Description
Technical field
The present invention relates to mould applications, and in particular to a kind of sealing strip mold.
Background technique
Automobile radiators are one of radiator key components and parts with sealing strip, and material is generally EPDM rubber, are mainly risen close
Envelope effect, prevents the leakage of radiator internal coolant.Production mode generally uses plate to be molded vulcanization, mold one
As use upper and lower mould planar structure.Due to the particularity of product structure, molded part is generally linear strip, because of Linear forming
Part torsional deformation is big, and during vulcanization produces filler, when filler easily deviates correct shaping position, and operation difficulty is big and imitates
Rate is low.In addition, easily causing filler deficiency, steam void, product consistency to be deteriorated as molded part deviates correct position, production is eventually led to
The key index buckling performance of product is poor, and hidden danger of quality is big.
Summary of the invention
Technical problems based on background technology, a kind of sealing strip mold proposed by the present invention.
A kind of sealing strip mold proposed by the present invention, including cope plate and lower template setting up and down, between cope plate is equipped with
Every multiple strip bulges of setting, lower template is equipped with multiple bar shaped groove bodies of spaced open top, strip bulge and item
Shape groove body corresponds, and bar shaped groove body and strip bulge cooperatively form type chamber, and bar shaped groove body two sides are respectively equipped with side along its length
To several positioning protrusion of distribution, strip bulge two sides are respectively equipped with distributed along its length several with positioning protrusion phase
The positioning groove body matched, positioning groove body and positioning protrusion correspond, and strip bulge both ends are respectively arranged with gib block, bar shaped groove body
Both ends are respectively equipped with along the perforative guiding groove body of lower die plate thickness direction, are oriented to groove body and gib block corresponds, gib block passes through
It wears corresponding guiding groove body and cooperates with guide groove body space.
Preferably, type chamber two sides are symmetrically arranged with torn edges slot.
Preferably, the shape of torn edges slot is ellipse.
Preferably, torn edges slot periphery is equipped with clout slot.
Compared with prior art, the invention has the following advantages:
(1) by the way that multiple one-to-one strip bulges and bar shaped groove body is arranged, multiple type chambers can be formed to primary right
Multiple molded parts carry out molding vulcanization, greatly improve the production efficiency of product.
(2) by the cooperation of positioning groove body and positioning protrusion can to cope plate and lower template strip bulge length direction
It is accurately positioned, it is ensured that do not misplace after cope plate and lower template molding, avoid molded part from deviateing correct shaping position, simultaneously
The side wall of positioning groove body plays the role of assisting sealing, further improves sealing pressure, and filler deficiency, steam void, product is avoided to cause
The problems such as density contrast, poor buckling performance, improve product quality produced.
(3) cope plate and lower template are carried out in the width direction of strip bulge by the setting of guiding groove body and gib block
It is accurately positioned, matches strip bulge one by one with bar shaped groove body, while gib block and the cooperation of guide groove body space can guarantee demoulding
Cope plate and lower template afterwards can be accurately positioned cooperation again, avoid molded part from deviateing correct shaping position, to improve production
The quality of product.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of sealing strip mold proposed by the present invention.
Fig. 2 is partial enlarged view at a kind of A of sealing strip mold proposed by the present invention.
Fig. 3 is a kind of structural schematic diagram of the lower template of sealing strip mold proposed by the present invention.
Fig. 4 is a kind of structural schematic diagram of the cope plate of sealing strip mold proposed by the present invention.
Specific embodiment
Referring to Fig.1-4, a kind of sealing strip mold proposed by the present invention, including cope plate 2 and lower template 1 setting up and down,
Cope plate 2 is equipped with spaced multiple strip bulges 4, and lower template 1 is equipped with multiple strip grooves of spaced open top
Body 3, strip bulge 4 and bar shaped groove body 3 correspond, and bar shaped groove body 3 and strip bulge 4 cooperatively form type chamber 9, bar shaped groove body 3
Two sides are respectively equipped with several positioning protrusion 5 distributed along its length, and 4 two sides of strip bulge are respectively equipped with along its length
The positioning groove body 6 that several and positioning protrusion 5 of distribution matches, positioning groove body 6 and positioning protrusion 5 correspond, strip bulge 4
Both ends are respectively arranged with gib block 7, and 3 both ends of bar shaped groove body are respectively equipped with along the perforative guiding groove body 8 of 1 thickness direction of lower template,
Groove body 8 and gib block 7 is oriented to correspond, gib block 7 through corresponding guiding groove body 8 and be oriented to 8 clearance fit of groove body.
The present invention once can carry out molding vulcanization to multiple molded parts, greatly improve the production efficiency of product；By fixed
It is accurately fixed that the cooperation of position groove body 6 and positioning protrusion 5 can carry out cope plate 2 and lower template 1 in the length direction of strip bulge 4
Position, it is ensured that do not misplace after cope plate 2 and the molding of lower template 1, avoid molded part from deviateing correct shaping position, while positioning groove body
6 side wall play the role of assist sealing, further improve sealing pressure, avoid filler deficiency, steam void, product low density,
The problems such as buckling performance is poor improves product quality produced；By the setting of guiding groove body 8 and gib block 7 to cope plate 2 and
Lower template 1 is accurately positioned in the width direction of strip bulge 4, matches strip bulge 4 one by one with bar shaped groove body 3, simultaneously
Gib block 7 and guiding 8 clearance fit of groove body can guarantee that cope plate 2 and lower template 1 after demoulding can be accurately positioned cooperation again, keep away
Exempt from molded part and deviate correct shaping position, to improve the quality of product.
