Abstract
The utility model relates to a device facilitating quick maintenance of a plastic mould. The device comprises a product (1), a fixed mould core (2), a movable mould core (3), perhardened steel movable mould mold inserts (4) and movable mould cushion blocks (5), wherein the foot part of the fixed mould core (2) is arranged on the perhardened steel movable mould mold inserts (4); the movable mould core (3) is mounted in a cavity formed by the fixed mould core (2) and the perhardened steel movable mould mold inserts (4); and the movable mould cushion blocks (5) are mounted at the bottom surfaces of the perhardened steel movable mould mold inserts (4). The device can ensure the product quality and improve the production efficiency.
Description
Technical field
The utility model belongs to technical field of mold, particularly relates to a device that makes things convenient for the mould of plastics rapid-maintenance.
Background technology
As shown in Figure 2, because polypropylene easily produces overlap in injection moulding process, the overlap part will remain on the die joint of mould, and the collapse die joint of mould of so easy pressure affects the quality of mold use life-span and product; And after die joint in case press collapses, cover half core and the moving-mould-core integral body face that fall can only be processed, so cause the time lengthening (needing at least more than two days) that repairs a die, will further affect the output of product.
The utility model content
Technical problem to be solved in the utility model provides a device that makes things convenient for the mould of plastics rapid-maintenance, can guarantee product quality, enhances productivity.
The technical scheme that its technical problem that solves the utility model adopts is: a device that makes things convenient for the mould of plastics rapid-maintenance is provided, comprise product, the cover half core, moving-mould-core, perhardened steel dynamic model mold insert, the dynamic model cushion block, described cover half core foot places on the perhardened steel dynamic model mold insert, in the cavity that cover half core and perhardened steel dynamic model mold insert form moving-mould-core is installed, perhardened steel dynamic model mold insert bottom surface is equipped with the dynamic model cushion block.
Described perhardened steel dynamic model mold insert underrun screw is equipped with the dynamic model cushion block.
In an actor's rendering of an operatic tune that described cover half core and moving-mould-core form product is installed.
The material of described cover half core adopts SKD61.
Described cover half core quenching hardness is HRC50; Perhardened steel dynamic model mold insert hardness is HRC38.
The quenching hardness of described cover half core is HRC51; Perhardened steel dynamic model mold insert hardness is HRC39.
The quenching hardness of described cover half core is HRC52; Perhardened steel dynamic model mold insert hardness is HRC40.
Beneficial effect
The utility model can guarantee product quality, enhances productivity.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a device that makes things convenient for the mould of plastics rapid-maintenance, comprise product 1, cover half core 2, moving-mould-core 3, perhardened steel dynamic model mold insert 4, dynamic model cushion block 5, described cover half core 2 foots place on the perhardened steel dynamic model mold insert 4, in the cavity that cover half core 2 and perhardened steel dynamic model mold insert 4 form moving-mould-core 3 are installed, and perhardened steel dynamic model mold insert 4 bottom surfaces are equipped with dynamic model cushion block 5.
Described perhardened steel dynamic model mold insert 4 underrun screws are equipped with dynamic model cushion block 5.
In an actor's rendering of an operatic tune that described cover half core 2 and moving-mould-core 3 form product 1 is installed.
At first, the material of cover half core 2 adopts SKD61, quenching HRC50-52, perhardened steel dynamic model mold insert 4 hardness are HRC38-40, if and keep a certain proportion of relation that increases progressively through the relative hardness of evidence perhardened steel dynamic model mold insert 4 and cover half core 2, when mould presses the phenomenon of collapsing to occur, damaged by pressure only can be the pressure of perhardened steel dynamic model mold insert 4 and perhardened steel dynamic model mold insert 4 collapse part relatively evenly, therefore when perhardened steel dynamic model mold insert 4 damages by pressure, only need to press the position that collapse to polish with grinding machine perhardened steel dynamic model mold insert 4, change again corresponding dynamic model cushion block 5(or with dynamic model cushion block 5 bed hedgehoppings) can finish and repair a die.What this mechanism had saved greatly repairs a die the time (only needing approximately 2 hours), and has reduced the impact that causes to the production shipment because repairing a die.
