Description

Technical Field

[0001] The present application relates to the technical field of automobile parts manufacturing equipment, and in particular to a fully automatic glue injection mold for new energy automobile parts. Background Art

[0002] The components of new energy vehicles include plastic components, which are usually made by injection molding.

[0003] Some existing injection molds are mainly composed of an upper mold and a lower mold. When in use, the upper and lower molds are closed to form a component cavity (a cavity with the shape of the required component). Then, the molten plastic is injected into the cavity, so that the plastic gradually cools and solidifies in the above cavity. When the plastic solidifies into the required component, the upper and lower molds are opened, and the component is ejected out of the lower mold through the ejection mechanism inside the lower mold. Through the above actions, the required component is obtained.

[0004] However, in the above process, since the molten plastic needs to be injected into the component cavity through the injection hole inside the upper mold, when the plastic in the component cavity is injected, there will be a certain amount of molten plastic in the injection hole, and it will cool and solidify synchronously with the plastic in the component cavity. As a result, after the subsequent components are taken out, the plastic at the position of the injection hole on the component corresponding to the injection hole needs to be cut. Only then can the components be polished, assembled, etc., resulting in the production efficiency of individual components being affected. Summary of the invention

[0005] The present application proposes a fully automatic glue injection mold for new energy vehicle parts, which has the advantage of not needing to cut the remaining material when the parts are taken out, and is used to solve the problem of additional cutting of the remaining material, which affects the production efficiency of a single part.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a fully automatic glue injection mold for new energy vehicle parts, comprising: a base, a lower mold is fixedly installed on the upper surface of the base, a top plate is arranged above the lower mold, vertical plates are fixedly installed between the top plate and the base and on both sides of the lower mold, an upper mold is arranged between the lower mold and the top plate, the upper mold and the lower mold together form a component cavity, a lifting rod is fixedly installed inside the top plate, the output rod of the lifting rod is connected to the upper mold, an injection hole is opened inside the upper mold, the injection hole corresponds to the lowest point of the component cavity, the lower side of the injection hole is communicated with the component cavity, and the upper side of the injection hole protrudes from the upper mold and is communicated with the injection mechanism; 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 arranged 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.

[0007] Furthermore, an ejection mechanism is fixedly installed inside the lower mold and below the groove. The ejection mechanism includes a No. 1 electrically controlled 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 electrically controlled telescopic cylinder is fixedly connected to the ejection block.

[0008] Furthermore, a vent hole is provided inside the upper mold, the vent hole corresponds to the highest point of the component cavity, the lower side of the vent hole is connected to the component cavity, the upper side of the vent hole protrudes from the upper mold and is connected to the external environment, and the vent hole is provided in the rotating seat.

[0009] 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 fixing 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.

[0010] 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, 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.

[0011] 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. The upper end of the block is fixedly connected to the bottom surface of the upper rotating body.

[0012] 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, and the notch is clamped and fixed to the upper protruding end of the upper hole.

[0013] Furthermore, a No. 2 electrically-controlled telescopic cylinder is arranged 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, and the rotation and resetting of the deflection plate are achieved by extending and contracting the output rod.

[0014] This application has the following beneficial effects: The present application provides a fully automatic glue injection mold for new energy vehicle parts. Through the arrangement of an injection hole, a rotating seat and a motor, when 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, thereby reducing the connection force between the two when solidifying. 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.

[0015] By setting the upper rotating body, the upper hole, the lower rotating body and the 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 turn, so that the upper hole is separated from the lower hole, 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 connecting force between the two when solidifying is further reduced, so that the plastic in the subsequent injection hole and the plastic in the component cavity are easier to separate, thereby reducing the probability of affecting the production efficiency of a single component.

