Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] As attached Figure 1 As shown in the figure, it is a schematic diagram of the structure of the front shell of the ventilator in the embodiment of the utility model. It can be seen from the figure that the front shell of the ventilator is provided with a window viewing angle, and the window viewing angle is used to install the touch screen. However, since the window on the shell is limited by the mold ejection direction, the window viewing angle cannot be parallel to the surface of the front shell of the ventilator for installing the touch screen, resulting in the edge surface of the touch screen being not parallel to the window ejection direction of the front shell of the ventilator, resulting in defects such as uneven assembly gap, thereby affecting the appearance of the product. Figure 2 shown.

[0037] In view of the above technical problems, the utility model proposes a molding mold, including a rear mold, a front mold and an oblique withdrawal mechanism. The rear mold is provided with a convex mold, and the front mold is provided with a concave mold. An opening is provided in the concave mold, and the opening runs through the entire front mold from the front side of the front mold to the rear side of the front mold. The oblique withdrawal mechanism is arranged at the opening and extends into the concave mold. When the front mold and the rear mold are closed, the convex mold and part of the oblique withdrawal mechanism are located in the concave mold to form a cavity, and before the front mold and the rear mold are opened, the oblique withdrawal mechanism is withdrawn from the opening. The part of the oblique withdrawal mechanism located in the concave mold can mold the window viewing angle of the front shell of the ventilator, and make the surface of the molded front shell of the ventilator for installing the touch screen parallel to the window viewing angle, thereby solving the problem that the edge surface of the touch screen is not parallel to the window ejection direction of the front shell of the ventilator, and the defects such as uneven assembly gap appear.

[0038] The following is a detailed description of non-limiting implementations of the present invention in conjunction with the accompanying drawings.

[0039] As attached Figure 3 As shown in the figure, it is a schematic diagram of the overall structure of the forming mold in the embodiment of the utility model; Figure 4 As shown in FIG. 1 , it is a schematic diagram of the assembly structure of the forming mold in the embodiment of the utility model. Figure 3-4 It can be known that the forming mold includes a rear mold 1, a front mold 2 and an oblique drawing mechanism 3.

[0040] As attached Figure 5 As shown, the rear mold 1 is provided with a convex mold 11, and along the height direction, the convex mold 11 is gradually inclined toward the side of the rear mold 1 facing away from the front mold 2. The inclined design of the convex mold 11 is the main reason why the window on the shell in the prior art is limited by the mold ejection direction, so that the edge surface 1011 of the window viewing angle 101 cannot be parallel to the surface of the front shell 100 of the ventilator for installing the touch screen 103.

[0041] As attached Figure 6As shown, the front mold 2 is provided with a concave mold 21, and an opening 211 is provided in the concave mold 21. From the front side of the front mold 2 to the rear side of the front mold 2, the opening 211 runs through the entire front mold 2. The oblique withdrawal mechanism 3 is provided at the opening 211 and extends into the concave mold 21. When the front mold 2 and the rear mold 1 are closed, the convex mold 11 and part of the oblique withdrawal mechanism 3 are located in the concave mold 21 to form a cavity. The oblique withdrawal mechanism 3 is used to form a window viewing angle 101, and to make the surface of the molded ventilator front shell 100 for installing the touch screen 103 parallel to the window viewing angle. The window viewing angle is square, and the window viewing angle as a whole can be regarded as a surface, so that it is convenient to describe that the window viewing angle is roughly parallel to the surface of the ventilator front shell 100 for installing the touch screen 103. Before the front mold 2 and the rear mold 1 are opened, the oblique withdrawal mechanism 3 is withdrawn from the opening 211. The partial oblique extraction mechanism 3 located in the concave mold 21 can form a window viewing angle 101 of the front shell 100 of the ventilator, and the edge surface 1011 of the window viewing angle 101 is parallel to the direction of the surface of the vertical ventilator front shell 100 for installing the touch screen, thereby solving the problem that the edge surface 1011 of the touch screen 103 is not parallel to the window demolding direction of the front shell 100 of the ventilator, resulting in uneven assembly gap 102 and other defects.

[0042] In some embodiments, as shown in the attached Figure 7 As shown, the oblique drawer mechanism 3 includes a convex portion 31. When the front mold 2 and the rear mold 1 are closed, the convex portion 31 is located in the concave mold 21. The shape of the convex portion 31 is used to form the window viewing angle 101 of the breathing shell.

