DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example 1: A reinforced side-pulling mechanism for large-volume workpieces, such as... Figures 1-6 As shown, it includes a lower module 1, an upper module 2, a molded product 3, and a reinforcing assembly disposed on the lower module 1.

[0032] The enhanced group includes the side-pump group and the center-pump group.

[0033] The side-pull assembly includes a reinforcing plate 10 and a side positioning block 6. The reinforcing plate 10 is fixedly installed on the outer surface of the lower module 1. The side positioning block 6 is inserted into the outer side of the molded product 3 and is located inside the reinforcing plate 10. The reinforcing plate 10 is used to limit the movement of the side positioning block 6.

[0034] The middle ejection assembly includes a middle ejection block 4 and a middle push rod 13. There are several middle ejection blocks 4, and all of them are located inside the molded product 3. The outer surface of the middle ejection blocks 4 is in close contact with the inner surface of the molded product 3. The middle push rod 13 is installed at the lower end of the middle ejection block 4.

[0035] Furthermore, the side drawers have a forced limiting effect, while the middle drawers have a large-angle support effect.

[0036] First, based on the core-pulling support of the side positioning block 6 inside the side-pulling group, the core-pulling process is performed on both sides of the molded product 3 after molding. Based on the reinforcing plate 10 installed on the side of the lower module 1, the reinforcing plate 10 is fixed on the lower module 1, which can forcibly limit the movement distance of the side positioning block 6. This prevents the side positioning block 6 from moving due to the large structure of the molded product 3 itself during injection molding. This ensures the stability and accuracy of the device during injection molding. With the combined use of multiple central ejector blocks 4 and central push rods 13 in the middle-pulling group, after the core-pulling of the side-pulling group is completed, it increases the thrust from below the molded product 3, pushing the molded product 3 upward. Under the guidance and support of multiple long-specification central push rods 13, the device achieves a stable demolding effect.

[0037] like Figures 1-6 As shown, the molded product 3 has at least two side grooves 5 on its outer side. The two side grooves 5 are symmetrically distributed, and the side positioning block 6 is inserted into the side groove 5.

[0038] Based on the positioning and guiding of the positioning blocks 6 on both sides, the accuracy of the specifications of the two side edge grooves 5 of the molded product 3 after molding is ensured, and under the positioning and guiding of the molded product 3 and the side edge groove 5, the accuracy of the movement of the side positioning block 6 in the direction of the side edge is ensured, and the position of the side positioning block 6 is reinforced to improve the stability of the position of the two side parts during injection molding of the device.

[0039] As shown in Figures 1-6 , the side extraction group further includes a connecting block 7, a sliding groove 8, and a limiting block 9. The connecting block 7 and the limiting block 9 are located between the side positioning block 6 and the reinforcing plate 10. The sliding groove 8 penetrates the side of the connecting block 7 close to the limiting block 9. The limiting block 9 has a sliding guide rail installed inside.

[0040] The side extraction group further includes a driving cylinder 11 for driving support. The driving cylinder 11 is installed on the outside of the lower mold block 1 through a support seat. The driving cylinder 11 and the reinforcing plate 10 each have at least two. The two driving cylinders 11 and the reinforcing plate 10 are located on opposite sides of the lower mold block 1. The output end of the driving cylinder 11 is connected with the limiting block 9.

[0041] During demolding, the driving cylinder 11 is first started to drive the limiting block 9 to shrink synchronously, so that the guide rail on one side of the limiting block 9 moves synchronously inside the sliding groove 8. By moving the limiting block 9 out, the limiting of the connecting block 7 and the reinforcing plate 10 is released, so that the connecting block 7 can be extracted, and the side positioning block 6 is moved synchronously to achieve the effect of stably extracting the side positioning block 6 from the side edge groove 5. During molding, the driving cylinder 11 is started to move the limiting block 9 towards the connecting block 7 and the reinforcing plate 10. Based on the inclined structure of the contact surface between the limiting block 9 and the connecting block 7, the limiting block 9 is limited to move from the largest end of the opening of the sliding groove 8 to the smallest end of the specification, to ensure the accuracy of the insertion of the limiting block 9 into the sliding groove 8. Under the continuous movement of the limiting block 9 and based on the position fixation of the reinforcing plate 10 itself, the connecting block 7 is forced to move towards the inside of the device based on the gradually increasing contact surface between the limiting block 9 and the connecting block 7, so as to achieve the effect of inserting the side positioning block 6 into the side edge groove 5. Under the limiting of the limiting strip at the top end of the limiting block 9, the movement distance of the limiting block 9 is stable, and finally the side positioning block 6, the connecting block 7, the limiting block 9, and the reinforcing plate 10 are in a fastened state, so that the side positioning block 6 is further positioned and supported by the reinforcing plate 10 to ensure the stability of the position of the side positioning block 6 during injection molding of the device. By setting the movable distance of the connecting block 7 to be slightly larger than the distance of the side positioning block 6 extracted from the side edge groove 5, the stability and accuracy of the device during demolding are ensured.

[0042] Embodiment two: a reinforcing side extraction mechanism for large-volume workpieces, as shown in Figures 1-6As shown, the reinforcing plate 10 is provided with a plurality of fastening holes 12, which are used for connecting the external fastening bolts and connecting the lower module 1.

[0043] By providing a plurality of fastening holes 12 on the reinforcing plate 10 and fixing the reinforcing plate 10 on the lower module 1 by using a plurality of fastening bolts, the support strength of the reinforcing plate 10 during use is further ensured, and the reinforcing effect of the device is improved.

[0044] As shown, Figures 1-6 The middle push rod 13 is inserted into the support base 15, and the middle push rod 13 is inserted into the horizontal sliding block 16. The horizontal sliding block 16 is horizontally slidably arranged in the support base 15.

[0045] The upper half of the middle push rod 13 is inserted into the angle positioning block 14, and the angle positioning block 14 is fixedly installed in the lower module 1.

[0046] By positioning and guiding under the angle positioning block 14, the stability of the overall angle of the middle push rod 13 during movement is ensured, and the angle movement is prevented, so that the middle push rod 13 has stable support effect under large angle support, and the stability of the upward pushing from the middle is ensured.

[0047] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical range disclosed by the present application, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change, which should be covered within the protection scope of the present application.
