Description

Technical Field

[0001] This utility model belongs to the field of installation mold technology, specifically relating to a mold for quickly adjusting the closed height. Background Technology

[0002] In multi-station dies of hot forging presses for tooth blanks, an upsetting die is typically included. Depending on the actual working conditions, the closed height of the upsetting die needs frequent adjustment. Existing patent CN223288918U discloses an improved forging die, including a base and a top plate. The base is fixedly connected to the top plate via a support column. A lower die is bolted to the upper surface of the base. A support is fixed inside the lower die, and an ejection mechanism is installed inside the support. A locking mechanism is installed inside the lower die. The lower die has a clearance fit with the outer wall of the die core. The top plate is fixedly connected to the outer wall of a hydraulic cylinder. Existing forging dies have complex upper die structures. Adjusting the overall height of the upper die often requires disassembling and replacing internal components to adapt to the height adjustment. Due to the large number of parts inside the upper die, disassembly and assembly are time-consuming; furthermore, the heavy weight of the components makes disassembly laborious. Therefore, a die with a rapidly adjustable closed height is needed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a mold for quickly adjusting the closed height. This invention uses a threaded connection to install the upper mold body, which facilitates the adaptation and adjustment of the overall height of the upper mold assembly.

[0004] The objective of this invention is achieved through the following technical solution: a mold for quickly adjusting the closed height, comprising an upper mold base and a mold fixing adapter, wherein a fastener for fixing the upper mold base and the mold fixing adapter is provided between the two; the mold fixing adapter is provided with a first countersunk hole for installing the fastener, the fastener passes through the mold fixing adapter and extends into the upper mold base; the fastener is threadedly connected to the upper mold base, and the mold fixing adapter is provided with an upper mold body threadedly connected thereto.

[0005] Preferably, the upper mold base is provided with a second countersunk hole for installing a mold fixing adapter, and the protrusion of the mold fixing adapter extends into the second countersunk hole; the outer contour of the second countersunk hole is adapted to the outer contour of the mold fixing adapter.

[0006] The second countersunk hole facilitates the installation of the mold fixing adapter; at the same time, the second countersunk hole can limit the axial and radial movement of the mold fixing adapter.

[0007] Preferably, the mold fixing adapter includes a mounting flange, which has a first countersunk hole and a first through hole, and the first countersunk hole and the first through hole are interconnected; fasteners for fixing the two are provided between the mounting flange and the upper mold base.

[0008] Preferably, the fastener is a bolt, and the first countersunk hole and the first through hole are arranged coaxially; the inner diameter of the first through hole is 18mm, and the inner diameter of the first countersunk hole is 28mm; the outer contour of the fastener is adapted to the outer contour of the first through hole.

[0009] Preferably, a gap is left between the upper end face of the mounting flange and the lower end face of the upper mold base.

[0010] The mounting flange and mold fixing adapter are integrally molded, resulting in a more stable structure. The first through hole and the first countersunk hole on the mounting flange facilitate the installation of fasteners into the upper mold base. By adjusting the depth of the fasteners installed into the upper mold base, the vertical distance between the mold fixing adapter and the upper mold base can be adjusted.

[0011] Preferably, the fastener is a bolt, and the upper mold base is provided with a threaded hole for installing the fastener.

[0012] By setting threaded holes, the upper mold base and fasteners are more secure, and the installation depth of the fasteners can be easily adjusted.

[0013] Preferably, the outer wall of the upper mold body is provided with external threads, and the mold fixing adapter is provided with internal threads for installing the upper mold body; the size of the external threads and the size of the internal threads are adapted to each other.

[0014] By setting external and internal threads, the upper mold body can be rotated easily, thus allowing for adjustment of the vertical distance between the upper mold body and the mold fixing adapter.

[0015] Preferably, the side of the upper mold body is provided with a plurality of mounting holes for mounting force bars; each mounting hole is evenly distributed on the side wall of the upper mold body.

[0016] By setting mounting holes, it is convenient to install force bars in the mounting holes. By pushing the force bars, the operator can easily control the rotation of the upper mold body relative to the mold fixing adapter, thus adapting and adjusting the vertical distance between the upper mold body and the mold fixing adapter.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The overall vertical height of the mold can be adjusted by rotating the upper mold body, and the adjustment speed is fast; 2. When adjusting the height, only the upper mold body needs to be rotated; the upper mold body is provided with holes for installing force bars, making the adjustment process more labor-saving; 3. The mold has fewer overall parts and is assembled as a whole. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figures 1 to 2 As shown, this embodiment discloses a mold for quickly adjusting the closed height, including an upper mold base 1 and a mold fixing adapter 2. A fastener 3 for fixing the upper mold base 1 and the mold fixing adapter 2 is provided between them. The mold fixing adapter 2 is provided with a first countersunk hole 4 for installing the fastener 3. The fastener 3 passes through the mold fixing adapter 2 and extends into the upper mold base 1. The fastener 3 is threadedly connected to the upper mold base 1. The mold fixing adapter 2 is provided with an upper mold body 5 that is threadedly connected to it.

[0020] The upper mold base 1 has a second countersunk hole 6 for mounting a mold fixing adapter 2. The protrusion of the mold fixing adapter 2 extends into the second countersunk hole 6. The outer contour of the second countersunk hole 6 is adapted to the outer contour of the mold fixing adapter 2. The mold fixing adapter 2 includes a mounting flange 21, which has a first countersunk hole 4 and a first through hole 7, which are interconnected. A fastener 3 for fixing the mounting flange 21 and the upper mold base 1 is provided. The fastener 3 is a bolt. The first countersunk hole 4 and the first through hole 7 are coaxially arranged. The inner diameter of the first through hole 7 is 18 mm, and the inner diameter of the first countersunk hole 4 is 28 mm. The outer contour of the fastener 3 is adapted to the outer contour of the first through hole 7. A gap is left between the upper end face of the mounting flange 21 and the lower end face of the upper mold base 1. The fastener 3 is a bolt, and the upper mold base 1 has a threaded hole 8 for mounting the fastener 3. The outer wall of the upper mold body 5 is provided with an external thread 9, and the mold fixing adapter 2 is provided with an internal thread 10 for installing the upper mold body 5; the size of the external thread 9 and the size of the internal thread 10 are adapted to each other.
