[0002] Due to the fact that automobile sunroofs on the market are becoming larger and larger, production moulds are also designed to be larger and larger to adapt to them. At present, the fixing modes of the mould and the mould frame are screw fixing and magnetic attraction respectively. Due to the increase of the mould, the weight also increases, and the mould has the risk of falling off the mould plate during the rotating movement of the mould frame.

[0003] The contents in the background art part are only known to the inventor and do not necessarily represent the prior art in the field. UTILITY MODEL CONTENTS

[0004] In view of the above problems, the utility model provides a mould anti-falling device for fixing a mould on a mould plate, comprising:

[0005] at least two positioning pins installed on the mould plate, which cooperate with positioning holes on the mould; and

[0006] a locking device installed on the mould plate;

[0007] The locking device comprises:

[0008] a base installed on the mould plate; and

[0009] a locking member arranged on the base and movably connected with the base, used for controlling the mould on the positioning pins.

[0010] Further, the locking member can form an intersection area with the mould, and the mould is locked through the intersection area, so as to prevent it from falling off the positioning pins. The minimum distance between the part of the locking member located at the intersection with the mould and the mould plate is less than the sum of the thickness of the mould and the height of the part of the positioning pin exposed on the surface of the mould plate.

[0011] Further, the positioning pin comprises a tail part and a pin head. The tail part is fixedly connected with the mould plate in a threaded mode. The pin head is exposed on the surface of the mould plate, and its height is greater than or equal to the thickness of the mould.

[0012] Further, the base of the locking device is rotatably connected with the locking member around an axis, and the locking member can form two states of non-intersection and intersection with the mould during the rotation.

[0013] Further, the locking member is in the shape of a long sheet, one end of which is fixed to the base around an axis, and the other end is used to form an intersection area with the mould.

[0014] Furthermore, the locking member of the locking device is telescopically arranged on the base. When the locking member is extended, it can intersect with the mold, and when the locking member is retracted, it does not intersect with the mold.

[0015] Furthermore, the locking device also includes a driving device for the locking member, and the driving device is used to drive the locking member to telescopically move on the base.

[0016] Furthermore, the driving device adopts a cylinder, one end of the locking member is connected to the cylinder, and the locking member is driven by the cylinder to extend and retract along the base.

[0017] Furthermore, the cylinder is provided with an air joint and a magnetic switch.

[0018] Furthermore, the base is provided with fixing screws for fixing the locking device to the template.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] There are locating pins and locking devices on both sides of the mold frame's template, and locating holes that match the locating pins on the mold. When the mold is installed on the template, the locking device locks the mold through the intersection with the mold. When the mold frame rotates, the template will also rotate and form different angles of inclination according to the actual production situation. In this case, if the magnetic force fails or the screw breaks, the locating pins will limit the displacement of the mold along the template plane, and the locking device will limit the up and down movement of the mold, thereby preventing the mold from falling.

[0036] In the following description, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0037] like Figure 1 As shown, the utility model discloses a mold anti-dropping device, which is arranged on a template 1 and includes at least two positioning pins 2 installed on the template, the positioning pins cooperate with the positioning holes on the mold; and a locking device installed on the template.

[0038] The positioning pins 2 are protruding from the plane of the template 1 and cooperate with the positioning holes on the mold to limit the displacement of the mold on the template.

[0039] The locking device 3 includes a base 8 mounted on the template and a locking member 9 disposed on the base and movably connected to the base, for controlling the mold on the positioning pin.

[0040] The locking member 9 forms an intersection with the mold, locking the mold through the intersection to prevent it from falling off the positioning pin. The minimum distance between the part of the locking member 9 that intersects with the mold and the template is less than the sum of the thickness of the mold and the height of the part of the positioning pin exposed on the surface of the template.

[0041] The intersection area referred to in this application refers to the overlapping area formed between the locking member and the mold and the projection of the mold onto the template, so that when the mold is about to leave the template, the locking member can lock the mold and prevent the mold from leaving the template.

