Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile part manufacturing equipment, and in particular relates to a full-automatic glue injection mold for new energy automobile parts. BACKGROUND

[0002] The parts of a new energy automobile include plastic parts, and the plastic parts are usually made by glue injection molds.

[0003] Some existing glue injection molds are mainly composed of an upper mold and a lower mold. In use, the upper and lower molds are closed to form a part cavity (a cavity with a required part shape), then molten plastic is injected into the cavity, and the plastic gradually cools and solidifies in the cavity. When the plastic solidifies into a required part, the upper and lower molds are opened, and the part is ejected from the lower mold by an ejection mechanism in the lower mold. Through the above action, the required part is obtained.

[0004] However, in the above process, since the molten plastic needs to be injected into the part cavity through the injection hole in the upper mold, a certain amount of molten plastic will remain in the injection hole after the injection of the plastic in the part cavity is completed, and the plastic in the injection hole will cool and solidify synchronously with the plastic in the part cavity. Therefore, after the subsequent part is removed, the plastic at the position corresponding to the injection hole on the part needs to be cut, and then the part can be polished, assembled and the like, which affects the production efficiency of a single part. SUMMARY

[0005] The application provides a full-automatic glue injection mold for new energy automobile parts, which has the advantages that the part can be removed without cutting excess material, thereby solving the problem that the production efficiency of a single part is affected by the cutting of excess material.

[0006] To achieve the above object, the application adopts the following technical scheme: a full-automatic glue injection mold for new energy automobile parts, comprising a base, a lower mold fixedly installed on the upper surface of the base, a top plate provided above the lower mold, a vertical plate fixedly and commonly installed between the top plate and the base and located on both sides of the lower mold, an upper mold provided between the lower mold and the top plate, the upper mold and the lower mold jointly forming a part cavity, a lifting rod fixedly installed in the interior of the top plate, an output rod of the lifting rod connected with the upper mold, an injection hole provided in the interior of the upper mold, the injection hole corresponding to the lowest part of the part cavity, the lower side of the injection hole communicated with the part cavity, and the upper side of the injection hole protruding from the upper mold and communicated with an injection mechanism.

[0007] The upper mold consists of a fixed ring and a rotating seat. The rotating seat is installed on the inner side of the fixed ring in a sealing and rotatable manner. The output rod of the lifting rod is fixedly connected to the fixed ring. The injection hole is opened in the rotating seat. A motor is provided above the rotating seat. A connecting rod is fixedly installed between the motor and the output rod of the lifting rod. The output shaft of the motor is connected to the center position of the rotating seat.

[0008] Furthermore, an ejection mechanism is fixedly installed inside the lower mold and below the groove. The ejection mechanism includes a No. 1 electric telescopic cylinder and an ejection block. The ejection block forms a sealed sliding connection with the inside of the lower mold, and the output rod of the No. 1 electric telescopic cylinder is fixedly connected to the ejection block.

[0009] Furthermore, an exhaust hole is provided inside the upper mold, and the exhaust hole corresponds to the highest point of the component cavity. The lower side of the exhaust hole is connected to the component cavity, and the upper side of the exhaust hole protrudes from the upper mold and is connected to the external environment. The exhaust hole is provided in the rotating seat.

[0010] Furthermore, the rotating seat includes an upper rotating body and a lower rotating body, the outer side surface of the upper rotating body forms a sealed rotating connection with the inner side surface of the fixed ring, the upper side surface of the lower rotating body forms a sealed rotating connection with the lower side surface of the upper rotating body, and the interior of the upper rotating body and the interior of the lower rotating body are jointly provided with a moving mechanism, and the step-by-step movement of the lower rotating body and the upper rotating body is realized by the moving mechanism, and the output shaft of the motor passes through the upper rotating body and forms a fixed connection with the lower rotating body.

