Technical Field

The utility model relates to an automobile glass subassembly, concretely relates to inserts for automobile glass subassembly.

Background

Some automotive glass assemblies require the insert to be injection molded simultaneously with the glass substrate. These inserts may be used for decoration or have other specific structural functions, for example as mounting bases.

In some injection molding processes, it is necessary to first secure the insert to the upper mold. In this case, it is necessary to ensure that the insert is firmly connected to the upper mold before the mold is closed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an inserts for door window glass subassembly, it can stabilize and be connected to the mould of going up.

According to the utility model discloses, an inserts for car glass subassembly is suitable for and installs in injection molding process and goes up the mould install on the body of inserts with the position that the pore pair of going up the mould is equipped with at least one joint structure, the biggest radial dimension of joint structure is greater than corresponding the open-ended diameter in the hole of last mould, and when joint structure received sufficient pressure and takes place elastic deformation, the biggest radial dimension is less than the diameter. Therefore, when the clamping structure is elastically deformed, the radial size of the clamping structure is reduced so as to be inserted into the hole of the upper die, and after the clamping structure is inserted, the elastic deformation acts to generate acting force so that the clamping structure can be kept in the hole.

Furthermore, the clamping structure is provided with an upper inclined plane, an outer plane and a lower inclined plane on the radial outward side, and the upper inclined plane, the outer plane and the lower inclined plane are sequentially connected in the direction of the central axis.

The maximum radial dimension is the diameter of a circumcircle of a geometric figure formed by projection of the clamping structure on a radial section. The circumscribed circle takes the central axis as the center of a circle and takes the maximum distance between the outer side of the clamping structure and the central axis as the radius. Thus, the maximum radial dimension may be twice the maximum distance of the outer planar surface from the central axis.

The upper bevel plays a guiding role in the insertion process, and the insertion is convenient.

Furthermore, in the case where the inner diameter of the hole of the upper die is the same as the diameter of the opening thereof, after insertion, the outer plane abuts against the inner wall of the hole by the urging force generated by the elastic deformation, and the insert and the upper die are kept connected by the frictional force generated thereby.

Or, in the case that the opening of the hole has an inner edge, that is, the inner diameter of the hole is different from the diameter of the opening, further, if the inner diameter of the hole is smaller than the maximum radial dimension of the clamping structure, the outer side plane can similarly abut against the inner wall of the hole, and at this time, the insert and the upper die can be kept connected by means of the friction force of the outer side plane and/or the abutting of the lower inclined surface against the inner edge. And if the inner diameter of the hole is larger than the maximum radial dimension of the clamping structure, the clamping structure is elastically deformed and restored after being installed, and the insert and the upper die can be kept connected only by means of the fact that the lower inclined surface abuts against the inner edge. In the above case, the lower inclined surface can also abut against the inner edge of the hole after the clamping structure is mounted. The lower slope may act as a guide surface during demolding. The elastic deformation of the clamping structure can be elastic deformation of materials or elastic deformation of the structure.

Further, the joint structure includes at least one elasticity locking portion, elasticity locking portion is in the central axis's of hole direction extend and form joint portion, the upper portion inclined plane the outside plane with the lower part inclined plane sets gradually the outside of joint portion.

The elastic locking part can be elastically deformed through the structure so that the radial size of the clamping structure can be changed. When the elastic locking part is elastically deformed, the clamping part is constructed to move at least in the radial direction.

Further, the clamping structure comprises at least two elastic locking parts which are identical in structure and are symmetrically arranged about the central axis.

Further, the clamping structure further comprises a cylinder connected with the body of the insert, wherein the elastic locking part is connected to the side face of the cylinder. Wherein the upper end of the cylinder is reduced in size in radial cross-section to form a tapered or narrowed upper end. The elastic locking part is connected to the upper part of the side face of the column body, or the elastic locking part is connected to the lower part of the side face of the column body. Wherein, the cylinder passes through the base with the body coupling of inserts. Wherein the cross section of the cylinder is configured to be circular, oval, rectangular or other polygonal shape. Wherein the column is constructed in a hollow structure or a solid structure. Wherein the cylinder and the elastic locking part are integrally formed.

Or the elastic locking part is directly connected with the body of the insert, or is connected with the body of the insert through a base.

In addition, the clamping structure can be integrally formed with the body of the insert, or the clamping structure is connected with the body of the insert in a separable mode.

The utility model discloses in, when installing this inserts and going up the mould, the joint structure inserts in the hole of mould. In the inserting process, the clamping part of the elastic locking part is extruded to move towards the central axis direction of the hole.

Detailed Description

Specific embodiments of the present invention are described below with reference to the accompanying drawings, wherein the specific details are for the purpose of illustration only and are not to be construed as limitations of the present invention.

