Description

Technical Field

[0001] The invention relates to the technical field of equipment related to mold processing, and in particular to an asymmetric inner sleeve skeleton feeder. Background Art

[0002] In the vulcanization process of rubber parts with inner sleeve skeletons, a one-mold-multiple-cavity processing method is generally used to improve production efficiency. Some of the inner sleeve skeletons in existing products are asymmetrical structures, which need to be manually distinguished before being placed in the mold cavity. The staff distinguishes the front and back and manually places them in the mold, which is relatively inefficient. In general, in order to improve work efficiency, the staff sometimes puts the inner sleeve skeleton upside down, resulting in damage to the vulcanization mold and production of defective products. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes an asymmetric inner sleeve skeleton feeder.

[0004] The present invention proposes an asymmetric inner sleeve skeleton feeder, which is used to place an asymmetric inner sleeve skeleton into a mold, and comprises an upper plate and a lower plate arranged below the upper plate, wherein the lower plate is slidably mounted on the mold and can slide relative to the upper plate, the upper plate is provided with a feeding hole, the lower plate is provided with a leakage hole and a supporting surface, the lower plate has a placing station and a discharging station, when the lower plate is located at the placing station, the supporting surface is opposite to the feeding hole, and when the lower plate is at the discharging station, the leakage hole is opposite to the feeding hole;

[0005] A positioning component is provided between the upper plate and the mold. When the lower plate is pulled to slide relative to the mold, the upper plate is positioned horizontally relative to the mold through the arrangement of the positioning component.

[0006] During use, when the mold is processing the product, the inner sleeve skeleton can be placed in the loading hole of the loading part first. At this time, the lower plate is in the placement position, and one inner sleeve skeleton is placed in one loading hole. When the mold is opened to take out the product, the discharge part with the inner sleeve skeleton is placed on the mold, and then the lower plate is pulled under the action of external force to make the lower plate in the discharge position, so that the inner sleeve skeleton is discharged from the leakage hole to the cavity of the mold, thereby increasing the feeding efficiency of the inner sleeve skeleton.

[0007] Preferably, at least two groups of the feeding holes and the leakage holes are provided, and one group of the leakage holes corresponds to one group of the feeding holes.

[0008] Preferably, the positioning assembly comprises at least two positioning pins, and the at least two positioning pins are circumferentially distributed on the upper plate, and the bottoms of the positioning pins are connected to the mold.

[0009] Preferably, a positioning hole is opened on the mold, and the positioning hole matches the lower end of the positioning pin.

[0010] Preferably, a sliding hole is opened on the mold, the positioning pin passes through the sliding hole, and when the lower plate slides relative to the upper plate and the mold, the positioning pin slides in the sliding hole.

[0011] Preferably, the positioning pin has an upper clamping surface and a lower clamping surface, the upper clamping surface abuts against the upper surface of the lower plate, the lower clamping surface abuts against the bottom of the lower plate, and the distance between the lower clamping surface and the upper clamping surface is adjustable.

[0012] Preferably, the positioning pin includes a connected supporting part and a sliding part, the outer diameter of the sliding part is smaller than the outer diameter of the supporting part, the supporting part is connected to the loading plate, the sliding part is located in the sliding hole, the sliding part and the supporting part form the upper clamping surface, the sliding part has a part extending out of the sliding hole, and a clamping piece is installed outside the sliding part extending out of the sliding hole, the upper surface of the clamping piece is the lower clamping surface, and the distance from the clamping piece to the upper clamping surface is adjustable.

[0013] Preferably, it further comprises a vertical limiter, and when the lower plate is in the blanking station, the vertical limiter prevents the lower plate from moving in the vertical direction relative to the mold.

[0014] Preferably, the vertical limit member includes a T-shaped clip installed on the lower plate, the outer diameter of the lower end of the T-shaped clip is larger than the outer diameter of the end of the T-shaped clip close to the lower plate, and a T-shaped slot and a feed slot connected to the T-shaped slot are opened on the mold. When the lower plate is in the placement position, the T-shaped clip is located in the feed slot, and when the lower plate is pulled, the T-shaped clip is located in the T-shaped slot, thereby preventing the lower plate from moving in the vertical direction relative to the mold.

[0015] Preferably, a handle is provided on one side of the lower plate.

