[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0042] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0043] See also Figure 1-Figure 3 As shown, the present invention provides an oblique synchronous ejection injection mold, comprising: a lower mold plate 1, a lower mold core 2 and an upper mold plate 3; the lower mold core 2 is installed on the upper end surface of the lower mold plate 1, and the upper mold plate 3 is used in conjunction with the lower mold core 2; a slider 4 and a slider 2 5 are respectively arranged on the left and right sides between the lower mold plate 1 and the upper mold plate 3; the outer side surface of the slider 4 is connected to a connecting block 6, the inner side surface of the lower end of the connecting block 6 is connected to a connecting plate 8, and the connecting plate 8 is connected to an inclined ejection slider 9 at a distance from the connecting block 6; an inclined ejector rod 10 is penetrated through the inner side of the lower mold plate 1 and the lower mold core 2, and the top end of the inclined ejector rod 10 points to the mold cavity of the injection mold, and the lower end of the inclined ejector rod 10 presses on the upper end surface of the inclined ejector slider 9;

[0044] In this embodiment, when the device is used for injection molding, the molten raw material is injected into the mold cavity composed of the lower mold core 2 and the upper mold plate 3 and the slider 1 4 and the slider 2 5 through the injection molding machine aligned with the injection channel 301 after the mold is closed. After waiting for solidification and molding, the mold is opened by moving the slider 1 4 and the slider 2 5 away from each other, and when the slider 1 4 moves outward, the connecting plate 1 8 connected to the connecting block 1 6 will pull the inclined ejector slider 9 to move, and the movement of the inclined ejector slider 9 will push 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;

[0045] After a product is demoulded, the extension of the oil cylinder 1 7 and the oil cylinder 2 12 is used to drive the slider 1 4 and the slider 2 5 to move towards each other, so that the lower mold core 2 and the upper mold plate 3 as well as the slider 1 4 and the slider 2 5 are molded in sequence again to form a mold cavity of the product, and then the raw material is injected into the mold cavity to form the product again. When the slider 1 4 moves inward to close the mold, due to the connection between the connecting block 1 6 and the connecting plate 1 8 and the inclined top slider 9, the inclined top slider 9 will be pushed to move away from the inclined top rod 10, so that the inclined top rod 10 loses the supporting force of the inclined top slider 9, and thus will retract into the mold, which is convenient for the molding and production of the product.

[0046] In a preferred embodiment, please refer to Figure 3 and Figure 6 As shown, a slide groove 101 is provided on the inner side of the lower template 1, and the inclined top slider 9 is slidably arranged inside the slide groove 101. An inclined guide groove 102 is provided above the slide groove 101, and the inclined guide groove 102 is communicated with the mold cavity of the injection mold. The inclined top rod 10 is connected in the inclined guide groove 102. A mounting opening 103 is provided on the lower end surface of the lower template 1, and the mounting opening 103 is aligned with the inclined guide groove 102. Slide grooves 104 are respectively provided on the left and right sides of the upper end surface of the lower template 1.

[0047] In this embodiment, the setting of the slide groove 101 provides space for the installation of the inclined top slider 9, and facilitates the inclined top slider 9 to slide along the slide groove 101, so that the movement and adjustment of the inclined top slider 9 is more stable, and the setting of the inclined guide groove 102 facilitates the insertion of the inclined top rod 10 to reach the mold cavity, facilitates the ejection of the product from the mold cavity, and provides a guide for the telescopic movement of the inclined top rod 10, and the setting of the installation port 103 facilitates the insertion of the inclined top rod 10 into the inclined guide groove 102 from the outside, thereby facilitating the assembly of the mold.

[0048] Next, please refer to Figure 8-Figure 9 and Fig.10 As shown, a slot 105 is provided on the inner wall of the inclined guide groove 102, a block 1002 engaged in the slot 105 is provided on the side of the inclined ejector rod 10, guide holes 106 are provided at the four inner corners of the lower template 1, and guide rods 302 are installed at the four corners of the lower end surface of the upper template 3 corresponding to the guide holes 106, and the guide rods 302 are connected in the guide holes 106;

[0049] A card slot 105 is set in the inclined guide groove 102 to facilitate the card block 1002 of the inclined ejector rod 10 to be carded into the card slot 105, thereby avoiding deflection during the telescopic change of the inclined ejector rod 10. The card block 1002 is carded into the card slot 105, and the movement of the inclined ejector rod 10 in the inclined guide groove 102 can only make the inclined ejector rod 10 telescopically move along the central axis of the inclined guide groove 102, thereby ensuring the telescopic stability of the inclined ejector rod 10, and the guide rod 302 is installed on the upper template 3 and connected to the guide hole 106, which can guide the opening and closing changes between the upper template 3 and the lower template 1 to prevent misalignment and collision.

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

[0051] By opening the injection channel 301 on the upper template 3, the injection channel 301 is connected to the mold cavity, which facilitates the injection molding machine to inject raw materials into the mold cavity. Compared with the lower template 1, the internal structure of the upper template 3 is simpler and more suitable for the opening of the injection channel 301.

[0052] In a preferred embodiment, please refer to Figure 3 and Figure 4 as well as Figure 7 As shown, the outer side of the connecting block 6 is connected to a cylinder 7 for driving the sliding block 4 to slide, the lower end of the outer side of the sliding block 4 is fixedly connected to a sliding block 401 by bolts, the sliding block 401 is slidably arranged in the sliding groove 104, and the connecting block 6 and the connecting plate 8 are fixedly connected by 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 molds, and when the slider 4 moves, it will move along the slide groove 104 through the sliding block 401, so as to improve the stability of the slider 4 when moving, and the sliding block 401 is connected to the slider 4 by bolts, which is convenient for assembly, and during processing, the parts can be processed separately and then assembled, which improves the convenience of processing. Similarly, the connection block 6 and the connection plate 8 are easy to assemble and process.

