Technical field
The present invention relates to a kind of injection mold, refer in particular to a kind of injection mold with cover half angle core-pulling mechanism.
Background technology
In injection mold, the appearance surfaces of goods generally is located at cover half, makes demoulding thimble be positioned at invisible position to the thimble impression that goods produce when dynamic model takes off material.If appearance surfaces has back-off structure or the structure of loosing core, then cover half be provided with oblique top take off back-off or core-pulling mechanism will be inevitable.The existing mold structure is at cover half cover half ejector retainner plate assembly to be set, and between top clamping plate and cover half die cavity, hot flow path is set, between cover half push pedal and top clamping plate spring is set, dynamic model overcomes spring force by the ejector retainner plate release link when the mold closing cover half push pedal is killed on top clamping plate.When die sinking was finished in injection moulding, the cover half push pedal drove slide block or the Angle Pin guiding mold insert action of loosing core of loosing core under spring force promotes, and the dynamic mould core band workpiece and left the cover half die cavity and finish the die sinking action simultaneously, continues following routine and takes off the material operation.Owing to hot flow path will be set and increase cover half ejector retainner plate assembly, cause the thickness of cover half to increase greatly, and make the mould structure complexity, manufacturing cost improves.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problems, the injection mold with cover half angle core-pulling mechanism that a kind of simple in structure, dependable performance, die shape size are little, can effectively reduce die manufacturing cost is provided.
The present invention is achieved in that
A kind of injection mold with cover half angle core-pulling mechanism, comprise solid plate, cover half cavity plate, dynamic mould core and cover half angle core-pulling mechanism, described cover half angle core-pulling mechanism comprises mouth of a river plate, the spring of loosing core, spring guide pillar, big slide block, middle slide block, small slide block, positioning ball, spring guide pillar is provided with round cap, the cover half cavity plate is provided with positioning step, spring guide pillar and cover half cavity plate are slidingly connected, the both ends of the spring of loosing core connects mouth of a river plate and cover half cavity plate, big slide block be slidingly connected with middle slide block, middle slide block and small slide block are slidingly connected.
Slide block laterally is slidingly matched by square groove and cover half cavity plate in described.
Slide block laterally is slidingly matched by dovetail groove and cover half cavity plate in described.
Described big slide block is fixed on the solid plate, is slidingly matched by inclination dovetail groove and middle slide block.
Described cover half cavity plate is provided with retainer spring, and the retainer spring top is fixed with steel ball, and middle slide block is provided with the counterbore that cooperates with steel ball.
Slide block is slidingly matched by inclination dovetail groove and small slide block in described.
The present invention is by increasing a mouth of a river plate between solid plate and cover half cavity plate, the guide pillar of band spring is set between cover half cavity plate and mouth of a river plate, utilize the active force of spring to realize loosing core on the cover half during die sinking, compare with the conventional mould that increases front mould ejector retainner plate assembly with the employing hot flow path, can effectively simplify the structure of mould, obviously reduce the thickness of mould, thereby reduce manufacturing cost, have tangible economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to amplification view.
The specific embodiment
For being illustrated more clearly in technical scheme of the present invention, the present invention is further described below in conjunction with embodiment.
As shown in Figure 1, a kind of injection mold with cover half angle core-pulling mechanism, comprise solid plate 1, cover half cavity plate 4, dynamic mould core 3 and cover half angle core-pulling mechanism 2, described cover half angle core-pulling mechanism 2 comprises mouth of a river plate 211, the spring 210 of loosing core, spring guide pillar 209, big slide block 201, middle slide block 202, small slide block 212, positioning ball 205, spring guide pillar 209 is provided with round cap 207, cover half cavity plate 4 is provided with positioning step 208, spring guide pillar 209 is slidingly connected with cover half cavity plate 4, spring 210 two ends of loosing core connect mouth of a river plate 211 and cover half cavity plate 4, big slide block 201 be slidingly connected with middle slide block 202, middle slide block 202 is slidingly connected with small slide block 212.
As shown in Figure 1 and Figure 2, described middle slide block 202 laterally is slidingly matched by square groove 214 and cover half cavity plate 4.
As shown in Figure 1, described big slide block 201 is fixed on the solid plate 1, is slidingly matched by inclination dovetail groove 204 and middle slide block 202.
As shown in Figure 1, described cover half cavity plate 4 is provided with retainer spring 206, and retainer spring 206 tops are fixed with steel ball 205, and middle slide block 202 is provided with the counterbore 203 that cooperates with steel ball 205.
As shown in Figure 1, described middle slide block 202 is slidingly matched by inclination dovetail groove 212 and small slide block 211.
As shown in Figure 1, after mould is finished injection moulding, dynamic model retreats, the guide pillar spring 210 that is positioned at 4 of mouth of a river plate 211 and cover half cavity plate promotes cover half cavity plate 4 and retreats with dynamic model along spring guide pillar 209, middle slide block 202 moves together in company with cover half cavity plate 4, slide block 202 also produces laterally moving outward along inclination dovetail groove 204 simultaneously when retreating, small slide block 212 thereupon along inclination dovetail groove 213 produce oblique loose core mobile, to steel ball 205 just in time with middle slide block 202 on counterbore 203 cooperate the location, the round cap 207 of spring guide pillar 209 cooperates with the positioning step 208 of cover half cavity plate 4, the stem stem disengaging workpiece 5 that is engaged in workpiece 5 holes is finished the action of loosing core, middle slide block 202 and big slide block 201, small slide block 212 stops relative motion, spring 210 active forces of loosing core disappear, and no longer promote cover half cavity plate 4 and continue to retreat.In cover half cavity plate 4 and mouth of a river plate 211 separating process, gate waste in the mouth of a river plate 211 is pulled out from mouth of a river plate 211 owing to be fixed on the pulling of the cast gate crochet hook 6 on the solid plate 1, simultaneously the waste material in the cast gate 7 also is drawn out in the cover half cavity plate 4, and the waste material material that the material discharging rod by other setting will be bonded on the cast gate crochet hook 6 ejects outside the mould.Dynamic model continues die sinking, makes workpiece 5 break away from the cover half die cavity fully, and adopts usual manner to finish goods and take off material work.
The foregoing description is to further specify of the present invention, is not to concrete qualification of the present invention, therefore does the variation that is equal to according to the present patent application claim, is the scope that contains in the present invention.
