[0044] In this embodiment, when the injection molding production is carried out by the device, the molten raw material is injected into the mold cavity composed of the lower mold core 2, the upper mold plate 3, the slider one 4 and the slider two 5 through the injection channel 301 after the mold is aligned by the injection molding machine, and after waiting for solidification and molding, the mold is opened by moving the slider one 4 and the slider two 5 away from each other, and when the slider one 4 moves outward, the connecting plate one 8 connected by the connecting block one 6 pulls the diagonal ejector slide 9 to move, and the movement of the diagonal ejector slide 9 drives the diagonal ejector rod 10 to stretch out to one side of the mold cavity, thereby ejecting the product from the mold cavity, achieving the purpose of automatic demolding;

[0045] After one product is demolded, the slider one 4 and the slider two 5 are driven to move in the direction of approaching each other by the extension of the oil cylinder one 7 and the oil cylinder two 12 respectively, so that the lower mold core 2, the upper mold plate 3, the slider one 4 and the slider two 5 are molded again in sequence to form the mold cavity of the product, and then the raw material is injected into the mold cavity to form the product again, and when the slider one 4 moves inward to close the mold, the diagonal ejector slide 9 is pushed to move away from the diagonal ejector rod 10 due to the connection of the connecting block one 6, the connecting plate one 8 and the diagonal ejector slide 9, so that the diagonal ejector rod 10 loses the support of the diagonal ejector slide 9 and is retracted into the mold, facilitating the molding production of the product.

[0046] In a preferred embodiment, please refer to Figure 3 and Figure 6 As shown in the drawings, the inner side of the lower mold plate 1 is provided with a sliding groove one 101, the diagonal ejector slide 9 is slidingly arranged in the sliding groove one 101, the upper side of the sliding groove one 101 is provided with a diagonal guide groove 102, and the diagonal guide groove 102 is in communication with the mold cavity of the injection mold, the diagonal ejector rod 10 is connected in the diagonal guide groove 102, the lower end face of the lower mold plate 1 is provided with a mounting hole 103, and the mounting hole 103 is arranged in alignment with the diagonal guide groove 102, and the upper end face of the lower mold plate 1 is provided with a sliding groove 104 on the left and right sides;

[0047] In this embodiment, the chute one 101 provides space for the installation of the inclined top sliding block 9, and facilitates the sliding of the inclined top sliding block 9 along the chute one 101, so that the movement of the inclined top sliding block 9 is more stable, and the inclined guide groove 102 facilitates the penetration of the inclined top rod 10 into the mold cavity, facilitates the ejection of the product from the mold cavity, and provides a guide function for the extension and retraction movement of the inclined top rod 10, and the installation port 103 facilitates the penetration of the inclined top rod 10 from the outside into the inclined guide groove 102, facilitating the assembly of the mold.

[0048] Secondly, please refer to Figures 8-9 and Figure 10 It is shown that the inner wall of the inclined guide groove 102 is provided with a clamping groove 105, the side surface of the inclined top rod 10 is provided with a clamping block 1002 clamped in the clamping groove 105, and the inner side of the lower die plate 1 is provided with a guide hole 106 at four corners, respectively, and the lower end surface of the upper die plate 3 is provided with a guide rod 302 at four corners corresponding to the guide hole 106, and the guide rod 302 is connected in the guide hole 106;

[0049] The clamping groove 105 is arranged in the inclined guide groove 102, which facilitates the clamping of the clamping block 1002 of the inclined top rod 10 into the clamping groove 105, thereby avoiding deflection during the extension and retraction of the inclined top rod 10. The clamping block 1002 clamped into the clamping groove 105 can only make the inclined top rod 10 move along the central axis of the inclined guide groove 102, thereby ensuring the stability of the extension and retraction of the inclined top rod 10. Furthermore, the installation of the guide rod 302 on the upper die plate 3 and the connection into the guide hole 106 can guide the transformation of the mold opening and closing between the upper die plate 3 and the lower die plate 1, preventing collision due to misalignment.

[0050] Please refer to Figure 2 and Figure 3 The inner side of the upper die plate 3 is provided with an injection channel 301 connected with the mold cavity;

[0051] By providing the injection channel 301 on the upper die plate 3, the injection channel 301 is connected with the mold cavity, which facilitates the injection of raw materials into the mold cavity by the injection molding machine. Furthermore, the internal structure of the upper die plate 3 is simpler compared with the lower die plate 1, which is more suitable for the establishment of the injection channel 301.

[0052] In a preferred embodiment, please refer to Figure 3 and Figure 4 and Figure 7 The outer side of the connecting block one 6 is connected with an oil cylinder one 7 for driving the sliding block one 4 to slide, the outer side of the sliding block one 4 is fixedly connected with a sliding block 401 at the lower end through bolts, the sliding block 401 is slidingly arranged in the chute 104, and the connecting block one 6 and the connecting plate one 8 are fixedly connected through bolts;

[0053] In this embodiment, the movement of the slider 4 is driven by the extension and retraction of the oil cylinder 7, thereby realizing the opening and closing of the mold between the molds, and when the slider 4 moves, the sliding block 401 moves along the sliding groove 104, thereby improving the stability of the movement of the slider 4, and the sliding block 401 and the slider 4 are connected by bolts, facilitating assembly, and during processing, the parts can be processed separately and then assembled, improving the convenience of processing. Similarly, the connecting block 6 and the connecting plate 8 are easy to assemble and process.

