Description

The diel automatic retreating materials mechanism

Technical field

The utility model relates to the Stamping Die Technology field, especially relates to a kind of diel automatic retreating materials mechanism.

Background technology

Automobile panel utilizes in the mould punching production process, and the large or high stamped part of drawing depth for product profile complexity, profile drop product usually can occur and be adsorbed on the interior phenomenon of die, causes the pickup difficulty.For ease of pickup, increase the liftout core at mould, this mode can increase die space structure and complexity, additionally increases pressure source, and the requirement of press is also uprised, and increases the mould development cost.Or also can prevent to a certain extent getting stuck in the mode that mould arranges steam vent, but have little effect, use less.

As use the artificial pressure of machinery discharging, and will certainly cause damage to product, cause deformation of products, affect the stamping parts postorder and be shaped; Simultaneously, also can increase the punching production cycle, thereby reduce production efficiency, affect the mould result of use, enterprise's production competitiveness is reduced.

Unloading mechanism commonly used is for playing ejector pin at present, and as shown in Figure 3, structure and operation principle are as follows: push rod 5 links together by spring 3 threes with pilum 6, and whole mechanism is arranged on the die body 2, and the upper surface of pilum 6 can be a little less than the die profile.In the mould open mode, spring is in nature upholds, and push rod stretches out the die profile; When mold work, the push rod pressurized moves in pilum, and spring is initially located in compressive state; After the mould closure, the top of push rod contacts with plate, and concordant with the die profile; After press work finished, along with mould is slowly opened, spring began to release energy, and drove push rod and outwards moved, and push rod and then the plate that will be stuck in the die outwards promote, thereby realized automatic material returning.

This kind mechanism is in the blind hole that is directly installed on the die profile, and for reducing that the diel profile is damaged, the blind hole setting is less, the size of push rod is restricted naturally, the material returned power that spring can provide also can be restricted, and material returned effect is limited, can not guarantee material returned reliability.

The utility model content

Not enough for prior art, technical problem to be solved in the utility model provides a kind of diel automatic retreating materials mechanism, and it reduces the damage of die face is increased simultaneously the material returned power of spring, improves the reliability of automatic material returning.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of diel automatic retreating materials mechanism, this unloading mechanism comprises movable ejector beam and spring, also comprise briquetting, described movable ejector beam one end be directly arranged in the intrinsic through hole of die after spring one end is connected, the through hole setting of the corresponding die body of described briquetting, the described spring other end is connected with briquetting.

The intrinsic through hole of described die is stepped hole, and the aperture in the hole of close die body profile is less than the aperture in the hole of close briquetting in the stepped hole; The end of the described movable ejector beam that is connected with spring is the boss structure of adaptive stepped hole.

The outer face that described movable ejector beam is used for liftout is the curved surface consistent with die body profile.

Described briquetting is dismountable to be located on the die body.

The utility model compared with prior art has the following advantages:

1, movable ejector beam is directly installed in the intrinsic through hole of die, and is easy to process, directly utilizes the intrinsic through-hole guides of die, simple in structure;

2, the bottom uses briquetting to fix, and can take apart at any time, is convenient to the part replacement adjustment, forms different size for selecting;

3, through hole is stepped hole, and installation activity ejector beam can reduce the damage to die face in the pore of stepped hole; Settle spring in the gross porosity of stepped hole, the aperture can be determined according to the specification of spring, can select according to the actual requirements the spring of appropriate size, increase pusher power, make the usage quantity that can reduce unloading mechanism in a whole set of mould, further reduce the damage to die face, improve the product stamping quality;

4, the processing cost is low, has reduced the mould development manufacturing expense.

Description of drawings

The below briefly explains the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:

Fig. 1 is that the utility model unloading mechanism spring is in the release conditions schematic diagram.

Fig. 2 is that the utility model unloading mechanism spring is in the compressive state schematic diagram.

Fig. 3 is existing unloading mechanism organigram.

Among the figure: 1. movable ejector beam, 2. die body, 3. spring, 4. briquetting, 5. push rod, 6. pilum.

The specific embodiment

The below contrasts accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of diel automatic retreating materials mechanism, this unloading mechanism are located at and are used for ejecting on the die body 2 being stuck in the intrinsic plate of die, reach reliable automatic material returning purpose.

This unloading mechanism comprises movable ejector beam 1, spring 3, briquetting 4, and movable ejector beam 1 and spring 3 are located at die body 2 inside, and briquetting 4 is located at die body 2 outsides; Wherein, in the movable ejector beam 1 one ends through hole interior with being directly arranged in die body 2 after spring 3 one ends are connected, the intrinsic through hole of die is stepped hole, the aperture in the hole of close die body profile is less than the aperture in the hole of close briquetting in the stepped hole, the end of the movable ejector beam that is connected with spring is the boss structure of adaptive stepped hole, be in the less hole, movable ejector beam 1 aperture that is located at stepped hole, spring 3 is located in the larger hole, the aperture of stepped hole; The through hole setting of the corresponding die body of briquetting, the spring other end is connected with briquetting.

Movable ejector beam 1 is arranged in the pore of stepped hole according to the liftout stroke of actual needs, will exceed the die profile on the length; The setting of the intrinsic through hole of die is easy to process and the assembling of total, also be convenient to the replacing of parts, and movable ejector beam can also lead with this directly.
