Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a dual-channel automotive taillight housing injection mold. Background Technology

[0002] Automotive lights are various traffic lights installed on automobiles to ensure safe driving. They are divided into two categories: headlights and signal lights. From 1905 to 1912, to solve the problem of road illumination, spotlight-type acetylene headlights were first installed, along with a kerosene lamp for the rear license plate. From 1945 to 1947, the minimum required external lighting fixtures were finalized. Qualified automotive lights should meet the corresponding luminous intensity, chromaticity, and basic environmental testing standards. With social development, most automotive taillight housings are now produced using injection molding, which requires the use of injection molds.

[0003] Existing technologies, such as the utility model patent with publication number CN220331904U, disclose an injection mold for an automotive taillight housing. This mold includes a fixed mold, a movable mold on the top surface of the fixed mold, and first water channels inside both the fixed and movable molds. A punch is located within the fixed mold, and a second water channel communicating with the first water channel within the punch is located within the punch. The second water channel is serpentinely distributed within the punch and communicates with the first water channel via a connector, which is slidably connected to the fixed mold. This utility model, by providing a second water channel within the punch and using a connector to connect the second water channel to the first water channel, allows cooling water to directly cool the punch, improving the solidification efficiency of the molded parts within the mold.

[0004] Currently, most injection molds use multiple pipes to transport cooling water. During operation, two water supply pumps are required, which increases the cost of using the mold, the probability of equipment maintenance, and the economic losses of the producer. This is also detrimental to production operations, so improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing technology where most injection molds use multiple pipes to transport cooling water, requiring two water supply pumps during use, which increases the cost of using the mold, the probability of equipment maintenance, and the economic losses of producers, and is not conducive to production operations. Therefore, a dual-channel automotive taillight housing injection mold is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dual-channel automotive taillight housing injection mold, comprising a base plate, a lower mold mounted on the upper surface of the base plate, a guide rod fixedly connected to the upper surface of the lower mold, an upper mold slidably connected to the guide rod, the upper mold being located above the lower mold, a top plate fixedly connected to the upper surface of the upper mold, an injection port fixedly connected to the upper surface of the top plate, and a heat dissipation device provided on one side of the base plate, the heat dissipation device comprising a water guide pipe, one end of the water guide pipe being fixedly connected to one side of the upper mold. The other end of the water guide pipe is fixedly connected to one side of the lower mold. A water outlet pipe is fixedly connected to one side of the upper mold, and a water inlet pipe is fixedly connected to one side of the lower mold. A sliding groove is provided on the surface of the base plate. A support rod is slidably connected to the inner wall of the sliding groove. A collar is fixedly connected to one end of the support rod. A reset device is provided on the surface of the lower mold. This solution integrates the equipment, requiring only one pump body to achieve heat dissipation for the upper and lower molds, reducing the operating cost of the equipment, lowering the probability of equipment maintenance, reducing economic losses for producers, and facilitating production operations.

[0007] Preferably, both the upper and lower molds are equipped with water channels inside. The water outlet pipe is connected to the water guide pipe through the water channel, and the water inlet pipe is connected to the water guide pipe through the water channel. In use, the water inlet and outlet pipes are connected to an external pipeline, and water is supplied through the water inlet pipe. The water flows from the water inlet pipe into the water channel of the upper mold, and from the water guide pipe into the water channel of the lower mold, and finally is discharged from the water outlet pipe, thereby achieving heat absorption and transfer and realizing heat dissipation.

[0008] Preferably, there are two of each of the sliding groove, support rod, and collar, and the two sliding grooves, support rods, and collars are arranged symmetrically. The two collars are respectively fitted onto the water guide pipe and the water outlet pipe to facilitate support for the water guide pipe and the water outlet pipe.

[0009] Preferably, the longitudinal section of the support rod is L-shaped, and the corners of the support rod are rounded to improve the aesthetics of the equipment.

[0010] Preferably, a positioning rod is fixedly connected to the upper surface of the base plate, and an installation sleeve is fixedly connected to the upper surface of the positioning rod. One end of the water inlet pipe and the water outlet pipe are both inserted into the installation sleeve, which facilitates the normal use of the equipment.

[0011] Preferably, the reset device includes a support rod, which is fixedly connected to the surface of the lower mold. A connecting plate is fixedly connected to one side of the two support rods that are close to each other. The connecting plate is sleeved on the support rod and slides on the surface of the support rod. A spring is sleeved on the support rod, and both ends of the spring are fixedly connected to the lower mold and the connecting plate, respectively. A protrusion is fixedly connected to the end of the support rod away from the lower mold. When discharging, the upper mold moves upward, and the water guide pipe and the water outlet pipe are driven by force to move the collar. The collar then drives the support rod to insert into the slide groove. The connecting plate squeezes the spring, and the spring deforms under force. After the discharging operation is completed, the upper mold resets, and the spring pushes the connecting plate, support rod and collar to reset.

[0012] Preferably, there are two support rods, which are symmetrically arranged to ensure stable displacement of the connecting plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, during use, an external pipeline is connected through an inlet pipe and an outlet pipe. Water is supplied through the inlet pipe, flowing into the water channel of the upper mold and then into the water channel of the lower mold through the guide pipe, finally exiting through the outlet pipe. This achieves heat absorption and transfer, realizing heat dissipation. During material discharge, the upper mold moves upward, and the guide pipe and outlet pipe are driven by force to move the collar. The collar then drives the support rod to insert into the slide groove, and the connecting plate squeezes the spring. The spring is deformed by force. After the material discharge operation is completed, the upper mold resets, and the spring pushes the connecting plate, support rod, and collar to reset. This solution integrates the equipment, requiring only one pump body to achieve heat dissipation for the upper and lower molds, reducing equipment operating costs, lowering the probability of equipment maintenance, reducing economic losses for producers, and facilitating production operations.

This solution integrates the equipment, requiring only one pump body to achieve heat dissipation for the upper mold 3 and the lower mold 2, reducing the operating cost of the equipment, reducing the probability of equipment maintenance, reducing the economic losses of producers, and facilitating production operations.

[0023] In this embodiment, both the upper mold 3 and the lower mold 2 are equipped with water channels. The water outlet pipe 72 is connected to the water guide pipe 71 through the water channel, and the water inlet pipe 75 is connected to the water guide pipe 71 through the water channel.
