Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing air-conditioning vents, and in particular to an injection mold and an injection molding method for automobile air-conditioning vents. Background Art

[0002] In the automotive industry, automobile air-conditioning vents are molded according to the size of the parts on the vents by injection molding equipment, and then injection molded by the injection molding equipment. The air-conditioning vents are connected to multiple adjustable baffles and the vent frame, and their shapes are set according to needs. When producing the vent frame, the upper and lower molds are set according to the size, and then injection molding is performed.

[0003] The Chinese patent with application number "202122027731.3" and name "A Automobile Air-conditioning Outlet Injection Mold" can, by setting an intermediate plate and corresponding structural coordination, make it possible for the upper end of the air-conditioning outlet in the molding cavity to protrude above the fixed mold after the intermediate plate is separated from the fixed mold during demolding, making it convenient to remove the air-conditioning outlet in the molding cavity and facilitate demolding.

[0004] The shortcomings of the existing technology are: in the existing technology, after the air outlet frame is injection molded, it is first demolded, and then the demolded air outlet frame is transported to the assembly line through corresponding pushing equipment or manually, but the demolding of the existing injection molding equipment is not ideal. For example, the above-mentioned patent uses a protruding part of the air outlet, but it is still necessary to put the injection molding device in a stagnant state before taking it out. Its demolding efficiency is still not high, resulting in a waste of waiting time. Summary of the Invention

[0014] Preferably, the locking mechanism includes a first lock buckle and a first elastic member horizontally slidably arranged on the telescopic rod, one end of the first elastic member abuts against the first lock buckle, and when the first lock buckle is clamped in a groove opened on the first support cross bar, the telescopic rod and the first support cross bar can be locked relative to each other.

[0015] Preferably, the unlocking assembly includes a second lock buckle slidably set on the base, and a third elastic member is provided in the groove in which the second lock buckle slides, and its elastic force is greater than that of the first elastic member, so that when the second lock buckle conflicts with the first lock buckle, it can drive the first lock buckle to retract into the telescopic rod.

[0016] Preferably, a fourth elastic member is provided between the telescopic rod and the first supporting cross bar, and under the elastic force of the fourth elastic member, the telescopic rod has a tendency to move toward the injection molding groove.

[0017] Preferably, the first supporting cross bar, the second supporting cross bar and the telescopic rod are all slidably and sealingly connected to the injection molding groove.

[0018] Preferably, the top of the vertical rod passes through and extends into the injection molding groove, and an oblique support assembly is provided on the top, wherein the oblique support assembly includes an elastic plate elastically hinged to the top of the vertical rod, and the hinge elastic force causes the elastic plate to tilt toward the conveyor belt;

Then, after moving downward, it can drive the other end of the transmission rod to move upward, so that the driving plate under the other injection groove moves upward, which can drive the support on the driving plate to move upward, and thus the air outlet frame that has been completed by injection molding in the injection groove can be lifted up to achieve demolding.

[0042] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

The words “including” or “comprising” and the like used in this disclosure mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The words “connected” or “connected” and the like are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. “Up”, “down”, “left”, “right” and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0044] Refer to 1-12, an injection mold and injection molding method for an automobile air conditioner outlet, comprising a base 1, a support crossbar fixedly disposed on the base 1, an upper die 12 slidably disposed on the support crossbar, two injection slots 101 adapted to fit the upper die 12, a conveyor belt 3 disposed adjacent to the base 1, and the following:

[0045] The number of the driving plates 5 corresponds to the number of the injection molding slots 101 , and the driving plates 5 are vertically slidably arranged in the base 1 , and the driving plates 5 are provided with support members for lifting the air outlet frame;

[0046] The transmission rod 54 is hinged in the base 1. The two ends of the transmission rod 54 are movably provided with vertical rods 4, which vertically extend into the injection molding groove 101. The two ends of the transmission rod 54 are respectively in contact with the two driving plates 5.

