Abstract
The utility model discloses a die for an inner sliding block. The die at least comprises a female die plate and a male die plate which are vertically matched, wherein a female die core and a male die core are respectively arranged in the female die plate and the male die plate, and the inner sliding block is arranged in the male die core. A lug close to the direction of the male die core from top to bottom and with a certain gradient is arranged on the inner sliding block, a gradient bunch block with the gradient consistent with that of the lug is apart from the lug by the bevel side surface of the gradient bunch block, and one side surface of the male die core is locked in the female die plate through a screw piece in a contact way. The gradient bunch block and a positioning device are used to push the inner sliding block and control the positioning of the inner sliding block, so that the fluke structure of the plastic product can be stripped, the die structure is simple, the process is simple, and the die cost can be greatly reduced.
Description
Technical field
The utility model relates to a kind of processing fixture, particularly a kind of inner slide mould with overhead kick type product drawing-out mechanism.
Background technology
When utilizing mould-forming process to make plastic product, need to utilize the mould structure of making in advance, and the plastics of fusion are injected among the mould to reach the purpose of shaped article by injection machine.
At present, the slide block of mould is mainly used in the subsidiary products moulding, and overhead kick is arranged on product, and overhead kick wherein partly needs the oblique tip to withdraw from, if the exit axis stroke is not enough, withdraws from this oblique tip formula structure, can bump against other shapes on the product; Therefore, higher and inwall has the overhead kick constructed products for sidewall, can't utilize oblique tip mechanism to break away from overhead kick, and adopt the mould of slide block structure to process more.
As shown in Figure 1, for having the cutaway view of slide block mould now.Wherein, form cavity 2 between the mother module core 11 of this mould and the male model benevolence 21, because of two lateral bucklings of the plastic cement products of moulding in this cavity 2 and have the overhead kick structure, in slide block 22, be provided with from top to bottom to the approaching through hole with constant slope 221 of described male model benevolence 21 directions, be provided with the pulling block 12 consistent in the mother module core 1 with through hole 221 gradients, described slide block is connected with spring away from an end of described male model benevolence, and the block of establishing in the other end of this spring and the male model plate 2 23 links to each other.
When hot glue solution being injected in the cavity 2 and after cooling off, described caster 1 drives described pulling block 12 when moving away from the direction of described male model plate 2, this pulling block 12 can promote described slide block 22 and move to close described male model benevolence 21 directions, thereby makes the overhead kick structure of product be separated with described slide block 22.
Above-mentioned slide block mould is to utilize the active force of pulling block to make slide block withdraw from the overhead kick stroke, yet the mechanism of this slide block mould is very complicated, its structure more complicated, and processing cost is higher, and follow-up maintenance is comparatively complicated.
The utility model content
Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of overhead structure of and product and the inner slide mould that other shape and structures can not produce interference are provided.
The technical solution of the utility model is: a kind of inner slide mould, this mould comprises the caster and the male model plate of upper and lower cooperation at least, wherein, be respectively arranged with mother module core and male model benevolence in described caster and the described male model plate, and also be provided with inner slide in the male model benevolence; This inner slide is provided with from top to bottom to the approaching projection with constant slope of described male model benevolence direction, and the gradient bundle piece consistent with described projection gradient is locked in the described caster by screw piece in its prism and the described projection contacted mode in a side away from described male model benevolence.
More excellent, in the described inner slide part that contacts with described male model benevolence positioner is installed.
More excellent, described positioner comprises: positioning ball is locked in the corresponding position of described male model benevolence; Recessed, be opened in the corresponding position of described inner slide.
Compared with prior art, the utility model adopts gradient bundle piece and positioner that inner slide is promoted and positioning control, thereby makes that the overhead kick structure of plastic cement products is withdrawed from, and this mould structure is simple, and manufacturing procedure is simple, can reduce the cost of mould greatly.

The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
See also shown in Figure 2, a kind of inner slide mould, this mould comprises at least, the caster 4 of following cooperation and male model plate 5, wherein, be respectively arranged with mother module core 41 and male model benevolence 51 in described caster 4 and the described male model plate 5, and also be provided with inner slide 52 in the male model benevolence 51, this inner slide 52 is provided with from top to bottom to the approaching projection with constant slope 521 of described male model benevolence 51 directions, and the gradient bundle piece 42 consistent with described projection 521 gradients is locked in the described caster 4 by screw piece 6 in its prism and the described projection 521 contacted mode in a side away from described male model benevolence 51; Described inner slide 52 part that contacts with described male model benevolence 51 also is equipped with positioner 7, and this positioner 7 comprises: positioning ball 71 is locked in the corresponding position of described male model benevolence 51; Recessed 72, be opened in the corresponding position of described inner slide 52.
Please consult Fig. 3 and shown in Figure 4 simultaneously, the part-structure schematic diagram during for the utility model die opening state.In hot glue solution is injected into cavity 3 and after cooling, the moment of this mould die sinking, described gradient bundle piece 42 along with described caster 4 to moving away from described male model plate 5 directions, this gradient bundle piece 42 can promote described projection 521, thereby make described inner slide 52 to moving, the overhead kick structure of forming plastic cement product and described inner slide 52 are broken away near described male model plate 5 directions; Along with described caster 4 continues to moving away from described male model plate 5 directions, the forming plastic cement product can be by withdrawing from the caster, thereby can successfully be removed.
Wherein, described positioner 7 can be controlled the relative position of described inner slide 52 and described male model benevolence 51, and itself and described mother module core 41 are formed and the corresponding to cavitys of processing plastic shape of product.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by claim of the present utility model.
