Byproduction, theidealdemouldingeffectofwasacquired. Keywords: injectionmold; fixedmold; ejectiondevice0 ease the introduction of plastic parts ejection depends on the complexity of plastic parts, mold release will have a direct bearing on the quality of plastic parts. Stripping occurs when the dynamic model can be bad out additional top bar and plastic parts of the ejection angle of ejection for poor fixed mold plastic parts, pull, whitening and other phenomena occur, even when moving and stationary mold plastic parts parting remain in the fixed mold cavity, to remove the plastic parts caused great difficulties, has seriously affected production. The following describes the design is scheduled to die top of the organization to address mold plastic parts mold release in the given problem of the poor. One end of the fixed mold plastic parts, poor ejection ejection mechanism design for a side of the slide set of plastic parts and mold stripping bad side of the slider can be delayed approach to the ejection, the plastic parts in the move,[link widoczny dla zalogowanych], scheduled to die sub- mold cavity when the stay in the moving model. Those who do not side slider plastic parts, plastic parts because the quality requirements, draft angle of the chase Received Date :2007-08-09 Description: Xiong Wenjie (1977 a),[link widoczny dla zalogowanych], male, engineer. Plus there is a certain limitation, and therefore the additional scheduled to die on top of the organization must be designed,[link widoczny dla zalogowanych], which is scheduled to die against the top agencies. Figure 1, top of the core anti-rotation molding of plastic parts, plastic parts end ejection occurred in the fixed mold bad ejector mechanism shown in Figure 1 can be designed to turn the top of the anti-core, the top part of the core in the molding of plastic parts, Another part of the move, scheduled to die together with the dynamic model of the core module with the. After the mold assembly shown in Figure 2. Move, scheduled to die mold, plastic molding, the anti-rotation pin 4 does not participate in forming the top part of the dynamic model of the role of the core in the plastic molding to maintain the required position, and back to position by the fixed mold, as shown in Figure 2 (a) below. After cooling plastic molding, move, scheduled to die parting, the anti-rotation top of the core 4 under the action of the spring 2,[link widoczny dla zalogowanych], the top out, so 32DieandMouldTechnologyNo1.2007 set to launch plastic cavity 6, 5, sent off to a smooth model of plastic parts remain in the dynamic model of the core cavity 7, as shown in Figure 2 (b) below, and then push the top of the system through the top of the peak of the staff out of plastic parts. (B) the top of the plastic parts plastic parts in Figure 2 after the end of the top of the fixed mold body 1. Screw 2. Spring 3. Scheduled to die 4. Top 5 anti-rotation pin. Given cavity 6. Plastic 7. Dynamic model of the core 8. Plastic dynamic model 2 the center scheduled to die poor ejection mechanism design plastic parts out of the top center of the ejection occurred in the setting mode when the poor are different from the bad end of ejection, when the top of the core design of all involved in an end of the molding, Figure 1 can not be designed like the top of the core, but by the same principles can also top of the core design, the top core design shown in Figure 3 the top of the core portfolio, the middle part in the molding of plastic parts and top out, both sides of the and dynamic model of the core with. After the local structure of the mold assembly shown in Figure 4,[link widoczny dla zalogowanych], after the top of the plastic parts in Figure 4 (b) below. The combination of the top cell in Figure 3 (b) the top of the plastic parts plastic parts in Figure 4, after the center scheduled to die top of the body 1. Screw 2. Spring 3. Scheduled to die 4. Top 5 anti-rotation pin. Given cavity 6. Plastic 7. Dynamic model of the core 8. 3 Conclusion dynamic model molding of plastic parts, plastic parts are often scheduled to die poor ejection occurred, the use of release agents, mold release additional angle of impact the quality of plastic parts, so there are certain limitations and can not fundamentally solve the problem. Model described in this article the top of the bodies can be a fundamental solution to this problem, through the design of such scheduled to die additional ejector mechanism, the production of ejection and then the problem does not appear scheduled to die. It must be noted that the top of the springs and the strength of institutions should consider in each mold maintenance on a regular basis to check whether the effectiveness of the spring, the top of the action is smooth, or to not produce the desired effect.
