Description

Auxiliary die positioning structure

Technical Field

The utility model relates to a mould field, specific theory has related to an auxiliary mold positioning structure.

Background

The die refers to various dies and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. At present, front and rear mold cores of most molds in the market are precisely positioned by means of guide columns or guide sleeves of the molds. However, when the die is large or the temperature of the die is high, the die steel has thermal expansion, and the front die and the rear die have certain temperature difference in the production process, so that deformation may occur to reduce the positioning accuracy of the die guide pillar, thereby increasing the reject ratio of products, increasing the maintenance cost of the die and reducing the service life of the die.

In order to solve the above problems, people are always seeking an ideal technical solution.

Based on the above, a second elastic member is provided between the rear cavity plate and the upper end of the screw.

Based on the above, the second elastic member is an elastic gasket.

Based on the above, the first elastic member is an elastic gasket.

Based on the above, the front mold core, the front mold cavity plate, the rear mold core and the rear mold base plate are sequentially arranged from top to bottom and are correspondingly provided with positioning holes, positioning pins are installed in the positioning holes, screw through holes are formed in the positioning pins, and screws are arranged in the screw through holes.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides an auxiliary mold positioning structure, this auxiliary mold positioning structure make after the drawing of patterns, the back mould benevolence has certain elasticity space, can avoid the inside location precision that produces deformation and make the mould of mould to a certain extent to improve the product percent of pass, reduce mould maintenance cost, extension mould life.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a rear cavity plate; 2. a second positioning pin; 3. a front cavity plate; 4. a first screw; 5. a second elastic member; 6. a first elastic member; 7. a first positioning pin; 8. a fixing plate; 9. a front mold core; 10. a rear mold core; 11. a rear mold backing plate; 12. a second screw.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1, an auxiliary mold positioning structure, a mold includes a front mold core 9, a front mold cavity plate 3, a rear mold cavity plate 1, a rear mold core 10, a rear mold backing plate 11 and a fixing plate 8, the fixing plate 8 is located at a side portion of the rear mold core 10, a gap is left between the rear mold cavity plate 1 and the fixing plate 8, and a first elastic element 6 is disposed in the gap; the rear die cavity plate 1, the first elastic piece 6 and the fixing plate 8 are correspondingly provided with positioning holes, positioning pins are arranged in the positioning holes, screw through holes are formed in the first positioning pins 7 and are provided with first screws 4, and threaded holes are formed in the lower portions of the positioning holes of the fixing plate 8 and correspond to the lower ends of the first screws 4. Specifically, the connection and installation modes of the mold including a front mold core 9, a front mold cavity plate 3, a rear mold cavity plate 1, a rear mold core 10, a rear mold backing plate 11, a fixing plate 8 and the like are all according to a conventional mold structure, and the mold positioning can adopt a conventional guide pillar or guide sleeve structure; the first elastic element can adopt a conventional elastic structure as long as the mold core can have a certain elastic space after the mold is opened.

The rear die cavity plate and the fixing plate are connected through the first screw and the first elastic piece, and the first elastic piece enables the rear die cavity plate to have a certain floating space on the fixing plate, and a gap is reserved between the first positioning pin and the positioning hole of the rear die cavity plate, so that the rear die cavity plate floats on the fixing plate within a small range.

After this supplementary mould location structure made the drawing of patterns, the back mould benevolence had certain elasticity space, can avoid the inside deformation that produces of mould to make the positioning accuracy of mould descend to a certain extent to improve the product percent of pass, reduce mould maintenance cost, extension mould life.

In one embodiment, a second elastic member 5 is disposed between the rear cavity plate 1 and the upper end of the first screw 4; specifically, the second elastic member and the first elastic member may have the same or different structures.

In one embodiment, the second elastic member 5 is an elastic pad, and in other embodiments, other elastic structures may be adopted as needed.

In one embodiment, the first elastic member 6 is an elastic pad, and in other embodiments, other elastic structures may be adopted as needed.

In one embodiment, the front mold core 9, the front mold cavity plate 3, the rear mold cavity plate 1, the rear mold core 10, and the rear mold backing plate 11 are sequentially disposed from top to bottom and are correspondingly provided with positioning holes, the second positioning pins 2 are installed in the positioning holes, screw through holes are formed in the second positioning pins 2, and second screws 12 are disposed in the screw through holes. Preferably, the lower section of the second positioning pin is trapezoidal. In the use, carry out accurate location to front mould benevolence, front mould cavity board, back mould cavity board through the second locating pin, satisfy the precision demand.

The above embodiments may be combined with each other.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
