Molded plastic impeller
Should be the side of the hole forming punch size control consistent. Easily lead to Taiwan after the impeller sticky hole wall displacement, affecting the flow of the liquid, while, when fools round pick of the intensity difference, not pretty. Mold design uses a direct forming method: mold on the design side of the eight side holes forming the core, can finish forming the eight side holes,[link widoczny dla zalogowanych], though more complicated mold structure, but it is easy to ensure that mold. Manufacturing cost is lower than the first. Suppression of the product regardless of strength, fluid flow and the appearance of the product better than the first method is the design of 1,1-side of the core (see Figure 2) side of the impeller on the distribution of eight holes, each smaller interval, showing involute distribution, core pulling large displacement, designed to mold to core pulling is difficult. But outside the core pulling the side of the mold core and the mold design and manufacturing is much easier. To ensure that the core in the mold of eight domestic helpers have the correct installation position, the side of the big end of the tail core designed R160mm, so close to the next and then install the two Figure 2 on the surface. Side of the body center and the core chamber 8 under 31 on the heating plate 2 Kids in guide post 3. Convex touch fixed plate 4. Expansion spring 5. Punch inserts 6. Punch 7. Hanging rod 8. Cavity 9.

Limit block spiritus smilingly marrow one hundred and eleven. Eleven thousand one hundred and eleven - post 40 No. Total 1471.2 under 5 die design is a cavity under the model is the positioning of the side core pieces to facilitate installation of the system stroll, will play a role in positioning the part designed to insert lO (see Figure;). On the design of its core compatible with the side of the slot, with Q gap is 0. O5 ~ O. 1Omm. Top surface of bottom die top surface flush with the inserts, inserts and side groove depth on the core size of 28.8mm thickness consistent. 】. 3, the design of movable cavity mold cavity to facilitate the installation side of the core. When the mold cavity and core side and side with the pressure firmly on the lower mold core within the cavity 8 in the plane and the lower die 11 of the top surface of the formation of product type. 1.4 The core activities of design (1) Activities forming the core pieces of the product and locate the position from the side of the core installation. To facilitate the positioning groove processing, the structure will be designed into the mosaic (see Figure 3 Activity-core inserts 15). As the process of the mold side of the core product to suppress a greater role by the arc on the concave side of the core of the lateral force. Thus the core activities of the vessel wall is weak inserts some of the most easily damaged, so this should not be too high hardness, heat treatment of parts, designed for 43 ~ 4SHRC to (2) activity through the set of 20 core l6, l9 connector under the tank connected with the hydraulic press,[link widoczny dla zalogowanych], The role of the product from the top, starting with orientation on the core activities of the role of key and keyway under the model with 1】. Inserts to ensure the positioning of the core activities and the next slot slot slot inserts the correct positioning of the relative position of the side in order to facilitate the installation of the core. The working principle of the mold 2 (see Figure 3) to suppress before the cavity 7 of 8 from the hanging rods hanging on the mold, the product inserts and eight side of the core 9 into the mold, the mold cavity under the exercise of fitting in n the next model after the stop, with four bolts to lock the two into one. At this point the cavity side of the core are fastened. Eight wool can be installed to suppress. After compaction products,[link widoczny dla zalogowanych], first to stop a certain distance upstream on the model, this time hanging on the rod from contact with the mold cavity hanging screws. Remove the four bolts on the lock mode to continue upward. Hang cavity. Hydraulic press cylinder to promote the activities under the core upstream, under the product top of the mold, the core activities of reset. The product on hold in the next top model, the out side of the core 3 out of product design should pay attention to the problem (1) FX501 plastic flow is poor. So, through the side of the core to suppress the resistance of a large gap, so that side of the core of the edge should be not less than the R2 of the rounded corners poured. To facilitate the rapid inflow of plastic under the cavity. (0) 320 on a lower die. mm hole wall and the lower die insert groove and lateral position on the core with the surface not too large. Should be the bottom to the top of the slope from the lO ~ 15. Otherwise the result back over the General Assembly with the mold surface when the side of the core by the limp and damage the mold (3) activities should ensure that the core reset washer 18 together in the bottom 14, preventing an infinite cylinder under hydraulic press down and pull off the screws connecting the core activities. 4, the manufacturing side of the core side of core thickness to ensure the eight dimensions 2S. 8: mE consistency and big end side of the core size of the tail Rl60 consistency, not single pieces of raw materials processing is best to forging a blank disc 330ram, quenching and then by car to reach the grinding requirements of Figure 2,[link widoczny dla zalogowanych], and then cutting out the system Eight side of the core, this will guarantee a good core in the mold is installed on the side of interchangeability is not ten private Cao f} t, pills coriander / oblique angle pin and slide the injection mold by stripping Nice low-voltage electrical plants in Zunyi Huai-Ming Chiu 1, analysis of plastic parts and technology to introduce our factory in the production of electrical products. Have a relatively zt, complex plastic parts (Figure 1). Material for a 161 PF size of the pieces of high precision, smooth surface, may not have marks printed, shrink
