[0001] The utility model relates to a demoulding device for an injection mold, in particular to a demoulding structure for an injection mold and an air conditioner. Background Art

[0002] At present, plastic molds on the market face a common problem in application: when there are undercuts on the non-open product surface in the demolding direction, the mold needs to use a lateral core pulling structure to remove these undercuts and complete the demolding process of the product. However, in many cases, the internal space of the product is limited and cannot accommodate the installation of the lateral core pulling device, which makes the lateral core pulling impossible.

[0003] This limitation not only affects the quality of the product, because the undercut cannot be smoothly removed, which may cause the product to be deformed or damaged, but also greatly increases the difficulty of the work. Operators need to spend more time and energy to solve this problem, which greatly reduces work efficiency.

[0004] In summary, solving the problem of lateral core pulling in plastic molds requires comprehensive consideration of mold design, special core pulling mechanism, production process and operating skills. Through continuous optimization and innovation, this problem can be overcome to improve product quality and work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an injection mold demoulding structure and an air conditioner, which realize the requirement that there is no lateral demoulding space for the undercut structure in the product.

[0006] The utility model solves the technical problem by adopting the following technical solution: an injection mold ejection structure, comprising a movable mold mechanism and a tilted ejection mechanism, wherein the movable mold mechanism comprises a movable mold insert, the tilted ejection mechanism comprises a tilted ejection rod, the top of the tilted ejection rod is connected with the tilted ejection insert, and the tilted ejection mechanism is connected to the movable mold insert.

[0007] As a further improvement of the utility model: the inclined ejector mechanism comprises an ejector plate and an ejector, and the ejector is fixed on the ejector plate.

[0008] As a further improvement of the utility model: the inclined ejector mechanism further comprises an inclined ejector rod, and the inclined ejector rod is movably connected to the movable mold mechanism.

[0011] As a further improvement of the utility model: it also includes a second pin, and the second inclined top insert is connected to the right side of the inclined top rod through the second pin.

[0012] As a further improvement of the utility model: it also includes an insert inner groove swinging surface, and the insert inner groove swinging surface is arranged on the inner wall of the movable mold insert.

[0013] As a further improvement of the utility model: it also includes a clearance surface, and the first inclined top insert and the bottom of the second inclined top insert are movably connected to form the clearance surface.

[0014] As a further improvement of the utility model: it also includes a reset surface, and the reset surface is arranged inside the inclined ejector rod.

[0015] As another solution of the utility model: an air conditioner suitable for the injection mold demoulding structure.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the utility model discloses an injection mold demoulding structure and an air conditioner, which structure combines a movable mold mechanism and an inclined ejector mechanism to solve the problem of realizing demoulding of an undercut structure in a limited space.

[0017] Specifically, the movable mold mechanism includes a movable mold insert, which provides a stable foundation for the entire demoulding structure.

[0031] The inclined top insert comprises a first inclined top insert 3 and a second inclined top insert 4 . The first inclined top insert 3 is connected to the left side of the inclined top rod 5 , and the second inclined top insert 4 is connected to the right side of the inclined top rod 5 .

[0032] It also includes a first pin 6, and the first inclined top insert 3 is connected to the left side of the inclined top rod 5 through the first pin 6.

[0033] It also includes a second pin 61 , and the second inclined top insert 4 is connected to the right side of the inclined top rod 5 through the second pin 61 .

[0036] It also includes a reset surface 7, which is arranged inside the inclined ejector rod 5.

[0037] Working principle of the utility model: The operation process is as follows:

[0038] Injection molding stage: First, the molten plastic is injected into the mold to fill the mold cavity. Supported by the movable mold mechanism and the inclined ejector mechanism, the plastic is cooled and shaped in the mold.

[0039] Ejection stage: When the plastic is cooled and shaped, the injection molding machine will perform the ejection action. The ejection mechanism of the injection molding machine will push the movable mold insert and the inclined ejector mechanism connected to it. The inclined ejector rod starts to move, and drives the undercut part of the product to move along the predetermined trajectory through the inclined ejector insert.

[0040] Demolding of undercut structure: With the continuous movement of the lifter, the lifter insert pulls out the undercut structure in the product in an oblique direction. In this process, the first lifter insert and the second lifter insert work together to ensure the accuracy and stability of the demolding process through the precise positioning and guidance of the first pin and the second pin.

[0041] Reset stage: When the undercut structure is completely separated from the product, the injection molding machine will perform the reset action. The lift mechanism returns to the initial position under the action of the reset spring or reset mechanism, ready for the next injection cycle.

[0042] During the entire operation, the design of the swing surface and the reset surface also plays an important role. The swing surface is responsible for guiding the movement trajectory of the lift mechanism to ensure the smooth demoulding process; while the reset surface is responsible for guiding the lift mechanism back to the correct position during the reset stage.

[0043] This demoulding structure design makes full use of the structure of the mold itself, and realizes the demoulding of the undercut structure in a limited space through the designed inclined ejector rod, inclined ejector insert, pin and other components, as well as the ejection and reset actions of the injection molding machine. This design not only simplifies the mold structure and improves the reliability of the mold, but also significantly improves production efficiency and reduces labor intensity, bringing substantial improvements to injection molding production.

[0044] Implementation case 1:

[0045] The injection molding demolding structure is a key link in the injection molding process. It ensures that the plastic part can be smoothly separated from the mold and maintains the durability of the mold. Traditionally, the oblique pin structure is widely used in injection molding demolding, but this method needs to meet two basic conditions: the strength of the oblique pin structure and the lateral displacement diagram that accurately represents the position and structural relationship of the undercut demolding in the mold.