[0011] Furthermore, the injection hole includes an upper hole and a lower hole, the exhaust hole and the upper hole are both opened inside the upper rotating body, and the lower hole is opened inside the lower rotating body, and the lower side of the upper hole and the upper side of the lower hole are smoothly transitioned.

[0012] Furthermore, the moving mechanism includes a slot and a block. A slot is provided inside the lower rotating body and between the lower hole and the motor output rod. A block is slidably installed in the slot, and the upper end of the block is fixedly connected to the bottom surface of the upper rotating body.

[0013] Furthermore, a deflection plate is provided above the fixing ring, the outer end of the deflection plate is hingedly fixed to the upper side of the fixing ring, and a notch is provided at the inner end of the deflection plate, which is clamped and fixed to the upper protruding end of the upper hole.

[0014] Furthermore, a No. 2 electrically controlled telescopic cylinder is provided inside the fixed ring and below the deflection plate. The output rod of the No. 2 electrically controlled telescopic cylinder abuts against the lower side of the deflection plate. The rotation and resetting of the deflection plate are achieved by the extension and contraction of the output rod.

[0015] This application has the following beneficial effects:

[0016] The present application provides a fully automatic glue injection mold for new energy vehicle parts. Through the arrangement of the injection hole, the rotating seat and the motor, after the molten plastic is injected into the component cavity, the motor drives the rotating seat and the injection hole to rotate for a period of time, so that the contact time between the plastic in the injection hole and the plastic at a fixed position in the component cavity is shortened, and the connection force between the two when solidifying is reduced. Afterwards, the motor stops, and when the plastic in the component cavity and the injection hole solidifies, the motor rotates briefly, so that the rotating seat drives the plastic in the injection hole to separate from the plastic in the component cavity. Through this action, there is no need to cut the excess material when the component is taken out, thereby reducing the probability of affecting the production efficiency of a single component.

[0017] By setting the upper rotating body, upper hole, lower rotating body and lower hole, after the melted plastic is injected into the component cavity, the motor drives the lower rotating body and the upper rotating body to rotate in sequence, so that the upper hole and the lower hole are separated, and the plastic in the injection hole is distributed in the upper hole and the lower hole. Through this action, the amount of direct contact between the plastic in the injection hole and the plastic in the component cavity is further reduced, so that the connection force between the two when solidifying is further reduced, making it easier to separate the plastic in the subsequent injection hole and the plastic in the component cavity, thereby reducing the probability of affecting the production efficiency of a single component.

[0018] Through the arrangement of the upper rotator, the upper hole, the lower rotator and the lower hole, when the upper hole is separated from the lower hole, the top of the lower hole will be closed by the upper rotator, thereby creating a negative pressure between the top of the lower hole and the plastic in the lower hole. At the same time, the bottom of the upper hole will be closed by the lower rotator. Afterwards, when the plastic in the injection hole is separated from the plastic in the component cavity and the upper mold moves upward, the above-mentioned negative pressure will drive the plastic in the lower hole to move upward synchronously, and the plastic in the upper hole will be driven upward by the lower rotator, thereby preventing the residual material in the injection hole from falling off due to gravity and scratching the component when the upper mold moves upward, so that the quality of the component is not easily affected.

