DETAILED DESCRIPTION

[0029] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] like Figure 1-Figure 3As shown, the present embodiment provides a removal device for removing the injection molded part 100 from the mold body, wherein the injection molded part 100 is a hollow columnar structure, and the conventional clamping mechanism usually applies a clamping force on two opposite sides of the plastic product to remove it, and this removal method easily causes the plastic product to deform. In order to solve the above problems, the removal device provided in the present embodiment includes a top plate 20 and a clamping assembly 10, the clamping assembly 10 includes a clamping drive 11 and at least two clamping jaws 12, the clamping drive 11 is arranged on the top plate 20, and each clamping jaw 12 includes a connecting portion 121 and an abutting portion 122 arranged at an angle, and the abutting portion 122 extends toward the inner side of the corresponding connecting portion 121, and all the connecting portions 121 are connected to the output end of the clamping drive 11, and can be driven by the clamping drive 11. When the clamping jaws 12 are closed or opened under the action of the mold, at least two clamping jaws 12 can be arranged around the injection molded part 100, and there is a gap between the connecting portion 121 and the injection molded part 100, and the connecting portion 122 can abut against the bottom of the injection molded part 100, so that when the clamping jaws 12 are closed, only the bottom surface of the injection molded part 100 is applied to separate it from the mold body, thereby avoiding deformation of the injection molded part 100 when the clamping jaws 12 apply a clamping force acting oppositely on the injection molded part 100. The injection molded part 100 can be a cylindrical or multi-prism structure.

[0034] It should be noted that the inner side of the connection portion 121 refers to a side where the plurality of connection portions 121 are close to each other, and the outer side of the connection portion 121 refers to a side where the plurality of connection portions 121 are far from each other.

[0035] In this embodiment, the number of the clamping jaws 12 is two, and the two clamping jaws 12 are arranged opposite to each other, so as to reduce the number of the clamping jaws 12 and reduce the production cost under the premise of being able to stably clamp the injection molded part 100. Of course, in other embodiments, the number of the clamping jaws 12 can also be three, four, five, or even more, and the designer can adaptively set the number of the clamping jaws 12 according to the structure of the injection molded part 100.

[0036] Preferably, in this embodiment, the angle between the connecting portion 121 and the abutting portion 122 is greater than or equal to 90°, so that the abutting portion 122 can be inserted into the gap between the injection molded part 100 and the mold body when the clamping jaws 12 are closed, thereby separating the injection molded part 100 from the mold body.

[0037] In this embodiment, the clamping assembly 10 also includes a product positioning block 13, which can extend into the hollow cavity of the injection-molded part 100, thereby jointly defining the position of the injection-molded part 100 with the abutment portion 122. Due to the different structures or orientations of the mold body, when the material picking device transfers the injection-molded part 100 from the mold surface to the next workstation, the material picking device may tilt or flip. The above arrangement can prevent the injection-molded part 100 from falling from the gap between the two jaws 12 during the process of clamping and carrying by the jaws 12.

[0038] like Figure 1 and Figure 4 As shown, in order to achieve the fixation of the product positioning block 13, in this embodiment, the clamping assembly 10 also includes a mounting member 14, and the mounting member 14 is used to fix the product positioning block 13 on the clamping drive member 11. Optionally, one end of the mounting member 14 is connected to the clamping drive member 11, and the product positioning block 13 is detachably connected to the other end of the mounting member 14. The operator can replace the product positioning block 13 according to the size and shape of the hollow cavity of the injection molded part 100. The detachable connection method between the product positioning block 13 and the mounting member 14 includes but is not limited to bolts, screws or buckles, etc., and this embodiment does not limit its connection method. In another embodiment, the mounting member 14 can also be fixed on the top plate 20. In another embodiment, the product positioning block 13 can also be directly fixed on the clamping drive member 11 or the top plate 20.

[0039] In order to improve the efficiency of product removal, the number of clamping assemblies 10 is multiple, and the multiple clamping assemblies 10 are distributed in an array on the top plate 20, and are arranged one by one corresponding to the molding cavities on the mold body. Optionally, in other embodiments, the number of clamping assemblies 10 can be adaptively adjusted according to the use requirements, and all the injection molded parts 100 in the mold body can be removed through one or more material removal processes.

[0040] In order to install the clamping assembly 10 , the removal device further includes a fixing member 30 , which is used to fix the clamping assembly 10 on the top plate 20 , thereby ensuring the stability of the connection between the clamping assembly 10 and the top plate 20 .

[0041] Further, the number of the fixing members 30 is multiple, and each fixing member 30 corresponds to at least one clamping assembly 10, that is, each fixing member 30 can fix at least one clamping assembly 10 to the top plate 20. Specifically, in this embodiment, each fixing member 30 can fix two clamping assemblies 10 to the top plate 20, so as to achieve the effects of saving the fixing members 30, simplifying the structure of the taking-out device, facilitating the installation and disassembly of the clamping assemblies 10, and thus facilitating the maintenance and replacement of the clamping assemblies 10. In this embodiment, the fixing member 30 is in a "U" shape, including a cross plate and two vertical plates. The two vertical plates are respectively arranged at both ends of the cross plate. The cross plate is fixed to the top plate 20, and the two vertical plates are respectively connected to the adjacent two clamping driving members 11. The above setting increases the contact area between the fixing member 30 and the top plate 20 and the clamping driving members 11, thereby ensuring the stability of the connection between the clamping driving members 11 and the top plate 20.

