Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It is to be appreciated that if relating to directionality instruction (such as up, down, left, right, before and after ...) in the embodiment of the present invention,
Then directionality instruction be only used for explain under a certain particular pose (as shown in the picture) between each component relative positional relationship,
Motion conditions etc., if the particular pose changes, directionality instruction is also correspondingly changed correspondingly.
In addition, being somebody's turn to do " first ", " second " etc. if relating to the description of " first ", " second " etc. in the embodiment of the present invention
Description be used for description purposes only, be not understood to indicate or imply its relative importance or implicitly indicate indicated skill
The quantity of art feature." first " is defined as a result, the feature of " second " can explicitly or implicitly include at least one spy
Sign.It in addition, the technical solution between each embodiment can be combined with each other, but must be with those of ordinary skill in the art's energy
It is enough realize based on, will be understood that the knot of this technical solution when conflicting or cannot achieve when occurs in the combination of technical solution
Conjunction is not present, also not the present invention claims protection scope within.
As shown in Figures 1 to 3, the embodiment of the invention provides a kind of mold core flexible connection groups for polyurethane blowing mold
Part, including attachment base 1, limit angle connecting rod 2 and connecting shaft 3, the attachment base 1 and connecting shaft 2 are respectively provided with two, the attachment base
Slot 11 is provided on 1, the limit angle connecting rod 2 is arranged in the slot 11 of two attachment bases 1, on the 11 two sides inner wall of slot
It is provided with perforative first hole 12, is provided on the limit angle connecting rod 2 through the second hole 21 of the limit angle connecting rod 2, institute
It states connecting shaft 3 and the attachment base 1, limit angle connecting rod 2 is rotatably connected across first hole 12, the second hole 21；Institute
It states and is provided with the planar section 22 connected with 11 bottom of slot and the planar section 22 and the limit on limit angle connecting rod 2
The side plate bending 23 of the side connection of angle connecting rod 2, two attachment bases 1 pass through the limit angle connecting rod 2 being arranged in slot 11 and connect, even
Spindle 3 plays positioning action, and two attachment bases 1 can be rotated under the action of limiting angle connecting rod 2, turn to certain position when
Wait, limit 2 both ends of angle connecting rod planar section 22 and 11 bottom of slot plane contact, two attachment bases 1 are limited, prevent after
Continuous rotation, specifically, the attachment base 1 is in concave.
Preferably, the planar section 22 is vertical with the limit side of angle connecting rod 2.When being rotated so that two attachment bases
1 when being on same level straight line, i.e. when two 1 maximum distance of attachment base, planar section 22 and the plane of 11 bottom of slot are connect
Touching, limits attachment base 1.
Specifically, the side plate bending 23 and second hole 21 are concentric, setting is so that two attachment bases 1 are limiting angle in this way
When rotating under the connection of connecting rod 2, side plate bending 23 reduces friction along the plane contact of rotation direction and the bottom of slot 11.
Further, third hole 13 is provided on the attachment base 1,13 internal screw thread of third hole is connected with adjusting screw
14, position of the adjustable attachment base 1 of screw 14 when connecting with model is adjusted, makes it possible to adapt to various sizes of product.
Working condition of the invention is: one of attachment base 1 is passed through to the fixed peace of the screw hole being arranged on attachment base
On mold core, another attachment base 1 is connect with template, the lengthwise position for the attachment base 1 being connect with template be it is fixed, lead to
The attachment base 1 being mounted on mold core to mold core applied force stress simultaneously is crossed, it is mobile in lengthwise position, and the company being connect with template
Joint chair 1 moves in the horizontal direction, when the bottom of the slot 11 of the planar section 22 and two attachment bases 1 at limit 2 both ends of angle connecting rod is flat
When face contact, occurs mechanical dead point at this time, the attachment base 1 connecting at this time with template no longer moves horizontally, after spreading, due to machinery
Dead point reason, this numerical value just only will appear a fixed number, be a determining value every time, this ensure that size.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
Protection scope within.
