Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a hard alloy porous mold. Background Art

[0002] A multi-hole mold, also known as a multi-cavity mold, is a mold containing multiple cavities that can produce multiple products at a time, thereby improving production efficiency.

[0003] However, there are many defects in the use of porous molds. If a single punch core is damaged, the entire porous mold can only be scrapped, and the production and maintenance costs are high. Therefore, a cemented carbide porous mold is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a cemented carbide porous mold, which has the advantages of saving costs and facilitating the replacement of a single mold core, thereby solving the above-mentioned problems.

[0005] To achieve the above objectives, the utility model provides the following technical solutions: a cemented carbide porous mold, comprising a lower mold, an upper mold is arranged on the top of the lower mold, a mold core is arranged inside the lower mold, and a disassembly component is arranged inside the lower mold.

[0006] Furthermore, the disassembly assembly includes a spring fixedly connected to the inside of the mold core, one end of the spring is fixedly connected to a slide, the end of the slide away from the spring is fixedly connected to a clamping block, a clamping groove is provided inside the lower mold, an oblique opening is provided on the outer surface of the lower mold, and a handle is fixedly connected to the top of the slide.

[0007] Furthermore, the lower mold is internally threaded with a bolt, and the bolt passes through the upper mold.

[0008] Furthermore, the cross-section of the clamping block is trapezoidal, the cross-section of the clamping slot is trapezoidal, the inclined surfaces of the oblique opening, the clamping block and the clamping slot have the same inclination angle, and the clamping block is clamped inside the clamping slot.

[0009] Furthermore, a slot is provided inside the upper mold, and the handle is located inside the slot.

[0010] Furthermore, the mold core consists of a first half mold and a second half mold.

[0011] Furthermore, a sliding groove is provided inside the first half mold, and a sliding block is fixedly connected to a side of the second half mold close to the first half mold, and the cross-section of the sliding block is trapezoidal.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] When the carbide porous mold needs to install the mold core, the slider is clamped into the slide groove, and the mold core is clamped into the lower mold. When the clamping block contacts the bevel, the clamping block will be squeezed to the side close to the spring. When the mold core is completely clamped into the lower mold, the spring will drive the slide plate and the clamping block to reset and clamp the clamping block into the clamping groove, so that the mold core is clamped. When one of the mold cores is damaged, the damaged mold core can be taken out, and the handle is moved to drive the slide plate to move the compressed spring to disengage the clamping block and take out the mold core.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 In this embodiment, a porous cemented carbide mold includes a lower mold 1, an upper mold 2 is disposed on top of the lower mold 1, a mold core 101 is disposed inside the lower mold 1, and a disassembly assembly 3 is disposed inside the lower mold 1. A bolt 201 is threadedly connected to the interior of the lower mold 1 and extends through the upper mold 2.

[0021] Among them, the disassembly component 3 includes a spring 301 fixedly connected to the inside of the mold core 101, one end of the spring 301 is fixedly connected to a slide 302, the end of the slide 302 away from the spring 301 is fixedly connected to a clamping block 303, a clamping slot 304 is opened inside the lower mold 1, an oblique opening 305 is opened on the outer surface of the lower mold 1, a handle 306 is fixedly connected to the top of the slide 302, an empty slot 307 is opened inside the upper mold 2, and the handle 306 is located inside the empty slot 307.

[0022] Secondly, the cross-sectional shape of the card block 303 is a trapezoid, and the cross-sectional shape of the card slot 304 is a trapezoid. The inclined opening 305, the card block 303 and the inclined surface of the card slot 304 are all inclination angles the same. When the card block 303 contacts the inclined opening 305, the card block 303 will be squeezed toward the side close to the spring 301, and the card block 303 will be locked into the inside of the card slot 304.

[0023] In addition, the mold core 101 is composed of a first mold half 1011 and a second mold half 1012, which facilitates replacement of one mold half and saves costs. A slide 1014 is provided within the first mold half 1011, and a slider 1013 is fixedly connected to the side of the second mold half 1012 near the first mold half 1011. The slider 1013 has a trapezoidal cross-section.

[0024] The working principle of the above embodiment is:

[0025] When the core 101 of the carbide porous mold needs to be installed, the slider 1013 is clamped into the slide groove 1014, and the core 101 is clamped into the lower mold 1. When the clamping block 303 contacts the bevel 305, the clamping block 303 will be squeezed to the side close to the spring 301. When the core 101 is completely clamped into the lower mold 1, the spring 301 will drive the slide plate 302 and the clamping block 303 to reset and clamp the clamping block 303 into the clamping groove 304, so that the core 101 is clamped. When one of the cores 101 is damaged, the damaged core 101 can be taken out, and the moving handle 306 drives the slide plate 302 to move the compressed spring 301, so that the clamping block 303 is disengaged from 304 and the core 101 can be taken out.
