Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, the second hooking portion 21 is provided with a first slope 22 . The bushing 30 is provided with a protrusion 32 , and the protrusion 32 is provided with a second slope 31 adapted to the first slope 22 .

[0046] In this embodiment, the pressure F exerted by the bushing 30 on the second hooking portion 21 is decomposed into two relatively perpendicular forces through the cooperation of the first slope 22 and the second slope 31 . The first force is the force F1 perpendicular to the contact surface between the first hook 112 and the second hook 212, which increases the pressure on the contact surface between the first hook 112 and the second hook 212, that is, increases The friction force between the first hooking part 11 and the second hooking part 21 is increased, thereby improving the connection strength between the first hooking part 11 and the second hooking part 21, and a larger external force is required to make the seco...

Embodiment 2

[0054] Such as Figure 6 As shown, the second hooking portion 21 is provided with a first slope 22; the bushing 30 is also provided with a connection groove 33, and the groove wall of the connection groove 33 is provided with a second slope 31 matching the first slope 22. , the first hooking portion 11 and the second hooking portion 21 are located in the connecting groove 33 .

[0055] In this embodiment, the connecting groove 33 plays a protective role for the first hooking portion 11 and the second hooking portion 21, preventing the first hooking portion 11 and the second hooking portion 21 from slipping due to external force (such as impact). The occurrence of the situation, thereby reducing the probability of failure of the inclined top demoulding mechanism, improving the reliability of the use of the inclined top demoulding mechanism, and can smoothly release the casting 80 from the casting mold, greatly improving the production efficiency of the casting 80, reducing the ...

Embodiment 3

[0057] Such as Figure 7 As shown, the second hooking portion 21 is provided with a first mating surface 23 ; the bushing 30 is provided with a second mating surface 35 adapted to the first mating surface 23 .

[0058] In this embodiment, the bushing 30 is sleeved on the push rod 10 , and the bushing 30 presses against the second hooking portion 21 . The bushing 30 applies pressure to the second hooking portion 21, and the pressure applies the first mating surface 23 and the second mating surface 35; thereby improving the friction between the first mating surface 23 and the second mating surface 35, that is, improving The friction force between the first hooking part 11 and the second hooking part 21 is improved, and the connection strength between the first hooking part 11 and the second hooking part 21 is improved, and a relatively large external force is required to make the first hooking part 11 The hooking part 11 is separated from the second hooking part 21, that is, th...

Abstract

The invention provides an inclined ejection demoulding mechanism and a casting mold. The inclined ejection demoulding mechanism comprises an ejector rod, an inclined ejection part and a bushing, wherein one end of the ejector rod is provided with a first hooking part, the first hooking part comprises a first hooking groove and a first clamping hook, one end of the inclined ejection part is provided with a second hooking part, the second hooking part comprises a second hooking groove and a second clamping hook, the first clamping hook is clamped into the second hooking groove, the second clamping hook is clamped into the first hooking groove, the bushing is arranged on the ejector rod in a sleeving mode, and the bushing is pressed against the second hooking part. According to the inclined ejection demoulding mechanism, the bushing is pressed against the second hooking part, the second hooking part is pressed against the first hooking part, so that the pressure between the first clampinghook and the second clamping hook is increased, that is, the friction force between the first clamping hook and the second clamping hook is increased, the connection strength between the first clamping hook and the second clamping hook is improved, the probability that the first hooking part and the second hooking part slip off is reduced, furthermore, the use reliability of the inclined ejectiondemoulding mechanism is improved, and the market competitiveness of a product is increased.

Description

technical field [0001] The present application relates to the technical field of moulds, in particular, to an inclined top demoulding mechanism and a casting mold having the inclined top demoulding mechanism. Background technique [0002] The description of the background technology in this application belongs to the relevant technology related to this application, which is only used for illustration and to facilitate the understanding of the application content of this application, and should not be understood as that the applicant clearly believes or presumes that the applicant believes that this application was filed for the first time prior art on the filing date. [0003] In the production of cast products, it is often encountered that the side of the product is undercut, which requires an inclined roof structure on the demoulding mechanism to demould the product. In the related art, in order to ensure the strength of the inclined roof structure, a double-section incli...
