Detailed Description
The technical solution of the present invention will be further described with reference to fig. 1 to 5 by way of specific embodiments.
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 5, the top mold 1 is a square plate, the middle of the front surface of the top mold 1 is arched to form a mold injection cavity 1a, an elliptical injection port 1b is arranged at the top of the mold injection cavity 1a, and the injection port 1b penetrates through the whole top mold 1;
one side of the top die 1 is provided with a fixing strip 1c protruding out of the top die 1; the back of the fixed strip 1c is provided with a first elongated mounting groove 1 ca;
the rest three edges of the top die 1 except the fixing strips 1c are provided with a plurality of groups of screw holes 4 around the die injection cavity 1a, and a plurality of first fixing holes 1d are inserted among the screw holes 4;
a bottom die 2; the middle part of the bottom die 2 is raised to form a die bulge 2 a; and the shape of the model bulge 2a is matched with that of the mould injection cavity 1 a; one side of the bottom die 2 is provided with a second mounting groove 2b consistent with the top die 1.
Three edges of the bottom die 2 except the edge provided with the second mounting groove 2b are provided with a plurality of groups of screw holes 4 around the model bulge 2 a; a plurality of second fixing holes 2c are inserted among the screw holes 4; the screw holes 4 of the top die 1 correspond to the screw holes 4 of the bottom die 2 one by one; the first fixing holes 1d correspond to the second fixing holes 2c one to one.
In the embodiment, the top die 1 and the bottom die 2 are locked through the matching of screws and screw holes 4 in the prior art, but in order to prevent the two from being locked or unlocked; a first fixing hole 1d and a second fixing hole 2c are added on the original base layer; in use, a cylinder slightly larger than the first fixing hole 1d is used; inserting the column body into the first fixing hole 1d and the second fixing hole 2c, and locking the first fixing hole 1d and the second fixing hole 2c in an interference manner; the bottom die 2 and the top die 1 can be further locked in the first aspect by locking the first fixing holes 1d and the second fixing holes 2 c; secondly, when demoulding, the time for pulling out the column body is shorter than the time for loosening the screw, so that the time for demoulding can be shortened.
A certain amount of sealing materials can be filled between the first mounting groove 1ca and the second mounting groove 2b, so that on the one hand, the number of screws and the second fixing holes 2c can be reduced, demoulding is facilitated, and on the other hand, the bottom mould 2 and the top mould 1 can be sealed when a mould is manufactured; preventing liquid leakage.
Preferably, the method further comprises the following steps: a strip-shaped adhesive tape 3; the adhesive tape 3 is a high-temperature resistant adhesive tape 3; the adhesive tape 3 is completely attached to the first mounting groove 1ca, and the adhesive tape 3 connects the second mounting groove 2b and the first mounting groove 1 ca.
In this embodiment, the second mounting groove 2b and the first mounting groove 1ca are filled and sealed with a high-temperature resistant adhesive tape 3. Since the injected material has a certain temperature during the casting process, a high temperature resistant object is required, and the adhesive tape 3 has a certain ductility and can be better inserted into the second mounting groove 2b and the first mounting groove 1 ca.
Preferably, the back surface of the top mold 1 is provided with a clamping groove 5a around the mold injection cavity 1a except for the fixing strip 1c, and the clamping groove 5a is positioned between the screw hole 4 and the mold injection cavity 1 a;
the front surface of the bottom die 2 except the edge provided with the second mounting groove 2b is provided with a clamping bulge 5b surrounding the model bulge 2 a; the clamping protrusion 5b is positioned between the model protrusion 2a and the screw hole 4;
and the blocking groove 5a corresponds to the blocking bulge 5 b.
If the blocking groove 5a and the protrusion are not arranged, when the injected liquid is too much, the liquid can directly flow out from the gap between the top die 1 and the top die 1; however, after the detent recesses 5a and the projections are provided, the detent recesses 5a contain the mold injection cavities 1 a; when the injected liquid is too much, the liquid flows into the clamping groove 5a firstly, but the clamping protrusion 5b is correspondingly closed with the clamping groove 5a, so that the sealing property between the top die 1 and the bottom die 2 is enhanced. If the liquid really flows out, the matching of the blocking bulge 5b and the blocking groove 5a can also increase the path of the liquid when flowing out, so that the speed of the liquid flowing out is reduced, and valuable reaction time is given to the staff.
Preferably, the front and back of the mold injection cavity 1a are provided with raised strip-shaped mounting blocks 6a around the injection port 1b, and the front of the fixing strip 1c is provided with raised rectangular mounting blocks 6b at intervals.
The long strip-shaped mounting block 6a on the front surface of the mold injection cavity 1a is used for mounting and fixing the top mold 1; the elongated mounting block 6a of the front face of the mold injection cavity 1a is in the shape for the mold. The rectangular mounting block 6b is used for mounting and fixing the top die 1.
Preferably, the thickness of the top die 1 is 4-6 cm; wherein the thickness of the injection cavity 1a of the mold is 2-3 cm.
Preferably, the thickness of the bottom die 2 is 4-6 cm.
The thicker the mold thickness, the heavier the weight will be, and the heavier the mold will be, the better the top mold 1 will be attached to the bottom mold 2 during the casting process, but the heavier the hydraulic pressure needs to be increased during the demolding process, and the higher the manufacturing cost of the mold will be. The thickness of the top die 1 and the bottom die 2 is 4-6 cm, and the top die 1 and the bottom die 2 are attached to each other in the process of casting and pressing, so that the manufacturing cost of the die can be reduced.
The using method comprises the following steps: before use, the adhesive tape 3 is pressed in the second mounting groove 2b by force, after half of the adhesive tape 3 is placed in the second mounting groove 2b, the top die 1 is pressed, and the first mounting groove 1ca is aligned with the adhesive tape 3; when the adhesive tape 3 is also placed in the first mounting groove 1ca, the column can be inserted into the first fixing hole 1d and the second fixing hole 2 c. In general, the column body may be a deformed body, such as a hard gel-like body, which is reduced in volume by cooling, and is easily inserted into the first fixing hole 1d and the second fixing hole 2c, and when the temperature is returned to normal temperature, the hard gel-like body returns to the previous volume and expands against the first fixing hole 1d and the second fixing hole 2 c. The screw holes 4 are locked by screws, so that the top die 1 and the bottom die 2 can be fixed. The injection port 1b may be filled with a hot-melt plastic during the injection molding.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
