Abstract
The utility model belongs to the technical field of dies, and provides a core-pulling mechanism for a front die. The core-pulling mechanism for the front die comprises a main body plate, as well as a core-pulling insert, a limit column, a die locker and/or an elastic colloid which are arranged in the main body plate, wherein the core-pulling insert, the limit column and the elastic colloid stretch out of one surface of the main body plate, and the die locker stretches out of the other opposite surface of the main body plate; during die closing, the main body plate is arranged in a front die blank and the top of the main body plate is level with the front die blank, the die locker is inserted in a stripper plate, the elastic colloid is inserted in the front die blank, and the core-pulling insert penetrates through a cavity and resists a product. The core-pulling mechanism for the front die is simple in structure, low in cost, easy to machine and assemble, high in stability, simple in operation process and high in production efficiency.
Description
Technical field
The utility model relates to the mould knock-out gear, relates in particular to a kind of front mold core-pulling mechanism.
Background technology
Because product function and structural requirement, the more difficult demoulding in mould front mould glue position of some plasthetics in the reality (being the very easily sticking front mould of plastic cement products), thereby cause plastic cement products to be difficult to from mould, to take out or because gluing front mould product is drawn distortion, such as common double color mould product and soft rubber sleeve product etc.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of front mold core-pulling mechanism is provided.
For realizing above purpose, the technical solution adopted in the utility model is:
A kind of front mold core-pulling mechanism, comprise main board and be arranged among the mold insert of loosing core, limited post, mode locker and/or elastic force colloid, the one side that the mold insert of loosing core, limited post and elastic force colloid stretch out main board, mode locker stretches out another opposite face of main board; During matched moulds, main board be arranged in the front mold base and the top concordant with it, mode locker is inserted in the water gap plate, the elastic force colloid is inserted in the front mold base, it is beautiful and prop up goods that the mold insert of loosing core passes front mould.
The described mold insert of loosing core is arranged in the main board and by the pipe nail and fixes.
The stroke S of described limited post in main board is 1.0-2.0mm.
The beneficial effects of the utility model: simple in structure, cost is low, and process and assemble is easy, and stability is high; Operating process is simple, and production efficiency is high.

The specific embodiment
Referring to Fig. 1-Fig. 6, a kind of front mold core-pulling mechanism 20 of mould comprises main board 21 and is arranged at elastic force colloid 22 wherein, the mold insert 23 of loosing core, mode locker 24 and limited post 26.Elastic force colloid 22, loose core mold insert 23 and limited post 26 1 ends are arranged in the main board 21, and the other end stretches out the one side of main board 21, and an end of mode locker 24 is arranged in the main board 21, and the other end stretches out another opposite face of main board 21.The mold insert 23 of loosing core is fixed in the main board 21 by pipe nail 25.
Under the matched moulds state, main board 21 be arranged in the front mold base 40 and the top concordant with it, mode locker 24 is inserted in the water gap plate 30, elastic force colloid 22 is inserted in the front mold base 40, the mold insert 23 of loosing core passes front mould beautiful 50 and props up goods 80.Be provided with caging bolt 90 between top board 90 and the water gap plate 10.Goods 80 take shape between front mould beautiful 50 and the rear mold jade 60, and thick mould jade is arranged in the rear mold base 70.
During die sinking, core-pulling mechanism mainly is when the water gap plate die sinking, and mechanism is because finishing the retraction action with water gap plate 10 die sinkings together under the elastic force effect of the traction that is subjected to mode locker 24 and elastic force colloid 22.Specifically such as Fig. 3-shown in Figure 6, mould is when die sinking, it at first is the first die sinking order, the acting in conjunction that water gap plate 10 drives mode lockers 24 and elastic force colloid 22 has bounced back core-pulling mechanism, and (S is the stroke of limited post 26 in main board 21 for the distance of S, in order to reduce the uncertain factor in the folding mold process, S is preferably between the 1.0-2.0mm), finished the first die sinking order.The not action of three-part pattern order this moment, namely when core-pulling mechanism bounces back, the front and back mould is fiting, namely realized the preferential demoulding at goods 80 demouldings difficulty position, in the ensuing continuation die sinking action, under the effect of caging bolt 90, in succession finished the action of the second die sinking order and three-part pattern order; The demoulding action that is the front mould glue position of product has realized separately finishing in the die sinking action of the first die sinking order and three-part pattern order respectively.In the matched moulds process, front mold core-pulling mechanism directly pushes back original position by water gap plate.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, make concrete change or change and all belong to protection domain of the present utility model.
