DETAILED DESCRIPTION
[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. 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.
[0021] Example 1
[0022] refer to Figures 1 to 4 The novel undercut stabilizer bar bushing described in this embodiment includes a flow channel plate 1, an upper template 2, a lifting frame assembly 3 and a lower template 4;
[0023] A plurality of connected mold cavities are provided on the upper mold plate 2, the lifting frame assembly 3 and the lower mold plate 4. A plurality of inserts 41 are installed on the lower mold plate 4. The insert 41 is located in the middle of the mold cavity. The insert 41 is provided with an anti-flash assembly 6 protruding toward the mold cavity. The anti-flash assembly 6 includes an upper guide edge 61 and a lower guide edge 62. The upper guide edge 61 is arranged around one end of the insert 41 close to the upper mold plate 2, and the lower guide edge 62 is arranged around one end of the insert 41 close to the lower mold plate 4. Both the insert 41 and the upper guide edge 61 are in contact and connected with the upper mold plate 2.
[0024] Preferably, both the upper guide edge 61 and the lower guide edge 62 are smooth arc surfaces convex toward the mold cavity.
[0025] An injection hole 11 is provided on the flow channel plate 1. During injection, rubber is injected from the injection hole 11 and flows evenly into each group of mold cavities. The insert 41 forms the inner hole of the stabilizer bar bushing. The upper guide edge 61 and the lower guide edge 62 form a slope around the opening of the inner hole of the stabilizer bar bushing.
[0026] The upper guide edge 61, the lower guide edge 62 and the insert 41 together form the inner hole mold of the stabilizer rod bushing, and the cross section of the inner hole is an I-shape.
[0027] The mold can be opened after the product is formed. The traditional stabilizer bar bushing is easy to flash at both ends of the stabilizer bar socket. By setting the upper guide edge 61 and the lower guide edge 62, the edge of the stabilizer bar socket is not easy to flash, and the bonding between the stabilizer bar socket and the stabilizer bar is not affected.
[0028] Side guide edges 21 are installed on one end of both sides of the upper template 2 close to the lifting frame assembly 3, and the side guide edges 21 are slidably connected to the lifting frame assembly 3.
[0029] The lifting frame assembly 3 includes a lifting frame 31, a pressing plate 32 and a Haver 33. Five groups of Haver 33 are installed in the middle of the lifting frame 31, wherein the middle group of Haver 33 is fixedly installed in the middle of the lifting frame 31, and two groups of Haver 33 are installed on both sides of the middle Haver 33, respectively. The Haver 33 on both sides is slidably connected to the lifting frame 31, and any two adjacent groups of Haver 33 form a complete lifting frame cavity, and the lifting frame cavity belongs to a part of the mold cavity located in the lifting frame assembly 3, and two groups of pressing plates 32 are installed on both sides of the lifting frame 31. The length direction of the pressing plate 32 is perpendicular to the length direction of the Haver 33, and the two sides of the length direction of the Haver 33 on both sides are slidably installed between the pressing plate 32 and the lifting frame 31. When demolding, the side guide edges 21 move with the upper template 2 to make way for the Haver 33 on both sides, and the pulling claws act on the Haver 33 to drive the Haver 33 to slide to both sides along the length direction of the pressing plate 32 to facilitate demolding; the side guide edges 21 play a guiding and limiting role.
[0030] It also includes an auxiliary component 5 for guiding and connecting the flow channel plate 1 and the upper template 2, the auxiliary component 5 includes a back-pull rod sleeve 55, four groups of back-pull rod sleeves 55 are respectively installed at the four corners of the upper template 2, and a group of back-pull rods 54 are respectively installed at the four corners of the flow channel plate 1, and the back-pull rods 54 are slidably connected to the back-pull rod sleeves 55.
[0031] It also includes long guide pillars 51, four groups of long guide pillars 51 are respectively installed on the four corners of the lower template 4, the flow channel plate 1, the upper template 2 and the lifting frame assembly 3 are respectively provided with long guide pillar holes, the Harvard 33 is installed with short guide pillar 1 52 and short guide pillar 2 53, and the upper template 2 is correspondingly provided with short guide pillar 1 hole and short guide pillar 2 hole.
[0032] When the product is formed, the runner plate 1 is lifted up with the press, and the anti-pull rod 54 follows the runner plate 1 to drive the anti-pull rod sleeve 55 to lift up, and the anti-pull rod sleeve 55 drives the upper template 2 to lift up, and the upper template 2 drives the side guide edge 21 to separate from the Haver 33. Since the wall thickness of the product in the Haver cavity part is thicker, the formed stabilizer bar bushing follows the upper template 2 and the lifting frame assembly 3 to lift and separate from the insert 41, and then the Haver 33 is pulled to both sides by the claws, and the Haver 33 slides to both sides, which facilitates the demolding of the formed stabilizer bar bushing. The long guide column 51, the first short guide column 52 and the second short guide column 53 are all used for guiding between the lifting frame assembly 3 and the upper template 2. The inner hole of the stabilizer bar bushing vulcanized by this device is not easy to flash, which is convenient for gluing and bonding the rod and the bushing, and the device is easier to demold.