[0054] Secondly, please refer again to Figure 4 As shown, the outer side of the slider 5 is connected with the connecting block 11, the outer side of the connecting block 11 is connected with the oil cylinder 12 for driving the slider 5 to slide, the outer side of the slider 5 is connected with the sliding block 401, and the sliding block 401 is slidably arranged in the sliding groove 104;

[0055] For the driving of the slider 5, the extension and retraction of the oil cylinder 12 is used to drive the slider 5 to slide along the sliding groove 104, thereby improving the stability of the movement of the slider 5, and the slider 5 and the oil cylinder 12 are connected by the connecting block 11, facilitating the assembly and production of the equipment.

[0056] Thirdly, please refer to Figure 4 As shown, the inclined top slider 9 comprises a sliding plane 901, a connecting curved surface 902 and an inclined top surface 903, the sliding plane 901 is a horizontal state plane, the connecting curved surface 902 is arranged tangent to the sliding plane 901 and the inclined top surface 903, and the inclined top surface 903 is an inclined structure plane;

[0057] In the embodiment, when the position of the inclined top slider 9 is adjusted to drive the inclined top rod 10, the inclined top slider 9 is moved to the side close to the inclined top rod 10 by the retraction of the oil cylinder 7 at the time of mold opening, and the inclined top rod 10 is gradually lifted by the gradually close of the inclined top surface 903 of the inclined top slider 9 to the inclined top rod 10, so that the inclined top rod 10 is extended to the side of the mold cavity, and the product is ejected, and the mold is opened. In order to avoid the situation that the slider 4 and the slider 5 are not completely separated from the product when the inclined top rod 10 is extended, and the product is easily damaged when the inclined top rod 10 ejects the product, a sliding plane 901 is arranged on the inclined top slider 9, and the sliding plane 901 is horizontally arranged, that is, the inclined top rod 10 is not lifted when moving on the sliding plane 901, so as to provide a distance for the complete separation of the slider 4 and the slider 5 from the product. In the specific practice process, the retraction of the oil cylinder 7 drives the slider 4 to move outward, and at the same time drives the inclined top slider 9 to move to the side close to the inclined top rod 10. At this time, the inclined top rod 10 moves a distance on the sliding plane 901, and the inclined top rod 10 is not lifted. When the slider 4 is completely separated from the product, the inclined top rod 10 just contacts the inclined top surface 903, and the retraction of the oil cylinder 7 drives the inclined top surface 903 to gradually close to the inclined top rod 10, so that the inclined top rod 10 is lifted to eject the product from the mold cavity. The connection of the arc surface 902 makes the connection between the sliding plane 901 and the inclined top surface 903 more smooth.

[0058] In a preferred embodiment, please refer to Figure 4 The spring 13 is sleeved on the inclined top rod 10, the upper end of the spring 13 is abutted on the inclined guide groove 102, the lower end of the spring 13 is abutted on the inclined top rod 10, the top end of the inclined top rod 10 is provided with the ejector block 1001, and the ejector block 1001 is fixedly connected with the inclined top rod 10 through the countersunk head bolt.

[0059] In the embodiment, when the inclined top rod 10 loses the support of the inclined top slider 9, the spring 13 can drive the inclined top rod 10 to retract into the mold, and at the same time, the ejector block 1001 is retracted, so as to facilitate the re-injection production of the product.

[0060] Please refer to Figure 6 In the injection production, the ejector block 1001 is retracted into the lower mold core 2, and the upper end surface of the lower mold core 2 is flush with the upper end surface of the ejector block 1001.

[0061] When demolding in injection molding production, the product is ejected by the inclined ejector rod 10 driving the ejector block 1001, and the ejector block 1001 is flush with the lower mold core 2, which can completely hide the ejector block 1001 in the lower mold core 2, avoid affecting the production of the product, and at the same time, the use of the countersunk bolt can facilitate the installation of the ejector block 1001 and the inclined ejector rod 10, and at the same time, it does not affect the production.

[0062] Example two

[0063] Compared with example one, the inclined ejector rod 10 and the inclined ejector slide 9 are increased with a roller 14 at the contact end of the inclined ejector rod 10.

[0064] Please refer to Figure 5 As shown, the lower end of the inclined ejector rod 10 is provided with a roller 14, and the inclined ejector rod 10 is connected with the inclined ejector slide 9 through the roller 14.

[0065] In this embodiment, the lower end of the inclined ejector rod 10 is increased with a roller 14 structure, so that the sliding adjustment between the inclined ejector rod 10 and the inclined ejector slide 9 becomes rolling adjustment, thereby reducing the friction between the inclined ejector rod 10 and the inclined ejector slide 9, improving the service life of the mold, and enabling the mold to have better stability.

[0066] The working principle of the present application is as follows: when the device is used for injection molding production, the molten raw material is injected into the mold cavity composed of the lower mold core 2, the upper mold plate 3, the slide block one 4 and the slide block two 5 through the injection channel 301 of the injection molding machine, and after waiting for solidification and molding, the mold is opened by moving the slide block one 4 and the slide block two 5 away from each other, and when the slide block one 4 moves outward, the connecting plate one 8 connected by the connecting block one 6 pulls the movement of the inclined ejector slide 9, which in turn drives the inclined ejector rod 10 to extend to one side of the mold cavity, thereby ejecting the product from the mold cavity, achieving the purpose of automatic demolding.

[0067] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
