Description

In a kind of mould, be difficult for rushing curved core structure

Technical field

The utility model relates to the parts of mould, in particular: it relates to a kind of mould and is difficult for rushing curved core structure.

Background technology

Mould is as the term suggests be a system mould, be widely used in a system field, for making the production in enormous quantities of pen, provide guarantee, in mould, core is as one of part the most key in mould, the moulding of product is had to very important effect, core is arranged on dynamic model one side, common core is wholely set mostly, but the product that the core being wholely set can only the comparatively simple same tapering of corresponding moulding, cannot moulding the complex product of different taperings, therefore core can be divided into upper core and lower core two parts.

At present, a model core on market, between upper and lower two cores, it is simple plane contact, such core structure is when producing product, between upper and lower core, can be injection molding the material pouring in machine rushes curved, be between upper and lower two cores, to produce dislocation movement cannot align, can have a certain impact to the moulding of product, so need to be improved.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide and in a kind of mould, is difficult for rushing curved core structure.

For achieving the above object, the utility model provides following technical scheme: in a kind of mould, be difficult for rushing curved core structure, comprise core body, described core body is comprised of upper core and lower core two parts, the upper end of described lower core is provided with protuberance, the upper end of described upper core is provided with the depressed part suitable with described protuberance, described protuberance is conflicted and is coordinated with described depressed part, described protuberance comprises cylinder table and is located at first frustum of a cone on cylinder table, between described cylinder table and the described frustum of a cone, be wholely set, described first frustum of a cone comprises the first conflict conical surface and the first level table, described depressed part indent has the second conflict conical surface and the second level table, the diameter of described the first level table is greater than the diameter of described the second level table, the height of the described first conflict conical surface is less than the height of the described second conflict conical surface, the described first conflict conical surface and the described second conflict conical surface are conflicted and are coordinated, the other end of the relatively described depressed part of described upper core is provided with the first fixed part, the other end of the relatively described protuberance of described lower core is provided with the second fixed part.

By adopting technique scheme, change the structure of traditional dichotomic type core, changed the way of contact of upper core and lower core, by simple face and the conflict between face, by suction, guarantee the globality of core and lower core, made into be coordinated by the conflict of protuberance and depressed part, in assurance, core and lower core are in axiality, can effectively avoid core body to be injection molding the material that machine pours rushes curved, reliability is high, improved the service life of a mould, the setting of cylinder table is the outstanding position of the moulding of product, product has different taperings, therefore the effective somatotype of the core of integral type, therefore adopt the core of dichotomic type, on protuberance, the diameter of the first level table is greater than the diameter of the second level table of depressed part and the height setting that the height of the first conflict conical surface is less than the second conflict conical surface, make the end that is engaged in of protuberance and depressed part reserve certain spatial joint clearance, convenient processing in stabilized seal between core and lower core on guaranteeing, cost-saving, upper core and lower core are fixed on Die and mould plate by the first fixed part and the second fixed part respectively, guarantee the stable of core, avoid spinning of core.

In figure: 1, core body; 11, upper core; 12, lower core; 2, protuberance; 21, cylinder table; 22, the frustum of a cone; 221, the first conflict conical surface; 222, the first level table; 3, depressed part; 31, the second conflict conical surface; 32, the second level table; 4, the first fixed part; 5, the second fixed part.

The specific embodiment

Shown in Fig. 4, in a kind of the mould of the present embodiment, be difficult for rushing curved core structure, comprise core body 1, described core body 1 is comprised of upper core 11 and lower core 12 two parts, the upper end of described lower core 12 is provided with protuberance 2, the upper end of described upper core 11 is provided with the depressed part 3 suitable with described protuberance 3, and described protuberance 2 is conflicted and coordinated with described depressed part 3.

Change the structure of traditional dichotomic type core, changed the way of contact of upper core 11 and lower core 12, by simple face and the conflict between face, by suction, guarantee the globality of core 11 and lower core 12, made into be coordinated by the conflict of protuberance 2 and depressed part 3, in assurance, core 11 and lower core 12 are in axiality, can effectively avoid core body 1 to be injection molding material that machine pours and rush curvedly, reliability is high, has improved the service life of a mould.

Described protuberance 2 comprises cylinder table 21 and is located at the frustum of a cone 22 on cylinder table, one-body molded between described cylinder table 21 and the described frustum of a cone 22, the described frustum of a cone 22 comprises the first conflict conical surface 221 and the first level table 222, described depressed part 3 indents have the second conflict conical surface 31 and the second level table 32, the diameter of described the first level table 222 is greater than the diameter of described the second level table 32, the height of the described first conflict conical surface 221 is less than the height of the described second conflict conical surface 31, and the described first conflict conical surface 221 and the described second conflict conical surface 31 are conflicted and coordinated.

The setting of cylinder table is the outstanding position of the moulding of product, product has different taperings, therefore the effective somatotype of the core of integral type, therefore adopt the core of dichotomic type, on protuberance 2, the diameter of the first level table 222 is greater than the diameter of the second level table 32 of depressed part 3 and the height setting that the height of the first conflict conical surface 221 is less than the second conflict conical surface 31, make protuberance 2 and the end that is engaged in of depressed part 3 reserve certain spatial joint clearance, on guaranteeing, convenient processing in stabilized seal between core 11 and lower core 12, cost-saving.

The other end of the relatively described depressed part 3 of described upper core 11 is provided with the first fixed part 4, the other end of the relatively described protuberance 2 of described lower core 12 is provided with the second fixed part 5, upper core 11 and lower core 12 are fixed on Die and mould plate by the first fixed part 4 and the second fixed part 5 respectively, guarantee the stable of core, avoid spinning of core.

Described upper core 11, lower core 12 all adopt S136 mould steel to make, and S136 mould steel has good corrosion resistance, polishability, and good wearability, machining property adopt S136 mould steel core can significantly promote service life.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