[0047] During injection molding, the upper mold 12 is embedded in the injection molding groove 101 and presses the vertical rod 4 to drive the other end of the transmission rod 54 to lift up, so that the support member on the other driving plate 5 moves upward and lifts the air outlet frame. Figure 8 and Figure 9As shown, the two ends of the transmission rod 54 respectively contact the bottom of the driving plate 5. When one end is pressed down, the driving plate 5 on the other end will be driven to move upward, and the downward pressure is the downward pressure on the forward rod generated by pressing the vertical rod 4 when the upper die 12 is pressed downward. Specifically, the upper die 12 can slide along the supporting cross bar, that is, it can inject two injection grooves 101 at a time, and then the upper die 12 is provided with a telescopic rod 511 that moves vertically downward, which can drive the upper die 12 to be pressed down for injection. In this embodiment, the injection stroke and feeding stroke of the upper die 12 are common knowledge and conventional technical means of those skilled in the art, and therefore they are not described one by one.

[0048] By arranging two injection molding grooves 101 on the base 1, and respectively arranging two driving plates 5 below the injection molding grooves 101, and then the two driving plates 5 are used to carry the support parts, that is, the upper mold 12 can be used to press down and inject while the other driving plate 5 can be driven to rise through the transmission rod 54, that is, the support parts can push out the air outlet frame formed in the injection molding groove 101 to achieve complete demoulding, that is, not only can complete demoulding be achieved, but also can be detached through the injection molding stroke of the injection molding machine, that is, the use effect of the device is greatly improved, and injection molding can be carried out continuously, avoiding the injection molding device from being in a stagnant state, and improving the injection molding efficiency.

[0049] Furthermore, the support member includes a third support cross bar 53 relatively arranged at both ends of the driving plate 5, and a second support cross bar 52 is also provided on one side of the upper surface of the driving plate 5. The tops of the second support cross bar 52 and the third support cross bar 53 can be respectively inserted into the injection molding groove 101, and when rising, the air outlet frame can be lifted up. The support member also includes a tilt compensation member fixedly provided on the driving plate 5, and the tilt compensation member includes a first support cross bar 51 fixedly provided on the driving plate 5, and a telescopic rod 511 is slidably and retractably provided on the first support cross bar 51, and the telescopic rod 511 is locked with the first support cross bar 51 by a locking mechanism. When the driving plate 5 is in the base 1, the telescopic rod 511 can be compressed in the first support cross bar 51 under the restriction of the locking mechanism.

[0050] Furthermore, it also includes an unlocking component for unlocking the locking mechanism; after the air outlet frame is injection-molded, the air outlet frame is lifted up by the support member, and the unlocking component acts on the locking mechanism to unlock it, so that the tilt compensation member pops out and drives the air outlet frame to be tilted and slide along its tilt direction onto the conveyor belt 3. The present invention is achieved by Figure 7 As shown, the top ends of the second support cross bar 52 and the third support cross bar 53 are respectively configured to fit into the notch at the bottom of the injection molding groove 101. When not raised, the second support cross bar 52 and the third support cross bar 53 are respectively at the bottom of the injection molding groove 101 and are engaged with the injection molding groove 101. Figure 5As shown, the first support cross bar 51, the second support cross bar 52 and the third support cross bar 53 are respectively located at the bottom of the injection molding groove 101, that is, injection molding can be performed. Then, after injection molding, the support member below the injection molding groove 101 is driven by the injection stroke of another injection molding groove 101 to lift the air outlet frame in the injection molding groove 101 to achieve its demolding.

