It is mainly provided by providing heat and pressure to the internal mold of the mold. The polymer composition in the chamber is subjected to the conditions required for the reaction, and the shaping effect provided by the shape of the closed cavity allows the polymer to be formed into a desired predetermined shape for use as a constituent element such as a shoe. The use of such products; because products such as shoes need to have different sizes to adapt to different objects of use, therefore, the mold chambers provided on the forming molds need to have different space sizes, correspondingly, injected or placed. The amount of the polymer composition entered is also different. Among them, in the technical field of molding by means of insertion, in the prior art, the required amount of the polymer component raw material is first molded into a sheet-like blank material through an initial embryo mold, and then prepared. The obtained material is placed in a mold chamber of a molding die for reaction and is finally formed; therefore, in order to cope with molded articles of different sizes, the prior art discloses an embryonic mold as shown in the first figure, which is mainly According to different final molding sizes, different sizes of embryonic molds such as large, medium and small (L) (M) (S) are provided to meet different needs. However, the derivation of the industry is necessary for the industry. The cost of setting up a large number of different sizes of the original embryo molds, and the inconvenience and time cost of replacing the embryonic molds in the process. In addition, in the case of the invention patent No. 09, 011, 0009, the invention discloses a refractory device having a sturdy material, which is provided with a mechanical towel template and a module for sliding 1352656 in the die hole. After the polymer component material is injected into the die hole, the raw material can be filled into the die hole by the movement of the module to mold the initial embryo blank, and when the material amount is changed, the thickness of the blank material is changed. Accordingly, according to the present invention, the blank of the same amount of raw material as the large initial embryo mold (L) can be obtained from the above-mentioned small initial embryo mold (S). However, if the creator finds that the blank molding device provided by the above-mentioned invention patent is used for the blank molding process, if the above method is carried out, the formed blank is on the horizontal area.

Specifically, the molding method (10) of the variable primordial size may be obtained by using a blank molding device as disclosed in the invention patent No. 09,911,0009, in other words, the primordial mold (20) is a genus The technical content disclosed in the prior patent of the invention generally has an upper template (22) 'the middle template (23) is located in parallel below the upper template (22), and the second mold hole (24) The two modules (25) are respectively slidably disposed in the bottom end of the corresponding die hole (24), and the second injection hole (26) is respectively disposed on both end faces of the top and bottom of the middle die plate (23). Passing through the upper die plate (22), a fluid pressure cylinder member (27) is used to drive each of the modules (25) to make it slide in the sliding die hole (24), and Wherein, in the embodiment, the shape of each of the die holes (24) is elongated, and the inner diameter of each of the die holes (24) is similar to that of the conventional large die (L) die, and each The module (25) has an elongated block shape corresponding to each of the die holes (24), and each of the injection through holes (26) corresponds to a position of one end of each of the long holes of the die hole (24). on. According to this, when g is used for the molding process of the blank, the industrial implementation can be performed without replacing the primordial mold (20), and the primordial mold (2 〇) has an original volume of the embryo. The mold chamber (28) is separately molded to obtain large, medium and small blanks (U) (M1) (S1) which are respectively obtained by molding large, medium and small initial embryo molds (L) (MKS). The blank is similar in shape, and the original volume is similar to the conventional large-mold mold (the volume of the mold chamber is the same, so it is described separately. See the fourth figure, when you want to mold and When the primary embryo material (L1) is similar to the original embryo material, the molding method (10) of the variable initial embryo size is carried out by including the following steps. 6 a. Using the embryonic mold (20) b. The initial embryo mold (2〇) is in a mold clamping state, whereby the peripheral side wall (241) of each of the mold holes (24) and the bottom plate side (221) of the upper plate (22) correspond to each other. Between the top side block faces (251) of the module (25), a closed shaped blank mold chamber (28) is formed inside the initial embryo mold (2), and each mold chamber (28) is perforated via the injection material. (26) and communicate with the outside world. C. with the fluid pressure The member (27) is powered to drive the volume adjusting portion formed by each of the modules (25) to slide downward through each of the modules (25) to expand the volume of the corresponding blank mold chamber (28) to a first a volume; and a predetermined amount of the polymer constituent material (3〇) is injected into the corresponding blank mold chamber (28) by the external polymer material injection device. d. The fluid pressure cylinder member (27) drives the volume adjustment portion to cause each of the modules (25) to be displaced upward in the corresponding die hole (24) to the volume corresponding to the blank mold chamber (28) from the first grain product. Returning to its original volume, and during the movement of each module (25), pushing the raw