Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the technical solution of the present invention will be further explained by combining the drawings and by means of the specific implementation manner.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used in the orientation or positional relationship shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 2, the embodiment provides a bottle cap forming mold, which includes a bottle cap forming male mold, where the bottle cap forming male mold includes a mold handle 1 and a mold core 2, which are independently disposed, where the mold handle 1 and the mold core 2 are coaxially disposed, the bottle cap forming male mold further includes a fixing member 3, and the fixing member 3 penetrates through the mold handle 1 and the mold core 2 to fix the mold handle 1 and the mold core 2 together. The die shank 1 and the die core 2 in the embodiment are detachably connected through the fixing part 3, and the die core 2 is only replaced when the die core 2 is damaged, so that the whole bottle cap forming male die is not required to be replaced, the cost for maintaining the bottle cap forming male die is low, and the maintenance is convenient.

Specifically, as shown in fig. 2, the fixing member 3 includes a plurality of screws 31, and the screws are screwed into the die shank 1 and the mold core 2 from the outside of the body of the bottle cap forming punch respectively, so as to fix the die shank 1 and the mold core 2, ensure the stability of connection of each part of the bottle cap forming punch in the working process, and ensure the smooth proceeding of the compression molding process. In addition, as shown in fig. 2, the fixing member 3 of the present embodiment further includes a pin 32, and the pin 32 is inserted into the die shank 1 and the core 2 from the outside of the body of the bottle cap forming punch, respectively, so that the stability of the connection between the die shank 1 and the core 2 can be further improved, the core 2 is prevented from falling off from the die shank 1, and the mutual rotation between the core 2 and the die shank 1 can be prevented. The pin 32 in this embodiment may be a square pin or a round pin, and the specific structure of the pin 32 may be selected according to a specific application scenario.

Because let in high-pressure gas in the through-hole of seting up in the bottle lid shaping protruding mould and be used for the bottle lid to demold from core 2, nevertheless mould handle 1 and core 2 respectively and the mounting 3 between can produce the gap, high-pressure gas can flow through the gap to lead to high-pressure gas's pressure not enough, lead to the bottle lid can't follow the smooth drawing of patterns on core 2. In order to solve the above problem, as shown in fig. 2, the bottle cap forming male die further comprises a sealing cover 4, the sealing cover 4 is fixed on the periphery of the body of the bottle cap forming male die and covers the outer end of the fixing part 3, and by arranging the sealing cover 4, high-pressure gas in the bottle cap forming male die can be prevented from leaking to the outside, and the bottle cap can be guaranteed to be smoothly demolded from the mold core 2.

As shown in fig. 3, in order to realize the quick installation and positioning of the die shank 1 and the core 2, the die shank 1 is provided with a mounting hole 11 extending from an end thereof, the shape and size of the mounting hole 11 are the same as those of the outer contour of the core 2, and the core 2 is inserted into the mounting hole 11. In other embodiments, the mold core 2 may also be provided with a mounting hole extending from an end thereof to the inside, the shape and size of the mounting hole are the same as those of the outer contour of the mold handle 1, and the mold handle 1 is inserted into the mounting hole, so that the effect of quickly mounting and positioning the mold handle 1 and the mold core 2 can also be achieved. In order to improve the fixing stability of the die shank 1 and the core 2, the die shank 1 and the core 2 are in interference fit.

Referring to fig. 2, the mounting hole 11 is provided with a limiting portion 111 extending along a radial direction thereof, the limiting portion 111 can limit a depth of the other one of the cores 2 inserted into the mounting hole 11, so that an operator can conveniently grasp that the core 2 and the mold shank 1 are mounted in place, and the core 2 cannot be inserted into the mold shank 1 too deeply or too shallowly. In order to ensure that the core 2 is inserted into the die shank 1 to a sufficient depth and avoid the core 2 from falling off from the die shank 1, the length L from the limiting part 111 to the free end of the mounting hole 11 is not less than 1/2 of the length of the core 2 along the axial direction of the bottle cap forming male die. In addition, in order to achieve a preferable stopper effect of the stopper portion 111 on the core 2, the stopper portion 111 has an annular shape.

It is noted that the basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
