Description
Technical Field
[0001] This utility model relates to the field of mold ejection technology, specifically a novel composite inclined ejection mechanism. Background Technology
[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of colors and shapes (from simple to complex), and sizes ranging from large to small. It also produces precise dimensions, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.
[0003] When products from injection molds are ejected, they are usually ejected using a slanted ejector. The slanted ejector, also known as a slanted pin or slanted ejector, is mainly used to solve the demolding problem of the undercut structure inside the injection molded product. It uses a side core-pulling mechanism driven by the ejector plate to convert vertical motion into horizontal motion, thereby separating the undercut part. It is suitable for simple undercut molding scenarios.
[0004] Existing inclined ejector mechanisms have a single ejection direction and a complex inclined ejector structure, making them difficult to adapt to different machine tools. In addition, the inclined ejector has a short service life. Therefore, they do not meet the current requirements. To address this, we propose a new type of composite inclined ejector mechanism. Utility Model Content
[0005] The purpose of this utility model is to provide a novel composite inclined ejector mechanism to solve the problems mentioned in the background art, such as the single ejection direction of the inclined ejector mechanism, the complex inclined ejector structure, the difficulty in adapting to different machine tools, and the low service life of the inclined ejector.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel composite inclined ejector mechanism, comprising a rear mold core, the top of which is provided with a processed product, the surface of which is provided with an arc-shaped retaining groove, a first inclined ejector, a second inclined ejector, and a third inclined ejector movably mounted on the surface of the rear mold core near the arc-shaped retaining groove, the first inclined ejector, the second inclined ejector, and the third inclined ejector fitting together to form a trapezoidal shape, an inclined ejector rod fixedly mounted at the bottom of each of the first inclined ejector, the second inclined ejector, and the third inclined ejector, a circular insert fixedly mounted at the bottom of each of the inclined ejector rods, a T-shaped sliding seat hinged to the bottom of each of the circular inserts, an inclined ejector seat movably mounted at the bottom of each of the T-shaped sliding seats, and an inclined ejector buckle fixedly mounted on the side of each of the first inclined ejector, the second inclined ejector, and the third inclined ejector near the arc-shaped retaining groove, the inclined ejector buckle movably engaging inside the arc-shaped retaining groove.
[0007] Preferably, an inclined guide block is movably mounted on the outer surface of the inclined push rod, and the surface of the inclined guide block is provided with three inclined through holes, all of which are through the interior of the inclined push rod.
[0008] Preferably, each of the inclined top seats is provided with a T-shaped sliding groove at its top, and the T-shaped sliding seat slides into the interior of the T-shaped sliding groove.
[0009] Preferably, both ends of the inner wall surface of the T-shaped sliding groove are movably mounted with blocking plates, and the inside of the inclined top seat is provided with spring grooves near the blocking plates, and the blocking plates are slidably inserted into the inside of the spring grooves.
[0010] Preferably, a compression spring is movably installed between the blocking plate and the inside of the spring groove, with one end of the compression spring connected to the blocking plate and the other end of the compression spring connected to the inner wall of the spring groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the cooperation of three inclined ejectors, enables the device to, when the product injection molding is completed and demolding is required, first open the front mold core from the surface of the rear mold core, leaving the product on the surface of the rear mold core. Then, the three inclined ejector seats push the T-shaped sliding seat and the inclined ejector rod along the inclined through hole on the surface of the inclined ejector guide block, thereby pushing the first, second, and third inclined ejectors out in three directions. In turn, the inclined ejectors push the product through the arc-shaped groove on the surface of the product, thus ejecting the product from the surface of the rear mold core. This makes it easy for the robot to pick up and transport the product to the subsequent processing position. This inclined ejector structure is simple, increases the production efficiency of the mold, and reduces the size and cost of the mold.
[0013] 2. This utility model, through the cooperation of the T-shaped sliding seat and the circular insert, allows the device to reduce a large amount of ejection resistance of the inclined ejector by utilizing the rotational cooperation between the circular insert and the T-shaped sliding seat during use, thereby improving the service life of the mold.
[0014] 3. This utility model, through the cooperation of the blocking plate and the compression spring, can prevent the T-shaped sliding seat from sliding and falling off in the T-shaped sliding groove when the device is in use. At the same time, when it is necessary to maintain, replace or clean the T-shaped sliding seat and the circular insert, the blocking plate can be pressed to retract into the spring groove, and then the T-shaped sliding seat can be slid outward to complete the quick disassembly of the T-shaped sliding seat, which facilitates the use of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1 to 5 This utility model provides an embodiment of a novel composite inclined ejector mechanism, comprising a rear mold core 1, a processed product 2 at the top of the rear mold core 1, an arc-shaped groove 12 on the surface of the processed product 2, a first inclined ejector 3, a second inclined ejector 4, and a third inclined ejector 5 movably mounted on the surface of the rear mold core 1 near the arc-shaped groove 12, the first inclined ejector 3, the second inclined ejector 4, and the third inclined ejector 5 fitting together to form a trapezoidal shape, an inclined ejector rod 6 fixedly mounted at the bottom of the first inclined ejector 3, the second inclined ejector 4, and the third inclined ejector 5, a circular insert 16 fixedly mounted at the bottom of the inclined ejector rod 6, a T-shaped sliding seat 7 hinged to the bottom of the circular insert 16, an inclined ejector seat 8 movably mounted at the bottom of the T-shaped sliding seat 7, and an inclined ejector buckle 11 fixedly mounted on the side of the first inclined ejector 3, the second inclined ejector 4, and the third inclined ejector 5 near the arc-shaped groove 12, the inclined ejector buckle 11 movably engaging inside the arc-shaped groove 12.