[0046] However, in actual production, especially when dealing with plastic parts with complex structures, the traditional oblique pin structure may encounter challenges. For example, when there is a product buckle structure on the inner wall of the movable mold, these buckle structures form undercuts in the ejection direction of the mold, making it difficult for the traditional oblique pin structure to meet the ejection requirements. This is because these structural spaces are often insufficient to support an oblique pin of sufficient strength, and they also cannot provide sufficient space for lateral core pulling and displacement.

[0047] Therefore, this new undercut mold structure is designed:

[0048] An injection mold demoulding structure includes a movable mold mechanism and a tilting ejector mechanism, wherein the movable mold mechanism includes a movable mold insert 2, and the tilting ejector mechanism includes a tilting ejector rod 5. The top of the tilting ejector rod 5 is connected to the tilting ejector insert, and the tilting ejector mechanism is connected to the movable mold insert 2. During the injection molding process, the movable mold insert 2 plays a role in supporting and fixing the plastic part. Ensure that the position of the plastic part in the mold is stable for subsequent demoulding operations. When the injection molding is completed and cooled to an appropriate temperature, the demoulding process begins. The tilting ejector mechanism provides a lateral core pulling force through the tilting ejector rod 5. The top of the tilting ejector rod 5 is connected to the tilting ejector insert, and the tilting ejector insert applies force in the demoulding direction so that the undercut structure in the plastic part is smoothly pulled out of the mold. Under the action of the tilting ejector mechanism, the plastic part gradually detaches from the mold. The operator can assist in removing the plastic part and check its quality and integrity.

[0049] The inclined ejector mechanism comprises an ejector plate 10 and an ejector pin 11 , and the ejector pin 11 is fixed on the ejector plate 10 .

[0050] The inclined ejector mechanism further comprises an inclined ejector rod 5, and the inclined ejector rod 5 is movably connected to the movable mold mechanism.

[0051] The inclined top insert comprises a first inclined top insert 3 and a second inclined top insert 4 . The first inclined top insert 3 is connected to the left side of the inclined top rod 5 , and the second inclined top insert 4 is connected to the right side of the inclined top rod 5 .

[0052] It also includes a first pin 6, and the first inclined top insert 3 is connected to the left side of the inclined top rod 5 through the first pin 6.

[0053] It also includes a second pin 61 , and the second inclined top insert 4 is connected to the right side of the inclined top rod 5 through the second pin 61 .

[0054] It also includes an insert inner groove swinging surface 8, and the insert inner groove swinging surface 8 is arranged on the inner wall of the movable mold insert 2.

[0055] It also includes a clearance surface 9 , and the first inclined top insert 3 and the second inclined top insert 4 are movably connected at the bottom to form the clearance surface 9 .

[0056] It also includes a reset surface 7, which is arranged inside the inclined ejector rod 5.

[0057] Combination Figure 1-3 After the mold is opened, the injection molding machine ejects, and the ejector pin 11 and the inclined ejector rod 5 installed on the ejector plate 10 are driven to eject in the Z direction. The first inclined ejector insert 3 and the second inclined ejector insert 4 installed on the inclined ejector rod 5 through the pin are also ejected out of the mold cavity along with the inclined ejector rod 5. When the movement stroke of the first inclined ejector insert 3 and the second inclined ejector insert 4 reaches the set stroke, the raised swing surfaces of the first inclined ejector insert 3 and the second inclined ejector insert 4 will touch the swing surface 8 in the insert groove, and the swing surface 8 is semi-cylindrical; if the ejection continues at this time, The first inclined top insert 3 and the second inclined top insert 4 are respectively pressed by the swing surface 8, and the first inclined top insert 3 and the second inclined top insert 4 will deflect along the swing surface 8 around the pin, and the heads of the first inclined top insert 3 and the second inclined top insert 4 (relative to the pin end) will open. When the set ejection height is consistent with the Z-direction difference of the highest point of the swing surface 8, the distance between the heads of the first inclined top insert 3 and the second inclined top insert 4 is the largest, and the product buckle is separated from the inclined top insert, and the release is completed, and the product can be taken out;

[0058] Mold reset: When the injection molding machine ejects and retracts, the first inclined top insert 3 and the second inclined top insert 4 will retract along with the inclined top rod 5 until the ejector plate 11 retracts to the bottom. At this time, the first inclined top insert 3 and the second inclined top insert 4 will be restricted by the inclined top groove reset surface 7 (the angle between the reset surface slope and the Z-axis direction is 30 degrees) when they retract. The opened heads of the first inclined top insert 3 and the second inclined top insert 4 will rotate around the pin in the restoring direction due to the contact pressure of the restricted inclined surface, and finally return to the initial state;

[0059] In summary, an injection mold demoulding structure makes full use of the mold's own structure and innovatively designs the inclined ejector rod, the first inclined ejector insert, the second inclined ejector insert, the first pin, the second pin, the swing surface, the reset surface, etc. The product is inverted through the ejection and reset actions of the injection molding machine, and the structures and actions of these mechanisms cooperate with each other to achieve the demoulding of the inverted structure in the limited space of the product; the designed mold structure is reasonable, simple and practical, which improves the mold reliability and production efficiency and meets the product performance.

[0060] As another embodiment of the present invention: an air conditioner suitable for the injection mold demoulding structure described in the implementation case 1.

[0061] The main function of the utility model is to provide an injection mold demoulding structure and an air conditioner, which solves the problem that the product has an undercut structure that can only be demoulded by lateral core pulling, and at the same time solves the disadvantage that the undercut structure does not have enough lateral core pulling demoulding space in the product.
