Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0033] like Figure 1-4 As shown, a reaction cup injection molding device includes a bracket 1, a mold 1 2 that is coupled to the inner side of the bracket 1 through a driving component, and a mold 2 3 that is arranged on the inner side of the bracket 1.

[0034] A feeding assembly 4 and a cooling assembly 5 are also provided on the inner side of the bracket 1, and a blanking assembly is provided in the mold 2, which includes a slide 7 and a plurality of ejector rods 9 fixed to the outer wall of the slide 7. A slide groove 6 is provided on the inner wall of the mold 2, and the slide 7 slides in the inner wall of the slide groove 6, and a plurality of springs 8 are buckled on the opposite sides of the slide groove 6 and the slide 7. A plurality of cavities 10 with the same number as the ejector rods 9 are provided on the inner wall of the mold 2, and a plurality of protruding rods 12 with the same number as the ejector rods 9 and the cavities 10 are fixedly connected to the inner wall of the mold 2 3, and a plurality of push rods 11 are also fixedly connected to the outer wall of the slide 7.

[0035] The driving assembly drives the mold 2 to move. When the push rod 11 contacts the outer wall of the mold 2 3, the mold 2 continues to move, so that the push rod 11 drives the ejector rod 9 and the slide plate 7 to move inward, and the spring 18 is elastically deformed under the force. When the mold 12 is fitted with the mold 2 3, the protruding rod 12 is located in the cavity 10. At this time, the feeding assembly 4 is used to inject the molten plastic into the gap between the cavity 10 and the protruding rod 12, and the cooling assembly 5 is used for cooling and molding. After the injection molding is completed, the driving assembly drives the mold 2 to move in the opposite direction. The spring 18 uses its own elasticity to push the slide plate 7, the ejector rod 9 and the push rod 11 to move outward and reset. The ejector rod 9 pushes the reaction cup in the cavity 10 out to achieve unloading.

[0036] By providing the slide plate 7, spring 1-8, ejector pin 9 and push rod 11, the elasticity of spring 1-8 can be used to push the ejector pin 9 outward after injection molding, thereby ejecting the reaction cup in the cavity 10 to achieve automatic unloading, reduce manual operation steps, and improve the injection molding efficiency of the device.

[0037] In this embodiment, a through hole 13 is formed on the inner wall of the protruding rod 12 , a connecting cavity 14 communicating with the through hole 13 is formed on the inner wall of the mold 2 3 , and a feeding pipe 15 communicating with the connecting cavity 14 is fixedly connected to the inner wall of the mold 2 3 .

[0038] The feeding assembly 4 pushes the molten plastic into the communicating cavity 14 and all the through holes 13 through the feeding pipe 15, and finally flows into the gap between the protruding rod 12 and the cavity 10 through the through holes 13, completing the injection molding work.

[0039] In this embodiment, the cooling assembly 5 includes a heat exchange tube 16, an insulation box 1 18, a two-way pump 19 and an insulation box 2 20. The heat exchange tube 16 is fixedly connected to the inner wall of the mold 2 3, and the insulation box 1 18, the two-way pump 19 and the insulation box 2 20 are all fixedly connected to the outer wall of one side of the bracket 1.

[0040] The two ends of the heat exchange tube 16 are connected to the insulation box 18 and the insulation box 2 20 through hose 1 17 and hose 2 21 respectively, and the two ends of the two-way pump 19 are connected to the insulation box 18 and the insulation box 2 20 respectively, and the insulation box 18 and the insulation box 2 20 are filled with heat exchange oil.

[0041] During injection molding, the two-way pump 19 is started to transport the heat exchange oil from the insulation box 1 18 to the insulation box 2 20. When the heat exchange oil passes through the heat exchange tube 16, it absorbs the heat of the mold 1 2 and the mold 2 3, thereby realizing the injection molding cooling of the reaction cup and facilitating the subsequent demolding. When the injection molding is completed, the two-way pump 19 is started to transport the heat exchange oil from the insulation box 2 20 to the insulation box 1 18. When the heat exchange oil passes through the heat exchange tube 16, the mold 2 3 can be preheated.

[0042] By providing the heat exchange tube 16, the insulation box 1 18, the bidirectional pump 19, and the insulation box 2 20, the bidirectional pump 19 can be used to transport the heat exchange oil in both directions, thereby cooling the mold 1 2 and the mold 2 3 during injection molding, which facilitates the injection molding of the reaction cup. After the injection molding is completed, the mold 2 3 can be preheated to prevent the subsequent plastic from being cooled and solidified when entering the mold 2 3, affecting the injection molding process.

