Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to technology of the present utility model The implication that the technical staff in domain is generally understood that is identical.It is simply in term used in the description of the present utility model herein The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include The arbitrary and all combination of one or more related Listed Items.

It is an a kind of preferred embodiment of back-off demolding structure 100 of the utility model to refer to Fig. 1, including a driving structure 1st, the demolding structure 3 of a connection piece 2 and one.

The driving structure 1 includes a drivig cylinder 11, a fixed mount 12 and a pipeline 13, and the drivig cylinder 11 is fixed In the fixed mount 12, the pipeline 13 is connected with the drivig cylinder 11, it is preferred that the drivig cylinder 11 be a cylinder or Oil hydraulic cylinder or electric cylinder, the drivig cylinder 11 include a piston rod 111.

The demolding structure 3 includes a first assembly 31, one second component 32, a guide 34 and two locating parts 35, a die cavity 33 is formed between the component 32 of first assembly 31 and second, and a product 200 is contained in the die cavity 33, described Second component 32 is fixed in the one end of two locating part 35, and the other end is contained in the first assembly 31, and described at least one is spacing Part 35 makes the component 32 of first assembly 31 and second separate a certain distance until being contradicted with two locating parts 35, concedes product Second component 32 is fixed in 200 demoulding locus, described one end of guide 34, and the other end is contained in the first assembly 31。

Preferably, the quantity of locating part 35 is 2-10, and the locating part 35 screws for match, and uniformly arrangement makes stress It is balanced.

Preferably, the locating part 35 includes a spring 351, and the spring 351 is located at the first assembly 31 and second Between component 32, the component 32 of first assembly 31 and second is avoided to be bonded tension, when the connector 2 pulls the first assembly Move directly the second component 32 when 31, the product 200 for making to be clipped between the component 32 of first assembly 31 and second is pulled.

The back-off demolding structure 100 is assembled, the fixed mount 12 is fixed on a template, and the drivig cylinder 11 is fixed on The fixed mount 12, the piston rod 111 are connected with the connector 2, and the connector 2 is connected with the first assembly 31, The product 200 is contained in the die cavity 33.

Using the back-off demolding structure 100, the drivig cylinder 11 drives the piston rod 111 to make the connector 2 The first assembly 31 is driven away from the second component 32 until the first assembly 31 contradicts with the locating part 35, merges out one Space is stripped, smoothly to allow product 200 to be stripped, while the back-off of product 200 is partially disengaged the first assembly 31, now connects Part 2 further pulls on the first assembly 31, and the first assembly 31 drives the locating part 35 so as to drive described second group Part 32, the back-off part of product 200 is set to pull out the second component 32, now product 200 can typically be bent, and thimble 4 ejects, and makes product The 200 smoothly demouldings.

Using the performance of the flexible deformation of plastic cement, one-off is that first assembly 31 first exits a space stroke, is conceded Deformation space position, the second component 32 is pulled to draw product 200 to deform with first assembly 31 afterwards, production mouth 200, which is pulled out inner side, to fall Button, then thimble 4 makees ejection action, and product 200 is ejected, and reduces oblique top on the inside of traditional dies, and mould structure becomes simple, Processing capacity, workload greatly reduce, and improve production efficiency.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims Within the scope of.
