Description

Technical Field

[0001] The utility model relates to the technical field of movable templates, in particular to a movable template for manufacturing a cylinder block of an automobile engine. Background Art

[0002] When designing the mold, it is necessary to set multiple guide sleeves and guide pins on the movable template and the static template respectively. These guide sleeves and guide pins correspond to each other one by one and cooperate with each other to ensure the accuracy when the movable template and the static template are closed. This is common knowledge known to technical personnel in this field.

[0003] In existing molds, guide pins are mostly installed in the seat holes on the moving platen by interference fit. Factory operators install them by knocking with a hammer, and it takes multiple knocks to completely install them in the seat holes. When knocking, the guide pins may hit the moving platen due to inaccurate positioning by the operators, which may seriously damage the moving platen. Moreover, the installation by knocking requires greater force, which brings greater work intensity to the operators. Therefore, it is particularly important to improve the installation method of the guide pins of the moving platen. In addition, guide pins installed by interference fit are usually non-removable. Once the guide pins are worn, the mold closing accuracy decreases, and maintenance and replacement are more troublesome.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a dynamic template for manufacturing an automobile engine cylinder block is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a dynamic mold plate for manufacturing an automobile engine cylinder block, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dynamic template for manufacturing an automobile engine cylinder block, comprising a dynamic template body and a guide column mounting assembly, wherein the four corners of the dynamic template body are integrally fixed with guide seats, and the middle of the guide seats are provided with seat holes, and the guide column mounting assembly is correspondingly arranged inside the four guide seats, and the guide column mounting assembly comprises a body, an elastic clip, a rubber pad, a threaded opening, a screw handle, a through hole and a guide column body, an elastic clip is fixed to the bottom end of the body, and a rubber pad is arranged at the bottom of the elastic clip cavity, a threaded opening is opened at the top of the body, and a screw handle is threadedly connected to the inner side of the threaded opening, a through hole is penetrated through the middle of the screw handle, and the guide column body is slidably installed inside the through hole.

[0007] Furthermore, the elastic clips are formed by a ring array of several clips, and a conical surface is arranged on the outer side of the top of the elastic clips, and a rubber pad is laid on the bottom of the array formed by the elastic clips.

[0008] Furthermore, the screw thread handle is threadedly fixed to the machine body via a threaded opening, and an inclined surface which is pressed and matched with the elastic clip is arranged on the inner side of the bottom of the screw thread handle.

[0009] Furthermore, the root of the guide column body is pressed and fixed with the elastic clip, and the end of the guide column body is in contact with and fits with the rubber pad.

[0010] Furthermore, side reinforcing ribs are welded and fixed between the relative guide seats, and the side reinforcing ribs are in an arc-shaped block structure.

[0011] Furthermore, a T-shaped groove is provided on the back side of the movable template body, and a columnar reinforcing rib is provided at the center of the inner part of the movable template body.

[0012] Furthermore, an arch-shaped support plate is integrally fixed to the middle of the movable template body, and hollow grooves are provided at both the front and rear ends of the support plate.

[0013] Furthermore, a boss is provided in the middle of the support plate, and middle reinforcing ribs with a trapezoidal structure are provided on the left and right sides of the support plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model pre-buries the guide post installation assembly in the seat holes of the guide seats at the four corners of the dynamic template body through the arrangement of the guide post installation assembly. When in use, the guide post body is first inserted into the inner cavity of the machine body through the middle through hole of the screw thread handle until the end of the guide post body contacts the rubber pad. Thereafter, the screw thread handle is turned to penetrate into the inner cavity of the machine body in cooperation with the threaded opening. At this time, the inclined surface on the inner side of the bottom of the screw thread handle is squeezed and matched with the conical surface on the outer side of the top of the elastic clip, so that the elastic clip is contracted and closed to lock the guide post body therein. Compared with the prior art using the knocking installation method of interference fit, this installation method is simpler to operate and is also convenient for quick disassembly and replacement when the guide post body is worn.

[0016] 2. When the utility model is in use, the entire movable template body is made of plates and multiple reinforcing ribs connected to each other. Relative reinforcing ribs are arranged between the opposite guide seats and on the force-bearing parts on both sides of the arch-shaped support plate to increase the overall strength. At the same time, the force on the entire movable template body is made more uniform, and the material used is greatly reduced, the overall weight is lightened, and the cost is saved while the strength is increased. At the same time, since the mold can be evenly stressed when the mold is closed, the flash phenomenon of the mold can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

The inner side of the bottom of the screw thread handle 1105 is provided with an inclined surface which is pressed and matched with the elastic clip 1102. A through hole 1106 is provided in the middle of the screw thread handle 1105, and a guide column body 1107 is slidably installed inside the through hole 1106. The root of the guide column body 1107 is pressed and fixed with the elastic clip 1102, and the end of the guide column body 1107 is in contact with the rubber pad 1103. The guide column installation assembly 11 is pre-embedded in the seat hole 9 of the guide seat 8 at the four corners of the movable template body 1. When in use, the guide column body 1107 is first inserted into the machine body 110 through the through hole 1106 in the middle of the screw thread handle 1105. 1 until the end of the guide column body 1107 contacts the rubber pad 1103, then the screw thread handle 1105 is turned, and the screw thread handle 1105 and the threaded opening 1104 cooperate to penetrate into the inner cavity of the body 1101.

At this time, the inclined surface on the inner side of the bottom of the screw thread handle 1105 is squeezed and matched with the conical surface on the outer side of the top of the elastic clip 1102, so that the elastic clip 1102 is gathered and closed to lock it. The guide column body 1107 is locked. Compared with the prior art installation method of interference fit by knocking, this installation method is easier to operate. When the guide column body 1107 is worn, it is also easy to quickly disassemble and replace. The entire movable template body 1 is made of plates and various reinforcing ribs connected to each other.
