Description

Technical Field

[0001] The utility model relates to the technical field of automobile heat insulation cover moulds, in particular to the technical field of an engine heat insulation cover production mould. Background Art

[0002] When a car engine is running, it will generate a lot of heat, which will be dissipated into the surrounding environment and will have an adverse effect on the surrounding parts of the engine. The engine heat shield acts as a heat insulation barrier, which can block the spread of heat, reduce the temperature in the engine compartment, and protect the engine and other fragile components from overheating damage. In a high temperature environment, the rational use of the heat shield can reduce the loss caused by engine heat and improve power output efficiency. The use of the heat shield can also reduce the interference of the external environment on the engine, maintain the normal operation of the engine, and extend its service life.

[0003] In the production of automotive diesel engine heat shields, stamping dies are required. In the use of traditional stamping dies, it is difficult to effectively buffer the upper and lower dies during stamping work, resulting in vibration of the upper and lower dies during stamping, which reduces the stability during stamping and reduces the service life of the dies.

[0004] To solve the problems raised in the background technology, publication number CN218982897U discloses a mold for producing a heat shield for a vehicle, wherein the first fixing plate is fixed on a stamping device, the second fixing plate is fixed on a stamping platform, a material plate is placed on a lower mold, and the stamping device is started to push the first fixing plate through a second limiting column and a second spring for a first buffering. When the first fixing plate drives the upper mold and the mold core to move downward and contact the material plate, the mold core is buffered for a second time through a slider, a slide groove, a second fixing groove, a first limiting column and a first spring, thereby achieving the goal of buffering and shock-absorbing the stamping mold when stamping the heat shield for the automobile exhaust system, and avoiding the situation in which the traditional mold vibrates due to poor buffering effect during stamping. However, this structure still has the following shortcomings:

[0005] 1. When punching the heat shield, the punching head and the heat shield raw material are squeezed, which will produce leftovers, which will easily stick to the mold surface, thus affecting the molding quality;

[0006] 2. After the product is solidified, it is necessary to take out the molded product. However, since the product is located inside the molding cavity, the staff needs to use tools to take out the product, which is time-consuming and cumbersome. Summary of the invention

[0007] The purpose of the utility model is to solve the problems in the prior art and to propose an engine heat shield production mold, which can use a material receiving trough to collect the punched-down scraps, and cooperate with the material receiving mechanism to collect them in time, and use the ejection mechanism to eject the molded product from the molding cavity, so that the staff can take it easily.

[0008] To achieve the above-mentioned purpose, the utility model proposes a production mold for an engine heat shield, comprising a workbench, a lifting column, a first top plate, a first cylinder, an upper die seat, a punch head, a lower die seat, a connecting platform, a material receiving mechanism, an ejection mechanism, and a controller. A plurality of lifting columns are arranged at the upper end of the workbench, and a first top plate is arranged at the upper ends of the lifting columns. A first cylinder is arranged above the first top plate, and an upper die seat is arranged below the first top plate. The output end of the first cylinder passes through the first top plate and is connected to the upper die seat. A punch head is arranged below the upper die seat, and a lower die seat matching the upper die seat is arranged above the workbench. A connecting platform is arranged on the side wall of the workbench, and a material receiving mechanism is arranged above the connecting platform. The material receiving mechanism is used to collect scraps dropped during the stamping process. The ejection mechanism is arranged below the workbench, and the ejection mechanism is used to eject the formed product. The controller is arranged on the side wall of the workbench, and the controller is electrically connected to the first cylinder.

[0009] Preferably, a plurality of supporting legs are provided below the workbench and the connecting platform.

[0010] Preferably, a forming cavity is provided in the upper middle portion of the lower die seat, and the forming cavity is adapted to the punching head.

[0011] Preferably, a material receiving trough is provided above the lower die base, the material receiving trough is located around the outside of the molding cavity, and the material receiving trough is in a circular structure.

[0012] Preferably, the material receiving mechanism includes a suction machine, a feed pipe, a discharge pipe, and a material receiving box. The suction machine is located above the connecting table. The input end of the suction machine is connected to the feed pipe, and the feed pipe passes through the interior of the lower mold base and communicates with the material receiving trough. The output end of the suction machine is connected to the discharge pipe, and the discharge end of the discharge pipe is connected to the material receiving box.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model can collect the punched scraps through the coordinated use of the collecting trough and the collecting mechanism. When the heat insulation cover performs the punching work, the punched scraps can fall into the collecting trough, and then the suction machine is started. The suction machine sucks out the scraps inside the collecting trough through the feeding pipe, and then conveys the scraps to the inside of the collecting box through the discharging pipe, which is convenient for subsequent staff to handle uniformly, avoiding the fallen scraps from sticking to the mold surface, thereby improving the molding quality, and solving the problem that the scraps are easy to stick to the mold surface and affect the molding quality;

[0016] 2. The utility model can eject the formed product from the forming cavity through the ejection mechanism. When the product is solidified and formed, the second cylinder is started, and the second cylinder drives the ejector rod to move upward. The ejector rod drives the top plate to push up, and then the formed product is ejected from the forming cavity, which is convenient for the staff to take out, improves the processing efficiency, and solves the problem that it is time-consuming and laborious for the staff to take out the product.
