DETAILED DESCRIPTION

[0033] In order to make the person skilled in the art better understand the technical scheme, the technical scheme of the utility model is clearly and completely described below in combination with the drawings and examples.

[0034] The structure, proportion, size and the like shown in the drawings of the specification are only used to cooperate with the content disclosed in the specification, and are not used to limit the limiting conditions of the utility model that can be implemented, so they do not have substantial technical significance, any modification of structure, change of proportion relationship or adjustment of size, without affecting the effect and purpose that the utility model can produce, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "rear", "left" and "right" in the specification are only for the convenience of clear understanding of the description, and are not used to limit the scope of implementation, the change or adjustment of relative relationship is also regarded as the scope of implementation of the utility model without substantial change of technical content.

[0035] The decomposing demolding structure of the existing rubber plug forming die group is divided into at least two parts, which is installed on the machine table and is not integrated with other parts of the die. The harver middle die is difficult to position using this structure, is greatly affected by manual misoperation, and the harver middle die and the lower die core are often damaged, the service life of the die is very low, and the production capacity of the product is also greatly limited.

[0036] The basic idea of the utility model is to integrate the decomposing demolding member to position the harver middle die from all directions, prevent damage to the harver middle die and the lower die during demolding, and prolong the service life of the die.

[0037] As shown in Figs. 1 to 3 The utility model discloses an integrated decomposing demolding member for rubber plug forming die group, which comprises a square frame 5, the front and rear sides of the square frame 5 are provided with through holes, and a positioning pin can be connected with the lower die 4 of the rubber plug forming die group through the through holes; the left and right sides of the square frame 5 are used for supporting the harver middle die 3.

[0038] For the convenience of description, it is assumed that when the operator faces the square frame, the side far from the operator is the front side of the square frame, the side close to the operator is the rear side, the side on the left hand is the left side, and the side on the right hand is the right side. The square frame 5 is mainly used for carrying the Haver middle mold 3, the two ends of the Haver middle mold are carried on the side edges of the left and right sides of the square frame 5, and the Haver middle mold can slide back and forth along the two side edges of the square frame. A rubber plug product is placed in the Haver middle mold, and opening and turning the Haver middle mold can unload and collect the rubber plug products one by one.

[0039] The integrated disassembly and demolding member further comprises: a limiting boss 51 integrally arranged above the left and right side edges of the square frame 5 for limiting the displacement of the Haver middle mold 3 in the left and right directions; and a fixed block 52 fixedly arranged at the end of at least one of the left and right side edges of the square frame 5, so that the fixed block 52 can position the Haver middle mold 3 in the front and back directions.

[0040] The limiting boss 51 is integrally formed with the square frame, and the limiting boss can be regarded as a part of the frame body. Of course, a limiting boss can be made, and then it is fastened and connected with the square frame. If a detachable connection mode is adopted, when the limiting boss is deformed or damaged, a new limiting boss can be replaced and installed on the square frame, saving economic cost.

[0041] The limiting boss 51 is arranged in a long strip shape above the left and right side edges of the square frame 5, and the distance between the side walls of the two limiting bosses is just equal to the length of the Haver middle mold. Therefore, the limiting boss forms a limit in the left and right directions of the Haver middle mold.

[0042] Preferably, the upper surface of the limiting boss 51 is lower than the upper surface of the end of the Haver middle mold 3 in the vertical direction. In this way, the end of the Haver middle mold can be easily held during the disassembly and demolding process, and the efficiency of collecting rubber plugs is improved. Of course, it cannot be too low, if the upper surface of the boss 51 is lower than the lower surface of the end of the Haver middle mold 3 in the vertical direction, then the boss will be difficult to limit the Haver middle mold 3 in the left and right directions, which must be avoided. The size of the upper surface of the boss 51 lower than the upper surface of the end of the Haver middle mold 3 in the vertical direction is less than or equal to 2 mm, within this range, the Haver middle mold 3 can be firmly limited in the left and right directions, and the operator can easily hold and control the Haver middle mold, improving the demolding efficiency.

[0043] The fixed block 52 is fixedly arranged at the end of at least one of the two side edges of the left and right sides of the square frame 5, so that the fixed block 52 can position the Haver middle die 3 in the front-back direction. It can be arranged at the front end of the left side edge of the square frame, or at the front end of the right side edge, or one at the front end and one at the rear end of the left side edge, and one at the front end and one at the rear end of the right side edge, all of which can play a limiting role in the front-back direction of the Haver middle die 3. Of course, if the fixed block 52 is arranged at the front end of the left and right sides of the square frame, it limits the Haver middle die 3 in the front-back direction from the front end; if the fixed block 52 is arranged at the rear end of the left and right sides of the square frame, it limits the Haver middle die 3 in the front-back direction from the rear end. Preferably, the fixed block 52 is fixedly arranged at the end of the left and right side edges of the square frame 5; further preferably, the fixed block 52 is fixedly arranged at the end of the left and right side edges of the square frame 5 close to the front side edge of the square frame 5.

