Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a lead alloy plate forming mold with a leveling function. Background Technology

[0002] Lead alloy sheet is an alloy sheet composed of lead and other metallic elements. It has high density and good corrosion resistance and is often used in applications such as radiation protection, sound insulation, and acid and alkali resistance. In the production and processing of lead alloy sheet, in order to ensure the uniformity of the processed shape and size of the lead alloy sheet, guarantee product quality, improve production efficiency, and reduce costs, lead alloy sheet forming molds are required to form and process the lead alloy sheet.

[0003] According to the heat leveling mold disclosed in patent number CN201721286694.5, by setting a first rectangular groove and a second rectangular groove and a protruding rectangular block, the contact area between the load-bearing part and the counterweight part is effectively reduced, thereby improving the flatness of the contact surface and improving the flatness of the thin plate to be leveled.

[0004] In actual operation, the mold can improve the flatness of the contact molding surface by setting concave and convex structures, which can play a leveling role. However, during the leveling process of the upper and lower molds closing, the hard contact between the upper and lower molds can easily cause certain impact damage to the mold, which is a shortcoming and makes it inconvenient to perform buffering and leveling inside the mold.

[0005] Now, a novel lead alloy plate forming mold with a leveling function is proposed to address the above-mentioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a lead alloy plate forming mold with a leveling function to solve the problem mentioned in the background art of inconvenience in buffering and leveling the inside of the mold.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a lead alloy plate forming mold with a leveling function, comprising a connecting seat, a lower pressing mold provided at the top of the connecting seat, and an upper pressing mold provided at the top of the lower pressing mold, guide columns being vertically fixed on both sides of the bottom of the upper pressing mold, and a leveling structure for leveling the mold being provided between the upper pressing mold and the lower pressing mold.

[0008] The leveling structure includes a leveling plate, guide rods, buffer spring one, buffer spring two, sliding sleeves, and guide holes. A leveling plate is provided between the lower and upper pressure molds, and sliding sleeves are fixed to both sides of the top of the leveling plate. Buffer spring one is fixed to both sides of the top of the leveling plate, and buffer spring two is fixed to both sides of the top of the leveling plate. Guide rods are fixed to the four corners of the top of the leveling plate, and guide holes are opened inside the four corners of the bottom of the upper pressure mold.

[0009] As a further technical solution of this utility model, the sliding sleeve penetrates the interior of the calibration plate, and the guide post penetrates the interior of the sliding sleeve.

[0010] As a further technical solution of this utility model, the top ends of the first buffer spring and the second buffer spring are fixedly connected to the bottom end of the upper pressure mold, and the second buffer spring is provided in three sets at equal intervals at both ends of the top of the calibration plate.

[0011] As a further technical solution of this utility model, through holes are respectively opened on both sides of the bottom end of the lower die, the bottom end of the guide post penetrates the interior of the through holes, mounting grooves are respectively provided on both sides of the top end of the lower die, a corrugated sleeve is sleeved on the outer side of the guide post, and a fixing ring is fixed at the bottom end of the corrugated sleeve. Inner holes are respectively opened on both sides and both ends of the top of the fixing ring, and mounting bolts are provided inside the inner holes. Threaded holes are respectively opened on both sides and both ends of the bottom of the mounting groove, and the guide post penetrates the interior of the fixing ring.

[0012] As a further technical solution of this utility model, the bottom end of the mounting bolt penetrates the interior of the inner hole and is threadedly connected to the threaded hole.

[0013] As a further technical solution of this utility model, a fixing cover is provided at the bottom of the upper mold, and an insertion hole is opened in the interior of the four corners of the top of the fixing cover, and a fixing bolt is provided in the interior of the insertion hole. A screw hole is opened in the interior of the four corners of the top of the upper mold.

[0014] As a further technical solution of this utility model, the bottom end of the fixing bolt passes through the interior of the insertion hole and is threadedly connected to the screw hole.

[0015] As a further technical solution of this utility model, the bottom end of the guide post is fixedly connected to the top end of the connecting seat, and a base plate is fixed to the bottom end of the connecting seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the lead alloy plate forming mold with leveling function not only facilitates the buffering and leveling of the mold interior, facilitates dust prevention on the outside of the internal guide components of the forming mold, but also facilitates auxiliary protection on the outside of the forming mold.

[0017] By using a forming mold with a connecting seat, lower die, leveling plate, guide rod, buffer spring one, upper die, buffer spring two, guide post, sliding sleeve, and guide hole, a leveling plate is set between the lower die and the upper die during the forming process of lead alloy plate.

At the same time, buffer spring two is set on both sides and both ends of the top of the leveling plate, which can play a role in buffering and leveling. The leveling process can reduce the deformation that occurs during the pressure forming process and assist in leveling the stamping surface of the die plate. Through the downward tension of buffer spring one and buffer spring two, the die plate is pressed. During the demolding process, it can greatly avoid the deformation of the plate surface caused by the stamping pin pulling the plate surface when the upper and lower dies are separated in traditional stamping, which causes secondary shaping labor costs. At the same time, the elasticity of buffer spring one and buffer spring two can help the upper and lower dies separate.

[0018] The forming mold is equipped with guide posts, corrugated sleeves, mounting grooves, retaining rings, threaded holes, mounting bolts, and inner holes. When the mold is in use, a corrugated sleeve is set on the outside of the inner guide post. The corrugated sleeve can be used to provide an auxiliary outer cover to seal the outside of the guide post, reducing the adhesion of dust on the outside of the guide post and preventing external obstruction during the guiding process.

[0019] With an upper mold, a fixing cover, fixing bolts, insertion holes, and screw holes, the molding die is installed and used with a fixing cover fixed at the top of the upper mold using fixing bolts. The fixing cover can protect the outside of the molding die assembly from impact and reduce structural damage to the outside of the molding die. Attached Figure Description

[0030] Specifically, such as Figures 1-3As shown, a leveling plate 3 is provided between the lower die 2 and the upper die 6. During the pressing process between the lower die 2 and the upper die 6, the leveling plate 3 can be used to assist in leveling the contact surface. At the same time, buffer springs 7 are provided on both sides and both ends of the top of the leveling plate 3, which can play a role in buffering and leveling, reducing collision damage. The leveling process can reduce the deformation that occurs during the pressure forming process and assist in leveling the stamping surface of the die plate.

When the stamping pin pulls on the plate surface, causing deformation, it results in the labor cost of secondary reshaping. At the same time, the elasticity of buffer spring 5 and buffer spring 7 can help the upper and lower dies separate. When the forming die is in use, a corrugated sleeve 11 is provided on the outside of the internal guide post 8. The corrugated sleeve 11 can be used to provide auxiliary outer cover sealing and dust prevention for the outside of the guide post 8.