According to the utility model, as shown in fig. 1, the insert is used for being connected with a glass substrate (not shown) in a mode of injection molding edge covering. Before the hemming process, the insert is fixed below an upper die (not shown) and can be separated from the upper die after the hemming process is completed. For this purpose, a snap-in structure 100 is provided on the body 10 of the insert, in a position corresponding to a hole (not shown) of the upper die. In one example, the snap structure 100 is integrally formed with the insert body 10. Alternatively, in another example, the latch structure 100 may be detachably connected to the insert body 10, such as by bonding or welding, so long as the strength of the connection is sufficient to secure the insert to the upper mold. The clip structure 100 may be attached directly to the insert body 10 or attached to the insert body 10 via the base 20.

In addition, the position, structure, the function of the hole of going up the mould can be different, the technical scheme of the utility model need not carry out the special limitation to these characteristics. Those skilled in the art will be able to determine which hole or holes on the insert to place the snap features in a location corresponding to based on the structure, function, and process specifications of the holes.

In this application, the terms "upper" and "lower" indicating orientation are relative to each other in the upper and lower orientation shown in the drawings. And, the term "radial" indicating orientation means a radial direction of the hole of the upper die. The term "bottom" or "bottom" in reference to orientation refers to an orientation proximate to the insert, i.e., the lower portion of the illustrated structure. "Top" or "top" indicating orientation refers to an orientation away from the insert, i.e., the upper portion of the illustrated structure.

The directional terms "inner" or "inwardly" refer to a direction toward the central axis of the bore of the upper die, while the directional terms "outer" or "outwardly" refer to a direction away from the central axis.

In addition, the central axis of the bore of the upper die is shown in FIGS. 2-6, which illustrate the relative positional relationship between the snap structure and the central axis when the snap structure is inserted into the bore of the upper die.

The snap structure 100 is at least partially elastically deformable. Therefore, when the clamping structure 100 is not elastically deformed, the maximum radial dimension of the clamping structure 100 is larger than the opening diameter of the corresponding hole of the upper die, and when the clamping structure 100 is elastically deformed, the maximum radial dimension is smaller than the opening diameter of the hole. The maximum radial dimension is the diameter of the circumscribed circle of the geometric figure formed by the projection of the clamping structure 100 on a radial cross section.

The outer side of the clamping structure is provided with an upper inclined plane, an outer plane and a lower inclined plane which are sequentially connected. In this case, the diameter of the aforesaid circumscribed circle is twice the maximum distance of the outer flat surface from the central axis. Namely, the circumscribed circle is a circle which takes the central axis as the center of a circle and takes the maximum distance between the outer plane and the central axis as the radius.

The clamping structure is elastically deformed under the action of an acting force, so that at least the radial size of the clamping structure is reduced, and the clamping structure can be inserted into a hole of the upper die. In one aspect, the outer plane abuts against the inner wall of the hole with the aid of an acting force generated by elastic deformation after the clamping structure is inserted into the hole of the upper die.

Alternatively, when the hole in the upper mold has an inner edge (not shown), the lower bevel may abut against the inner edge of the hole after the snap-fit structure is installed, thereby ensuring a stable installation. And the lower slope may act as a guide surface at the time of demolding.

In the following embodiments, various structural forms of the snap structure are described.

Referring to fig. 2 and 3, one embodiment of the snap-fit structure is further described. The latch structure 100 includes a cylinder 110 and a resilient latch 120 disposed on a side of the cylinder.

In this embodiment, the cylinder 110 is fixed to the body 10 of the insert by means of the base 20. However, as previously mentioned, the post 110 may also be fixed directly to the body 10 of the insert. The upper end of the cylinder 110 is relatively reduced in size to form a tapered structure to facilitate insertion into the hole of the upper mold.

In fig. 2 and 3, the cylinder 110 is of hollow construction, however, in other embodiments, the cylinder may be of solid construction. Similarly, in this embodiment, the cross-section of the cylinder 110 is circular, however, one skilled in the art will appreciate that other cross-sections may be used, such as rectangular, elliptical, or other regular or irregular shapes.

In the present embodiment, the cylinder 110 is configured to be coaxial with the hole of the upper die, i.e. the axis of the cylinder 110 coincides with the central axis 30 of the hole. The two spring latching sections 120 are designed to be arranged axially symmetrically, i.e. symmetrically with respect to the central axis 30 in this exemplary embodiment, and each project at least partially over the cylinder 110.

In this embodiment, the elastic locking portion 120 is configured to be coupled to an upper side of the cylinder 110. However, those skilled in the art will recognize that in other examples, the resilient locking portion 120 may be configured to engage the lower side of the post 110.

