Abstract

Disclosed is a manufacturing method of hand-bar and product thereof, which uses needle point plastic injection manner in injection molding machine to manufacture a hand-bar. The hand-bar possesses an inner layer and an outer layer. The inner layer is thin and flat and preformed by punch, provided with at least one through hole. The plastic injection point is positioned at the through hole so as to form the shape of the outer layer. Because an upper mold is provided above the inner layer and a lower mold is provided beneath the outer layer, the lower mold urges the inner layer by means of at least one push pin, allowing part of the pliable material overflow towards neighboring region during the process of plastic injection, whereby the inner layer combines with the outer layer by the through hole. At the same time, the upper and lower molds form the appearance and shape of the outer layer wrapping the inner layer, but the two ends of the inner layer is not wrapped, so as to be clamped between the two molds, such that a elastically slidable hand-bar with small deformation at the inner layer and no molding lines on the appearance is made.

Description

438659 V. Description of the invention (1) The present invention refers to a kind of main body material which has a traditional grip in a hand-held space, and there are two weights in a sliding surface grip. The position of the two sides is more effective because of the method, and the manufacturing method is also required to use the material product to provide a more custom-made inventor's article. The uneven thickness of the injection is about a handle. The composition of the square spear is made of a handle. The door-like state has a long space. If there is a type of grip connected to a suitable grip, the use of a very suitable knot is a better combination. Many, the invention is more in accordance with the way of the ten figures, the appearance of the actual heterogeneous material box must be used on the cross-section to show its own effect from time to time, at this time. Therefore, there is a grip on the body. One end is moved to a soft material. The two ends must be provided with products. Different functions can be used to create problems based on actual needs. There is a good proof that it will be turned into a circle after it is advanced. When you hold it, you will want to say a sliding long hole at both ends for storage. It does not show hard aesthetics. It can smoothly make materials and will be used in the manufacturing process. The items that you want to fill can provide eight pictures to the first side. It is often made. The method of lowering and its system and its manufacture make the handle or arc-shaped grip and it is mainly quite large. The hand will be sore and soft. When the position is not in use, pull out the overall mining structure, and the required design needs to meet the needs' and show the way for developers to carry out the requirements. Try to produce quality from the mold line between the two molds. 'Especially the method. It does n’t take much use, because this kind of plastic is also used for glazing, especially the box-like grip, which is developed. When this type is used, it can be moved to use. There must be a better product. It is different from a single space. It is developed for solution. The injection hole 7 of the hair is shown or the outer layer is due to injection.

438659 V. Description of the invention (2) When the outer layer material is injected, the lower mold part is more likely to flow in, resulting in insufficient supply of the upper mold part, resulting in bad conditions such as hemp surface, twist line, no material, defective parts, etc. As shown in the tenth figure, the upward punching of the outer layer material will occur, causing the abnormal state of the inner layer sheet to arch upwards, forming defective products. In order to solve the uneven thickness of the meat, and try to position the inner layer material At the location, there is the improved research and development of the present invention. ^ The main purpose of the present invention is to provide a method for making a handle and a method for making the same, using the respective characteristics of heterogeneous materials to form a composite structure, with a hard material of part A and a soft material of the outside to make elastic sliding Style grip. A secondary object of the present invention is to provide a method for making a handle and a method for making the same. By using a method of pin-point pouring, a soft material is shot and coated on the outside of the hard material; the hard material layer can not be moved during the manufacturing process. The soft material layer is wrapped outside, which has the advantages of faster production speed and one-time production. It can also ensure that the hard layer can be formed at a predetermined position to maintain its required elasticity. Another object of the present invention is to provide a method for manufacturing a handle and a method for manufacturing the same. The effect of using an outer layer structure to wrap the inner layer structure, especially by the method of pin-point pouring, is to form the outer layer material through the perforation of the inner layer material to form The pressure on the back side also positions the inner layer of the material, which can make better products. The manufacturing method and structure of the present invention are: using the method of pinpoint filling in the injection machine to make a handle, the handle has an inner layer and an outer layer, and the inner layer is thin and flat. Pre-formed with at least consistent

V. Description of the invention (4) Shows the dual-center penetration type, that is, the state of the injection point of injection is 1 or 2, or even a plurality of groups. From the seventh figure, it can be seen that the same-the mold group can Make a pair of finished products at once. To sum up the structure described above, the best structure of the present invention is a shot from the center, using a single glue point 'as shown in Figures 3 and 4', from below the arched inner layer 2 with pressure upward For injection, due to the inner layer $ ,,,. Through holes 2 1, they will first enter the space between the upper mold and the inner layer, forming a balance of two pressures, that is, formed above and below the thin flat inner layer 2 The force of Fang ^ "Heng" means that as shown by the force line in the fourth figure, the balance and immobility in the middle will cause the material that is subsequently injected into the outer layer to form a uniform flow to both sides between the inner layer and the lower mold. That is, the inner layer is fixed, and then the material of the outer layer flows toward both ends and is formed. Because the surface of the upper mold is the outer surface, a thimble cannot be set, and the surface of the lower mold is an inner surface. The setting of the thimble does not directly affect the appearance of course. It can also form a double-hole or porous glue-feeding structure. The biggest benefit it produces is that the outer layer is soft and the inner layer can cover the hard material. The inner layer provides better elasticity and the outer layer provides better compression elasticity. 'For example The inner layer is an iron sheet and the outer layer is rubber, which can be provided. A grip that does not hurt 'and has elastic energy to move and deform the grip. This grip ^ is moved by using the long holes on both sides and the matching box to fix it. Structure to form flattening and pull-out protrusions, and the inner layer is provided with through holes, in addition to promoting flow, and produces a firm fixation between the two layers of the finished product. If it is to promote flow, an exhaust structure can be provided As a result, the outer layer can be formed more quickly and an unprotected surface can be formed. Therefore, the present invention can provide good usability and different products from the past. A completely different production method and system