[0042] Further, as Figure 1 and Figure 5 shown, the top plate 20 is provided with an opening 21 corresponding to the clamping assembly 10. The clamping driving member 11 and the clamping jaw 12 are respectively located on both sides of the top plate 20. The connecting portion 121 of the clamping jaw 12 passes through the opening 21 and is connected to the output end of the clamping driving member 11. The above fixing member 30 fixes the clamping driving member 11 to the top plate 20, which is convenient for the clamping driving member 11 to drive the clamping jaw 12 to close and open, and the above setting can make the structure of the taking-out device more compact and improve the space utilization rate.

[0043] A mold positioning block 40 is provided on one of the top plate 20 and the mold body, and a positioning groove for plugging and matching with the mold positioning block 40 is provided on the other, so as to align the top plate 20 with the mold body, and further make the clamping assembly 10 align with the molding cavity on the mold body, so as to accurately take out the injection molded part 100.

[0044] Preferably, the mold positioning block 40 is provided on the top plate 20, and the width of the mold positioning block 40 gradually decreases in the direction away from the top plate 20, so that when the taking-out device is docked with the mold body, the mold positioning block 40 can be smoothly inserted into the positioning groove, thereby driving the top plate 20 to be accurately docked with the mold body.

[0045] Preferably, the distance between the end of the mold positioning block 40 and the top plate 20 is greater than the distance between the end of the clamping jaw 12 and the top plate 20, so as to ensure that the clamping assembly 10 does not contact the mold body or the injection molded part 100 before the top plate 20 is aligned with the mold body, and avoid damage to the mold body, the injection molded part 100 or the clamping assembly 10.

[0046] Continuing as Figure 3As shown, the clamping jaw 12 is provided with an avoidance structure for avoiding the ejection block of the mold body. Specifically, the mold body is provided with an ejection block for ejecting the injection molded part 100 from the molding cavity so that the ejection device can take it out. In order to avoid interference between the clamping jaw 12 and the ejection block, an avoidance groove is provided at one end of the connecting portion 121 away from the clamping driving member 11 to avoid the ejection block directly below the connecting portion 121. The avoidance groove forms the above-mentioned avoidance structure. Specifically, the specific shape of the avoidance groove can be adaptively adjusted according to the structure of the mold molding cavity and the shape and position of the ejection block.

[0047] Preferably, each connection part 121 includes a first connection part and a plurality of second connection parts spaced apart along the length direction of the first connection part, and an abutment part 122 is provided at one end of each second connection part away from the first connection part, and the first connection part is connected to the output end of the clamping drive member 11. The interval between two adjacent second connection parts forms the above-mentioned avoidance groove. In this embodiment, the number of second connection parts of each clamping jaw 12 is two, and the two second connection parts are respectively located at the two ends of the corresponding first connection part. Of course, in other embodiments, the designer can also adjust the number of the second connection parts according to actual needs, which is not limited here.

[0048] After the injection molding is completed, excess waste will be generated around the molding cavity in the mold body. The ejector pin is used to eject the waste. In order to avoid interference between the clamping jaw 12 and the ejector pin, the height of the abutment portion 122 located directly above the ejector pin of the mold body is smaller than the height of the other abutment portions 122 to avoid the ejector pin directly below the abutment portion 122. It should be noted that in order to ensure the structural strength of the clamping jaw 12, the height of the other abutment portions 122 remains unchanged to avoid the connection between the abutment portion 122 and the connecting portion 121 from breaking, thereby extending the service life of the clamping jaw 12.

[0049] The utility model also provides an injection molding device, including a mold body and the above-mentioned removal device, one of the removal device and the mold body can move relative to the other in a direction approaching or moving away from each other, thereby achieving docking of the removal device and the mold body to remove the injection molded part 100 from the mold body.

[0050] like Figure 1As shown, the injection molding equipment also includes a displacement mechanism 200, and the top plate 20 of the removal device is arranged at the output end of the displacement mechanism 200. The displacement mechanism 200 can drive the removal device to approach or move away from the mold body, thereby realizing the docking of the removal device and the mold body to transfer the injection molded part 100 from the mold body to the product receiving box. Specifically, in the present embodiment, the displacement mechanism 200 is a manipulator, which drives the taking-out device close to the mold body, and realizes the positioning of the top plate 20 and the mold body through the mold positioning block 40 and the positioning groove plugged therein, so as to ensure that the clamping assembly 10 is located directly above the molding cavity. In the process of the taking-out device approaching the mold body, the product positioning block 13 is inserted into the hollow cavity of the injection molded part 100, and then the clamping drive 11 drives the jaws 12 to close so that the abutment portion 122 is inserted into the gap between the injection molded part 100 and the mold body. The manipulator drives the taking-out device away from the mold body, thereby taking out the injection molded part 100. Next, the manipulator drives the taking-out device to align with the material receiving box for collecting the injection molded part 100, and the clamping drive 11 drives the jaws 12 to open, so that the injection molded part 100 falls into the material receiving box, thereby completing the taking-out and collection of the injection molded part 100.

[0051] Optionally, in other implementations, the specific structure of the displacement mechanism 200 includes but is not limited to mechanisms such as a lead screw nut, a slide rail or a chain transmission, and this embodiment does not limit its specific structure.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
