Abstract
The utility model discloses a high -efficient cooling stool injection mold, including cover half fixed plate, cover half, core, movable mould, filler strip, ejector pin, top rod fixing plate, ejector pin backing plate, movable mould backing plate, characterized by: the core is equipped with the through -hole, the cooperation is slided in the through -hole to ejector pin one end, and the other end is fixed on top rod fixing plate and ejector pin backing plate, and the ejector pin has the core bar for hollow structure and the cooperation of sliding in inside, and the core bar head stretches out the ejector pin and lies in the through -hole, and through -hole, core bar and ejector pin surround the cavity of formation bench face installation foot, the core bar afterbody is fixed on the cover half backing plate, and the cover half backing plate is equipped with the cooling pipeline, and the inside cavity of core bar feeds through the cooling tube way. This scheme provides a stool injection mold, and the installation foot of bench face below can in time cool off, appears when avoiding the drawing of patterns pulling.
Description
Technical field
The present invention relates to a kind of high efficiency cooling stool injection mold, belong to mould applications.
Background technology
The stool face of stool and stool pin be injection moulding respectively usually, and the later stage is assembled together, and therefore the lower surface in stool face can form the mounting structure overlapping wound packages in passing and be used for coordinating stool pin when injection moulding.But when stool emaciated face mould, mounting structure easily pulls distortion because of inhomogeneous cooling even appearance.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of high efficiency cooling stool injection mold, and the installation foot below stool face can cool in time, avoids occurring pulling during the demoulding.
For achieving the above object, the invention provides following technical scheme: a kind of high efficiency cooling stool injection mold, comprise cover half fixed head, cover half, core, dynamic model, filler strip, push rod, push rod fixed head, push rod backing plate, dynamic model backing plate, it is characterized in that: described core is provided with through hole, described push rod one end slippage is engaged in through hole, the other end is fixed on push rod fixed head and push rod backing plate, push rod is hollow structure and is combined with core bar at interior slip, core bar head stretches out push rod and is positioned at through hole, through hole, core bar and push rod surround the cavity forming stool face installation foot, described core bar afterbody is fixed on cover half backing plate, cover half backing plate is provided with cooling line, core bar inner hollow is also communicated with cooling line.
Preferably, described core bar head circumference is distributed with convex tendon.
Preferably, described core bar tail end face is provided with seal groove.
Preferably, described cover half both sides are fixed with oil cylinder, and the piston rod of oil cylinder is connected on push rod backing plate.
By adopting technique scheme, cooling line is passed into core bar head cooling water by core bar inside, cools fast the cavity of stool face installation foot; Not easily damage is caused when push rod ejects; And push rod concentric embedded structure this with core bar, mold actions is coordinated compact, the demoulding is smooth.

Detailed description of the invention
A kind of high efficiency cooling stool injection mold, comprise cover half 2 fixed head, cover half 2, core 1, dynamic model 7, filler strip 3, push rod 10, push rod 10 fixed head, push rod backing plate 6, dynamic model backing plate 8, described core 1 is provided with through hole 9, described push rod 10 one end slippage is engaged in through hole 9, the other end is fixed on push rod 10 fixed head and push rod backing plate 6, push rod 10 is hollow structure and is combined with core bar 11 at interior slip, core bar 11 head stretches out push rod 10 and is positioned at through hole 9, through hole 9, core bar 11 and push rod 10 surround the cavity forming stool face installation foot, described core bar 11 afterbody is fixed on cover half backing plate 4, cover half backing plate 4 is provided with cooling line 4a, core bar 11 inner hollow is also communicated with cooling line 4a.Cooling line 4a is passed into core bar 11 head cooling water by core bar 11 inside, cools fast the cavity of stool face installation foot; Push rod 10 not easily causes damage when ejecting; And push rod 10 concentric embedded structure this with core bar 11, mold actions is coordinated compact, the demoulding is smooth.
Wherein, core bar 11 head circumference is distributed with convex tendon 10a.The convex tendon 10a of head allows installation foot can better coordinate stool pin, and stool pin not easily rotates, and convex tendon 10a can realize quick heat radiating, installation foot cool more block evenly.
Wherein, core bar 11 tail end face is provided with seal groove.Arranging seal groove can avoid cooling water to flow in mould.Cover half backing plate 4, in order to fixing core bar 11, generally will be arranged to upper and lower two pieces, if allow cooling water flow between upper and lower two pieces of backing plates, easily causes corrosion.Single solution for diverse problems limit 11a can also be set at core bar 11 afterbody, correspondingly mill out a face at cover half backing plate 4 to also corresponding on the mounting groove that core bar 11 coordinates, to block core bar 11, avoid core bar 11 to rotate.
Wherein, cover half 2 both sides are fixed with oil cylinder 5, and the piston rod of oil cylinder 5 is connected on push rod backing plate 6.Drive push rod backing plate 6 to move by oil cylinder 5, coordination, firmly evenly, ejecting product quality is good, and distortion is few.