[0051] Furthermore, the locking mechanism includes a first locking buckle 5111 and a first elastic member 5112 that are horizontally slidably disposed on the telescopic rod 511. One end of the first elastic member 5112 abuts against the first locking buckle 5111. When the first locking buckle 5111 is engaged with a groove formed in the first support crossbar 51, the telescopic rod 511 and the first support crossbar 51 are locked relative to each other. The tilt compensation member provided in the present invention allows the air outlet frame to be lifted up by the support member after injection molding, achieving preliminary complete demolding. The tilt compensation member is then unlocked and applied to one side of the air outlet frame, causing the air outlet frame to be tilted, with the tilt direction toward the conveyor belt 3, thereby enabling the frame to slide along its tilt direction onto the conveyor belt 3. Thus, in this embodiment, the tilt compensation assembly can automatically convey the demolded material onto the conveyor belt 3, facilitating subsequent processing and assembly. That is, the present invention can achieve demolding and automatic sliding of the air outlet frame onto the conveyor belt 3 by the downward movement of the upper die 12, thereby achieving high production efficiency.

[0052] In an embodiment further provided by the present invention, the unlocking component includes a second lock buckle 13 slidably set on the base 1, and a third elastic member 14 is provided in the groove in which the second lock buckle 13 slides, and its elastic force is greater than the first elastic member 5112, so that when the second lock buckle 13 conflicts with the first lock buckle 5111, it can drive the first lock buckle 5111 to retract into the telescopic rod 511.

[0053] Furthermore, a fourth elastic member 5113 is provided between the telescopic rod 511 and the first supporting cross bar 51 , and under the elastic force of the fourth elastic member 5113 , the telescopic rod 511 tends to move toward the injection groove 101 .

[0054] Furthermore, the first support cross bar 51, the second support cross bar 52, and the telescopic rod 511 are all slidably and sealingly connected to the injection molding groove 101. Specifically, the first support cross bar 51, the second support cross bar 52, and the telescopic rod 511 provided in the present application can be respectively slidably and sealingly connected to the injection molding groove 101, that is, when the material is injected into the injection molding groove 101, a sealed connection can be achieved so that the material does not leak out. In this embodiment, the sealed sliding connection can adopt a dynamic sealing structure in the prior art, so it is not described in detail one by one.

[0055] Furthermore, the top of the vertical rod 4 passes through and extends into the injection molding groove 101, and an oblique support assembly is provided at the top. The oblique support assembly includes an elastic plate 41 elastically hinged to the top of the vertical rod 4, and the hinge elastic force causes the elastic plate 41 to tilt toward the conveyor belt 3; compensation plates 42 are slidably provided at both ends of the elastic plate 41, and the lower end of the compensation plate 42 is provided with an extrusion rod 411 that passes through the elastic plate 41, and the lower end of the extrusion rod 411 is in contact with the oblique groove 401 opened on the vertical rod 4.

[0056] Specifically, the present embodiment provides an oblique support assembly on the vertical rod 4, so that after demolding, the inclined air outlet frame can be supported by the oblique support assembly on the vertical rod 4 to assist it in sliding, that is, the stability of the air outlet frame when sliding can be greatly increased. Specifically, when the elastic plate 41 is pressed down, the elastic plate 41 rotates along its elastic hinge axis and moves downward, and then when it rotates downward, it can drive the extrusion rod 411 to move into the oblique groove 401, that is, under the action of the oblique groove 401, the extrusion rod 411 contracts inward, that is, the connected compensation plate 42 is also contracted, that is, the compensation plate 42 can be contracted into the elastic plate 41, that is, when the upper mold 12 moves downward for injection molding, the compensation plate 42 will not hinder injection molding; that is, by providing the compensation plate 42, the support range of the air outlet frame can be increased, and after the upper mold 12 is pressed down, the compensation plate 42 can be retracted into the elastic plate 41 by providing the extrusion rod 411.

[0057] In addition, the present invention provides an elastic plate 41 and a compensation plate 42 on the vertical rod 4, so that when the air outlet frame is flushed out, the tilt compensation member and the elastic plate 41 can cooperate to make the lifted air outlet frame tilt and slide onto the conveyor belt 3 through the action of the vertical rod 4 and the elastic plate 41. Figure 1 In the direction of the arrow shown, the air outlet frame slides out of the injection groove and is transported to the conveyor belt 3 in the direction of the arrow, so that the air outlet frame can automatically fall onto the conveyor belt 3 after demoulding.