[0016] In the present invention, the proposed asymmetric inner sleeve skeleton feeder can place the inner sleeve skeleton in the feeding hole of the feeder during the process of mold processing products. When the mold processing products are completed, the inner sleeve skeleton on the upper plate is moved through the leakage hole to the cavity of the mold by placing the feeding piece on the mold and pulling the lower plate, thereby increasing work efficiency and giving the staff sufficient time to place the inner sleeve skeleton.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figure 1-Figure 6 An asymmetric inner sleeve skeleton feeder shown is used for feeding a rubber mold 5 with an inner sleeve skeleton. Preferably, the inner sleeve skeleton is an asymmetric structure, which can realize the simultaneous feeding of multiple inner sleeve skeletons on the mold 5;

[0029] The feeder comprises an upper plate 1, a lower plate 2 is provided below the upper plate 1, preferably, the lower plate 2 is parallel to the upper plate 1, the lower plate 2 is horizontally slidably installed on the mold 5, the lower plate 2 can slide relative to the upper plate 1, a material storage space is formed between the upper plate 1 and the lower plate 2, a material leakage hole 20 and a support surface located on one side of the material leakage hole 20 are provided on the lower plate 2, and a loading hole 10 is provided on the upper plate 1. When the feeder is placed on the mold 5, the loading hole 10 is opposite to the cavity on the mold 5, and the loading hole 10 is opposite to the support surface (at this time, the lower plate 2 is in the placing position), and the sliding lower plate 2 realizes that the material leakage hole 20 is opposite to the loading hole 10, and the inner sleeve skeleton in the loading hole 10 falls into the cavity of the mold 5 through the material leakage hole 20 (at this time, the upper plate 1 is in the unloading position);

[0030] Specifically, when feeding the inner sleeve skeleton whose cavity is circumferentially distributed in the mold 5, at least two groups of feeding holes 10 are provided, and at least two groups of feeding holes 10 correspond to the cavities on the mold 5; multiple leakage holes 20 are provided, and one leakage hole 20 corresponds to one feeding hole 10;

[0031] There is a positioning assembly between the upper plate 1 and the mold 5. When the feeder is placed on the mold 5, the positioning assembly limits the five degrees of freedom of the upper plate 1 except for the up and down directions. That is, when the feeder is installed on the mold 5, the upper plate 1 can only move in the vertical direction relative to the mold 5 through the setting of the positioning assembly. Preferably, the positioning assembly has a limiting structure 9 to limit the minimum distance between the upper plate 1 and the mold 5; specifically, the lower plate 2 can slide relative to the positioning assembly.

[0032] Preferably, in order to facilitate pulling the lower plate 2 , a handle 3 is provided on one side of the lower plate 2 .

[0033] Specifically, the positioning assembly includes at least two positioning pins 4, which are circumferentially distributed on the upper plate 1. The upper ends of the positioning pins 4 are connected to the upper plate 1. A positioning hole 50 is opened on the mold 5, and the positioning hole 50 matches the lower end of the positioning pin 4. A sliding hole 21 is opened on the lower plate 2. The positioning pin 4 passes through the sliding hole 21 and is connected to the positioning hole 50 on the mold 5. When the lower plate 2 is slid, the positioning pin 4 slides in the sliding hole 21.

[0034] Preferably, the upper end of the locating pin 4 can be detachably mounted on the upper plate 1, and the upper end of the locating pin 4 can be mounted on the upper plate 1 by threading, or the locating pin 4 can be mounted on the upper plate 1 by clamping, and in order to prevent the lower plate 2 of the loading piece from sliding relative to the upper plate 1 when it is not subjected to a certain pulling force, the locating pin 4 has an upper clamping surface 40 and a lower clamping surface 41, the upper clamping surface 40 is in contact with the upper surface of the lower plate 2, the lower clamping surface 41 is in contact with the lower surface of the lower plate 2, and the distance between the lower clamping surface 41 and the upper clamping surface 40 is adjustable. Specifically, the locating pin 4 includes a supporting portion 42 and a sliding portion 43, the outer diameter of the sliding portion 43 is smaller than the outer diameter of the supporting portion 42, the supporting portion 42 is connected to the loading plate, and the sliding portion 43 is located in the sliding hole 21 An upper clamping surface 40 is formed between the sliding portion 43 and the supporting portion 42, and the sliding portion 43 has a portion extending out of the sliding hole 21. The sliding portion 43 extending out of the sliding hole 21 is provided with a clamping member 6 by means of a thread. The upper surface of the clamping member 6 forms a lower clamping surface 41. The clamping member 6 is rotated to adjust the distance between the upper clamping surface 40 and the lower clamping surface 41, thereby realizing the friction force between the locating pin 4 and the lower plate 2, thereby avoiding the lower plate 2 from sliding relative to the upper plate 1 under the action of a small force, and avoiding the loading of the material during the placement of the inner sleeve frame or the movement of the loading member. Of course, those skilled in the art may also adopt other card connections or other methods of connection between the clamping member 6 and the sliding portion 43 as long as the distance from the clamping member 6 to the upper clamping surface 40 can be adjusted.

