Abstract
The invention relates to a plastic mould capable of making a plastic product demoulded smoothly and guaranteeing high quality of the plastic product. The plastic mould comprises an upper template and a low template; a cavity is formed in the upper template; a core is arranged in the lower template; a sliding block and a slide stop block which can stop the sliding block are arranged on the lower template; the upper part of the front end of the sliding block is provided with a protruded hook which is matched with an inner buckle of a product; a shifting block which can shift the sliding block to move forward and ensure that the protruded hook is separated from the inner buckle of the product is embedded into the joint surface of the upper template and the lower template; and a gap S is formed between the front end of the sliding block and the core. The invention overcomes the defects in prior art and provides the plastic mould capable of making the plastic product demoulded smoothly and guaranteeing high quality of a mould and the plastic product.
Description
[technical field]
The present invention relates to one can make the smooth demoulding of plastic cement products and guarantee the high-quality plastic mould of plastic cement products.
[background technology]
Existing plastic mould, has interior button and the interior button distant this situation of distance from plastic cement products end face including plastic cement products.Traditional method is to use button in oblique ejection, like this because interior button is being wrapped and finally causing product to pull by a large amount of glue position from the distant oblique top that causes of distance of plastic cement products end face, and the increase of Mould Machining difficulty, therefore increase factory cost.
[summary of the invention]
The present invention has overcome the deficiencies in the prior art, provides a kind of and can reach the smooth demoulding of plastic cement products and guarantee mould, the high-quality plastic mould of plastic cement products.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
Can make the smooth demoulding of plastic cement products and guarantee the high-quality plastic mould of plastic cement products, it is characterized in that including cope match-plate pattern 1 and lower bolster 2, in cope match-plate pattern 1, be provided with die cavity 3, on lower bolster 2, be provided with core 4, on lower bolster 2, be provided with a slide block 6 and the line position block 7 that can block slide block 6, in slide block 6 upper front end, be provided with and in product, detain the 9 protruding hooks 8 that match, the one side engaging with lower bolster 2 at cope match-plate pattern 1 is embedded with can stir slide block 6 and move forward and protruding hook 8 is departed from and in product, detain 9 shifting block 5, described slide block 6 front ends and the core 4 gapped S in interval.
As abovely can make the smooth demoulding of plastic cement products and guarantee plastic cement products high-quality plastic mould, it is characterized in that being provided with the spring 10 toward sinciput by slide block 6 in described line position block 7 front sides.
As abovely can make the smooth demoulding of plastic cement products and guarantee plastic cement products high-quality plastic mould, it is characterized in that being provided with the skewed slot 51 tilting toward die cavity 3 directions from top to bottom on described shifting block 5, at slide block 6 upper surfaces, be provided with the oblique projection 61 coordinating with skewed slot 51, tiltedly projection 61 can stretch in skewed slot 51.
As abovely can make the smooth demoulding of plastic cement products and guarantee plastic cement products high-quality plastic mould, it is characterized in that described shifting block 5 pins on cope match-plate pattern 1 by screw 11.
As abovely can make the smooth demoulding of plastic cement products and guarantee plastic cement products high-quality plastic mould, it is characterized in that the distance A of described gap S, A is greater than interior button 9 width 2-3mm.
The present invention compared with prior art, has following advantage:
The present invention utilizes shifting block, slide block, line position block, spring etc., just can make the smooth demoulding of plastic cement products, and make plastic cement products reach high-quality.
Have, the present invention is simple and practical again.
[accompanying drawing explanation]
Fig. 1 is the state cut-away view that mould closes after injection moulding;
Fig. 2 be mould just opened a bit apart from time state cut-away view;
Fig. 3 is the state cut-away view when lower bolster is opened to shifting block and has just departed from slide block;
Fig. 4 is the state cut-away view of lower bolster while opening completely, product break away from moulds;
Fig. 5 is that existing plastic cement products has interior button and the interior button schematic diagram from the distant this situation of distance of plastic cement products end face.
[specific embodiment]
Below in conjunction with accompanying drawing, the present invention is described in detail:
Can make the smooth demoulding of plastic cement products and guarantee the high-quality plastic mould of plastic cement products, including cope match-plate pattern 1 and lower bolster 2.In cope match-plate pattern 1, be provided with die cavity 3, on lower bolster 2, be provided with core 4, the common shape that forms product 12 under the effect of die cavity 3 and core 4.
On lower bolster 2, be provided with a slide block 6 and the line position block 7 that can block slide block 6, line position block 7 is fastened on lower bolster 2 by screw.In slide block 6 upper front end, be provided with and in product, detain the 9 protruding hooks 8 that match.The one side engaging with lower bolster 2 at cope match-plate pattern 1 is embedded with can stir slide block 6 and move forward and protruding hook 8 is departed from and in product, detain 9 shifting block 5.Described slide block 6 front ends and the core 4 gapped S in interval.In the present embodiment, the distance A of described gap S, A is greater than interior button 9 width 2-3mm, to guarantee detaining 9 complete break away from moulds in product.
In described line position block 7 front sides, be provided with the spring 10 toward sinciput by slide block 6, to provide elastic force skid-proof piece 6 to block and reach the object of slide block 6 returns.
Furthermore, be provided with the skewed slot 51 tilting toward die cavity 3 directions from top to bottom on described shifting block 5, be provided with the oblique projection 61 coordinating with skewed slot 51 at slide block 6 upper surfaces, tiltedly projection 61 can stretch in skewed slot 51.
Described shifting block 5 pins on cope match-plate pattern 1 by screw 11.
As shown in Figure 2, in the process of upwards opening at cope match-plate pattern, shifting block is also along with cope match-plate pattern moves upward, slide block moves to mold center under the drive that has shifting block and spring, apart from S shortening slowly, the part that slide block is smashed in product slowly deviate from product, in product, button is along with mould is slowly opened and the slowly demoulding.
As shown in Figure 3, if Fig. 3 is the state when patrix is opened to shifting block and has just departed from slide block.Now to mold center, also to move to apart from S be 0 to slide block, and slide block also takes off the part in product button bit smoothly, the smooth depanning of product button bit.
As shown in Figure 4, Fig. 4 is the state that mould is opened the complete break away from moulds of product completely.After Fig. 3 state, slide block is at the elastic force of spring under effect, and the position that it is 0 that slide block is also in apart from S, can guarantee that mould is when next matched moulds like this, and shifting block and slide block do not bump, thereby the smooth matched moulds of mould carries out next injection moulding.
