Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It should be noted that, if directional indications (such as up, down, left, right, front, and rear … …) are included in the embodiments of the present invention, the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed. In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

As shown in fig. 1 and 2, one embodiment of the present invention provides a bottom cover structure of a mouse, which includes a cover body 1 and a foot pad 2. As shown in fig. 3, a connecting portion 21 is protruded at one side of the footpad 2, and preferably, the connecting portion 21 is integrally formed on the footpad 2. The connection portion 21 may have a rod shape. The end of the connecting portion 21 facing away from the footpad 2 may be provided with a hook portion 22, and similarly, the hook portion 22 may be integrally formed on the connecting portion 21. One side of the cover body 1 is provided with a hanging groove 101, and the bottom of the hanging groove 101 is provided with a through hole 105 penetrating to the other side of the cover body 1. As shown in fig. 4, the hook 22 is hooked on the bottom surface of the hanging groove 101, and the foot pad 2 is fastened to the side of the cover 1 facing away from the hanging groove 101 via the connecting portion 21.

In the above example, since the hook 22 does not participate in friction, and is not aged as easily as glue, its structure is stable. Through the hook of the hook part 22, the foot pad 2 can be tightly clamped on the cover body 1, so that the connection stability between the foot pad 2 and the cover body 1 is good, and the foot pad is not easy to loose.

The aforementioned connection portion 21 may have a cross-sectional profile consistent with that of the via 105, and "consistent" herein means that the shape and the size of the cross-sectional profiles of the connection portion 21 and the via 105 are the same, and of course, in order to assemble the connection portion 21 in the via 105, there is a certain deviation between the two, which is a prior art and will not be described herein. In this example, the connection portion 21 is designed to have a cross-sectional profile corresponding to the through hole 105, mainly to prevent the connection portion 21 from being deformed, so that the structure in which the connection portion 21 is engaged with the hook portion 22 is distinguished from the structure of the conventional elastically deformable buckle. The connecting portion 21 cannot be deformed, so that the hook portion 22 cannot be withdrawn from the through hole 105, and the foot pad 2 is tightly fastened to the cover 1, and cannot be released from the cover 1.

In order to prevent the release of the footpad 2 from the cover 1, the present invention provides, in addition to the above-described arrangement of the connecting portion 21 to a cross-sectional profile conforming to the via 105, the following embodiments: as shown in fig. 3, the aforementioned hook 22 may be an annular flange provided at one end of the connecting portion 21. The annular flange is hooked on the bottom surface of the hooking groove 101 in the circumferential direction. Specifically, the hanging groove 101 may be a groove that expands outward in the circumferential direction with respect to one end of the via hole 105, and the annular flanges are each in contact with the bottom surface of the hanging groove 101 in the circumferential direction. In this way, the annular flange cannot be withdrawn from the through hole 105, so that the foot pad 2 can be tightly clamped on the cover body 1 and cannot be loosened from the cover body 1.

As shown in fig. 4, the aforementioned annular flange may have a cross-sectional profile corresponding to the hanging groove 101, that is, the cross-sectional profile of both are identical in shape and size, so that after the annular flange is assembled in the hanging groove 101, no gap exists between the annular flange and the inner wall of the hanging groove 101, and the appearance is more attractive.

Embodiments of the present invention also provide a mouse, which may include any of the above-described mouse bottom cover structures. Due to the fact that the mouse is provided with the bottom cover structure of the mouse, connection stability between the foot pad 2 and the cover body 1 is good, and the mouse is not easy to loose.

As shown in fig. 5, the present invention further provides a two-shot injection mold for processing any one of the above-mentioned bottom cover structures of the mouse. The double-shot injection mold comprises a first female mold 3, a second female mold 4 and two male molds 5. Both male molds 5 can be clamped with the first female mold 3 and the second female mold 4. When the first female mold 3 or the second female mold 4 is clamped with either male mold 5, an injection cavity is formed therebetween to mold an injection molded article. As shown in fig. 6, the first female mold 3 has a first cavity 31, and the first cavity 31 is used for molding one side of the cover 1 facing away from the hanging groove 101. The first master model 3 has a master template on which the first cavity 31 may be directly provided. Of course, for convenience of maintenance, a cavity may be provided on the master plate of the first master mold 3, and the first cavity 31 may be provided on the cavity of the first master mold 3. As shown in fig. 7, a first insert 32 is provided in the first cavity 31, and the first insert 32 is used to mold the through hole 105 in the lid 1. The first insert 32 has a shape consistent with the via 105, and in one specific application example, the first insert 32 is rod-shaped and fixed in the first cavity 31, for example, the first insert 32 may be integrally formed on an inner wall of the first cavity 31.