In this embodiment, the resilient locking portion 120 is integrally formed with the cylinder 110.

The elastic locking portion 120 extends downward from the connection with the cylinder to form a clamping portion 130. The catching portion 130 is configured to be movable at least in a radial direction. The size of the radial section of the catching portion 130 increases in the extending direction so that the outer side of the catching portion 130 protrudes in the radial direction from the cylinder 110. The catching portion 130 is provided at an outer side thereof with an upper inclined surface 132, an outer flat surface 134 and a lower inclined surface 136 which are connected in series in a direction along the central axis 30.

In this embodiment, the elastic deformation of the clamping structure is an elastic deformation of the elastic locking portion 120 in at least a radial direction under an external force, and thus causes the clamping portion 130 to move in at least a radial direction.

In this embodiment, the maximum radial dimension of the snap fit arrangement is twice the maximum distance of the outer flat surface 134 of the resilient latch portion from the central axis 30 when the resilient latch portion 120 is not subjected to an external force. In the embodiment shown in fig. 2 and 3, the maximum radial dimension is the distance between the two outer flat surfaces 134.

And when the elastic locking part is elastically deformed under the action of sufficient pressure, the maximum radial dimension of the clamping structure is smaller than the diameter of the hole.

When the insert is mounted to the upper die, the snap structure 100 is inserted into the hole of the upper die. Since the maximum radial dimension at the snap-in portion 130 is greater than the diameter of the bore, the upper ramp 132 acts as a guide surface that is first compressed by the bore. The upper ramp 132 translates a portion of the pressure into a radially inward force, i.e., a force directed toward the central axis 30. The resilient locking portion 120 is displaced toward the central axis 30 by this radially inward force. The maximum radial dimension at the snap-in portion 130 is less than the inner diameter of the hole as the snap-in structure is fully inserted into the hole of the upper die. After installation, the outer flat surface 134 of the snap-fit portion 130 abuts the inner wall of the hole and frictionally holds the insert in place.

Fig. 4 and 5 show an exemplary embodiment of a clamping arrangement in another embodiment.

In this embodiment, the snap structure 200 (e.g., the snap structure 100 of fig. 2 and 3) similarly has a cylindrical body 210 and a resilient latch portion 220, wherein the two resilient latch portions 220 are identically constructed and symmetrically arranged. The cylinder 210 is configured to be coaxial with the hole of the upper die, i.e. the axis of the cylinder 210 coincides with the central axis 30 of the hole.

The elastic locking portion 220 is fixedly connected to the upper portion of the side surface of the column 210, and extends downward and outward to form a locking portion 230. That is, the elastic locking portion 220 extends toward the insert body 10 substantially along the central axis 30 while deviating in a direction away from the central axis 30. In another variation of this structure, the elastic locking portion can be connected to the lower side of the column 210 and extend obliquely upward and outward to form the engaging portion. The catching portion 230 is configured to be movable at least in a radial direction.

The elastic deformation of the latch structure 200 is that the elastic locking portion 220 is elastically deformed at least in the radial direction under the action of an external force, and thus the latch portion 230 is caused to move at least in the radial direction.

In this embodiment, the catching portion 230 is constructed in a plate-like structure and has an upper slope 232, an outer flat surface 234, and a lower slope 236 which are connected in this order in the central axis direction of the hole of the upper die.

In this embodiment, the cylinder 210 is configured as a sheet-like structure having a rectangular cross-section (i.e., a radial cross-section) with a large aspect ratio. And the upper end is similarly shrunk in size to form a narrowed upper end. In this embodiment, the cylinder 210 is connected to the body 10 of the insert by means of the base 20. Otherwise, the cylinder 210 can also be directly connected to the body 10 of the insert. The lower portion of the column 210 is configured with a support structure 240.

In this embodiment, the maximum radial dimension of the snap-fit structure is the distance between the outer flat surfaces 234, i.e., twice the maximum distance between the outer flat surfaces 234 and the central axis 30. When the elastic locking portion 220 is elastically deformed by a sufficient pressure, the maximum radial dimension of the latch structure 200 is smaller than the diameter of the hole.

Similarly, when the upper mold is inserted into the hole, the inclined portion (i.e., the upper inclined surface 232) of the engaging portion 230 serves as a guide inclined surface, and a part of the force applied from the inner wall of the hole is converted into a radially inward force, so that the elastic locking portion 220 is elastically deformed. After insertion, the outer flat surfaces 234 of the snap-in portions 230 abut against the inner wall of the hole of the upper die, and the insert is held on the upper die by the frictional force generated by the elastic force.

