Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Fig. 8
A kind of injection molding of automobile tire flap, comprise front cavity 1, rear cavity 2 and middle template 3, described front cavity bottom is provided with the first core be made up of inversed taper platform 1a and the cylinder 1b that is connected to rounding frustum lower end, described rear cavity top is provided with the second core be made up of frustum of a cone 2a and the cylinder 2b that is connected to frustum upper end, the groove 3a that inwall is curved is provided with in the middle part of described middle template, when first core and the second core insert in groove, front cavity lower surface and rear cavity upper surface fit, thus formation die joint, make groove match to form the die cavity 4 for cast tire rim strip with the first core and the second core simultaneously, be provided with locating ring 5 in the middle part of described front cavity and be installed on the sprue bush 8 be connected in the middle part of locating ring and with the runner 7 be opened on die joint 6, to inject plastic cement in mould, the described runner other end is connected with die cavity, thus plastic cement is injected in die cavity to form tire flap, be equipped with in the middle part of described rear cavity and draw material nail 9, to be pulled out from front cavity by waste material when parting, described front cavity, rear cavity and middle template are also evenly equipped with longitudinal hole 10, described longitudinal hole are provided with heating rod 11, thus be mold heated.So that this mold injects cross section is curved, middle part is thicker, the rim strip B that two edges are gradually thin from inside to outside, and rim strip center line is provided with the circular hole B1 passed for inner tube valve.
In the present embodiment, described die joint is evenly equipped with at least four runners 7, so that plastic uniform injects in die cavity, described runner comprises the first curved channel 71 be arranged on front cavity lower surface and the second curved channel 72 being arranged at rear cavity upper surface, described runner afterbody is provided with arc and turns portion 73, to slow down the flowing velocity of plastic cement, described arc turns portion's end and is provided with cold slug well 74, so that cooling after plastic cement cast, arc turns radical side and is provided with the runner 75 be connected with die cavity, by runner to injecting glue in die cavity.
In the present embodiment, reset for the ease of middle template, with the stroke of template in limit, one side of described front cavity is also provided with middle template position-limit mechanism, described middle template position-limit mechanism comprises the vertical spacing plate 121 being connected to front cavity one side, described limiting plate offers stopper slot 122, wear the banking pin 123 being equipped with and being connected with middle template in described stopper slot, thus centering template is carried out spacing.
