Description

The counter forming machine prevent the outer enlarging device of pressing mold

Technical field

The utility model relates to a kind of counter forming machine, particularly relate to a kind of prevent module rock to shorten the typing activity duration the counter forming machine prevent the outer enlarging device of pressing mold.

Background technology

Referring to Fig. 1; counter forming machine in the past mainly comprises a shoe last mechanism 1 and a press moulding mechanism 2; this shoe last mechanism 1 comprises and moves a bar 101; one is installed in shoe last 102 and two clamping pieces 103 that are movably arranged on shoe last 102 dual-side places of mobile seat bar 101 upper ends; this press moulding mechanism 2 comprises the operating bar 201 of telescopic moving up and down; one connects the bracing frame 202 that is located at operating bar 201 lower ends; two connecting rods 203 that are articulated in bracing frame 202 both sides lower ends respectively; one is arranged on shell fragment 204 and that bracing frame place, 202 below and two ends and two connecting rods 203 be articulated is sticked and is attached to the inverted U-shaped pressing mold piece 205 at place, shell fragment 204 belows; this pressing mold piece 205 is slightly to be inverted U-shaped shape and can be along with shell fragment 204 distortion; in the middle of its below the place form one just with shoe last 102 opening opposing (I); when the counter forming machine will be finalized the design operation; the user at first places a workpiece (not shown) on shoe last 102; then operate shoe last mechanism 1 and press moulding mechanism 2 and move to relative position up and down; then allowing operating bar 201 drive whole press moulding mechanism 2 moves down; the opening of pressing mold piece 205 (I) can be inserted in matched moulds by corresponding shoe last 102; this moment, bracing frame 202 can be to these pressing mold piece 205 dual-side side pressures by two connecting rods 203; make pressing mold piece 205 medial surfaces and shoe last 102 jointly to the workpiece pressing; so just can finish the typing operation of counter, as shown in Figure 2.

Above-mentioned counter forming machine can be finished the typing operation of general counter really; but having its shortcoming to need badly on yet it uses will improve; the counter forming machine was after press moulding mechanism 2 was finished the typing operation in the past; it is up mobile and separate with this shoe last mechanism 1 that operating bar 201 just can drive whole press moulding mechanism 2; this moment, pressing mold piece 205 both sides no longer were subjected to side pressure; elastic force by this shell fragment 204; can allow pressing mold piece 205 both sides expand outward and strut this opening I; return to the state of Fig. 1; because pressing mold piece 205 is to be connected with bracing frame 202 in the pivot joint mode by two connecting rods 203; shell fragment 204 extends out and can affect two connecting rod 203 pivots pendulum and cause whole pressing mold piece 205 ceaselessly to rock; this can allow the opening (I) of pressing mold piece 205 can't aim at shoe last 102 easily; if it is quite serious that pressing mold piece 205 rocks situation; after the user can only wait for a period of time and allow pressing mold piece 205 shaking degree calm down a little; aim at the action of matched moulds again; so can cause the time of whole typing operation to spin out; reduction work production efficiency; and this pressing mold piece 205 carries out matched moulds with shoe last 102 under the inaccurate situation of contraposition, also can cause harmful effect to the Forming Quality of workpiece.

Summary of the invention

The utility model purpose is to provide a kind of module that prevents to rock to make things convenient for contraposition, can effectively shorten whereby the typing activity duration the counter forming machine prevent the outer enlarging device of pressing mold.

The utility model provides a kind of enlarging device outside the pressing mold that prevents of counter forming machine, comprise a board unit, at least one shoe last unit and at least one pressing mold unit, wherein: this board unit comprises a board and a framework that is arranged on place, board top, defines in the middle of this framework and the board and forms an operating space; This shoe last unit comprises that is arranged on first travel mechanism and a shoe last that is arranged on first travel mechanism's upper end that can enter on the board in the operating space; This pressing mold unit is arranged on the framework and is relative shape up and down with the shoe last unit, comprise that is arranged on second travel mechanism that can move along the vertical direction on the framework, one meets one in the side pressure mechanism that is located at second travel mechanism's lower end and connects and be located at side pressure mechanism below place and the inverted U-shaped module to should shoe last carrying out pressing, elastic mechanism and two detent mechanisms that are arranged on this module and the outer expansionary force of module dual-side generation can be provided, this detent mechanism connects respectively and is located at side pressure mechanism two outer side edges places, and each detent mechanism comprises that one is installed in extension rod in the side pressure mechanism and one and is located at the extension rod lower end and can keeps off and support module and support stopping bar with what restriction extended out.

Counter forming machine described in the utility model prevent the outer enlarging device of pressing mold, but should support the modulation of stopping bar spiral shell whole its towards the module extension elongation be arranged on the extension rod.

Counter forming machine described in the utility model prevent the outer enlarging device of pressing mold, this elastic mechanism also comprises one and is movably arranged on place in the middle of the bracing frame and compress part and of press contacts under the module top is set in and compresses the spring that elastic-restoring force is provided on the part.

The beneficial effects of the utility model are: utilize and at bracing frame dual-side place two detent mechanisms are set, two detent mechanisms are subjected to that elastic mechanism suppresses and when extending out in module, can rock to prevent from extending out the module block, reach the effect that shortens the typing activity duration whereby.
