Abstract
The utility model discloses a wedged rod triangular slider type first reset mechanism. The first reset mechanism consists of a fixed die holder plate, a movable die holder plate, a fixed die plate, a movable die plate, a wedged rod, an inclined guide pillar, a side type core slider, a triangular slider, a push pipe and a push pipe fixing plate. The first reset mechanism is characterized in that the wedged rod (1) is arranged on the fixed die holder plate and then is in clearance fit with the fixed die plate and the movable die plate; an inclined surface of the wedged rod (1) is in sliding fit with that of the triangular slider (4); the inclined guide pillar (2) is arranged in an inclined hole of the fixed die plate and then is in clearance fit the side type core slider (3); and the push pipe (5) is arranged in a stepped hole of the push pipe fixing plate (6) and then is in sliding clearance fit the movable die plate.
Description
Technical field
The present invention relates to die cast metal mould and injection-moulding plastic mould, is the first resetting-mechanism of a kind of tapered bar cam block formula.
Background technology
In the mould design, avoid not bumping and interference with other part at side core and related die working part as far as possible, in order to reach this purpose, therefore must arrange in some position of mould and reset and first resetting-mechanism, reach the side core slide block like this and the mold work part resets earlier, just can avoid producing the generation of collision and interference, resetting at mould circle at present has with first resetting-mechanism: (1) spring elder generation resetting-mechanism, it is a kind of resetting-mechanism that utilizes acting force of the spring that ejecting mechanism was carried out before matched moulds, being that spring is compressed is installed between ejector pin retaining plate and the dynamic model support plate, when ejecting mechanism is started working, when the push pedal on injector or the die casting machine disengages, effect lower push-rod at the multiple Hui Li of spring resets rapidly, and in Angle Pin push rod end that just resets before driving side core slide block does not reset as yet, therefore avoided the interference of side core.Though this resetting-mechanism is simple in structure, it is convenient to install, debug, because spring force is less, and fatiguability lost efficacy, even after the spring breakage, and fragment enters mold cavity or Spring Card after death, the very easy mould groundwork part that breaks causes a complete set of mould to be scrapped.(2) tapered bar formula elder generation resetting-mechanism, it is to utilize tapered bar to promote to be installed in a kind of method of the roller drive liftout plate forced resetting on the fork, though it moves solid and reliable, but it is extremely inconvenient in the installation of mould, debugging, maintenance, roller stress is bigger simultaneously, very easily wearing and tearing are broken, and cause the mold damage part.In order to overcome the deficiency of above-mentioned two kinds of resetting-mechanisms, I am in conjunction with mould field work experience, and the spy provides following a kind of novel mechanism to address the above problem.
Summary of the invention
The present invention provides the first resetting-mechanism of a kind of tapered bar cam block formula, it is achieved in that tapered bar is fixed in the cover half, cam block is installed in the guide runner of ejector sleeve fixed head, when matched moulds, tapered bar still contacts with the inclined-plane of cam block, since tapered bar and cam block contact contacting prior to Angle Pin and side core slide block, under the effect of tapered bar, when moving down, the cam block in the guide runner on the ejector sleeve fixed head force the ejector sleeve fixed head to move right, make resetting prior to the resetting of side core slide block of ejector sleeve, thereby avoid both to interfere.It has solved spring elder generation resetting-mechanism the first resetting-mechanism of a kind of tapered bar cam block formula, and spring strength is less, and fatiguability lost efficacy, even after the spring breakage, fragment enters mold cavity or Spring Card after death, breaks mould groundwork part, the problem that causes a complete set of mould to be scrapped.Solve tapered bar formula elder generation resetting-mechanism mould and installed, debug, keeped in repair inconvenient problem.It is bigger to have solved roller stress simultaneously, and very easily wearing and tearing are broken, and cause the problem of mold damage part.The first resetting-mechanism of a kind of tapered bar cam block formula is characterized in that: tapered bar (1) is installed on the top clamping plate, cooperate with solid plate and moving platen glade plane space then, the inclined-plane of tapered bar (1) becomes to be slidingly matched with the inclined-plane of cam block (4), Angle Pin (2) is installed in the inclined hole of solid plate and then with side core slide block (3) and becomes matched in clearance, and ejector sleeve (5) is installed in the stepped hole of ejector sleeve fixed head (6) and becomes glade plane space to cooperate then with moving platen.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing
Fig. 1 is the sectional side elevation of the first resetting-mechanism matched moulds of a kind of tapered bar cam block formula state.
Sectional side elevation when Fig. 2 is the resetting-mechanism die sinking of a kind of tapered bar cam block formula elder generation.
Numeral number is represented respectively among the figure:
1---tapered bar 2---Angle Pin 3---side core slide block
4---cam block 5---ejector sleeve 6---ejector sleeve fixed heads
The specific embodiment:
It is the first resetting-mechanism of a kind of tapered bar cam block formula shown in the figure.Tapered bar is fixed in the cover half, cam block is installed in the guide runner of ejector sleeve fixed head (6), and at the matched moulds state, tapered bar (1) still contacts with the inclined-plane of cam block (4), beginning is during matched moulds, tapered bar and cam block contact contacting prior to Angle Pin and side core slide block (3).Under the tapered bar effect, when moving down, the cam block (4) in the guide runner on ejector sleeve fixed head (6) force ejector sleeve fixed head (6) to move right, make resetting prior to the resetting of side core slide block (3) of ejector sleeve (5), thereby avoid both to interfere.
Claims (1)
1. a tapered bar cam block formula elder generation resetting-mechanism is characterized in that: tapered bar (1) is installed on the top clamping plate, cooperate with solid plate and moving platen glade plane space then, the inclined-plane of tapered bar (1) becomes to be slidingly matched with the inclined-plane of cam block (4), Angle Pin (2) is installed in the inclined hole of solid plate and then with side core slide block (3) and becomes matched in clearance, and ejector sleeve (5) is installed in the stepped hole of ejector sleeve fixed head (6) and becomes glade plane space to cooperate then with moving platen.
