Description

Fork first resets mold mechanism
Technical field
The present invention relates to die cast metal mould and plastic injection moulding mould, is that fork first resets mold mechanism.
Background technology
Reposition first is for avoiding some part in ejecting mechanism and mould not interfere in return matched moulds process, therefore needing to arrange reposition first.The reposition first adopted in existing mold has following several version: 1. spring reposition first, it utilizes spring force to make liftout plate return, though this mechanism's structure is simple, but the elastic force of spring sufficiently, if after spring failure, the part that mould planted agent first resets can not return, therefore causes the problem of mold damage groundwork part.2. excellent power glue reposition first, it utilizes return pin card to install excellent power glue, and thimble or pitched ejection mechanism are first resetted a bit of distance, this mechanism structure is simple, but safety coefficient is extremely low, during return, thimble and oblique top very easily bump against on mold cavity, cause mold cavity to be scrapped.3. the first return mechanism of wedge block, when it is matched moulds, the return bar be fixed on cover half first encounters wedge, guide runner on wedge block and push rod fixed head horizontally slips, because even 45 degree of inclined-planes, wedge block two sides are under return bar impetus, one direction moves right, when the opposing party makes again push rod fix, the revert action of push rod terminates, the return Time dependent of push rod is in the length of return pin, therefore plate be linked back push rod produce revert action, when 45 degree of inclined-planes of 45 degree of inclined-plane total detachment wedge blocks of return bar, the length of return pin makes the push rod of the interference of generation first exit interference position, this mechanism wedge is unsuitable excessive, the stroke that push rod is first return is less, mold mechanism is complicated simultaneously.In order to overcome the deficiency of above-mentioned reposition first, spy provides following a kind of reposition first to solve the deficiency of above-mentioned mold mechanism.
Summary of the invention
The present invention is to provide fork and first resets mold mechanism, it is when mould matched moulds, the return pin (13) utilizing the fork (10) being arranged on cover half one side to promote to install dynamic model one side drives thimble (14) the first return be arranged on ejector retainner plate (12), to collide mold damage die cavity and a kind of reposition first of arranging to avoid thimble (14) and cavity plate (9).The invention has the beneficial effects as follows: its mechanism is simple, and action is solid and reliable, Making mold, installation, debugging, easy to maintenance; Fork first resets mold mechanism, solves the problem of mold damage after spring reposition first spring failure.Solve excellent power glue reposition first safety coefficient low, the problem that thimble or oblique top and die cavity collide.Solve wedge block reposition first complex structure, the little problem of stroke first return by push rod.Fork first resets mold mechanism, it is characterized in that: it comprises fixed half and moving half two parts, cover half part is by cavity plate (9), pin (6), spring (7), fork (10), guide pillar (5), first screw (16) forms, described fork (10) the first screw (16) is movably connected on the side of cavity plate (9), the large end of fork (10) offers a through hole, pin (6) is fastened on the side of cavity plate (9), pin (6) is provided with a through hole, described spring (7) one end is connected on the through hole on fork (10), the other end is connected on the through hole of pin (6), described guide pillar (5) is arranged in the stepped hole of cavity plate (9), the front end of guide pillar (5) is positioned at moving platen (4), dynamic model backing plate (3), in the hole of mould pin (2), the medial surface E place of described fork (10) and the first straight pin (11) sliding connection, dynamic model part is by moving platen (4), dynamic model backing plate (3), mould pin (2), Bottom clamp plate (1), second screw (15), thimble (14), second straight pin (13), ejector retainner plate (12), first straight pin (11) forms, described moving platen (4) and cavity plate (9) form the forming cavity of goods, moving platen (4) below is provided with dynamic model backing plate (3), dynamic model backing plate (3) below is provided with mould pin (2), mould pin (2) below is provided with Bottom clamp plate (1), described moving platen (4), dynamic model backing plate (3), mould pin (2), Bottom clamp plate (1) the second screw (15) is fastenedly connected, ejector retainner plate (12) is provided with thimble (14) and the second straight pin (13), described thimble (14) is through dynamic model backing plate (3) and moving platen (4), end face and the goods (8) of thimble (14) are close to, when the medial surface E of described fork (10) is in conjunction and the second straight pin (13) be close to, described first straight pin (11) is fastened in the hole of dynamic model backing plate (3) side.

Detailed description of the invention
That fork first resets mold mechanism as shown in the figure, it is that the second straight pin (13) drive thimble (14) utilizing the fork (10) being arranged on stationary mould for mould one side to promote to be arranged on dynamic model one side when matched moulds first returns to matched moulds situation, avoids the end face of thimble (14) and cavity plate (9) to collide mold damage and a kind of reposition first of arranging.Its operating principle is: after die sinking ejects goods (8), because thimble (14) stretches out the profile of moving platen (4), in order to avoid close time thimble (14) end face and cavity plate (9) in forming recess collide, therefore fork (10) is devised, when matched moulds, the end face of the small end of fork (10) and the end contact of the second straight pin (13), so the propulsive thrust of fork (10) forces the second straight pin (3) to drive to be arranged on the thimble (14) that ejector retainner plate (12) is and first to return matched moulds situation, when ejector retainner plate (12) drives thimble (14) to be returned to matched moulds situation, and dynamic model part continues to draw close to cover half, now, because ejector retainner plate (12) drives thimble (14) to complete reset, can not action again, so the end face of fork (10) is separated with the end face of the second straight pin (13), fork (10) does downslide action along the outer surface of the second straight pin (13) under the pulling of spring (7).Continue matched moulds, until cavity plate (9) and moving platen (4) just carry out the moulding by casting in next cycle after closing.