[0054] Next, please refer to Figure 4 As shown, the outer side of the slider 2 5 is connected to the connecting block 2 11, the outer side of the connecting block 2 11 is connected to the oil cylinder 2 12 for driving the slider 2 5 to slide, and the lower end of the outer side of the slider 2 5 is installed with a sliding block 401, and the sliding block 401 is slidably set in the slide groove 104;

[0055] The driving of the slider 25 is driven by the extension and retraction of the cylinder 212. Similarly, when the cylinder 212 drives the slider 25 to move, the slider 25 will drive the sliding block 401 to slide along the slide groove 104, thereby improving the stability of the movement of the slider 25. The slider 25 and the cylinder 212 are connected and transmitted by the connecting block 211, which is convenient for the assembly and production of the equipment.

[0056] Secondly, please refer to Figure 4 As shown, the inclined top slider 9 includes a sliding plane 901, a connecting arc surface 902 and an inclined top surface 903. The sliding plane 901 is a horizontal plane. The connecting arc surface 902 is tangent to the sliding plane 901 and the inclined top surface 903 respectively. The inclined top surface 903 is an inclined structural plane.

[0057] In this embodiment, when the inclined ejector rod 10 is driven by adjusting the position of the inclined ejector slide block 9, when the mold is opened, the inclined ejector slide block 9 is driven to move to the side close to the inclined ejector rod 10 by the retraction of the oil cylinder 1 7, and the inclined ejector rod 10 is gradually lifted up by the inclined top surface 903 of the inclined ejector slide block 9 gradually approaching the inclined ejector rod 10, so that the inclined ejector rod 10 is extended to one side of the mold cavity, so as to achieve the purpose of ejecting the injection molded product and realize demoulding. In order to avoid the situation that when the inclined ejector rod 10 is extended, the slider 1 4 and the slider 2 5 have not been completely separated from the product, and the inclined ejector rod 10 pushes the product for demoulding at this time, the product is easily damaged. Therefore, a sliding plane 901 is set on the inclined ejector slide block 9, and the sliding plane 901 is set horizontally, that is, when the inclined ejector rod 10 moves on the sliding plane 901, When the slider 14 is completely out of contact with the product, the inclined ejector 10 will not be lifted up, thereby leaving enough distance for the slider 14 and the slider 2 5 to be completely demolded from the product. In the specific practice, when the retraction of the cylinder 17 drives the slider 14 to move outward, it will also drive the inclined ejector slider 9 to move toward the direction close to the inclined ejector 10. At this time, the inclined ejector 10 will move a distance on the sliding plane 901. At this time, the inclined ejector 10 will not be lifted up. After the slider 14 is completely out of contact with the product, the inclined ejector 10 just touches the inclined top surface 903. By continuing to retract the cylinder 17 for a while, the inclined top surface 903 is driven to gradually approach the inclined ejector 10, and the inclined ejector 10 can be lifted up to achieve the purpose of ejecting the product out of the mold cavity. The setting of the connecting arc surface 902 makes the connection between the sliding plane 901 and the inclined top surface 903 smoother.

[0058] In a preferred embodiment, please refer to Figure 4 A spring 13 is sleeved on the inclined ejector rod 10, the upper end of the spring 13 is pressed against the inclined guide groove 102, and the lower end of the spring 13 is pressed against the inclined ejector rod 10. A push block 1001 is installed on the top of the inclined ejector rod 10, and the push block 1001 is fixedly connected to the inclined ejector rod 10 by a countersunk bolt;

[0059] In this embodiment, when the inclined ejector rod 10 loses the supporting force of the inclined ejector slider 9, the elastic force of the spring 13 can drive the inclined ejector rod 10 to retract into the mold, and when the inclined ejector rod 10 retracts, the pushing block 1001 will also be retracted at the same time, which is convenient for the re-injection production of the product.

[0060] See also Figure 6 As shown, during injection molding, 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] During demoulding in injection molding production, the ejector block 1001 is driven by the inclined ejector rod 10 to eject the product, and the ejector block 1001 is arranged flush with the lower mold core 2, so that the ejector block 1001 can be completely hidden in the lower mold core 2 to avoid affecting the production of the product. At the same time, the countersunk bolts can facilitate the installation of the ejector block 1001 and the inclined ejector rod 10 without affecting the production.

[0062] Embodiment 2

[0063] Compared with the first embodiment, the second embodiment adds a roller 14 at the end where the inclined lift rod 10 contacts the inclined lift slider 9;

[0064] See also Figure 5 As shown, a roller 14 is installed at the lower end of the inclined lift rod 10, and the inclined lift rod 10 is rollingly connected to the inclined lift slider 9 through the roller 14.

[0065] In this embodiment, a roller 14 structure is added to the lower end of the inclined lift rod 10, so that the sliding adjustment between the inclined lift rod 10 and the inclined lift slider 9 is changed to rolling adjustment, thereby reducing the friction between the inclined lift rod 10 and the inclined lift slider 9, improving the service life of the mold, and making the mold more stable in use.

[0066] The working principle of the present invention 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 slider 1 4 and the slider 2 5 through the injection molding machine aligned with the injection channel 301, and after waiting for solidification and molding, the mold is opened by moving the slider 1 4 and the slider 2 5 away from each other, and when the slider 1 4 moves outward, the connecting plate 1 8 connected to the connecting block 1 6 will pull the inclined ejector slider 9 to move, and the movement of the inclined ejector slider 9 will push the inclined ejector rod 10 to extend to one side of the mold cavity, thereby ejecting the product from the mold cavity, thereby achieving the purpose of automatic demolding.

[0067] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
