Abstract
The utility model discloses a novel lower collecting pipe forming mould structure. The novel lower collecting pipe forming mould structure comprises an upper mould (1) and a lower mould (2). The lower end of the upper mould (1) is located inside a mould cavity of the lower mould (2), an ejector block (3) is further arranged inside the mould cavity of the lower mould (2), and the bottom portion of the ejector block (3) is connected with the upper end of an ejector rod (4). The novel lower collecting pipe forming mould structure is characterized in that the lower end of the ejector rod (4) is installed on a supporting plate (7) and a plurality of nitrogen springs (8) are arranged below the supporting plate (7). The novel lower collecting pipe forming mould structure is simple and practical in structure, high in finished product ratio, high in forming speed, low in cost, low in requirement for equipment, capable of being used in equipment without a lower ejector cylinder, and applicable to a punch press. Besides, the stripping speed is shortened to be within one second from 3-4 seconds which is the stripping speed of the lower ejector cylinder. Production efficiency is improved by 40.5%.
Description
Technical field
The utility model relates to a kind of novel down set pipe formation die structure of signing an undertaking, and is applied to the auto parts machinery technical field.
Background technology
The upper set pipe that is applied to auto parts machinery at present all is that employing is flat-plate molded, earlier flat board is welded into cast after curved, and seven pairs of moulds are squeezed into the following concetrated pipe that needs about using by nine procedures again.This kind mould molding procedure is many, length consuming time, shaped article intensity a little less than, difficult quality guarantee, yield rate is low, the production cost height.
Chinese patent ZL200920308661.5 discloses a kind of concetrated pipe tube type material molding structure down, though saved the shaping raw material cost, but this project still has the following disadvantages: one, owing to only adopt push rod to take off material, mould only is applicable to down the hydraulic press of taking blame for others, and requires too high to equipment; Two and the action form of fluid pressure type to take off material slower, become the bottleneck in the production; Three, because oil hydraulic system is subjected to factor affecting such as fluid viscosity, environment temperature, cause same batch of uniformity of product relatively poor.
Summary of the invention
The purpose of this utility model then is at present the deficiencies in the prior art, the novel pipe formation die of set down that provides that a kind of new structure is simple, shaping speed is fast, yield rate the is high structure of signing an undertaking.
The technical solution adopted in the utility model is as follows:
A kind of novel down set pipe formation die structure of signing an undertaking, it includes upper die and lower die, the lower end of patrix is positioned at the die cavity of counterdie, also be provided with jacking block in the die cavity of counterdie, the jacking block bottom links to each other with the push rod upper end, the lower end that it is characterized in that described push rod is installed on the gripper shoe, and the below of described gripper shoe is provided with a plurality of nitrogen springs.
The quantity of described nitrogen spring is four, and they equate apart from the distance of push rod.
The madial wall bottom of described counterdie die cavity is provided with vertical locating slot, and the lateral wall of jacking block fixedly has positioning pin column, and the positioning pin column external end head is positioned at vertical locating slot.
The beneficial effects of the utility model have:
The utility model is simple and practical, the yield rate height, and shaping speed is fast, cost is low, to equipment require lowly, can use at the equipment of not taking blame for others down, may be used on punch press, take off and shortened within 1 second in 3 ~ 4 seconds that material speed takes off material by taking blame for others down, production efficiency improves 40.5%.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with drawings and Examples:
As shown in Figure 1, it includes patrix 1 and counterdie 2 the utility model, and the lower end of patrix 1 is positioned at the die cavity of counterdie 2, also is provided with jacking block 3 in the die cavity of counterdie 2, and jacking block 3 bottoms link to each other with push rod 4 upper ends.The lower end of push rod 4 is fixedly mounted on the gripper shoe 7, and the below of gripper shoe 7 is provided with a plurality of nitrogen springs 8, forms the Lifting Device of mould self.The pressure needs that the utility model uses according to reality, determine the usage quantity of nitrogen spring 8, generally quantity is arranged on more than two, be preferably four, they are evenly arranged in the bottom of gripper shoe 7, each nitrogen spring 8 equates with the distance of push rod 4, makes the pressure distribution balance on top.Usually tend to adopt more nitrogen spring with lower pressure to realize purpose.
The utility model is provided with vertical locating slot 5 in the madial wall bottom of counterdie 2 die cavitys, and the lateral wall of jacking block 3 fixedly has positioning pin column 6, and positioning pin column 6 external end heads are positioned at vertical locating slot 5, can be unlikely to dislocation in the process that jacking block 3 is lifted.
The utility model is when work, cast spare is positioned on the interior jacking block 3 of counterdie 2 die cavitys, patrix 1 presses down, cast spare is shaped to down concetrated pipe, patrix 1 lifts afterwards, push rod 4 under the effect of nitrogen spring 8 piston rods with jacking block 3 and on product eject, take out product after, push rod 4 drives jacking block 3 and falls, and enters next working cycles.
Other undeclared part that the utility model relates to is same as the prior art.
Claims (2)
