Description
Technical field
The present invention relates to a kind of pet toy, for the dual-color forming module of this pet toy of molding and utilize this dual-color forming module to carry out the double-colored post-cure moulding process of pet toy.
Background technology
Pet toy is a kind of toy for playing to house pet, include house pet male earner, toy ball etc., it meets house pet demand on emotion in face to a certain extent, and also has with the effect all serving critically important in-depth and intensification above the interactive link of owner on physiology. Wherein, pet toy is the toy that house pets are generally hankered after, and this pet toy adopts the materials such as rubber to make, and nontoxic, resistance to especially house pet baits and plays.
Owing to existing rubber vulcanization process can only make monochromatic article, cause existing pet toy in the majority with monochromatic toy, especially for ball toy, it is common on be all monochromatic ball. in order to attract the attention of house pet better, people have been fabricated to double-colored pet toy. but, the manufacture method of pet toy double-colored at present is still extremely original, is generally adopted by manual lagging mode or the method sprayed paint. wherein, the rubber toy that surface lacquer processes is due to containing poisonous and harmful substance, thus cannot function as the toy of house pet. manual lagging mode is first to adopt the toy of the first color of injection mo(u)lding, then manual rubber peel or the lint etc. sticking the second color of grooved area glue on its surface, its shortcoming is in that in double-colored technique easily occur that double-colored chaotic boundary is unclear, alter color, well two kinds or two or more color regions totally can not be distinguished, simultaneously, double-colored bonding force is not strong, the that color sticked is easy to fall off, affect the double-colored quality of product, cause durability degree inadequate, after long-time use, as easy as rolling off a log the coming off of the adhesion on surface causes the damage of product.
Summary of the invention

Therefore, for molding pet toy ball 4 hollow structure inside, described module also includes core bar 3, and one end of this core bar 3 is bulb 31, and bulb 31 is placed in the center of each matrix forming unit, for the hollow structure of molding pet toy ball 4; The other end of core bar 3 is handheld terminal 32, is moved in the striped portion forming unit of striped portion mould 2 for pet toy ball 4, as shown in Figure 4 after matrix 41 molding.
The module advantage of the present invention is in that: present invention employs two molds, the matrix 41 of difference molding pet toy and striped portion 42, after groove 43 on matrix mould 1 molding toy, idiosome after pet toy matrix 41 molding is put into striped portion mould 2, the side block portion 21 ensured on striped portion mould 2 is placed in the groove 43 on matrix 41, carry out the molding in toy striped portion 42, owing to matrix is separated by side block portion 21 with striped portion 42, ensure that on toy, two different colors of partial confines is clearly demarcated, without interpenetrating, material used by molding is nontoxic plastics or rubber, so that toy does not contain any nuisance, simultaneously, in striped portion mould 2, striped portion 42 and matrix 41 are made of one piece, belong to post-cure technique, ensure that on toy, two different colors of part can firmly connect, toy surface is without the phenomenon that comes off occur after a long time use, thus improve durability.
It addition, incorporated by reference to referring to Fig. 5 to, shown in 11, the invention also discloses the double-colored post-cure technique utilizing above-mentioned dual-color forming module to realize pet toy dual-color forming, comprising the following steps:
A, by after matrix mould 1 installation, matrix mould 1 matched moulds, meanwhile, be installed in matrix mould 1 including by core bar 3 so that the bulb 31 of core bar 3 is positioned at the center of each matrix forming unit;
B, fill the matrix material of the first color, carry out pressurize and cooling, it is achieved a sulfur of pet toy simultaneously; Wherein, matrix material selects nontoxic rubber or plastics, it is preferred that matrix material is rubber, and color is allocated by coloring agent;
C, matrix 41 molding complete, matrix mould 1 die sinking;
D, the matrix 41 molding completed remove matrix mould 1, are installed by matrix 41 simultaneously and put in place, it is ensured that the side block portion 21 in striped portion mould 2 puts into the groove 43 of matrix 41 on striped portion mould 2;
E, the striped portion 2-in-1 mould of mould, fill the striped portion material of the second color, carry out pressurize and cooling simultaneously, realize the post-cure of pet toy, wherein, rubber that striped portion material selection is nontoxic or plastics, it is preferred that striped portion material is rubber, and color is allocated by coloring agent;
F, striped portion 42 molding complete, mould 2 die sinking of striped portion, and the pet toy after molding is removed striped portion mould.
Wherein, rubber is one-step building after curing, does not need reprocessing, is a sulfur; What can not reach after once sulfuration that requirement also needs to carry out second time sulfuration is post-cure. Post-cure refers to that rubber reaches certain state of cure (vulcanization), removes thermal source and proceeds to add heat-vulcanized technique. In broad terms, rubber vulcanizes to a certain extent, even if not heating, it still under the effect of waste heat, or in goods storage process, can continue to deepen sulfuration program, or produce to continue crosslinking phenomena under dynamic action. Certainly also include continuing heating and carry out the processing technique of post-cure. Post-cure purpose is that rubber cross-links further, improves mechanical property and the compression set performance etc. of rubber.
Preferably, the locked mode pressure in step a is 160KG～180KG, it is more preferred to, the locked mode pressure in step a is 180KG.
Preferably, the injection pressure in step b is 100KG～140KG, and dwell pressure is 100KG～140KG, and the dwell time is 1s～3s, cool time is 250s, it is more preferred to, the injection pressure in step b is 140KG, dwell pressure is 40KG, and the dwell time is 1s, and cool time is 250s.

Preferably, the locked mode pressure in step e is 160KG～180KG, it is more preferred to, the locked mode pressure in step e is 180KG.
Preferably, injection pressure to be 100KG～110KG, dwell pressure be 100KG～110KG in step e, dwell time are 1s～3s, cool time is 60s, it is highly preferred that injection pressure to be 110KG, dwell pressure be 10KG in step f, dwell time are 1s, cool time is 60s.
Preferably, in step f, after the molding of striped portion, the temperature of pet toy is 150～170 DEG C, it is more preferred to, in step g, after the molding of striped portion, the temperature of pet toy is 170 DEG C.
To sum up, the advantage of present invention process is in that: adopt two secondary moulds, realize the matrix 41 to pet toy respectively and striped portion 42 carries out multistep molding, in the double-colored post-cure moulding process of pet toy, after the matrix 41 completed by matrix mould 1 molding is removed, matrix 41 is installed by striped portion mould 2 and puts in place, simultaneously, ensure that the side block portion 21 in striped portion mould 2 puts into the groove 43 of matrix 41, achieve the post-cure technique of toy, the double-colored post-cure moulding process that the present invention adopts, enough two kinds of different colours substantially distinguishing toy, and without interpenetrating, simultaneously, owing to having cast out the spraying coating process of existing paint, pet toy is made not contain any nuisance, additionally, post-cure technique makes two different colors of part on toy firmly to connect, toy surface is without the phenomenon that comes off occur after a long time use, improve durability.
