Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a main body structure of a mother mold. Background Art

[0002] The female mold refers to the concave part of the entire mold, which is the cavity, also known as the front mold or the female mold, and the corresponding convex part is called the core, also known as the back mold or the male mold. The cavity and the core of the mold are combined, and the gap in the middle is the product.

[0003] The current female mold body needs to be used in conjunction with the male mold during use. When the two are closing the mold, there is no buffer structure, such as a female mold inclined slider structure disclosed in announcement number CN104708771B. The male mold and the female mold are fitted on a flat surface. Once the closing speed is too fast, it is easy to cause a collision, thereby causing damage to the female mold and the male mold due to the collision. The current solution is to achieve slow closing through high-precision control equipment, but it still cannot completely guarantee that there will be no accidental collision, so there is room for improvement during use. Utility Model Content

[0004] The utility model aims to provide a main structure of a female mold to solve the problem that the female mold proposed in the above background technology has no buffer structure, which may cause serious collision between the female mold and the male mold in the event of rapid closure due to an accident.

[0005] To achieve the above object, the utility model provides the following technical solution: a master mold main body structure, including a mold body, two ends of the mold body are provided with placement grooves, and a buffer component is arranged in the placement groove, and the buffer component includes:

[0006] The fitting piece has a top that protrudes outside the placement groove, and two ends that are slidably embedded in the placement groove. In use, the fitting piece will contact the male mold before the mold body. Rolling pieces are provided between the two ends of the fitting piece and the placement groove to reduce resistance during movement.

[0007] The adjusting member is arranged between the fitting member and the placement groove, and the fitting member cover is arranged outside the adjusting member. The adjusting member is used to adjust the position of the fitting member and ensure that the fitting member is always outside the placement groove when not under pressure.

[0008] Preferably, the fitting part includes a fitting frame movably arranged in the placement groove, a movable groove is opened at the side wall of the placement groove, and connecting columns are fixed at both ends of the fitting frame. The connecting columns are slidably inserted into the interior of the movable groove. Through the connection between the connecting columns and the movable groove, the fitting frame can be slidably slid, thereby ensuring that the fitting frame can move vertically and will not be moved horizontally.

[0009] Preferably, the rolling member is a ball, the ball portion protrudes to the inner side of the movable groove, and rolls with the side of the connecting column to reduce friction during operation. During installation, a hole needs to be opened in the inner wall of the movable groove, and then the ball is embedded in the hole. The welding point at the opening of the hole is then spot-welded, and the welding point should block the ball. The welding point is then separated from the ball to achieve positioning of the ball.

[0010] Preferably, the adjusting member is a spring, the bottom end of which is fixed on the inner bottom surface of the placement groove, and the top end of the spring is against the inner top surface of the fitting frame. When the male mold is pressed down, it will first contact the fitting frame. At this time, the fitting frame presses down the spring, and the elastic force generated by the spring through rebound offsets part of the pressure of the male mold descending, thereby achieving a buffering effect.

[0011] Preferably, a cavity is provided on the top surface of the mold body, and an inner mold is placed inside the cavity. In actual production, inner molds with different rotations can be replaced to achieve different types of processing.

[0012] Preferably, the front and rear surfaces of the mold body are provided with through holes connected to the cavity, the surface of the inner mold is provided with an insertion hole, and the through hole is penetrated by a columnar body which is inserted into the insertion hole, wherein the columnar body is not drawn in the figure, and the inner mold is limited by the columnar body.

[0013] Preferably, guide pillars are passed through the four corners of the mold body, and the guide pillars are connected to the male mold through the guide pillars, so that the vertical closing guidance of the male mold and the mold body is achieved.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The designed buffer component can provide buffer protection when the female mold and the male mold are fitted together to avoid damage caused by accidental rapid contact between the two. At the same time, the buffer component can be hidden on the female mold when the male mold and the female mold are closed, without causing any impact on normal processing. At the same time, the buffer component has low damping when moving up and down, so there will be no descent jamming phenomenon, and the overall stability of use is high. The design of the buffer component improves the shortcomings of the existing female mold main structure in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The top of the fitting protrudes to the outside of the placement groove 100b, and the two ends are slidably embedded in the inside of the placement groove 100b. In use, the fitting will contact the male mold before the mold body 100. Rolling members are arranged between the two ends of the fitting and the placement groove 100b to reduce the resistance during movement.

[0024] The adjusting member is arranged between the fitting member and the placement groove 100b, and the fitting member cover is arranged outside the adjusting member. The adjusting member is used to adjust the position of the fitting member and ensure that the fitting member is always outside the placement groove 100b when not under pressure.
