Detailed Implementation

[0025] 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.

[0026] Reference Figure 1-7 This utility model provides a mold for a ventilator top cover, including a base plate 1, a mold foot 11 disposed on the base plate 1, a lower mold base 2 disposed on the mold foot 11, an upper mold base 3 disposed on the lower mold base 2, and a top plate 4 disposed on the upper mold base 3. The lower mold base 2 is provided with a lower mold 5, and the bottom surface of the upper mold base 3 is provided with an upper mold 6 that cooperates with the lower mold 5. The lower mold base 2 is provided with a plurality of side forming mechanisms 7, and the plurality of side forming mechanisms 7 are arranged around the lower mold 5. The upper mold 6, the lower mold 5, and the plurality of side forming mechanisms 7 surround and form a forming cavity for the top cover.

[0027] like Figure 5As shown, the top surface of the lower mold 5 is provided with a first forming boss 51 corresponding to the recess of the top cover plate. The first forming boss 51 is provided with a plurality of second forming bosses 52. The sidewall of the first forming boss 51 is provided with a plurality of first forming grooves 53. Each side of the inner wall of the recess of the top cover plate is provided with two protrusions, and the first forming grooves 53 match the protrusions. The top cover plate produced by the mold in this embodiment has two through holes; therefore, there are two second forming bosses 52 corresponding to the two through holes.

[0028] like Figure 7 As shown, the side forming mechanism 7 includes a guide assembly 71 disposed on the lower mold base 2, a movable seat 72 connected to the guide assembly 71, a side forming component 73 connected to the movable seat 72 on the side facing the lower mold 5, and a diagonal pull component 74 inserted into the movable seat 72. The upper end of the diagonal pull component 74 passes through the upper mold base 3 and connects to the top plate 4. The guide assembly 71 specifically includes two parallel guide blocks, and the movable seat 72 is connected between the two guide blocks. In this embodiment, four side forming mechanisms 7 are provided. The first forming boss 51 is generally rectangular, and the four side forming mechanisms 7 correspond to the four sides of the first forming boss 51, respectively. Specifically, the upper mold 6, the lower mold 5, and the forming components of the four side forming mechanisms 7 surround and constitute the forming cavity of the top cover plate.

[0029] The lower end of the inclined pull member 74 is bent outward toward the lower mold base 2 to form an inclined portion 741. The movable base 72 is provided with an insertion interface 721 that mates with the inclined portion 741. Therefore, when the movable base 72 moves horizontally, the inner wall of the insertion interface 721 pushes the inclined pull member 74, causing it to move vertically, thereby realizing the mold opening and closing action. Alternatively, a slot matching the inclined portion 741 can also be provided on the lower mold base 2. When the mold is closed, the inclined portion 741 inserts into the slot, ensuring the accuracy and stability of mold closing.

[0030] like Figure 6 As shown, the bottom surface of the upper mold 6 is provided with a third forming boss 61. The third forming boss 61 is provided with a plurality of second forming grooves 62 for forming the protrusions of the top cover plate and two fourth forming bosses 63 that cooperate with the first forming boss 51. The two fourth forming bosses 63 are respectively located on both sides of the first forming boss 51. In this embodiment, the top cover plate has four protrusions, therefore, four second forming grooves 62 are provided corresponding to the protrusions of the top cover plate.

[0031] The third forming boss 61 has recessed portions 64 on both opposite sides that mate with the snap-fit ​​structure of the top cover plate, and the recessed portions 64 can accommodate the snap-fit ​​structure. The top surface of the third forming boss 61 has a fifth forming boss 65 that mates with the second forming boss 52.

[0032] The top surface of the third molding boss 61 is provided with a slag discharge groove 66 along its edge. During the injection molding process, a raw material volume greater than the product volume is injected to ensure that the injection material can fill the entire molding cavity and ensure the complete molding of the product. The slag discharge groove 66 can accommodate excess injection material during the injection molding process. In this embodiment, the slag discharge groove 66 is generally arranged in a ring along the top edge of the third molding boss 61, thereby facilitating the flow of injection material from multiple directions to the slag discharge groove 66.

[0033] like Figure 6 As shown, the ventilator top cover mold also includes a hot runner assembly 8, and the upper mold base 3 is provided with a recess 31 for accommodating the hot runner assembly 8. The hot runner assembly 8 specifically includes a hot runner plate and a heating element, which is heated by an external power source (not shown in the figure) to ensure that the injection molding material can be injected into the molding cavity at a set temperature.

[0034] The ventilator top cover mold also includes a drive assembly 9, which includes a drive seat 91 connected to the upper mold base 3 and a drive component 92 connected to the drive seat 91. The drive component 92 is connected to one of the side forming mechanisms 7. The drive component 92 can be a hydraulic cylinder. During the mold opening process, when the piston rod of the hydraulic rod retracts, it drives the moving seat 72 away from the lower mold 5, thereby pushing the inclined pull member 74 upward to realize the mold opening.

[0035] The top cover plate produced in this embodiment has two parts, including part a and part b. Part a is the main body, and part b is a frame with protrusions connected to the back of part a. The whole is manufactured by a two-color injection molding process. The mold in this embodiment is used for molding part b. During the production process, the lower mold 5 first cooperates with another upper mold 6 to complete the molding of part a. Then, the other upper mold 6 separates from the lower mold 5, and the lower mold 5 then cooperates with the upper mold 6 in this embodiment to complete the molding of part b. During the injection molding process, the injection molding material enters the mold from the gate of the top plate 4, passes through the hot runner assembly 8, and is injected into the molding cavity formed by the upper mold 6, the lower mold 5, and the side molding mechanism 7.

[0036] The lower mold 5 of this utility model, together with the upper mold 6 and the side forming mechanism 7, forms the forming cavity of the top cover plate. The lower mold 5 is provided with a first forming boss 51, a second forming boss 52 and a forming groove corresponding to the concave platform of the top cover plate. The third forming boss 61 is provided with a plurality of second forming grooves 62 for forming the protrusion of the top cover plate. After the injection molding material enters from the gate, it can be quickly injected into the forming cavity and evenly fill the entire forming cavity, realizing the rapid forming of the top cover plate of the ventilator, which is convenient for mass production.