[0044] The front view of the fixed block 52 at least partially overlaps the front view of the Haver middle die 3 in the left-right direction. If it cannot partially overlap, when the Haver middle die 3 is pushed forward to the most forward position, it cannot be in contact with the fixed block, and naturally the fixed block cannot limit the Haver middle die 3 in the front-back direction.

[0045] Of course, it should be noted that before disassembly and demolding, the two front and rear baffles integrally connected with the lower die and other parts of the mold can also form actual limiting action on the Haver middle die. This will not be described in detail.

[0046] The fixed block 52 movably connects a pressing plate 54, which is configured to be pressed against the end of the Haver middle die 3 when it is horizontally placed, and the pressing plate 54 can play a pressing and fixing role on the Haver middle die 3. When disassembling and demolding, the pressing plate 54 can be removed from the fixed block 52, and after demolding is completed, the pressing plate 54 can be connected with the fixed block 52 as needed, and then the pressing plate 54 is pressed against the end of the Haver middle die 3.

[0047] In order to avoid repeatedly taking and placing the pressing plate, the pressing plate 54 can be hinged to the fixed block 52, and the pressing plate 54 can rotate in the vertical plane with the fixed block 52 as the axis. In this way, when the half die 3 needs to be pressed, the pressing plate 54 can be placed down, and when pressing is not needed, the pressing plate can be lifted up from the free end, and the connection between the pressing plate 54 and the fixed block 52 can still be maintained without the need to disassemble the pressing plate 54 from the fixed block 52. When the horizontal plane is the bottom surface, the angle of rotation of the pressing plate 54 is between 90 degrees and 150 degrees, and the pressing plate can be lifted up by 90 degrees to 150 degrees, and the pressing plate can be balanced under the action of its own gravity without the need for external force support. Of course, when the maximum angle of rotation of the pressing plate is greater than 150 degrees, although a larger working space is occupied, it does not affect the normal use of the pressing plate.

[0048] The cooperation gap between the limiting boss 51 and the half die 3 in the left-right direction is between 0.5 mm and 3.0 mm, and the cooperation gap between the fixed block 52 and the half die 3 in the front-rear direction is between 0.5 mm and 3.0 mm. Preferably, the cooperation gap between the half die 3 and the limiting boss 51 in the left-right direction is between 0.5 mm and 1.5 mm, and the cooperation gap between the half die 3 and the fixed block 52 in the front-rear direction is between 0.5 mm and 1.5 mm, and the half die 3 can be accurately limited. When the cooperation gap is between 1.5 mm and 3.0 mm, the cooperation gap is slightly loose, the half die is not accurately limited, and only the mold life and the production capacity of the product can be slightly improved.

[0049] In addition, the integrated disassembly and demolding member further comprises a stop block 53 fixedly arranged at the left and right ends of the rear side of the square frame 5, which can effectively prevent the half die 3 from falling off during disassembly and demolding.

[0050] Another aspect of the present application relates to a rubber plug forming mold module, which is provided with an injection plug 1, an upper mold 2, a Haver middle mold 3 and a lower mold 4 from top to bottom, the upper mold is provided with an injection cavity 21, an injection hole 22 and an upper mold core 23 for forming an inner hole of the rubber plug, the lower mold is provided with a boss 41 and a lower mold core 42 for forming an outer shape of the rubber plug, and further comprises the integrated disassembly demolding member for the rubber plug forming mold module as described above. The Haver middle mold is widened and thickened, the thickness is not less than 15 mm and the width is not less than 30 mm, and the boss 41 provided on the lower mold is also increased in thickness to prevent the Haver middle mold 3 from being deformed. The cooperation gap between the injection plug 1 and the injection cavity 21 is 0.08-0.12 mm, the cooperation gap between the injection plug 1 and the injection cavity 21 in the vertical direction is 0.1-0.3 mm, the upper end of the injection hole 22 is chamfered with a radius of R0.5-R2 mm, the lower end of the injection hole 22 is a slant hole with a bottom diameter of D0.8-D1.5 mm, and the mold core 23 for forming the inner hole of the rubber plug is integrally processed.

[0051] After the product is formed, the injection plug 1 is separated from the injection cavity 21 to remove the flash in the injection cavity 21, and at the same time, the flash in the injection hole 22 connected with the flash in the injection cavity is removed; then the pressing plate 54 is turned up, the Haver middle mold 3 is separated, the product is taken off, and the stopper 53 prevents the Haver middle mold 3 from falling due to improper operation; after the product is taken off, the Haver middle mold 3 is combined together and pushed to abut against the fixing block 52, and through the positioning of the disassembly demolding member and the lower mold 4, the Haver middle mold 3 can be accurately positioned, the manual operation error is effectively reduced, and the service life of the mold is improved.

[0052] The above description of the present application and its embodiments is illustrative and not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. If a person skilled in the art is inspired by the above description, without departing from the creative purpose of the present application, similar structural modes can be designed without creativity, which are within the protection scope of the present application.
