Detailed Description

The following is a further description of embodiments of the utility model, taken in conjunction with the accompanying drawings:

As shown in fig. 1-7, a blind hole rubber core mold comprises a lower mold plate 1, a mold core 2, a push plate 3 and an upper mold plate 4; fixedly connected with mold core 2 on lower bolster 1, mold core 2 is used for carrying out the plastic core shaping to product 5, one side that lower bolster 1 is close to mold core 2 is provided with push pedal 3, the one end that lower bolster 1 was kept away from to mold core 2 passes push pedal 3 and exposes in the surface of push pedal 3, the one side that lower bolster 1 was kept away from to push pedal 3 is provided with cope match-plate pattern 4, be provided with die cavity 6 on cope match-plate pattern 4, mold core 2 inserts in die cavity 6.

As a preferred embodiment; a positioning plate 7 penetrating through the mold core 2 is arranged on the lower mold plate 1, and a first mold hole 8 corresponding to the mold core 2 is arranged on the positioning plate 7; through being equipped with locating plate 7, locating plate 7 can be through first nib 8 further fix mold core 2, firstly can realize the location guiding action of mold core 2, secondly can strengthen the intensity of mold core 2 (strengthen the die pole 11 intensity on the mold core 2) for mold core 2 can not cause the deformation or the fracture of mold core 2 in the drawing of patterns of follow-up product 5, and then improves the quality of use and the effect of this mould.

As a preferred embodiment; one surface of the lower die plate 1, which is far away from the push plate 3, is connected with a back plate 9, and the other end of the die core 2 penetrates through the lower die plate 1 and extends to the back plate 9 to be connected with the back plate 9; through being equipped with backplate 9, make it can carry out fixed connection with mold core 2, and then make this mould adopt the mode of fixed mold core 2 to mould, be favorable to follow-up drawing of patterns to product 5.

As a preferred embodiment; the mold core 2 consists of four mold rods 11 which are symmetrical with each other; the end, far away from the lower die plate 1, of the die rod 11 is provided with a shaping part 12, and the shaping part 12 is of an alternate flat round structure; the mould pole 11 and the shaping portion 12 are integrated into one piece structure, and mould pole 11 and this mould fixed connection form fixed mold core 2, are favorable to strengthening the intensity of mold core 2, and simultaneously, shaping portion 12 also just can enter into the die cavity 6 inside of cope match-plate pattern 4 and carry out the product 5 moulding, and no matter moulding process or product 5 drawing of patterns process all have better result of use.

As a preferred embodiment; the push plate 3 is provided with a second die hole 10 corresponding to the die core 2; the purpose of this design is: the second die hole 10 can pass through the die rod 11, and the molding part 12 of the die rod 11 is exposed, so that the product 5 is exposed outside the second die hole 10, and the demolding of the product 5 is facilitated (the product 5 can be effectively ejected under the action of the push plate 3); moreover, the contact area between the push plate 3 and the product 5 is increased, the stress is uniform when the product 5 is demoulded, the product 5 is prevented from being damaged when the product is demoulded, and the defective rate is reduced.

As a preferred embodiment; as shown in fig. 7, gaps 13 are arranged between the pushing plate 3 and the mold core 2 and between the pushing plate 3 and the lower mold plate 1, and are used for connecting burrs into a piece; the purpose of this design is: the gap 13 is L-shaped or mirror image L-shaped, during molding, the sizing material can enter the gap 13, and the distance of the gap 13 is 0.3mm, so that the sizing material in all the second die holes 10 forms a piece after solidification, after the product 5 is ejected out of the subsequent push plate 3, the whole burr can be blown out directly through a fan, the cleaning difficulty is reduced, the burr cleaning time is saved, and the production efficiency is further improved; in addition, the gap 13 near the product 5 is an inclined plane, and the aperture of the gap 13 at the position is smaller than that of the gaps 13 at other positions, so that when the push plate 3 ejects the product 5, the product 5 and the raw edges of sizing materials can be rapidly disconnected.

The working principle of the utility model is as follows: firstly, injecting a product 5 into a die cavity 6, then, closing the die through a lower die plate 1 and an upper die plate 4, at the moment, inserting a die core 2 into the die cavity 6 for shaping, separating the upper die plate 4 after shaping is finished, at the moment, bonding the product 5 on the die core 2, and then, ejecting the product 5 outwards through a push plate 3, thereby realizing the demolding process of the product 5; it is worth mentioning that the utility model protects the mould, so the power involved is located outside.

It should be noted that the main problems in the prior art are: the product is separated from the mold core in a knocking and pushing mode by manpower, but in the mode, the stress is concentrated due to small stress area, so that the product is difficult to demould or damaged, and the defective rate is improved.

Therefore, after the improvement of the application, the push plate 3 is arranged, and the contact area of the push plate 3 and the product 5 is large, so that the stress is uniform when the product 5 is demoulded, the product 5 is prevented from being damaged when the product is demoulded, the defective rate is reduced, and meanwhile, the push plate 3 is adopted to eject the product 5, so that the product 5 is more convenient to demould, the demould difficulty is greatly reduced, the using effect of the die is better, and the practicability is stronger.
