Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a demolding auxiliary device for injection molds of massage chairs. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are commonly used molding equipment that uses the mold cavity of a plastic mold to mold thermoplastic or thermosetting plastics into various shapes of plastic products. In the actual use of injection molding machines, demolding is a crucial step in ensuring the high-quality molding of the plastic parts. Most existing injection molds use a front and rear mold design. During the injection molding of massage chair accessories, there is a risk that the injection molded part may accidentally fall after complete demolding during mold opening. It may not fall accurately and undamaged into the injection molded part collection area or be received by the operator, making the injection molded part prone to damage and affecting the processing quality. Utility Model Content

[0003] The purpose of this utility model is to provide a demolding auxiliary device for injection molds of massage chairs, in order to solve the problem that injection molded parts may fall accidentally after complete demolding when the existing injection molds are opened, and cannot fall accurately and undamaged into the injection molded parts collection area or be received by the operator, which makes the injection molded parts easy to be damaged and affects the processing quality.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a demolding auxiliary device for a massage chair injection mold, comprising:

[0005] The front mold, on which a casting cavity is provided;

[0006] The rear mold has a movable cavity inside. One end face of the movable cavity extends to a connection port, and the other end face extends to a plurality of insertion holes. A plurality of internal channels are provided on the outside of the insertion holes, and the internal channels connect the movable cavity and the outer ends of the insertion holes.

[0007] The movable plate is slidably disposed in the movable cavity, and the connecting shaft on it passes through the connecting port and is connected to the linear drive device for opening and closing the mold. Several sealing rods in front of it are correspondingly and tightly slidably inserted into the insertion hole.

[0008] As a further description of the above technical solution:

[0009] Several of the inner channels are arranged at an angle and at intervals along the circumference of the insertion hole.

[0010] As a further description of the above technical solution:

[0011] A stripper plate is attached to the front of the rear mold via a connector, and a through hole corresponding to the insertion hole is provided through the stripper plate.

[0012] As a further description of the above technical solution:

[0018] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0019] When the mold release auxiliary device of this utility model opens the mold, the drive connecting shaft moves backward, simultaneously pulling the movable plate. The sealing rod disengages from the outer end of the injection molded part and the inner channel, allowing the movable cavity and the insertion hole to connect through the inner channel. A negative pressure is created inside, generating suction on the injection molded part at the initial stage of mold opening, preventing it from accidentally falling during demolding. Afterward, the connecting shaft continues to move backward. At this time, the movable plate moves to and abuts against the rear end of the movable cavity, moving together with the rear mold to open the mold. The injection molded part disengages from the mold cavity. During this process, the stripper plate is magnetically or elastically positioned on the rear mold. Finally, the stripper plate abuts against the rear end of the C-shaped baffle, is blocked, and disengages from the rear mold. This causes re-pressure within the insertion hole, reducing suction, and the injection molded part falls to the injection molded part collection area below. This assists in the demolding of massage chair accessories, preventing accidental drops during mold opening that could affect processing quality. Attached Figure Description

[0029] Please see Figure 1-4 This utility model provides a technical solution: a demolding auxiliary device for a massage chair injection mold, comprising:

[0030] Front mold 1, on which a casting cavity 2 is provided;

[0031] The rear mold 3 has a movable cavity 4 inside. One end face of the movable cavity 4 extends to a connection port 5, and the other end face extends to a plurality of insertion holes 6. A plurality of inner channels 7 are provided on the outside of the insertion holes 6, and the inner channels 7 connect the outer ends of the movable cavity 4 and the insertion holes 6.

[0032] The movable plate 8 is slidably disposed within the movable cavity 4. Its connecting shaft 9 passes through the connecting port 5 and engages with a linear drive device for opening and closing the mold. Several sealing rods 10 at its front are correspondingly and tightly slidably inserted into the insertion holes 6. The linear drive device can be a conventional mold opening and closing drive device such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder.

[0033] Several inner channels 7 are arranged at an angle and at intervals along the circumference of the insertion hole 6 to increase the suction force formed at the insertion hole 6 on the injection molded part 100 when the mold is opened.

[0034] The front of the rear mold 3 is fitted with a stripper plate 11 via a connector 12, and the stripper plate 11 has a through hole 14 corresponding to the insertion hole 6.

[0035] The connector 12 is an elastic element with one end positioned in the mounting groove 13 of the rear mold 3, and the other end positioned on the stripper plate 11. The connector 12 is a magnet magnetically connected to the stripper plate 11. This allows the stripper plate 11 to be stably positioned on the rear mold 3 in the early stage of mold opening by the spring force and magnetic attraction.

[0036] The front mold 1 has a C-shaped baffle 15 extending along the mold opening and closing direction on its side. The outer edge of the stripper plate 11 extends to the outer side of the rear mold 3 and is slidably disposed on the inner side of the C-shaped baffle 15. The end of the C-shaped baffle 15 blocks the stripper plate 11.

[0037] The working principle of the demolding auxiliary device for a massage chair injection mold in this embodiment includes: during injection molding, the mold closes, such as... Figure 1 In operating state one, during mold opening, the drive connecting shaft 9 moves backward, simultaneously pulling the movable plate 8. The sealing rod 10 disengages from the outer end of the injection molded part 100 and the inner channel 7, allowing the movable cavity 4 and the insertion hole 6 to connect through the inner channel 7. This creates a negative pressure inside, thus generating suction on the injection molded part 100 during the initial mold opening phase, preventing it from accidentally falling off during demolding. Figure 2 As shown, this is the second usage state; afterwards, the connecting shaft 9 continues to move backward. At this time, the movable plate 8 moves to and abuts against the rear end of the movable cavity 4, and moves together with the rear mold 3 to open the mold. The injection molded part 100 is separated from the mold cavity 2, as shown. Figure 3 In the third usage state, the stripper plate 11 is positioned on the rear mold 3 by magnetic attraction or elastic force. Finally, the stripper plate 11 abuts against the rear end of the C-shaped baffle 15, is blocked, and detaches from the rear mold 3. This causes the insertion hole 6 to be repressed, the attraction force to be insufficient, and the injection molded part 100 falls into the injection molded part collection area below. This can assist in the demolding of massage chair accessories during injection molding, preventing them from accidentally falling during mold opening and affecting the processing quality.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
