Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold for processing a car dashboard mounting bracket. Background Technology

[0002] The dashboard mounting bracket is one of the important components of a car. Its workmanship and structural performance have a significant impact on the overall quality of the car. Moreover, in order to control costs, it is generally mass-produced by injection molding.

[0003] A search revealed that utility model patent CN214417458U discloses an automotive instrument bracket mold, comprising a lower mold base, an upper mold base, and a fixing component. The upper mold is fixedly mounted on the bottom of the upper mold base, and shock-absorbing rods are fixedly connected to both sides of the bottom of the upper mold. A positioning groove is fixedly connected to the top of the lower mold base, and the lower mold is embedded within the positioning groove. Shock-absorbing grooves are formed on both sides of the top of the lower mold, and shock-absorbing components are installed within these grooves. Fixing grooves are symmetrically formed on both sides of the lower mold. The fixing component is symmetrically arranged on both sides of the lower mold and includes a lifting block, a lead screw, and a connecting piece. The lead screw passes through the lifting block, and its bottom end is rotatably connected to the lower mold base via a bearing. A rotating disc is fixedly connected to the top end of the lead screw.

[0007] Preferably, one end of the first spring is fixedly connected to the guide block, and the other end of the first spring is fixedly connected to the inner surface of the locking block. By providing the first spring, the elastic force can be applied to the inclined seat through the guide block, thus assisting in its reset function.

[0008] Preferably, a pad and an oil-retaining sponge are slidably connected inside the guide block, with the pad and sponge in contact with each other. A sliding pin is fixedly connected to the bottom of the pad, and the end of the sliding pin abuts against the inner surface of the locking block. A protrusion is fixedly connected to the bottom inner side of the locking block, and the position of the protrusion corresponds to the end of the sliding pin. An oil outlet hole is provided inside the guide block, and the position of the oil outlet hole corresponds to both the oil-retaining sponge and the guide rod. The sliding pin, subjected to the reaction force of the protrusion, can squeeze the oil-retaining sponge through the pad, thereby releasing the lubricating oil.

[0009] Preferably, a sealing ring is embedded in the side of the pad, and the sealing ring is slidably connected to the inner surface of the guide block. The sealing ring provides a certain degree of sealing between the pad and the guide block.

[0010] Preferably, a sliding sleeve is fixedly connected to the bottom of the guide block, and a ball bearing is provided on the inner ring wall of the sliding sleeve. The sliding pin passes through the sliding sleeve and is slidably connected to the ball bearing. The sliding sleeve and the ball bearing assist in the sliding of the sliding pin under force.

[0011] Preferably, a guide sleeve is fixedly connected to the inner bottom of the guide block, a guide pin is slidably connected to the inner side of the guide sleeve, the top of the guide pin is fixedly connected to the pad block, and a second spring is provided on the inner side of the guide sleeve. One end of the second spring is fixedly connected to the guide pin, and the other end of the second spring is fixedly connected to the inner surface of the guide sleeve. The guide pin and guide sleeve provide force guidance for the pad block, while the second spring assists in the pad block's repositioning.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a locking block on the side of the lower mold and a locking sleeve on the side of the upper mold, with an ejector rod inside the locking sleeve. An inclined block that elastically expands and contracts via a guide block, guide rod, and spring is then provided on the locking block. When the upper and lower molds are closed, the ejector rod applies a pressing force to the inclined block, causing it to move laterally and fit against the sides of the upper and lower molds. This ensures sufficient accuracy during mold closing and prevents damage to the mold.

[0014] 2. This utility model features a guide block with a spring-supported pad and an oil-storing sponge on it to store a certain amount of lubricating oil. Additionally, a sliding pin extending from the guide block is located at the bottom of the pad. As the guide block moves, the sliding pin is subjected to the reaction force of a protrusion within the locking block, which compresses the oil-storing sponge and releases the lubricating oil. This lubricates the connection between the guide rod and the guide block, reducing wear on both and making it suitable for continuous use. Attached Figure Description