[0043] In this embodiment, the driving assembly includes a motor 22, a guide rod 23 and a screw rod 24. The motor 22 is fixed to the outer wall of the bracket 1 by bolts, and the output shaft of the motor 22 is fixedly connected to one end of the screw rod 24 through a coupling.

[0044] The guide rod 23 is fixed to the inner wall of the bracket 1, and the guide rod 23 is rotatably connected to the inner wall of the bracket 1. The mold 1 2 is slidably fitted to the outer wall of the guide rod 23, and the mold 1 2 is connected to the outer wall of the screw rod 24 through a thread. The mold 2 3 is movably fitted to the guide rod 23 and the outer wall of the screw rod 24.

[0045] The motor 22 is started to drive the screw 24 to rotate, and the screw 24 drives the mold 1 2 to move linearly. When the mold 1 2 and the mold 2 3 are fitted together, the screw 24 drives the mold 2 3 to move together. Example 2

[0046] A reaction cup injection molding device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-7 As shown:

[0047] The feeding assembly 4 includes a second feeding pipe 25, a transition box 26 and a heating barrel 29. The second feeding pipe 25 contacts and cooperates with the first feeding pipe 15. The second feeding pipe 25 slides on the inner wall of the transition box 26 through the piston 32. The transition box 26 and the heating barrel 29 are fixed to the outer walls on both sides of the bracket 1 by bolts.

[0048] The top of the transition box 26 is fixed and connected to a U-shaped tube 28, the other end of the U-shaped tube 28 passes through the heating barrel 29, and the inner walls of the feeding pipe 25 and the U-shaped tube 28 are respectively fixed with a one-way valve 2 30 and a one-way valve 1 27.

[0049] One side of the piston 32 is buckled with a second spring 31 , and the other end of the second spring 31 is buckled with the inner wall of the transition box 26 .

[0050] When mold 2 (3) moves, it squeezes feed pipe 2 (25) and piston 32 through feed pipe 1 (15), allowing the molten plastic in the inner cavity of transition box 26 to enter feed pipe 2 (25) through one-way valve 2 (30), and then enter the interior of mold 2 (3) through feed pipe 1 (15), and then cool and form. When mold 1 (2) is reset, spring 2 (31) pulls piston 32 back to its original position, generating negative pressure in the inner cavity of transition box 26, and the molten plastic in heating barrel 29 is sucked back into transition box 26 through U-shaped tube 28, completing a cycle.

[0051] By providing components such as a transition box 26, a one-way valve 1 27, a one-way valve 2 30, and a piston 32, suction-type loading is achieved by utilizing the reciprocating motion of the piston 32. The reciprocating motion of the piston 32 is achieved by the motion of the mold 2 3, thereby achieving synchronous loading and mold opening and closing, reducing the layout of the power source and increasing synchronous linkage.

[0052] Working principle: When the device is in use, the motor 22 is started to drive the screw rod 24 to rotate, and the screw rod 24 drives the mold 1-2 to move linearly. When the push rod 11 contacts the outer wall of the mold 2-3, the mold 1-2 continues to move, so that the push rod 11 drives the ejector rod 9 and the slide plate 7 to move inward, and the spring 1-8 is elastically deformed under the force. When the mold 1-2 is fitted with the mold 2-3, it drives the mold 2-3 to move together. At this time, the protruding rod 12 is located in the cavity 10. When the mold 2-3 moves with the mold 1-2, it will squeeze the feed pipe 2-25 and the piston 32 through the feed pipe 1-15, and the molten plastic in the inner cavity of the transition box 26 enters the feed pipe 2-25 through the one-way valve 2-30, and then enters the interior of the mold 2-3 through the feed pipe 1-15 , and finally flows from the through hole 13 to the gap between the cavity 10 and the protruding rod 12, and then the two-way pump 19 is started to transport the heat exchange oil from the insulation box 18 to the insulation box 2 20. When the heat exchange oil passes through the heat exchange tube 16, it absorbs the heat of the mold 1 2 and the mold 2 3 to realize the injection molding of the reaction cup; after the injection molding is completed, the mold 1 2 is reset, and the spring 1 8 uses its own elasticity to push the slide plate 7, the push rod 9 and the push rod 11 to move outward and reset. The push rod 9 pushes the reaction cup in the cavity 10 to realize the unloading. At the same time, the spring 2 31 pulls the piston 32 to reset, and the inner cavity of the transition box 26 generates negative pressure. The molten plastic in the heating barrel 29 is sucked into the transition box 26 again through the U-shaped tube 28, completing a cycle.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
