For realizing above-mentioned purpose, the large size, thin walled cone barrel product molding device that the utility model designed comprises patrix that small end is downward and the counterdie that matches with it.Said patrix top is fixed with cope match-plate pattern, and the below of said counterdie is fixed with lower bolster.Said counterdie top is provided with the inner cone section; Be provided with the stripper plate that is connected with patrix between said patrix and the counterdie, the inner ring of said stripper plate cooperates with the upper gap of patrix, the inner cone section cone match of the male cone (strobilus masculinus) of said stripper plate and counterdie; Said stripper plate is provided with demoulding screw, and said patrix and counterdie inside are provided with electrothermal tube.
Further, product takes out in counterdie for ease, and said counterdie bottom set inside has backing-out punch, and said lower bolster correspondence with it is provided with push rod.
Again further, relative position during for assurance upper die and lower die mold pressing operation, the upper surface of said counterdie is provided with the guide finger that upwards runs through stripper plate and cope match-plate pattern.As preferably, accurate for guaranteeing the circumferential orientation of upper die and lower die, said guide finger is set to two, and the diameter of two guide fingers does not wait.
Further, in order to guarantee the product thermally equivalent, the electrothermal tube that is provided with in said patrix and the counterdie is arranged in the vertical direction dislocation along circumferentially evenly arranging.
The advantage of the utility model is: the large size, thin walled cone barrel product molding device that is designed adopts the downward patrix of small end, adopts repeatedly reinforced method, whenever adds a defective material patrix and presses down once.Through the stripper plate inner ring cooperate with the upper gap of patrix, the inner cone section cone match of male cone (strobilus masculinus) and counterdie can guarantee the axiality of patrix and counterdie, positioning accuracy is high; Through demoulding screw is set on stripper plate, set inside backing-out punch and push rod in the counterdie bottom, the taking-up when being convenient to product respectively with patrix or counterdie adhesion, simple to operation; Through electrothermal tube rationally is set in upper die and lower die, make the electrothermal tube that is provided with in patrix and the counterdie along circumferentially evenly arranging, arrange in the vertical direction dislocation, can avoid local temperature too high, guarantee the uniformity that product is heated.
Description of drawings
Fig. 1 is the structural representation of the large size, thin walled cone barrel product of the utility model molding device.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
Large size, thin walled cone barrel product molding device shown in the figure comprises downward patrix of small end 5 and the counterdie 7 that matches with it, and patrix 5 tops are fixed with cope match-plate pattern 1 through sunk screw, and the below of counterdie 7 is fixed with lower bolster 10 through sunk screw.Counterdie 7 tops are provided with inner cone section 7a, are provided with stripper plate 4 between cope match-plate pattern 1 and the counterdie 7, stripper plate 4 through sunk screw be connected with cope match-plate pattern 1.The inner ring 4a of stripper plate 4 cooperates with the upper gap of patrix 5, and the inner cone section 7a cone match of the male cone (strobilus masculinus) 4b of stripper plate 4 and counterdie 7 guarantees monolateral gap 0.1～0.15mm, guarantees that patrix 5 and counterdie 7 are coaxial and has avoided gnawing the generation of mould phenomenon.Stripper plate 4 is provided with demoulding screw 2, when product 6 solidified posterior synechias in 5 last times of patrix, unclamps the sunk screw that connects cope match-plate pattern 1 and stripper plate 4, turns demoulding screw 2 stripper plate 4 is moved down, and product 6 is separated with patrix 5.
Patrix 5 is provided with electrothermal tube 8 with counterdie 7 inside; The concrete mode that electrothermal tube 8 is arranged in patrix 5 and counterdie 7 is: in patrix 5, be provided with 7 electrothermal tubes 8; The electrothermal tube 8 that is positioned at patrix 5 centers sinks down into the head of patrix 5, guarantees the even heating of patrix 5.12 electrothermal tubes 8 have respectively been arranged in the upper and lower of counterdie 7; And the electrothermal tube 8 on top staggers with electrothermal tube 8 circumferential positions of bottom; Corresponding top electrothermal tube 8 vertically keeps 30～50mm spacing with bottom electrothermal tube 8, avoids local temperature higher, guarantees counterdie 7 temperature homogeneities.In the practical operation, twine asbestos cord at the outer wall of counterdie 7 and be incubated.
Counterdie 7 bottom set inside have backing-out punch 9, and said lower bolster 10 correspondence with it is provided with push rod 11.When product 6 during with counterdie 7 adhesions, be about to backing-out punch 9 on the push rod 11 upwards push, product 6 is separated with counterdie 7.
Relative position when operating with counterdie 7 mold pressings for assurance patrix 5, the upper surface of counterdie 7 are provided with the guide finger 3 that upwards runs through stripper plate 4 and cope match-plate pattern 1.Guide finger 3 is set to two, and the diameter of two guide fingers 3 do not wait, and can guarantee the relative bearing of patrix 5 and counterdie 7.
When application the utility model carries out product 6 mold pressings; Give electrothermal tube 8 energisings of patrix 5 and counterdie 7 earlier, temperature reaches back outage about 75 ℃, in the die cavity of counterdie 7, adopts repeatedly reinforced method; Whenever add a defective material, the forcing press top shoe drives patrix 5 and material is compressed compacting downwards.Product 6 has under the situation of insert 6a, when near binder preformed to insert 6a position, insert 6a is set on the outer cone of patrix 5, relies on the tram of the cone match assurance insert 6a of insert 6a and patrix 5.Continuation is reinforced in the die cavity of counterdie 7, when reinforced satisfy technological requirement after, switch on for the electrothermal tube 8 of patrix 5 and counterdie 7 once more, temperature is risen to about 175 ℃ of technological requirement, carry out heat preservation solidification.After heat preservation solidification was accomplished, with electrothermal tube 8 outages of patrix 5 and counterdie 7, it is up that the forcing press top shoe drives patrix 5, observes product 6 and patrix 5 or counterdie 7 adhesion situation, accomplishes the demoulding through demoulding screw 2 or backing-out punch 9.
