Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically a three-hole suction cylinder mold for a nasal aspirator. Background Technology

[0002] A nasal aspirator is a nasal cleaning tool specifically designed for infants and young children, primarily used to help remove secretions from the nasal cavity. The industry mainly uses traditional multi-plate injection molds or slider-type core-pulling molds to manufacture the suction tube components. The complex hollow cavity, threaded structure, and lateral liquid inlet / outlet ports inside the suction tube are formed through the opening and closing of multiple platens and the lateral core-pulling movement of the slider mechanism. Existing molds used for producing nasal aspirators suffer from the following prominent problems and limitations: low production efficiency, long production cycle, difficulty in demolding, and workpiece quality defects. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a three-hole suction cylinder mold for a nasal aspirator, which improves production efficiency while ensuring manufacturing quality.

[0004] The objective of this utility model can be achieved through the following technical solutions: A three-hole suction cylinder mold for a nasal aspirator includes a heat insulation plate, a flow divider plate, an upper template, a lower template, side plates, a fixing plate, support columns, a top plate, a heightening plate, and a bottom plate. The heat insulation plate is fixedly connected to the flow divider plate, and the heat insulation plate has a feed inlet at its center. The flow divider plate is fixedly connected to the upper template, and the flow divider plate has a hot runner inside. A flow divider is located above the upper template. The left and right halves of the lower template are respectively connected to two side plates, and the other end of the side plates is connected to the bottom plate. The right side plate of the two side plates has two clearance grooves. A heightening plate is fixed on the bottom plate. Two support columns are provided between the lower template and the bottom plate. The fixing plate and the top plate are located between the lower template and the heightening plate and are fixed by the support columns. The upper template contains an upper module, and the lower template contains a lower module. The left half of the lower module has a left mold slider, and the right half has a right mold slider. The left mold slider has a protruding left mold protrusion at the opposite side, and the right mold slider has a protruding right mold protrusion on the opposite side. The lower module has several through holes, through which several corresponding core rods pass. The lower end of the core rod is fixed in the heightening plate. The core rod, the left mold protrusion, the right mold protrusion, the upper module, and the lower module together form the processing cavity of the workpiece. The left and right mold sliders are provided with outwardly inclined left and right guide pillars. The upper end of the left guide pillar passes through the upper mold plate and abuts against the flow divider plate, and the lower end passes through the left mold slider to the lower mold plate. The upper end of the right guide pillar passes through the upper mold plate and abuts against the flow divider plate, and the lower end passes through the right mold slider and the lower mold plate to the relief groove above the right side plate. The core rod is fitted with an ejector rod. The upper end of the ejector rod abuts against the workpiece, and the lower end passes through the fixing plate and is fixed on the ejector plate.

[0005] After the workpiece injection molding is completed, the upper mold plate is lifted, the left mold plate moves to the left along the left guide rail, the right mold plate moves to the right along the right guide rail, and the top plate moves upward under the action of the drive device, driving the top rod to move upward, thus completing the unloading process.

[0006] Furthermore, the ejector rod is a cylinder with the same diameter as the through hole diameter of the workpiece. The ejector rod can move up and down along the core rod, and eject the workpiece from the core rod after processing.

[0007] Furthermore, anti-slip blocks are provided on the outer sides of the left and right mold sliders. The anti-slip blocks allow the left and right mold sliders to slide along the left and right guide pillars respectively, thereby preventing displacement during mold parting and thus preventing extrusion deformation of the workpiece.

[0008] Furthermore, the length of the right mold protrusion is greater than the length of the left mold protrusion.

[0009] Furthermore, the length of the right guide post is greater than the length of the left guide post. This longer right guide post allows the right mold slider to move a greater distance to the right.

[0010] Compared with the existing technology, the advantages of this utility model are: high efficiency: it can process several workpieces at the same time, and the ejector rod on the core rod can quickly remove the material after injection molding, thus shortening the production cycle.

[0011] High quality: Through the cooperation of multiple modules, the integrity of the workpiece structure and the accuracy of its dimensions are ensured, reducing the risk of damage during the demolding process. Attached Figure Description

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1 to 5 As shown, a three-hole suction cylinder mold for a nasal aspirator includes a heat insulation plate 1, a flow divider plate 2, an upper template 3, a lower template 4, a side plate 5, a fixing plate 6, a support column 61, an ejector plate 7, a heightening plate 8, and a bottom plate 9. The heat insulation plate 1 is fixedly connected to the flow divider plate 2, and the heat insulation plate 1 has a central inlet 11 for injecting molten plastic. The flow divider plate 2 is fixedly connected to the upper template 3, and the flow divider plate 2 has a hot runner 21 to maintain the molten plastic. A flow guide groove 31 is provided between the upper template 3 and the flow divider plate 2 to guide the plastic into the mold cavity. The fixing plate 6 and the ejector plate 7 are located between the lower template 4 and the heightening plate 8 and are fixed by the support column 61.

[0020] The lower template 4 is connected to two side plates 5 at both ends, and the other end of the side plate 5 is connected to the base plate 9. The right side plate 5 has two clearance grooves 471 to accommodate the lower end of the right guide post 47. A heightening plate 8 is fixed on the base plate 9, and two support columns 61 are provided between the lower template 4 and the base plate 9 to support the lower template 4 and maintain structural stability.

[0021] The upper template 3 contains an upper module 32, and the lower template 4 contains a lower module 41. The lower module 41 has a left mold slider 42 on its left half and a right mold slider 43 on its right half. The left mold slider 42 has a protruding left mold protrusion 421 at its opposite position, and the corresponding right mold slider 43 has a protruding right mold protrusion 431 at its opposite position. The lower module 41 has several through holes through which several corresponding core rods 48 pass, and the lower ends of the core rods 48 are fixed inside the extension plate 8. The core rods 48, the left mold protrusion 421, the right mold protrusion 431, the upper module 32, and the lower module 41 together form the processing cavity of the workpiece 45.

[0022] The left mold slider 42 and the right mold slider 43 are provided with outwardly inclined left guide post 46 and right guide post 47. The upper end of the left guide post 46 passes through the upper mold plate 3 and abuts against the flow divider plate 2, and the lower end passes through the left mold slider 42 into the lower mold plate 4. The upper end of the right guide post 47 passes through the upper mold plate 3 and abuts against the flow divider plate 2, and the lower end passes through the right mold slider 43 and the lower mold plate 4 to the relief groove 471 above the right side plate 5. The core rod 48 is fitted with an ejector rod 49.
