Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp molds, in particular to a vehicle lamp mold provided with a centrifugal demolding structure. Background Technique

[0002] The vehicle lamp mold is mainly the main equipment for producing vehicle lamp covers, and it is processed into the required style by injection molding. For example, in the patent with the publication number "CN213972363U" and the patent name "Automobile lamp cover injection mold", after the injection molding is completed when the female mold and the male mold are closed, the output end of the driving electric push rod presses down the transmission rod, so that the transmission rod deflects along the mounting seat, and thus one end of the transmission rod far away from the output end of the electric push rod tilts up to push the transmission plate. Since a through hole for the cooperation of the connecting rod is opened on the top wall of the installation cavity, and the connecting rod is slidably connected through the top wall of the installation cavity, the transmission plate pushes the connecting rod to slide up along the top wall of the installation cavity, so that the top block pushes the injection molded part processed in the mold groove for demolding; a spray pot is also provided on the side wall of the lower mold base, and a demolding agent is contained inside the spray pot. A small amount of demolding agent can be sprayed into the gap between the female mold and the injection molded part by using the spray pot to assist the top block in demolding the injection molded part, which is more convenient. However, the following problems still exist in the actual use process of the above structure:

[0003] The above structure uses the top block to push and demold the injection molded part processed in the mold groove, but such a demolding method is very easy to damage the shape of the formed vehicle lamp, which in turn causes damage to the vehicle lamp, not only affecting the production quality, but also the top block installed inside will cause redundant edges and corners in the formed mold, and then manual trimming is required later.

[0004] Therefore, we propose a vehicle lamp mold provided with a centrifugal demolding structure, which can well solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide a vehicle lamp mold provided with a centrifugal demolding structure to solve the problem that the current demolding method in the market is very easy to damage the shape of the formed vehicle lamp, which in turn causes damage to the vehicle lamp and affects the production quality proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A vehicle lamp mold provided with a centrifugal demolding structure includes a bottom plate and a top plate arranged above the bottom plate, and the top plate and the bottom plate are connected by vertical rods;

[0007] It further includes: A cylinder is fixed on the upper surface of the top plate, and the lower end of the cylinder penetrates through the top plate and is fixed to the upper mold. A lower mold is arranged below the upper mold, and the lower mold is fixed on the surface of the bottom plate;

[0008] Demoulding mechanisms are provided on both sides of the lower mould. The centrifugal force generated by the rotation of the eccentric blocks drives the lower mould to vibrate, thereby achieving the demoulding effect.

[0009] Preferably, the demoulding mechanism includes a dual-axis motor and a pulley group. The dual-axis motor is fixed on the upper surface of the bottom plate, and pulley groups are fixed to the output ends of the dual-axis motor. Moreover, the front end of the pulley group is fixed to the rotating shaft.

[0010] Preferably, the inner ends of the rotating shafts are connected to both sides of the lower mould by bearings, and eccentric blocks are also fixed to the outer sides of the rotating shafts.

[0011] Preferably, cams are also fixed to the outer sides of the rotating shafts, and a pressing rod is provided below the cams.

[0012] Preferably, the lower end of the pressing rod extends into the air chamber. At the same time, the pressing rod is elastically and slidably connected to the bottom plate through a return spring, and both ends of the return spring are fixed to the bottom plate and the pressing rod respectively.

[0013] Preferably, the air chamber is opened inside the bottom plate, and the bottom end of the air chamber is connected to one end of an air pipe. At the same time, the other end of the air pipe extends out of the bottom plate and is connected to a shunt pipe.

[0014] Preferably, the shunt pipe is fixed on the upper surface of the bottom plate, and air jet nozzles are equally spaced on the outer side of the shunt pipe.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The headlight mould provided with a centrifugal demoulding structure not only realizes the demoulding effect through centrifugal force, thereby not damaging the shape of the headlight, reducing the probability of damage, and improving the production quality, but also can cool the headlight in the lower mould by air cooling, thereby reducing the temperature on the surface of the headlight and avoiding scalding due to excessive temperature during taking. The specific content is as follows:

[0016] (1) The dual-axis motor drives the rotating shafts to rotate together through the pulley group. Through the rotation of the rotating shafts, the eccentric blocks fixed to their outer sides are driven to rotate together, thereby generating centrifugal force and driving the lower mould to vibrate, and further realizing the demoulding effect through centrifugal force, thereby not damaging the shape of the headlight, reducing the probability of damage, and improving the production quality;

