The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The mold positioning device of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the mold positioning device of the embodiment of the utility model may include a workbench 1, a hydraulic telescopic rod 2, a first mold 3, a plurality of positioning pins 4, a second mold 5, a blanking assembly 6 and a conveyor 7.

[0023] Wherein, a first mounting plate 10 and a second mounting plate 11 are respectively arranged on both sides of the workbench 1, the hydraulic telescopic rod 2 is arranged on the second mounting plate 11, the first mold 3 is arranged on the first mounting plate 10, a material pushing groove 30 is opened on the first mold 3, one end of a plurality of positioning pins 4 are respectively arranged on the first mold 3, the other end of the positioning pins 4 are respectively arranged on the second mounting plate 11, the second mold 5 is slidably arranged on the positioning pins 4, and one end of the second mold 5 is connected to the extension shaft of the hydraulic telescopic rod 2;

[0024] It should be noted that the first mold 3 described in this embodiment is fixedly set on the first mounting plate 10, and the second mold 5 is slidably set on the positioning pin shaft 4. The second mold 5 is plugged into and matched with the first mold 3 under the telescopic control of the hydraulic telescopic rod 2. The sliding connection of the second mold 5 on the positioning pin shaft 4 can ensure the sliding positioning of the first mold 3 and the second mold 5, so that the first mold 3 and the second mold 5 always slide on the same axis, and can avoid the situation where the mold offset damages the positioning pin and the positioning hole.

[0025] The material unloading assembly 6 may include a joint control mechanism 60 and a material pushing mechanism 61 .

[0026] Among them, one end of the joint control mechanism 60 is connected to the second mold 5, and the other end of the joint control mechanism 60 is slidably abutted against the pushing mechanism 61. The pushing mechanism 61 is arranged in the pushing groove 30 and is gap-matched with the pushing groove 30; the conveyor 7 is arranged on the workbench 1 and is arranged below the first mold 3.

[0027] It can be understood that, through the setting of the pushing mechanism 61, after the injection molding of the injection molded parts in the mold is completed, the hydraulic telescopic rod 2 retracts to drive the joint control mechanism 60 and the pushing mechanism 61, and the pushing mechanism 61 pushes the injection molded parts in the first mold 3 out for unloading, and under the transportation of the conveyor 7, the continuous unloading of the injection molded parts is realized, and there is no need for manual unloading by relevant personnel, thereby improving the processing efficiency of the mold.

[0028] Specifically, in the actual operation process, the relevant staff starts the device, and the controller (not shown in the figure) controls the hydraulic telescopic rod 2 to extend, driving the second mold 5 to slide on the positioning pin shaft 4, and plugging and cooperating with the first mold 3 to form an injection cavity. The injection molding equipment (not shown in the figure) injects into the injection cavity. After the injection molding is completed, the injection molded part is formed, and the hydraulic telescopic rod 2 drives the second mold 5 to retract, and drives the joint control mechanism 60 to move toward the second mold 5. The joint control mechanism 60 pushes the pushing mechanism 61 to extend on the first mold 3, thereby pushing the injection molded part on the first mold 3 out and unloading it to the conveyor 7, so as to realize the continuous unloading of injection molded parts and improve the processing efficiency of the mold.

[0029] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the linkage mechanism 60 may include a linkage rod 600 and a first elastic telescopic rod 601 .

[0030] Among them, one end of the linkage rod 600 is connected to the second mold 5, and the other end of the linkage rod 600 is connected to the first elastic telescopic rod 601. The first elastic telescopic rod 601 is slidably set in the limiting hole 100 opened in the first mounting plate 10, and one end of the first elastic telescopic rod 601 is slidably abutted against the pushing mechanism 61.

[0031] It should be noted that the first elastic telescopic rod 601 described in this embodiment is a common elastic telescopic rod on the market. Through the setting of the first elastic telescopic rod 601, when the second mold 5 is linked to the linkage rod 600, the extension length of the pushing mechanism 61 can be controlled to prevent the pushing mechanism 61 from being excessively extended and affecting the resetting of the pushing mechanism 61.

[0032] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the pushing mechanism 61 may include a pushing block 610 and two second elastic telescopic rods 611 .

[0033] Among them, the pushing block 610 is arranged in the pushing groove 30 and is gap-matched with the pushing groove 30, and the extending axis of the first elastic telescopic rod 601 is slidingly abutted against the pushing block 610, and the two second elastic telescopic rods 611 are respectively arranged in the plug holes 31 opened on the first mold 3, one end of the second elastic telescopic rod 611 is connected to the first mounting plate 10, and the other end of the second elastic telescopic rod 611 is connected to the pushing block 610.

[0034] It should be noted that the second elastic telescopic rod 611 described in this embodiment is also a common elastic telescopic rod on the market, and its structure is not described in detail.

[0035] It should be noted that the push block 610 described in this embodiment is consistent with the push groove 30, so as to ensure the injection molding quality of the injection molded part.

[0036] It is understandable that the push block 610 can be limited by the provision of the second elastic telescopic rod 611 , and after the push block 610 is pushed out by the first elastic telescopic rod 601 , the push plate can be reset under the action of the second elastic telescopic rod 611 .

[0037] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, a model groove 32 is provided on the first mold 3 , and a model block 51 is provided on the second mold 5 . The model block 51 is plugged into and matched with the model groove 32 .

[0038] It should be noted that the model groove 32 described in this embodiment is connected to the push groove 30, the push groove 30 is connected to the plug hole 31, and the plug hole 31 is connected to the limit hole 100, thereby ensuring that the first elastic telescopic rod 601 can pass through the limit hole 100 and the plug hole 31, pushing the push block 610 to extend, thereby realizing the loading and unloading of injection molded parts from the first mold 3 to the conveyor 7.

[0039] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, a buffer pad 50 is provided on the second mold 5 .

[0040] It can be understood that, by providing the buffer gasket 50 , the extrusion of the first mold 3 and the second mold 5 can be buffered, thereby reducing the wear of the first mold 3 and the second mold 5 .

[0041] Specifically, in the actual operation process, the relevant staff starts the device, and the controller (not shown in the figure) controls the hydraulic telescopic rod 2 to extend, driving the second mold 5 to slide on the positioning pin shaft 4, and plugging and cooperating with the first mold 3 to form an injection cavity. The injection molding equipment (not shown in the figure) injects into the injection cavity. After the injection molding is completed, the injection molded part is formed, and the hydraulic telescopic rod 2 drives the second mold 5 to retract, and drives the linkage rod 600 and the first elastic telescopic rod 601 to move in the direction of the second mold 5, and the first elastic telescopic rod 601 abuts against the push block 610, so that the push block 610 extends out of the first mold 3, thereby pushing the injection molded part on the first mold 3 out and unloading it to the conveyor 7, thereby realizing continuous unloading of injection molded parts and improving the processing efficiency of the mold.

[0042] In summary, the mold positioning device of the embodiment of the utility model can prevent the mold from offsetting and damaging the positioning pins and positioning holes. At the same time, the movement of the mold positioning device can control the unloading of the injection molded parts in a linked manner, thereby improving the processing efficiency of the mold.