material located on the side of the blank mold chamber (28) to fill the blank mold chamber (28), according to Producing a first type of billet similar to the original volume of the blank mold chamber (28) (31) wherein the shape, size, volume and amount of the first type of billet (3Ί) are different from the conventional use. The large embryo mould (L) is similar to the large billet (4), which can be used as the embryo of the large-size final molded product. Please refer to the fifth figure for the molding and application. When the blank (M1) is similar to the blank, the molding method (10) of the variable initial embryo size is the same as the above, and the difference is only in the e-step, In the original volume of the cavity mold chamber (28), and when the time step is performed, the injected polymer component material (10) is filled with the blank mold _) The billet chamber (4) flows in the direction of the long axis to occupy a portion of the sample chamber (28), which is obtained by molding, and the second volume is smaller than the original volume of the billet chamber (28). The billet (32), further step-by-step, 'the second crane billet (32) 73 series is similar to the billet billet (M1) type disclosed in the system, and can be used as a medium-sized final molded product. Primitive use. For the continuation, please refer to the figure in the sixth figure. When you want to mold the blanks that are similar to the conventional small blanks (4), the steps are the same as those of the five-carrying materials. And according to the molding, a smaller second type of blank (32) is obtained for use as an embryo of a small-sized final molded product. By the implementation of the above method, the molding method (1〇) of the variable primordial size can respectively mold the first or second type of billet (31) according to the amount of different raw materials injected ( 32) (32), and the difference in the size between the different types of blanks is mainly concentrated on the change of the horizontal area' instead of the thickness change of the first uncovering technique, so that the embryos of the type can be made The material has a short distance from the wall of the cavity of the molding die, so that the raw material flows uniformly in the molding cavity, and the quality of the final molded product is ensured. In addition, the applicant must specifically mention that there are three: First, in the step c of the molding method (10) of the variable initial embryo size, the volume of the winning mold chamber (28) is enlarged to The procedure of the first volume is not a necessary step. In detail, the step of enlarging to the first volume is performed only to reduce the back pressure of the polymer component raw material during the injection to reduce the injection. The required pressure, and providing a deeper depth of 1352656 degrees, so that the main constituent material of the main/incoming element can be properly accommodated in the space at one end of the long axis of the blank mold chamber (28). It is necessary to mold the first type of blank (31), but it is not necessary to mold the second type of blank (32), which is mainly based on the amount of raw material injected. Depending on how many. First, after the step c, the polymer component material is injected into the space of one end of the long axis of the corresponding blank mold chamber (28) to mold the second type of billet (32) (32, And ensuring that the second type of blank (32) (32') corresponds to the direction of the wall of the long axis end and the short axis of the blank mold chamber (28), thereby obtaining the mold chamber from the blank ( 28) imparting a shaping effect to the shape such that the unshaped portion exists only in the direction corresponding to the other end of the major axis of the blank mold chamber (28). However, such conditions are for molding the first type embryo. In the case of the material (31), it is not necessary, that is, the condition that the polymer component raw material is injected from one end of the long axis of the corresponding blank mold chamber (28) is only an optimal implementation state, and not the only feasible embodiment. . Thirdly, when the step d is carried out, the volume adjusting portion can reduce the volume of each of the blank mold chambers (28) to its original volume, and it can further advance the billet according to actual needs. The volume of the mold chamber (28) is reduced to be smaller than the second volume of the original volume: one can be adapted to the size of the final molded product, not only the three sizes of large, medium and small, that is, the size and variety of the final molded product. Therefore, by reducing the volume of the blank mold chamber to the second volume, the amount of the polymer mass that is measurable is relatively long between the thickness and the horizontal area to obtain the maximum possible horizontal area, thereby Reducing the distance that the raw material flows in the cavity of the molding die; the other 'the polymer of the minerals can reach different compression, and the density is different' to mold the first-type embryo In the case of the material (31), the grain of the blank mold to (28) is further reduced to the first volume in the step [S] 9 1352656, so that the first type of billet is reduced. Thickness to achieve an effect of increasing its density; further, A larger horizontal area or a different density of the billet can be obtained by changing the pressure provided by the fluid pressure cylinder (27), but the change in the pressure value is required to meet the actual demand. And the scope of change, and its scope also has different numerical requirements in response to different models. It cannot be generalized, but it is important for those who are familiar with the technology to learn without excessive experimentation. There should be no specific explanation for the value of this.
