The specific embodiment
As Fig. 3～shown in Figure 8, mould structure provided by the invention comprises the 1st module the 50, the 2nd module 60 and core rod 70.Core rod 70 is installed on the 1st module 50, is used for the moulding of injection article.Be formed with groove 54 on the face relative with the 2nd module 60 on the 1st module 50, and inside is formed with cooling tube 52, groove 54 is used to install the core rod 70 that the injection article moulding is used.The inside of core rod 70 is formed with cooling tube 72, and in order to make the injection article of hollow shape, the cross section of core rod 70 is circular.In addition, the edge of core rod 70 is formed with the inclined plane 70a that tilts with specific angle, and resin contacts with inclined plane 70a and solidifies the injection article that then just can form hollow structure.The plane 71b of core rod 70 can be inserted in the groove 54 of the 1st module 50, and the contact be fixed on the 1st module 50, the inclined plane 71a of core rod 70 then contacts with the 2nd module 60.The inside of the 2nd module 60 is formed with cooling tube 62, is formed with groove 64 on it Yu on 50 contacted 60a of the 1st module.Groove 64 is the groove that forms to the inboard of the 2nd module 60, and cooling tube 62 is formed on the edge of groove 64.In order to combine with the inclined plane 71a of core rod 70, groove 64 is to form with the corresponding shape of the inclined plane 71a of core rod 70, and the edge of groove 64 is formed with stage 64a, and the inclined plane 70a of stage 64a and core rod 70 together is formed for injecting the injection moulding space 65 of resin.Injection moulding space 65 is for being used for the space of injection molded injection article 100, and liquid resin can be crimped on a time-out by not shown inlet inflow injection moulding space 65, the 1 modules 50 and the 2nd module 60 can prevent that resin from flowing out to outside the mould.Simultaneously,, be formed with the cooling tube 52,62,72 that is used to cool off resin respectively on the 1st module the 50, the 2nd module 60 and the core rod 70 in order to cool off resin, cooling tube 52,62, stream is useful on the water that absorbs the resin heat in 72.In the injection article 100 that utilizes die forming provided by the invention, hollow bulb 101 thickness that form hollow structure are thicker than the thickness of lateral surface 102.Cooling tube 72 in the core rod 70 is formed on the position near its inclined plane 70a, therefore can the resin that form hollow bulb 101 be cooled off with the speed identical with other position.Promptly, when utilizing the Mold Making diverse location of prior art to have the injection article 100 of different-thickness, because of cooling off with different speed at different positions, so this mould might produce distortion or distortion, but, the cooling tube 72 of core rod 70 inside is formed on the position that can make the cooling velocity close inclined plane 70a identical with the cooling velocity of other thin part in the mould structure provided by the invention, thereby can make the cooling velocity in injection moulding space 65 identical.Because the cooling tube 72 of core rod 70 is formed near inclined plane 70a part,, the thicker hollow bulb of thickness 101 is cooled off with identical cooling velocity with other position even the cooling water that flows in the cooling tube 52,62,72 has identical temperature.On the other hand, if injection article 100 and cooling tube 72 spacings that are formed in the core rod 70 are not adjusted, just can adjust as long as provide than the low cooling water of the cooling water temperature in other cooling tube 52,62 cooling velocity of the injection article 100 of different-thickness to the cooling tube 72 of core rod 70.As Fig. 9, shown in Figure 10, according to the device shape and the structure of making injection article 100, the 1st module 50 in the mould structure provided by the invention can move back and forth by drive units such as oil gears, so that injection article 100 moulding, also can the 2nd module be moved back and forth, so that injection article 100 moulding by drive unit.Be that mould structure provided by the invention has the advantage that can move any one module in the 1st, the 2 module, below, describe utilizing mould provided by the invention to carry out injection moulding process with reference to Fig. 3 to Figure 10.At first, adopt not shown bolting to be combined on the 1st module 50 core rod 70, that is,, use bolting then the groove 54 that the plane 71b of core rod 70 puts into the 1st module 50.The 1st module 50 is fixed on the not shown support frame, and the 2nd module 60 then moves by drive unit, can form the injection moulding space 65 of injection molded like this.Be formed with the not shown inlet that is used for injecting resin on the 1st module 50 that is fixed, can inject liquid resin by certain pressure by inlet to injection moulding space 65.In addition, the resin that is injected in the injection moulding space 65 can be cooled off by the cooling waters that are flowing in the cooling tube in the 1st module the 50, the 2nd module 60 and the core rod 70 52,62,72, and can cool off the thicker hollow bulb of thickness 101 with the speed identical by the cooling tube 72 that is formed on the core rod 70 with other position, in the time of can preventing to utilize mould molding injection article 100 provided by the invention thus because of different distortion and the distortion that produce of thickness.In addition, can injection article 100 be cooled off by the cooling water that flows in the cooling tube 52,62,72, the injection article that is cooled can be separated from core rod 70 when the 2nd module 60 is retracted original position, repeats said process and just can produce in batches.
