The specific embodiment
As depicted in figs. 1 and 2, a kind of fuel tank filler plastic mould of the present invention comprises upper mounted plate 2, bottom plate 18, blanking plate 3, master mold 4, slide block 6, male model 5, mould pin 7, base plate 9, core 15, ejecting mechanism and cooling system.The structure of upper mounted plate 2, bottom plate 18, blanking version, master mold 4, slide block 6, male model 5, mould pin 7, base plate 9 and core 15 and the connection between each parts, position relation is identical with prior art.When goods 14 are accomplished, pull down upper mounted plate 2, master mold 4 after, side direction is drawn back slide block 6, ejecting mechanism upwards ejects goods 14, can take off goods 14.On upper mounted plate 2, blanking plate 3 and master mold 4, be provided with running gate system; Running gate system comprise the sprue bushing 1 that is located on the upper mounted plate 2, be connected with sprue bushing 1 be located at the sprue 11 on the contact-making surface between blanking plate 3 and the master mold 4 and be located on the master mold 4 and be communicated with sprue 11 go into glue mouth 12; The die cavity of plastic mould is provided with 4; One mould goes out a plurality of goods 14, enhances productivity.In order to prevent the torsional deformation after the product depanning, sprue 11 is S-shaped on contact-making surface, promptly has the runner of two semicircular arcs to be formed by connecting.S shape sprue 11 can play prolongs glue and the effect that discharges exhaust, can eliminate the flow liner of plastic material, can prevent the torsional deformation after the product depanning, to produce goods attractive in appearance 14.
As shown in figures 1 and 3, to go into glue mouth 12 and be 3 one group and be connected to a runner jointly and be formed into glue mouth assembly, the glue mouth 12 of respectively going into of going into glue mouth assembly evenly distributes along the circumferencial direction of die cavity, and the runner of going into glue mouth assembly is communicated with sprue 11.Through the equally distributed glue mouth 12 of going into is set, can guarantee that into glue is even, to improve quality of item.The mould of present embodiment has 4 die cavities, and then go into glue mouth assembly and be provided with side by side 4 groups, a pair of in twos each end that is located at sprue 11 respectively, and the end of sprue 11 is positioned at two and goes into glue mouth assembly centre position, connection and reasonable arrangement, and it is smooth and easy to walk glue.
Like Fig. 1, Fig. 2 and shown in Figure 4, the core 15 of this mould is being positioned at open-ended and its inner hollow at base plate 9 places, and core 15 from bottom to top passes bottom plate 18, liftout plate 8, male model 5 and master mold 4, slide block 6 and male model 5 formation die cavities successively.Cooling system comprises the screw thread cooling tube 16 that is located at core 15 inside; The both ends open of this screw thread cooling tube 16 and inner hollow; The whole outer circumference surface of screw thread cooling tube 16 is provided with the screw thread that contacts the formation cooling water channel with core 15 inwalls; On screw thread cooling tube 16, be provided with water inlet pipe 17 that is communicated with cooling water channel and the outlet pipe 10 that is communicated with the hollow space of screw thread cooling tube 16, the tie point of water inlet pipe 17 and cooling water channel is positioned at the contacted position of screw thread of the end inwall and the screw thread cooling tube 16 of core 15 opening parts.Particularly, water inlet pipe 17 inserts base plates 9 with outlet pipe 10, and intake tunnel and exhalant canal on the base plate 9 be communicated with screw thread cooling tube 16 through being located at.In when cooling, the cooling water channel that cooling water gets into screw thread cooling tubes 16 outer walls from water inlet pipe 17 flows out through the outlet pipe 10 that is communicated with hollow space until the hollow space that flows to screw thread cooling tube 16, and mobile cooling of moving in circles.Because oil filler is a tube-like piece, need pay special attention to mold temperature, screw thread cooling tube 16 can take cooling water to must derive high heat mould depths; And cooling water is flowed fast, rapidly heat being taken away, thereby make mold temperature evenly moderate; Effectively the control mold temperature to improve the precision size of formed product, keeps the stability of physical property; Prevent the torsional deformation after the product depanning further, and can shorten the product shaping cycle, improved quality of item and production efficiency.
Like Fig. 1, shown in Figure 2, the ejecting mechanism of this mould comprises the department's tube 13 that is enclosed within on the core 15 and the liftout plate 8 that is connected with department tube 13, and liftout plate 8 is located at the top of bottom plate 18.Employing department tube ejecting mechanism ejects effectively, and reliability is high, and it is big and evenly, goods 14 are not yielding, can not stay tangible release vestige yet that department's tube 13 is released the strength of goods 14, also prevented to pull plastic product and the white phenomenon in top effectively.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
