Abstract
The utility model discloses an injection mold for the injection molding of a double-U pipe fitting. The injection mold comprises an upper mold and a lower mold, which are matched with each other, a cavity for molding a base part of the double-U pipe fitting is formed inside the upper mold, and a locating hole for locating a single-U pipe body is formed inside the lower mold. According to the injection mold disclosed by the utility model, the locating hole is formed inside the lower mold, and the single-U pipe body is located inside the cavity, so that the double-U pipe fitting in an integral structure is manufactured by means of injection molding. The injection mold is good in sealing performance, long in service life and applicable to the production of the double-U pipe fitting.
Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of injection mould for the injection mo(u)lding of double-H groove weld pipe fitting.
Background technology
Before the utility model proposes, the double-H groove weld pipe fitting generally is made up of double-H groove weld pipe fitting part and double-H groove weld base portion, is tightly connected by hot melt between described double-H groove weld pipe fitting part and the double-H groove weld base portion.Because described double-H groove weld pipe fitting part is connected by sweat soldering with the double-H groove weld base portion, thus after using a period of time, the easy undergauge in sweat soldering face place or leak, lack service life.For improving the service life of described double-H groove weld pipe fitting, now improve the manufacturing process of described double-H groove weld pipe fitting, at first two single U bodys of moulding (described single U body is existing parts) are put into two single U bodys injection mould moulding together then, thereby are made the double-H groove weld pipe fitting.Because the double-H groove weld pipe fitting of described injection mo(u)lding together is monolithic construction, thus good airproof performance, long service life, local resistance loss is little.But because described injection mould is new die, so need the described injection mould of redesign.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of injection mould for the injection mo(u)lding of double-H groove weld pipe fitting to be provided.
In order to realize above purpose, a kind of injection mould for the injection mo(u)lding of double-H groove weld pipe fitting that the utility model provides, comprise the upper die and lower die that cooperatively interact, be provided with the die cavity for moulding double-H groove weld pipe fitting base portion in the described patrix, be provided with the locating hole for the single U body in location in the described counterdie.By in described counterdie, locating hole being set, and described single U body is positioned in the described die cavity, thereby injection mo(u)lding makes the double-H groove weld pipe fitting of monolithic construction, good airproof performance, long service life, local resistance loss is little.
In such scheme, the quantity of described locating hole is four, and the diameter of described locating hole matches with the caliber of described single U body.
The utility model is by arranging locating hole in described counterdie, and described single U body is positioned in the described die cavity, thereby injection mo(u)lding makes the double-H groove weld pipe fitting of monolithic construction, good airproof performance, long service life.
The utility model is compared with the prior art, and shows that fully its superiority is: simple in structure, and good airproof performance and long service life etc.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the double-H groove weld pipe fitting of monolithic construction;
Fig. 3 is the structural representation of the double-H groove weld pipe fitting of existing structure.
Among the figure: patrix 1, die cavity 1a, counterdie 2, locating hole 2a, double-H groove weld pipe fitting 3, single U body 3a, base portion 3b.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
As shown in Figure 1: present embodiment provides a kind of injection mould for the injection mo(u)lding of double-H groove weld pipe fitting, comprise the patrix 1 and the counterdie 2 that cooperatively interact, be provided with the die cavity 1a for moulding double-H groove weld pipe fitting 3 base portion 3b in the described patrix 1, be provided with the locating hole 2a for the single U body 3a in location in the described counterdie 2.By in described counterdie 2, locating hole 2a being set, and described single U body 3a is positioned in the described die cavity 1a, thereby injection mo(u)lding makes the double-H groove weld pipe fitting 3 of monolithic construction, good airproof performance, long service life.The quantity of described locating hole 2a is four, and the diameter of described locating hole 2a matches with the caliber of described single U body 3a.
The utility model is by arranging locating hole 2a in described counterdie 2, and described single U body 3a is positioned in the described die cavity 1a, thereby injection mo(u)lding makes the double-H groove weld pipe fitting 3 of monolithic construction, good airproof performance, long service life.
Claims (2)
1. an injection mould that is used for the injection mo(u)lding of double-H groove weld pipe fitting comprises the upper die and lower die that cooperatively interact, and it is characterized in that: be provided with the die cavity for moulding double-H groove weld pipe fitting base portion in the described patrix, be provided with the locating hole for the single U body in location in the described counterdie.
2. the injection mould for the injection mo(u)lding of double-H groove weld pipe fitting as claimed in claim 1, it is characterized in that: the quantity of described locating hole is four, the diameter of described locating hole matches with the caliber of described single U body.
