Description
Technical field
The utility model relates to a kind of mould, specifically refers to a kind of plunger type mould making rubber part.
background technology
In motor production industry, often need to use rubber part miscellaneous, rubber running-on that the rubber seal such as sealed, line use etc.The mould structure used when making these rubber parts not only decides production efficiency, also decides the quality of part.For the rubber running-on 1 that the conventional line shown in accompanying drawing 1 uses, this rubber part is vertebra tubular, cylinder internal cavity forms through wires hole 2, barrel is provided with the upper flange of protrusion, 3 and lower flange 4, form draw-in groove 5 between upper lower flange, utilize this draw-in groove to be stuck in the body wall at line position by rubber running-on.When designing the making mould of this rubber part, one is that the alignment of requirement mould is high, and two is that requirement die assembly is simple, part takes out easily.
Summary of the invention
The purpose of this utility model provides a kind of mould making this rubber part for the rubber running-on class part used at present, and this mould adopts plunger type work, the technique effect that assembling is simple to reach, part easily takes out.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of plunger type mould making rubber part, comprise upper die and lower die and middle mould, it is characterized in that: also comprise packing ring, the surface of described counterdie is provided with middle mould seat pocket, be provided with vertical threading casement post at the center of counterdie, be provided with lower flange die cavity at the periphery of punching casement column bottom; Described middle mould edge is provided with the seam coordinated with middle mould seat pocket, packing ring seat pocket is provided with in middle mould bottom surface, middle mould surface is provided with extruding orifices, between upper extruding orifices and middle mould bottom surface, be provided with cavity, and the contour shape of described cavity is consistent with the contour shape on rubber part draw-in groove top; The compression leg coordinated with extruding orifices upper on middle mould is provided with bottom described patrix; Cavity in described punching casement post, middle mould, packing ring and patrix compression leg are coaxially arranged; When after patrix, middle mould, lower die combination, in the packing ring seat pocket of packing ring between middle mould and counterdie, threading casement post is through the cavity in packing ring and middle mould, and the space between threading casement post and middle die cavity body, packing ring and the lower flange die cavity on counterdie form rubber part die cavity jointly.
The beneficial effects of the utility model are, structure is simple, and cost is low, rational technology, production efficiency and practical efficiency higher.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 7, the plunger type mould of this making rubber part, comprises patrix 6, counterdie 7, middle mould 8, packing ring 9.
As shown in accompanying drawing 5 and accompanying drawing 6, the surface of counterdie 7 is provided with middle mould seat pocket 7-1, is provided with vertical threading casement post 7-2, is provided with lower flange die cavity 7-3 at the periphery of punching casement column bottom at the center of counterdie.
As shown in accompanying drawing 3 and accompanying drawing 4, middle mould 8 edge is provided with the seam 8-1 coordinated with middle mould seat pocket 7-1, packing ring seat pocket 8-2 is provided with in middle mould bottom surface, middle mould surface is provided with extruding orifices 8-3, between upper extruding orifices and middle mould bottom surface, be provided with cavity 8-4, the contour shape of described cavity 8-4 is consistent with the contour shape on the rubber part 1 draw-in groove top shown in accompanying drawing 1.
As shown in Figure 2, the compression leg 6-1 coordinated with extruding orifices upper on middle mould is provided with bottom patrix 6.
As shown in Figure 7, after the combination of patrix 6, counterdie 7, middle mould 8 and packing ring 9, cavity 8-4 in punching casement post 7-2, middle mould, packing ring 9 and patrix compression leg 6-1 are coaxially arranged, in the packing ring seat pocket 8-2 of packing ring 9 between middle mould and counterdie, threading casement post 7-2 is through the cavity 8-4 in packing ring 9 and middle mould, and the space between threading casement post 7-2 and middle die cavity body 8-4, packing ring 9 and the lower flange die cavity 7-3 on counterdie form rubber part die cavity 10 jointly.
This mold use operating process is:
(A) all parts are got out, patrix, middle mould, counterdie, packing ring.
(B) packing ring is placed in middle mould, then during counterdie is inserted in mould, counterdie and middle mould seam close
(C) rubber weighing up weight is placed in middle mould, then puts into patrix, patrix coordinates with middle mould seam, and patrix is stressed, runs downwards, in rubber press-in die cavity.
(D) after rubber part is shaping, suitable instrument is placed in patrix and middle die clearance, upwards exert oneself, take patrix away, die flip, suitable instrument is placed in counterdie and middle mould space, upwards exerts oneself, counterdie is exited, utilizes the elasticity of rubber part to be backed off by rubber part by packing ring.
