Abstract
The present invention discloses a safe pressure mould which comprises a mould seat. A lower mould which is fixed to the mould seat and an upper mould which is driven by a power device and moved between top and bottom, wherein the upper mould comprises a power rod which exerts driving force to the upper mould and also has guide action, the end part of the power rod is fixedly connected with an upper mould body, the upper mould body is downwards provided with a punching head corresponding to the lower mould, and the punching head can slide between top and bottom along the power rod. Furthermore, an elasticity device is arranged between the upper mould body and the punching head, a limiting device which limit a position of top and bottom movement within certain range for the punching head corresponding to the upper mould body is arranged between the upper mould body and the punching head, and the punching head follows the upper mould to move between top and bottom to process products. When foreign objects are arranged between the punching head and the lower mould, the punching head does not downwards move, the movement of the upper mould body is counteracted by the elasticity device, and therefore, accidents are avoided occurring.
Description
Technical field
The present invention relates to a kind of pressure mould, relate in particular to a kind of pressure mould of the user's of assurance safety.
Background technology
Pressure mould comprises upper die and lower die, and what rely on patrix moves up and down converted products.But pressure mould causes industrial accident in process of production easily again and again, threatens for people's safety of life and property.Especially in the light industrial goods manufacturing, though stamping press is little, equally also can injure human body, so safety problem is also very important.
Summary of the invention
Technical problem to be solved by this invention provides a kind of safe pressure mould that has safe effect in light industry.
For achieving the above object, technical scheme of the present invention is: a kind of safe pressure mould, comprise die holder, be fixed in the counterdie on the die holder, the patrix that drives and move up and down by power set, described patrix comprises patrix is applied driving force and has the power rail of guide effect concurrently, the end of described power rail is fixedly connected with mould body, the described mould body of going up has the staking punch corresponding with counterdie, staking punch can slide up and down along power rail, be provided with elastic device between last mould body and the staking punch, also be provided with the restriction staking punch moves downward the position within the specific limits with respect to last mould body stopping means between last mould body and the staking punch.
Described elastic device is the compression spring.
Described stopping means is the gag lever post that an end and last mould body are fixed, the other end passes the staking punch body, and the end of described gag lever post is equipped with block.
Owing to adopt technique scheme, a kind of safe pressure mould comprises die holder, be fixed in the counterdie on the die holder, the patrix that drives and move up and down by power set, described patrix comprises patrix is applied driving force and has the power rail of guide effect concurrently, the end of described power rail is fixedly connected with mould body, the described mould body of going up has the staking punch corresponding with counterdie, staking punch can slide up and down along power rail, be provided with elastic device between last mould body and the staking punch, also be provided with the restriction staking punch moves downward the position within the specific limits with respect to last mould body stopping means between last mould body and the staking punch; Staking punch is followed patrix and is moved up and down, converted products; When between drift and the counterdie foreign matter being arranged, staking punch no longer moves down, and the motion of last mould body is absorbed by elastic device, can avoid taking place security incident like this.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in drawings, a kind of safe pressure mould, comprise die holder 1, be fixed in the counterdie 2 on the die holder 1, the patrix that drives and move up and down by power set, described patrix comprises patrix is applied driving force and has the power rail 3 of guide effect concurrently, the end of described power rail 3 is fixedly connected with mould body 4, the described mould body 4 of going up has the staking punch 5 corresponding with counterdie 2, staking punch 5 can slide up and down along power rail 3, be provided with elastic device 6 between last mould body 4 and the staking punch 5, described elastic device 6 is the compression spring.Also be provided with restriction staking punch 5 moves downward the position within the specific limits with respect to last mould body 4 stopping means 7 between last mould body 4 and the staking punch 5.
Described stopping means 7 is the gag lever post 71 that an end and last mould body are 4 fixing, the other end passes staking punch 5 bodies, the end of described gag lever post is equipped with block 72, what the block 72 in the present embodiment adopted is the nut that is fixed in gag lever post 71 ends, and the position of nut can be adjusted, like this with regard to the contract initial elastic force of spring of adjustable seamless, the needed minimum stamping press of this initial elastic force punching press just.
The course of work of the present invention is as follows: power rail 3 moves downward under power set drive, and mould body 4 moves downward in the drive, and staking punch 5 to counterdie 2 motions, is finished process at the effect lower edge of last mould body 4 and spring power rail 3; Power rail 3 moves upward under power set drive, and mould body 4 moves upward in the drive, and staking punch 5 is followed mould body 4 at the nut effect lower edge of gag lever post 71 ends power rail 3 and moved upward, and finishes reseting procedure, so moves in circles.When between drift and the counterdie foreign matter being arranged, staking punch no longer moves down, and the motion of last mould body is absorbed by elastic device, can avoid taking place security incident like this.
The present invention is applied to the hot drift of plastic bag making machine, plastic film gloves make-up machine, and effect is comparatively remarkable.The staking punch of this kind machinery is provided with electric heater unit, does not need too big pressure in process, can plastic sheet is bonding.If do not adopt the present invention, when foreign matter, its extruding force is very large, is enough to cause personal injury, and therefore social benefit of the present invention is very huge.