[0016] Through the arrangement of the upper rotating body, the upper hole, the lower rotating body 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 rotating body, 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 rotating body. Afterwards, when the plastic in the injection hole is separated from the plastic in the component cavity and the upper mold moves upward, the negative pressure will drive the plastic in the lower hole to move upward synchronously, and the plastic in the upper hole will be driven to move upward by the lower rotating body, 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.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example 1: Please refer to Figure 1-Figure 6A fully automatic glue injection mold for new energy vehicle parts comprises a base 1, a lower mold 2 is fixedly installed on the upper surface of the base 1, a groove is provided on the upper surface of the lower mold 2, a top plate 4 is arranged above the lower mold 2, and vertical plates 5 are arranged between the top plate 4 and the base 1 and on both sides of the lower mold 2, the upper side of the vertical plate 5 is fixedly connected to the lower side surface of the top plate 4, the lower side of the vertical plate 5 is fixedly connected to the upper side surface of the base 1, an upper mold 6 is arranged between the lower mold 2 and the top plate 4, a convex portion is provided on the lower side surface of the upper mold 6, the upper mold 6 and the lower mold 2 jointly form a component cavity, a lifting rod 7 (such as an existing electric telescopic cylinder) is fixedly installed inside the top plate 4, the output rod of the lifting rod 7 is connected to the upper mold 6, an exhaust hole 8 and an injection hole 9 are provided inside the upper mold 6, the exhaust hole 8 corresponds to the highest point of the component cavity, the lower side of the exhaust hole 8 is connected to the component cavity, and the upper side of the exhaust hole 8 protrudes from the upper mold The upper mold 6 is connected to the external environment, the injection hole 9 corresponds to the lowest point of the component cavity, the lower side of the injection hole 9 is connected to the component cavity, the upper side of the injection hole 9 protrudes from the upper mold 6, and is connected to the injection mechanism (the injection mechanism is a prior art, such as an injection molding machine, not shown in the figure, when the injection mechanism is removed, the upper side of the injection hole 9 is connected to the external environment), the upper mold 6 is composed of a fixed ring 60 and a rotating seat 61, the inner side of the fixed ring 60 is sealed and rotatably installed with the rotating seat 61, the output rod of the lifting rod 7 is fixedly connected to the fixed ring 60, the exhaust hole 8 and the injection hole 9 are both opened in the rotating seat 61, a motor 10 is arranged above the rotating seat 61, a connecting rod 11 is arranged between the motor 10 and the output rod of the lifting rod 7, one end of the connecting rod 11 is fixedly connected to the motor 10, and the other end of the connecting rod 11 is fixedly connected to the output rod of the lifting rod 7, and the output shaft of the motor 10 is fixedly connected to the center position of the rotating seat 61.

[0022] When in use, the lifting rod 7 drives the fixed ring 60 and the rotating seat 61 to move downward until they form a component cavity with the lower mold 2. After that, the injection mechanism injects molten plastic into the component cavity through the injection hole 9, so that the molten plastic gradually squeezes the air in the component cavity out of the exhaust hole 8 to the external environment. After the molten plastic is injected into the component 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 at the fixed position in the component cavity is shortened, and the connection force between the two when solidifying is reduced. After that, the motor 10 stops. After a period of time, when the plastic in the component cavity and the injection hole 9 solidifies, the motor 10 rotates briefly, so that the rotating seat 61 drives the plastic in the injection hole 9 to separate from the plastic in the component cavity. Through this action, when the component is taken out, there is no need to cut the excess material, thereby reducing the probability of affecting the production efficiency of a single component. Finally, the motor 10 is stopped, and then the lifting rod 7 drives the upper mold 6 to move up and reset.

[0023] See also Figure 1-Figure 6An ejection mechanism 3 is fixedly installed inside the lower mold 2 and below the groove. The ejection mechanism 3 includes a No. 1 electric-controlled telescopic cylinder and an ejection block. The ejection block forms a sealed sliding connection with the inside of the lower mold 2, and the output rod of the No. 1 electric-controlled telescopic cylinder is fixedly connected to the ejection block.

[0024] When the upper mold 6 is separated from the lower mold 2, the No. 1 electrically controlled telescopic cylinder of the ejection mechanism 3 drives the ejection block to move upward and ejects the components in the lower mold 2, thereby facilitating the removal of the components.

