Abstract
The utility model relates to a water-jacket ejector-pin cooling waterway for an injection mold. The water-jacket ejector-pin cooling waterway for the injection mold comprises a mold cavity and a mold core, wherein a molded plastic part is arranged between the mold cavity and the mold core. The mold core is installed on a mold foot, and a lower subplate is installed under the mold foot. An ejector-pin subplate and an ejector-pin plate are arranged on the lower subplate, and an ejector pin is connected onto the ejector-pin plate and penetrates through the mold core to contact with the plastic part. A cooling waterway is distributed into the mold core, and a circular insert block is installed in the mold core. The ejector pin penetrates through the circular insert block, a groove is arranged in the outer surface of the circular insert block and is communicated with the cooling waterway, and a water-jacket piece is installed in the cooling waterway.
Description
Technical field
The utility model relates to a kind of injection mold water isolation type thimble cooling water channel, belongs to injection mold field.
Background technology
Adopt injection mold to produce plastic product (plastic), after plastic injection mo(u)lding, need to carry out plastic cooling fast, therefore, in injection mold, be all provided with cooling water channel (water route), the reasonability that cooling water channel distributes and with the harmony of mould inside structure, directly affect production efficiency and the plastic part quality of mould, the distribution of conventional art cooling water channel is designed by veteran mould master worker rule of thumb conventionally, for the higher plastic of cooling effect, particularly require high plastic to thimble position is cooling, often cannot reach designing requirement, cause plastic part quality poor, even scrap, production efficiency is low, cost is high.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, and a kind of water proof sheet methods for cooling that adopts is provided, and water channel is arranged evenly, can be non-interference with mould inside structure, make again plastic good cooling results, quality assurance, the injection mold water isolation type thimble cooling water channel that cost is low.
The technical scheme of the utility model injection mold water isolation type thimble cooling water channel is: comprise mold cavity and core, between die cavity and core, there is moulding plastic, core is arranged on mould pin, mould underfooting is equipped with lower subplate, on lower subplate, thimble subplate and ejector retainner plate are set, connecting ejector pin on ejector retainner plate, thimble contacts with plastic through core, cooling water channel distributes in described core, it is characterized in that in described core, circle being installed inserts, thimble is inserted through circle, the outer surface that circle is inserted arranges groove, groove is communicated with cooling water channel, in described cooling water channel, be equipped with water proof sheet.
Injection mold water isolation type thimble cooling water channel of the present utility model, circle is installed in described core to be inserted, thimble is inserted through circle, the outer surface that circle is inserted arranges groove, groove is communicated with cooling water channel, in described cooling water channel, be equipped with water proof sheet, cooling water channel, in the time flowing through thimble place, flows through around the groove of the round outer surface of inserting, and cooling water channel and thimble are non-interference, so neither need mobile thimble, affect ejecting of plastic, can make again cooling water channel be evenly distributed, plastic good cooling results, guarantee plastic part quality, enhance productivity.
Injection mold water isolation type thimble cooling water channel of the present utility model, insert top and bottom of described circle has seal groove, and sealing ring is installed in seal groove, and sealing ring contacts with core, improves sealing property, prevents that cooling water channel from leaking.
Accompanying drawing explanation
Fig. 1 is the utility model injection mold water isolation type thimble cooling water channel structure schematic diagram;
Fig. 2 is the local enlarged diagram in A place of Fig. 1.
The specific embodiment
The utility model relates to a kind of injection mold water isolation type thimble cooling water channel, as Fig. 1, shown in Fig. 2, comprise mold cavity 1 and core 2, between die cavity 1 and core 2, there is moulding plastic 11, core is arranged on mould pin 3, mould underfooting is equipped with lower subplate 6, thimble subplate 5 and ejector retainner plate 4 are set on lower subplate 6, connecting ejector pin 8 on ejector retainner plate, thimble 8 contacts with plastic 11 through core 2, cooling water channel 15 distributes in described core 2, it is characterized in that in described core 2, circle being installed inserts 7, thimble 8 inserts 7 through circle, insert 7 outer surface of circle arranges groove 12, groove 12 is communicated with cooling water channel 15, in described cooling water channel 15, be equipped with water proof sheet 9.Circle is installed in described core 2 and is inserted 7, thimble 8 inserts 7 through circle, insert 7 outer surface of circle arranges groove 12, groove 12 is communicated with cooling water channel, in described cooling water channel 15, be equipped with water proof sheet 9, cooling water channel is in the time flowing through thimble 8 place, groove 12 around round 7 outer surfaces of inserting flows through, cooling water channel 15 is non-interference with thimble 8, so neither needs mobile thimble, affects ejecting of plastic, can make again cooling water channel be evenly distributed, plastic good cooling results, guarantees plastic part quality, enhances productivity.Insert 7 tops and bottom of described circle has seal groove 13, and sealing ring 14 is installed in seal groove 13, and sealing ring 14 contacts with core 2, improves sealing property, prevents that cooling water channel from leaking.
