Description

Technical Field

[0001] This utility model relates to the field of ventilator manufacturing technology, specifically to a ventilator housing mold. Background Technology

[0002] A ventilator is a device that can replace, control, or alter a person's normal physiological breathing, increasing ventilation, improving respiratory function, reducing respiratory effort, and conserving 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 shell structure to house the control system, air supply system, and other components. The shell structure has several components, including the main body and a cover plate. When the shell structure is made of plastic, it is manufactured using injection molding. However, the specific shape and structure of components vary between different ventilator models. When different appearance designs, tubing designs, control panels, or additional functions are adopted, the ventilator's shell structure needs to be modified accordingly. Figure 7 The ventilator housing shown has a recessed portion at one end of its outer side, with several connecting structures (such as several ribs on the surface of the recessed portion) inside. A box-shaped structure is also provided on the inner side near the middle, and the bottom surface of the box-shaped structure has a recessed portion, causing the bottom surface to bulge out to the other side. This makes it difficult to demold the product after molding. Traditional molds are difficult to handle the molding of this housing, and an injection molding mold needs to be developed specifically for this housing. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a ventilator housing mold that enables rapid production of ventilator housings.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1-7This utility model provides a ventilator housing mold, including a base plate 1, an ejector assembly 11 disposed on the base plate 1, a lower mold base 2 disposed on the ejector assembly 11, an upper mold base 3 disposed on the lower mold base 2, and a top plate 12 disposed on the upper mold base 3. A lower mold core 4 is disposed on the lower mold base 2, and an upper mold core 5 that mates with the lower mold core 4 is disposed at the bottom of the upper mold base 3. A first sliding forming mechanism 6, a second sliding forming mechanism 7, and a third sliding forming mechanism 8 are disposed around the lower mold core 4 on the top surface of the lower mold base 2. A slanted ejector forming mechanism 9 is connected to the lower mold core 4. In this embodiment, the second sliding forming mechanism and the third sliding forming mechanism are arranged on opposite sides. When the mold is closed, the first slider 61 forming mechanism, the second sliding forming mechanism, the third sliding forming mechanism, the lower mold core 4, the upper mold core 5, and the inclined ejector forming mechanism 9 surround and form the forming cavity of the ventilator housing 10. The injection molding material enters the forming cavity from the flow channels of the upper mold base 3 and the upper mold core 5. During the mold opening process after curing, the first slider 61 forming mechanism, the second sliding forming mechanism, and the third sliding forming mechanism move away from the lower mold core 4, and the inclined ejector forming mechanism 9 is pushed out obliquely upward under the drive of the ejector assembly 11, thereby realizing the rapid demolding of the product.

[0026] The inclined ejector forming mechanism 9 includes an inclined ejector 91 connected to the lower mold core 4 and an inclined ejector seat 92 connected to the ejection assembly 11. An inclined ejector rod 93 is provided at the bottom of the inclined ejector 91, passing through the lower mold base 2 and connecting to the inclined ejector seat 92. The inclined ejector rod 93 and the inclined ejector seat 92 are movably connected. The bottom of the ventilator housing 10 has a recessed portion, and the inclined ejector 91 corresponds to this recessed portion to achieve the forming of this recessed portion. In this embodiment, the lifting assembly includes two mold feet disposed on the base and a lifting plate disposed between the two mold feet. The lifting plate has several ejector pins, and the inclined ejector seat 92 is connected to the lifting plate. Figure 2 Taking the mold opening process as an example, the lifting plate pushes out towards the lower mold base 2. Since the inclined ejector 92 and the inclined ejector rod 93 are movably connected, the inclined ejector rod 93 can push out obliquely upward (i.e., push out towards the upper left side), driving the inclined ejector 91 to move obliquely upward. During the movement, the inclined ejector 91 pushes out the product, causing the product to separate from the lower mold core 4. At the same time, the horizontal position of the inclined ejector 91 also moves a certain distance towards the outside of the mold, thereby causing the inclined ejector 91 itself to separate from the product, achieving rapid demolding of the product.