Fig. 6 shows an exemplary embodiment of a clamping arrangement in the form of a further embodiment.

In this embodiment, the snap structure 300 (e.g., the snap structure 100 of fig. 2 and 3) includes only the resilient latch portion 320, which is secured to the body 10 of the insert. The two resilient latching portions 320 are identically constructed and symmetrically arranged.

The elastic locking portion 320 is fixed to the body 10 of the insert by the base 20. Alternatively, in another example, the resilient locking portion 320 may be directly fixed to the body 10 of the insert.

The resilient latch portion 320 is configured as a tab, however, other shapes may be used, such as the configurations described in connection with fig. 2-5. Also, the base 20 may be constructed as shown in FIGS. 2-5 or otherwise as appropriate for the particular application.

In the embodiment shown in fig. 6, the resilient latch portion 320 extends upwardly to form a snap-fit portion 330. The elastic locking portion 320 may extend obliquely outward.

The snap-in portion 330 includes an upper ramp 332, an outer flat surface 334, and a lower ramp 336. The catching portion 330 is configured to be movable at least in the radial direction. In this embodiment, the radial sectional dimension of the catching part 330 is increased in the extending direction so as to form a protruding part at the outer side. In this embodiment, the maximum radial dimension of the snap structure 300 is the distance between the two outer flat surfaces 334, i.e., twice the maximum distance of the outer flat surfaces 334 from the central axis 30.

In this embodiment, similarly, the elastic deformation of the clamping structure is an elastic deformation of the elastic locking portion in at least a radial direction under an external force, thereby causing the clamping portion 330 to move in at least a radial direction. Similarly, when the upper mold is inserted into the hole of the upper mold, the upper inclined surface 332 of the engaging portion 330 serves as a guiding inclined surface, and a part of the force applied from the inner wall of the hole is converted into a radially inward force, so that the elastic locking portion 320 is elastically deformed. After insertion, the outer flat surface 334 of the snap-in portion 330 abuts against the inner wall of the hole of the upper die, and the insert is held on the upper die by the frictional force generated by the elastic force.

In another embodiment, the elastic deformation of the snap-fit structure is achieved by elastic deformation of the material used, rather than by structural elastic deformation as in the embodiment shown in fig. 2-6. For example, the snap-fit structure is at least partially made of an elastic material. Wherein, the clamping structure can be partially or completely elastically deformed.

For example, the snap-in structure may comprise an elastic latching portion provided on the outside. The elastic locking part can be made of elastic materials and can elastically contract and deform under the action of external force to reduce the radial size of the clamping structure. In this case, the elastic locking portion may still be provided with an upper inclined surface, an outer flat surface, and a lower inclined surface.

In this embodiment, too, the maximum radial dimension is twice the distance of the outer plane of the spring latching portion from the central axis.

Similarly, when the snap-fit structure is inserted into the bore of the upper die, the upper ramp acts as a guide surface to facilitate insertion. A part of acting force from the inner wall of the hole, which is applied to the upper inclined surface, is converted into radially inward acting force, so that the elastic locking part is elastically deformed. After insertion, the outer flat surface abuts against the inner wall of the hole of the upper die, and the insert is held on the upper die by the frictional force generated by the elastic force.

Although in the illustrated embodiments, two snap features are provided, in other embodiments, one snap feature may be provided, or more than two snap features may be provided. One skilled in the art can determine the number of clamping structures required depending on the particular application, such as the configuration of the top mold, the configuration of the insert, the weight of the insert, and the like.

Also, as previously described, the resilient latching portions are symmetrically disposed, however, in other embodiments, they may be asymmetrically disposed. Also, the shape of the resilient latching portion may be determined by the particular application, such as the shape of its own cross-section.

Whether symmetrical or not, the maximum radial dimension of the snap-fit structure may be the diameter of a circumscribed circle of a geometric figure formed by a projection of the snap-fit structure on a radial cross section. Further, the circumscribed circle may be a circle having the center axis as a center and the maximum distance between the outer plane and the center axis as a radius, and thus the maximum radial dimension is twice the maximum distance between the outer plane and the center axis.

The magnitude of the generated friction force can be adjusted by selecting the material and the size of the elastic locking part. For example, the material and size of the elastic locking portion may be determined by determining the magnitude of the required frictional force from the weight of the insert, and further determining the pressure of the static friction from the coefficient of friction of the inner wall of the hole of the upper die. For example, when greater friction is desired, the size, e.g., width and/or thickness, of the resilient latch portion may be increased to enable it to generate a greater resilient force.

It will thus be appreciated by those skilled in the art that the present invention is not limited to the particular details set forth in the above-described embodiments, but may be varied within the scope of the claims.
