Description

Technical Field

[0001] This utility model relates to the field of mold production equipment technology, specifically to a self-calibrating automotive bracket mold guiding and closing mechanism. Background Technology

[0002] In automobile production, a large number of brackets made of metal and resin materials are required. The production precision and strength of these brackets will have a certain impact on the performance, stability and aesthetics of the car. In the mold closing process of traditional bracket molds, alignment mainly relies on manual adjustment or simple guiding mechanisms. Manual adjustment depends on the operator's experience, which makes it difficult to ensure the consistency of mold closing precision each time. Moreover, the adjustment process is time-consuming and labor-intensive, affecting production efficiency. After long-term use, traditional fixed guiding mechanisms are prone to wear, which can lead to increased mating clearance, affecting mold closing precision, and even causing mold damage and shortening the mold's service life. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed, self-calibrating automotive bracket mold guiding and closing mechanism that can solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: It includes an upper mold base and a lower mold base. An upper mold is installed below the upper mold base via multiple connecting bolts, and a lower mold is installed on the lower mold base via multiple connecting bolts. Multiple sets of guide structures are provided between the upper mold base and the lower mold. The guide structures include alignment holes opened on the lower mold. An installation groove is opened above the alignment hole. A funnel-shaped fixing member is provided in the installation groove. Several balls are provided on the inner surface of the fixing member. The inner diameter of the bottom end of the fixing member is the same as the inner diameter of the alignment hole. A conical alignment seat is provided below the upper mold base. An alignment rod is connected below the alignment seat. The diameter of the alignment rod is the same as the inner diameter of the alignment hole.

[0005] Preferably, the bottom of the mounting slot has a stepped groove extending outwards, and the bottom of the fastener has a protruding stepped portion that fits into the stepped groove. The hole in the stepped portion is flush with the alignment hole.

[0006] Preferably, the upper mold, the alignment seat, and the alignment rod are an integral structure.

[0007] Preferably, the bottom edge of the alignment rod has a chamfered surface, and the inclination angle of the chamfered surface matches the angle of the inner inclined surface of the fixing member.

[0008] Preferably, the lower mold has a fixing groove at the opening of the mounting slot, and multiple bolt holes are opened in the fixing groove. The top of the fixing part is connected to an annular mounting part, which is located in the fixing groove and is installed by fixing bolts and bolt holes.

[0009] The beneficial effects of this utility model after adopting the above structure are:

[0010] 1. This utility model is designed with a positioning seat, a positioning rod, a positioning hole, and a fixing component, so that the positioning rod can automatically guide the mold during mold closing, ensuring mold calibration and preventing deviation during mold closing that would lead to a decrease in production quality. At the same time, the design incorporates ball bearings, using rolling friction to replace hard friction, which significantly reduces wear.

[0011] 2. This utility model features an integrated upper mold, alignment seat, and alignment rod design, which enhances the overall structure, improves the stability and durability of the mold, and because the mold steel used is of high hardness, while the fixing parts and balls are made of mass-produced stainless steel with relatively lower hardness, wear will mainly occur on the surface of the balls and fixing parts during use, thus protecting the alignment seat and alignment rod.

[0012] 3. The fastener in this utility model is designed to be detachable, and can be quickly disassembled and assembled with bolts to ensure its performance. At the same time, since the balls are exposed, maintenance is convenient and lubricant can be added directly from the outside. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-6 As shown, it includes an upper mold base 1 and a lower mold base 2. An upper mold 3 is installed below the upper mold base 1 by multiple connecting bolts 5, and a lower mold 4 is installed on the lower mold base 2 by multiple connecting bolts 5. Multiple sets of guide structures are provided between the upper mold base 1 and the lower mold 4. The guide structure includes an alignment hole 6 opened on the lower mold 4. An installation groove 7 is opened above the alignment hole 6. A funnel-shaped fixing member 11 is provided in the installation groove 7. Several balls 13 are provided on the inner surface of the fixing member 11. The balls 13 are evenly distributed. The fixing member 11 and the balls 13 are made of stainless steel to ensure that the alignment rod 15 can slide smoothly when moving and reduce friction. The inner diameter of the bottom end of the fixing member 11 is the same as the inner diameter of the alignment hole 6 to ensure that the alignment rod 15 can be accurately inserted into the alignment hole 6.

[0023] Below the upper mold base 1 is a tapered alignment seat 14, and below the alignment seat 14 is an alignment rod 15. The diameter of the alignment rod 15 is the same as the inner diameter of the alignment hole 6, ensuring that the alignment rod 15 can smoothly enter the alignment hole 6 and achieve precise alignment. At the bottom of the mounting slot 7, a stepped groove 8 is opened outward. The bottom end of the fixing member 11 is provided with a protruding stepped part, which is stuck in the stepped groove 8. The hole in the stepped part is flush with the alignment hole 6, ensuring that the fixing member 11 is firmly installed in the mounting slot 7 and avoiding displacement during operation.

[0024] The upper mold 3, the alignment seat 14, and the alignment rod 15 are integrated into one structure. This design not only enhances the overall integrity of the structure but also improves the strength and durability of the alignment seat 14 and the alignment rod 15. Moreover, since the mold steel has a high hardness, while the fixing part 11 and the ball 13 are made of stainless steel with relatively low hardness, wear will mainly occur on the surface of the ball 13 and the fixing part 11 during use, thus protecting the alignment seat 14 and the alignment rod 15. The bottom edge of the alignment rod 15 has a chamfered surface 16, and the inclination angle of the chamfered surface 16 matches the angle of the inner inclined surface of the fixing part 11, making the alignment rod 15 enter the fixing part 11 more smoothly and reducing the resistance during the alignment process.

[0025] A fixing groove 9 is opened at the opening of the mounting slot 7 on the lower mold 4. Multiple bolt holes 10 are opened in the fixing groove 9. The top of the fixing part 11 is connected to an annular mounting part. The mounting part is located in the fixing groove 9 and is installed by fixing bolts 12 and bolt holes 10 to ensure that the connection between the fixing part 11 and the lower mold 4 is firm and reliable, and to prevent loosening or falling off during operation.

[0026] During the initial installation and use, the upper mold 3 and lower mold 4 will be calibrated. Figure 3 , Figure 5 As shown, when the upper mold 3 and the lower mold 4 approach each other, the alignment rod 15 is aligned with the alignment hole 6, and as the mold moves, the alignment rod 15 is inserted into the alignment hole 6 to guide and limit the mold. The surface of the alignment seat 14 is in contact with the steel ball to enhance the support force and prevent the lateral force caused by vibration during use from being applied to the alignment rod 15.

[0027] In subsequent use, such as Figure 6 As shown, due to mold deformation or deformation and offset of the mounting mechanism, the alignment rod 15 and the alignment hole 6 are offset. During operation, the alignment rod 15 will press down onto the inclined surface of the fixing part 11, and the chamfered surface 16 will first press onto the ball 13, and then slide obliquely on the ball 13, driving the upper mold 3 to slide to the side until the alignment rod 15 is aligned with the alignment hole 6 and enters until it is inserted into the alignment hole 6.

[0028] When the alignment rod 15 initially reaches the hole, the edge may rub against the edge where the top of the inner hole of the fixing part 11 connects with the inclined surface. Therefore, there will be some wear after long-term use. The wear during use will be concentrated on the ball 13 and the edge where the top of the inner hole of the fixing part 11 connects with the inclined surface. After a period of use, the operator can remove the fixing bolt 12 and replace the fixing part 11.

[0029] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
