Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a small slider forming mechanism. Background Technology

[0002] Small parts such as die-cast camera brackets are difficult to handle after molding due to their small size. Also, the small size of the products and the small gap in the mold positioning cause the mold to jam after punching. In addition, the small size of each product makes it easy to deform the product when handled manually. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model designs a small slider forming mechanism.

A lower template is fixedly installed on the lower mold base. A lower pressure plate is fixedly installed at the bottom of the upper mold base. The upper template is installed at the bottom of the lower pressure plate via a guide shaft and a spring. The upper template moves along the guide shaft. A mold core is provided between the upper and lower mold bases. The mold core includes an upper mold core and a lower mold core. The upper mold core is fixed at the bottom of the upper mold base, and the lower mold core is correspondingly fixed on the lower mold base. Punches are respectively opened on the upper mold base, the lower mold base, the upper mold core, and the lower mold core. A punch is fixedly installed on the lower pressure plate, and the punch cooperates with the punch. A product placement position is provided on the lower mold core. Multiple sliding grooves are respectively provided on the lower mold core at the outer edge of the product placement position. A slider is slidably connected in the sliding groove. A product positioning contact surface is provided at the upper end of the slider. The product positioning contact surface is a tapered inclined surface. Elastic element mounting holes are correspondingly provided in the sliding grooves of the slider and the lower mold core. Elastic elements are placed in the elastic element mounting holes.

[0005] Preferably, the elastic element is an elastic silicone sheet.

[0006] Preferably, multiple mold cores are provided between the upper and lower mold templates.

[0007] Preferably, a ring of downward pressing bosses is provided on the upper mold core corresponding to the position of the slider.

[0008] Preferably, the lower mold base is provided with external limiting posts on both sides to limit and prevent overpressure.

[0009] Preferably, the lower template is provided with inner limiting posts on both sides to limit and prevent overpressure.

[0010] Preferably, the lower die holder has a chip discharge port corresponding to the punch hole, which facilitates the discharge of continuous product material.

[0011] The beneficial effects of this utility model are: This utility model designs a small slider forming mechanism, changes the positioning form, and positions the slider at a tight distance by moving the slider. After punching, the slider bounces up through the elastic element, increasing the gap between the slider and the product, which can be quickly picked up and put away, improving product yield and production efficiency.

Detailed Implementation

[0013] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figure 1 As shown, a small slider forming mechanism includes an upper mold base 2 and a lower mold base 1. A lower template 3 is fixedly installed on the lower mold base, and a lower pressure plate 4 is fixedly installed at the bottom of the upper mold assembly. An upper template 5 is installed at the bottom of the lower pressure plate via a guide shaft and a spring. The upper template moves along the guide shaft. A mold core 8 is provided between the upper and lower templates. The mold core includes an upper mold core 9 and a lower mold core 10. The upper mold core is fixed at the bottom of the upper template, and the lower mold core is correspondingly fixed on the lower template. Punches 14 are respectively opened on the upper template, lower template, upper mold core, and lower mold core. Punches 11 are correspondingly fixedly installed on the lower pressure plate and cooperate with the punches. A product placement position 15 is provided on the lower mold core. Multiple sliding grooves are respectively provided on the lower mold core at the outer edge of the product placement position. A slider 12 is slidably connected in the sliding groove. A product positioning contact surface 17 is provided at the upper end of the slider. The product positioning contact surface is a conical inclined surface. Elastic element mounting holes 16 are correspondingly provided in the sliding grooves of the slider and the lower mold core. Elastic elements are placed in the elastic element mounting holes.

[0014] The elastic element is a flexible silicone sheet. A ring of downward-pressing bosses is provided on the upper mold core corresponding to the slider position. Outer limiting posts 6 are provided on both sides of the lower mold base. Inner limiting posts 7 are provided on both sides of the lower mold plate. Chip removal ports are provided on the lower mold base corresponding to the punch holes.

[0015] When using this small slider forming mechanism, the operator manually places product 13 into the product placement position of the lower die core. The upper die core descends via a punch press to press the product. The upper die core on the upper template contacts the lower die core first, and the lower pressing boss presses the slider, pushing the slider to slide and reduce the gap between the product and the slider to the design value, precisely positioning the product. After compaction, the punch press continues to press down, and the punch cuts off the product's connecting material, simultaneously punching the product to improve efficiency. After the product is punched, the upper die core moves upward and disengages from the slider. The slider bounces up through the elastic element, increasing the gap between the slider and the product. At this point, the product can be removed and placed. This method can improve product yield and production efficiency.

[0016] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