As shown in fig. 6, the aforementioned second master model 4 has a second cavity 41, and the second cavity 41 is used to mold the side of the footpad 2 facing away from the hook portion 22. Similarly, the second master mold 4 also has a master mold plate, and the second cavity 41 may be directly provided on the master mold plate. For convenience of maintenance, a cavity may be provided on the master plate of the second master mold 4, and the second cavity 41 may be provided on the cavity of the second master mold 4.

The two male molds 5 are provided with cores, and the cores are used for forming one side, close to the hanging groove 101, of the cover body 1. As shown in fig. 9, each core is provided with a movable insert 6, and each movable insert 6 can move to a first position and a second position relative to the corresponding core, and the movable insert 6 is used for forming the hanging groove 101 in cooperation with the first cavity 31 when moving to the first position, and forming the hook 22 in cooperation with the second cavity 41 when moving to the second position.

Specifically, when the bicolor injection mold is used, the first female mold 3 is clamped with one male mold 5, the movable insert 6 on the male mold 5 moves to the first position at the moment, the cover body 1 can be formed between the first female mold 3 and the male mold 5 during injection molding, and the formed cover body 1 is remained on the male mold 5 after the mold is opened. Then the injection molding machine drives the male mold 5 to move to be matched with the second female mold 4, at the moment, the movable insert 6 on the male mold 5 moves to the second position, and the foot pad 2 and the hook part 22 can be molded on the cover body 1 during injection molding.

In the above example, the first female mold 3 and the second female mold 4 of the two-color injection mold are respectively matched with the male mold 5 for injection molding, and the foot pad 2 and the connecting portion 21 and the hook portion 22 thereon can be molded on the cover 1, so that the foot pad 2 cannot be released from the cover 1, and the connection stability of the foot pad 2 and the cover 1 is improved.

In order to facilitate the adjustment of the position of the movable insert 6, a transmission mechanism may be provided on each male mold 5. The transmission mechanism is used for driving the movable insert 6 to move to the first position by the first female die 3 when the male die 5 and the first female die 3 are in die assembly, and driving the movable insert 6 to move to the second position by the second female die 4 when the male die 5 and the second female die 4 are in die assembly. In this example, the power sources for moving the movable insert 6 are the first female die 3 and the second female die 4 respectively, and no additional power source is needed, so that the cost is saved, and the movable insert can be automatically pushed to the first position or the second position during die assembly, and the control is convenient.

In order to realize the function of the aforementioned transmission mechanism, as shown in fig. 10, the aforementioned transmission mechanism may include a connection plate 9, and the connection plate 9 is a movable plate and is used for fixing the aforementioned movable insert 6. Wherein, the transmission mechanism drives the movable insert 6 to move to the first position and the second position through the connecting plate 9. In this example, by providing the connection plate 9, there is an effect of facilitating the installation of the movable insert 6.

In a specific application example, as shown in fig. 10, the aforementioned movable insert 6 may have a rod shape, and the head of the movable insert 6 has a shape conforming to the hanging groove 101. The bottom of the movable insert 6 is provided with a hanging table. The aforementioned connection plate 9 includes a first connection plate 91 and a second connection plate 92 which are laminated and fixed. The movable insert 6 passes through the first connecting plate 91, the bottom of the movable insert is hung on the first connecting plate 91, and the second connecting plate 92 is stacked on one side of the first connecting plate 91 and abuts against the bottom of the movable insert 6 so as to fix the movable insert 6 on the first connecting plate 91.

In order to achieve the function of driving the movable insert 6 to move to the first position when the first female mold 3 is closed, as shown in fig. 10, the transmission mechanism may further include a connection block 10. The connection block 10 has opposite first 103 and second 104 ends. The connection block 10 also has a middle portion located between the two ends. The middle part is rotatably connected to the male mould 5 via a first pivot 13, so that the connecting block 10 forms a lever structure. The specific installation of the first rotating shaft 13 is a prior art, and will not be described herein. The first end 103 is used for being pressed by the first female die 3 to drive the second end 104 to move so as to push the connecting plate 9 to move the movable insert 6 to the first position. In this example, the connecting block 10 is configured as a lever structure, so that the movable insert 6 can be moved to the first position when the first female mold 3 is closed, mainly for facilitating the transmission of force.

The first end 103 of the connection block 10 may be directly pressed when the first female mold 3 is closed, or the first end 103 of the connection block 10 may be indirectly pressed. The first end 103 of the connecting block 10 is indirectly pressed against the first female mold 3 when the first female mold is closed, and as shown in fig. 10, the first end 103 may be provided with a pressing rod 7, and the first end 103 is pressed against the first female mold 3 through the other end of the pressing rod 7 when the first female mold is closed. The length of the compression bar 7 is not too long, and the compression bar 7 is easy to deform when being pressed if the length of the compression bar 7 is too long. In a specific application example, a push rod 8 may be disposed on the first female mold 3, and the first female mold 3 presses the pressing rod 7 through the push rod 8, so as to drive the first end 103 of the connecting block 10 to move. In this example, the length of the plunger 7 is shortened due to the provision of the plunger 8, so that the structure of the plunger 7 is more stable.

