Abstract

The utility model relates to a processing device for a timing gear of an automobile engine. The processing device comprises a wooden box, a forming mould plate, a guide top rod, and a pedal thrust rod, wherein the wooden box is arranged on the forming mould plate in a movable mode, the guide top rod penetrates through the forming mould plate and tightly and fixedly connected with the wooden box, and the pedal thrust rod is connected with a free end of the guide top rod. When the device works, after mould sand is filled in the wooden box and tamped, certain stress is applied to the pedal thrust rod to drive the guide top rod. After the guide top rod ejects from the wooden box, a timing gear sand mould is obtained. The processing device is simple to operate, greatly improves labor productivity, reduces production cost and labor intensity, is high in manufactured element size and stable in quality, and ensures product property.

Description

A kind of processing unit (plant) of timing gear ofr automobile engine

Technical field

The utility model belongs to the machine casting field, particularly a kind of processing unit (plant) of timing gear ofr automobile engine.

Background technology

It is that raw material add man-hour that timing gear ofr automobile engine adopts spheroidal graphite cast-iron; Because size is little, cast(ing) surface requires high, if adopt traditional serial type mould structure processing; Die size is big; Need various big-and-middle-sized equipment to cooperate and to process, so manufacturing cost is higher, is only applicable to the foundry enterprise production of scale.

The utility model content

For overcoming above-mentioned defective, the technical problem that the utility model will solve provides a kind of simple to operate, safe and reliable and be applicable to the timing gear ofr automobile engine processing unit (plant) that all kinds of foundry enterprises are produced.

A kind of processing unit (plant) of timing gear ofr automobile engine, this processing unit (plant) comprises: die model case, forming panel, guiding push rod, foot-operated distance rod; What the die model case was movable is positioned on the forming panel, and the guiding push rod passes forming panel and the die model case is fastenedly connected; Foot-operated distance rod links to each other with the free end of guiding push rod; During work, in the die model case, insert molding sand beat real after, foot-operated distance rod is applied certain power drives the guiding push rod, obtain the timing gears sand mold after the guiding push rod upwards ejects the die model case.

Adopt the utility model processing unit (plant) simple to operate, improved labor productivity greatly, reduced production cost and labour intensity, and the product dimensional accuracy is high, steady quality can guarantee properties of product.

Description of drawings

Fig. 1 is the structural representation of the utility model timing gear ofr automobile engine processing unit (plant).

Among the figure: 1-die model case, 2-forming panel, the 3-push rod that leads, 4-rides distance rod.

The specific embodiment

In actual production, the raw material of timing gear ofr automobile engine nearly all are to adopt spheroidal graphite cast-iron.If the employing traditional processing method, manufacturing cost is higher, and equipment is also had certain requirement, is not suitable for producing in enormous quantities.In order to satisfy the needs of market and production, the technical staff improves the processing unit (plant) of producing timing gears.

Timing gears are made mould as shown in Figure 1 behind the somatotype of center.The mould structure of the utility model comprises: die model case 1, forming panel 2, guiding push rod 3, foot-operated distance rod 4.1 movable being positioned on the forming panel 2 of die model case, guiding push rod 3 passes forming panel 2 and is fastenedly connected with die model case 1, and foot-operated distance rod 4 links to each other with the free end of guiding push rod 3.When work; Die model case 1 is positioned on the forming panel 2; In die model case 1, insert molding sand beat real after, on foot-operated distance rod 4, apply certain power, utilize the conduction of mechanism that power is transferred to guiding push rod 3; Guiding push rod 3 obtains needed timing gears sand mold up and down after upwards ejecting die model case 1, reaches the effect of moulding.

The advantage of the utility model timing gears mould structure is: adopted special shape mo(u)lding box and common guide-bar mechanism to realize moving of semi-automatic sandbox; Thereby simple to operate, improved labor productivity greatly; Production cost and labour intensity have been reduced; The product dimensional accuracy is high, and steady quality can guaranteed performance.Being very suitable for medium-sized and small enterprises produces in enormous quantities.
