Abstract

The utility model discloses an improved wrench die structure and relates to a wrench die. The improved wrench die structure includes die feet, a B plate, an A plate, an oblique guide pillar, a front die core, a back die core, a feed pipe, a spreader, foundations and stop blocks; the B plate is arranged on the die feet; the A plate is disposed on the B plate; the oblique guide pillar is inserted in the A plate; the front die core is disposed in the A plate; the back die core is disposed in the B plate; the feed pipe is disposed on the A plate and is communicated with the back die core; the spreader is fixed on the back die core and is inserted into the feed pipe on the front die core; the stop blocks are fixed on the B plate; the foundations are arranged on two ends of the A plate and one ends of the foundations are disposed inside the stop blocks; divider mouths of a running channel are uniformly distributed on the back die core. The die has a stable structure and decreases water marks and cold marks in die casting; a qualified rate of die-cast products is greatly increased; a product polishing quality is enhanced after employing the new structure; a qualified rate of the polished products is greatly increased; therefore, a product qualified rate is increased and a production cost is decreased.

Description

A kind of spanner mould structure of improvement

Technical field

The utility model relates to mould, relates in particular to the mould of spanner.

Background technology

Like Fig. 1 and a kind of spanner shown in Figure 2, this series products belongs to the zinc alloy diecasting product that complicacy and surface quality are had relatively high expectations, this series products his-and-hers watches face require quality very high, scuffing must not be arranged, damage, water wave and cold line etc.; Originally this series products compression mod adopts conventional dc feeding manner, and the surface generally appears in the product of die casting has water wave, cold line, and scrappage is high, and because slide block and mould-dividing mode are improper, cause the polishing of a lot of positions less than, scrappage is high after the surface treatment.

The utility model content

The utility model is not enough to prior art, aims to provide a kind of improvement of spanner mould structure, through developing new mould structure and die sinking structure, solves product water wave, cold line, polishing is not in place and cause the high problem of scrappage.

The utility model is realized through following technical scheme: a kind of spanner mould structure of improvement comprises mould pin, B plate, A plate, Angle Pin, preceding die, back die, material pipe, divides flow cone, produces base and limited block, and the B plate is arranged on the mould pin, and the A plate is arranged on the B plate; Angle Pin is plugged on the A plate; Preceding die is arranged in the A plate, and back die is arranged in the B plate, and the material pipe is arranged on the A plate and with the back die and is communicated with; The branch flow cone is fixed in the material pipe of back die and the preceding die of plant; Limited block is fixed on the B plate, produces a basic end that is arranged on A plate two ends and product base and is arranged on limited block inside, and the diffluence pass of running channel is uniformly distributed on the die of back.

Do further to set forth in the face of above technical scheme down:

The utility model also comprises first core-pulling mechanism, second core-pulling mechanism and the 3rd core-pulling mechanism, and first core-pulling mechanism is fixed preceding benevolence mould and back benevolence mould, and second core-pulling mechanism is fixed A plate and preceding benevolence mould, and the 3rd core-pulling mechanism is fixed back benevolence mould and B plate.

The beneficial effect of the utility model is: one of which, the utility model adopt common die version, optimize runner and feeding manner again, and employing order feed solutions changes slide block and mould-dividing mode, and its die parting line all is arranged on the face that can polish; After two, die casting is accomplished under the mould matched moulds state; First core-pulling mechanism is fixed preceding benevolence mould and back benevolence mould; Second core-pulling mechanism is fixed A plate and preceding benevolence mould; The 3rd core-pulling mechanism is fixed back benevolence mould and B plate, is carried out to take out first core-pulling mechanism, second core-pulling mechanism and the 3rd core-pulling mechanism by Angle Pin during the mould die sinking and realizes die sinking, then taking-up product after back mould thimble ejects; Accomplish the following process of product again through modes such as polishing, surface treatments; Three, the Stability Analysis of Structures of the utility model mould; Can improve water wave, cold line phenomenon during die casting; The die-cast product qualification rate improves greatly, and adopts that the quality of product polishing has also improved behind the new construction, and the polishing product percent of pass also improves greatly; So promptly improve the qualification rate of product, reduced production cost.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Shown in Fig. 1-5, the B plate 2 of the utility model is arranged on the mould pin 1, and A plate 3 is arranged on the B plate 2; Angle Pin 4 is plugged on the A plate 3; Preceding die 12 is installed in the A plate 3, and back die 13 is installed in the B plate 2, and material pipe 5 is arranged on the A plate 3 and with back die 13 and is communicated with; Branch flow cone 6 is fixed in back die 13 and is plugged in the material pipe 5 of preceding die 12; Limited block 8 is fixed on the B plate 2, and the end that product base 7 is installed in A plate 3 two ends and product base 7 is arranged on limited block 8 inside, and the diffluence pass of running channel is uniformly distributed on the die 13 of back.With reference to shown in Figure 4, first core-pulling mechanism 9 is fixing with back benevolence mould 13 with preceding benevolence mould 12, and second core-pulling mechanism 10 is fixing with A plate 3 and preceding benevolence mould 12, and the 3rd core-pulling mechanism 11 is fixed back benevolence mould 13 with B plate 2.

The utility model is under tool matched moulds state; First core-pulling mechanism 9 is fixing with back benevolence mould 13 with preceding benevolence mould 12; Second core-pulling mechanism 10 is fixed A plate 3 and preceding benevolence mould 12; The 3rd core-pulling mechanism 11 is will back benevolence mould 13 fixing with B plate 2, is carried out to take out first core-pulling mechanism 9, second core-pulling mechanism 10 and the 3rd core-pulling mechanism 11 by Angle Pin 4 during the mould die sinking and realizes die sinkings, and the mould thimble ejects back taking-up product in the back then; Accomplish the following process of product again through modes such as polishing, surface treatments.

According to the announcement and the instruction of above-mentioned specification, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to is in the protection domain of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