[0029] Embodiment one: please refer to Figures 1-6The utility model provides a new energy automobile parts full -automatic glue injection mould, including base 1, the upper surface of base 1 is fixedly installed with lower mould 2, the upper surface of lower mould 2 is seted up with recess, the upper position of lower mould 2 is provided with top plate 4, and the both sides position between top plate 4 and base 1 and located lower mould 2 are all provided with vertical plate 5, and the upper side of vertical plate 5 is fixedly connected with the downside of top plate 4, and the downside of vertical plate 5 is fixedly connected with the upside of base 1, and the position between lower mould 2 and top plate 4 is provided with upper mould 6, and the downside of upper mould 6 is provided with protruding portion, and upper mould 6 and lower mould 2 jointly enclose part cavity, and the inside of top plate 4 is fixedly installed with lifting rod 7 (such as existing electric control telescopic cylinder), and the output rod of lifting rod 7 is connected with upper mould 6, and the inside of upper mould 6 is seted up with exhaust hole 8 and injection hole 9, and exhaust hole 8 corresponds the highest place of part cavity, and the downside of exhaust hole 8 is communicated with part cavity, and the upside of exhaust hole 8 protrudes upper mould 6, and is communicated with outside environment, and injection hole 9 corresponds the lowest place of part cavity, and the downside of injection hole 9 is communicated with part cavity, and the upside of injection hole 9 protrudes upper mould 6, and is communicated with injection mechanism (injection mechanism is prior art, such as injection molding machine, not shown in the drawing, when injection mechanism removes, the upside of injection hole 9 is communicated with outside environment), and upper mould 6 is composed of fixed ring 60 and rotating seat 61, and rotating seat 61 is sealingly rotatably installed in the inside of fixed ring 60, and the output rod of lifting rod 7 is fixedly connected with fixed ring 60, and exhaust hole 8 and injection hole 9 are all seted up in rotating seat 61, and the above of rotating seat 61 is provided with motor 10, and the output rod of lifting rod 7 is provided with connecting rod 11 between motor 10, and one end of connecting rod 11 is fixedly connected with motor 10, and the other end of connecting rod 11 is fixedly connected with the output rod of lifting rod 7, and the output shaft of motor 10 and the central position of rotating seat 61 form fixed connection.

[0030] In use, the lifting rod 7 drives the fixed ring 60 and the rotating seat 61 to move downward until the lower mold 2 forms a part cavity, then the injection mechanism injects molten plastic into the part cavity through the injection hole 9, so that the molten plastic gradually expels the air in the part cavity from the exhaust hole 8 to the outside environment, when the molten plastic is injected into the part cavity, the injection mechanism is removed, and the motor 10 is operated for a period of time, so that the motor 10 drives the rotating seat 61, the injection hole 9 and the exhaust hole 8 to rotate for a period of time, so that the contact time between the plastic in the injection hole 9 and the plastic in the fixed position in the part cavity is shortened, and the connection force when the two are solidified is reduced, then the motor 10 stops, after a period of time, when the plastic in the part cavity and the injection hole 9 is solidified, the motor 10 is temporarily rotated, so that the rotating seat 61 drives the plastic in the injection hole 9 to separate from the plastic in the part cavity, through this action, when the part is taken out, there is no need to cut the excess material, thereby reducing the probability that the production efficiency of a single part is affected, finally, the motor 10 is stopped, and then the lifting rod 7 drives the upper mold 6 to move upward to reset.

[0031] Please refer to Figures 1-6The ejecting mechanism 3 is fixedly installed in the inside of the lower mold 2 and below the recess, and comprises a No. 1 electric control telescopic cylinder and an ejecting block. The ejecting block is in sealed sliding connection with the inside of the lower mold 2, and the output rod of the No. 1 electric control telescopic cylinder is fixedly connected with the ejecting block.

[0032] When the upper mold 6 is separated from the lower mold 2, the No. 1 electric control telescopic cylinder of the ejecting mechanism 3 drives the ejecting block to move upward, and the component in the lower mold 2 is ejected, thereby facilitating the removal of the component.

[0033] Embodiment two: please refer to Figures 1-6 The present embodiment is a further improvement of the embodiment one, and the improvement is that the rotating seat 61 comprises an upper rotating body 610 and a lower rotating body 611, the injection hole 9 comprises an upper hole 90 and a lower hole 91, the outer side surface of the upper rotating body 610 is in sealed rotating connection with the inner side surface of the fixed ring 60, the upper side surface of the lower rotating body 611 is in sealed rotating connection with the lower side surface of the upper rotating body 610, the output shaft of the motor 10 penetrates through the upper rotating body 610 and is fixedly connected with the lower rotating body 611, the exhaust hole 8 and the upper hole 90 are both arranged in the inside of the upper rotating body 610, the lower hole 91 is arranged in the inside of the lower rotating body 611, and the lower side of the upper hole 90 and the upper side of the lower hole 91 are in smooth transition.

