Abstract

The utility model relates to an insert or hit exhaust structure of a silica gel shower head water outlet hole mould; the insert structure comprises a lower die cavity, an upper die insert pin, a lower die garbage position and a lower die thimble; the upper die insert pin is inserted into the lower die cavity; a thimble exhaust structure is arranged below the lower die cavity; the garbage position is arranged below a water outlet of the lower die cavity, and communicated with exhaust clearance; the thimble is arranged below the garbage position, can move up and down under the push-out force, so as to push the garbage position out, and returns. The exhaust structure uses the thimble arranged below the garbage position to push out the silica gel in the garbage position and the rough edges together after a formed part leaves the mould, thus being good for smooth exhaust during the production of the next mould.

Description

Silica-gel gondola water-faucet water-out hole die venting structure

Technical field

The utility model relates to mould, relates in particular to silica-gel gondola water-faucet water-out hole die and inserts to wear or to bump and wear exhaust structure.

Background technology

Existing silica-gel gondola water-faucet water-out hole die is below die cavity, and promptly silica-gel gondola delivery port place causes because of exhaust is bad and lacks material, offers exhaust clearance and is used for the exhaust flash, is used to deposit the silica gel that need overflow because of exhaust and the rubbish position of burr.Along with mould use repeatedly, silica gel that overflow the rubbish position and burr are more and more, cause the exhaust in the die cavity to have some setbacks.

The utility model content

The utility model provides a kind of silica-gel gondola water-faucet water-out hole die venting structure at the above-mentioned defective of prior art, the flash and the burr of the position that can remove rubbish, and exhaust was smooth and easy when next mould was produced.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

Insert and to wear structure and comprise: counterdie die cavity, patrix pin, counterdie rubbish position, counterdie thimble; Described patrix pin and counterdie die cavity are inserted and are worn, and counterdie die cavity below is provided with the thimble exhaust structure; The rubbish position is arranged on counterdie die cavity delivery port below, communicates with exhaust clearance; Thimble is arranged on the below of rubbish position, can move up and down under the effect of ejecting, and the rubbish position is ejected, return again.The utility model is by being provided with thimble below the rubbish position, profiled member ejects silica gel in the rubbish position and burr together with thimble behind mould, and exhaust is smooth and easy when helping next mould to produce.

Bump and wear structure and comprise: counterdie die cavity, patrix pin, counterdie rubbish position, counterdie thimble; Described patrix pin and counterdie thimble bump to be worn, and counterdie die cavity below is provided with the thimble exhaust structure; The rubbish position is arranged on the thimble periphery; Under the effect of ejecting, can move up and down, the rubbish position is ejected, be beneficial to air pressure gun and blow down rubbish, return again.The utility model is by being provided with the rubbish position in periphery, counterdie thimble top, and profiled member ejects silica gel in the rubbish position and burr together with thimble behind mould, cleans out with air pressure gun, and exhaust is smooth and easy when helping next mould to produce.

A kind of silica-gel gondola water-faucet water-out hole die venting structure, preferably, described exhaust clearance is 0.02mm.

As can be seen from the above technical solutions, the utility model is provided with thimble below the counterdie die cavity, and profiled member ejects silica gel in the rubbish position and burr together with thimble behind mould, and exhaust is smooth and easy when helping next mould to produce.

The specific embodiment

Below in conjunction with the specific embodiment the utility model is described in further detail.

Referring to Figure 1 and Figure 2, a kind of silica-gel gondola water-faucet water-out hole die that this use provides is inserted and is worn exhaust structure, and it comprises: product, patrix pin 2, rubbish position 3, counterdie thimble 4 in the counterdie die cavity 1; Described patrix pin 2 is arranged at patrix, when the moulding of counterdie die cavity matched moulds, insert at silica-gel gondola delivery port place with the counterdie die cavity and to wear, insert and to wear structure and between counterdie die cavity and patrix pin 2, exhaust clearance 11 is set, rubbish position 3 is arranged on counterdie die cavity and counterdie die cavity 1 delivery port, between the counterdie thimble 4, it communicates with exhaust clearance 11; Counterdie thimble 4 is arranged on the below of rubbish position 3, can move up and down under the effect of ejecting, and the rubbish position is ejected, return again.

Referring to Fig. 3 and shown in Figure 4, a kind of silica-gel gondola water-faucet water-out hole die that this use provides bumps wears exhaust structure, and it comprises: product, patrix pin 2, rubbish position 3, counterdie thimble 4 in the counterdie die cavity 1; Described patrix pin 2 is arranged at patrix, when the moulding of counterdie die cavity matched moulds, bump with the counterdie thimble 4 of counterdie die cavity and to wear at silica-gel gondola delivery port place, at the counterdie die cavity, and between the periphery, top 2 of counterdie thimble exhaust clearance 22 is set, bump and wear structure, rubbish position 3 is set in the counterdie die cavity and the periphery of counterdie thimble, and it links to each other with exhaust clearance; Under the effect of ejecting, can move up and down, the rubbish position be ejected, again return.

After the mould die sinking, thimble moves upward, the waste material in the rubbish position is ejected, and return again, the exhaust when being of value to next mould and producing is smooth and easy.

As preferred implementation of the present utility model, described exhaust clearance is 0.02mm.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