[0043] In some embodiments, the convex portion 31 includes a first surface 311 and a vertical edge 312 around the first surface 311, the vertical edge 312 is perpendicular to the first surface 311, and the vertical edge 312 is the edge of the edge surface 1011. The convex mold 11 includes a second surface 111. When the front mold 2 and the rear mold 1 are closed, the second surface 111 coincides with the first surface 311, and the vertical edge 312 is perpendicular to the second surface 111. Therefore, after the front shell 100 of the ventilator is demolded, the edge surface of the window viewing angle 101 is not parallel to the direction perpendicular to the front shell 100 of the ventilator, so that when the touch screen 103 is installed to the window viewing angle 101, there is no large assembly gap 102 between the touch screen 103 and the window viewing angle 101, as shown in the attached Figure 8 shown.

[0044] In some embodiments, the molding die is provided with a slider 4, which is disposed between the front mold 2 and the rear mold 1 and is located at the lower end of the molding die. When the front mold 2 and the rear mold 1 are closed, the slider 4 forms the wall of the cavity close to the side of the concave mold 21. The slider 4 is used to mold the support foot 104 of the front housing 100 of the ventilator. The support foot 104 is located at the lower end of the front housing 100 of the ventilator and is used to support the ventilator when the ventilator is in use. Since the support foot 104 protrudes downward from the front housing 100 of the ventilator, the slider 4 needs to be disposed at the lower end of the molding die.

[0045] In some embodiments, a first groove (not shown) is provided on the side of the slider 4 close to the concave mold 21, and when the front mold 2 and the rear mold 1 are closed, the first groove forms a part of the mold cavity. The shape of the cavity of the first groove is the same as the shape of the support foot 104 of the front housing 100 of the ventilator, and the first groove forms a part of the mold cavity so that the support foot 104 and the front housing 100 of the ventilator can be integrally formed.

[0046] In some embodiments, the front mold 2 is provided with a second groove 22, which is communicated with the concave mold 21 and is located at the lower end of the front mold 2; when the front mold 2 and the rear mold 1 are closed, the slider 4 is located in the second groove 22. In this way, the slider 4, as a separate component, can slide out of the second groove 22 before the rear mold 1 and the front mold 2 are opened.

[0047] In some embodiments, the molding die is provided with a first driving device, and the first driving device is connected to the slider 4. Before the front mold 2 and the rear mold 1 are opened, the first driving device drives the slider 4 to slide downward. The first driving device can automatically drive the slider 4 to move, thereby improving the automation degree of the molding die.

[0048] In some embodiments, the molding die is provided with a positioning structure, the positioning structure includes a positioning portion 51 and a positioning groove 52, the rear mold 1 is provided with one of the positioning portion 51 and the positioning groove 52, and the front mold 2 is provided with the other of the positioning portion 51 and the positioning groove 52. The positioning structure can assist the front mold 2 and the rear mold 1 in closing. When the positioning portion 51 and the positioning groove 52 are connected, it means that the positions of the front mold 2 and the rear mold 1 are correctly placed, so that they can be closed, so that the positions of the front mold 2 and the rear mold 1 after closing are not corresponding, thereby avoiding the deformation of the injection molded ventilator front housing 100.

[0049] In some embodiments, the molding die is provided with a second driving device, which is connected to the rear mold 1 and is used to drive the rear mold 1 to close or open with the front mold 2. The closing and opening of the rear mold 1 and the front mold 2 are driven by the second driving device, which can improve the automation degree of the molding die.

[0050] In some embodiments, the forming mold is provided with a third driving device, which is connected to the oblique withdrawal mechanism 3, and is used to extend the oblique withdrawal mechanism 3 into the opening 211 or withdraw it from the opening 211. Similarly, the oblique withdrawal mechanism 3 is extended into the opening 211 or withdrawn from the opening 211 by the third driving device, which can improve the automation degree of the forming mold.

[0051] In some embodiments, the molding die is provided with a second driving device, which is connected to the rear mold 1 and is used to drive the rear mold 1 to close or open the front mold 2. The molding die is provided with a third driving device, which is connected to the oblique withdrawal mechanism 3 and is used to extend the oblique withdrawal mechanism 3 into the opening 211 or withdraw it from the opening 211.

[0052] The utility model also provides a ventilator, the ventilator includes a front housing, and the front housing is injection molded by any of the molding molds in the above embodiments. The structure and beneficial effects of the ventilator front housing 100 molded by the molding mold have been described in detail in the above embodiments. Since the front housing is injection molded by the molding mold, the front housing includes the structure and beneficial effects of the ventilator front housing 100 molded by the molding mold, and for the sake of simplicity of the application text, it will not be repeated again.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