[0034] After the molten plastic is injected into the part cavity through the upper hole 90 and the lower hole 91, the motor 10 first drives the lower rotating body 611 to rotate, so that the upper hole 90 and the lower hole 91 are separated, and the plastic in the injection hole 9 is distributed in the upper hole 90 and the lower hole 91. Through this action, the amount of direct contact between the plastic in the injection hole 9 and the plastic in the part cavity is further reduced (the pressure of the plastic in the injection hole 9 on the plastic in the part cavity is reduced, resulting in a weakening of the penetration bonding force between the two), which further reduces the connection force when the two are solidified, making it easier for the plastic in the injection hole 9 and the plastic in the part cavity to be separated, thereby reducing the probability that the production efficiency of a single part will be affected. In addition, when the upper hole 90 and the lower hole 91 are separated, the top end of the lower hole 91 is closed by the upper rotating body 610, so that a negative pressure exists between the top end of the lower hole 91 and the plastic in the lower hole 91. At the same time, the bottom end of the upper hole 90 is closed by the lower rotating body 611. After that, when the plastic in the injection hole 9 and the plastic in the part cavity are separated, and the upper mold 6 moves upward, the above-mentioned negative pressure drives the plastic in the lower hole 91 to move upward synchronously, and the plastic in the upper hole 90 is driven by the lower rotating body 611 to move upward, thereby avoiding the situation that when the upper mold 6 moves upward, the excess material in the injection hole 9 falls off due to gravity and scratches the part, so that the quality of the part is not easily affected. Finally, when the upper mold 6 moves to the limit position, the motor 10 drives the upper hole 90 and the lower hole 91 to communicate, and the collection mechanism is positioned below the injection hole 9, so that the excess material in the injection hole 9 falls into the collection mechanism (or the injection hole 9 can be forced from the top end, so that the internal excess material is forced to separate. This forcing means is prior art and not shown in the figure).

[0035] Please refer to Figures 1-6 A clamping groove 12 is formed in the lower rotating body 611 between the lower hole 91 and the output rod of the motor 10, and a clamping block 13 is slidably installed in the clamping groove 12. The upper end of the clamping block 13 extends out of the clamping groove 12 and is fixedly connected to the bottom surface of the upper rotating body 610.

[0036] First, the lower rotating body 611 drives the clamping block 13 to move until the clamping block 13 contacts the side wall of the clamping groove 12 and drives the upper rotating body 610 to rotate. Through this arrangement, the lower rotating body 611 and the upper rotating body 610 are moved step by step, so that the excess material in the injection hole 9 is smoothly separated.

[0037] Please refer to Figures 1-6, the upper position of the fixed ring 60 is provided with a deflector plate 14, the outer end of the deflector plate 14 is hinged and fixed with the upper side of the fixed ring 60, the inner end of the deflector plate 14 is provided with a notch 15, the notch 15 is clamped and fixed with the upper side protruding end of the upper hole 90, the inside of the fixed ring 60 and below the deflector plate 14 can be provided with a second electric control telescopic cylinder (prior art, not shown in the figure), the output rod of the second electric control telescopic cylinder is in abutment with the lower side of the deflector plate 14, and the rotation and reset action of the deflector plate 14 is realized by the elongation and contraction of the output rod.

[0038] The deflector plate 14 is deflected by manpower or the second electric control telescopic cylinder, so that the notch 15 of the deflector plate 14 clamps the upper side protruding end of the upper hole 90, and then the upper rotating body 610 is fixed, so that when the lower rotating body 611 rotates, the upper rotating body 610 will not have a rotating trend, so that the upper hole 90 and the lower hole 91 can be accurately separated and reset, and the separation and separation of the remaining material in the injection hole 9 are facilitated.
