Abstract

The invention discloses an automobile bumper mould facilitating demoulding. The automobile bumper mould comprises a mould body, a forming mould cover, a knockout device and a demoulding seat, and both the bottoms of the two side ends of the forming mould cover are fixedly connected with sliding blocks; and the forming mould cover is internally provided with a cavity, and the knockout device is composed of a mould ejection block and tightening devices. According to the automobile bumper mould facilitating demoulding, the forming function is provided for the overall appearance of a bumper through the forming mould cover, and buffer plates are compressed downwards through the forming mould cover in a sliding structure in the mould punching process, so that the forming mould cover is moved downwards overall; meanwhile, tension is generated through one ends of the springs in the tightening devices, and the knockout device is moved downwards overall; since the downward movement is delayed, the primary mould ejection function is achieved at the moment of mould punching; when the springs are reset, and thrust force is generated, so that ejector pins on the top of the mould ejection block penetrate through slots in the appearance of the bumper, and the secondary mould ejection function is achieved; and the high efficiency demoulding function is achieved overall.

Example Embodiment

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0024] See Figure 1-4 , The present invention provides a technical solution: an automobile bumper mold that is convenient for lower molds, comprising a mold body 1, a forming mold cover 2, a mold ejection device 3, and a lower mold base 4, and the mold body 1 consists of a forming mold cover 2. , The mold ejection device 3 and the lower mold base 4, the bottom of the two sides of the molding die cover 2 are fixedly connected with the sliding block 5, and the interior of the molding die cover 2 is provided with a cavity 6 provided by the molding die cover 2. For the molding function of the overall appearance of the bumper, the external punching equipment drives the upper mold to impact downward to contact the molding die cover 2 to realize the punching function. The mold ejection device 3 is composed of a top module 7 and a tightening device 8. The top module 7 is placed in the cavity 6, and the top module 7 makes the bottom end actively contact with the inner side of the bottom end surface of the molding die cover 2. One end of the tightening device 8 passes through the through hole opened at the bottom end of the molding die cover 2 and the top The bottom end of the module 7 is fixedly connected, and the other end of the tightening device 7 is fixedly connected to the bottom end of the connecting block 9. The middle of the tightening device 7 is provided with a spring 10, and the top of the tightening device 7 is fixedly provided with a stopper. Plate 11, one end of the spring 10 is fixedly connected to the bottom end of the baffle 11, and the other end of the spring 10 is fixedly connected to the inner end of the connecting block 9. The specific number of the tightening device 7 is four, which are evenly distributed in the forming The bottom end of the mold cover 2 and the tightening device 7 are placed in the cavity of the connecting block 9. The top end of the connecting block 9 is fixedly connected to the bottom end of the molding module 2, and the connecting block 9 pulls down the tightening device 8 One end of the spring 10 generates a pulling force, and the mold ejection device 3 moves downward as a whole. However, due to the delay in the downward movement, a preliminary ejection function is generated at the moment of the punching. When the spring 10 returns to its position, a thrust is generated to make the ejection of the top module 7 The pin 18 passes through the groove on the appearance of the bumper to realize the secondary top mold function. The bottom end of the two sliding blocks 5 is in active contact with the top surface of the buffer plate 12, and the side surface of the sliding block 5 is fixed to the sliding block. The block is slidably connected to the slide rails on the side of the support block 13 fixed on both sides of the top of the lower mold base 4, and the bottom ends of the support block 13 and the buffer plate 12 are fixedly connected to the top of the lower mold base 4, and the molding process is performed The mold cover 2 compresses the buffer plate 12 downwards under the sliding structure of the sliding blocks 5 and the supporting blocks 13 at both ends, so that the forming mold cover 2 moves downward as a whole. The buffer plate 12 is provided with a cavity and a rebound device 14 The upper end is fixedly connected with the cavity wall, the spring 10 in the rebound device 14 pushes the buffer plate 12 to reset, and the forming mold cover 2 returns to the original position with a certain restoring force, thus achieving a high-efficiency lower mold function as a whole. A cavity 15 is opened in the middle of the lower mold base 4, and the cavity wall of the cavity 15 is composed of the side surface of the bearing block 16. A cavity 17 is opened in the middle of the top end of the bearing block 16, and the resilience device 14 is placed in the cavity 17 as a whole, the lower end of the rebound device 14 is fixedly connected inside the bearing block 16, and the middle of the rebound device 14 is provided with a spring 10, and both ends of the spring 10 are respectively connected to the bottom end surface of the buffer plate 12 It is movably connected to the top surface of the load-bearing block 15. The top end of the top module 7 is uniformly fixed with four top pins 18, and the top pins 18 correspond to the positions of the grooves on the top surface of the molding die cover 2. The connecting block 9 is integral Set In the bearing cavity 15.
[0025] Working principle: The automobile bumper mold that is convenient for the lower mold of the present invention provides the molding function of the overall appearance of the bumper through the molding die cover 2. The external punching equipment drives the upper mold to impact downward and contact the molding die cover 2 to realize the punching function. In the process, the forming mold cover 2 compresses the buffer plate 12 downward under the sliding structure of the sliding blocks 5 and the supporting block 13 at both ends, so that the forming mold cover 2 moves downward as a whole, and at the same time, the connecting block 9 pulls down the tightening device 8 At one end of the spring 10, a pulling force is generated, and the ejection device 3 moves downward as a whole. However, due to the delay in the downward movement, a preliminary top mold function is generated at the moment of the punching. When the spring 10 returns to its position, a thrust is generated to make the top of the top module 7 The ejector pin 18 passes through the groove on the appearance of the bumper to realize the secondary ejection function. Then the spring 10 in the rebound device 14 pushes the buffer plate 12 to reset, and the molding die cover 2 returns to the original position with a certain degree of recovery. Power, the overall high-efficiency die function is realized.
[0026] For those skilled in the art, it is obvious that the present invention is not limited to the details of the foregoing exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended to fall within the claims.