[0023] By coordinating the three angled ejectors, when the product 2 is injection molded and needs to be ejected, the front mold core is first opened from the surface of the rear mold core 1, leaving the product 2 on the surface of the rear mold core 1. Then, the three angled ejector seats 8 push the T-shaped sliding seat 7 and the angled ejector rod 6 along the angled through hole on the surface of the angled ejector guide block 10, thereby pushing the first angled ejector 3, the second angled ejector 4, and the third angled ejector 5 out in three directions. This pushes the product 2 through the angled ejector buckle 11 into the arc-shaped buckle groove 12 on the surface of the product 2, thus ejecting the product 2 from the surface of the rear mold core 1. This makes it easy for the robot to pick up and transport the product 2 to the subsequent processing position. This angled ejector structure is simple, increases the production efficiency of the mold, and reduces the size and cost of the mold.
[0024] An inclined guide block 10 is movably installed on the outer surface of the inclined push rod 6. The surface of the inclined guide block 10 is provided with three inclined through holes, and the inclined push rod 6 passes through the interior of each inclined through hole.
[0025] By using the T-shaped sliding seat 7 and the circular insert 16, the device can reduce the ejection resistance of the inclined ejector by rotating the circular insert 16 with the T-shaped sliding seat 7 during use, thereby improving the service life of the mold.
[0026] The top of each inclined top seat 8 is provided with a T-shaped sliding groove 13, and the T-shaped sliding seat 7 slides into the interior of the T-shaped sliding groove 13.
[0027] Both ends of the inner wall surface of the T-shaped sliding groove 13 are movably installed with baffle plates 9. The inside of the inclined top seat 8 is provided with spring grooves 14 near the baffle plates 9. The baffle plates 9 are slidably inserted into the inside of the spring grooves 14.
[0028] With the cooperation of the baffle plate 9 and the compression spring 15, when the device is in use, the baffle plate 9 can block the T-shaped sliding seat 7, preventing it from sliding and falling off in the T-shaped sliding groove 13 when it is pushed out. At the same time, when it is necessary to maintain, replace or clean the T-shaped sliding seat 7 and the circular insert 16, the baffle plate 9 can be pressed to retract into the spring groove 14, and then the T-shaped sliding seat 7 can be slid outward to complete the quick disassembly of the T-shaped sliding seat 7, which facilitates the use of the device.
[0029] A compression spring 15 is movably installed between the baffle plate 9 and the inside of the spring groove 14. One end of the compression spring 15 is connected to the baffle plate 9, and the other end of the compression spring 15 is connected to the inner wall of the spring groove 14.
[0030] When this novel composite inclined ejector mechanism is in use, after the injection molding of the processed product 2 is completed, and it is necessary to eject the processed product 2 from the mold, the front mold core is first opened from the surface of the rear mold core 1. At this time, the processed product 2 will remain on the surface of the rear mold core 1. Then, the three inclined ejector seats 8 push the T-shaped sliding seat 7 and the inclined ejector rod 6 to move along the inclined through hole on the surface of the inclined ejector guide block 10, thereby pushing the first inclined ejector 3, the second inclined ejector 4 and the third inclined ejector 5 to be ejected in three directions. Then, through the inclined ejector buckle 11, it pushes the arc-shaped buckle groove 12 on the surface of the processed product 2, thereby ejecting the processed product 2 from the surface of the rear mold core 1. This makes it easy for the robot to clamp and transport the processed product 2 to the subsequent processing position. This inclined ejector structure is simple, increases the production efficiency of the mold, and reduces the size of the mold and the cost of the mold.
[0031] The device can reduce a large amount of ejection resistance of the inclined ejector by utilizing the rotational engagement of the circular insert 16 and the T-shaped sliding seat 7, thereby improving the service life of the mold.
[0032] The T-shaped sliding seat 7 can be blocked by the baffle plate 9 to prevent it from sliding and falling off in the T-shaped sliding groove 13 when it is pushed out. At the same time, when it is necessary to maintain, replace or clean the T-shaped sliding seat 7 and the circular insert 16, the baffle plate 9 can be pressed to retract into the spring groove 14, and then the T-shaped sliding seat 7 can be slid outward to complete the quick disassembly of the T-shaped sliding seat 7, which facilitates the use of the device.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
