 can be inserted into the first groove 55 to ensure accurate alignment of the first molding surface 54 and the second molding surface 62.
[0033] Two sliding forming mechanisms 5 are provided, and two forming recesses 71 and two forming protrusions 61 are correspondingly provided. That is to say, this utility model has two forming cavities, and the corresponding structures of the two forming cavities are symmetrically arranged. This utility model can simultaneously form two protective covers 9.
[0034] The second mold base 3 has a limiting member 31 at the position corresponding to the movable seat 51 on its side wall. The limiting member 31 can limit the stroke of the movable seat 51 and prevent the movable seat 51 from completely detaching from the second mold base 3 during the mold opening process.
[0035] The protective cover mold for the ventilator tubing interface also includes a slanted ejector mechanism 8. The slanted ejector mechanism 8 includes a slanted ejector slider 81 connected to the first mold base 2, a slanted ejector member 82 connected to the slanted ejector slider 81, and a pusher block 83 connected to the slanted ejector slider 81. The first mold base 2 is provided with a receiving groove for accommodating the slanted ejector slider 81. The slanted ejector member 82 is used for forming the protruding structure on the inner wall of the protective cover 9. The slanted ejector member 82 passes through the first mold base 2 and is inserted into the second mold core 7. Its end extends to the surface of the formed protrusion 61 (i.e., the second mold core 7 has a pre-set through hole corresponding to the slanted ejector member 82), and together with the surface of the formed protrusion 61, forms a forming surface that matches the inner wall of the protective cover 9. The pusher block 83 has a structure similar to the slanted pull member 52, with its lower end also bent outwards to form an inclined portion. The slanted ejector slider 81 has an insertion hole matching the inclined portion, and the inclined portion is inserted into the insertion hole. During mold opening, the pusher block 83 is pulled by the second mold base 3, thereby pushing the slanted ejector slider 81 to move outwards. The inclined ejector 82 is inclined relative to the base 1, and the upper end of the push block 83 is connected to the second mold base 3. In this embodiment, the sliding molding part 53 corresponding to one of the molding cavities is defined as being set along the direction from the upper left to the lower right, and the inclined ejector 82 is set along the direction from the lower left to the upper right. During the mold opening process after injection molding, the sliding molding part 53 moves towards the upper left, so that the end where the first molding surface 54 is located leaves the molding recess 71, thus avoiding the product demolding. The inclined ejector slider 81 moves outward, driving the inclined ejector 82 to be ejected towards the lower left, thereby enabling the molded product to be demolded quickly.
