Embodiment Construction
[0015] Such as figure 1 As shown, the present invention provides a bumper demoulding straight top assembly, comprising a straight plug 6 and an insert 1, the rear of the insert 1 is covered with a spring 3;
[0016] The rear end surface of the insert 1 has an elastic block, and the front portion of the elastic block has a radially protruding portion 21 relative to the outer surface of the insert 1 and the rear portion 22 of the elastic block; step surface conflict;
[0017] The straight plug 6 has a stepped through hole capable of accommodating the insert 1, the spring 3 and the elastic block moving back and forth. The stepped through hole runs through the front surface and the rear end surface of the straight plug 6. The insert 1 and the spring 3 are located in the stepped through hole. The front end of the insert 1 has a groove 11, and the groove 11 is adapted to the protruding part of the product made by the mold;
[0018] The front part of the projectile block is located...

The invention provides a straight ejection component for demoulding a bumper. The straight ejection component comprises a straight ejection head and an embedding part, wherein a spring is sleeved on the back of the embedding part; the back end face of the embedding part is provided with an elastic block; step through holes in which the embedding part, the spring and the elastic block move forward and backward are formed in the straight ejection head; the embedding part and the spring are located in the step through holes; a profiled groove is formed in the front end face of the embedding part; the profiled groove is adaptive to a part which is protruded on a product manufactured by a mould; parts of the step through holes, which are located on the back of the protruded part, are provided with back limit step surfaces; when the elastic block pops out backwards, a back step surface of the protruded part props against the back limit step surfaces; when the spring is pressed till the back end face of the elastic block is aligned to the back end faces of the step through holes, a distance from the back step surface of the protruded part to the back limit step surfaces is adaptive to the depth of the profiled groove. The straight ejection component for demoulding the bumper has the beneficial effect that the problem of demoulding difficultly due to the great packaging force of a concave part during demoulding is solved.
Description
technical field [0001] The invention relates to a bumper demoulding straight top assembly. Background technique [0002] In the existing technology, there is a concave part on the mold. Due to the large clamping force during demoulding, it is easy to cause deformation and damage to the product. Taking the mold for making a bumper as an example, the BOSS column and U-shaped rubber are located on the straight top. After forming, due to the relatively deep position of the BOSS column and the U-shaped glue, under the action of the wrapping force, the product will still remain on the straight top and cannot be demolded after the straight top is ejected Contents of the invention [0003] The invention provides a bumper demoulding straight top assembly, which solves the problem of difficulty in demoulding due to the tightness of the inner concave part. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: b...