[0027] The first sliding forming mechanism includes a first slider 61 movably connected to the lower mold base 2, a first forming block 62 connected to the first slider 61, a first inclined rod 63 inserted into the first slider 61, and a driving assembly 64 for driving the first slider 61 to move. The upper end of the first inclined rod 63 is connected to the upper mold base 3. During the mold opening process, when the driving assembly 64 is not powered, the inclined rod will drive the first slider 61 to move outward when the upper and lower molds separate, causing the first forming block 62 to separate from the product. Therefore, when the driving assembly 64 provides power to drive the first slider 61 to move outward, it will conversely drive the inclined rod to move upward, causing the upper and lower molds to separate quickly.

[0028] The driving assembly 64 includes a driving base 641 connected to the lower mold base 2, and a driving component 642 disposed on the driving base 641. The output end of the driving component 642 is connected to the first slider 61. In this embodiment, the driving component 642 can be a hydraulic cylinder, which provides a driving force during the mold opening process to ensure rapid and stable demolding.

[0029] The lower mold core 4 is provided with a first forming protrusion 41, the first forming protrusion 41 is provided with a first forming recess 42 corresponding to the box-shaped mechanism of the housing 10, the first forming protrusion 41 is also provided with a receiving portion 43 for accommodating the inclined ejector 91, the bottom of the receiving portion 43 is provided with a through opening 44 that penetrates the lower mold core 4, and the inclined ejector 93 is inserted into the through opening 44.

[0030] The upper mold core 5 is provided with a second molding recess 51 that matches the first molding protrusion 41. One end of the second molding recess 51 is provided with a second molding protrusion 52 that matches the first molding recess 42. The second molding protrusion 52 is provided with a plurality of molding grooves 53 that match the connection structure of the housing 10. In addition, the upper mold core 5 is also provided with a plurality of slag discharge grooves to accommodate excess injection molding material.

[0031] The second molding recess 51 is provided with a plurality of molding posts 54, and the first molding protrusion 41 is provided with molding holes 45 that match the molding posts 54. The surface of the ventilator housing 10 has mounting holes for mounting screws, and the cooperation between the molding posts 54 and the molding holes 45 is used for molding the mounting holes.

[0032] Both the second sliding forming mechanism 7 and the third sliding forming mechanism 8 include a second slider 71 connected to the lower mold base 2, a second forming block 72 connected to the second slider 71, and a second inclined rod 73 connected to the second slider 71. The upper end of the second inclined rod 73 is connected to the upper mold base 3. The operation mode of the second sliding forming mechanism and the third sliding forming mechanism is similar to that of the first slider 61 forming mechanism. When the upper mold pulls the second inclined rod 73, the second slider 71 will move outward, thereby moving away from the product and facilitating product demolding.

[0033] The second sliding forming mechanism 7 further includes a slider forming assembly 74, which includes a third forming block 741 connected to the second slider 71 and a third inclined rod 742 connected to the third forming block 741. The upper end of the third inclined rod is connected to the upper mold base 3, and the second slider 71 and the third forming block 741 are movably connected. The ventilator housing 10 produced in this embodiment has a concave structure on its side wall, and the forming assembly is used for forming this concave structure. The operation of the forming assembly is similar to that of the first slider 61 forming mechanism described above.

[0034] In addition, this utility model also includes a hot runner assembly, which is disposed between the upper mold base 3 and the top plate 12. During injection molding, the injection material enters the hot runner from the gate at the top plate 12. The hot runner continuously heats the injection material to ensure that the injection material can maintain the set temperature and flow into the molding cavity, thereby ensuring the molding quality of the product.

[0035] During the injection molding process, the injection material enters the hot runner assembly through the gate of the top plate 12. After being heated by the hot runner assembly, the injection material flows through the upper mold base 3 and the upper mold core 5, and enters the molding cavity, evenly filling the molding cavity. After curing, the drive assembly 64 pulls the slider to move outward, separating the upper mold and the lower mold. The first slider 61 molding block, the second molding block 72, and the third molding block 741 all separate from the product. At the same time, the angled ejector 91 ejects upward at an angle and separates from the product, achieving product demolding.
