Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Fig. 2 and reference picture 1, a kind of mould of formed automobile glove compartment lock driven gear fixed plate, including dynamic model And cover half, include Bottom clamp plate 91, push pedal 92, the fixed plate 931 of push rod 931, cushion block 94 and dynamic in dynamic model successively from the bottom to top Template 2, and a sprue sprue puller 62 and multiple push rods 931 are fixed with the fixed plate 1 of push pedal 92, sprue sprue puller 62 is used Sprue 61 is promoted to be stripped after die sinking, push rod 931 is used to promote fixed plate 1 to be stripped after molding.In cover half from top to bottom successively Including top clamping plate 95 and solid plate 3, sprue bush 951 is provided with top clamping plate 95.

With reference to shown in Fig. 3, Fig. 5 and Fig. 6, a solid punch 4, four sides of solid punch 4 are mounted with moving platen 2 A locating piece 41 is provided with angle.One integral concave mould 5 is installed, four edges of integral concave mould 5 are equal in solid plate 3 Offer the locating slot 51 being embedded in for locating piece 41.Make solid punch 4 with the cooperation of locating slot 51, fast positioning for located piece 41 With the matched moulds of integral concave mould 5, and integral concave mould 5 and solid punch 4 cooperatively form the die cavities of two shaping fixed plates 1, so as to use The form production of the chamber of one mould two, accelerates production efficiency.And it is extended with and sprue sprue puller to die cavity direction from sprue bush 951 Sprue 61 corresponding to 62, the end of sprue 61 have two runners 95 for extending to single die cavity backwards.

Integral concave mould 5 is spliced by the first cavity plate 5a and the second cavity plate 5b, and the first cavity plate 5a has to be opened for sprue 61 If the first convex portion 5a1, the second cavity plate 5b has the first recess 5b1, and matching somebody with somebody by the first convex portion 5a1 and the first recess 5b1 Grafting is closed, and so as to quickly be spliced into integral concave mould 5, and reduces the friction of the first cavity plate 5a and the second cavity plate 5b joint places.

Solid punch 4 is spliced by the first punch-pin 4a and the second punch-pin 4b, corresponding, and the first punch-pin 4a has for leading The second convex portion 4a1 that runner sprue puller 62 is worn, the second punch-pin 4b have the second recess 4b1, and pass through the second recess 4b1 and Two convex portion 4a1 grafting coordinates, and so as to quickly be spliced into integral concave mould 5, and reduces the first convex portion 5a1 and the second convex portion 4a1 and pastes Friction at conjunction.

It is convex that the first convex portion 5a1 and second is separately positioned on by the place of opening up of sprue 61 and for the place of wearing of sprue sprue puller 62 At portion 4a1, the plastic melt in sprue 61 is avoided to enter in the gap that integral concave mould 5 or solid punch 4 splice.

First punch-pin 4a is corresponding with the first cavity plate 5a to cooperatively form a die cavity, the second punch-pin 4b and the second cavity plate 5b phases Corresponding matching forms a die cavity, and is molded at the first punch-pin 4a and the first cavity plate 5a and is located at the second punch-pin 4b and second Two fixed plates 1 being molded at cavity plate 5b are set with the axial symmetry of sprue 61, so as to reduce the volume of mould in right amount, are saved into This.

With reference to shown in Fig. 4 and Fig. 6 and reference picture 1, solid punch 4, which is located at two die cavities, is respectively equipped with a first boss 42 and a second boss 43, first boss 42 is used to be molded first connecting portion 11 in fixed plate 1, and second boss 43 is used to be molded Second connecting portion 12 in fixed plate 1, and because first connecting portion 11 is set higher than second connecting portion 12, then needed for first connecting portion 11 Plastic melt amount be more than second connecting portion 12 needed for amount, according to plastic melt flow track so that first boss 42 is set The distance that place is put apart from the cast gate of runner 95 is less than apart from the distance of the cast gate of runner 95 at the setting of second boss 43, so that it is guaranteed that Quality after first connecting portion 11 and second connecting portion 12 are molded in fixed plate 1.

Solid punch 4, which is located at two die cavities, is respectively equipped with two the first core blocks 44 and six the second core blocks 45, the One cored hole is used for the first deformation hole 15 being molded in fixed plate 1, and the second core block 45 is used for the second shape being molded in fixed plate 1 Variable orifice 16.And integral concave mould 5 is corresponding offers two the first caulking grooves 52 and six the second caulking grooves 53, through the first core block 44 and the One caulking groove 52 cooperatively forms two the first grabs 13 in fixed plate 1, is cooperatively formed through the second core block 45 and the second caulking groove 53 solid Eight the second grabs 14 in fixed board 1.

Integral concave mould 5 has two the first slots 54 positioned at two the provided circumferentially about of the place of the first caulking groove 52, positioned at two Both sides at where first caulking groove 52 are provided with two the second slots 55, and line and the second slot at the place of the first slot 54 Line at where 55 is perpendicular, and the first slot 54 is used for the jointing plate 17 being molded in fixed plate 1, and the second slot 55 is used to be molded Limiting section 18 in fixed plate 1.

With reference to shown in Fig. 7, moving platen 2 and solid plate 3 be respectively provided be embedded in respectively for solid punch 4 and integral concave mould 5 it is recessed Groove 7, the bottom surface of each groove 7 offer two necks 71, and each neck 71 each corresponds to the first punch-pin 4a, the second punch-pin 4b, the first cavity plate 5a and the second cavity plate 5b, be mounted with a magnetic block 711 in neck 71, so as to increase moving platen 2 with it is overall Connected between punch-pin 4, between solid plate 3 and integral concave mould 5 more close.

Between first punch-pin 4a and the second punch-pin 4b and moving platen 2, the first cavity plate 5a and the second cavity plate 5b and solid plate 3 it Between be provided with cooling water channel 8, and cooling water channel 8 wears the bottom surface of groove 7, for cooling down die cavity, accelerates the solidifying of plastic melt Gu.And annular groove 72 is offered in the bottom surface of groove 7 of moving platen 2 and solid plate 3, sealing ring 721 is provided with annular groove 72, is used for Be set on cooling water channel 8, prevent between solid punch 4 and moving platen 2, between integral concave mould 5 and solid plate 3 because of machining accuracy Problem causes cooling water channel 8 to cause to bend in joint place, so as to avoid bending place leak.

During using the utility model, by the first punch-pin 4a and the second punch-pin 4b through the second convex portion 4a1's and the second recess 4b1 Coordinate in embedded moving platen 2, cooperations of the first cavity plate 5a and the second cavity plate 5b through the first convex portion 5a1 and the first recess 5b1 is embedding Enter in solid plate 3, and fixed through magnetic block 711, while the first punch-pin 4a is alignd with the first cavity plate 5a, the second punch-pin 4b with Second cavity plate 5b aligns, in use, if after any one place reaches the infringement of unrepairable degree, you can removes more Change, relatively whole replacing is more cost-effective.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
