The present invention will be described in further detail with reference to examples.
as shown in fig. 3 to 5, the mold assembly includes a base 201, a mold sleeve 202 is fixedly mounted on the base 201, and a through hole penetrating up and down is formed in the mold sleeve 202, wherein the upper half portion and the lower half portion of the through hole have different shapes to form an upward supporting step surface. In the upper half of the through hole, a mold 203 is placed, where the mold 203 is a groove, and the outside of the mold 203 is a structure with a small top and a large bottom, so that an upward step is formed.
Four threaded holes are formed in the top surface of the die sleeve 202, a die pressing cover 204 is fixedly mounted through screws, and the die pressing cover 204 presses the step of the die 203 downwards, so that the die 203 is positioned and assembled up and down. In order to allow the screws to pass through, the die pressing cover 204 is correspondingly provided with screw through holes 205. A central hole 2041 for the mold 203 to penetrate is formed in the mold gland 204.
In the die sleeves 202 of different specifications, the radial positions of the threaded holes are different, and in order to enable the die press cover 204 in this embodiment to be applicable to the die sleeves 202 of different specifications, as shown in fig. 3 and 5, the die press cover 204 includes a press cover main body, a screw through hole 205 is formed in the press cover main body, the screw through hole 205 is designed as a long hole, the long hole extends from the center position of the die press cover 204 toward the edge position thereof, specifically, the screw through hole 205 is an arc-shaped hole, and the center of the arc-shaped hole is located on one side of the arc-shaped hole toward the center position of the die press cover 204. As shown in fig. 3, the four screw penetration holes 205 each extend obliquely from the center to the edge of the mold gland 204 in the same direction of the circumference of the mold gland 204, which is herein referred to as clockwise or counterclockwise direction of the circumference of the mold gland 204.
After designing the arc-shaped screw through hole 205, the screw through hole 205 can be penetrated by screws with different radial positions, as shown in fig. 3, and can be penetrated into the screw through hole 205 as long as the position of the screw in the radial direction is between the first limit position 206 and the second limit position 207.
When the die press cover 204 is used, the die press cover 204 is placed above the die sleeve 202, and if the diameter of a circle where a threaded hole is located on the die sleeve 202 is large, the die press cover 204 is rotated clockwise in fig. 3, so that the radially outer part of the screw through hole 205 corresponds to the threaded hole of the die sleeve 202; if the diameter of the circle on which the screw hole is formed in the die case 202 is small, the die cover 204 is rotated counterclockwise in fig. 3 so that the radially inner portion of the screw hole 205 corresponds to the screw hole of the die case 202. By the mode, the universality of the die gland 204 can be improved, the die gland 204 can be suitable for die sleeves 202 with different specifications, various types of die glands 204 do not need to be designed and processed, and the design and processing cost is reduced.
Moreover, the screw through hole 205 in this embodiment is an arc-shaped hole, and after the screw is inserted into the screw through hole 205, the hole wall of the arc-shaped hole can be in stop fit with the screw in the radial direction of the mold gland 204, so as to prevent the mold gland 204 from moving in the radial direction, and the hole wall forms a stop inner wall.
As shown in fig. 5, the screw penetration hole 205 is a stepped hole, so that a countersunk groove 2051 is formed in the screw penetration hole 205, the countersunk groove 2051 allowing the head of the screw to be sunk.
It should be noted that the center of the arc-shaped screw hole 205 shown in fig. 5 is located at one side of the screw hole 205 facing the center of the mold cover, and in fact, the center of the screw hole 205 may also be located at the other side of the screw hole 205.
Specific example 2 of the mold assembly of the present invention:
in example 1, the screw penetration hole is an arc-shaped hole. In this embodiment, the screw through hole may be a straight hole, and the straight hole extends obliquely.
Specific example 3 of the mold assembly of the present invention:
in example 1, the screw penetration hole extends obliquely. In this embodiment, the screw penetration hole is a radial hole extending in the radial direction of the die cover.
Specific example 4 of the mold assembly of the present invention:
in example 1, four screw holes are uniformly distributed in the mold gland. In this embodiment, the screw through holes may be three or more than four evenly distributed along the circumferential direction of the mold gland.
The specific embodiment of the die gland of the invention is as follows:
the structure of the mold gland is the same as that of the mold gland in each embodiment of the mold assembly, and the description is omitted here.
Finally, although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments without departing from the inventive concept, or some of the technical features may be replaced with equivalents. 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.
