Abstract
The utility model provides a secondary automatic demoulding mechanism of a buckle-down mould. The secondary automatic demoulding mechanism comprises a front template, a front mould fixing plate, a rear template, a rear mould fixing plate and a mould foot. The front template is mounted on the front mould fixing plate, and the rear template is connected with the mould foot and mounted on the rear mould fixing plate. An ejector rod is arranged on the rear mould fixing plate. A face needle plate and a bottom needle plate are arranged between the interior of the mould foot and the fixing plates, a return pin is arranged on the face needle plate, and the bottom needle plate is connected with the ejector rod, so that the face needle plate and the bottom needle plate can carry out oriented stable motions through the ejector rod and the return pin. A mould core cavity is formed between the front template and the rear template. The secondary automatic demoulding mechanism is characterized in that another bottom needle plate is added between the rear mould fixing plate and the bottom needle plate, and the other bottom needle plate is larger than the bottom needle plate. An oblique support is mounted on the other bottom needle plate, and the other end of the oblique support is connected with the mould core cavity. The interior of the mould foot is provided with a limiting step position corresponding to the other bottom needle plate. According to the structure of the secondary automatic demoulding mechanism, one time demoulding motion can simultaneously achieve a demoulding mode of twice ejection, forming time of products is shortened, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of injection mold structure, a kind of back-off mould particularly, a kind of back-off demoulding mechanism that can carry out the secondary automatic demoulding.
Background technology
The production of plastic cement products all is to adopt mould to carry out injection molded.The structure of mould directly affects the quality of product and the efficient of production.
When the plastic sidewall has logical sky, depression, boss or back-off shape, generally all need to carry out the secondary demoulding during shaping and demoulding, otherwise, then can't the demoulding, and secondary demoulding need to arrange secondary demolding mechanism in addition.The secondary demolding structure of realizing now is different, some has the simple structure of use, but also need to adopt the human assistance operation, waste time and energy, some also has the automatic demoulding structure, but too complicated, production efficiency is not high, and the product shaping time is long, and the cycle of production mould is long, production cost is high, is unfavorable for the actual production use.
Summary of the invention
For addressing the above problem, in order effectively to increase work efficiency, shorten the mould production cycle, the utility model provides a kind of secondary automatic demoulding mechanism of back-off mould, comprise front template, the front mould fixed head, rear pattern plate, the rear mold fixed head, the mould pin, front template is installed on the front mould fixed head, rear pattern plate connection mode pin is contained on the rear mold fixed head, described rear mold fixed head is provided with push rod, be provided with face needle plate and end needle plate between described mould pin inside and the fixed head, the face needle plate is provided with back stitching, end needle plate is connected with push rod, pass through push rod, the back stitching easy motion that leads, consist of the die chamber between front template and the rear pattern plate, it is characterized in that: increase again another end needle plate between described rear mold fixed head and the end needle plate, needle plate of the described end is equipped with oblique top greater than the size of end needle plate on the described base plate pin, and the oblique top other end is connected with the die chamber; Described mould pin inside is provided with needle plate of the corresponding end and is provided with the limiting ladder position.
As the further improvement of above-mentioned technology, adopt the nylon plug to be connected between described base plate pin and the base plate pin.
After adopting said structure, during use, impetus power is in push rod, and push rod promotes two end needle plates and the face needle plate moves upward, and when needle plate of the newly-increased end contacts to the position stop motion of mould pin limiting ladder, at this moment the plastic cement back-off spare back-off position in the die chamber breaks away from.The end needle plate that links to each other with push rod continues to move up to and ejects whole plastic, and reach realize the plastic automatic trip from, the utility model structure is the stripping means that an i.e. demoulding campaign realizes Double-ejection simultaneously, twice demoulding campaign once finished, shorten the formed product time, enhance productivity.
The utility model is simple in structure, practical, increases work efficiency and shortens the mould production cycle.
Description of drawings
Fig. 1 is the utility model structural representation.
Be denoted as among the figure: 1 front template, 2 front mould fixed heads, 3 rear pattern plates, 4 rear mold fixed heads, 5 mould pin, 51 limiting ladder positions, 6 push rods, 71 end needle plates, 72 end needle plates, 73 nylon plugs, 8 needle plates, 9 back stitchings, 10 die chambeies, 11 oblique tops, 12 confinement blocks.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not consist of any restriction of the present utility model.
As shown in Figure 1:
A kind of secondary automatic demoulding mechanism of back-off mould, comprise front template 1, front mould fixed head 2, rear pattern plate 3, rear mold fixed head 4, mould pin 5, front template 1 is installed on the front mould fixed head 2, rear pattern plate 3 connection mode pin 5 are contained on the rear mold fixed head 4, described rear mold fixed head 4 is provided with push rod 6, be provided with face needle plate 8 and end needle plate 71 between described mould pin 5 inside and the fixed head 4, face needle plate 8 is provided with back stitching 9, end needle plate 71 is connected with push rod 6, by push rod 6, back stitching 9 easy motion that leads, consist of die chamber 10 between front template 1 and the rear pattern plate 3, it is characterized in that: increase again another end needle plate 72 between described rear mold fixed head 4 and the end needle plate 71, needle plate of the described end 72 sizes greater than end needle plate 71 are equipped with oblique top 11 on the described base plate pin 72, and oblique top 11 other ends are connected with die chamber 10; Described mould pin 5 inside are provided with needle plate of the corresponding end 72 and are provided with limiting ladder position 51.
As further improvement in the technical proposal, adopt nylon plug 73 to be connected between described base plate pin 72 and the base plate pin 71, can be implemented in when moving upward base plate pin 72.
After adopting said structure, during use, impetus power is in push rod 6, push rod 6 promotes end needle plate 71, end needle plate 72 and face needle plate 8 and moves upward, when needle plate of the newly-increased end 72 contacts limiting ladder position 51 to mould pin 5, stop motion, at this moment the plastic cement back-off spare back-off positions in the die chamber 10 break away from.When the end needle plate 71 that links to each other with push rod 6 continues to move up to confinement block 12, reach and eject whole plastic, and reach realize the plastic automatic trip from.Adopt nylon plug 73 to be connected between base plate pin 72 and the base plate pin 71, when moving upward, realize the effect of tension between base plate pin 72 and the base plate pin 71, base plate pin 72 is subjected to limiting ladder position 51 to stop ascending motion, but does not cause the ascending motion of the small distance of base plate pin 71.
The utility model structure is the stripping means that an i.e. demoulding campaign realizes Double-ejection simultaneously, and demoulding campaign is once finished, and shortens the formed product time, enhances productivity.
The utility model is simple in structure, practical, increases work efficiency and shortens the mould production cycle.
