Abstract
The utility model discloses a sand clamping structure for improving a casting deviation box. The utility model adopts the following technical scheme: the sand clamping structure for improving the casting deviation box comprises an upper sand box and a lower sand box, which is characterized in that: an off-centering lock box hook is arranged between an upper sand box shaft and a lower sand box shaft; the upper end and the lower end of the off-centering lock box hook respectively hook up the upper sand box shaft and the lower sand box shaft. Due to the adoption of Phi 50mm box shafts of the upper sand box and the lower sand box and the clamping of the off-centering lock box hook, the turning moment is prevented, so as to improve the deviation amount. The deviation of the casting is fundamentally efficiently improved.
Description
Technical field
The utility model relates to the mould structure field of moulding machine, more particularly, relates to improve the wrong sand mold clamping structure of case partially of foundry goods.
Background technology
All there is in various degree wrong deviator in the design of the mould structure of homemade Z146, Z148 moulding machine in links such as mould installation, moulding, mould assembling, clampings usually, because the mutual superposition of the dimensional discrepancy of each link, usually cause the wrong deviator of part foundry goods to exceed the product engineering standard-required and scrap, the requirement of the looking different foundry goods scrappage of foundry goods does not sometimes wait up to 30-60%.The traditional clamping mode of upper and lower sandbox is the pin-and-hole by upper and lower sandbox case ear ∮ 26 ㎜, clamps with ∮ 24 ㎜ holding pins and drift hammering form diagonal angle when closing pin inserts state; But because the gap between the pin-and-hole produces cyclovergence under the effect of hammering moment, cause foundry goods partially wrong, cause mould shift.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of wrong sand mold clamping structure of case partially of foundry goods that improves is provided.
The utility model improves the wrong sand mold clamping structure of case partially of foundry goods, be achieved by following technical proposals, comprise cope and drag box, it is characterized in that, the case between centers of described cope and drag box is provided with eccentric lock case hook, and described eccentric lock case hook top and bottom are caught on cope case axle and drag box case axle respectively.
The utility model adopts eccentric lock case hook to clamp by upper and lower sandbox ∮ 50 ㎜ case axles, improves wrong deviator thereby avoid producing turning moment, and foundry goods produces wrong inclined to one side phenomenon and fundamentally obtained effective improvement.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the case between centers of described cope 1 and drag box 2 is provided with eccentric lock case hook 3, and described eccentric lock case hook top and bottom are caught on cope case axle 4 and drag box case axle 5 respectively.
The utility model adopts eccentric lock case hook to clamp by upper and lower sandbox ∮ 50 ㎜ case axles, improves wrong deviator thereby avoid producing turning moment, and foundry goods produces wrong inclined to one side phenomenon and fundamentally obtained effective improvement.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
Claims (1)
1. one kind is improved the wrong sand mold clamping structure of case partially of foundry goods, comprise cope and drag box, it is characterized in that the case between centers of described cope and drag box is provided with eccentric lock case hook, described eccentric lock case hook top and bottom are caught on cope case axle and drag box case axle respectively.
