Abstract
The utility model provides a die structure of a grab of an injection mold. The die structure comprises a fixed die and a movable die, wherein the movable die is provided with an oblique top block, a chute is formed in one face of the movable die, facing the fixed die, and the oblique top block is installed in the chute and can slide relative to the movable die. A groove which forms the grab part of a cavity is formed on the surface where the extending end and the movable die are combined. One end of the inclined top block extends toward the fixed die, and during die assembly, the combined face of the extending end and the movable die is a lateral mould joint. The lateral mould joint is arranged at the edge of an injection mould main body of the cavity. The inclined top block can be detached and changed. When the inclined top block is severely worn to cause overlarge flash, the flash can be eliminated by changing a new inclined top block. According to the die structure provided by the utility model, the injection mold is not easy to generate flash. After the die is abraded, even if flashes are generated, the die can be trimmed under the premise of not affecting the quality of the grab. Therefore, the percent of pass of the products is improved.
Description
Technical field
The utility model belongs to moulding injection moulding field, relates to a kind of mould structure, particularly a kind of mould structure of moulding grab.
Background technology
In the application of automobile in modern age, general automobile moulding adopts grab and square hole to coordinate to carry out the assembling between product conventionally, and grab is located on moulding body, so reduces the cost, simple again.
In prior art, as shown in Figure 2, moulding grab 2 is directly touched and is worn moulding by dynamic model 3 and cover half 5, and dynamic model 3 forms traditional die joint 7 with cover half 5 on moulding grab 2.Therefore,, as long as mould weares and teares, be just easy to produce overlap at moulding grab 2 places, and very easily cause moulding grab 2 to scrap in later stage deburring process.Therefore need a kind of mould structure that more can guarantee product quality.
Utility model content
The utility model provides a kind of mould structure of moulding grab, and object is to make moulding be difficult for producing overlap, and is convenient to the overlap that post-processed produces, and improves product percent of pass.
To achieve these goals, the technical scheme that the utility model is taked is:
The mould structure of described moulding grab, comprise fixed half and moving half, it is characterized in that: also comprise the slanted kicking block being arranged on dynamic model, described slanted kicking block, described cover half and the described dynamic model die cavity forming that combines comprises grab part and moulding body part, and described slanted kicking block and described dynamic model are undercut face at the faying face at described moulding body part edge.
Described slanted kicking block and described dynamic model are slidably matched, and the part that described slanted kicking block inserts described dynamic model is connected with the ejecting mechanism that drives described slanted kicking block.
Described slanted kicking block is provided with the groove suitable with described moulding grab shape.
The glide direction of described slanted kicking block and described undercut face are oblique angle.
Described slanted kicking block is removably mounted on described dynamic model.
Adopt technique scheme, make moulding be difficult for producing overlap.After die wear, even if produce overlap, also can under the prerequisite that does not affect grab quality, carry out deburring.Improved the qualification rate of product.And simple in structure, when finning is serious can by change slanted kicking block easy improve the quality of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the mould structure of a kind of moulding grab of the utility model;
Fig. 2 is the structural representation of the mould structure of moulding grab in background technology.
Being labeled as in figure:
1, moulding body part; 2, grab part; 3, dynamic model; 4, slanted kicking block; 5, cover half; 6, undercut face; 7, traditional die joint.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
As shown in Figure 1, the utility model provides a kind of mould structure of moulding grab.Comprise dynamic model 3, cover half 5.On dynamic model 3, be provided with a slanted kicking block 4.Dynamic model 3 is provided with a chute towards cover half 5 one sides, and slanted kicking block 4 is arranged in chute and dynamic model 3 slips relatively.The surface that external part combines with dynamic model 3 is provided with the groove that forms grab part 2.
Stretch out towards cover half 5 slanted kicking block 4 one end, and during matched moulds, slanted kicking block 4 is combined formation die cavity with cover half 5, dynamic model 3, and die cavity comprises grab part 2 and moulding body part 1.Slanted kicking block and dynamic model 3 are undercut face 6 at the faying face of moulding body part 1 edge.Because this undercut face 6 is arranged on the edge of moulding body part 1, even if occur that overlap is also the edge that appears at moulding body.During later stage deburring, can not impact moulding grab, improve product percent of pass.
The direction of chute is oblique angle with respect to undercut face 6, and matched moulds rear side is to closely pressing of die joint 6.Slanted kicking block 4 can dismounting and change, and when slanted kicking block 4 serious wear cause overlap excessive, the slanted kicking block 4 that only need more renew can be eliminated overlap, is therefore difficult for producing overlap.Slanted kicking block 4 inserts dynamic model 3 one end and is connected with liftout attachment, and during the demoulding, liftout attachment can eject slanted kicking block 4 from dynamic model 3, makes mould separated smoothly.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