[0042] Since the main function of the positioning pin 2 is to couple with the positioning hole on the mold to limit the displacement of the mold on the template, as long as it can be fixed to the template and coupled with the positioning hole on the mold, the positioning pin 2 can be a metal column fixed to the template, and the fixing method can be welding, gluing, etc., but is not limited to this.

[0043] In a preferred embodiment of the present invention, Figure 10 As shown, the locating pin includes a tail portion and a locating pin head 13, which is removably screwed into the screw hole of the template. Preferably, the locating pin tail portion 11 has external threads 12, which are installed in the screw hole of the template via the external threads. The locating pin head 13 is cylindrical, with the length of the cylindrical portion exceeding the thickness of the mold. Furthermore, preferably, the locating pin head is provided with a facing flat surface to facilitate installation and removal using tools.

[0044] There are preferably two positioning pins 2, located opposite each other on either side of the template; more preferably, they are located in the middle of the corresponding mold. However, the number of positioning pins is not limited to two, and can be 3, 4, 5, or 6, depending on the cost and size of the mold.

[0045] In one embodiment of the present invention, the locking device 3 is fixedly mounted on the template. Figure 11 As shown, the locking member 9 is connected to the base 8 for rotation around the axis, and the locking member can be rotatably connected to the base of the locking device by bolts, fasteners, etc. During the rotation process, the locking member 9 can be formed into two states with the mold: non-intersecting and intersecting. Preferably, the locking member is in the shape of a long sheet, one end of which is fixed to the base around the axis, and the other end is used to form an intersection with the mold. When there is no intersection, the mold can be easily placed or removed. When intersecting, the locking member 9 locks the mold. In this case, if the magnetic force fails or the screw breaks, the positioning pin will limit the movement of the mold along the template plane, and the locking member 9 will limit the mold from falling off, thereby preventing the mold from falling.

[0046] In another embodiment of the present invention, Figure 2-Figure 9 As shown, the locking member 9 of the locking device 3 is retractable. When the locking member 9 is extended, it intersects with the mold, and when it is retracted, it does not intersect with the mold.

[0047] Preferably, the locking device 3 further comprises a driving device for the locking member, and the driving device is used to drive the locking member to telescopically move on the base.

[0048] Preferably, the driving device adopts a cylinder, one end of the locking member is connected to the cylinder, and the locking member is driven by the cylinder to extend and retract along the base.

[0049] In a preferred embodiment of the present invention, the locking device includes a cylinder 7, a base 8 sealed to the cylinder, and a locking member 9 mounted on the base. One end of the locking member is connected to the cylinder, and the cylinder is driven to cause the locking member to extend and retract. The cylinder 7, base 8, and locking member 9 are connected together by bolts 10.

[0050] The air cylinder 7 is provided with an air joint 5 and a magnetic switch 6 .

[0051] The base 8 is provided with fixing screws 4 for fixing the base to the template 1 .

[0052] During mold frame operation, locking member 9 remains extended, pressing against formwork 1. Compressed air is supplied to cylinder 7 through air connector 5, which drives locking member 9 back and forth. There are two air connectors 5: one closer to base 8 for retracting the locking member, and one farther from base 8 for extending it.

[0053] When the air connection for extending the locking member is connected, the cylinder 7 drives the locking member 9 to extend from the end close to the cylinder to the end away from the cylinder under the action of compressed air. When the air connection for extending the locking member is connected, the cylinder 7 drives the locking member 9 to retract from the end away from the cylinder to the end close to the cylinder.

[0054] There are two magnetic switches 6, which are used to detect the extension and retraction states of the cylinder 7 and output signals to the controller for control.

[0055] There are preferably two locking devices 3, located on opposite sides of the template; more preferably, they are located in the middle of the corresponding mold. However, the number of locking devices 3 is not limited to two, and can be 3, 4, 5, or 6, depending on the cost and size of the mold.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention. In addition, although the elements of the present invention may be described or required in individual form, it is also conceivable to have multiple elements unless expressly limited to a single element.
