Description
Technical field
The utility model is related to technical field of automobile accessories, and in particular to a kind of sealing strip hot bending die box.
Background technology
Automobile door and window corner part need to use doorframe rubber weather strip to seal.Due to part exist processing, rigging error and
There are system tolerances for vehicle, often will appear doorframe rubber weather strip and doorframe corner on business poor mismatch and occur with ceiling not
It is bonded phenomenon.Therefore, need the assembling shape with die treatment sealing strip, the corner of previous product usual in sealing strip production mouth
Using vulcanization of rubber injection mould, it is suitable for the more complicated shape of product, for example the upholstery border of product corner compares matrix
Decorate the length of side, need to plate muscle play a part of cover, this kind of mold it is complicated, design cost height, the processing cost period is long,
The mold later stage heavy workload of maintenance connects moreover, the position being molded afterwards can leave ugly lapping defect and occurs aberration at angle, appearance
Quality defect.
Utility model content
The utility model is in view of the deficienciess of the prior art, provide a kind of sealing strip hot bending die of automobile door and window
Box.
To achieve the goals above, the utility model provides the following technical solutions：A kind of sealing strip hot bending die box, including
Cope plate and lower template, it is characterised in that：The lower surface of the cope plate is equipped with a lateral arc-shaped convex, the lower template
Upper surface is equipped with a lateral circular groove, which is formed by closed space with groove and is matched with sealing strip, described
Cope plate and lower template are respectively equipped with hinged casing one and casing two, and cope plate side and lower template side are respectively equipped with
Heater wire one for heating cope plate and the heater wire two for heating lower template.
Further, the casing one of the cope plate and casing two of lower template is located at cope plate and lower template deviates from
The side of sealing strip bending direction.
Further, the protrusion and groove number of combinations are one or more.
Still further, the transverse direction arc-shaped convex is identical with the lateral radian of circular groove.
Compared with existing hot injection molding technology, the utility model has the following advantages：
1, cope plate, lower template, heater wire one and heater wire two constitute the primary structure of the utility model, cope plate with
The closed space that lower template is formed is matched with strip is sealed, and prevents sealing strip when hot bending towards deforming outside closed space,
It ensure that the shape integraty of sealing strip.
2, protrusion and the number of combinations of groove are one or more, arc-shaped convex when protrusion is combined as multiple with groove
It rises and groove can be mutually juxtaposed on cope plate and lower template, this has not only saved the cost of mold, but also greatly improves
The efficiency of sealing strip hot bending.
3, the connection type of cope plate and lower template is hinge connection, takes cope plate away after reducing hot bending and brings back upper mold
The process of plate can directly overturn cope plate and carry out tearing conjunction open, save the time, improved production efficiency.

Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
The lower surface of a kind of sealing strip hot bending die box, including cope plate 1 and lower template 2, cope plate 1 is equipped with a lateral circle
The upper surface of arc convex 3, lower template is equipped with a lateral circular groove 4, which is formed by closed space with groove 4
It is matched with 5 shape of sealing strip, wherein the protrusion side 51 of sealing strip 5 is positioned in the groove 4 of lower template 2, and sealing strip 5 is put down
Smooth side 52 is limited by the protrusion 3 of cope plate 1, generally lower template 2 is placed on the table in actual mechanical process, lower template
It is put on 2 after sealing strip 5 and covers cope plate 1 again, even if the protrusion 3 of cope plate 1 and the groove 4 of lower template 2 misplace, sealing
The protrusion side 51 of item 5 will not deform, and largely ensure that the product stability in actual mechanical process.In addition, convex
Rise 3 and the quantity that combines of groove 4 can be it is multiple, multiple raised 3 and the combination of groove 4 arranged side by side on cope plate 1 and lower template 2
Row, not only save die cost, can also the disposable multigroup sealing strip 5 of hot bending, improve the efficiency of 5 hot bending of sealing strip.
Cope plate 1 and lower template 2 are respectively equipped with hinged casing 1 and casing 2 12, casing 1 and casing two
12 mutual dislocations, the rotation axis 13 among casing 1 and casing 2 12 rotate, and can not have to unload cope plate 1 or lower template 2
The sealing strip 5 after hot bending is can be taken off, reduces the process for unloading lower cover in common hot bending, improves production efficiency.
1 side of cope plate and 2 side of lower template are respectively provided with the heater wire 1 of heating cope plate 1 and for heating
The heater wire 2 62 of lower template 2, heating speed is faster.
A kind of sealing strip hot bending die box disclosed by the utility model works in this way：Mold box is placed on desktop
On, it connects the power cord of the lower heater wire 2 62 of 2 side of upper heater wire 1 and lower template of 1 side of cope plate and is powered pre-
Heat, when temperature reaches 75 DEG C -85 DEG C, by the protrusion side 51 of the sealing strip 5 after cutting be caught in lower template 2 make sealing strip 5 at
It is arc-shaped, it is then rotated further by cope plate 1 and cope plate 1 is made to cover in lower template 2, cope plate 1 and lower template 2 is made to be bonded and press
Tightly, it after hot bending 5-6 minutes, rotates cope plate 2 and opens mold box, take out the sealing strip 5 after hot bending, be quickly put into sealing strip
It is cooled down in cold water, upper sealing strip 5 is dragged for after the completion of cooling and is dried, that is, completes hot bending process.
Embodiment described in the utility model is only example to clearly illustrate, and not to embodiment
Restriction.For those of ordinary skill in the art, other not similar shapes can also be made on the basis of the above description
The variation or variation of formula.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this aobvious and easy