[0035] As shown in the figure, four groups of positioning pins 4 are provided, and the four groups of positioning pins 4 are circumferentially distributed with the center line of the distribution of the plurality of feeding holes 10 as the axis.

[0036] Preferably, the sliding hole 21 is a waist-shaped hole. When the positioning pin 4 slides to the first side of the waist-shaped hole, the lower plate 2 is in the placement position. When the positioning pin 4 slides to the second side of the waist-shaped hole opposite to the first side, the lower plate 2 is in the unloading position.

[0037] Preferably, in order to further limit the position of the inner sleeve frame, a sleeve 7 is also included. A sleeve 7 is installed in each of the loading holes 10, and the inner lining frame is installed in the sleeve 7. Preferably, there is a sliding gap from the bottom of the sleeve 7 to the upper surface of the lower plate 2.

[0038] Of course, the inner wall of the sleeve 7 may have an elastic clamp, and the inner sleeve frame arranged in the sleeve 7 can only be separated from the sleeve 7 under the action of external force.

[0039] In some embodiments, preferably, in order to achieve that the lower plate 2 is separated from the mold 5 in the vertical direction when the lower plate 2 is in the unloading position, a vertical limiter 8 is also included to prevent the lower plate 2 from moving in the vertical direction relative to the mold 5 when the lower plate 2 is in the unloading position.

[0040] In some embodiments, preferably, the vertical limit member 8 includes a T-shaped clip installed on the lower plate 2, the outer diameter of the lower end of the T-shaped clip is larger than the outer diameter of the end of the T-shaped clip close to the lower plate 2, and the mold 5 is provided with a T-shaped slot 51 and a feed slot 52 connected to the T-shaped slot 51, and the aperture of the feed slot 52 is not less than the maximum outer diameter of the T-shaped clip. When the lower plate 2 is in the placement position, the T-shaped clip is located in the feed slot 52, and when the lower plate 2 is pulled, the T-shaped clip is located in the T-shaped slot 51, thereby preventing the lower plate 2 from moving in the vertical direction relative to the mold 5.

[0041] like Figure 7 As shown, a hole is opened in the inner sleeve frame, and a limiting groove is opened at one end of the inner sleeve frame (so the inner sleeve frame is an asymmetric structure), the limiting groove is connected with the hole, the aperture of the limiting groove is larger than the aperture of the hole and the limiting groove is coaxial with the hole, and when the inner sleeve frame is placed upright, the limiting groove is located at the bottom, and the lower template of the mold 5 is provided with a limiting structure 9, the limiting structure 9 has a part matching with the limiting groove and also has a part extending to the hole, and the limiting structure 9 has an annular plane that conflicts with the limiting groove. If the inner sleeve frame is placed correctly, that is, the limiting groove fixed by the inner sleeve is at the bottom, when the limiting groove matches the limiting structure 9 during the blanking process, the inner sleeve frame is separated from the lower plate, and the lower plate 2 can be pulled to the original position to separate the T-shaped clamping piece and the T-shaped groove 51 to the feeding groove 52, and then the lower plate 2 can be moved upward to separate the feeder from the mold 5;

[0042] If the inner sleeve frame is placed upside down (the limit groove of the inner sleeve frame is located at the top), when the inner sleeve frame is blanking, Figure 8 As shown, the annular plane of the limiting structure 9 contacts the end face of the inner sleeve skeleton, so that the upper part of the inner sleeve skeleton has a portion located in the lower plate leakage hole 20, and the lower plate 2 cannot be pulled outward, then the T-shaped clip of the lower plate 2 cannot be separated from the T-shaped slot 51, and the lower plate 2 cannot be moved upward, and the feeder cannot be separated from the mold 5. The staff is required to check whether there is an inner sleeve skeleton placed upside down and correct it before removing the feeder from the mold 5, to prevent the inner sleeve skeleton from being placed upside down, thereby increasing the yield rate of molded parts.