[0058] When the present invention is in use, the upper die 12 moves along the support cross bar to the position of the corresponding injection groove 101, and performs downward injection molding. After fitting, the upper die 12 fits into the injection groove 101, so that a mold of the injection molding air outlet frame is formed between the upper die 12 and the injection groove 101. Then, the material is fed into the injection groove 101 through a feeding device (not shown in the figure). The feeding port can be opened as follows: Figure 10At point a shown, the material can be injected into the sealed injection molding groove 101, and then the injection molding is performed. When pressing down, the product in the other injection molding groove 101 can be driven out of the injection molding groove 101. Specifically, when pressing down, the vertical rod 4 in the injection molding groove 101 is first pressed down, and then during the pressing process:

[0059] The elastic plate 41 is gradually squeezed, causing the elastic plate 41 to rotate along the axis hinged to the vertical rod 4. During the rotation, the compensation plate provided below the elastic plate 41 gradually moves inward, and then moves downward along the oblique groove 401 through the provided squeezing rod 411, driving the compensation plate to retract inward.

[0060] The vertical rod 4 is pressed down, driving the transmission rod 54 below, so that one end of the transmission rod 54 moves downward, and then after moving downward, it can drive the other end of the transmission rod 54 to move upward, that is, the driving plate 5 below the other injection molding groove 101 moves upward, that is, it can drive the support member on the driving plate 5 to move upward, that is, it can lift up the injection-molded air outlet frame in the injection molding groove 101 to achieve demoulding; at the same time, the vertical rod 4 also moves upward synchronously, that is, the elastic plate 41 and the compensation plate 42 on the injection molding rod also move upward synchronously;

[0061] The tilt compensation component on the other support member is also gradually unlocked. Specifically, after the driving plate 5 moves up, the first support cross bar 51 also moves up at the same time. After the upward movement is completed, the first lock buckle 5111 on the first support cross bar 51 corresponds to the second lock buckle 13. Since the elastic force of the third elastic member 14 is greater than the first elastic member 5112, the second lock buckle 13 can squeeze the first lock buckle 5111, so that the first lock buckle 5111 is completely inserted into the telescopic rod 511. Then the telescopic rod 511 is no longer restricted by the first lock buckle 5111, and the elastic force of the fourth elastic member 5113 causes the telescopic rod 511 to pop out, so that the telescopic rod 511 acts on one side of the air outlet frame, even if the air outlet frame is in a tilted state, and the tilt direction is toward the direction of the conveyor belt 3, so that it can slide along its tilt direction onto the conveyor belt 3, realize the demoulding of the air outlet frame, and slide onto the conveyor belt 3. That is, the demoulding material can be automatically conveyed to the conveyor belt 3 through the provided tilt compensation component, which is convenient for subsequent processing and assembly.

[0062] Furthermore, the present invention also provides an air-conditioning outlet injection molding method, which is applied to the above-mentioned automobile air-conditioning outlet injection mold, specifically comprising the following injection molding steps:

[0063] 1. Pressing mold: The upper pressing mold 12 moves to the top of the injection groove 101 and then moves downward, and the upper pressing mold 12 fits into the injection groove 101.

[0064] 2. Demolding: The vertical rod 4 is pressed down to drive the transmission rod 54 below, so that one end of the transmission rod 54 moves downward. Then, after moving downward, it can drive the other end of the transmission rod 54 to move upward, that is, the driving plate 5 below the other injection groove 101 moves upward, that is, it can drive the support member on the driving plate 5 to move upward, that is, it can lift up the injection-molded air outlet frame in the injection groove 101 to achieve demolding.

[0065] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