[0025] Example 2: Please refer to Figure 1-Figure 6 This embodiment is a further improvement of the first embodiment, and the improvement lies in that: the rotating seat 61 includes an upper rotating body 610 and a lower rotating body 611, the injection hole 9 includes an upper hole 90 and a lower hole 91, the outer side surface of the upper rotating body 610 forms a sealed rotating connection with the inner side surface of the fixing ring 60, the upper side surface of the lower rotating body 611 forms a sealed rotating connection with the lower side surface of the upper rotating body 610, the output shaft of the motor 10 passes through the upper rotating body 610 and forms a fixed connection with the lower rotating body 611, the exhaust hole 8 and the upper hole 90 are both opened inside the upper rotating body 610, the lower hole 91 is opened inside the lower rotating body 611, and the lower side of the upper hole 90 and the upper side of the lower hole 91 are smoothly transitioned.

[0026] After the melted plastic is injected into the component 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 is separated from the lower hole 91, 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 component cavity is further reduced (so that the pressure of the plastic in the injection hole 9 on the plastic in the component cavity is reduced, resulting in a weakening of the penetration bonding force between the two), which further reduces the connecting force between the two when solidifying, making it easier to separate the plastic in the subsequent injection hole 9 from the plastic in the component cavity, thereby reducing the probability of affecting the production efficiency of a single component. In addition, when the upper hole 90 is separated from the lower hole 91, the top of the lower hole 91 will be closed by the upper rotating body 610, so that the top of the lower hole 91 and the lower hole 9 1, and at the same time, the bottom end of the upper hole 90 will be closed by the lower rotating body 611. Later, when the plastic in the injection hole 9 is separated from the plastic in the component cavity and the upper mold 6 moves upward, the negative pressure will drive the plastic in the lower hole 91 to move upward synchronously, and the plastic in the upper hole 90 will be driven to move upward by the lower rotating body 611, thereby preventing the residual material in the injection hole 9 from falling off due to gravity and scratching the component when the upper mold 6 moves upward, so that the quality of the component is not easily affected. Finally, when the upper mold 6 moves up to the limit position, the motor 10 drives the upper hole 90 to communicate with the lower hole 91, and makes the collecting mechanism located below the injection hole 9, so that the residual material in the injection hole 9 falls into the collecting mechanism (or force can be applied to the injection hole 9 from the upper end of the injection hole 9, so that the residual material inside is forced to separate, and the force application means is a prior art and is not shown in the figure).

[0027] See also Figure 1-Figure 6 A slot 12 is provided inside the lower rotating body 611 and between the lower hole 91 and the output rod of the motor 10 , in which a block 13 is slidably installed. The upper end of the block 13 extends out of the slot 12 and is fixedly connected to the bottom surface of the upper rotating body 610 .

[0028] First, the rotating 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 setting, the step-by-step movement of the lower rotating body 611 and the upper rotating body 610 is realized, so that the residual material in the injection hole 9 is separated smoothly.

[0029] See also Figure 1-Figure 6A deflection plate 14 is arranged above the fixing ring 60, and the outer end of the deflection plate 14 is hingedly fixed to the upper side surface of the fixing ring 60. A notch 15 is provided at the inner end of the deflection plate 14, and the notch 15 is clamped and fixed to the upper protruding end of the upper hole 90. A No. 2 electrically-controlled telescopic cylinder (existing technology, not shown in the figure) can be arranged inside the fixing ring 60 and below the deflection plate 14. The output rod of the No. 2 electrically-controlled telescopic cylinder abuts against the lower side surface of the deflection plate 14, and the rotation and resetting of the deflection plate 14 are realized by the extension and contraction of the output rod.

[0030] The deflection plate 14 is driven to deflect by manpower or the No. 2 electric telescopic cylinder, so that the notch 15 of the deflection plate 14 is stuck on the upper protruding end of the upper hole 90, thereby fixing the upper rotating body 610, so that when the lower rotating body 611 rotates, the upper rotating body 610 will not have a rotation tendency, so that the upper hole 90 and the lower hole 91 can be accurately separated and reset, which is convenient for the separation and detachment of the remaining material in the injection hole 9.