[0017] Furthermore, by providing two groups of eccentric blocks, sufficient centrifugal force is obtained, thereby achieving a better demoulding effect and avoiding the problem of inability to demould due to insufficient vibration;

[0018] Through the rotation of the cam, when it rotates to a certain angle, it will squeeze the pressure rod, causing the pressure rod to slide into the air chamber under force, thereby squeezing the air in the air chamber into the air delivery pipe. Then, it enters the shunt pipe through the air delivery pipe and is finally shunted to the jet head and ejected, so as to cool the headlights in the lower mold by air cooling, thereby reducing the surface temperature of the headlights and avoiding scalding due to excessive temperature when taking them;

[0019] At the same time, when the cam rotates to not contact the pressure rod, the pressure rod can be reset by the elastic force of the return spring, causing the return spring to drive the pressure rod to rise, which is convenient for reuse;

[0020] Furthermore, when the return spring drives the pressure rod to rise, the air chamber is replenished with air through the air replenishing port, so that the air chamber is filled with air again for reuse, thereby achieving the effect of cyclic air blowing, and there is no need for a separate power mechanism to operate, saving the device cost.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Please refer to Figures 1 - 6 , the present utility model provides the following technical solutions:

[0030] Embodiment 1: To solve the problem in the prior art that the demolding method easily damages the shape of the molded vehicle lamp, thereby causing damage to the vehicle lamp and affecting the production quality. Therefore, the following solution is disclosed, including a bottom plate 1 and a top plate 2 arranged above the bottom plate 1, and the top plate 2 and the bottom plate 1 are connected by vertical rods; further including: a cylinder 3 is fixed on the upper surface of the top plate 2, and the lower end of the cylinder 3 penetrates the top plate 2 and is fixed to the upper mold, and a lower mold is arranged below the upper mold, and the lower mold is fixed on the surface of the bottom plate 1; demolding mechanisms are arranged on both sides of the lower mold, and the vibration of the lower mold is driven by the centrifugal force generated by the rotation of the eccentric block 7 to achieve the demolding effect. The demolding mechanism includes a double-shaft motor 4 and a pulley group 5. Among them, the double-shaft motor 4 is fixed on the upper surface of the bottom plate 1, and pulley groups 5 are fixed to the output ends of the double-shaft motor 4, and the front ends of the pulley groups 5 are fixed to a rotating shaft 6. The inner ends of the rotating shafts 6 are connected to both sides of the lower mold by bearings, and eccentric blocks 7 are also fixed to the outer sides of the rotating shafts 6.

[0031] First, the mold drives the upper mold and the lower mold to fit together through the cylinder 3 to complete the injection molding of the vehicle lamp. After the molding is completed, the upper mold can be driven by the cylinder 3 to reset. At this time, the double-shaft motor 4 can be started, and the pulley group 5 is driven to rotate through the double-shaft motor 4. Through the rotation of the pulley group 5, the rotating shaft 6 is driven to rotate together. Through the rotation of the rotating shaft 6, the eccentric block 7 fixed to its outer side is driven to rotate together. Through the rotation of the eccentric block 7, its centrifugal force is generated and the lower mold is driven to vibrate, thereby achieving the demolding effect through centrifugal force, so as not to damage the shape of the vehicle lamp, reduce the probability of damage, improve the production quality, and two groups of eccentric blocks 7 are provided, so that it has sufficient centrifugal force to achieve a better demolding effect.

[0032] Embodiment 2: On the basis of Embodiment 1, a new technical solution is added to realize air-cooling the vehicle lamp in the lower mold, thereby reducing the temperature on the surface of the vehicle lamp and avoiding scalding due to excessive temperature during taking. Specifically refer to Figures 4 - 6 , the lower end of the pressure rod 9 extends into the air chamber 11. At the same time, the pressure rod 9 is elastically slidably connected to the bottom plate 1 through a return spring 10, and both ends of the return spring 10 are fixed to the bottom plate 1 and the pressure rod 9 respectively.

[0033] Meanwhile, while the rotating shaft 6 rotates, it will also drive the cam 8 to rotate together. Through the rotation of the cam 8, when it rotates to a certain angle, it will squeeze the pressure rod 9, so that the pressure rod 9 slides into the air chamber 11 under force, and then the air in the air chamber 11 is squeezed into the air delivery pipe 12. Subsequently, it enters the shunt pipe 13 from the air delivery pipe 12, and finally is shunted by the shunt pipe 13 and ejected from the jet head 14, so as to cool the vehicle lamp in the lower mold by air cooling, thereby reducing the temperature on the surface of the vehicle lamp and avoiding scalding due to excessive temperature when taking it.
