Description

Technical Field

[0001] The utility model relates to the field of forming molds, in particular to an aluminum cover plate anti-dark crack forming mold. Background Technique

[0002] Cast aluminum is a process method in which pure aluminum or aluminum alloy ingots are prepared according to standard component ratios, then artificially heated to turn them into aluminum alloy liquid or molten state, and then the aluminum liquid or molten aluminum alloy is poured into the cavity through a professional mold or corresponding process, and cooled to form the required shape of aluminum parts.

[0003] Chinese Patent No. CN202022508360.6 discloses an anti-dark crack cast aluminum mold, which is characterized by including a lower mold, a vibration mechanism, a chassis, a slider, and a slide rail. The left and right sides of the bottom of the lower mold are welded with sliders. There are slide rails at the bottoms of the two sliders. The slide rails are provided with chutes, and the sliders are used in cooperation with the chutes. A vibration mechanism is arranged on the left side of the lower mold; the vibration mechanism is composed of a chassis, a cam, a telescopic rod, a spring, a right spring pad, and a left spring pad. A chassis is arranged on the left side of the lower mold. The left side wall of the lower mold is respectively installed with a right spring pad and a right side backing plate through bolts, and the right side backing plate is installed on the left side wall of the spring pad.

[0004] As can be seen from the above, by setting the left spring pad and the right spring pad, when the spring and the cam work, since the acting force generated by the spring will not directly act on the lower mold and the chassis, the left spring pad and the right spring pad play a protective role, thus avoiding scratches on the lower mold and the chassis and effectively improving the service life of the lower mold and the chassis. However, this case still has the following deficiencies: when forming and casting the aluminum cover plate, when the two molds are not fixed firmly and shake, it will not only directly affect the accuracy and quality of the forming process, but may also cause damage to the mold.

[0005] Therefore, an aluminum cover plate anti-dark crack forming mold is proposed for the above problems. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem of affecting the accuracy and quality of the forming process, the utility model proposes an aluminum cover plate anti-dark crack forming mold.

[0007] The technical solution adopted by the utility model to solve its technical problems is: an aluminum cover plate anti-dark crack forming mold described in the utility model includes a base and a fixing component; a pressing plate is installed on the fixing component, a flow channel is fixedly installed on the top of the pressing plate, and several limiting rods are fixedly installed on the bottom of the pressing plate. One ends of the several limiting rods respectively penetrate and are movably installed on an upper mold, and one ends of the several limiting rods respectively penetrate and are movably installed on a lower mold.

[0008] Preferably, a support base is installed on the base, and a lower mold is fixedly installed on the top of the support base.

[0009] Preferably, an upper mold is placed on the top of the lower mold, and two sliding plates are fixedly installed on the top of the upper mold.

[0010] Preferably, fixing seats are respectively fixedly installed on the tops of the two sliding plates, and sliding blocks are respectively movably installed on the tops of the two sliding plates.

[0011] Preferably, two threaded shafts are fixedly installed on one side of the fixing seat. The two threaded shafts penetrate through and are movably installed with the sliding blocks, and the two threaded shafts are respectively threadedly connected with nuts.

[0012] Preferably, two fixing rods are fixedly installed on the bottom of the pressing plate. One ends of the two fixing rods respectively penetrate through and are movably installed with the sliding blocks.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the structural design of the fixing component of the present utility model, when the pressing plate moves, the fixing rod drives the sliding block in a linkage manner, and the sliding block slides on the sliding plate, causing the sliding block to displace to one side. The nut is in threaded fit with the threaded shaft, converting the rotational movement of the nut into its linear movement, so that the nut limits one side of the sliding block. At this time, the top of the lower mold and the upper mold are limited and firmly fixed, realizing the function of limit fixation, solving the problem of affecting the precision and quality of the forming process, and improving the adaptability in use.
