Abstract
The utility model belongs to the field of moulds, and particularly relates to a mould locking device which comprises two slider angle pins, a slide block and four mould cores, wherein a fixed groove is formed in each mould core and connected with the slide block, a locking groove is formed in each mould core, and an adjacent mould core is provided with a locking edge which is matched with the locking groove. In moulds, the four mould cores form a four-side loose core. The two slider angle pins are arranged on the slide block so as to be used for increasing the movement stability of the slide block. According to the mould locking device provided by the utility model, after the mould is closed, the mould cores bear locking forces in two directions besides bearing a limit pressure of the slide block because the locking edges on the adjacent mould cores are matched with the locking grooves, and the risk of separation of the moulds due to overlarge injection pressure is eliminated.
Description
Technical field
The utility model belongs to mould applications, is specifically related to a kind of mold locking device.
Background technology
Along with social productive forces improve, the output of commodity production can be increasing, and traditional single and mini-batch production production can not satisfy social needs.In production in enormous quantities, it is essential that mould uses, and at the plastic products production field, injection mold uses very common, simultaneously to some non-ferrous metals, also adopts die casting to carry out die casting production.For some complex-shaped plastic products or die cast product, the demoulding smoothly during for convenient production can be used various loosing core, slide block.The form that requires height or outer surface the plastic products of sunken inside or die cast product to be arranged even can adopt mold cavity to loose core on four sides to a part of surface quality.Because mould is when work, die cavity can bear higher injection pressure, all retaining mechanism can be set above the mould movable block, to guarantee mould each slide position in the course of the work, guarantees the die cavity integrality.Loose core in the mould in present four sides, the slide block locking mechanism mostly is folk prescription to fixing, when mold injects pressure is excessive, and the risk that can exist slide block to separate.
The utility model content
A kind of mould locking mechanism that the utility model provides at above-mentioned weak point can lock the four sides mould of loosing core, and behind the mould matched moulds, the four directions slide block of loosing core is lockable, and slide block can not separate.
The utility model is achieved in that a kind of mold locking device, comprises Angle Pin, slide block, and core rod arranges holddown groove and is connected with slide block on the core rod, locking slot is set on the core rod, and adjacent core rod arranges the locking rib and cooperates with the above locking slot.In mould, core rod is established four formation four sides and is loosed core.Angle Pin is set on the slide block arranges two, in order to increase the stationarity of slide block movement.
Mold locking device of the present utility model, after the mould matched moulds, core rod is except being subjected to the spacing pressure of slide block, and the locking rib on the adjacent core rod cooperates with locking slot, make core rod that coupling mechanism force all be arranged on both direction, get rid of the risk that mould separates because injection pressure is excessive.

Fig. 2 is the utility model left view.
Fig. 3 is the utility model schematic perspective view.
Fig. 4 is the utility model core rod schematic perspective view.
In the accompanying drawing: the 1-Angle Pin, the 2-slide block, the 3-core rod, 4-locks rib, 5-locking slot, 6-holddown groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail; but the utility model is not limited to following embodiment; any change of making on the present embodiment principle or replacement scheme all fall among the claimed scope of the utility model.
1-Fig. 4 by reference to the accompanying drawings, a kind of mold locking device comprises Angle Pin 1, slide block 2, core rod 3 arranges holddown groove 6 and is connected with slide block 2 on the core rod 3, locking slot 5 is set on the core rod 3, and adjacent core rod 3 arranges locking rib 4 and cooperates with the above locking slot 5.In mould, core rod 3 is established four formation four sides and is loosed core.Angle Pin 1 is set on the slide block 2 arranges two, in order to increase the stationarity of slide block 2 motions.
In use, mould is when matched moulds, and core rod 3 is close to the mould middle part under slide block 2 drives, and core rod 3 is combined the formation mold cavity.In the course of the work, if injection pressure is excessive, just get core rod 3 possibility is separately arranged.Cooperate with locking slot 5 by the locking rib 4 on the adjacent core rod 3, it is spacing mutually to make that core rod 3 can also cooperate with locking slot 5 by locking rib 4 except spacing by slide block 2, the risk that the eliminating mould separates because injection pressure is excessive.
Claims (3)
1. a mold locking device comprises Angle Pin (1), slide block (2), core rod (3), holddown groove (6) is set on the core rod (3) is connected with slide block (2), it is characterized in that arranging on the core rod (3) locking slot (5), adjacent core rod (3) arranges locking rib (4) and cooperates with the above locking slot (5).
2. mold locking device according to claim 1 is characterized in that core rod (3) establishes four.
3. mold locking device according to claim 1 is characterized in that the last Angle Pin (1) of slide block (2) arranges two.
