Description
Technical field
The present invention relates to injection mold technical field, be specially a kind of injection mold with high intensity ejection pitched roof.
Background technology
Mould is indispensable important tool in injection mo(u)lding. Injection mo(u)lding is to inject the plastic material of hot melt state in mould at a high speed to have in the airtight die cavity of required form, treats plastic material cooling curing, opens mould and ejected by the plastic cement products of solidification, with the processing method obtaining shaped article. Owing to injection mo(u)lding processing method has, molding expense is low, molding cycle is short, forming process is simple and is prone to the features such as the complicated plastic cement products of forming shape, therefore extremely wide in the application of plastic cement products application. Development along with industry, constantly weeding out the old and bring forth the new of product, its structure correspondingly becomes increasingly complex, and on plastic cement products, is substantially all interior back-off structure more or less, the depanning of this interior back-off generally all adopts oblique top depanning, therefore, the requirement of pitched roof mechanism of mold is just more and more higher, produce upper use its pitched roof mechanism of mould now and be all set directly on ejector retainner plate, by the thimble presumption to ejector retainner plate, the interior back-off that pitched roof mechanism realizes product is made to go out modulo operation.
In order to meet the needs of product structure, product needed uses lifter ejection, and oblique top size is smaller relative to mould, and motion intensity in a mold is low, causes unreasonable structure. Oblique top is square lifter, and what afterbody connected is angle ejector rod. Wherein problem in big mould due to the oblique top too high length causing angle ejector rod of too little mould, so lifter ejection insufficient strength, oblique top bending drop when causing ejecting. Thus, the structure of existing oblique top injection mold needs to improve.
Summary of the invention
The purpose of invention: in order to overcome above deficiency, a kind of injection mold with high intensity ejection pitched roof of disclosure, have simple in construction, reasonable in design, eject that intensity is big, save the advantages such as cost.
Technical scheme: in order to realize object above, the invention discloses a kind of injection mold with high intensity ejection pitched roof, and including mavable module core, moving platen, oblique top head, angle ejector rod, mould foot and bottom plate, described mavable module core is located at inside moving platen;Described angle ejector rod includes interconnective end push rod and afterbody push rod; The diameter of described afterbody push rod is more than end push rod; Described oblique top head is located at the top of end push rod; Described oblique top head is cased with mold insert; The bottom of described moving platen is provided with inclined top guide block; Described mould foot is located at the both sides of bottom plate; Described moving platen is located at the top of mould foot; Described bottom plate is provided with lower ejector retainner plate; Described lower ejector retainner plate is provided with tilted footstock; Oblique top wiper it is provided with inside described tilted footstock; Described angle ejector rod is fixed on the oblique top fixed block of oblique top wiper by angle ejector rod fixed screw; Described lower ejector retainner plate is provided with the upper ejector retainner plate that can fix tilted footstock; Described angle ejector rod is on moving platen and only needs inclined top guide block fixed guide, all the other empty avoidings.
Present configuration is simple, reasonable in design, angle ejector rod is divided into end push rod and afterbody push rod, and the diameter of afterbody push rod is more than end push rod, it is ensured that slanted ejecting mechanism eject intensity, it is to avoid the phenomenon that angle ejector rod fractures occurs. It addition, adopt mold insert that oblique top head wraps in the scheme of inside, it is ensured that oblique top has enough reasonably assembling, sealing, guiding to eject face in rear mold. On described moving platen, angle ejector rod only needs inclined top guide block fixed guide, all the other empty avoidings, it is ensured that angle ejector rod can be installed smoothly when assembling; Meanwhile, present configuration is simple, cost is low, has the very big market competitiveness.
Further, above-mentioned a kind of injection mold with high intensity ejection pitched roof, described oblique top head and end push rod are integral type structure. Adopt the integrated design of oblique top head and angle ejector rod, ensure that the globality of structure, oblique top head for being limited mainly by force, the design of integration, the internal shear power each other between parts can be reduced, be unlikely in motor process, occur, owing to internal stress is excessive, phenomenon of rupture occurs.
Further, above-mentioned a kind of injection mold with high intensity ejection pitched roof, described mavable module core is provided with the installing hole matched with mold insert. Ensure that mold insert can compare to coordinate with mavable module core closely, it is ensured that oblique top head has enough reasonably sealing, guiding to eject face, is further ensured that the machining accuracy of injection mold.
Further, above-mentioned a kind of injection mold with high intensity ejection pitched roof, it is provided with the through hole matched with angle ejector rod inside described moving platen. Avoid the occurrence of angle ejector rod and interference occurs in motor process, affect the machining accuracy of mould.
Further, above-mentioned a kind of injection mold with high intensity ejection pitched roof, described oblique top fixed block is concave. The design of concave so that angle ejector rod can compare and firmly be connected with oblique top wiper, it is ensured that have sufficiently large contact point, it is ensured that the structural stability of ejecting mechanism.
Technique scheme is it can be seen that a kind of injection mold with high intensity ejection pitched roof of the present invention has the advantages that
Described a kind of injection mold with high intensity ejection pitched roof of the present invention, simple in construction, reasonable in design, angle ejector rod is divided into end push rod and afterbody push rod, and the diameter of afterbody push rod is more than end push rod, what ensure that slanted ejecting mechanism ejects intensity, it is to avoid the phenomenon that angle ejector rod fractures occur. It addition, adopt mold insert that oblique top head wraps in the scheme of inside, it is ensured that oblique top has enough reasonably assembling, sealing, guiding to eject face in rear mold. On described moving platen, angle ejector rod only needs inclined top guide block fixed guide, all the other empty avoidings, it is ensured that angle ejector rod can be installed smoothly when assembling; Meanwhile, present configuration is simple, easy to assembly, reduce cost of labor, has the very big market competitiveness.
