Hereinafter, an optional dual-cavity glasses leg mold provided by the present invention will be described in more detail with reference to a specific embodiment and its related drawings.
As shown in fig. 1, in a specific embodiment, a mandrel side-drawing mold a is provided, which includes an upper mold plate 10, a lower mold plate 20, an upper mold core 301 and a lower mold core 302 disposed between the upper mold plate 10 and the lower mold plate 20, wherein the upper mold core 301 and the lower mold core 302 form a cavity for molding a product after being closed.
Referring to fig. 2, the mandrel side-drawing die a further includes a side-drawing block 303, an upper drawing block 101, a support 201, and a limit stop 202, wherein the lower die core 302, the upper die core 301, the upper drawing block 101, the side-drawing block 203, the support 201, and the limit stop 202 form a molding module, and the number of the molding modules arranged between the upper die plate 301 and the lower die plate 302 is two, as shown in fig. 1.
The upper template 10 is detachably connected with the upper drawing block 101, and the lower template 20 is detachably connected with the support 201. In the present embodiment, the upper template 10 and the upper pulling block 101, and the lower template 20 and the support 201 are all bolted together.
In each molding module, the side pulling block 303 is disposed on one side of the upper mold core 301 and located between the upper mold plate 10 and the lower mold plate 20, and a mandrel 3031 extending outward is disposed on one side of the side pulling block 303, as shown in fig. 3 and fig. 4, the mandrel 3031 extends into the cavity when the mold is closed, a groove or a protrusion for molding a side structure of a product is disposed on an end surface of the mandrel facing the cavity, and a specific structure is determined according to a structure designed on a side surface of an actual product, which is not described herein again.
As shown in fig. 3 and 4, the upper pulling block 101 is disposed on the lower end surface of the upper die plate 10 and abuts against the side pulling block 303, the support 201 is disposed on the lower die plate 20, and the side pulling block 303 is slidably disposed on the support 201. The lower end face of the upper pulling block 101, which is abutted to the side pulling block 303, is provided with an inclined guide post 1012, the upper end face of the side pulling block 303, which is abutted to the upper pulling block 101, is provided with an inclined sliding hole 3032, and the shape and the size of the inclined guide post 1012 are matched with the inclined sliding hole 3032, so that the inclined guide post 1012 can be inserted into or separated from the inclined sliding hole 3032 in a sliding manner.
With continued reference to fig. 3 and 4, one side of the lower end surface of the upper pulling block 101 abutting against the side pulling block 303 extends downward to form a first guiding inclined surface 1011, and a second guiding inclined surface 3035 is correspondingly arranged on the side pulling block 303. In the present embodiment, as shown in fig. 3 and 4, the first guide slope 1011 and the second guide slope are attached to each other.
When the mold is required to be demolded, the upper pulling block 101 is far away from the side pulling block 303 along with the upper mold plate 10, so that the inclined guide post 1012 slides in the inclined sliding hole 3032 and leaves the inclined sliding hole 3032 to guide the side pulling block 303 to horizontally move towards the side far away from the mold cavity relative to the support 201, and as the inclined guide post 1012 gradually moves upwards, the inclined sliding hole 3032 is pushed by the inclined guide post 1012 to enable the side pulling block 303 to horizontally move outwards, so that the core shaft 3031 is separated from the mold cavity, and then the upper mold core and the lower mold core are separated, so that the product mold is demolded.
When the mold is required to be closed, the upper pulling block 101 is close to the side pulling block 303 along with the upper mold plate 10, so that the inclined guide post 1012 is slidably inserted into the inclined slide hole 3032, and the first guide inclined surface 1011 gradually extrudes the second guide inclined surface 3035 along with the upper pulling block 101 gradually approaching to the side pulling block 303, so as to push the side pulling block 303 to gradually move towards one side of the cavity, and the mandrel 3031 enters the cavity.
Side structures such as product side forming holes or convex strips can be realized through the mandrel side drawing die. The demolding of the mold is convenient, and when the upper mold plate and the lower mold plate are separated, the side pulling block 303 moves outwards along with the movement of the inclined guide pillar 1012 and the inclined sliding hole 3032, and then leaves the cavity to realize demolding. When the mold is closed, the inclined guide post 1012 is slidably inserted into the inclined slide hole 3032, and the first guide inclined surface 1011 pushes the second guide inclined surface 3035 to make the mandrel 3031 enter the cavity, so that the use is convenient.
In order to ensure that the side pumping block 303 can displace along the horizontal direction and move up and down, the bottom of the side pumping block 303 extends towards two sides along the horizontal direction to form two limiting convex parts 3034, a sliding groove 2011 for accommodating the side pumping block 303 is formed in the upper end face of the support 201, two sides of the sliding groove 2011 are provided with limiting grooves 2012 matched with the two limiting convex parts 3034 in structure and arranged along the horizontal direction, the limiting convex parts 3034 are slidably arranged in the limiting grooves 2012, so that the side pumping block 303 is arranged in the sliding groove 2011 of the support 201 and limits the side pumping block 303 to only move along the horizontal direction relative to the support 201, and the phenomenon that the side pumping block 303 moves up and down to cause damage to a product during demoulding is avoided.
Further, in order to avoid damage to the product during the demolding process due to the movement of the upper and lower mold cores during the side demolding, as shown in fig. 2, a limit stopper 202 is disposed on the upper end surface of the lower mold plate 20, and a gate 2021 communicating with the cavity is disposed on the limit stopper 202. Limit stop 202 is provided with protrusion step limit structure, go up mould benevolence 301 and lower mould benevolence 302 and be provided with corresponding indent screens structure respectively, go up the protruding step limit structure of indent screens structure cooperation of mould benevolence 301 and lower mould benevolence 302 for go up mould benevolence 301 and lower mould benevolence 302 and be connected with limit stop 202, in order to restrict the displacement of mould benevolence 301 and lower mould benevolence 302 in the horizontal direction, when guaranteeing to take out piece 303 removal in the side, go up, the lower mould benevolence keeps relative static and ensures that the product can not be impaired.
In this embodiment, as shown in fig. 2, the side block 303 is further provided with an exhaust duct 3033 for exhausting air, so as to ensure smooth matching between the blocks during mold closing.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
