Abstract

The invention discloses an upper die automatic stripping device for a hot forging die. The upper die automatic stripping device for the hot forging die comprises an ejection rod, an upper template, a limit plate, a spring, a fixing plate I, a fixing plate II, through holes, an ejection rod pushing head, a bolt and an ejection rod base; the through hole is formed inside the upper template; the ejection rod is arranged inside the through hole; the spring is arranged at the upper end of the ejection rod; the fixing plate I is arranged at the top of the spring; the upper end of the fixing plate I is connected with an ejection rod base; the bolt is arranged on the ejection rod base; the limit plate is arranged at the lower end of the upper template; the through hole is formed inside the limit plate; the fixing plate II is arranged at the lower end of the limit plate; the ejection rod pushing head is arranged at the bottom of the ejection rod. According to the upper die automatic stripping device for the hot forging die, the ejection rod is arranged inside the through hole, the spring is arranged at the upper end of the ejection rod, the limit plate is arranged inside the die, the depth of the ejection rod is controlled by the limit plate, a forge piece inside stripping die is ejected out due to the downward pressure of the ejection rod base during forging and stamping, and then the forge piece which can be quickly separated from the die gets back to a normal position due to the self-counter-acting force of the force accumulated spring.

Description

A kind of hot forging die upper die automatic demolding device
Technical field
The present invention relates to a kind of patrix automatic releasing device, relate in particular to a kind of hot forging die upper die automatic demolding device.
Background technology
Along with China's industrial boom, change intensive industry at industrial structure change into by extensive industry, more and more tighter to product quality requirement, more and more lower to the requirement of product rejection rate, particularly more and more higher in reliability, the stability requirement of cold stamping quality.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of patrix automatic releasing device, relates in particular to a kind of hot forging die upper die automatic demolding device.
The present invention is achieved through the following technical solutions: a kind of hot forging die upper die automatic demolding device of the present invention, comprise push rod, cope match-plate pattern, limiting plate, spring, fixed head one, fixed head two, through hole, push rod is cut somebody's hair, bolt and tip-lever support, in described cope match-plate pattern, be provided with through hole, in described through hole, push rod is set, spring is settled in described push rod upper end, described spring top arranges fixed head one, described fixed head one upper end connects tip-lever support, and at described tip-lever support, bolt is set, described cope match-plate pattern lower end arranges limiting plate, in described limiting plate, through hole is set, described limiting plate lower end arranges fixed head two, described push rod bottom arranges push rod and cuts somebody's hair.
As preferably, described push rod is cut somebody's hair as trapezoidal.
As preferably, described spring is made as strong wear-resistant spring.
As preferably, described fixed head two is arranged on limiting plate and push rod joint.
The invention has the beneficial effects as follows: due to through hole being set in cope match-plate pattern, by being arranged on the push rod in through hole, and in push rod upper end, spring is set, in mould, be provided with limiting plate, by the degree of depth of limiting plate control push rod, in forging and stamping process, by the downward pressure of tip-lever support, forging in the demoulding is slowly backed down, forging can be separated in mould fast, the reaction force of the spring self by holding power is got back to original position.
Accompanying drawing explanation
For ease of explanation, the present invention is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is a kind of hot forging die upper die automatic demolding device of the present invention.
The specific embodiment
As shown in Figure 1, a kind of hot forging die upper die automatic demolding device of the present invention, comprise push rod 2, cope match-plate pattern 1, limiting plate 4, spring 6, fixed head 1, fixed head 23, through hole 10, push rod cuts somebody's hair 5, bolt 9 and tip-lever support 8, in described cope match-plate pattern 1, be provided with through hole 10, the interior push rod 2 that arranges of described through hole 10, spring 6 is settled in described push rod 2 upper ends, described spring 6 tops arrange fixed head 1, described fixed head one 7 upper ends connect tip-lever support 8, and at described tip-lever support 8, bolt 9 is set, described cope match-plate pattern 1 lower end arranges limiting plate 4, the interior through hole 10 that arranges of described limiting plate 4, described limiting plate 4 lower ends arrange fixed head 23, described push rod 2 bottoms arrange push rod and cut somebody's hair 5.
Wherein, described push rod cuts somebody's hair 5 for trapezoidal, and described spring 6 is made as strong wear-resistant spring, and described fixed head two is established 3 and put in limiting plate 4 and push rod 2 joints, and is fixed on push rod 2.
The invention has the beneficial effects as follows: due to through hole being set in cope match-plate pattern, by being arranged on the push rod in through hole, and in push rod upper end, spring is set, in mould, be provided with limiting plate, by the degree of depth of limiting plate control push rod, in forging and stamping process, by the downward pressure of tip-lever support, forging in the demoulding is slowly backed down, forging can be separated in mould fast, the reaction force of the spring self by holding power is got back to original position.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
