Inject in annular chamber, after a period of time, finished product cushion rubber can be prepared by opening mould.However, this processing method belongs to heat
Processing, need to carry out, there are the defects of low production efficiency at high operating temperatures.In addition when taking out finished product cushion rubber upwards, cushion rubber is thick
Degree is elongated, in uneven thickness, there are machining accuracy it is low the defects of.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the prior art, there is provided one kind is compact-sized, shaping efficiency is high, adds
High, the easy to operate press fitting belt pulley cushion rubber molding die of work precision.
The purpose of this utility model is achieved through the following technical solutions：One kind press fitting belt pulley cushion rubber molding die,
It includes upper die and lower die, and the lower die includes base connected in sequence, first boss and second boss from lower to upper, and first
Formed with first annular shoulder between boss and base, formed with the second annular shoulder, institute between second boss and first boss
State on first annular shoulder and be sequentially arranged the first product holding tank annular in shape and the more than first glue groove towards its outer edge direction,
The junction of first product holding tank and the more than first glue groove is wedge angle, and annular in shape first is provided with second annular shoulder
It is raised；The bottom of the upper mold offers stepped hole, and edge direction, which has been sequentially arranged, on the step surface of stepped hole and outwardly is in
The junction of cricoid more than second glue groove and the second product holding tank, the more than second glue groove and the second product holding tank is wedge angle, the
More than two glue grooves are engaged with the first protrusion, and the second product holding tank is located at directly over the first product holding tank, the bottom face of upper mold
On be provided with annular in shape second raised, second raised is engaged with the more than first glue groove；The macropore of the stepped hole is highly big
In the height of first boss.
More than first glue groove and the both sides of the edge of the more than second glue groove offer chamfering.
Base, first boss and the second boss is coaxially disposed.
More than first glue groove and the cross section of the more than second glue groove are toroidal.
The bottom of the second boss and anti-snap gauge opening annular in shape is provided with its cylinder.
Chamfering is offered on the edge at the top of the second boss.
The utility model has the following advantages：The utility model is compact-sized, shaping efficiency is high, high precision machining, operation
Simply.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure, 1- bases, 2- first boss, 3- second boss, the first annular shoulders of 4-, the second annular shoulders of 5-, 6-
One product holding tank, the more than first glue grooves of 7-, 8- first is raised, 9- stepped holes, the more than second glue grooves of 10-, and the second products of 11- accommodate
Groove, 12- second is raised, the anti-snap gauge openings of 13-, 14- finished product cushion rubbers.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of press fitting belt pulley cushion rubber molding die, it includes upper die and lower die, and upper mold is adopted with lower die
With clearance fit, the lower die includes base 1 connected in sequence, first boss 2 and second boss 3 from lower to upper, base 1,
First boss 2 and second boss 3 are coaxially disposed, and chamfering, first boss 2 and bottom are offered on the edge at the top of second boss 3
Formed with first annular shoulder 4 between seat 1, formed with the second annular shoulder 5 between second boss 3 and first boss 2, described the
The first product holding tank 6 annular in shape and the more than first glue groove 7 are sequentially arranged on one annular shoulder 4 and towards its outer edge direction,
The junction of first product holding tank 6 and the more than first glue groove 7 is wedge angle, is provided with second annular shoulder 5 annular in shape
First protrusion 8；The bottom of the upper mold offers stepped hole 9, and on the step surface of stepped hole 9 and edge direction is sequentially set outwardly
It is equipped with the more than second glue groove 10 annular in shape and the second product holding tank 11, the friendship of the more than second glue groove 10 and the second product holding tank 11
It is wedge angle to meet place, and the more than second glue groove 10 is engaged with the first protrusion 8, and the second product holding tank 11 is located at the first product holding tank 6
