Abstract

The utility model relates to a die, comprising a main buckling arm axially connected with an outer die plate and a fixed first locking piece. Elastic connection is formed between the main buckling arm and the first locking piece, the central part of the main buckling arm is axially connected with a side buckling arm extended to the first locking piece, and the other end of the outer die plate is fixedly provided with a second locking piece. The second locking piece approaches to the other end of the axial connecting position of the main buckling arm, and a contact surface between the main buckling arm and the second locking piece and the contact surface between the side buckling arm and the first locking piece are matched and clamped via a concave and convex hook bodies in order to fix the die plate on every layer via the locking between the main buckling arm and the second locking piece and between the side buckling arm and the first locking piece. The main buckling arm can be pressed by an elastic plate to release the clamp of the die plate on every layer and open the die.

Description

Die lock catch mechanism

The utility model relates to mould.Two layers of its latching device of mould of tool particularly with cope match-plate pattern.

Existing compression molding of moulding goods is after plastics are placed mould, mould is inserted the board stamping position again, and operations such as plastic foamed moulding, cooling back taking-up product are realized.This thermoforming way, because it is no longer mobile in whole technical process that mould is put the back, so the template of Xiang Lei only is subjected to single vertical effect to pressure about in the mould, can not produce the interlayer slip between each template, so can not establish latching device between each template with they mutual snap closes; But because whole hot-forming process is carried out in single position, production efficiency is lower, and energy resource consumption is also big.

For enhancing productivity, reduce cost, at present for bigger hot-forming product in batches generally adopt pressurization, heat, cooling, the demoulding form separately independently that operation formation continuous production line carries out, its advantage be can enhance productivity greatly, energy savings; But the problem of Chu Xianing is simultaneously: confessing one's crime the pressurization operation when later on each operation transmits when the mould that is equipped with product, each of mould layer template can produce relative storey displacement because of being subjected to the effect of horizontal unbalanced force simultaneously, thereby influences the quality of product.

Order of the present utility model is to provide a kind of Die lock catch mechanism that makes the template with two layers or more template mold can not produce interlayer slip in process of production in vain.

The utility model is to realize like this, Die lock catch mechanism, comprise: at be coupling a main button arm and set firmly one first lock dog of an outer template, between the main button arm arm body and first lock dog, formation elastic force connects, main button arm is slightly near central position, the side button arm that is coupling stretches to first lock dog, hold in other and to be installed with second lock dog on the outer template, this second lock dog closes on the end in addition that main button arm axle meets the place, respectively form the cooperation stopper of embossed area body in the abutment face of the main button arm and second lock dog, and also form the concavo-convex cooperation clip that colludes body in the abutment face that side button arm stretches to first lock dog.

Wherein, the mould outer template is cope match-plate pattern and lower bolster, folder is established middle template between cope match-plate pattern and lower bolster, the cope match-plate pattern side is provided with the mould screw, and on first lock dog, offer open-work, be provided with fixed screw in the open-work and lock the patrix screw, first lock dog is fixed on the cope match-plate pattern, and in the other axis body that is convexly equipped with of patrix screw, offer axis hole in main button arm one end, this axis hole wears axis body, makes main button arm axle be connected to cope match-plate pattern, and this master's button arm is inboard slightly near central position, protrude out a shank to the side, offer pin-and-hole in side button arm one end in addition, shank penetrates in the pin-and-hole, and side button and main button arm are coupling, in side button arm and holding in addition that main button arm is coupling, form latch, and this end is stretched to first lock dog, be concaved with chute in the first lock dog inner edge, side button arm is formed one of latch end, stretch in the chute, make latch collude card chute edge arm, form concavo-convex cooperation fastening of colluding body, on main button arm, offer a spring base hole, and on first lock dog, also offer a spring base hole, install spring between two spring base holes, main button arm be connected with the first lock dog elastic force.

Wherein, the lower bolster side of holding in addition that mould is provided with first lock dog is provided with the counterdie screw, and on second lock dog, offer open-work, be provided with solid screw in this open-work and lock the counterdie screw, second lock dog is locked on the lower bolster, and this second lock dog closes on the end in addition that main button arm axle meets the place, main button this end of arm is also sharp towards second lock dog formation button, and second lock dog is located with respect to the button point, forms sharp edge, form the button lip in sharp edge lower end, it is moving that the button point is pushed via the cunning with sharp edge, falls into the button lip, makes the abutment face of the main button arm and second lock dog respectively form the concavo-convex cooperation stopper that colludes body.

Wherein, the axis hole that main button arm one end is offered is embedded with a lining, wears axis body again.

Wherein, main button arm is inboard to be arranged with a chamber slightly near the position of central authorities, protrudes out shank to the side in chamber.

Wherein, side button arm and holding in addition that main button arm is coupling, the latch of formation is divided into first latch and second latch.

The utility model has the advantages that: because the setting of main button arm and second lock dog, side button arm and first lock dog, but snap close is fixed each layer template, make them can not produce mutual interlayer slip, and the elastic plate that utilizes spring is pressed the main arm of buckleing, discharge the clamping of each layer template, open mould, not only easy to operate, and can improve the quality of products.
