Description

Technical Field

[0001] The present invention relates to the technical field of medical respiratory equipment, and in particular to a medical respiratory equipment and its manufacturing device. Background Art

[0002] Medical respiratory equipment refers to various medical equipment that directly or indirectly contacts the human body and has an auxiliary breathing function. There are many types of medical respiratory equipment, and the most widely used one is the medical respiratory mask, which is indispensable in aspects such as anesthesia and respiration. The main material of the medical respiratory mask is silicone, and the medical respiratory mask is generally formed by injection processing.

[0003] The medical respiratory mask is formed by silicone injection processing. Before injection processing, it is necessary to manually apply a mold release agent to the surface of the convex template to facilitate the rapid detachment of the silicone part from the convex template after molding. However, manual application takes a certain amount of time and it is difficult to ensure that the surface of the convex template is evenly coated completely, thus affecting the demolding of the silicone part and ultimately affecting the quality of the silicone part, resulting in a low processing efficiency of the device. The injection raw materials of the silicone part are A glue and B glue mixed in equal proportions. During the material taking process, as the content of A glue and B glue decreases, it is difficult to ensure that the material taking parts can always take A glue and B glue smoothly, resulting in the inability of A glue and B glue to be mixed in equal proportions and the silicone part unable to solidify.

A rubber protective sleeve 554 is fixedly installed on the outer surface of the liquid retaining ring 553; the heat insulation piece 551 prevents heat from being transferred to the sealing ring 552 and the rubber protective sleeve 554, thereby causing the sealing ring 552 and the rubber protective sleeve 554 to deform in a high-temperature environment. The rubber protective sleeve 554 on the liquid retaining ring 553 is closely attached to the fitting conical ring 661 to prevent cooling water from overflowing.

[0038] Refer to Figure 5, an arc-shaped groove 611 that matches the convex template 53 is provided on the lower end surface of the concave template 61. A coding groove 612 is provided on the front side of the inner end of the arc-shaped groove 611. A coding block 613 is clamped in the coding groove 612. An authentication mark groove and a coding groove are provided at the rear end of the coding block 613. Concave grooves 614 are symmetrically provided on the left and right sides of the lower end of the arc-shaped groove 611; through the cooperation of the arc-shaped groove 611 and the arc-shaped convex block 532, the breathing mask 1 is shaped.

[0040] Refer to Figure 7 , the coating liquid rack 68 includes a support plate 681. Support plates 681 are symmetrically and fixedly installed on the left and right sides of the upper end of the fixing plate 50. A coating agent plate 682 is rotatably connected to the upper end of the support plate 681 through a pin shaft. A torsion spring 683 is sleeved on the pin shaft.

Coating agent brushes 684 are evenly fixedly installed on the lower end surface of the coating agent plate 682. Agent storage boxes 685 are fixedly installed at the upper ends of the coating agent plates 682 on the left and right sides. Conical through holes 686 are evenly provided on the lower end surface of the coating agent plate 682. The bottom area of the upper side of the conical through hole 686 is larger than the bottom area of the lower side. A tower-shaped spring 687 is fixedly installed in the conical through hole 686. A conical sealing block 688 is fixedly installed at the lower end of the tower-shaped spring 687. The bottom area of the upper side of the conical sealing block 688 is larger than the bottom area of the lower side. Felt blocks 689 are evenly fixedly installed on the lower end surface of the coating agent brushes 684; when the convex template 53 moves to the coating liquid rack 68, the conical sealing block 688 is squeezed by the convex template 53, thereby squeezing the tower-shaped spring 687. The release agent in the agent storage box 685 overflows from the gap between the conical through hole 686 and the conical sealing block 688. The overflowing release agent is absorbed by the felt blocks 689 and the coating agent brushes 684, and at the same time contacts the surface of the convex template 53, so that the surface of the convex template 53 is coated with the release agent.

[0041] Refer to Figure 2 、 Figure 6 and Figure 9, the packaging box 74 includes a rectangular box body 741. Sliding track grooves 742 are evenly formed in the rectangular box body 741. A sliding block 743 is connected to the sliding track grooves 742 in a sliding fit manner. The sliding blocks 743 located in the same packaging box 74 are commonly fixedly installed with a rectangular material pressing plate 744. A fixed pipe groove 745 is formed at the bottom of the rectangular box body 741. The upper end of the fixed pipe groove 745 is provided with a rounded corner. Positioning stoppers 746 are evenly fixedly installed at the upper end of the fixed pipe groove 745. An annular positioning member 747 is commonly fixedly installed at the upper ends of the positioning stoppers 746. Matching tooth grooves 748 are evenly formed at the inner end of the annular positioning member 747. The volumes of adjacent matching tooth grooves 748 are different. By means of the sliding block 743, it is ensured that the rectangular material pressing plate 744 is always in contact with the upper end surface of the A glue or B glue in the rectangular box body 741. By means of the positioning groove, it is ensured that the material suction pipe 76 can always suck and transport the A glue or B glue. The lower side of the material suction pipe 76 is positioned by the positioning stopper 746 and the annular positioning member 747 to prevent the material suction pipe 76 from separating from the positioning groove.

[0042] Refer to Figure 6 And Figure 9 , the material suction pipe 76 includes a main suction pipe 761. The main suction pipe 761 is fixedly installed at the lower end of the control pump 75.

Matching tooth blocks 765 are evenly fixedly installed at the outer end of the flower-shaped pipe 763. The volumes of adjacent matching tooth blocks 765 are different. The A glue or B glue can smoothly enter the flower-shaped pipe 763 through the flower-shaped groove 764 on the flower-shaped pipe 763. Since the lower end of the rectangular material pressing plate 744 changes with the height of the upper end surface of the A glue or B glue, the distance between the flower-shaped pipe 763 and the main suction pipe 761 is ensured to be changeable under the action of extrusion force by means of the cylindrical spring 762. It is ensured that the flower-shaped pipe 763 is difficult to separate from the annular positioning member 747 without manual operation by means of the matching tooth blocks 765 with different volumes.

[0043] During specific operation, first, the moving cylinder 51 drives the positioning plate 52 to move upward. When the convex template 53 moves to the liquid coating rack 68, the liquid coating rack 68 applies a release agent to the surface of the convex template 53. At this time, the moving cylinder 51 continues to drive the convex template 53 to move upward until the convex template 53 contacts the concave template 61. At this time, the convex template 53 and the concave template 61 heat the cavity to ensure that the temperature in the cavity is 200 °C. The control pump 75 drives the suction pipe 76 to transport the A glue and B glue in the containing box 74 to the static mixer 72. The static mixer 72 fully and evenly mixes the A glue and B glue. Finally, the injection machine 71 transports the evenly mixed A glue and B glue to the conical flow channel 67 and finally into the cavity. After a period of pressure holding and heat preservation, the water pump 64 drives the cooling water to circulate reciprocally in the return pipeline composed of the first flow channel hole 54, the second flow channel hole 62, the water delivery pipe 63, and the spiral cooling pipe 65, so as to cool down the breathing mask 1 in the cavity and make it solidify. Finally, the ejecting cylinder 56 drives the arc-shaped frame plate 57 to move upward, driving the ejecting pin column 58 to move upward to eject the breathing mask 1, and the support column 59 positions between the convex template 53 and the concave template 61.