Since the connecting block 10 is of a lever structure, if the pressing rod 7 is fixed on the connecting rod, the pressing plate 7 inevitably tilts when being pressed, so that the pressing rod 7 is unevenly stressed to be damaged. Therefore, as shown in fig. 10, it is preferable that both the first end 103 and the end of the pressing rod 7 can be connected by the second rotating shaft 14, and the second rotating shaft 14 is parallel to the first rotating shaft 13. Thus, the pressing rod 7 can rotate relative to the first end 103 of the connecting block 10 when being pressed, so as to keep the axis direction parallel to the stress direction.

In order to achieve the effect that one end of the aforementioned pressing rod 7 is connected to the first end 103 through the second rotating shaft 14, in a specific application example, as shown in fig. 11, one end of the aforementioned pressing rod 7 is provided with a base 11. The base 11 is provided with an arc-shaped groove 111, the first end 103 of the connecting block 10 is provided with an arc-shaped protrusion 102, and the arc-shaped protrusion 102 is inserted into the arc-shaped groove 111, so that the pressing rod 7 can rotate relative to the first end 103 of the connecting block 10. The aforementioned second rotating shaft 14 passes through two sides of the first end 103 of the connecting block 10, one side of the base 11 is fixed with the first mounting block 17, the other side is fixed with the second mounting block 18, and both the first mounting block 17 and the second mounting block 18 can be detachably fixed on the base 11 by screws or the like. The first installation block 17 is sleeved at one end of the second rotating shaft 14, and the second installation block 18 is sleeved at the other end of the second rotating shaft 14. Thus, the first and second mounting blocks 17 and 18 provide an effect of preventing the base 11 from being detached from the first end 103 of the connection block 10.

Because the connecting block 10 is in a lever structure, similarly, after the first end 103 of the connecting block 10 is stressed, if the second end 104 of the connecting block 10 directly abuts against the connecting plate 9, the second end 104 of the connecting block 10 can incline in the process of pushing the connecting plate 9, so that the stress on the second end 104 of the connecting block 10 is uneven, and the connecting block is easy to damage. Therefore, as shown in fig. 10, the second end 104 of the connecting block 10 may be connected to the connecting member 12 through a third rotating shaft 15, and the third rotating shaft 15 is parallel to the first rotating shaft 13. The second end 104 pushes the aforementioned web 9 through the connection 12. In this way, the connecting piece 12 can rotate in the process of pushing the connecting plate 9, so that the force application direction of the connecting plate 9 is kept unchanged.

In order to achieve the aforementioned connection effect of the connecting member 12 and the second end 104 through the third rotation shaft 15, in a specific application example, as shown in fig. 11, the connecting member 12 may have a structure consistent with the aforementioned base 11, and similarly, the second end 104 of the connecting block 10 may also have a structure consistent with the first end 103, so that the structure of the connecting member 12 and the second end 104 connected through the third rotation shaft 15 may refer to the related description of the connection between the base 11 and the first end 103 through the second rotation shaft 14, which is not repeated herein.

In order to realize the function of driving the movable insert 6 to move to the second position when the second female mold 4 is closed, as shown in fig. 5, each male mold 5 includes a male mold plate 51 and an ejector plate 52. The aforementioned cores are provided on the male mold plate 51. Preferably, the male mold plate 51 is provided with a male mold core, and the core is disposed on the male mold core. The aforementioned connection plate 9 is provided between the male die plate 51 and the ejector plate 52. An elastic element 16 is arranged between the male mould plate 51 and the connecting plate 9. The elastic member 16 may be a spring or the like. A guide post can be connected between the male die plate 51 and the ejector plate 52, and the guide post passes through the connecting plate 9, and the elastic piece 16 is sleeved on the guide post. The male mold plate 51 is pressed by the second female mold 4 and drives the connecting plate 9 to move through the elastic member 16, so that the movable insert 6 moves to the second position. In this example, the elastic member 16 has a buffering function, so that the impact applied to the connection plate 9 can be relieved, and the service life of the connection plate 9 is prolonged.

In a specific application example, as shown in fig. 10, when the dual color injection mold of the present invention includes the connection block 10, the connection block 10 may be connected to the ejector plate 52 between the connection plate 9 and the ejector plate 52, thus achieving the installation of the connection block 10.
